We investigate the association between temperament and character dimensions, on the one hand,

and computerised neuropsychological test performance, on the other hand. Temperament and

character dimensions were operationalised as scores on the subscales of the Temperament and

Character Inventory (TCI), a 240-item measure that is based on the psychobiological theory of

personality. Neuropsychological outcomes were measured on six computerised tests of executive

functioning and abstract reasoning from the University of Pennsylvania Computerised Neuropsychological

Test Battery (PennCNP). The executive and abstract reasoning tasks included a test of

Motor Praxis (MPRAXIS), the Penn Abstraction, Inhibition and Working Memory Task (AIM), the

Letter-N-Back (LNB2), the Penn Conditional Exclusion Task (PCET), the Penn Short Logical Reasoning

Task (SPVRT) and the Short Ravenís Progressive Matrices (SRAVEN). Results from this

exploratory study yielded significant associations between neuropsychological performance and

temperament and character traits. The temperament traits of Harm Avoidance and Reward Dependence

were positively correlated with reaction time on the AIM and the SPVRT. The character

dimension of Self-Transcendence was significantly associated with performance accuracy on the AIM

and the temperament dimension of Novelty Seeking was inversely related to performance accuracy

on the LNB2. These results confirm the importance of addressing the temperament and character

correlates of neuropsychological performance in both clinical and non-clinical studies.
