Learning Motivation And Feedback Delay Affect Observational Learning:An ERP Research

Learning is an important field,psychology and cognitive neuroscience studies of observational learning are also very valuable.Learn by analogy with the operating process,similar to that of helps to further understand the observational learning.The purpose of this study is to observe learning differences in neural mechanisms in the feedback processing,adopt within subjects design,experiment and experiment 2 each have 23 learners.In experiment 1,participants should not only observe learning to operate again.Experiment 2 investigate whether observational learning process and how to under the influence of feedback delay and learning motivation,and explore the neural mechanism of observational learning.The behavior of the experimental results shows that the operation and observational learning both show the rules of acquisition.Although two groups of subjects on the behavior of acquisition effect is similar,but negative feedback induced FRNS amplitude under the condition of observational learning significantly smaller than learning operation conditions.The Experiment 2 behavior data results show that the feedback delay present height does not affect the observational learning,learning motivation effect;The EEG data show that in the process of observational learning,feedback of delayed making FRN amplitude difference under the condition of rewards and punishments,short delay feedback stimulation induced FRNS significant difference under the condition of rewards and punishments and long delay feedback stimulation induced under the condition of rewards and punishments FRN difference was not significant.In order to test the reliability of the EEG data,do not distinguish between the acquisitions of data for repetitive measure analysis of variance,and found that only a significant main effect,feedback titer FRNS under the condition of negative feedback amplitude is greater.It can be induced in the process of observational learning,the same electrical components FRN operation,but the FRN in observational learning process condition is greater than learning operation conditions.In the process of observational learning,than the instant feedback delay occurs inducedFRNS smaller differences in the condition of rewards and punishments.
