In turn, CNNs are now widely used as a framework for studying human vision. The organizational similarity between the layers of CNNs and cortical regions along the visual pathway has been shown in studies using human fMRI data, such that early visual areas’ activities are better predicted by the first layers of CNNs while their last layers better predict the response of higher-level visual areas. However, there is a lack of agreement on how well CNN features can predict fMRI responses, particularly in the presence of fMRI noise, which can result in varying brain responses to the repetitions of the same image. Additionally, the utility of these predicted responses to previously unseen images as synthetic fMRI data has not yet been explored. Here we use the BOLD5000 dataset and the AlexNet architecture initialized with the model weights pre-trained on ImageNet to show that features extracted by CNNs can g enerate highly accurate synthetic fMRI responses to images. We demonstrate that synthetic fMRI responses show higher correlations with repetitions of real responses than the real responses themselves, surpassing the quality of real data in the presence of noise. Moreover, we train a decoder with synthetic fMRI data to classify real fMRI data for unseen images and even unseen object categories. Our decoding experiments revealed that the synthetic data outperformed real data, particularly due to the ability to generate larger synthetic datasets. Our findings showcase the high quality of generated synthetic fMRI responses to images based on CNN features, exhibiting both similarities to real data and practical utility in empirical applications.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"234 ","pages":"Article 108641"},"PeriodicalIF":1.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144330411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We extended a previous model, so that it performs a feature-based search of an image for a target. We show that induced grouping effects are the result of a connection strategy that links together target pairs in a visual search task combined with a selection strategy that tends to place a selection signal at locations close to the target pair features. These strategies interact because the connection strategy that links target pairs also sometimes links inducing elements, thereby influencing the selection signal location.

The spatiotemporal position of the target’s local motion was probed by a flashing dot that appeared within the range of ± 66.7 ms from the direction change. Observers had to report the perceived local motion using a motion vector matching method. The results show that the deviation of the perceived flow from the physical ground truth increased when the probe was presented near the direction changes. The pattern of errors averaged across multiple trials could be described by a Gaussian temporal smoothing of the local motion vectors, with a window size spanning about 120 ms. The results are consistent with previous reports of the sluggish temporal response of visual motion processing revealed by artificial stimuli and different tasks. However, a detailed examination of the response of each trial of our data indicated that the observers did not report a gradual transition from pre-change to post-change vectors but reported either of the two directions in a bimodal fashion with gradually changing response rates over time. This suggests that even though the motion processing may be sluggish, human observers correctly recognize a sudden direction change as a sudden event, not as a gradual transition.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"234 ","pages":"Article 108629"},"PeriodicalIF":1.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children aged 5–10 years categorised backwards-masked scenes presented at very brief durations. We drew inferences about the <em>processing speed</em> with which each age group extracted category-diagnostic information by varying presentation durations, and the <em>quality of information</em> extracted by varying the level they were prompted to make their judgments (superordinate-level indicative of coarse global information, basic-level indicative of more detailed information). Children across all ages demonstrated a remarkably sophisticated ability to extract scene gist, with 5–6-year-old children performing above chance for scenes presented for as little as 32 ms for both superordinate and basic-level judgements. Categorisation performance also became more efficient with age. Overall, our novel findings indicate that young children possess an impressive ability to process a scene’s gist, which is followed by a protracted development towards expertise across middle childhood.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"233 ","pages":"Article 108620"},"PeriodicalIF":1.5,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144072058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrary to our hypothesis, we did not observe a significant pseudoneglect effect, as pupil constriction was not consistently greater for left-sided stimuli. We found clear evidence for contraction anisocoria, whereby ipsilateral stimuli produce stronger constrictions than contralateral stimuli, thus highlighting the need to account for this physiological effect in future studies. Regarding PDR, we did not find significant attentional modulation or evidence of dilation anisocoria as pupil dilation amplitudes were similar across both hemifields.

It therefore has been suggested that the difference in modality is an important but not necessarily dominant factor for beat synchronization. However, doubts exist in favoring auditory dominance, as comparing continuously varying visual stimuli with discrete auditory stimuli is considered unfair. Here, based on a periodically contracting ring for which the spatial displacement continuously varied with a constant acceleration, we devised an equivalent in the auditory domain: an amplitude-modulated sound whose amplitude continuously varied with an acceleration of the same magnitude.
