Introducing the concept of neurobiological foundation of Rorschach responses using the example of Oral Dependent Language

We introduce the concept of "neurobiological foundation" of Rorschach interpretations as an extension of the concept of behavioral representation as a foundation for interpretation of R-PAS variables. Here, we propose that if there is a parallelism between the mental, verbal and perceptual behaviors occurring within the microcosm of the Rorschach task and those occurring in the external environment [behavioral foundation], then the same brain regions engaged by the test-taker when producing of a given code, should be engaged also when reproducing, in the external environment, the same psychological processes underlying that specific Rorschach code [neurobiological foundation]. To investigate this concept, we used archival, fMRI data and tested whether producing Oral Dependency Language (ODL) responses would associate with increased activation in brain regions associated with dependency-related, psychological processes. Results from a sample of 21 non-clinical volunteers partially confirmed our hypothesis, providing some support to the neurobiological foundation of the ODL code.
