Test length and cognitive fatigue: an empirical examination of effects on performance and test-taker reactions.

Full Abstract

Person and situational determinants of cognitive ability test performance and subjective reactions were examined in the context of tests with different time-on-task requirements. Two hundred thirty-nine first-year university students participated in a within-participant experiment, with completely counterbalanced treatment conditions and test forms. Participants completed three test sessions of different length: (a) a standard-length SAT test battery (total time 4(1/2) hr), (b) a shorter SAT test battery (total time 3(1/2) hr), and (c) a longer SAT test battery (total time 5(1/2) hr). Consistent with expectations, subjective fatigue increased with increasing time-on-task. However, mean performance increased in the longer test length conditions, compared with the shorter test length condition. Individual differences in personality/interest/motivation trait complexes were found to have greater power than the test-length situations for predicting subjective cognitive fatigue before, during, and at the end of each test session. The relative contributions of traits and time-on-task for cognitive fatigue are discussed, along with implications for research and practice.
