%X Based on the studies of Stasser and Larson, this study investigated the effects of task difficulty, decision training and the role of group leaders on the quali ty of decision-making by groups with laboratory experiments. In this study, the 3-person group was asked to decide which one among 3 candidates was best suitab le for the position of student body president or which one among 6 candidates wa s best suitable for the position of university English teacher. The results show ed: (1) The information sampling model was partly verified, and the personal pre ference was the mediated factor affecting the decision making of groups, but onl y when the task was less complex was the model correct; (2) Group leader managed and colligated already-pooled information by repeating information and question ing, but such a group structure had no major effect on the information sampling and its effect was shown only by combining with decision training and task compl exity; (3) Training of the strategy planning and information vigilance enhanced the proportion of unshared information discussed. But only when task complexity was low or moderate did the effect appear, and it happened only at the beginning of discussion, and had impact on personal preference of members' before discuss ion; (4) There was an interaction between the effects of a group leader and deci sion training, i.e., the leader could prompt information sampling of a group in the decision-making training condition, and the effect of decision-making traini ng was more prominent in the condition of having a group leader. These two f actors were both affected by task complexity.
