Abstract

In the present descriptive study, short-term memory performance was examined in nine individuals with closed head injury and nine controls matched for age, gender, and education level. Subjects were asked to verbally recall selected words from a list of six words that were visually presented to them. Task stimuli were shown under two conditions (noise vs. no noise) and three modes of presentation (read-only, read-hear, and read-verbalize). A three-way ANOVA (Group x Noise x Mode) showed a significant main effect between groups, with the control group recalling a greater number of correct words. No significant interactions were seen for either noise condition or mode of presentation in either group. Results were discussed with regard to the role rehearsal in short-term memory.
