Visual acuity

Visual acuity (VA) is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. Visu...

Tinnitus

Tinnitus causes people to hear constant sounds in one ear, both ears or in their head. Tinnitus is the medical name for the perception of noise in one ear, both ears or in the head. The noise comes ...

Want to distract someone? An emotional face might work

The sudden appearance of a face within our visual field can affect the motor action accompanying a gesture even if the face is totally unrelated to what we are doing and even if we try to ignore it. W...

Hues and cry

A blue dress divided the Internet — and put the science of visual perception in the spotlight.

The Over and Under of Shoe Tying

This ADL requires bilateral hand coordination, manual dexterity, fine motor planning, and visual perception.

Faces that distract from actions

The sudden appearance of a face within our visual field can affect the motor action accompanying a gesture even if the face is totally unrelated to what we are doing and even if we try to ignore it. A...

The dissociable effects of punishment and reward on motor learning

Human motor adaptation is often described as an automatic process insensitive to reward- or punishment-based feedback. Contrary to this hypothesis, Galea et al. show through a double dissociation that...

Elderly brains learn, but maybe too much

A new study led by Brown University reports that older learners retained the mental flexibility needed to learn a visual perception task but were not as good as younger people at filtering out irrelev...

Visual recognition memory, manifested as long-term habituation, requires synaptic plasticity in V1

The authors find that behavioral habituation to the repeated presentation of visual stimuli, measured as reduced occurrence of a brief motor response called a 'vidget', depends on primary visual corte...

Visual objects are represented by a distributed network in human brain

New research involves recording single-neuron activity in the brains of epilepsy patients who require electrodes implanted to monitor seizures. With the electrodes in place, processes such as percepti...

Beyond the FFA: The role of the ventral anterior temporal Lobes in face processing.

Extensive research has supported the existence of a specialized face-processing network that is distinct from the visual processing areas used for general object recognition. The majority of this work...

Probing the functions of contextual modulation by adapting images rather than observers.

Countless visual aftereffects have illustrated how visual sensitivity and perception can be biased by adaptation to the recent temporal context. This contextual modulation has been proposed to serve a...

High temporal frequency adaptation compresses time in the Flash-Lag illusion.

Previous research finds that 20Hz temporal frequency (TF) adaptation causes a compression of perceived visual event duration. We investigate if this temporal compression affects further time-dependent...

Visual Speech Perception in Foveal and Extrafoveal Vision: Further Implications for Divisions in Hemispheric Projections.

When observing a talking face, it has often been argued that visual speech to the left and right of fixation may produce differences in performance due to divided projections to the two cerebral hemis...

Gaze direction affects the magnitude of face identity aftereffects.

The face perception system partly owes its efficiency to adaptive mechanisms that constantly recalibrate face coding to our current diet of faces. Moreover, faces that are better attended produce more...
