48 Ss were given 20 control trials and 10 trials under competitive conditions on a number facility test (NF). After the administration of NF Ss were divided into 2 groups on the basis of their n-Ach score on the Edwards Personal Preference Schedule. The 24 highest Ss on n Ach were assigned to the high n-Ach group, the other 24 being designated the low n-Ach group. The NF performance of the high group was consistently above that of the low n-Ach group, although this difference was not significant under either control or competitive conditions. A significant learning effect was found over trials. The implications are discussed.
