FORM PERCEPTION |
The process of seeing a basic shape and size of the shape |
|
|
OBJECT RECOGNITION |
the process of identifying what the object is following form perception |
|
|
Bottom up influences |
Stimulus based things that influence perception |
|
|
Top-down influences |
Knowledge or expectation driven influences on perception |
|
|
Integrative agnosia |
A marked impairment in the ability to complete tasks that require patients to judge how the features of something are bound together to form complex objects |
|
|
Repetition priming |
Repeated exposure to a stimulus - the first exposure primes for the second exposure |
|
|
Word superiority effect |
Words are easier to perceive than isolated letters, as are words that have been recently seen or are frequently viewed |
|
|
Recognition by components (RBC) model |
Says that geons might serve as the basic building blocks of all the objects we recognise. |
|
|
Geons |
Simple shapes, such as cylinders, cones and blocks, that make up objects. According to Biederman we need, at most, 36 different geons to describe every object in the world. |
|
|
Prosopagnosia |
The inability to recognize faces |
|
|
Dichotic listening |
Hearing one input in one ear and a different input in the other ear - often used in research, with participants being told to attend to one channel, and ignore the other |
|
|
Shadowing |
Where participants repeat what they can hear from the attended channel in a dichotic listening task, so that researchers can tell that they are consciously attending to the correct channel only |
|

|
|
Change blindness |
An observers inability to detect changes to scenes even though they might be "obvious" - like the gorilla experiment |
|
|
Early selection |
Hypothesizes that the attended input is selected early on, and the other input receives very little attention |
|
|
Late selection |
Hypothesizes that all of the input is attended to in a relatively complete manner, and then the attended input is selected |
|
|
Spatial attention |
The ability to focus on a particular position in space,and thus be better prepared for any stimulus that appears in that position |
|
|
Perseveration error |
The tendency to produce the same response over and over even when its obvious that the task requires a change in response |
|
|
Automaticity |
Tasks that have been heavily practiced can become automatic (automatic tasks), whereas controlled tasks are not yet practiced or are tasks that continually vary so its not possible to develop a standard routine.
