The aim of the study is to explore
the differences in executive performance profiles between second order
temperament trait configurations comprised of levels of harm avoidance (HA) and
novelty seeking (NS). The trait configurations yield the Impulsive temperament
subtype (high NS and low HA) and the Rigid temperament subtype (high HA and low
NS). From a sample of 420, participants were placed in the two apriori defined
groups according to their categorisation on NS and HA. The Impulsive subtype (n
= 121) and the Rigid subtype (n= 131) groups performance and reaction time
scores on the computerised Abstract Reasoning and Executive Functioning battery
(PennCNP) were compared.
