Perception of time: delay of estimation under auditory and visual tasks with type-A measures

The perception of time is likely to be lengthened when estimates of duration are delayed rather than given immediately as reported by Vitulli and Crimmins in 1999. The present study sought boundary conditions for this robust effect. A multivariate analysis of variance showed a reliable main effect for delay of estimation, yet comparisons between auditory versus visual short-term memory tasks showed no differences in time estimations. The analysis showed weak interactions between sex and delay of estimation and between sex and delay of estimation on Jenkins Activity Survey-Job Involvement scores.
