Apperceptive Agnosia |
people who suffer from it can see, but not organize theelements they see to perceive an intact object |
|
|
Bottom up processing |
First comes the response in the body (eyes see the bowl and contents, nose smells chocolate, pickles, and hot sauce, stomach churns, face grimaces, head turns away). This leads to emotion (repulsion, disappointment) and the brain's cognition and directive for action (thinking 'That's nasty' and saying 'No thank you.'). |
|
|
Top Down Processing |
processing that refers to how our brains make use of information that has already been brought into the brain by one or more of the sensory systems. This processing is a cognitive process that initiates with our thoughts, which flow down to lower-level functions, such as the senses |
|
|
Integrative Agnosia |
can perform well in tasks asking themto detect features in a display, however, these people are markedly impaired intasks requiring them to judge how these features are bound together |
|
|
apperceptive agnosia |
disorder that involves the inability to assemble various aspects of an input into an organized whole
|
|
|
tachistoscopic presentations |
Being shown a stimulus briefly |
|
|
Word Superiority Effect |
Words are easier to perceive than individual letters |
|
|
Degree of Well-Formedness |
it's easier to recognize/predict a word if its organized like a regular English word |
|
|
Feature Nets |
Detectors are connected to one another and arranged in layers. feature detectors, letter detectors, and word detectors |
|
|
Bigram Detectors |
Allow us to explain well formedness -Familiar letter combination (CL, CK) would require less activation to fire than unfamiliar ones (CQ, CX) |
|
|
The McClelland and Rumelhart Model |
involves a mechanism through which detectors can inhibit one another so thatactivation of one detector can decrease that of another |
|
|
Recognition by Components |
a bottom-up process proposed by Irving Biederman to explain object recognition States we are able to recognize objects by separating them into geons (the object's main component parts). |
|
|
Viewpoint independent |
we recognize an object as being the same from a number of different angles
|
|
|
Geons |
Basic component of objects -small number 36 -its components are recognized across different orientations and view points |
|
|
Viewpoint-dependent |
dependent on mental rotation |
|
|
Prosopagnosia |
generally have normal vision they can tell what things are and if something is a face, and probably the gender of thatface, and the age but they can’t recognize individual faces, unable to recognize someone,even if they know them really well, by looking at their face |
