Study Notes
Mental Imagery
- Mental imagery is the mental representation of things that cannot be currently sensed, and can be in any modality (hearing, smell, taste, touch, vision).
- Visual imagery is the most reported in diary studies and the most studied type of imagery in humans.
Representations of Information
- Information can be represented in two ways: symbolic representations (e.g., words) and analogic representations (e.g., pictures).
- Symbolic representations use arbitrary symbols to represent features of objects, while analogic representations preserve main perceptual features of objects and their transformations.
Theories of Mental Imagery
- Dual code theory (Paivio, 1969, 1971) proposes that humans use both symbolic and analogic codes to represent information.
- Propositional theory (e.g., Anderson and Bower, 1973; Pylyshyn, 1973, 1984) suggests that propositions (mentalese) represent the deep meaning of objects and their relationships.
- Functional equivalence hypothesis (e.g., Jolicoeur and Kosslyn, 1985; Peterson et al., 1992) proposes that processes for constructing and manipulating mental images are similar to those used in visual perception.
Mental Imagery and Cognition
- Mental imagery is useful for answering queries, solving problems, making predictions, and planning actions.
- Mental imagery can be used to construct and manipulate mental maps, which are derived from navigating an environment and actively constructed from partial information.
Mental Maps and Navigation
- Cognitive maps can be affected by propositions, inferences, and conceptual knowledge.
- Distance estimation from cognitive maps is affected by the density of landmarks in a map and the presence of routes.
- Relative position is affected by heuristics, such as the presence of routes.
Mental Rotations
- Mental rotations are similar to visually observing physical rotations of objects.
- Reaction time (RT) is linearly related to the degree of rotation.
- Mental rotations involve operations on mental images that resemble what we would see by moving towards or away from physical objects in the real world.
Image Scaling and Scanning
- Mental images can be scaled up or down, similar to visually observing physical objects.
- Details of large objects are seen first, and to see details of small objects, we need to zoom in, which can result in a loss of information about large objects.
- Image scanning involves zooming in and out to see details of objects.
