|
Sensation
|
The information we receive from our five senses and is sent to our brain to be processed.
|
|
|
Perception
|
uses previous knowledge to gather and interpret the stimuli registered by the senses.
Combines visual stimuli with knowledge |
|
|
Distal Stimulus
|
The actual object that is "out there" in the environment.
|
|
|
Proximal Stimulus
|
the information registered on your sensory receptors.
|
|
|
Sensory Memory
|
Large capacity, records information from each of the senses with reasonable accuracy.
|
|
|
Iconic Memory
|
our visual memory that will preserve an image even though it has disappeared
|
|
|
Gestalt Psychology
|
study the fact that humans have basic tendencies to organize what they see; without any effort we recognize patterns over random arrangements.
|
|
|
Illusory contours
|
we see edges even though none are there
|
|
|
Template-Matching Theory
|
you compare a stimulus with a set of templets. (specific patterns you have stored in your memory)
Ex. I see the letter P and recognize it because i have a templete of that shape in my mind |
|
|
Feature-Analysis Theory
|
Visual stimulus is composed of a small number of characteristics or components. These components are called distinctive features.
EX. we recognize a P because of it's straight line and its curve to the right that meets back halfway down. |
|
|
Recognition-by-components Theory
|
A specific view of an object can be represented as an arrangement of simple 3D shapes called Geons.
|
|
|
Viewer-Centered Approach
|
This approach proposes that we store a small number of views of 3D objects, rather than one view.
|
|
|
Bottom-Up Processing
|
The recognition of stimulus from our sensory receptors.
|
|
|
Top-Down Processing
|
Our mental level of processing where we use our concepts, expectations, and memory to help us identify object. Our top level of processing will help us understand the earlier processed stimuli
|
|
|
Word Superiority Effect
|
The ability to identify a letter more accurately and more rapidly when it is produced in a word rather than alone or in a jumble of letters
|
|
|
Change Blindness
|
Overuse of our top-down processing. We fail to detect a change in an object or scene.
|
|
|
Inattention Blindness
|
when we are paying attention to some events in a scene, we may fail to notice when an unexpected but completely visible object appears. (Gorilla/basketball video)
|
|
|
How do we perceive faces?
|
We recognize faces on a holistic basis. Meaning we perceive it in terms of it's gestalt, or overall qualities combined.
|
|
|
Prosopagnosia
|
a condition in which people cannot recognize human faces visually though they can perceive other objects normally.
|
|
|
Visual Agnosia
|
Inability to recognize visual objects.
|
|
|
Associative Agnosia
|
Object Agnosia, Can't assign meaning to an object. They can recognize what keys are by shape but not what they do.
|
|
|
Apperceptive Agnosia
|
Can recognize color, brightness, acuity, but can't recognize the shape of it.
|
|
|
Object/Pattern Recognition
|
Your ability to identify a complex arrangement of sensory stimuli, and you perceive that this pattern is separate from its background.
|
