Yet, in closely coupled human-machine interactions, it is important to ensure that human attention and cognition remains sufficiently high to avoid accidents and to achieve a good performance. The aim of the present study was to examine whether hand-arm vibrations impact on cognitive processing. In two studies, we investigated the impact of constant or random vibration compared to a baseline condition without vibration on selective attention. In detail, we assessed overall performance (RT and error rates) and the congruency effect in a flanker task (Experiment 1) and a temporal flanker task (Experiment 2). In Experiment 2, we additionally explored experienced vibration comfort and discomfort, two constructs often considered in ergonomics. In both experiments hand-arm vibrations neither affected mean response times nor proportion of correct responses. Additionally, hand-arm vibrations did not modulate the congruency effect. Experiment 2 revealed that vibration comfort and discomfort seem to correlate with task-performance. We conclude that hand-arm vibrations in general do not impact on cognitive processing, but it seems important to consider which vibration is selected to achieve optimal performance depending on user experience.</p>","PeriodicalId":32728,"journal":{"name":"Journal of Cognition","volume":"9 1","pages":"18"},"PeriodicalIF":2.3,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12922676/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147272156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Challenging this view, the dual system model stipulates that non-symbolic comparisons rely on the ANS while symbolic comparisons rely on a discrete semantic system (DSS). In three experiments, the current study tests whether symbolic and non-symbolic magnitude comparisons rely on a common ANS or a DSS by examining the correlation between the size and distance effects in numerical magnitude comparison. We replicated previous studies, which used one-digit numbers 1 to 9, but also aimed to increase variance by using less familiar number ranges. Experiment 1 used a fixed-reference paradigm (reference = 55) with two-digit integers (11-99). Experiments 2 and 3 extended the design to decimals (0.01-0.98) with variable (Experiment 2) or fixed reference (Experiment 3). All experiments additionally included non-symbolic dot comparison in which the expected negative correlation between size and distance effect emerged. Across experiments, size and distance effects in less familiar number ranges were uncorrelated when presented in symbolic format, corroborating the idea that symbolic number comparison relies on a DSS. These findings were moderated by the observation of a significant correlation between size and distance effects in a subsample of participants who showed significant size and distance effects at the individual level.

Participants performed a psychological refractory period (PRP) experiment with a varying stimulus onset asynchrony (SOA), which is the time interval between the onsets of the stimuli for Task 1 (T1) and Task 2 (T2). Trials included task repetitions, where T2 was identical to T1, and task switches, where T2 differed from T1. T2 performance was worse with shorter SOAs than with longer SOAs and in switch trials than in repetition trials, indicating a PRP effect and switch costs. Notably, switch costs were not modulated by the SOA. However, SOA cannot precisely determine whether T1 and T2 are performed with or without temporal overlap in a given trial. To distinguish between these trials, we assessed the time interval between the T1 response and the onset of the T2 stimulus, known as the response-stimulus interval (RSI). The RSI acts as a proxy to temporally localize when T1 response selection is completed and the response-selection bottleneck is released, This novel trial-by-trial approach revealed that switch costs did not differ between trials with and without temporal overlap in task processing. Moreover, RSI was found to predicted T2 performance more accurately than SOA. Using RSI as a predictor of RT2 provides persuasive evidence that task selection and response selection rely on independent cognitive processes. Alternatively, both processes use shared central processing limitations, but temporal and/or strategic factors prevent these processes from overlapping in time and thereby interfering with each other.</p>","PeriodicalId":32728,"journal":{"name":"Journal of Cognition","volume":"9 1","pages":"13"},"PeriodicalIF":2.3,"publicationDate":"2026-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12879994/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146143919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surprisingly however, evidence for this has come only from studies employing free and serial recall, where the identity of an object is recalled, but not in cued recall, where one object feature is recalled when another one is cued. This is despite both tasks requiring binding features into an object in working memory (WM) - our brain's capacity-limited system for temporarily maintaining information for the purpose of achieving behavioral goals. The present study investigated this discrepancy across a series of four experiments. Contrary to the literature, and despite near-identical task settings, we found evidence in favor of a bimodal advantage across multiple experiments. Moreover, our results suggest that this advantage mainly arises from perceptual processes at encoding rather than from storage in an audiovisual fashion in WM. Finally, a primarily perceptually-based process, the bimodal advantage appears to be sensitive to the characteristics of the cue feature (i.e., its presentation modality). In sum, our results shed light on the mechanism of the bimodal advantage, now robustly detected in cued recall tasks, furthering our understanding of the relationship between perception and WM.

Previous research suggests that imitative response tendencies become modulated by the goals to which one's own and others' actions are individually or jointly directed. However, an open question is how different levels of goal representation (ranging from higher-level goals that specify joint or individual action outcomes to lower-level goals encoding own and others' movement features) interact and shape imitative congruency effects during social interactions. To address this gap, we conducted two online experiments, in which participants selected one of two action targets in turn with a virtual co-actor to achieve either individual or joint task goals. We manipulated imitative congruency between both task partners' task contributions regarding their individual action goals as well as their lower-level movement goals. Our results showed that participants' task performance was driven by imitative congruency between their own and their partner's individual action goals, which modulated effects of imitative congruency between their own and their partner's low-level movement goals. Interestingly, these imitation effects were found to be present regardless of instructing participants to work towards individual or joint task goals. While supporting goal-directed theories of imitation, our findings suggest that modulations of imitative response tendencies may stem from domain-general action planning and control processes that operate across social and non-social task settings, and that instructions to pursue joint rather than individual task goals exert only limited influence on imitative action tendencies in interactive task contexts.</p>","PeriodicalId":32728,"journal":{"name":"Journal of Cognition","volume":"9 1","pages":"10"},"PeriodicalIF":2.3,"publicationDate":"2026-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12785670/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145953279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
