- Subjects in a verbal learning study learned two equivalentlydifficult words to a criterion of one complete trial through thelist without error. In one condition, the subjects were tested witha vocal of the song “Tomorrow†from the musical Annie as backgroundmusic; in the other condition, the song and its loudness were thesame, but the music was an instrumental arrangement. The dependentvariable was trials to criterion. Conditions were counterbalancedso that half of the subjects had the instrumental condition firstand half had the vocal first. Were there differences in learningunder the two different conditions?
