Complexity and Cognitive Engagement in the Rorschach Task: An Eye-Tracking Study

Abstract

This study investigated whether complexity and the other related Rorschach Performance Assessment System (R-PAS) variables in the engagement and cognitive processing domain would associate with eye-tracking measures reflecting increased cognitive engagement and effort while visually scanning the Rorschach inkblots. A nonclinical sample of 71 adult volunteers were administered the Rorschach task while their eye movements were recorded using an eye tracker. Then, the average duration of fixations, the average number of fixations, the average amplitude of saccades, and the average maximum pupil size recorded during the response phase (RP) of the Rorschach administration were correlated with protocol-level, R-PAS variables located in the engagement and cognitive processing. As expected, complexity correlated, with a large effect size (r = .526, p < .01), with the number of fixations occurring during the RP of Rorschach administration. Some other variables related to complexity (e.g., Synthesis, Sy) also produced similar associations. The other eye-tracking variables under examination, however, produced weak or nonsignificant correlations.
