Lecture 13 Flashcards
(10 cards)
What is the definition of Edge detector?
Another way of talking about cortical/corticol cells
What is the definition of Direct perception?
An ecological approach to vision, without the need for homunculus
What is the definition of Affordances?
An objects connection/relationship with the animal, the possibility of an action
What is Information processing?
In WWII:
- Technological advances in flight, tanks, artillery, training needs, code breaking etc. all required an investigation of human cognition
J.J. Gibson:
- Trained pilots in WWII and this later led to the development of his theories about direct perception and ‘ecological’ visual processes
What is Gibson’s theory?
Ecological optics:
- Light as information
Direct reception:
- We don’t see things secondary to the retinal image but we perceive them directly
- Indirect perception involves artwork
What is/are Ecological optics?
- Not just light
- rich array of structured information
- they way we interact with the environment is important
What is/are Affordances?
- “The Affordances of the environment are what it offers the animal, what it provides or furnishes, either for good or for ill”
- invariant properties of objects (object constancy)
- not based on physical characteristics
- must be relative to the organism
What is Resonance?
- Gibson said we get information from the environment through ‘resonance’
- (a bit like picking up radio waves)
- Resonance is resonating to our surroundings
- tuning forks ossilating together
How can we apply resonance to Psychology/humans?
- For our purposes
- Resonance for getting information from the surroundings
What are the Strengths of Resonance?
- Ecological person, grounding a person in the real world
- tries to account for action and vision for a purpose - affordances
- incorporates invariance and object constancy
