Substantial research has been undertaken on language processing in silence, with several studies indicating the impact of noise on language processing in non-emergencies. However, it remains unclear about the neural mechanisms involved in language processing during emergencies, especially the role of the language network (LN) and the default mode network (DMN) in such contexts. In this study, we adopted functional near-infrared spectroscopy (fNIRS) to investigate brain activities of 60 participants who were performing language processing tasks in simulated high-emergency and low-emergency scenarios. Compared to the resting state, the reading task demonstrated reduced activation in bilateral superior and middle frontal gyri (SFG/MFG), components of the DMN, alongside enhanced activation in Broca's area, left temporal lobe and left inferior parietal lobule (IPL) – key LN regions. Furthermore, the activity of the left MFG was positively correlated with the level of stress experienced by participants during the task. Additionally, a positive correlation was identified between language processing performance and activation of the left MFG, exclusively in the participants exposed to high-emergency scenarios. These results support the view that language processing during emergency relies on both the LN and DMN. The current study deepens our understanding of the neural mechanisms that underlie language processing in complex, real-life emergency scenarios.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"213 ","pages":"Article 109152"},"PeriodicalIF":2.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143881992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The debate persists on whether language and thought are distinct entities or if language is deeply embedded in individual cognitive processes. This study employs adjective cues combined with a mental imagery size judgment task as an experimental paradigm, utilizing neurophysiological techniques to preliminarily explore the role of adjectives in size judgment tasks and their underlying neurophysiological mechanisms. Findings reveal that performance is best when adjectives are congruent with the size of the object, with EEG microstate results indicating strong activity in Class A, related to language networks under this condition. Additionally, when adjectives conflict with object size, the discovery of the Ni component suggests that individuals monitor and inhibit the conflict between adjectives and object size, leading to decreased task performance in this condition. Moreover, when object size is ambiguous, individuals' size judgments do not benefit significantly from clear adjective cues. Event-related potentials and EEG microstate results suggest that under this condition, top-down cognitive resources are recruited more extensively. In conclusion, language plays a more crucial role in simpler judgment tasks; as tasks become more complex, judgment processes engage a greater number of distributed brain regions to collaborate, while the language system remains active. This study provides initial cognitive neuroscience evidence for understanding the relationship between language and simple forms of thought, offering preliminary insights for future investigations into the connection between language and thought.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"213 ","pages":"Article 109151"},"PeriodicalIF":2.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We then present results and model fits from three experiments using a recently developed multiple cue paradigm where several attention shifts with different associated reward values are competing. We show that participants were surprisingly efficient at selecting both when the number of cues and the number of possible reward values were increased. Only when we manipulated reward contingencies and knowledge of these, did the participants show suboptimal performance. The new Generalized Biased Competition account can also explain failures of executive control exemplified by goal neglect where instructions fail to influence behavior despite being retrievable. Finally, we argue that our model may provide a unified understanding of intentions, routines, and habits.

Such memory representations are thought to rely on memory integration mechanisms. The present study used multivariate pattern analysis (MVPA) of electroencephalographic (EEG) data to elucidate the temporal dynamics of integrative encoding memory processes. Memory integration was investigated with the associative inference task. Participants learned overlapping paired associates, AB and BC pairs, comprising a word and a picture (a face or a bird) and were later tested on the AC inferred associations. MVPA was used to measure the online reactivation of previously learned AB memories while encoding overlapping but new BC events. Reliable AB reactivation was observed approximately 1500 ms after the onset of the BC event. Participants (n = 29) were divided into two groups according to their AC performance: high and low memory integration. Interestingly, while both groups showed comparable levels of AB reactivation, the reactivation effects were associated with different behavioral consequences. For participants in the high memory-integration group, reactivation was predictive of later AC performance, suggesting that an integrated ABC representation was formed during BC learning. Conversely, for participants in the low memory-integration group, the reactivation of AB was negatively correlated with BC performance, indicating that reactivation of overlapping memories impaired new learning. The present study extends previous literature by revealing the temporal dynamics of the integrative encoding mechanisms and by providing an account of inter-individual differences in the capacity to integrate memories across distinct episodes.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"212 ","pages":"Article 109148"},"PeriodicalIF":2.0,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143828576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preliminary evidence suggests that neural predictors of vection can be identified through event-related potentials (ERPs) and that these markers may correlate with vection intensity. The current study examined age-related differences in neurocortical activity during the early stages of sensory processing of vection-inducing stimuli. Twenty-two younger (age range: 20–35 years) and 25 older adults (age range: 65–83) observed optokinetic stimuli in two blocks, a short (∼3s) presentation block and a long (35s) presentation block. In both types of blocks, the optokinetic stimuli varied in motion coherence (coherent vs. non-coherent motion). During the short presentation block, EEG was used to measure neural activity in the form of ERPs time-locked to the onset of visual motion, whereas subjective ratings of vection intensity, duration, and onset latency were collected during the long presentation block. Vection was significantly stronger following coherent vs. non-coherent motion for both age groups. ERP analyses revealed differences between coherent and non-coherent motion at parietal-occipital electrodes around 100–150 ms (P1) and 150–230 ms (P2), with greater area under the curve (AUC) during non-coherent vs. coherent motion. Neither vection ratings nor ERPs showed significant age differences for coherent visual motion; however, age differences in ERPs were observed during the processing of non-coherent visual motion. These findings indicate that the subjective experience of vection and the neurophysiological mechanisms underlying visual processing preceding vection remain relatively stable with age.
