Abstract (Summary)

Research has shown that positively induced mood states affect learning in individuals by providing an increase in memory span, cognitive abilities, creative problem-solving skills, and overall task performance. The impact of positive mood, though, has not been heavily incorporated into human factors research despite the fact that it has been shown to influence human performance. The goal of the present thesis was to examine the effects of positive mood induction on operator performance and subjective workload levels for different display-control mappings. Sixty four participants were assigned to one of two mood groups: positive or neutral. Humor, through watching a comedy video clip, was used to induce positive mood. Participants then performed a 4-choice stimulus-response (S-R) compatibility task with 1 of 2 mappings (compatible and mixed) under a block of trials with a time constraint or without one. Performance on the compatibility task and reports of subjective workload were examined using a 2 (Mapping condition: compatible vs. mixed) x 2 (Mood condition: positive mood vs. neutral mood) x 2 (Phase: no time constraint vs. time constraint) mixed design. Results showed none of the hypothesized effects of positive mood induction on performance and subjective workload. However, standard effects of S-R mapping and time stress on performance and reported levels of subjective workload were obtained. Implications of these findings for interface design are discussed.
