Though current studies are limited by small sample sizes and brief follow-up durations, the observed enhancements in visual acuity, contrast sensitivity, and stereopsis across multiple studies signify that EMS has the potential to transform amblyopia treatment.

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":"2025-06-05","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}

To unite this research across disciplines and to allow progress in mechanistic understanding, we aimed to provide a definitive answer to whether there are different subtypes (factors) of visual hypersensitivity. In Study 1, we generated questions from a large qualitative dataset (n = 765), existing literatures, questionnaires, and iteratively from participant feedback. We found four theoretically coherent factors replicated across five cohorts (n’s = 349, 517, 349, 417, 797 and 1817). These factors were: brightness (e.g., sunlight), repeating patterns (e.g., stripes), strobing (e.g., flashing, screen motion), and intense visual environments (e.g., supermarkets, traffic). There was also a general factor. Based on this we produced a novel 20-item questionnaire (the Cardiff Hypersensitivity Scale, CHYPS), with good reliability (<strong>α</strong> > 0.8, ω > 0.8) and convergent validity (correlations with other visual scales r > 0.6).

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.

Additionally, we introduced conditions with and without competing stimuli (a black patch on the opposite side to the original white patch that is supposed to elicit pupil contraction) to investigate the role of visual competition in PLR modulation and explored the pupillary dark response (PDR) to assess whether attentional biases affect pupil dilation. 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.
