Abstract
Previous research has shown a positive correlation between working memory and performance
on a measure of risky decision making, the Iowa Gambling Task (IGT). However, to date, no one
has manipulated the presence of music and increased working memory load during this task. The
present study sought to see how these factors influence decision making. In Part One, 90
undergraduate students (44 females, mean age 19.29) were randomly assigned to complete
several computerized decision making tasks with classical, rock, or no music playing passively
in the background. Results indicated a trend towards those listening to music, regardless of the
type of music, were less risky on one of the tasks than those in the non-music condition. In Part
Two, 90 undergraduate students (54 females, mean age 18.57) were randomly assigned to one of
three working memory load conditions while simultaneously completing the same series of
decision making tasks: a) counting a particular word in rock songs; b) counting tempo changes in
classical songs; or c) completing working memory tasks. Results indicated that individuals
listening to rock music were riskier on only one of the decision making tasks. Implications for
this study include the need to reduce distractions and multi-tasking while making difficult
decisions in everyday life.
