A study was conducted to examine the hypotheses that (a) high n-Ach Ss perform better and create resources more than a group of control Ss, (b) the altruistic type of n-Ach Ss, as compared to the selfish Ss, hoard less, use resources considerately, and help the weaker partners more. A sample of thirty 3-person groups worked on two models of the Alexander's Cube Construction Test. 6 trials were given, 3 on each model. The trials were clustered into 5 blocks of 2 trials with a view to examine the effects of task experience. The possibility of resource creation was induced by providing on the experimental table a box containing relevant cubes mixed up with irrelevant ones in 1 to 3 proportion. Results confirmed the hypotheses except for the variable of inconsiderate use where, although the mean scores were in the expected direction, the difference was not significant. The findings further suggested that an altruistic set, superimposed on the n-Ach, puts incongruent demands, whereas a selfish set seems to be more matching with the n-Ach.
