The face is made of various features in which faces are recognised holistically. Signup and view all the answers

Tanake & Farah presented cartoon faces. The participants had to learn them then were presented with a single feature from those cartoon faces (e.g.nose). The participants had to figure out which face the single feature belonged to. Results were :

Participants found it difficult to identify which face the feature belonged to especially when the faces were not present. Signup and view all the answers

Study Notes

Retinal Movement System

No information provided about the Retinal movement system

Visual Perception

6-month-old babies can distinguish between two monkeys, and this ability remains throughout their lives

Face Perception

Grandmother cells are highly specific cells
Tanake & Farah's study: participants learned cartoon faces and then identified single features (e.g. nose) to recognize the corresponding face
Results: negative images (light areas appear dark and vice versa) make face identification difficult

Motor Control

The PMd (premotor dorsal area) is responsible for external-generated actions
The Supplementary Motor Area has unknown functions (question did not specify which function is NOT part of it)

Neuroplasticity

Long-term potentiation (LTP) has unknown principles (question did not specify which principle is NOT part of LTP)

Visual Illusions

Thatcher illusions: no specific conclusion mentioned

Activation

V9 is activated by unknown stimuli (question did not specify what activates V9)
