Guttman, Gilroy, and Blake (2004) Had People View a Brief

Guttman, Gilroy, and Blake (2004) had people view a brief visual sequence in which the light and dark bars of a grating switched positions rapidly but unpredictably over time. This pattern of switches created a visual rhythm that uniquely defined each sequence. People viewed two successive visual rhythm sequences and judged whether or not the two were identical. Guttman and associates found

A) poorer performance when the visual rhythms were accompanied by an unrelated auditory rhythm.
B) poorer performance when the visual rhythms were accompanied by a related auditory rhythm.
C) better performance when the visual rhythms were accompanied by an unrelated auditory rhythm.
D) better performance when the visual rhythms were accompanied by a related auditory rhythm.
