Original Source: Visual adaptation and face perception.

The appearance of faces can be strongly affected by the characteristics of faces viewed previously. These perceptual after-effects reflect processes of sensory adaptation that are found throughout the visual system, but which have been considered only relatively recently in the context of higher level perceptual judgements. In this review, we explore the consequences of adaptation for human face perception, and the implications of adaptation for understanding the neural-coding schemes underlying the visual ...

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 ...

Cleft Palate and Cleft Lip

Cleft means 'split' or 'separation', and in Cleft Palate and Lip, the palate and lip are split respectively. This occurs as a congenital abnormality because during development in the...

Tactile frequency discrimination is enhanced by circumventing neocortical adaptation

During adaptation, neocortical responses change as a result of repeated sensory stimulation, but it's unclear how this affects perception. Here the authors use optogenetics to mimic sensory evoked cor...

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...

Amblyopia In Early Childhood May Alter Speech Perception

Children with unresolved amblyopia during early childhood may have difficulty with visual-auditory speech integration and subsequent alterations in speech perception. Medscape Medical News

Declining intelligence in old age linked to visual processing

Researchers have uncovered one of the basic processes that may help to explain why some people's thinking skills decline in old age. Age-related declines in intelligence are strongly related to declin...

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...

Morphed images of Hollywood celebrities reveal how neurons make up your mind

(University of Leicester) Study reveals individual neurons in the human brain are triggered by the subject's conscious perception, rather than by the visual stimulus

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...

Interactions between concentric form-from-structure and face perception revealed by visual masking but not adaptation.

Findings from diverse subfields of vision research suggest a potential link between high-level aspects of face perception and concentric form-from-structure perception. To explore this relationship, t...

Noise and adaptation in multistable perception: Noise drives when to switch, adaptation determines percept choice.

We study the dynamics of perceptual switching in ambiguous visual scenes that admit more than two interpretations/percepts to gain insight into the dynamics of perceptual multistability and its underl...

The sound of your lips: electrophysiological cross-modal interactions during hand-to-face and face-to-face speech perception.

Recent magneto-encephalographic and electro-encephalographic studies provide evidence for cross-modal integration during audio-visual and audio-haptic speech perception, with speech gestures viewed or...

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...
