Chapter 7 Flashcards
the mental representation of visual stimuli
Visual Imagery
the mental representation of auditory stimuli
Auditory Imagery
___relies completely on top-bottom processing because your sensory receptors do not receive any input when you create a mental image.
Imagery
The use of previous knowledge to gather and interpret stimuli registered by the senses. ___ requires both bottom up and top down processing.
Perception
most mental images are ___ about two thirds
visual
Behaviorist thoughts on mental imagery
behaviorist strongly opposed research on mental imagery because it could not be connected to observable behavior.
research on ___ is difficult to conduct especially because researchers cannot directly observe ___ ___ and because they fade away quickly
Mental imagery
____ Is a method to study mental images.
Mental Rotation
An important controversy: Do mental images resemble perception (using analog code) or do they resemble language using (a propositional code)
Imagery Debate
In the imagery debate an abstract language like representation. this form of storage is neither visual nor spatial, and it doe not physically resemble the original stimulus
Propositional Code
The inability to recognize human faces visually, though other objects may be perceived relatively normally. People with prosopagnosia also have comparable problems in creating visual imagery of faces.
Prosopagnosia
In the imagery debate a mental representation that closely resembles the physical object. you can create a mental image of an object that closely resembles the actual perceptual image on your retina.
Analog code
when you look at a triangle the features of the triangle are registered in your brain in a form that preserves the physical relation ship among the three lines is an example of
Analog Code
When you look at a triangle your brain will register a language like description of the lines and angles. your brain can then use this verbal description to generate a visual image.
Propositional Code
mental rotation supports what kind of perspective?
Analog Code
why does mental rotation support the Analog Code
because the time it takes to rotate the physical figure 160 degrees is longer than the time it would take to rotate it 20 degrees. In contrast the proposition code would estimate the same amount of reaction time.
we treat mental images similar to the way we treat physical objects when we rotate them through space. in both cases it takes longer to perform a large mental rotation than a small one is in support of what perspective
Analog Code
deaf individuals who are fluent in ALS are very skilled at looking at an arrangement of objects in a scene and mentally rotating that scene by 180 degrees. why?
because they have had extensive experience watching a narrator produce signs and they must mentally rotate this sign 180 degrees to understand it.
upright pictures are more quickly recognized than downward images because we are used to perceiving them upright therefore it supports the
Analog Code
In research when researchers biases and expectations influence the outcomes of an experiment.
Experimenter Expectancy
Visual Imagery and distance
participants needed more time to scan a large mental distance compared to a small mental distance.
reasearch on distance and visual imagery support what perspective
Analog Code
Visual Imagery and Shapes research showed that
when two angels are similar in size it takes longer to determine what angel was smaller. when two angels are very different in size it took participants a shorter time. just like in real life it takes longer time to make decisions when two angles are very similar to each other than when the two angles are very different.
