Abstract

This study examined whether baseline PPI levels reflect individual efficiency in tasks associated with routine versus supervisory attentional systems (SAS). PPI and neuropsychological data were collected from 30 healthy male subjects. High PPI was associated with shorter movement times on the 5-choice Reaction Time and shorter Subsequent Thinking Times in the Stockings of Cambridge test. These data suggest that high-PPI status reflects greater efficiency in tasks that engage SAS.
