2. Cognition 7e, Margaret Matlin Chapter 7 The Characteristics of Mental Images not directly observable
fade quickly
Imagery debate
perception vs. language
analog code (depictive representation/pictorial representation) vs. propositional code (descriptive representation)
3. Cognition 7e, Margaret Matlin Chapter 7 The Characteristics of Mental Images studying mental imagery—if a mental image resembles a physical object, then people must make judgments about a mental image in the same way that they make judgments about the corresponding physical object
4. Cognition 7e, Margaret Matlin Chapter 7 The Characteristics of Mental Images Imagery and Rotation
Shepard and Metzler's Research
same/different task using pairs of line drawings images
two- vs. three-dimensions
reaction time to decide same/different
decision time influenced by the amount of rotation required to match the figures

Recent Research on Mental Rotation
other stimuli (e.g., letters of alphabet)
age
practice and lack of generalization
ASL
support for the analog coding approach
8. Cognition 7e, Margaret Matlin Chapter 7 The Characteristics of Mental Images Imagery and Distance
Stephen Kosslyn
time to scan the distance between two points in a mental image
experimenter expectancy
distance in auditory images
9. Cognition 7e, Margaret Matlin Chapter 7 The Characteristics of Mental Images Imagery and Shape
Paivio (1978)
hands on imaginary clock
high-imagery vs. low-imagery participants
Shepard and Chipman (1970)
more complex shapes: U.S. states
10. Cognition 7e, Margaret Matlin Chapter 7 The Characteristics of Mental Images Imagery and Interference
Visual and Auditory Imagery
visual imagery can interfere with visual perception
auditory imagery can interfere with auditory perception
Segal and Fusella (1970)
create visual or auditory image
detect physical stimulus
people had more problems detecting the physical stimulus when the image and the signal were in the same sensory mode
11. Cognition 7e, Margaret Matlin Chapter 7 The Characteristics of Mental Images Imagery and Interference
Motor Imagery
Wexler and colleagues (1998)
joy-stick task involving rotation clockwise or counterclockwise
view geometric figure and imagine rotating it clockwise or counterclockwise
judge second figure as same or different
judgments slower when the motor movement was opposite to the mental image
