In Experiment 1, the visual information used for face recognition was compared across four conditions that gradually reduced experimental control over the testing environment and stimulus properties. In Experiment 2, the association between face recognition abilities and information utilization was measured online and compared to lab-based results.

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.

Measuring the way that the computations underlying contrast processing depend on factors such as spatial and temporal frequency, age, clinical conditions, eccentricity, chromaticity and the presence of other stimuli has been a focus of vision science for over a century. One of the most productive experimental approaches in this field has been the use of the ‘steady-state visually-evoked potential’ (SSVEP): a technique where contrast modulating inputs are ‘frequency tagged’ (presented at well-defined frequencies and phases) and the electrical signals that they generate in the brain are analyzed in the temporal frequency domain. SSVEPs have several advantages over conventional measures of visually-evoked responses: they have relatively unambiguous ouput measures, a high signal to noise ratio (SNR), and they allow us to analyze interactions between stimulus components using a convenient mathematical framework. Here we describe how SSVEPs have been used to study visual contrast over the past 70 years. Because our thinking about SSVEPs is well-described by simple mathematical models, we embed code that illustrates key steps in the modelling and analysis. This paper can therefore be used both as a review of the use of SSVEP in measuring human contrast processing, and as an interactive learning aid.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"231 ","pages":"Article 108614"},"PeriodicalIF":1.5,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143899099","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}

Substantial asymmetry between S+ and S− was found in pedestal discrimination thresholds, but not in S+ and S− perceptual scales: perceived S cone contrast was nearly linear with S cone contrast for both polarities. To reconcile perceptual scales and thresholds, a model is proposed in which the noise in the S cone pathway is assumed to be proportional to the square root of stimulus contrast.

Related to this, the visual crowding effect is weaker in letter reading than in recognizing symbols in a string. A previous study reported that crowding reduction was observed exclusively in horizontal strings by participants with extensive reading experience in horizontal text strings. In the present study, we examined letter identification performance across various string orientations among Japanese readers with extensive experience reading both vertically and horizontally oriented texts. Through three experiments, we observed crowding reduction among Japanese readers in vertical test strings. Additionally, the observed crowding reduction was not robust when reading strings along unfamiliar orientations, such as diagonal orientations. These findings suggest that reading experience with specific text orientations adaptively shapes the spatial properties of letter-specific detection units. However, our results also indicate that reading experience has limited influence. For example, crowding reduction was not as robust for Japanese letters as it was for alphabet letters, showing that the influence of reading experience on crowding reduction depends on letter type, whereas letter type in previous reading does not matter. Furthermore, when the strings aligned with the zone where stronger crowding occurs, irrespective of letter type, crowding reduction was not robust, even for alphabet. These results imply that the reading experience could affect only a specific part of letter identification, which is likely important for alphabet identification in higher-level processing.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"231 ","pages":"Article 108598"},"PeriodicalIF":1.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887177","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, pattern onsets produce large and reliable evoked potentials for chromatic stimuli, while pattern reversal responses are considerably weaker. These differences likely arise in part from the transient and sustained nature of the achromatic and chromatic pathways, respectively; contrast adaption of the sustained, chromatic pathways may also contribute to these observations, as time-averaged contrast is higher for pattern reversals than for pattern onsets. Evidence suggests chromatic pathways may also be tuned for orientation similar to achromatic pathways. Changing orientations may stimulate additional neural populations and reduce contrast adaptation’s effect on the evoked potential. We recorded responses to chromatic and achromatic patterns using both onsets and reversals, with and without alternating orientation. As a control, we included a “reversing” onset condition with a 180-degree spatial shift between presentations. Results revealed that responses binned over 6 s did not exhibit adaptation over 60 s. Chromatic onsets with alternating orientation or phase resulted in larger amplitudes and shorter latencies. Both orientation and phase changes increased chromatic onset responses for the L-M axis, but VEP amplitudes were smaller for alternating phases than for alternating orientations on the S-axis. One possible explanation is that in addition to recruiting different orientation-selective neurons, alternating phase or orientation produces motion responses, which are more prominent in L-M pathways than S pathways. Alternating the phases or orientations of the patterns likely increases the evoked response by recruiting additional neuron populations but at the cost of pathway specificity.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"231 ","pages":"Article 108609"},"PeriodicalIF":1.5,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143881536","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}

A review of this literature leads to the conclusion that the distortions and discomfort can have their basis in an excitability of the visual cortex.

The above conclusion is reached as follows. Images from nature, despite their heterogeneity, have in common certain statistical features that enable them to be encoded efficiently by the human visual system. Certain images that have an un-natural spatial and chromatic structure (including text) can be uncomfortable to look at. They can give rise to a large cortical haemodynamic response, consistent with indications from computational neurology that they are processed inefficiently. There are large differences between people in susceptibility to discomfort from images. These differences reflect differences in medical history.
