chapter 7 Flashcards
You rely on knowledge stored in memory to interpret the environmental stimuli registered by your senses
perception
Requires both bottom-up and top-down processing
perception
the processes that give rise to your ability to create mental images are _____
exclusively top-down in nature
Also called imagery
mental imagery
Imagery is _____driven
knowledge
Refers to the mental representation of stimuli when those stimuli are not physically present in the environment
mental imagery
imagery is also important in what psychology field
clinical psychology
extremely important in the STEM disciplines
Spatial ability
he reported that his own thinking processes typically used spatial images, instead of verbal descriptions
Albert Einstein
T or F: imagery and perception are identical
false; Although imagery and perception share many characteristics, they are not identical
Considered imagery to be an important part of the discipline
Wundt and other early psychologists
Strongly opposed research on mental imagery because it could not be connected to observable behavior
behaviorists such as John Watson
T or F: people make judgments more quickly if they need to rotate a mental image just a short distance
true
Asked participants to look at pictures of a human hand and to identify whether they were viewing a left hand or a right hand
Kotaro Takeda
right-handers or left-handers: recognized a right hand faster than a left hand
right-handers
right-handers or left-handers: recognized right and left hands equally quickly
left-handers
right-handers or left-handers: recognized upright pictures faster—and more accurately—than upside-down pictures
both
they perform more slowly than younger people on a mental-rotation task
elderly people
especially skilled in looking at an arrangement of objects in a scene and mentally rotating that scene by 180 degrees
Deaf individuals
Why do deaf people perform so well on mental rotation tasks?
they have had extensive experience in watching a narrator produce a sign then, they must mentally rotate this sign 180 degrees. They need to perform this rotation frequently, so they can match the perspective that they would use when producing this sign
Showed no activity in the primary motor cortex
participants who had originally watched the electric motor as it rotated the figure
showed activity in the primary motor cortex
Participants who had rotated the original geometric figure with their hands
what lobes were activated when people were asked to rotate the figures
right frontal lobes and parietal lobes
what lobes were activated when people were asked to imagine rotating the figures
increased activity in the left temporal lobe, as well as in a part of the motor cortex
The research on mental rotation has practical implications for people who are _____
recovering from a stroke
Do our mental images resemble perception (using an analog code), or do they resemble language (using a propositional code)?
imagery debate
what code is perception
analog code
