The relationship between self-reports of imagery and spatial ability

Area of Science:

• Cognitive Psychology
• Neuroscience
• Psychometrics

Background:

• A discrepancy exists between self-reported imagery vividness and spatial test performance.
• Existing measures may not fully capture the nuances of visual imagery relevant to spatial tasks.

Purpose of the Study:

• To investigate the relationship between self-reported imagery and spatial ability.
• To develop and validate a new imagery questionnaire based on established cognitive theories.
• To identify factors influencing the predictive validity of imagery measures.

Main Methods:

• Spatial ability was assessed using two spatial tests.
• Participants completed the Vividness of Visual Imagery Questionnaire (VVIQ) and a novel imagery questionnaire.
• The new questionnaire's items and ratings were informed by Kosslyn's theories of the imagery system.

Main Results:

• The new imagery questionnaire ratings significantly correlated with spatial test performance.
• VVIQ ratings did not show a significant correlation with spatial test performance.
• Imagery item type, rather than vividness alone, was a key predictor, especially for items similar to those on spatial tests.

Conclusions:

• Self-report measures of imagery can predict spatial task performance when designed appropriately.
• The type of item imagined is crucial for predicting performance, challenging models relying solely on vividness.
• Participants can accurately introspect on image properties relevant to cognitive tasks.
