Experimental Study On Mechanism Of JOL

JOL is an important aspect of metamemory monitoring and control. As one of prospective monitories, it reflects predictions of one's memory. Exploring the mechanism of JOL of the undergraduate students not only provides lots of data to our country's study of JOL, but also reveals one's learning and memory, what's more, the control of one's learning and memory, which can provides theoretical base to the people of more effective learning and memory .So, the study of JOL is very valuable and useful.The study of JOL is more about its mechanism and accuracy. The researchers studied its mechanism, from different aspects, using different experimental designs and materials, and suggested many different theories, as follows: target retrieve ability hypothesis, cue familiarity hypothesis. Access ability hypothesis and competition hypothesis. At present various hypothesis fail to come to any agreement .We can not ascertain which hypothesis is correct. On the basis of analysis on these theories, we think:(1) These theories points at the role of clue and target in the process of JOL, or the main decisive factor of JOL is cue familiarity or target retrieve ability, or both are important;(2) The study of the mechanism of JOL mostly depends on meaningless materials. So many studies didn't pay attention to two different materials before;(3)The study carried out using one of types of JOL and studied the mechanism of JOL. This phenomenon looks like completely made mechanism of two types same, this question is to be studied. Try to carry out verification on this several kinds theory hypotheses, in order that we can provide new evidences to these theories and new clues to the mechanism of JOL. Study originally on summing up the basis studying at home and abroad in connection with this aspects, using classical experimental design (learn-judgement-recall), coming to try to verify the hypothesis of JOL by two experiments. In this study the two experiments both used two factors repeated design, controlling the types of pairs associated words between clues and targets, in terms of the predictions of the past study of JOL. Several types of pairs associated words will support the different hypothesis: If the JOL of (1) and (2) are equal, the JOL of (2) is higher than (3) and (4),what's more, (3)and(4) are the same, this will support the cue familiarity hypothesis; If the JOL of type (1) is higher than type (2), the JOL of type (2) is equal to (4),and the JOL of type (2) and (4) are lower than type(3),this support target retrieve ability hypothesis; The JOL of (1) is higher than type(2), the JOL of type (2) is equal to (3),it divides two kinds: If the JOL of type (2) and (3) are lower than type (4),this will support competition hypothesis; If type (2) and (3) are higher than type (4),this will support accessibilty hypothesis. In experiment 1 ,we studied the effects of materials and the types of pairs associated words of the mechanism of immediate JOL; In experiment 2 ,we studied the mechanism of delayed JOL and did further research of experiment 1 .In both experiments we used the same materials and designs,4(types of words)×2( material types). On the bases of the 2 experiments ,the results showed that:1. Using meaningful words pairs and meaningless ones as our materials, adopting 4 types words pairs in the proactive inhibition experimental design exists significant interference effect. In this way, it can control the cue familiarity and target retrievablity.2. Sngle target retrievablity hypothesis or cue familiarity hypothesis is not scientific. Judgement and memory of A-B,A-CandA-B,D-B conditions showed no difference. The cue and the target are all playing certain role in JOL. Under identical experimental controlling, the cue and target affected JOL in the similar way.3. The JOL and recall of meaningful word pairs are significantly higher than meaningless ones both types of JOL.4. Immediate JOL and delayed JOL have the same mechanism.
