Study Notes

Visual Imagery

Mental imagery involves creating images in the mind, even without the physical stimulus.
Visual imagery is "seeing" without a visual input, for example, describing your mother's face.
Mental imagery also applies to other senses, like smell, taste, and touch.

The Imagery Debate

The debate focuses on whether mental representations are spatial or propositional.
Spatial representations are like maps, with parts corresponding to specific locations.
Propositional representations use symbols to represent relationships between objects.

Visual Imagery: Shepard & Metzler (1971) Experiment

This experiment investigated mental rotation.
Participants compared two images of objects, rotating one in their head to match the other.
The time it took to compare images increased as the angle of rotation increased.
This indicated that participants were mentally rotating the objects, supporting the idea of spatial representation.

Visual Imagery: Kosslyn's Image Scanning Experiment (1980, 1994)

This experiment investigated image scanning.
Participants were asked to mentally scan between different locations in a mental image.
The time it took to scan increased as the distance between locations increased.
Results support the idea that mental imagery processes are spatially organized and like perception, there was a linear correlation between the distance and the response time.

Comparing Imagery and Perception

Imagery and perception share some similarities in terms of spatial relationships and reaction time to visual stimuli.
However, perception is automatic, while imagery requires effort. Also, perception is more stable than imagery.

Imagery and Memory

Paivio's dual-coding theory proposes that memory uses both verbal and nonverbal codes.
Concrete nouns, which evoke images, are better remembered than abstract nouns.
Visualization techniques, such as creating vivid mental images, improve memory. The organizational effect of using imagery, like the pegword method, can also enhance memory.

Imagery and the Brain

Evidence suggests that brain areas involved in visual perception (like the occipital lobe) are also active during imagery.
Neuropsychological studies (e.g., case studies on patients with brain damage) show links between brain areas and imagery functions.
Transcranial magnetic stimulation (TMS) can temporarily disrupt brain activity, providing evidence of the visual cortex's role in imagery, for example, its V1 area.

Summary of Imagery

The study of imagery addresses how we represent and process information in the absence of physical stimulation.
There are arguments concerning whether mental imagery is represented spatially or propositionally.
Studies on mental rotation, image scanning, and other experiments demonstrate strong evidence for the existence of spatial representations in the mind.
