Background/Objectives: Speech perception typically takes place against a background of other speech or noise. The present study investigates the effectiveness of segregating speech streams within a competing speech signal, examining whether cues such as pitch, which typically denote a difference in talker, behave in the same way as cues such as speaking rate, which typically do not denote the presence of a new talker. Methods: Native English speakers listened to English target speech within English two-talker babble of a similar or different pitch and/or a similar or different speaking rate to identify whether mismatched properties between target speech and masker babble improve speech segregation. Additionally, Dutch and French masker babble was tested to identify whether an unknown language masker improves speech segregation capacity and whether the rhythm patterns of the unknown language modulate the improvement. Results: Results indicated that a difference in pitch or speaking rate between target and masker improved speech segregation, but when both pitch and speaking rate differed, only a difference in pitch improved speech segregation. Results also indicated improved speech segregation for an unknown language masker, with little to no role of rhythm pattern of the unknown language. Conclusions: This study increases the understanding of speech perception in a noisy ecologically valid context and suggests that there is a link between a cue’s potential to denote a new speaker and its ability to aid in speech segregation during competing speech perception.

Background/Objectives: Accurate assessment of speech intelligibility is necessary for individuals with motor speech disorders. Transcription or scaled rating methods by naïve listeners are the most reliable tasks for these purposes; however, they are often resource-intensive and time-consuming within clinical contexts. Automatic speech recognition (ASR) systems, which transcribe speech into text, have been increasingly utilized for assessing speech intelligibility. This study investigates the feasibility of using an open-source ASR system to assess speech intelligibility in Hebrew and English speakers with Down syndrome (DS). Methods: Recordings from 65 Hebrew- and English-speaking participants were included: 33 speakers with DS and 32 typically developing (TD) peers. Speech samples (words, sentences) were transcribed using Whisper (OpenAI) and by naïve listeners. The proportion of agreement between ASR transcriptions and those of naïve listeners was compared across speaker groups (TD, DS) and languages (Hebrew, English) for word-level data. Further comparisons for Hebrew speakers were conducted across speaker groups and stimuli (words, sentences). Results: The strength of the correlation between listener and ASR transcription scores varied across languages, and was higher for English (r = 0.98) than for Hebrew (r = 0.81) for speakers with DS. A higher proportion of listener–ASR agreement was demonstrated for TD speakers, as compared to those with DS (0.94 vs. 0.74, respectively), and for English, in comparison to Hebrew speakers (0.91 for English DS speakers vs. 0.74 for Hebrew DS speakers). Listener–ASR agreement for single words was consistently higher than for sentences among Hebrew speakers. Speakers’ intelligibility influenced word-level agreement among Hebrew- but not English-speaking participants with DS. Conclusions: ASR performance for English closely approximated that of naïve listeners, suggesting potential near-future clinical applicability within single-word intelligibility assessment. In contrast, a lower proportion of agreement between human listeners and ASR for Hebrew speech indicates that broader clinical implementation may require further training of ASR models in this language.

Background/Objectives: Sunk cost bias—continuing failing endeavours due to prior investments—is among the most studied decision-making biases. Despite decades of vignette-based research, these measures lack systematic psychometric validation. We examined whether widely-used sunk cost scenarios reliably measure the same psychological construct. Methods: Across two experiments (N = 395), we tested established sunk cost vignettes, including classic scenarios from Arkes and Blumer (1985). English-speaking participants from Prolific Academic completed vignettes alongside cognitive reflection and social desirability measures. We assessed internal consistency and intercorrelations between scenarios. Results: Internal consistency was consistently poor (ω = 0.14–0.57) with weak intercorrelations between scenarios. Even highly similar vignettes correlated only moderately. External validity was problematic, showing inconsistent relationships with cognitive reflection and social desirability across vignettes. Conclusions: These measurement failures have critical implications for neuroimaging research, where unreliable behavioural measures may be mistaken for genuine neural differences. The field needs systematic categorization of scenarios to identify which vignettes engage specific psychological processes and neural circuits, enabling more targeted theoretical development.

This study examines the relationship between learning environments and learning outcomes in acquiring Korean as a language target. We compare two learner groups residing in the United States: English-speaking learners of Korean in foreign language contexts versus Korean heritage speakers. Both groups share English as their dominant language and receive similar tertiary-level instruction, yet differ in their language-learning profiles. We measure two groups’ comprehension behaviour involving Korean subject−predicate honorific agreement, focusing on two conditions manifesting a mismatch between the honorifiable status of a subject and the realisation of the honorific suffix in a predicate. Results from the acceptability judgement task revealed that (1) both learner groups rated the ungrammatical condition as more acceptable than native speakers did, (2) Korean heritage speakers rated the ungrammatical condition significantly lower than English-speaking learners, and (3) overall proficiency in Korean modulated learners’ evaluations of the ungrammatical condition in opposite directions between the groups. No between-group difference was found in the infelicitous-yet-grammatical condition. Results from reaction time measurement further showed that Korean heritage speakers responded considerably faster than English-speaking learners of Korean. These results underscore the critical role of broad usage experience—whether through home language exposure for heritage language speakers or formal instruction for foreign language learners—in shaping non-dominant language activities.

Self-forgiveness is identified as a contributor to psychological wellbeing and may serve as a mechanism through which religiosity supports mental health. There is a dearth of research on wellbeing and the role of self-forgiveness in the English-speaking Caribbean. This preliminary study explored the relationship between religiosity, self-forgiveness, and wellbeing among persons with serious mental illness (SMI), a population largely overlooked in this context. A convenience sample of 362 out-patients receiving care in Trinidad and Tobago completed self-reported measures of self-forgiveness, the Religious Commitment Inventory, and Havard’s Flourishing Measure. Inferential statistics examined group differences in religiosity and wellbeing, and predictive relationships among key variables. Among persons with SMI, higher religiosity was significantly associated with greater wellbeing (p < 0.0001). Additionally, there was greater wellbeing among those who reported a propensity to self-forgive compared to those who did not (p < 0.0001). Self-forgiveness explained a significant part of the relationship between religiosity and wellbeing. Furthermore, among the non-highly religious, self-forgiveness was also significantly associated with greater wellbeing (p < 0.001). Our findings suggest that self-forgiveness may mediate the link between religiosity and wellbeing, highlighting its potential as a therapeutic coping mechanism for individuals with serious mental illness. This study adds to the growing literature on religious coping in mental health and underscores the need for further research to clarify the mediating role of self-forgiveness. Full article

Background/Objectives: Research regarding the relationship between insomnia symptoms and self-regulated eating behaviors in Hispanic populations is limited, particularly that pertaining to emerging adulthood (18–25 years old) and the potential role of cultural factors. The present study explored the association between insomnia symptoms and self-regulated eating behaviors in a Hispanic emerging adult sample, as well as the role of acculturative stress. Methods: Participants who identified as Hispanic between the ages of 18–25 years old and were English-speaking completed an online survey assessing insomnia symptoms, self-regulated eating behavior, and acculturative stress. Results: In a multiple regression analysis, insomnia symptoms emerged as a significant predictor of self-regulated eating behavior such that Hispanic individuals with increased insomnia symptoms were more likely to report low self-regulated eating behavior. Furthermore, it was found that acculturative stress partially mediated the association between insomnia symptoms and self-regulated eating behavior. Conclusions: Insomnia symptoms are a risk for problematic eating behaviors in Hispanic emerging adults. Identifying other early risk factors, including culturally unique risks like acculturative stress, may be important for the development of tailored early intervention efforts to reduce problematic eating patterns.

In 2021, the National Centre for Religious Studies in New Zealand published the new religious education curriculum for Catholic schools in Aotearoa New Zealand. While in many ways, very like other religious education curricula, from its naming in Māori before English, Tō Tātou Whakapono Our Faith shines a light on the role of culture and language in the transmission and expression of faith. This paper is written in two parts. Part 1 of this paper provides an examination of the key curriculum documents and website to find that Tō Tātou Whakapono Our Faith is unique in three ways. First, it enjoys a level of security in the dominant presence of Catholics in the Catholic school, guaranteed by the Integration Act of 1975. Second, it offers flexibility in approach, necessary for a curriculum with national status, and finally, it demonstrates an extraordinary commitment to the inclusion of Māori culture and language. Part 2 of this paper takes up the inclusion of Māori culture and language to offer a response to the call that Māori need to be allowed to develop a theology from within their own culture and language. It proposes that the introduction of a new hermeneutical lens in the study of scripture, one that would replicate the practice of the Bible authors who drew freely on their own experience and language to speak of God, could provide a simple but effective way of developing such a theology. It is in Part 2 that the significance of the subtitle of this paper will become apparent. Full article

Background/Objectives: This study assessed Knowledge and Practices related to Food Safety (KPFS) among nutrition services employees in hospitals across the Al-Ahsa Governorate, Kingdom of Saudi Arabia. The objective was to evaluate the staff’s understanding of key food safety principles, including foodborne illness prevention, food handling, personal hygiene, and food storage and preparation practices. Methods: A descriptive survey method was used, and data were collected using an electronic questionnaire, which was either self-administered by the participants or completed with the assistance of the researcher in cases involving employees who did not speak Arabic or English. This study included 302 staff members involved in the preparation, service, and supervision of food provided to hospital patients. Results: The results indicated a high level of knowledge among nutrition services employees regarding food safety principles, critical temperature control, cross-contamination prevention, and proper hygiene practices. The employees also demonstrated a strong commitment to personal hygiene behaviors, such as handwashing, wearing appropriate clothing, and avoiding unsafe practices. Additionally, a high degree of knowledge and understanding was found regarding food storage procedures and contamination prevention. The study also highlighted a very high level of awareness concerning the cleaning and sterilization of equipment, tools, and food storage surfaces, as well as maintaining a clean and healthy environment. These findings emphasize the importance of continuous training in enhancing food safety knowledge among nutrition services employees. Conclusions: It is recommended that all employees, regardless of education level, experience, or role, participate regularly in food safety training programs to sustain and improve food safety practices within hospital environments.

Social media applications (SMAs) stand at the forefront of emerging technologies in language education due to their transformative potential to enhance English speaking skills. Unlike traditional tools, SMAs leverage features like real-time communication, multimedia integration, and global connectivity, fostering authentic, meaningful interactions in socially engaging environments. Although learning management systems (LMSs) such as Brightspace have been predominantly used to conduct English language learning activities, including peer feedback, SMAs like Facebook offer unique affordances that may further promote student engagement and confidence. Developing public speaking skills is critical for effective communication in English language education; however, many students struggle with self-efficacy, speaking anxiety, and providing meaningful feedback to peers. Given the potential benefits of SMAs, this study explored their comparative impact on three dimensions of English language learning: English public speaking self-efficacy, peer feedback self-efficacy, and English speaking performance. This quasi-experimental study used a pretest–posttest design with undergraduate students (n = 15) at a large Midwestern university in the United States. Independent sample t-tests were conducted to compare outcomes between the Facebook and Brightspace groups. The results revealed that both SMAs and LMSs were equally effective platforms for peer feedback activities, with no significant differences found between groups across the three targeted areas of learning.

We investigated how participants’ humor styles impact their sarcasm use. English-speaking participants (N = 179) completed online self-report measures of humor styles and sarcasm use. We conducted linear regressions to test whether their humor style scores could predict their sarcasm use scores. Participants with higher affiliative humor scores reported a greater tendency to use sarcasm in general and to use face-saving sarcasm to protect the social images of the speaker and addressee. People use face-saving sarcasm to enhance their relationships, to tease others, and to self-deprecate. Surprisingly, participants who scored high on aggressive humor reported using face-saving sarcasm often. We suspect this occurred because the aggressive humor and the face-saving scales contain conceptually similar items. Participants with high aggressive humor scores also reported frequently using sarcasm to diffuse frustration. Participants who scored high on self-defeating humor reported often using both face-saving sarcasm and sarcasm to diffuse embarrassment. Given that face-saving sarcasm use was uniquely predicted by affiliative humor, aggressive humor, and self-defeating humor scores, we suggest that face-saving sarcasm use has utility for people with a wide range of humor styles. Our findings highlight how an individual’s humor style shapes their flexible use of sarcasm in interpersonal relationships. Full article

Generative artificial intelligence is reshaping how people interact with digital technologies, emphasizing the need to develop effective skills for engaging with it. In this context, prompt engineering has emerged as a critical skill for optimizing AI-generated outputs. However, research on how higher education students interact with these technologies remains limited, particularly in non-English-speaking contexts. This exploratory study examines how 102 higher education students in Chile formulated prompts in Spanish and how their techniques influenced the responses generated by ChatGPT (free version 3.5). A quantitative analysis was conducted to assess the relationship between prompt techniques and response quality. Two emergent prompt engineering strategies were identified: the Guide Contextualization Strategy and the Specific Purpose Strategy. The Guide Contextualization Strategy focused on providing explicit contextual information to guide ChatGPT’s responses, aligning with few-shot prompting, while the Specific Purpose Strategy emphasized defining the request’s purpose, aligning with structured objective formulation strategies. The regression analysis indicated that the Guide Contextualization Strategy had a greater impact on response quality, reinforcing the importance of contextual information in effective interactions with large language models. As an exploratory study, these findings provide preliminary evidence on prompt engineering strategies in Spanish, a relatively unexplored area in artificial intelligence education research. Based on these results, a methodological framework is proposed, encompassing four key dimensions: grammatical skills; prompt strategies; response from the large language model; and evaluation of response quality. This framework lays the groundwork for future artificial intelligence digital literacy interventions, fostering critical and effective engagement with generative artificial intelligence while also highlighting the need for further research to validate and expand these initial insights.

Currently, there are no validated instruments in Italian specifically designed to assess mental illness stigma or prejudice. Moreover, implicit measures, while insightful, are often resource-intensive and impractical for large-scale population studies of Italian speakers. The present study investigated the validity of the Italian version of the Prejudice towards People with Mental Illness scale (PPMI-IT) in measuring biases toward individuals with mental health issues. The original instrument by Kenny et al. was translated from English into Italian and vice versa. A sample of 455 Italian-speaking participants (65% female; M_age = 33.39; SD = 13.21) was utilized to conduct a confirmatory factor analysis, confirming a four-factor structure (fear/avoidance, malevolence, authoritarianism, unpredictability). Factor loadings indicated that each dimension was well represented, supporting the construct validity of the scale. Model fit indices, including chi-square (χ² = 782.54, df = 296.00, χ²/df = 2.64), RMSEA (0.06, 90% CI: 0.060–0.07), CFI (0.93), TLI (0.91), and SRMR (0.06), suggest an excellent model fit. Furthermore, the analysis of correlations and the heterotrait/monotrait (HTMT) ratio provides evidence supporting the discriminant validity of the PPMI scale compared with social desirability. These findings confirm that the PPMI scale is a valid and reliable tool for assessing biases toward individuals with mental health issues, making it suitable for academic research, clinical interventions, and public policy contexts.

Current research predominantly involves human subjects to evaluate AI creativity. In this explorative study, we questioned the validity of this practice and examined how creator–assessor (dis)similarity—namely to what extent the creator and the assessor were alike—along two dimensions of culture (Western and English-speaking vs. Eastern and Chinese-speaking) and agency (human vs. AI) influences the assessment of creativity. We first asked four types of subjects to create stories, including Eastern participants (university students from China), Eastern AI (Kimi from China), Western participants (university students from The Netherlands), and Western AI (ChatGPT 3.5 from the US). Both Eastern participants and AI created stories in Chinese, which were then translated into English, while both Western participants and AI created stories in English, which were then translated into Chinese. A subset of these stories (2 creative and 2 uncreative per creator type, in total 16 stories) was then randomly selected as assessment materials. Adopting a within-subject design, we then asked new subjects from the same four types (n = 120, 30 per type) to assess these stories on creativity, originality, and appropriateness. The results confirmed that similarities in both dimensions of culture and agency influence the assessment of originality and appropriateness. As for the agency dimension, human assessors preferred human-created stories for originality, while AI assessors showed no preference. Conversely, AI assessors rated AI-generated stories higher in appropriateness, whereas human assessors showed no preference. Culturally, both Eastern and Western assessors favored Eastern-created stories in originality. And as for appropriateness, the assessors always preferred stories from the creators with the same cultural backgrounds. The present study is significant in attempting to ask an often-overlooked question and provides the first empirical evidence to underscore the need for more discussion on using humans to judge AI agents’ creativity or the other way around.

This study examines the psychological mechanisms through which BTS’s perceived star attributes—expertise, authenticity, likability, and similarity—influence fan loyalty within fandom-driven tourism. Anchored in activity theory and content theory of motivation, the proposed model identifies psychological need fulfillment and emotional satisfaction as sequential mediators linking celebrity perception to loyalty behaviors. Data were obtained from 916 BTS fans across six English-speaking countries via a structured online survey. To test the hypothesized relationships, Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed. Results demonstrate that perceived star attributes significantly enhance psychological need fulfillment, which subsequently predicts emotional satisfaction and loyalty. Additionally, the attributes exert direct effects on emotional satisfaction, supporting both reflective and intuitive engagement pathways. All hypothesized paths were statistically significant, and the model exhibited strong overall fit (SRMR = 0.039; NFI = 0.875). Theoretically, this study advances loyalty research by foregrounding the roles of symbolic consumption, emotional resonance, and identity-based alignment in global fandom contexts. Practically, the findings offer insights for tourism marketers, destination planners, and entertainment brands seeking to design emotionally immersive, narrative-rich tourism experiences. Recommendations are provided for developing BTS-themed content aligned with fans’ identity motivations to foster sustained emotional engagement and destination loyalty. Full article

In this paper we describe the processes and challenges involved in the design, implementation, and assessment of a small-scale intervention in four primary schools in Ghana’s Central Region that aimed to enhance learners’ mother tongue and bilingual literacy practices whilst at the same time strengthening their sense of cultural identity. Within the framework of Educational Design Research (EDR), this paper describes the steps that were involved in the development process, from context analysis to the design of a locally developed Fante–English bilingual storybook, as well as the formative evaluation of this prototype. This paper shows how to translate contextual findings into a final product, while sharing with the reader important findings for each phase in the process. Formative evaluation in the form of a teacher workshop, surveys, and classroom observations was used. Results showed that, in the opinion of teachers, Fante–English bilingual books can promote learners’ cultural identity, self-awareness, and a sense of prestige when they speak the language. Not only do the books preserve the Fante language and culture, but they show learners that Fante is just as important as English. A second round of formative evaluation showed that additional teacher manual and training could benefit the outcome of the bilingual method. Full article
