Predictions based on Cottrell's learned drive extension of Zajonc's hypothesis of social facilitation were investigated in a 2 x 2 x 2 factorial design. Sixty-four male subjects were shown a paired-associate list once or three times and then tested for recall either 2 min. or 45 min. later. Arousal at the time of learning was manipulated by the experimenter either closely observing or not observing subjects. After one learning trial, precisely the same form of Arousal X Retention Interval interaction found by Geen (1973) was obtained: observed subjects recalled fewer items at 2 min. than did unobserved subjects, while contrary to Cottrell's hypothesis, this relationship reversed at 45 min. (ps<.05). After three trials, no significant differences were found, although the means (higher for observed subjects tested at 2 min. and 45 min.) were in the direction predicted by Cottrell's hypothesis.
