Comparing self-report and mental chronometry measures of motor imagery ability

Abstract

The present study investigated the relationship between two of the most common measures of motor imagery ability, self-report ratings, and chronometric assessment. This was done for three types of imagery modalities: external visual imagery (EVI), internal visual imagery (IVI), and kinesthetic imagery (KI). Measures of imagery ability (i.e. self-report and mental chronometry) were also compared across skill levels. Participants (N = 198) completed the Movement Imagery Questionnaire-3 (MIQ-3) to generate self-report ratings. Chronometric assessment was obtained by recording the duration of each MIQ-3 movement imaged and physically performed and then calculating a discrepancy score. There were no significant correlations between self-report and mental chronometry for any of the three motor imagery types (p > .05). When assessing the different types of motor imagery ability using self-report ratings, elite athletes had significantly higher KI than IVI, which was in turn significantly higher than EVI (p < .05). When assessing motor imagery ability using mental chronometry, there were no significant differences in imagery type (p > .05). Findings suggest both measures address different components of MI quality and should be used together to obtain a more comprehensive assessment of motor imagery ability.
