SoJA is ubiquitous in human-human interaction. Therefore, it is both interesting as well as relevant to understand the factors that affect the formation of SoJA both in human-human and in human-robot interaction. On the one hand, previous work suggests that sensorimotor cues may be the main determinant of “lower-level” implicit SoJA in human-human joint action. On the other hand, recent work shows that contextual factors, such as perceived intentionality, can impact the formation of implicit SoJA with a humanoid robot. In the current study, we aimed to investigate, using behavioral and electroencephalography (EEG) measures, whether endowing a humanoid robot with a precisely human sensorimotor pattern would be sufficient to elicit SoJA with the robot, even without manipulating the perceived intentionality of the robot. Participants completed a joint task with another human, and with a robot that was controlled by another human, thus endowing the robot with a precisely human sensorimotor repertoire. Importantly, participants completed two sessions with this controlled robot. In one session, they were (factually) told that the robot was controlled by another human. In another session, they were told that the robot was pre-programmed. We expected that participants may attribute less intentionality to the robot they believed was pre-programmed. In either session, participants' perception regarding the robot's intentionality was not explicitly manipulated. Interval estimates for self- and other-generated actions were used to estimate SoJA. In addition, we also measured participants' readiness potential (RP) for self- and partner actions, and their N100 responses for self- and partner-generated sensory outcomes in the task. The results show that temporal estimates, and ERPs, did not differ between self- and partner-generated action-outcome conditions, in both human-human and human-robot sessions. Thus, these results suggest that endowing a humanoid robot with a human sensorimotor pattern may be sufficient to elicit SoJA in joint action with the robot, regardless of the intentionality attributed to the robot. Furthermore, an exploratory spectral analysis of movement-related beta activity suggested that people may nevertheless disengage earlier from the joint action when interacting with a robot partner, as compared to a human partner. Together, our results contribute to understanding the mechanisms that underlie the emergence of SoJA in joint action, as well as the extent to which artificial agents, such as humanoid robots, can be integrated into our teamwork as “full” interaction partners.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"223 ","pages":"Article 109372"},"PeriodicalIF":2.0,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146015896","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}

Post-stroke aphasic patients, in the post-acute phase and presenting with naming deficits, were assigned to one of two training conditions. The experimental group (EG) viewed videos of everyday gestures (i.e., pouring water, cutting carrots) from a first-person perspective, enhancing motor resonance, while the active control group (AC) viewed the same gestures from a third-person perspective. During video playback, the action was named by a female voice and the patient had to repeat it after video completion. The training was administered three times per week for four weeks. Naming abilities, along with other language and quality of life measures, were assessed pre- and post-intervention. Bayesian analysis of the primary outcome - percentage of rehabilitated items - yielded a Bayes factor BF₊₀ = 2.86, providing anecdotal-to-moderate evidence in favour of the first-person perspective group.

In this exploratory story, 16 individuals with CVI (mean age = 19.56 years ± 5.59 SD; mean verbal IQ = 94.85 ± 21.84) and 19 control participants (mean age = 21.37 years ± 5.21 SD; mean verbal IQ = 123.79 ± 12.59) completed the Star Cancellation Test (SCT). Gaze behavior was also recorded using wearable eye tracking (Tobii Pro Glasses 3; 100 Hz sampling rate) during naturalistic and standardized administration of the assessment. Controlling for age and verbal IQ level, we found that while test accuracy was not significantly lower in CVI participants, they took significantly longer to complete the task compared to controls. CVI participants also tended to spend more time verifying their work and had lower cancellation efficiency (a composite performance index incorporating accuracy and completion time). Regarding gaze metrics, CVI subjects had longer total fixation durations and higher fixation counts, as well as greater total saccade amplitudes (scan path length) and saccade counts. However, group differences were not significant when comparing normalized gaze metrics (i.e., average fixation duration and average saccade amplitude). The observed differences in behavioral performance and gaze metrics in CVI are consistent with a profile of less efficient and more effortful visual scanning and search. The use of standardized assessments combined with wearable eye tracking can provide further insight into the nature of visuospatial processing dysfunctions in this population.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"223 ","pages":"Article 109374"},"PeriodicalIF":2.0,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045983","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}

This article surveys current empirical research on aphantasia, focusing on five recently published comparative neurophysiological studies and how they mesh with four hypotheses proposed to account for reports of absence of mental imagery. These hypotheses explain such reports in terms of (i) a discrepancy in the use of concepts, (ii) a failure of introspection, (iii) a deficit in access to imagistic representations, and (iv) an absence of imagistic representations. The article concludes that these studies reveal neural differences between aphantasics and other individuals that allow us to reject the first two hypotheses and to consolidate the latter two as plausible explanations of aphantasia, with the final hypothesis emerging in a comparatively stronger position to provide a general account. The nature of the neural differences between these groups and how to understand them, however, remain far from clear, and the resolution of this issue presupposes the resolution of an ongoing debate between two neural models of mental imagery.</p>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":" ","pages":"109431"},"PeriodicalIF":2.0,"publicationDate":"2026-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147390746","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}

Thirty participants listened with closed eyes to four blocks of music, differing in their familiarity and relaxation potential and spanning a range of genres. In response to probes sent throughout listening, participants indicated whether or not they had been experiencing visual imagery and, if they had, whether the experienced visual imagery had been spontaneous or deliberate. Cluster permutation analyses on the time-frequency decomposed EEG data revealed alpha power suppression during visual imagery that was more reliable during spontaneous than deliberate imagery. Further, while theta and delta bands did not discriminate the presence or absence of the visual imagery experience or its intentionality subtypes, we observed that gamma power suppression in fronto-central areas was present during visual imagery experiences. Our results extend prior findings of a role of posterior alpha suppression in visual imagery to show its reliability in music-evoked spontaneous imagery specifically.

Currently, there are very few behavioural tasks measuring mental imagery, hence we used the mental comparisons task (MCT – Suggate, 2024) in which participants mentally compare a visual, auditory, or tactile property of stimuli in the physical absence of those objects. Using an online pre-registered study, we tested performance on the MCT for participants who have aphantasia (<em>n</em> = 48) versus those without (<em>n</em> = 95). In addition to the MCT and VVIQ, measures included the Plymouth Sensory Imagery Questionnaire, and questions on how they solved the MCT task. Consistent with other work, there appeared to be small non-significant correlations between self-report and behavioural measures. Aphantasics as a group appeared generally slower, but <em>more</em> accurate, on the MCT. Correcting for speed-accuracy trade-offs via balanced integration scores revealed that aphantasics had an advantage on tactile stimuli. In summary, findings support the idea that aphantasic participants have preserved performance generally, with better tactile mental processing.

The task required participants to infer the meaning of new words by extracting and integrating semantic cues from different sentences in a self-paced reading paradigm. The results showed that patients displayed difficulties to learn the meaning of new words from the context of the sentences (Exp. 1), which was reflected as more errors and null responses compared to controls, as well as increased reading times in conditions where meaning had to be integrated. Besides, we explored to which degree these learning differences could be attributed to working memory (WM) deficits. In Exp. 2 we ruled out this hypothesis, showing that semantic word learning was still impaired when reducing WM load. As a control condition, we also reported that these deficits remained even though patients had no impairment accessing synonyms or semantically related words of real words. These results strongly suggest a semantic learning impairment despite apparently preserved semantic processing abilities in HD patients.

Moreover, they exhibited enhanced amplitudes of P2 and LPP to negative stimuli, whereas no group differences were observed for the early N1 component.

Since mental health is closely tied to interoception, we examined whether interoceptive processing mediates the relationship between imagery ability and mental health. We assessed self-reported imagery vividness (VVIQ), subjective interoceptive accuracy and attention, alexithymia, anxiety, and depression in individuals with aphantasia (n = 153, VVIQ = 16–32) and typical imagers (n = 680, VVIQ = 33–80).

The results revealed that individuals with weak imagery (hypophantasia) showed greater alexithymia and worse mental health than those with almost no imagery (core aphantasia), with higher VVIQ predicting poorer outcomes within the aphantasia range. The opposite pattern emerged in typical imagers, where higher VVIQ predicted lower alexithymia and better mental health. Structural equation modeling revealed that these relationships were mediated by alexithymia and the ratio of subjective interoceptive accuracy to attention, with lower ratios (indicating effortful but unsuccessful interoceptive processing) associated with worse outcomes.
