Prior knowledge and the desire for information.

Conducted 2 experiments to test D. Berlyne's theory that the desire for knowledge increases with the degree of conceptual conflict, and that new information serves to reduce the conflict. In Exp. I, 38 6th graders rated the extent to which they wished to explore 155 items of information. They also indicated their knowledge of these items. It was found that Ss wished mostly to experience those things about which they had a moderate amount of prior knowledge. In Exp. II, 43 11th graders indicated the extent of agreement with 24 controversial issues, and were then offered further information on each of the items. When Ss had no set attitude towards statements, they were less likely to reject additional information and more likely to accept the opportunity to receive general rather than biased information. Both studies support the authors' hypothesis that new information is sought when there is some prior knowledge and when conceptual conflict exists.
