Neuroimaging Studies of Specific Rorschach Variables

This chapter reviews neuroimaging research exploring the relationships between performance on the Rorschach and brain structure and function. It focuses on unique perception ( FQu, FQ– ), human movement ( M ), and color-determined responses ( WSumC ). Drawing on studies using magnetic resonance imaging, functional magnetic resonance imaging, electroencephalography, and repetitive transcranial magnetic stimulation, the chapter links these variables to brain regions involved in emotional regulation, perceptual accuracy, embodied simulation and mentalization, and cognitive-affective integration. Findings suggest that FQ responses are associated with amygdalar modulation of perceptual processes, M responses with activation of the mirror neuron system, and WSumC with left-hemisphere-mediated affective processing and the integration of affect into decision-making. The chapter discusses implications for understanding the perceptual, cognitive, and emotional dimensions of Rorschach responding and highlights the test's neuropsychological relevance in assessing psychological resources and adaptive functioning. These insights help clarify why M and WSumC are empirically supported indicators of mentalization, empathy, and executive functioning and how their absence or poor quality may reflect neurocognitive impairment. Clinical psychologists and neuropsychologists using the Comprehensive System (CS), CS-Revised (CSR), or Rorschach Performance Assessment System (R-PAS) will find this chapter especially valuable for integrating neuroscience into Rorschach assessment.
