Using psychophysics to ask if the brain samples or maximizes.
The two-alternative forced-choice (2AFC) task is the workhorse of psychophysics and is used to measure the just-noticeable difference, generally assumed to accurately quantify sensory precision.

Abstract In this contribution to a book symposium on Gregory of Nyssa’s On the Human Image, Morwenna Ludlow reflects on John Behr’s attention to the literary structure and argumentative flow of the book, its interplay with the similarly structured Timaeus of Plato and the difficulties of translating a work of such rhetorical and pastoral sophistication

Spectral tuning and after-effects in neural entrainment
Neural entrainment has become a popular technique to non-invasively manipulate brain rhythms via external, periodic stimulation. However, there is still debate regarding its underlying mechanisms and effects on brain activity.

Underpowered samples, false negatives, and unconscious learning [PDF]
The scientific community has witnessed growing concern about the high rate of false positives and unreliable results within the psychological literature, but the harmful impact of false negatives has been largely ignored. False negatives are particularly

Background Social anxiety disorder (SAD) in youth is associated with significant psychosocial impairments; however, the cognitive and neural mechanisms that maintain it, particularly during childhood and adolescence, remain underexplored. Cognitive models emphasize the role of altered face processing, and neutral facial expressions may be perceived as ...

Psychophysics Phenomenologized? Sensation and Decision in Visual Motion Perception
Experimental phenomenology and psychophysics are two rather different approaches to the study of perception, and rely on first-person descriptions and third-person measurements of the percept, respectively.

Interpretation of absolute judgments using information theory: channel capacity or memory capacity? [PDF]
Shannon’s information theory has been a popular component of first-order cybernetics. It quantifies information transmitted in terms of the number of times a sent symbol is received as itself, or as another possible symbol.

How do changes in speed affect the perception of duration? [PDF]
Six experiments investigated how changes in stimulus speed influence subjective duration. Participants saw rotating or translating shapes in three conditions: constant speed, accelerating motion, and decelerating motion.

Abstract Post‐stroke fatigue (PSF) is a prevalent symptom associated with attention deficits. However, it is currently unclear what drives these. Here we applied Load Theory of Attention to investigate the role of perceptual load in the relationship between attention, distraction and fatigue levels in PSF.
