Low‐contrast visual acuity versus low‐luminance visual acuity in choroideremia
Clinical relevance Choroideremia is a progressive X‐linked inherited rod‐cone dystrophy. Patients present with nyctalopia and progressive visual field loss, but visual acuity remains well preserved early on. This study showed that low‐luminance visual acuity may be a useful clinical outcome measure during earlier disease stages.

Identifying Objective EEG Based Markers of Linear Vection in Depth
This proof-of-concept study investigated whether a time-frequency EEG approach could be used to examine vection (i.e., illusions of self-motion). In the main experiment, we compared the event-related spectral perturbation (ERSP) data of 10 observers ...

Stimulus frequency alone can account for the size effect in number comparison
In a number comparison task, the size effect (i.e, smaller values are easier to compare than larger values) is usually attributed to a psychophysics-based representation.

New developments in clinical psychophysics allow a non-invasive assessment of visual function which may otherwise not be possible. Measurements of spatial and temporal contrast sensitivity functions, perimetric rod and cone sensitivity, colour vision testing, and newer tests such as hyperacuity thresholds may provide information about the mechanism of ...

PsyPhy: A Psychophysics Driven Evaluation Framework for Visual Recognition [PDF]
By providing substantial amounts of data and standardized evaluation protocols, datasets in computer vision have helped fuel advances across all areas of visual recognition. But even in light of breakthrough results on recent benchmarks, it is still fair

The Irreducibility of Vision: Gestalt, Crowding and the Fundamentals of Vision
What is fundamental in vision has been discussed for millennia. For philosophical realists and the physiological approach to vision, the objects of the outer world are truly given, and failures to perceive objects properly, such as in illusions, are just

Perceived Azimuth Direction Is Exaggerated: Converging Evidence From Explicit And Implicit Measures [PDF]
Recent observations suggest that perceived visual direction in the sagittal plane (angular direction in elevation, both upward and downward from eye level) is exaggerated.

Focusing and orienting spatial attention differently modulate crowding in central and peripheral vision [PDF]
The allocation of attentional resources to a particular location or object in space involves two distinct processes: an orienting process and a focusing process.

The Historical Development of Easter-Southern Freight Rate Relationships [PDF]
A method for creating and presenting video-recorded synchronized audiovisual stimuli at a high frame rate-which would be highly useful for psychophysical studies on, for example, just-noticeable differences and gating-is presented.
