Measurements On Knowledge Of Consciousness And Unconsciousness In Implicit Sequence Learning

What is knowledge representation is the focus point of researches in implicit learning. New experimental paradigm continued to be updated to measure the knowledge acquired from implicit learning. In this dissertation, we systematically review relevant research related to measure methods of consciousness, the influences on sequence representation, and related theories. With the adoption from research approach on sequence generation,we first integrate Signal Detection Theory(SDT), Process Dissociation Procedure(PDP) and segment recognition task to separate consciousness and unconsciousness.In segment recognition task,the hit means that subjects consciously or unconsciously regard an old stimulus as a new one,which is approximate to include test,P(hit)=R+A(1-R).The false alarm means that subjects unconsciously regard a new stimulus as an old one,which is approximate to exclude test,P(false alarm)= A(1-R).In the present study, we adopt three studies including seven experiments to explore knowledge of consciousness and unconsciousness acquired from implicit sequence learning.Study 1 including three experiments, verified the validity of segment recognition task(in experiment 2) and RTs(Reaction Times,RTs increased in conditions when subjects were exposed to the transfer sequence.in experiment 3),with the Response-to-stimulus interval(RSI) as independent variable and sequence generation task as criterion. This study proceeds as follow, segment recognition task is an effective tool,and RTs is only appropriate for qualitative analysis on implicitness in sequence learning, not appropriate for quantitative analysis.Study 2 including two experiments, injected the sensitivity of sequence generation task and segment recognition task on measuring the knowledge of consciousness and unconsciousness. In this study,we systematically set up the two experiments with the adoption from the procedure of Sensitivity Analysis of Technical Economy and with involvement and cognitive load as independent variables. The results show that,the sensitivity of segment recognition task is superior to that of sequence generation task.Study 3 included two experiments. Experiment 6 aimed to explore the time course of conscious process and unconscious process. The results show that, knowledge of consciousness increased and knowledge of unconsciousness decreased as the advance of study. Experiment 7 aimed to explore the retention of the knowledge acquired from implicit sequence learning. We found that,conscious knowledge was easier to forget than unconscious knowledge in the experiment with 768 trials.In a word,the validity of segment recognition task was confirmed and its sensitivity was superior to that of sequence generation task.Consciousness and unconsciousness appear to develop dynamically.
