Conductance levels during vigilance task performance

Abstract

Using apparatus similar to the Mackworth "clock" test, 9 Ss provided conductance trends over a 2-hour session. Cluster analysis revealed 3 clusters: ascending in 4 Ss, descending in 3 Ss, and cyclical in 2 Ss. "No significant differences were found between the performances of these three clusters nor between high and low conductance groups. The results suggest, however, that higher conductance level is associated with better performance." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
