In Chinese, intransitive verbs can take direct objects in certain constructions, and transitive verbs can also be used without objects. These characteristics have long sparked debates about whether verbs can be divided into intransitive and transitive verbs in Chinese. Using E-Prime software (3.0 version) and functional magnetic resonance imaging (fMRI) technology, we investigated the behavioral responses and neural activities of native speakers when processing Chinese intransitive and transitive verbs. Behavioral data showed that the accuracy rate for Chinese intransitive verbs was significantly higher than that for transitive verbs, while the reaction time was significantly shorter. fMRI data revealed that compared with Chinese intransitive verbs, transitive verbs elicited significantly stronger activation in brain regions such as the bilateral angular gyri (BA39), left supramarginal gyrus (BA40), and left inferior frontal gyrus (BA44). The bilateral angular gyri and left supramarginal gyrus may be associated with more intricate argument semantic representation of the Chinese transitive verb, while the left inferior frontal gyrus may reflect their more complex syntactic structure representation. The above experimental results indicate that processing Chinese transitive verbs requires greater cognitive effort and involves more complex neural activities compared to intransitive verbs, which demonstrates that verbs in Chinese should be subdivided into intransitive and transitive verbs.

This study investigates whether and, if so, how cognates facilitate lexical–semantic processing during early bilingual development. Additionally, we examine the interaction between the cognate facilitation effect (CFE) and bilingual experience factors, such as language proficiency, exposure, and age. We investigated language backgrounds and recorded event-related potentials during a semantic priming task in Dutch–German bilingual children. Most participants were Dutch-dominant, characterized by higher exposure and proficiency in Dutch. We compared the N400 response to target words preceded by semantically related cognate versus non-cognate primes. We found a reduced N400 effect (indexing cognate facilitation) only in the non-dominant language (nDL; German). Individual difference analyses further revealed that higher proficiency of nDL and increasing age attenuated the CFE. In contrast, higher cumulative exposure was associated with an amplified CFE. These findings suggest that cross-linguistic activation in lexical–semantic processing may benefit younger children with either lower proficiency or higher exposure to their non-dominant language during language processing. Together, the study offers direct neural evidence for bilingual cognate facilitation effects and highlights the importance of investigating interactions with external factors in early bilingualism. Future longitudinal research should examine whether cognate reliance serves as a temporary scaffolding mechanism for the acquisition of the non-dominant language. Full article

Human interaction with manipulable objects relies heavily on the ability to perceive and execute grasping actions, yet it remains unclear whether the semantics of these actions are processed without conscious awareness. While previous work has identified bottom-up influences on grasp recognition, direct evidence for subliminal semantic processing of grasping actions is limited. Grounded in embodied cognition theory—which posits overlapping neural mechanisms for action language and action execution—the present study examined whether grasp-related verbs can elicit subliminal priming effects on grasping-action recognition. Using a masked priming paradigm, participants classified objects requiring either precision or power grasps while subliminal Chinese action verbs served as primes. Behavioral measures revealed faster responses for semantically congruent cue–target pairs. ERP analyses further demonstrated congruency effects in the N400 and P600 components, reflecting semantic integration and conflict monitoring, as well as modulation of the P300 associated with action-related evaluation. Both grasp types showed evidence of unconscious semantic processing, though precision- and power-grasping actions produced distinct neural patterns. These findings provide direct experimental support for subthreshold semantic activation of grasping actions and confirm the viewpoint of action-language-embodied processing. The study advances the theoretical understanding of unconscious-action semantics and offers a framework for investigating how manipulative-action meaning is accessed below the threshold of awareness.

With the rapid growth in the scale and complexity of software systems, automated vulnerability detection has become increasingly important. Although Large Language Models (LLMs) demonstrate strong code comprehension capabilities, their abilities in vulnerability detection are still limited by issues such as hallucinations, high fine-tuning costs, and difficulties in effectively leveraging fine-grained historical vulnerability patterns and domain knowledge. To address these challenges, we propose Retrieval-Augmented Semantic Mapping for Vulnerability Detection (RASM-Vul), a retrieval-augmented framework that enhances LLM detection capability through multi-perspective semantic mapping. The core of our approach is the construction of a comprehensive knowledge base composed of vulnerability–fix pairs and structured knowledge. We leverage multi-view (e.g., code, AST, knowledge) similarity retrieval to accurately match the most relevant vulnerability patterns with repair examples for the code under analysis. Our designed Weighted Reciprocal Ranking Fusion (WRRF) algorithm adaptively integrates contributions from different retrieval channels according to the problem type, significantly improving the relevance and accuracy of retrieval. Experiments show that RASM-Vul achieves an F1-score of 66.79%, outperforming existing baselines on the PrimeVul paired dataset. Our study demonstrates that knowledge-enhanced semantic mapping and retrieval can improve the robustness and reliability of automated vulnerability detection. Full article

This study used event-related potentials (ERPs) to examine how deaf individuals process ambiguous morphemes during Chinese compound word recognition in a masked priming lexical decision paradigm. Ambiguous morphemes were classified as balanced or biased, and two experiments employed a 3 × 2 within-subject design. Each morpheme’s two meanings served as both primes and targets. The independent variables were prime type (meaning1 vs. meaning2 vs. unrelated) and target type (meaning1 vs. meaning2), with meaning1 being the dominant meaning and meaning2 being the subordinate meaning for biased morphemes. In the N250 (sublexical processing), balanced morphemes showed a main effect of prime type: any orthographically similar prime elicited priming. In the N400 (semantic processing), an interaction of prime and target type emerged, with only contextually congruent meanings activated. For biased morphemes, interactions were observed across N250 and N400 stages. The dominant meaning was consistently activated: when the target was dominant, both meanings showed priming; when the target was subordinate, only the subordinate meaning produced priming. These results reveal a dissociation in how deaf readers process ambiguous morphemes: balanced morphemes rely on contextual information, whereas biased morphemes are influenced by meaning frequency. The findings provide novel insights into the temporal dynamics of morpheme-based lexical access in deaf Chinese readers, with implications for reading and vocabulary instruction. Full article

Previous research has shown that the perceptual span in Chinese reading extends three characters to the right of the fixation point. However, little is known regarding the types of preview information that can be extracted from such a distant position; namely, the character at the N + 3 position. Using the parafoveal priming paradigm combined with eye-tracking technology, we manipulated the preview type and preview duration to examine whether Chinese readers could extract orthographic, phonological, and semantic information from the character at the N + 3 position across three experiments. Experiment 1 revealed an orthographic preview cost: orthographically similar previews delayed the target character recognition compared to unrelated previews. Experiment 2 showed no evidence of phonological preview effects. Experiment 3 demonstrated a semantic preview benefit: semantically related previews significantly facilitated the target character recognition relative to unrelated previews. Taken together, these findings indicate that Chinese readers are able to extract orthographic and semantic, but not phonological, information from a distant parafoveal position. Full article

If one believes that $2+2=4$, then one also believes that either $2+2=4$ or 971 is a cousin prime number. This follows from doxastic logics based on standard Kripke relational semantics, which validate disjunction introduction for belief. However, this principle does not hold in topic-sensitive semantics. An agent who lacks the concept of a ‘cousin prime number’ may be unable to entertain, and thus unable to believe, any proposition involving that concept. I argue that while disjunction introduction may fail for belief—and for other epistemic states that presuppose belief—it does hold for certain states that do not require belief. In this paper, I focus on the notion of commitment to the truth. Drawing on the concept of logical grounding, I propose formal semantics that preserve the requirement of topic-grasping, but weaken it in a way that allows for a more standard treatment of disjunction.

The present study employed immersive virtual reality (iVR) technology to create a multimodal enriched learning environment and investigated the effects of pre-training on sleep-dependent consolidation of novel word learning. Native Chinese speakers were randomly assigned to either a pre-training group or a control group. Both groups learned two sets of novel words, one on Day 1 and the other on Day 2. All participants completed an explicit recognition task and an implicit semantic priming task on Day 2. The results reveal the sleep-dependent consolidation effects in the implicit measures, with enhanced semantic priming observed for words learned on the previous day following a sleep interval. Moreover, the pre-training yielded additional benefits for sleep-dependent consolidation, as evidenced by the improved sleep-dependent consolidation effects of the pre-training group as compared with the control group. However, no sleep-dependent consolidation and pre-training effects were observed in the explicit recognition task. These findings suggested that pre-training serves as an effective strategy to reduce cognitive load and facilitate novel word learning in iVR environments. This study provides new evidence for the pre-training principle of cognitive load theory from the perspective of sleep-dependent consolidation. Full article

It is theoretically accepted that Chinese two-character words (2C-words) are processed both holistically and according to their constituent characters. Given the evidence on readers’ sensitivities to the syntactic relationships between the constituent characters, however, this general view might not fully explain the 2C-word processing mechanism. As an important category of 2C-words, verb–object constructions (VOCs) exhibit significant heterogeneity in splittability, the degree of syntactic phrasalization through the insertion of other characters between the constituent characters. To examine skilled readers’ VOC processing under the influences of splittability and whether the constituent characters are bound or free characters (character type), two experiments were conducted on a cohort of college students, who were Chinese native speakers, using the lexical decision task in a repetition priming paradigm. The prime stimuli (primer type) comprised three conditions: (a) the targets themselves, (b) the targets’ transposed non-words, and (c) non-linguistic baseline symbols ‘※※’. The primers’ two constituents were presented simultaneously and sequentially in Experiments 1 and 2, respectively. A significant interaction was revealed across both experiments between splittability and character type in the participants’ performance. The main effect was significant for primer type in the participants’ performance in Experiment 1; in Experiment 2, however, the interaction was significant both between primer type and splittability in the participants’ performance and between primer type and character type in their reaction times. In addition to confirming the general view, skilled readers might inevitably experience syntactic and semantic combinations of the constituent characters in their processing of VOCs. Full article

Objectives: The objective of this study was to assess the potential existence of shared semantics between linguistic (e.g., reading a sentence) and numerical information (e.g., performing an arithmetic operation). Methods: To evaluate this proposal, we devised a paradigm with blocks of two trials. In the first trial, participants were presented with sentences containing verbs that conveyed either an increase (e.g., “to give”) or a decrease (e.g., “to take away”). In the subsequent trial, participants were required to perform additions (e.g., 61 + 1) and subtractions (e.g., 52 − 4). We hypothesized that addition and subtraction would exhibit shared semantic processing with sentences denoting increase and decrease, respectively, resulting in cross-domain effects. Results: Participants exhibited enhanced speed and accuracy in addition problem-solving when preceded by increase sentences, whereas subtractions were solved with higher accuracy when preceded by decrease sentences. Moreover, these effects were found to be subject to modulation by the complexity of the numerical operation. Conclusions: The findings of this study support the hypothesis that there is a shared semantic processing between language and mathematics. Full article

Two experiments were used to test the hypothesis that studying has a greater impact on learning when the information being studied is currently less accessible in memory. This hypothesis aligns with well-established findings like the spacing effect, but it is inconsistent with other evidence. Prior research has not directly tested the causal relationship between accessibility and learning. Two experiments were used to manipulate memory accessibility using semantic priming. The results indicated that differences in accessibility had no impact on learning. Retrieval difficulty and retrieval success also failed to influence learning. It is speculated that changes in accessibility that are specifically due to forgetting, rather than changes in accessibility per se, may have a causal impact on learning efficiency. Full article

Background/Objectives: Individuals with chronic agrammatic aphasia demonstrate real-time sentence processing difficulties at the lexical and structural levels. Research using time-sensitive measures, such as priming and eye-tracking, have associated these difficulties with temporal delays in accessing semantic representations that are needed in real time during sentence structure building. In this study, we examined the real-time processing effort linked to sentence processing in individuals with aphasia and neurotypical, age-matched control participants as measured through pupil reactivity (i.e., pupillometry). Specifically, we investigated whether a semantically biased lexical cue (i.e., adjective) influences the processing effort while listening to complex noncanonical sentences. Methods: In this eye-tracking while listening study (within-subjects design), participants listened to sentences that either contained biased or unbiased adjectives (e.g., venomous snake vs. voracious snake) while viewing four images, three related to nouns in the sentence and one unrelated, but a plausible match for the unbiased adjective. Pupillary responses were collected every 17 ms throughout the entire sentence. Results: While age-matched controls demonstrated increased pupil response throughout the course of the sentence, individuals with aphasia showed a plateau in pupil response early on in the sentence. Nevertheless, both controls and individuals with aphasia demonstrated reduced processing effort in the biased adjective condition. Conclusions: Individuals with aphasia are sensitive to lexical–semantic cues despite impairments in real-time lexical activation during sentence processing. Full article

Words are the basic units of language and vital for comprehending the language system. Lexical processing research has always focused on either conceptual or affective word meaning. Previous studies have indirectly compared the conceptual and affective meanings of words. This study used emotion-laden words, a special type of dual-meaning word, to directly compare the time course of processing conceptual and affective word meanings. Free association was applied in Experiment 1 to investigate the time course of conceptual and affective meanings in dual-meaning words. The results showed that conceptual-meaning processing was superior to affective-meaning processing. In Experiment 2, the semantic/affective priming paradigm was used to directly compare the time courses of processing conceptual and affective word meanings by manipulating stimulus onset asynchrony (SOA) in different ways. The results showed that semantic and affective priming effects could be obtained under short SOA conditions, with no differences between them. Consistent with Experiment 1, only the semantic priming effect was observed in the long SOA condition. These findings suggest that the conceptual and affective meanings of words have different time courses. The conceptual meaning of words includes automatic and controlled processing, whereas the affective meaning mainly involves automatic processing. Full article

Aim: The aim was to evaluate the effect of body actions on learning process, particularly semantic memory capabilities in drug-naïve children with attention deficit hyperactivity disorder (ADHD). Method: Thirty children had to listen to a story which was repeated three times in a row and then a fourth time five minutes later. After each listen, the child was asked what she/he remembered from the story. The whole sample was split randomly into three subgroups of equal IQ (mean 102.2 ± 12.7), age (mean age 8 ± 0.6 years), sex (ratio female to male 1:5) and severity of ADHD symptoms (34.2 ± 7.4); a G1 “Freeze” subgroup, which implied listening to the story while sitting on a chair without moving; a G2 “Minimal” subgroup, which implied listening to the story while sitting on a chair but free movement was allowed; a G3 “Prescribed movement” subgroup, which implied listening to the story standing up, while copying the experimenter movements that mimicked the actions told in the story. Results: Although our sample was limited in size, interestingly, children in the G3 subgroup showed the highest short-term semantic memory retention compared to G1. In all subgroups, repetition allowed an increase in performance. Conclusions: Our exploratory findings stress the positive role of movement in children with ADHD to increase semantic memorization. Hyperactivity may counteract the deficit of memorization related to attention impairment in children with ADHD. Our results may encourage parents or teachers to allow children with ADHD to move around during short-term memory-retention tasks. Full article

Information that comes from the environment reaches the brain-and-body system via sensory inputs that can operate outside of conscious awareness and influence decision processes in different ways. Specifically, decision-making processes can be influenced by various forms of implicit bias derived from individual-related factors (e.g., individual differences in decision-making style) and/or stimulus-related information, such as visual input. However, the relationship between these subjective and objective factors of decision making has not been investigated previously in professionals with varying seniority. This study explored the relationship between decision-making style and cognitive bias resistance in professionals compared with a group of newcomers in organisations. A visual “picture–picture” semantic priming task was proposed to the participants. The task was based on primes and probes’ category membership (animals vs. objects), and after an animal prime stimulus presentation, the probe can be either five objects (incongruent condition) or five objects and an animal (congruent condition). Behavioural (i.e., accuracy—ACC, and reaction times—RTs) and self-report data (through the General Decision-Making Scale administration) were collected. RTs represent an indirect measure of the workload and cognitive effort required by the task, as they represent the time it takes the nervous system to receive and integrate incoming sensory information, inducing the body to react. For both groups, the same level of ACC in both conditions and higher RTs in the incongruent condition were found. Interestingly, for the group of professionals, the GDMS-dependent decision-making style negatively correlates with ACC and positively correlates with RTs in the congruent condition. These findings suggest that, under the incongruent decision condition, the resistance to cognitive bias requires the same level of cognitive effort, regardless of seniority. However, with advancing seniority, in the group of professionals, it has been demonstrated that a dependent decision-making style is associated with lower resistance to cognitive bias, especially in conditions that require simpler decisions. Whether this result depends on age or work experience needs to be disentangled from future studies. Full article
