The Similarity Of The Associated Processing And Scene Encoding Selective Inhibition

Directed forgetting announces that mechanism of our inhibition can inhibit irrelevant information effectively and intentionally, but the failure of selective inhibition ran counter to this.We thought that the failure of selective inhibition was because that subjects could not segregate the TBR (the items to be remembered)and TBF(the items to be forgotten).If segregation of items did not accomplish, the process of inhibition would lead to all the items to be inhibited.The suppose of the whole experiments were the failure of segregation between TBR and TBF caused spread of inhibition. The goal of our experiments was to explore generated the failure. Results are followed as such:1 .The substance of selective inhibition was that if the goal was inhibited, the irrelevant information was whether inhibited or not automatically.2.The failure of selective inhibition was because that the information of goal and irrelevant information were not segregated. The reasons of the items lacking segregation were Relational process and similarity of situational factor in encoding.3. Relational process made the items establish relation and form a whole,so that the irrelevant information was also inhibited when the information of goal was inhibited.4.Though the two kinds of items did not build relation, the irrelevant information was inhibited when they only had the similarity of situational factor in encoding.5.The mechanism of segregating items was not the same that of Directed forgetting.6.There was not only spreading Activation but also spread of inhibition. Spread of inhibition occurred in concepts which had semantic relation directly and had relation that was established arbitrarily by subjects. Besides, if concepts were encoded in similar situational factor, spread of inhibition also generated.
