We asked whether providing response feedback could change the serial dependence effect on the following trial. Twenty-one participants completed a task in which they adjusted an on-screen pointer to reproduce the orientation of a briefly-presented Gabor stimulus. They received feedback about the accuracy of their response that either reflected their actual accuracy or was random. We found significant positive biases to the stimulus and response only when the participant had received positive (\"correct!\") feedback on that trial. When the inducer response had been incorrect, the effect was significant only to the response itself and not to the stimulus.

Lowering intraocular pressure (IOP) remains the primary approach for managing glaucoma but IOP alone does not explain all glaucoma risks. Orthogonal approaches such as large-scale genetic screening, combined with studies of animal models have been instrumental in identifying genes and molecular pathways involved in glaucoma pathogenesis. Cell type dependent vulnerability among RGCs can reveal genetic basis for specific visual deficits.

Instead, studies show a surprising amount of detail is retained for each scene image allowing them to be distinguished from highly similar in-category distractors. The gist trace for images can be relatively easily captured through both computational and behavioural techniques, but capturing detail is much harder. While detail can be broadly estimated at the categorical level (e.g. man-made scenes more complex than natural), there is a lack of both ground-truth detail data at the sample level and a way to operationalise it for measurement purposes. Here through three different studies, we investigate whether the perceptual complexity of scenes can serve as a suitable analogue for the detail present in a scene, and hence whether we can use complexity to determine the relationship between scene detail and visual long term memory for scenes. First we examine this relationship directly using the VISCHEMA datasets, to determine whether the perceived complexity of a scene interacts with memorability, finding a significant positive correlation between complexity and memory, in contrast to the hypothesised U-shaped relation often proposed in the literature. In the second study we model complexity via artificial means, and find that even predicted measures of complexity still correlate with the overall ground-truth memorability of a scene, indicating that complexity and memorability cannot be easily disentangled. Finally, we investigate how cognitive load impacts the influence of scene complexity on image memorability. Together, findings indicate complexity and memorability do vary non-linearly, but generally it is limited to the extremes of the image complexity ranges. The effect of complexity on memory closely mirrors previous findings that detail enhances memory, and suggests that complexity is a suitable analogue for detail in visual long-term scene memory.</p>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"227 ","pages":"108525"},"PeriodicalIF":1.5,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142792343","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 psychophysical experiment was conducted, where 230 images of coloured text on neutral backgrounds were evaluated by 20 participants using a 6-point scale for visual comfort. Results showed that reading coloured text on a black background generally provided higher comfort compared to a white background. Additionally, visual comfort decreased as the text colour approached that of the background. The effect of text hue on comfort was not significant. Furthermore, several visual comfort models for mobile displays were developed and compared. The VC_1-LAB model is based on Bern’s attributes, while the VC_2-LAB model focuses on the lightness of text and background. The VC_3-LAB model includes both lightness and chroma attributes. Comparisons revealed that VC_3-LAB outperformed the others in predicting visual comfort, highlighting the importance of lightness and chroma in improving predictive accuracy.

For example, many medial superior temporal (MST) neurons are tuned to heading direction of self-motion based on visual (optic flow) signals and vestibular signals. Middle temporal (MT) cortical neurons are tuned to object depth from signals of two visual modalities: motion parallax and binocular disparity. A MST neuron’s preferred heading directions from different senses can be congruent (matched) or opposite from each other. Similarly, the preferred depths of a MT neuron from the two modalities are congruent in some neurons and opposite in other neurons. While the congruent tuning appears natural for cue integration, the functions of the opposite tuning have been puzzling. This paper explains these tunings from the efficient coding principle that sensory encoding extracts as much sensory information as possible while minimizing neural cost. It extends the previous applications of this principle to understand neural receptive fields in retina and the primary visual cortex, particularly multimodal encoding of cone signals or binocular signals. Congruent and opposite sensory signals that excite the congruent and opposite neurons, respectively, are the decorrelated sensory components that provide a general purpose, efficient, representation of sensory inputs before task specific object segmentation and recognition. It can be extended to encoding signals from more than two sensory sources, e.g., from three cone types. This framework also predicts a wider tuning width for the opposite than congruent neurons, neurons that are neither congruent nor opposite, and how neural receptive fields adapt to statistical changes of sensory environments.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"226 ","pages":"Article 108489"},"PeriodicalIF":1.5,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142699188","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}

Results confirmed that cue location and rectangle orientation interactively influence object-based attention, with horizontal objects combined with upper left visual field cues eliciting faster responses than other conditions.
