A research for constraints on area of activation that determined memory development.

本研究的目的是检验扩散激活区限制假说的有效性。实验1和实验2表明，被记忆词的激活水平决定了被记忆词是否被回忆起，并且被记忆词的激活水平受到语境对激活扩散的限制;实验1和实验2表明，强语义约束条件下的被记忆词比弱语义约束条件下的被记忆词更容易被回忆起。实验3表明，与上级联想者相比，下级联想者呈现的任务型联想更容易被回忆起。实验4和实验5表明，TBR（名词或形容词）与形容词（或名词）搭配比与名词（或形容词）搭配更容易被回忆。实验6表明，当TBR同时引起前向和后向联想时，比只引起其中一个（前向或后向）联想时，TBR的回忆较少。实验7表明，在任务型联想记忆中，下级联想记忆比上级联想记忆更容易被回忆。实验8、9和10表明，TBR（名词或形容词）引起的形容词（名词）联想比引起的名词（形容词）联想更容易被回忆起来。实验11 -14表明，发展变化的制约因素的背景下，传播激活。这些结果支持CASA假说。

The purpose of the present study was to examine the validity of Constrains on Area of Spreaing Activation (CASA) hypothesis. The hypothesis assumed that the level of activation of a to-be-remembered word (TBR) determined whether TBR was recalled or not and that the level of activation of TBR was maintained by constraints of contexts on spreading activation.Exp.1 and 2 indicated that TBR in the context of strong semantic constraint to TBR was more recalled than TBR in the context of weak one. Exp.3 showed that TBR presented with subordinate associate was more recalled than it did with superordinate one. Exp.4 and 5 indicated that TBR (noun or adjective) paired with a adjective (or noun) associate was more recalled than it with a noun (or adjective) one. Exp.6 showed that TBR was less recalled when it elicited both forward and backward associates than when it elicited only either (forward or backward) one. Exp.7 showed that TBR elicited the subordinate associate was more recalled than it did the superordinate one. Exp.8,9 and 10 indicated that TBR (noun or adjective) elicited a adjective (or noun) associate was more recalled than it did a noun (or adjective) one. Exp.11-14 indicated that developmental changes in constraints of contexts on spreading activation. These results supported the CASA hypothesis.
