The participants consisted of a total of 107 students, 55 (51.4%) were males and 52 (48.6%) were female, aged between 10 and 12 years. A total of 41 children (38.3%) attending the fifth grade and 66 children (61.7%) the sixth grade were randomly selected. The data collection instrument, Self-concept of Susan Harter validated for the Portuguese population was used and it was proceeded to a descriptive and inferential statistics data analysis to confront the mean levels of self-concept, global self-esteem and academic performance.Results: As an influence of hours of weekly practice, we found statistically significant differences in terms of academic performance, that is, as the student practices more hours of physical exercise, there is a tendency for the student to obtain better academic results.Conclusions: Apparently, the practice of extracurricular sport activities by students promotes a significant evolution in the formation of self-concept and academic performance, as well as suggesting a positive evolutionary trend in the formation of self-esteem of students who practice the several extracurricular sports.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"16 1","pages":"320-332"},"PeriodicalIF":2.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87030629","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 used gaze-contingent masking and windowing to control foveal and extrafoveal inputs while observers (N = 35) classified the emotion (anger, disgust, fear, surprise, sadness) on face images. Emotion classification performance was substantially reduced by the absence of extrafoveal information but was unaffected by the absence of foveal information. Gaze decoding showed that fixation patterns discriminated viewed emotion categories regardless of whether either foveal or extrafoveal information was absent or both were present, more so when observers provided correct responses. Although fixations clustered around the eyes, nose, and upper mouth, emotion-specific biases in fixation densities aligned with regions previously identified as emotion diagnostic, and, for trials with incorrect responses, with locations informative of the most confused emotion. Even without extrafoveal information, necessitating top-down guidance of gaze, fixations were biased to these same emotion-informative regions. Yet, the spatiotemporal sequencing of fixations differed in the absence versus presence of extrafoveal information. Fixation patterns also predicted stimulus presentation conditions, most evident in differences due to the absence versus presence of extrafoveal rather than foveal inputs. Thus, where one looks on a face impacts the ability to determine its emotional expression, not only via the higher resolving power of foveal vision but also by the extrafoveal extraction of task-relevant information and guidance of gaze, and possibly also via the interplay between foveal and extrafoveal vision that underpins presaccadic attention.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 8","pages":"4"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12227034/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, an analysis of response trajectories revealed a repulsive bias during response execution, irrespective of the condition. These surprising findings prompted us to attempt a replication. We confirmed the main findings of Chen and Bae. However, we also demonstrated that the overall direction and magnitude of the bias are relatively stable for a given observer, regardless of the condition. Furthermore, we found that already the very first moment in the response trajectory differed between conditions, showing a predominantly attractive bias for trials that ended with attraction.

As these advances continue to shape the study of retinotopic organization, it is crucial to revisit the methodologies used to generate and model these maps. In this review, we examine empirical and theoretical work aimed at reconstructing and modeling visual field maps in the human visual cortex. Specifically, we discuss how empirical retinotopic mapping has facilitated the development of theoretical and computational models of retinotopy and, in turn, how these models have enhanced our understanding of the retinotopic organization of the human visual cortex.

This experience is thought to enable the formation of a view-invariant representation by learning which features are critical to identify faces across views. Discovering these critical features and the type of experience that is needed to uncover them is challenging. A recent study revealed a subset of facial features that are critical for human face recognition. Furthermore, face-trained deep convolutional neural networks (DCNNs) were sensitive to these facial features. These findings enable us now to ask what type of face experience is required for the network to become sensitive to these human-like critical features, and whether it is associated with the formation of a view-invariant representation and face classification performance. To that end, we systematically manipulated the number of within-identity and between-identity face images during training and examined its effect on the network performance on face classification, view-invariant representation, and sensitivity to human-like critical facial features. Results show that increasing the number of images per identity, as well as the number of identities were both required for the simultaneous development of a view-invariant representation, sensitivity to human-like critical features, and successful identity classification. The concurrent emergence of sensitivity to critical features, view invariance and classification performance through experience implies that they depend on similar features. Overall, we show how systematic manipulation of the training diet of DCNNs can shed light on the role of experience in the generation of human-like representations.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 8","pages":"2"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12227020/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although extensively studied in vision across tasks such as numerosity, orientation discrimination, and attractiveness, its effect on visual time perception remains partially unexplored. Here, we investigated serial dependence in visual temporal perception, using two common tasks: temporal interval duration discrimination and temporal reproduction. In the discrimination task, participants judged whether the second of three visual stimuli was longer or shorter than the third, with the first stimulus being irrelevant, to induce serial dependence on the second stimulus. In the temporal reproduction task, participants were asked to reproduce an interval presented between two visual stimuli by pressing a button. Given the debate concerning the origin of the serial dependence effect and possible relation with memory processing, we also investigated the relationship between serial dependence and working memory capacity using a Corsi test. Our results showed that serial dependence does occur in visual time perception, but no relationship was found between the effect of the two tasks and memory retention capacity. The lack of correlation between serial dependence effects suggests that different processes may be involved in serial dependence across the two types of tasks.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 8","pages":"7"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12236629/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144555561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the dynamics of temporal integration requires understanding the influence of an ongoing temporal context. Toward this goal, we developed a novel paradigm of temporal integration where two halves of a Kanizsa square are integrated together (seen as a full square) or segregated (not seen as a full square) as a function of a temporal gap between them. The two halves are embedded within a preceding and succeeding context of rotating Kanizsa discs leading up to and trailing away from them. We wanted to investigate whether integration is subject to frames of interest or whether the dynamics of the context influence form-part integration. Through three experiments, we manipulated the nature of the rotation: (a) the context being temporally correlated or random in Experiment 1, (b) the variance of the temporally correlated context in Experiment 2, and (c) the mean of the temporally correlated context in Experiment 3. Our results showed that the sensitivity of seeing an integrated square was better when the context aided anticipation of the target frames, the effect being selective at different inter-stimulus intervals depending on the properties of the context. We interpret these results in light of a probabilistic view of temporal windows of integration. Our results provide evidence for an inherent adaptiveness in the extent or window of temporal integration. The results also reinforce the general account of extended temporal processing and iterative updating and inform rough timescales of context effects on this process.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 8","pages":"11"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12255175/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on how sensory eye dominance varies across visual space. Although some characteristics of variations in sensory eye dominance across visual space have been described before, results so far are largely conflicting. Here I argue that this conflict is caused by the fact that different studies used different methods to assess sensory eye dominance, combined with using a wide range of eccentricities. To systematically and continuously describe sensory eye dominance across the visual field, I used a novel method-tracking Continuous Flash Suppression-in which a visual target presented to a single eye moved across the horizontal meridian while being in constant competition with a dynamic mask presented to the other eye. Eye dominance across the visual field could be described and quantified using three factors: (1) a generic preference for the nasal visual field in combination with (2) an observer-dependent general bias for using the left, right, or neither eye. On top of these, some observers had (3) idiosyncratic biases in local sensory eye dominance. I argue that, while idiosynchratic local biases within an observer probably stem from optical, retinal, or cortical imbalances, the observed nasal advantage is functional: it allows to bias the interocular competition to fixated, partly occluded distant objects of interest.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 8","pages":"1"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12227019/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Responses evoked by blur or disparity cues elicited a reduced accommodative response, as indicated by peak velocity and final amplitude, compared to responses from blur and disparity cues.

The illusion of perceptual filling-in occurs when eye gaze is kept still: visual boundary perception may fail, causing adjacent visual features to remarkably merge into one uniform visual surface. Microsaccades-small, involuntary eye movements during gaze fixation-counteract perceptual filling-in, but the mechanisms underlying this process are not well-understood. We investigated whether microsaccade efficacy for preventing filling-in depends on two boundary properties, namely, color contrast and retinal eccentricity (distance from gaze center). Twenty-one human participants (male and female) fixated on a point until they experienced filling-in between two isoluminant colored surfaces. We found that increased color contrast independently extends the duration before filling-in, but does not alter the impact of individual microsaccades. Conversely, lower eccentricity delayed filling-in only by increasing microsaccade efficacy. We propose that microsaccades facilitate stable boundary perception via a transient retinal motion signal that scales with eccentricity but is invariant to boundary contrast. These results shed light on how incessant eye movements integrate with ongoing stimulus processing to stabilize perceptual detail, with implications for visual rehabilitation and the optimization of visual presentations in virtual and augmented reality environments.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 8","pages":"8"},"PeriodicalIF":2.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12248979/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144576781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
