Attribution of responsibility in a coin-flipping task

Female students predicted the outcome of a tossed coin (heads or tails) for each trial. After they had tossed a coin and observed the outcome for 10 trials, they made an attribution of responsibility for the number of successful predictions which they had made. The attribution of responsibility was made on a continuum varying from complete personal attribution to complete situational attribution. Contrary to the self-enhancement hypothesis, the number of successful predictions did not affect their attribution of responsibility. Both participants and observers made similar attributions which were mainly situational.
