Two rectangular stimuli with a prescribed width and relative offset are subjected to a Gaussian blur. Fixational drift shifts the resulting signal with time. The perceived signal is the weighted average over the history of local stimulation encoded by an adaptation kernel. We model this kernel as a difference of two exponentials, introducing two timescales describing initial integration and eventual recovery of a receptor. Ultimately, Gaussian white noise is added to capture random receptor fluctuations. Based on the Bayesian estimation of location and relative offset of both stimuli, we can study Vernier performance through numerical simulation as well as through analytical approximation for different eye movements. Analyzing diffusive motion in particular, we extract the diffusion constant that optimizes stimulus localization for long observation times. This optimal diffusion constant is inversely proportional to an average of the two timescales describing adaptation and proportional to the square of the larger of stimulus size or blurring width, giving rise to two separate regimes. We generalize our analysis to optimize discrimination and extend the class of eye motions considered beyond purely diffusive drift, e.g. with the inclusion of persistence.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"8"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144013254","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}

Here we sought to establish device-specific control data for future studies of individuals with retinal disease. We used AOSLO to quantify the cone mosaic and measure visual acuity in the dominant eye of 18 individuals (7M, 11F; 15-67 years) without retinal pathology. Average density at the cone density centroid was 186,925 cones/mm^2. Visual acuity was assessed using an AO-corrected Snellen E presented via a QUEST-driven four-alternative forced-choice task. The mean observed acuity across individuals was -0.23 (±0.08) logMAR. We compared observed acuity to that predicted by foveal cone spacing, using the average spacing within a given individual's 95% bivariate contour ellipse area centered on an estimated preferred-retinal fixation locus. The mean (± SD) predicted acuity across individuals was -0.30 (±0.03) logMAR. The ratio of observed:predicted acuity ranged from 1.54 to 0.30 (average = 0.78). Six individuals had observed acuity equal to or better than that predicted by their foveal cone spacing, while the other 12 had an observed acuity worse than that predicted by their foveal cone spacing. These results warrant further examination of factors contributing to the variation of AO-based acuity measures, including experimental differences, internal response bias, and other biological factors.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"20"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144022667","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}

Research on chromatic adaptation under natural viewing has exposed observers to simple transformations using filters or lenses (Neitz et al.,2002, Engel et al., 2016). It is an open question whether our visual system adapts to complex chromatic transformations as it does for complex visuospatial manipulations (Richter et al., 2002). Altered reality (AR) devices allow us to address this question. Grush et al., (2015) provided qualitative evidence from two observers that their perceptual experience of colour was altered after AR exposure to a hue-rotated world. We exposed observers to a real-time pass-through feed in an AR headset (Meta Quest 3), applying a hue rotation of 120 degrees in HSL space (e.g., blue sky turns magenta). Observers (N = 8) were immersed in either a positive or negative hue rotation during which they interacted with the unnaturally coloured world through everyday activities including walking in nature, painting, selecting and eating food, etc. We measured the observers' perception of unique yellow and unique blue prior to adaptation and each hour during their exposure to the hue-rotated world, for up to four hours. Our results expose the limits of visual adaptability, elucidating whether adaptation extends to unnatural chromatic transformations and attempt to shed light on the temporal characteristics of long-term adaptation.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"40"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144024509","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}

In scotopic vision, \"white\" patches appear gray - brightness perception is clipped at the upper end of the range. In photopic vision, darks are perceived as relatively more intense than lights. Here, we compared perception of contrast polarities in photopic, mesopic, and scotopic viewing. We tested the perception of positive and negative contrasts in the three viewing conditions, using a circular stimulus (2° radius) presented for 200 ms at 8° eccentricity. In a detection task, we obtained absolute thresholds for positive and negative contrasts. In a matching task, we obtained PSEs when participants compared stimuli with positive and negative contrasts at three contrast levels (0.2, 0.35, 0.5). Stimuli were defined in Weber's contrast. In the detection task, thresholds were highest in scotopic and lowest in photopic vision. Thresholds were higher for positive than negative contrasts in mesopic and scotopic but not in photopic viewing. In the matching task, the asymmetry was increased in scotopic compared to photopic viewing, such that even more positive contrast was required to match negative contrasts. Our results show that the asymmetry in contrast perception depends on the lighting condition, being largest in scotopic vision in both tasks. As signals from cone receptors are crucial for perceiving \"white\", the clipped range in scotopic vision also seems to impede the perception of positive contrasts.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"47"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003187","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}

In postreceptoral colour processing, the outputs of the three cone types are first compared by two cone-opponent mechanisms, L/(L+M) and S/(L+M). In anomalous trichromacy, the separation between L and M cone peak spectral sensitivities is reduced compared to normal trichromacy, leading to decreased sensitivity for L/(L+M) colour differences. However, colour appearance is more similar to that of normal trichromats than cone-opponent models predict. Current evidence suggests this is due to postreceptoral compensation in the cortex, where reduced colour signals are amplified to use available neural resources. We devised a novel approach to investigate the site of postreceptoral compensation using steady-state visually evoked potentials (SSVEPs), captured by electroencephalography. We measured signals in response to flickering stimuli designed to isolate the S/(L+M) and L/(L+M) cone opponent mechanisms at both retinal and cortical sites. If compensation is cortical, we would expect any reduction for anomalous trichromats in retinal L/(L+M) SSVEP signals compared to S/(L+M) SSVEP signals to be rectified at the cortical site. Our study did not exclude the possibility of retinal compensation, in contrast to an existing fMRI study (Tregillus et al., 2021, Curr. Biol.). We present our novel method to address potential challenges in characterising these processes.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"25"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144044728","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}

Alternatively, the \"generic procedural learning\" account suggests that a general search strategy is developed for all displays, although repeated contexts play a higher weight in optimizing the strategy due to their higher presented frequency. This makes responses faster for repeated displays than novel displays. The current study examined these two mechanisms using a varied contextual cueing paradigm to analyze response time (RT) variability with the coefficient of variation (CV) and time-frequency analysis of RTs. Experiment 1 involved uninterrupted training with repeated and novel displays presented separately, followed by a test with randomly interleaved repeated and novel displays. Experiment 2 used interleaved displays for training before an uninterrupted test phase. Both experiments revealed faster RTs and reduced template-based variability for repeated displays early in the training, supporting attentional guidance. However, generic procedural learning, indicated by a late onset of lower cross-display variability for repeated displays, required more time and training to validate the cueing effect. These findings suggest that attentional guidance dominates early learning, but both mechanisms contribute to the contextual cueing effect overall.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 4","pages":"1"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11977797/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765624","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}

In vivo images of the photoreceptor mosaic acquired using an Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO) are systematically distorted by eye motion. Most methods to extract FEMs from AOSLO data rely on comparison to a motion-free reference, giving eye-position as a function of time. MS are subsequently identified using adaptive velocity thresholds (Engbert & Kliegl, 2003). We use computer vision and machine learning (ML) for detection and characterisation of MS directly from raw AOSLO images. For training and validation, we use Emulated Retinal Image CApture (ERICA), an open-source tool to generate synthetic AOSLO datasets of retinal images and ground-truth velocity profiles (Young & Smithson, 2021). To classify regions of AOSLO images that contain a MS, images were divided into a grid of 32-by-32-pixel sub-images. Predictions from rows of sub-images aligned with the fast-scan of the AOSLO were combined, giving 1ms resolution. Model performance was high (F1 scores >0.92) across plausible MS displacement magnitudes and angles, with most errors close to the velocity threshold for classification. Direct velocity predictions were also derived from regression ML models. We show that ML models can be systematically adapted for generalisation to real in vivo images, allowing characterisation of MS at much finer spatial scales than video-based eye-trackers.","PeriodicalId":49955,"journal":{"name":"Journal of Vision","volume":"25 5","pages":"5"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144039692","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}
