Perception Flashcards
Perception
Experiences result from stimulation of the senses,interpreting stimuli or sensory info
View point variance
People’s ability to recognize an object even when it is seen from different viewpoint.
Bottom up processing
Signal that start from senses and then go to brain.
Top down processing
Signal that originate in brain and then go to senses if needed
Unconscious inference Helmholtz’s theory
Our perception is influenced by unconscious assumptions that are most likely to occur and also influenced by previous experiences
Apparent(evidently) movement
Movement is perceived, nothing is moving
Oblique effect
People can perceive horizontal and verticals more easily than other orientations
Bayesian inference
Prior probability of an outcome
Likelihood of the outcome
Brain ablation
Removing part of the brain
Temporal lobe
Responsible for object identity ( What )
Ventral pathway
The pathway that determine object identity and goes to temporal lobe,ventral means lower part of brain
Dorsal pathway
The pathway that leads to parietal lobe is responsible for objects location,dorsal means back or upper surface
Perception pathway
Ventral pathway,visual cortex to temporal lobe
Action pathway
Dorsal pathway ,visual cortex to parietal lobe
