| studying perception as it naturally occurs in environment |
|
|
Term
|
Definition
| all info necessary for perception is in stimulus; perceptual system doesn't add/compute anything to stimulus for perception to occur |

Term
|
Definition
| composed of surfaces(table top, book cover) |
|
|
Term
| light reflects off surfaces |
|
Definition
| contains info about objects |
|
|
Term
|
Definition
| who uses this info from reflected life to perceive distal stimulus |
|
|
Term
|
Definition
| when you are this, receive little info from environment, simialr to lab experiments |
|
|
Term
|
Definition
| when doing this, receive more info from environment, similar to perceiving in real life |
|
|
Term
|
Definition
| light structure created by surfaces, textures, and contours in environment |
|
|
Term
|
Definition
| flow of visual stimuli in environment; relative to viewer; moving optic array |
|
|
Term
|
Definition
| property that remains constant as viewer moves through environment |
|
|
Term
| focus of expansion is invariant |
|
Definition
| no flow where viewer is moving towards/away |
|
|
Term
| optic flow provides info about |

Definition
| optic flow relationship between flow and movement |
|
|
Term
|
Definition
|
|
Term
|
Definition
| provides info on movement, leads to more movement |
|
|
Term
| as viewer moves toward object (invariant info) |
|
Definition
object- appears to get large
object's visual angle- increases
size of proximal stimulus- increases |
|
|
Term
| objects size (invariant info) |
|
Definition
| increases at constant rate |
|
|
Term
| rate of increase (invariant info) |
|
Definition
| invariant, increase-invariant |
|
|
Term
| use optic flow and invariant info |
|
Definition
| use these 2 things to determine speed and direction |
|
|
Term
|
Definition
| what object, or surface, furnishes viewer; perceive not only physical property of object but what object can do for viewer |
|
|
Term
|
Definition
| stimulus doesn't need to be furthur analyzed, everything needed for perception is available in proximal stimulus |
|
|
Term
| Marr's Computational Approach |
|
Definition
| stimulus undergoes different computaitons before end results of perception |
|
|
Term
|
Definition
| perception is complex; ecological perspective over simplifies perception |
|
|
Term
| Empirical Support for Eco psych |
|
Definition
| people accurate in direction judgements ; use optic flow and FOE in navigating |
|
|
Term
|
Definition
| don't need optic flow to navigate in environment; can walk in dark, novel room; Blind Walking Experiments |
|
|
Term
| Blind Walking Experiments |
|
Definition
| accurate in stopping within feet of target; can navigate in environment without optic flow |
|
|
Term
|
Definition
| Flow info is involved with maintaining posture |
|
|
Term
|
Definition
| walls meant to duplicate visual stimulation when walking; walls move forward-flow expands and walls move back- flow contracts and viewer uses this info to maintain posture |
|
|
Term
|
Definition
| when walls moved forward-kids moved back; when walls moved back- kid moved forward; 1/3 fell over; kids fixed posture based on visual info |

|
Definition
| catcher runs so view of ball follows straight line path; curved path |
