Three-hypothesis framework for the neural relationship between visual imagery and visual perception¶

Theory · All theories
Evidence · no claims cited

Description¶

The article organises the imagery-perception debate around three hypotheses attributed to Roland and Gulyás: anatomical separation of imagery and perception areas, imagery areas as a subset of perception areas, or identical areas for both. The review states "There are three main hypothesis regarding this subject" and then surveys neuroimaging, ERP, lesion and blind-subject evidence bearing on each. It uses this framework to structure the shared-mechanisms and separate-mechanisms sections and to motivate studying blind subjects as a test case.

Design Implications¶

Context¶

Requirements¶

• Empirical resolution requires methods able to distinguish primary visual cortex from visual association areas, which the article notes is difficult with some techniques

Constraints¶

• The article presents the framework as an open issue rather than adjudicating it definitively

Target Learners¶

• cognitive neuroscience researchers
• students of visual cognition

Target Learning Objectives¶

• understanding the neural basis of mental imagery and its relation to perception

Claims¶

Related Theories¶

• Reinforcement framework for cognitive learning: imagery as perception-like experience producing learning under ordinary principles
• Technology-imagery-perception (TIP) model
