Children often perseverate, repeating prior behaviors when inappropriate. This work tested the roles of verbal labels and stimulus novelty in such perseveration. Three-year-old children sorted cards by one rule and were then instructed to switch to a second rule. In a basic condition, cards had familiar shapes and colors and both rules were stated explicitly. In an uninformative-label condition, cards had familiar shapes and colors, but the first rule was not stated explicitly. In a novel-stimuli condition, both rules were stated explicitly but stimuli were novel on the first sorting dimension. More children switched to the second rule in the uninformative-label and novel-stimuli conditions than in the basic condition. Implications for theories of cognitive flexibility are discussed. 相似文献

基于SLEUTH模型的沈阳-抚顺都市区城市规划 总被引：2，自引：0，他引：2
利用SLEUTH模型,在3种规划预案下研究沈阳-抚顺都市区城市规划。结果表明,低生态保护的城市增长预案导致了城市快速扩张和农田、林地等其他景观类型面积迅速减少.严格的生态保护规划预案虽然能很好地保持聚集的城市增长格局,减少对其他景观的侵占,但限制了城市增长速度,与区域经济发展现状相矛盾.如果扩散的城市增长格局能得到进一步的控制,适当生态保护的城市增长预案将是沈阳-抚顺都市区未来发展的推荐预案. 相似文献
