Perception - Coggle Diagram
Perception
How Does the Brain Perceive?
Unconscious Inference
Assumptions made by the brain about input
Accidental viewpoint
Helmholtz
Top-down processing
Gestalt Principles
Similarity
Proximity
Continuity (good continuation)
Closure
Common Fate
Apparent Motion
Figure-Ground Configuration
Symmetry
Common Region
Perception = organising principles
Bottom-up processing
Environmental Regularities
More empirical than Helmholtz and Gestalt
Common physical properties of the environment
Oblique effect
E.g. The Dress (discount the illuminant)
Top-down processing
Bayesian Inference
The most 'abstract' theory
Probability of perception
Prior info
Likelihood
Top-down processing
The Importance of Action
Creates new viewpoints
Specifies how input has moved/changed on your retina
What is Perception?
Sensation
What you see is what you get
Perception
What you see is up to you
Interpretation of sensory data
Illusions
Ambiguity in perception
Bistable stimulus
Conscious perception
Segregating vs Grouping
The Thatcher Effect/Illusion (ahh faces!)
FFA- sees face as a whole
Occipital Face Area (OFA)- processes relationship b/n parts of face
Superior Temporal Sulcus (STS)- activated during social cues/events
The Inverse Problem
a.k.a. how to get 3D from a 2D image
Creating a precept
Bottom-up
Top-down
Perception + Action: What and Where
What
Pathway
Identity of object
Ventral
pathway (lower)
Where
Pathway
Location of object
Dorsal
pathway (upper)
Lesion studies
In Temporal Lobe
Agnosia
Apperceptive
Associative
Prosopagnosia
In Parietal Lobe
Optic ataxia
Balint syndrome
Approaches to Understanding Perception
Direct Perception Theories
Bottom-Up Processing
Perception comes from stimuli
Identify parts --> Put 'em together --> Recognition
Gestalt principles
Constructive Perception Theories
Top-Down Processing
Influences
Attention
Memory
Expertise
Sine wave speech (in audition)
Unconscious inference
Environmental regularities
Bayesian inference
