Flashcards in Week 6 - Ecological Psychology Deck (11):
1

Principles of Ecological Psychology:
What is Ecological Validility?

Humans have evolved perception-action systems to deal with real stimuli

2

Principles of Ecological Psychology:
What is direct perception?

Humans perceive relevant details about the world without an internal model (tap into relevant enviromental info)

3

Principles of Ecological Psychology:
What are affordances

What humans perceive is 'reachable' can happen.

4

Principles of Ecological Psychology:
What is Kinetic theory

Lawlike mapping from perceptual variables to action

5

Which of the proposed strategies for controlling locomotion is consistent with ecological psychology?

Optic Flow

6

What are the two proposed strategies for controlling locomotion?

Optic flow and egocentric direction

7

What information does Tau provide?

Time to reach target

8

What information does optic flow provide?

Direction of movement

9

What is the difference between direct perception and information processing approach?

In ecological psychology, we use features in the environment to control movements without representing those features in our brain. Information processing, on the other hand, suggests that we form a model of the world in our head and use that model to control movements.

10

Why is ecological validity important to ecological psychology?

Our perceptual-action systems use natural environment and movements, so ecological validity means we test these movements in 'natural' tasks

11

What is dynamic touch?

We can perceive the properties of objects by holding them, can determine length, mass and volume.
