Glossiness perception and its pupillary response
Vision Res. 2024 Apr 4;219:108393. doi: 10.1016/j.visres.2024.108393. Online ahead of print.ABSTRACTRecent studies have revealed that pupillary response changes depend on perceptual factors such as subjective brightness caused by optical illusions and luminance. However, the manner in which the perceptual factor that is derived from the glossiness perception of object surfaces affects the pupillary response remains unclear. We investigated the relationship between the glossiness perception and pupillary response through a glossiness rating experiment that included recording the pupil diameter. We prepared general object im...

A new mouse-fixation device for IOP measurement in awake mice
Vision Res. 2024 Apr 4;219:108397. doi: 10.1016/j.visres.2024.108397. Online ahead of print.ABSTRACTGlaucoma is an irreversible blinding eye disease. The mechanisms underlying glaucoma are complex. Up to now, no successful remedy has been found to completely cure the condition. High intraocular pressure (IOP) is an established risk factor for glaucoma and the only known modifiable factor for glaucoma treatment. Mice have been widely used to study glaucoma pathogenesis. IOP measurement is an important tool for monitoring the potential development of glaucomatous phenotypes in glaucoma mouse models. Currently, there are two ...

Performance on a contour integration task as a function of contour shape in schizophrenia and controls
Vision Res. 2024 Apr 4;219:108394. doi: 10.1016/j.visres.2024.108394. Online ahead of print.ABSTRACTContour Integration (CI) is the ability to integrate elemental features into objects and is a basic visual process essential for object perception and recognition, and for functioning in visual environments. It is now well documented that people with schizophrenia (SZ), in addition to having cognitive impairments, also have several visual perceptual deficits, including in CI. Here, we retrospectively characterize the performance of both SZ and neurotypical individuals (NT) on a series of contour shapes, made up of Gabor elem...

Sustaining attention in visuomotor timing is associated with location-based binding
Vision Res. 2024 Apr 2;219:108405. doi: 10.1016/j.visres.2024.108405. Online ahead of print.ABSTRACTMaintaining focus of attention over prolonged periods can be challenging, especially when the target stimulus is absent from the temporal sequence. Prior research has shown that a temporal attentional cue filling in the temporal blank can improve sustained attention: in a sustained visual attention task requiring synchronizing finger tapping with a temporally regular sequence composed of brief flash disks interleaved with blank periods, task performance was improved when a continuous fixation point that served as a temporal ...

The role of pattern coherence in interocular grouping during binocular rivalry: Insights from individual differences
Vision Res. 2024 Apr 2;219:108401. doi: 10.1016/j.visres.2024.108401. Online ahead of print.ABSTRACTInterocular grouping during binocular rivalry occurs when two images presented to each eye combine into a coherent pattern. The experience of interocular grouping is thought to be influenced by both eye-of-origin, which involves excitatory lateral connections among monocular neurons, and pattern coherence, which results from top-down intervention from higher visual areas. However, it remains unclear which factor plays a more significant role in the interocularly-grouped percepts during binocular rivalry. The current study em...

In primary visual cortex fMRI responses to chromatic and achromatic stimuli are interdependent and predict contrast detection thresholds
Vision Res. 2024 Mar 28;218:108398. doi: 10.1016/j.visres.2024.108398. Online ahead of print.ABSTRACTChromatic and achromatic signals in primary visual cortex have historically been considered independent of each other but have since shown evidence of interdependence. Here, we investigated the combination of two components of a stimulus; an achromatic dynamically changing check background and a chromatic (L-M or S cone) target grating. We found that combinations of chromatic and achromatic signals in primary visual cortex were interdependent, with the dynamic range of responses to chromatic contrast decreasing as achromati...

Aerial single target acuity of harbor seals (Phoca vitulina) for stationary and moving targets of varying contrast
Vision Res. 2024 Mar 25;218:108389. doi: 10.1016/j.visres.2024.108389. Online ahead of print.ABSTRACTHarbor seals (Phoca vitulina) need to detect single objects for example when orienting to landmarks or hunting prey. The detection of single objects, described by the single target acuity (STA), cannot be deduced from formerly determined grating acuity (GA) as different mechanisms underlie STA and GA. Thus, we assessed STA for stationary and moving single targets with varying contrast in two harbor seals in a first approach in air. In a two-alternative-forced-choice discrimination task, the seals had to indicate whether the...

Empirical tests of the effectiveness of EnChroma multi-notch filters for enhancing color vision in deuteranomaly
Vision Res. 2024 Mar 25;218:108390. doi: 10.1016/j.visres.2024.108390. Online ahead of print.ABSTRACTManufacturers of notch filter-based aids for color vision claim that their products can enhance color perception for people with anomalous trichromacy, a form of color vision deficiency (CVD). Anecdotal reports imply that people with CVD can have radically enhanced color vision when using the filters. However, existing empirical research largely focussed on the effect of notch filters on performance on diagnostic tests for CVD has not found that they have any substantial effect. Informed by a model of anomalous trichromatic...
