We investigated this developmental trajectory using a specialized set of digit stimuli (Pelli fonts) tailored for measuring foveal crowding. We measured foveal crowding in preschoolers, school-age typically developing children, and school-age children with developmental dyslexia, as well as in a group of adults. The results show that foveal crowding decreases with age, reaching adult-like levels around 8 years among preschoolers and typically developing children. Furthermore, dyslexic children exhibited heightened foveal crowding compared to their typical peers by approximately the same amount, regardless of age and reading level. Notably, preschoolers exhibited the most pronounced foveal crowding effects with considerable individual variability: some displayed crowding similar to that of older typical children and adults, while others exhibited similar or even higher levels of crowding compared to dyslexic children. This large variability suggests that foveal crowding may have the potential to serve as an early indicator for identifying developmental dyslexia, a possibility that warrants further longitudinal investigation.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"237 ","pages":"Article 108681"},"PeriodicalIF":1.4,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144933176","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}

However, so far studies have confounded retinal eccentricity with distance from the center of a display, and the observed effects may thus have been driven by what is known as the central fixation bias, which is the preference for items near the center of a display rather than the center of the retina. This study aimed to dissociate the central selection bias from the central fixation bias, and to uncover its time course. In two experiments, participants were instructed to make a single eye movement to one of two simultaneously presented singletons. The singletons were always presented at the same distance from the center of the display (thus controlling for the central fixation bias) but their eccentricity relative to the initial fixation point was varied (thus allowing for a central selection bias to operate). When the two singletons were displayed at different eccentricities, participants preferred selecting the nearest item. This central selection bias occurred rapidly and transiently, peaking around 230 ms and lasting until approximately 320 ms after display onset. Together, these results suggest that retinal eccentricity is a major factor when multiple objects compete for selection.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"237 ","pages":"Article 108682"},"PeriodicalIF":1.4,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144916853","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}

Behavioral and neuroimaging studies suggest that high-level scene information modulates activity in object-selective brain areas through top-down mechanisms, yet the underlying mechanism of this process remains unclear. Here, we introduce a biologically inspired context-based computational model (CBM) that integrates scene context into object recognition via an explicit feedback mechanism. CBM consists of two distinct pathways: Object_CNN, which processes localized object features, and Place_CNN, which extracts global scene information to modulate object processing. We compare CBM to a standard feedforward model, AlexNet, in a multiclass object recognition task under varying levels of visual degradation and occlusion. CBM significantly outperformed a standard feedforward model (AlexNet), demonstrating the effectiveness of structured contextual feedback in resolving ambiguous or degraded visual input. However, behavioral experiments revealed that while humans also benefited from congruent context — particularly at high occlusion levels — the effect was modest. Human recognition remained relatively robust even without contextual support, suggesting that mechanisms such as global shape processing and pattern completion, likely mediated by local recurrent processes, play a dominant role in resolving occluded input. These findings highlight the potential of contextual feedback for enhancing model performance, while also underscoring key differences between human and models. Our results point toward the need for models that combine context-sensitive feedback with object-intrinsic local recurrent processes to more closely approximate the flexible and resilient strategies of human perception.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"237 ","pages":"Article 108679"},"PeriodicalIF":1.4,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144920316","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}

To investigate the magnocellular pathway’s role in metric spatial vision, we employed an adaptation paradigm. Exposure to a 60 Hz flickering disc array (subjectively invisible) induced a systematic compression in the perceived distance between subsequently presented dot pairs. This compression was strongest when adaptation preferentially modulated low spatial frequency channels, consistent with the properties of transient channels tuned to low spatial and high temporal frequencies. Crucially, this compression was attenuated when the adaptor consisted of two cyan lattices rotating on a magenta background near isoluminance, as confirmed by a global motion direction discrimination task. The same pattern emerged when test dots were isoluminant with the background, ruling out test-adaptor similarity as a critical factor. Finally, an isoluminant red-green adaptor flickering on a yellow background induced compression at 3 Hz, but not at 60 Hz. This dissociation aligns with the known properties of magnocellular neurons, which are insesitive to high temporal frequency isoluminant red-green modulation, but can respond to slow isoluminant red-green modulations.

However, the behaviour of regressive saccades, which move the eyes in the opposite direction, remains less explored. This study delves into the landing positions of regressive saccades, emphasizing the distinction between intra-word and inter-word regressions, across diverse languages. Using data from the MECO L1 project, which includes eye-tracking data from 589 participants across 13 languages, we scrutinize the precise landing positions of regressions vis-à-vis forward saccades. Our analysis shows a robust effect of launch distance on landing positions for progressive saccades, with undershoots increasing as launch distance grows and overshoots with shorter launch distances. In contrast, regressive inter-word saccades show only minimal variation in landing positions, typically landing near the centre of the target word regardless of launch distance or word length. Intra-word regressions, however, display a pattern similar to progressive saccades, where the landing position is influenced by launch distance, tending to overshoot the optimal viewing position as the launch site moves away from the word’s end. This pattern is consistent across all languages. These findings support the notion of cross-linguistic universality in oculomotor control mechanisms during reading, particularly the precision of regressive saccades. They align with the spatial coding hypothesis, suggesting that precise spatial memory of word positions guides regressive saccades.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"236 ","pages":"Article 108678"},"PeriodicalIF":1.4,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887495","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}

However, it is unclear whether motor activation is subject to this influence. The response priming paradigm is a suitable tool in cognitive psychology to investigate motor preactivations in general. Here, two experiments investigate the behavioral priming effects of upside-down presented biological movements on static targets in different SOA-steps. We use two stimuli for biological movements: a dynamic point-light walker (Experiment 1) and a face with a dynamic gaze (Experiment 2). Both stimuli are compared to their upright versions. While with upright biological movements, we replicate strong PCEs in both experiments, an upside-down PLW led to significantly weaker PCEs, suggesting an attenuation of priming effects through inversion. Interestingly, a scrambled-dot condition led to sustained PCEs, suggesting possible preserved local motion trajectories. As to gaze primes, both an upright and an upside-down version produced equally strong PCEs with a decline at a longer SOA. Motor activation elicited by gaze movement direction is sustained and independent from orientation. Our findings show that inversion can affect motor activation in biological motion processing.
