Presence of New Forms of Intercultural Communication in Higher Education: Emojis and Social Interactions through WhatsApp among Graduate Students

Communication processes are part of human life. Information and communication technologies (ICTs) and, especially, the use of smartphones have generated new forms of interaction and communication, both synchronous and asynchronous, in formal and informal spaces. One of the most used applications is WhatsApp, which allows the sending of text, documents, images, and emojis. It is important to study these new forms and languages of communication in higher education because any educational or training process is essentially communicative. This research was carried out using a mixed approach, with a nonexperimental, descriptive, and transversal design, using a technique of a survey made up of 30 items. It was applied to postgraduate university students to determine their use and value among people with a consolidated university academic career, which would allow us to determine the presence of these new languages in this context. The basic objectives were to identify the frequency of use of emojis through WhatsApp amongst Mexican graduate students and to analyze the advantages and disadvantages of their use. The results confirmed the increase of emojis in conversations conducted by WhatsApp among fellow students. As positive elements, it was determined that they favor the development of a pleasant environment, confidence, and empathy, in addition to expressing emotions, feelings, and reactions. However, emojis also have drawbacks and disadvantages. Among them is the risk that they are misunderstood since their meaning is not shared, that they divert attention from a central idea, and, in general, that they sometimes have an addictive character that implies a waste of time in a study context, such as at the university. In conclusion, it can be argued that ICTs are profoundly transforming the processes of written communication in today’s society, including the university world. New languages that present intercultural, dynamic, dialectic, and ecosystemic alternatives to speech or writing have appeared. Emojis, in the context of higher education, would be an example of this trend.


Introduction
Communication is one of the indispensable activities for human beings to live together in society and generate knowledge [1,2]. It allows them to expose ideas, points of view, opinions, comments, feelings, emotions, and moods about a certain concept, fact, or situation. In a written way, it is formed globalization that the technological revolution is promoting are present in it. This is even more so if we take into account, as is clear, that every educational or training process is, above all, a communicative process [41,42] in which writing and knowing the influence that the digital revolution has on it is fundamental.

Presence of New Forms of Communication in Higher Education
It is in this sense that the interest in investigating the new writing languages has recently increased significantly from different disciplines such as psychology, medicine, communication, law, and education [43]; added to this is the protagonist that emojis gain in the conversations employing different applications such as Facebook, Twitter, and WhatsApp, both person to person and in groups, which reduces the response time but, at the same time, displaces conventional practices [44][45][46].
Some research that revolves around this object of study has questioned how communicative processes are carried out and the changes generated through writing, which has increased the speed of response and sometimes neglects questions related to grammar and spelling [20,47,48].
Particularly with the use of emojis, one finds studies related mostly to the practices of young university students and, particularly, to the processes of writing, grammar, and spelling. Focusing on the Spanish-speaking context, for example, contributions in this sense and with diverse research approaches are increasingly frequent: Prieto-Terrones and Sanz-Martin [49] analyze the acceptance of writing in virtuality, mainly through WhatsApp, where it is recognized and accepted by users, highlighting the ease it has for quick communication; Cantamutto and Vela [50] conducted a comparative study where they analyze the interactions of WhatsApp and incorporating emojis amongst students from Argentina and Spain; Giraldo et al. [20] analyzed grammar and writing with the use of technological tools; Giraldo [51] reflected on the traditional way of writing and the writing carried out by WhatsApp users, mainly young people; there are also studies on university students related to spelling and text messaging [52] and the general use of WhatsApp by higher education students [5].
Rodríguez-Morales and Rodríguez-Salazar [53] developed interesting research on the communicative practices of young people from the use of mobile technologies and their different applications and the handling of written language by incorporating symbols, emojis, and emoticons, which allow them to express emotions and reiterate points of view. Among the major results is the interest in internal messaging; they can use distinct possibilities to express an idea, for example, in text, video, audio, images, and emojis.
To a lesser extent, there are studies of emoticons or emojis on other educational levels; for example, the written norm in the conversations of postgraduate students was analyzed by Rodríguez-Morales and Rodríguez-Salazar [53]. Rubio [54] also covers this object of study but with students of basic primary education, where the children's interest in improving relationships and the climate generated in the classroom is reflected.
In a more general area, studies related to emoticons or emojis can also be identified from other themes and disciplines, for example, the analysis of feelings from their use [55], the multilingual author in social networks from the n-grams of characters of grammatical tags [16], the development of text summaries through the use of digital tools [18], or an investigation of the frequency of use in older adults [56].
Maíz-Arévalo [57] associates emojis with informal texts in virtual spaces such as sending emails, participating in chats using WhatsApp and Facebook, and using Twitter. However, it is also important to reflect on whether they are used in more formal spaces, their frequency of use, and the functions they perform. Rodriguez et al. [58] research the use of emoticons from the evaluation of seven dimensions: (i) aesthetic appeal, (ii) familiarity, (iii) visual complexity, (iv) clarity, (v) reflection of positive or negative emotion, (vi) emotion, and (vii) the meaning attributed to it.
Analyzing the main research on the problem, it is identified that the predominant age group for this type of study are university students. Moreover, there is a gap around the research with graduate students and the frequency of use of emojis in the WhatsApp groups they generate with their classmates, as well as the advantages and disadvantages they identify in this type of language. Some researchers stress that they are used only in informal spaces, and others point out they have also been incorporated into formal spaces. Therefore, with this research, we want to fill this gap and focus on identifying the use of emojis in WhatsApp by graduate students, who have a long history in academia and can give us a better reflection of their employment in higher education. This will also allow us to observe the advantages and disadvantages of their use in the context studied. We consider that it is relevant to establish a study of these characteristics since it is located in formative contexts that have been little studied previously. They have almost always been carried out from a social perspective. Knowing the current situation in an educational environment can be very interesting to establish the evolution that these new languages may experience in the future and their impact on education.

From Emoticons to Emojis
It is, therefore, necessary to clarify some issues in the context of research. The main one is that today, one of the most used innovations is emojis [59][60][61], which are incorporated into the conversations that take place in chats through the use of different technological tools such as Facebook, Twitter, WhatsApp, and Hangouts. All of them respond to communicational acts such as gesticulation, the reaction to a situation [62], the manifestation of emotions, moods, and feelings [1], and they somehow replace the facial expressions that are a fundamental aspect of face-to-face conversation and include images that characterize the communication of people who share certain tastes, interests, and objectives [63].
Although the term emojis is mentioned in some texts as a synonym of emoticons, it is necessary to establish a distinction between both, as well as to identify the historical moment in which each of them starts to be used. In the Spanish-speaking context, in which we are located, and according to Real Academia Española (RAE), emoticons are defined as "the representation of a facial expression used in electronic messages to allude to the state of mind of the sender". It is a neologism that comes from emotion and icon, which refers to the emotion and the image. They are used particularly in TMCs, where they are considered a resource that allows conversations to be printed with gestures and handled as immediate feedback in the communicative process [64].
The invention of emoticons is attributed to Flahlman from Carnegie Mellon University, USA, who, three decades ago, represented a smiling face with punctuation marks using the computer keyboard, creating the symbol using three signs :-), and also used :-( to represent a sad or angry face. Originally, these combinations of symbols from a computer keyboard were used to identify jokes in a scientific computer forum; however, later, their use became widespread in TMCs to save time. They are defined by Cheng [14] as graphic representations of facial expressions that are embedded in electronic messages.
The origins of the term emoji are in Japan in early 1999, with the creation of i-mode, a mobile platform with Internet access designed by the company NTT DoCoMo. Shigetaka Kurita is considered the author of the design of 176 pictograms and gestures, with a size of 12 × 12 pixels, which were associated with Japanese culture and allowed the representation of emotions, objects, people, and animals [65][66][67]. Little by little, the emojis were extended to represent emotions in the systems of messaging [64].
Raimondo et al. [65] defined them as a paralinguistic element and also confirmed that their use in conversations has favored more expressive and informal communication, which is characterized by the graphic representation that each has, besides the diversity of meanings that can be attributed to it, from interpreting each user [64]. Its evolution and its acceptance have been such that it is considered a new language in today's society; the variety of designs is increased rapidly by incorporating new characters that contextualize situations that are lived, including news and events [59].
Currently, the number of emojis has exploded; they are added every year to Emojipedia, a term used by Jeremy Burgue in 2013 to refer to the encyclopedia that defines the icons on the web, which is in the following link: https://emojipedia.org/, where the different emojis are defined. Recently, there were about 2000 emoticons and emojis.
Montenegro and Hermenegildo [64] say that the WhatsApp application is one of the most widely used technological tools today to establish communication with people asynchronously, make alls, share files, as well as images, videos, and audios. One of the most widely used resources in conversations are emojis, which facilitate the development of graphic messages that are incorporated into the talks through this application. They express gestures, emotions, feelings, and moods, including people and objectives [68][69][70].
The language used with the WhatsApp application has had such acceptance by users that you can already find words in Spanish as "vamos a wasapear", (exchange messages in WhatsApp) and "te mando un wasap" (message sent by WhatsApp). The RAE [71] has recognized this terminology as adaptations of the Spanish language.
The use of emojis in WhatsApp is based on Emojipedia and the approvals made by the Unicode Consortium. One of its most recent versions is 2017, which included 8518 new characters, and, of these, 56 corresponded to emojis (you can now talk using 136,690 characters, which include both emotions, faces, people, animals, nature, food, drink, travel, symbols, flag, and weather issues). This is a relatively recent phenomenon, which has not been studied in depth [72].
The incorporation of emojis in conversations has been justified by science, considering the following reasons: (i) increase in popularity of social networks, (ii) reactions by people when reading a message where they are included, (iii) they facilitate their inclusion in formal and negotiation spaces, (iv) they soften critical messages, (v) they make people seem more friendly and competent, (vi) they favor the development of virtual learning environments, and (vii) they can establish a correlation with happiness in real life [73].
Some authors [64,74] have pointed the interaction with emojis in the development of a conversation mediated by computers through the use of technological applications; in this case, WhatsApp favors the transmission of ideas and feelings, emphasizing content, views, and opinions. Sometimes, they replace the use of words, statements, or phrases with the use of a single image or a group of them; however, it also specifies that the meaning may vary from person to person, depending on the context, previous knowledge, references, characterization of the situation, as well as the degree of confidence that exists with the people with whom we communicate, whether friends, family, coworkers, fellow group members, authorities, partners, or collaborators.
In short, we are facing a new form of intercultural language that has a powerful presence in our society and is used by university students. It is worth asking, therefore, to what extent it has a presence in higher education and what use is made of this form of communication in this scientific and cultural space of such social relevance [75].

Objectives
We have determined that there is virtually no research on graduate students, the highest level in the academic world. It is very interesting, therefore, to identify the use of emojis in the WhatsApp application as a form of communication by this group. It should be borne in mind that graduate students are the ones who have been in the university environment for the longest time and, therefore, will offer us a more effective view of the rootedness that exists in the use of this symbolic language in higher education.
Therefore, we seek three objectives in this research: (i) to identify the frequency of use of emojis on WhatsApp in groups of graduate students; (ii) to analyze the advantages and disadvantages that these university users find in the incorporation of emojis into WhatsApp conversations, and (iii) identify the reasons college students use emojis.
To achieve these objectives, we place ourselves in the context of an exploratory study. The theoretical framework of the scientific architecture used is based on establishing, from the state of the question, the description of the current situation of the use of emojis as a new form of intercultural communication emerging in the digital paradigm. Additionally, it is especially interesting to place it in the field of higher education and to know the characteristics of this use within formative contexts and not only the social context, as it has mainly been done.

Study Design and Sample
This research was developed from a quantitative approach with a nonexperimental, descriptive, and cross-sectional design [76][77][78]. The technique used was the survey, which allows the use of a set of standardized procedures in research that enables the collection and analysis of data from a sample of representative data from a population [79]. We used the information collection instrument "Survey on the use of emojis in WhatsApp communication with group mates", created by us, which was applied to 103 subjects.
We developed a questionnaire consisting of 30 items, organized as follows. The first part is on sociodemographic data and the use of WhatsApp. It is composed, therefore, of two blocks: a first block, where identification data was requested: (1) age, (2) sex and (3)  The second part is composed of three blocks that are focused on knowing the different aspects of the use of emojis. The first block of this second part focuses on the reasons for the use of emojis in WhatsApp conversations, particularly in groups with fellow students (Items 1-21) and is distributed in different sections, for which a five-point Likert type scale is used with the following response options: always (4), almost always (3), sometimes (2), rarely (1), and never (0). A second block (Items [22][23][24] consists of open-ended questions about the more commonly used emojis, as well as advantages and disadvantages of use.
For the validation of content, the expert method was used [80] so the participation of 12 experts was requested, who have as their line of research the generation and application of knowledge and the use of technologies in a didactic way. They were invited to participate by email and, after their acceptance, they were sent a form on Google, where they evaluated each item from two perspectives: the first, if it belongs or not to the study construct, and the second, where they considered aspects of writing, relevance, coherence, and clarity. The analysis of their contributions allowed adjustments to the questionnaire and thus ensured the understanding of it.
Once the content validation was carried out, the questionnaire was applied to a pilot group made up of 50 subjects with similar characteristics to those it was subsequently applied to. For its part, the reliability of the scale has been evaluated with Cronbach's alpha (α). Except for the items related to the reference variables, in the items with a similar scale, an estimated coefficient of 0.92 was obtained on average. It exceeds the conventional levels, which denotes the high internal consistency of the questionnaire.
The sample was intentionally selected using a nonprobabilistic sample that consisted of 103 subjects who were studying for postgraduate degrees (master's and doctorate) in different Mexican universities, linked to the Educational Sciences, and who use WhatsApp as a technological application to get in touch with their fellow group members to establish one-to-one or group communication, highlighting as the main characteristic the use of emojis in their conversation. Most of the subjects taking part were in the age range of 23-35 years (74.7%), 36-40 years (19.4%), and over 40 years (5.9%). Of the total sample, 25 (24.3%) are men, and 78 (75.7%) are women. In terms of occupation, the majority of those surveyed were teachers, which corresponds to 81.5% or 84 participants.
The application of the instrument was carried out online, using specific software for this purpose, and an invitation was made to respond to it by email. The protocol followed all the guidelines of the Ethics Committee of the universities to which the members of the research team belong. The Codes of Good Practice for Research on Human Beings were followed, which were collected by these committees and signed, and the study was registered by the research team that integrated the authors. All participants gave their informed consent, following the Declaration of Helsinki. The instrument used to collect the information, in the form of an online questionnaire, guaranteed confidentiality and anonymity. Participants had to accept the ethical conditions and give their consent before accessing the questionnaire and submitting their responses.
To process the information, the information matrix of the electronic form was exported to Microsoft Excel ® 2016 software, where the values of mean (X), standard deviation (s), and minimum and maximum were determined. Pearson's correlation coefficients were calculated using GraphPad Prism ® 8.0 software. Pearson's chi-square test was also applied with SPSS ® Statistical Software version 25, calculating the descriptive statistics according to each variable and category. The reason for applying these tests was to determine if there were significant differences in the sample in gender, age, or occupation. For example, if women use more emojis than men, or if the younger participants use them more than the older ones, or if, in some specific professions, they are more frequently used or used in a different way.

Results
Briefly, 100% of the respondents answered that they use the WhatsApp application on their cell phone. Of these, 102 (99%) use it daily, and 1 (1%) use it more than once a week. These data confirmed that the use of technological tools has increased considerably and in activities related to communicating clearly, such as WhatsApp.
Regarding the use of emojis in a conversation when chatting with fellow group members, 95 students (92.2%) responded that they use them, and 8 (7.8%) responded that they do not use them when developing a conversation concretely when establishing communication with their peers.
As for the reasons why they use emojis in the conversations they establish with their group mates, from the answers obtained, the mean (X), standard deviation (s), and minimum and maximum were calculated. This is shown in the following tables (Tables 1-5   The category of social interactions comprises 9 items, the broadest one being where keywords such as closeness, empathy, socialization, trust, cohesion, interaction, friendly atmosphere, pleasant conversation, and mediation can be observed. The highest score is obtained by Item 8 (Make the conversation more pleasant), with an average of 3.31, and the lowest is reflected in Item 5 (Strengthen group cohesion), with 2.78, presenting a difference between both of 0.53. In general, the evaluation is positive for each of the items since all of them are above 2.5 (all this with the minimum in a range of 0 and the maximum in a range of 4).
This category presents the expression of emotions, moods, and feelings when using emojis, where the highest average corresponds to Item 10 (Expressing my emotions), and the lowest standard deviation is 1.28, so the dispersion of data is lower, which reflects that the participants identify in the emojis a resource to express their emotions during the development of the conversations with their group mates. The item that gets the lowest score is 12 (Sharing my feelings). As in the previous category, a minimum of 0 and a maximum of 4 are presented as ranges. The third category is composed of the use of emojis as a resource for understanding messages. It is made up of 5 items, where the highest average is for Item 13 (To better understand what you want to express), that is, besides the written text, its meaning is reinforced by the use of emojis; the lowest average is obtained by Item 16 (Express doubts), with a 2.55, getting a difference between the highest and lowest scores of only 0.32. Once again, the minimum range is 0, and the maximum is 4.
Finally, in the fourth group, the items related to writing are identified (those made up of four), where the highest average is for Item 19 (Send answer more quickly) and Item 20 (It is more practical), with 2.68; the one with the lowest percentage is Item 18 (Save words). The questionnaire also offered three open questions to deepen the information previously obtained and to carry out a qualitative analysis of these responses. From Item 22 (Which emojis do you use most frequently?), a total of 290 responses were generated, with the participants mentioning one, two, or three emojis that they use most frequently. The way they stated them was by describing the emoji, writing down an emoticon (i.e., using the signs on the keyboard), or copying and pasting the emoji. In total, 79 emojis were identified as being the most frequently used in the conversations with their fellow students, generated in WhatsApp. How they were mentioned by the participants was respected; the results are shown in Table 5.
The first column lists the emojis mentioned by the participants as they wrote them in the survey, the second column shows the number of emojis, the third column shows the frequency with which they were used, and, finally, the fourth column shows the percentage that corresponds to that frequency, according to the total that was 79.
As can be seen in the results, which are presented in ascending order, that is, from the lowest percentage to the highest, the highest percentage is the happy face with 42 percent. It is followed, in second place, with 22.35%, by the smiling face. The third place is occupied by the finger pointed up, with 21.17%; the fourth place corresponds to present emotions of sadness and also of anger, with 17.64%; in fifth place is the kiss with 12.94%. These results confirm previous studies where different cultures across the East and the West were taken into account [81]. By contrast, another review of this topic indicates that the most popular emojis are "heart" and "tears of joy" [82]. In this sense, recent studies have confirmed that, depending on the culture considered, significant differences in the interpretation of the most commonly used emojis can be found [83]. Thus, the influence of different platforms and cultural heritage on the frequency of using a specific emoji is an aspect that needs further research.
Through an open question, the students were asked to write down the advantages they find when working with emojis in the conversations through WhatsApp that they have with their classmates with whom they study in graduate school, generating 132 responses. The reason why it exceeds the number of students is that several of them mentioned two reasons in this space.
After the analysis of each of the answers, categories were generated, making a total of 17. In Table 6, a list of these are presented in alphabetical order; in the second column, the frequency in which they were found is presented, and in the third column, the percentage they represent. Within the highest percentages are, first, with 34.09%, that the use of emojis in a group of colleagues on WhatsApp promotes an atmosphere of greater confidence, being relaxed, more closeness and collaboration, and being more flexible, which favors the flow of communication. In second place, 19.69% say that incorporating emojis to the conversations allow us to express, in some way, emotions, feelings, moods, and reactions. In principle, this is a help in this space of communication that is carried out asynchronously through technological tools most of the time, where, from the perspective of the participants, this use makes it possible not only to express ideas but also emotions. In third place, with 8.33%, it is described that it increases agility in the conversation and the speed of response.
As for the disadvantages of the use of emojis, specifically in WhatsApp conversation groups with fellow students, as the previous question was of open structure, 103 answers were generated. They correspond to the number of participants; from their analysis and review, 12 categories emerged, which are presented in alphabetical order in Table 7 (mentioning the frequency of occurrence and the corresponding percentage). Table 7. Disadvantages of using emojis in student groups. Source: own elaboration.

Category Frequency Percentage
Misunderstand what was meant 37 35 The results reflect that the most frequently mentioned category is that the use of emojis can produce misinterpretations in what was meant, with 35.92%, because many times, in the participants' comments, there is a different definition or interpretation of emojis. They also mentioned that it depends on the mood or the moment they read the WhatsApp message, as well as, sometimes, the update number that their smartphone has and the type of operating system. It follows, 15.50% found no disadvantage of the use of emojis. Furthermore, thirdly, with 14.56%, they found that the message can confuse or be ambiguous, as they mentioned that, sometimes, the reduction or elimination of words is increasingly frequent, and the interpretation is left only to the emojis used.
It should be added that, as we indicated, Pearson's chi-square test was also applied to calculate the descriptive statistics according to each variable and category, but no significant differences were found in the sample (gender, age, occupation). No dependency relationship was found; the significance value was greater than 0.05 in all cases. The use, therefore, of this communicative form by this group is very similar, even though it is a heterogeneous group.

Discussion
It is important to note that this type of language does not arise with the use of WhatsApp, but with the handling of signs to represent faces, mainly with moods of joy and sadness (for which the colon, semicolon, and parentheses were originally used). However, with the development of ICTs, these have been modernized and diversified in an accelerated way through different software and the use of the smartphone, which has generated interest in investigating this type of communication, which is carried out through technological tools. All of the above, however, are still in the process of development.
Investigations that delve into the study of this type of language have been carried out on different age groups [3,15], in older adults [56], with university students being one of the most analyzed groups [4,5,14,18,20,50,52]. However, in our case, we have additional information on the use of emojis in the field of graduate studies, i.e., students with a long history in the university world. In this sense, it contributes to a better understanding of the impact that the digital paradigm is having on higher education. Moreover, the complex processes in both formal and informal learning are being transformed today [36]. One of their multiple manifestations would be the case of emojis, which are already beginning to be studied in the educational field [43,[83][84][85][86][87].
Nowadays, there is a growing demand for the need to be trained not only for life but for your entire life, to be updated, and to have more possibilities to occupy new job positions at the postgraduate level. This is the context in which, today, the mastery of ICTs is fundamental, of which these students are aware [88,89]. The diversity of groups within this group is also notable, since there are bachelor's degree graduates who immediately pursue a postgraduate degree, people who have a medium level of experience in the work environment, as well as people who have merged professional experience and a postgraduate program, so there is a diversity of ages [90][91][92][93][94]. This is also the case with profiles, for example, with postgraduate programs related to education. They are not necessarily graduates of careers such as pedagogy, educational sciences, preschool education, and elementary and high school; some people have a background in other disciplines and have decided to teach [95][96][97]. Its objective is to strengthen didactic and pedagogical issues, which is why there is diversity and richness in both age and training. In this heterogeneous context, however, we find that our study shows a great homogeneity in the use of emojis, which determines that their use is not very different between age and professional profiles.
About studies similar to ours, which allow us a comparison when making the documentary review of studies on the use of emojis at the postgraduate level, we only found the study of Gómez-Camacho and Gómez del Castillo [8], who analyzed the differential features of the conversations that take place on WhatsApp between Spanish students at the University of Seville. However, the objective they pursued differed greatly from ours since this study is oriented to analyze the conversations that are generated in that environment. They concluded that the digital norm in adult postgraduate students is characterized by a progressive approach to standard Spanish writing and is not related to an increase in misspellings in formal texts, as in previous studies. In our case, the focus of the work, although it coincides at the university educational level, was with graduate students from different Mexican universities, where their opinion has been noted concerning the interactions they establish concretely in WhatsApp groups with their peers. This has allowed us to quantitatively and qualitatively analyze their perceptions, points of view, and advantages and disadvantages in a general way of this new way of communication that has increased in people of different ages and the groups that are formed with friends, coworkers, and fellow students. There is, therefore, a great demand to investigate, from different perspectives, everything related to these new languages that have emerged in the digital paradigm [98][99][100][101].
As mentioned above, the culture considered is a key factor in the interpretation of the most commonly used emojis [63]. Thus, since this paper presents an exhaustive study for Mexican culture, it could be considered a new contribution to complete the vision of this subject in the different cultures of the world.

Conclusions
According to the results of this study, the frequency of use of emojis in WhatsApp amongst graduate students is increasing. Among the different uses (social interactions, expressing emotions, understanding messages, and writing styles), the highest percentages obtained are in the section of social interactions, highlighting that for the students, the most important thing about the use of emojis is to generate empathy and more enjoyable conversation and strengthen confidence. In this sense, in educational contexts and within learning models in mixed and online environments, emojis can be useful to strengthen social presence in the pedagogical designs themselves (creating an atmosphere of trust, a space for open communication, social cohesion, and group collaboration). It could be a matter of great interest for educational technologists in these innovative training frameworks.
The emojis that students use the most with their group mates are (i) the happy face, (ii) smiling, and (iii) the finger pointed up. It is important to point out that this is an interesting fact in these resources that accompany the processes of written communication in today's society through technological means since they determine that these languages present intercultural characteristics that are sometimes more direct than the use of spoken or written language.
According to the results, what stands out most about the emojis are their aspects related to the expression of emotions, feelings, and moods, saving time, a better understanding of the message, and the emphasis of some ideas. It is also stressed that the use of them reflects the personality of the person using them.
Emojis can confuse if the meaning is different for the sender and the receiver, which can cause misunderstanding as well as the deterioration of personal relationships. Furthermore, emojis consume valuable time and, occasionally, the attention is directed more towards the emojis than to the central message. Thus, excessive use of emojis reduces vocabulary and sometimes increases informal language. However, a significant percentage of students find no disadvantages in their employment.
The changes that have been generated in the communication processes (emoticons, emojis, stickers, customized avatars) and the strength that these have on the virtual learning environments in both informal and formal spaces has reached not only groups of family and friends but also colleagues and students. It allows us to recognize that communication is a fundamental resource for human beings, which are characterized by their social nature; this also shows the dynamic, dialectic, and ecosystemic elements that characterize the current communicative processes.
Regarding the main limitations of our study, we would like to indicate that the sample is smaller than we initially expected, but in the area of graduate studies, it is more difficult to achieve participation due to the academic and professional commitments within which most of these students work. Many are doing their master's thesis or doctoral dissertation and, at the same time, working in the educational field, in companies, and at the universities themselves. However, this work aims, in addition to the valuable data obtained, to determine the effectiveness of our instrument to collect the information sought. It serves us as a first study for other surveys that we will carry out later on in the international sphere. We are especially interested in offering joint results in the Latin American context, where there are no comparative studies in this regard.
We must also, as a limitation, base the results only on the answers given by the university graduates of Mexico. In future studies, it might be applicable to carry out an observation of actual usage. Nor have we carried out a triangulation of the data (for example, by using this questionnaire, observation, content analysis). Valuable data could also be obtained through research communities, such as "The Community of Inquiry (CoI)" (https://coi.athabascau.ca/). They would also give us information about the use of emojis in this area and how they can facilitate the speed of information communication and message exchange. This will be a work to be developed in future lines of research, in which the sample could also be extended to various countries in Latin America and at the international level. Another study that can be undertaken would be the comparison between the use of these new communicative languages among the population in general and in the university world in particular.
