Final Exam Flashcards
1
Q
Visual Imagery
A
“seeing” in the absence of a visual stimulus
2
Q
Mental Imagery
A
experiencing a sensory impression in the absence of sensory input (applies to all of the senses)
3
Q
Imageless Thought Debate
A
scientific debate over whether thinking can occur w/o imagery
4
Q
Paired-Associate Learning
A
- participants presented w/ word pairs, later presented w/ first word and asked to recall its pair
- found memory for words evoking mental images is better than for those that do not
5
Q
Mental Chronometry
A
- participants mentally rotate one object to see if it matches other object
- greater separation between shapes = longer response time
6
Q
Mental Scanning Technique
A
- create mental image and scan from one end to the other in their mind
- took participants longer to mentally move long distances than shorter distances
- like perception, imagery is spatial OR more distractions during scanning increase reaction time
7
Q
Propositional Representations
A
- abstract, language-like descriptions
- similar to semantic networks; concepts linked by descriptive relationships
- not as likely as spatial
8
Q
Imagery Size Experiment
A
- imagined 2 different sized animals side by side and asked descriptive questions about one of them (ex. rabbit)
- responded faster when rabbit was imagined larger (next to fly) than when it was smaller (next to elephant)
- larger mental images allow easier access to detail; similar to real-world perception
9
Q
Mental Walk Task
A
- imagine walking toward animal, report when image “overflows” visual field
- closer distance for smaller animals, farther distance for large animals
- mimics real-world experience indicating mental images are spatial
10
Q
Perky (1910)
A
- visualize object projected on screen, unknown that same object is actually faintly projected
- mental images then match projected images
- suggests strong overlap between perception and imagery
