A new theory of problem solving is presented, which embeds problem solving in the theory of action; in this theory, a problem is just a difficult action. Making this work requires a sophisticated language for-talking about plans and their execution. This language allows a broad range of types of action, and can also be used to express rules for choosing and scheduling plans. To ensure flexibility, the problem solver consists of an interpreter driven by a theorem prover which actually manipulates formulas of the language. Many examples of the use of the system six given. including an extended treatment of the world of blocks. Limitations and extensions of the system are discussed at length. It is concluded that a rule-based problem solver is necessary and feasible, but that much more work remains to be done on the underlying theory of planning and acting. 相似文献

This study examined the effects of peer group rejection and a new group's norms on 7‐ and 9‐year old children's intergroup attitudes. Children (N =82) were rejected or accepted by an initial group, then accepted by a new group that had a norm of inclusion versus exclusion towards others. Results showed that rejected compared with accepted children had a more negative attitude towards the initial group, that they were equally positive towards their new group, but that the rejected children were more negative towards an outgroup. Results also revealed an age × target group × group norm effect that indicated that the younger children's attitudes towards the three groups were more negative in the exclusion versus acceptance norm condition. The older children were also more negative towards the initial and new groups in the exclusion condition, but their more positive attitudes towards the outgroup were unaffected by the group norms. The bases of the effects of peer group rejection and group norms are discussed. 相似文献
