Direct comparisons of perception and mental imagery are difficult to interpret. Current research methods lack sufficient operational definitions, limiting causal claims about imagery effects.

Area of Science:

Cognitive Psychology
Psychology of Perception

Background:

Comparing perceptual performance with mental imagery reports is methodologically challenging.
Previous research has not adequately established the conditions for valid comparisons.

Purpose of the Study:

To critically evaluate the interpretability of studies comparing perceptual performance and imagery.
To identify limitations in current experimental designs for studying mental imagery.

Main Methods:

Analysis of experimental constraints and operational definitions in imagery research.
Critique of the use of imagery instructions and introspective reports.

Main Results:

Studies comparing perception and imagery are often uninterpretable due to poorly understood phenomena and insufficient experimental control.

Imagery instructions lack the rigor of operational definitions, making causal links difficult to establish.

Conclusions:

The validity of direct comparisons between perception and imagery is questionable.
Future research requires clearer operational definitions and experimental designs to establish causal relationships in mental imagery.
