The Effect Of Massed And Spaced Learning On The Recognition Of Face: A ERPs Study

Ebbinghaus puts forward effective means to prevent forgetting is to repeat in time.Many researchers conducted follow-up studies, repetition and at follows the law of many.Scattered among them, the learning effect is a stable exists in large learning material, form of learning and memory in memory.Distributed learning effect is refers to under the repetitions of the same, scattered repetitive learning program than focused learning project is a good memory. This research attempts to study in unfamiliar faces, whether learning effect remains stable, scattered learning effects of cognitive processing mechanism, and the repetition interval and me-mory effect of the relationship between(inverted U-shaped or linear relationship).This research adopts by 2 × 4 subjects in experimental design. Independent variables within a group for variables, two levels was first introduced, repeated(repeat number:), the independent variables were variable in the group, four levels(twice the gap between the present quantity respectively: lag1 = 0, lag = 1, lag = 6,lag = 12), presents four conditions of sequence is completely random design. The mission of the subjects is a face image is presented for sex(male/female),recognition in 3 minutes, judgment task for sex. First of all, the selection of lag = 0and lag = 1 project for concentrated study, lag = 6 and lag = 12 project for distributed learning, behavior and erg level of comparison, to explore the cognitive neural mechanisms of scattered learning effects. Secondly, based on the four kinds of repetition interval under the condition of EEG and behavior data analysis, to examine repetition interval and dispersion of the relationship between learning.Through the analysis of the behavior and erg data, this study the following conclusions:(1) Scattered advantages exist in the process of learning in unfamiliar faces, is about the learning effect in the validation.(2) Material repeat interval changes affect memory. Materials under the conditions of different repetition present interval significant differences in memory performance, memory performance with the increase of the stimulus repetition present interval shows ascendant trend, concrete embodiment in free recall rate,recognition test shot and to identify service index.(3) Study in priming effect in the behavioral level, it embodied in the process of learning materials present on the reaction of two times. In neural activity level strongrepetitive nerve inhibition effect of differences. Specifically, relative to the repetition interval short, long recurrence interval reduced the materials of repetitive nerve when in his second start, stronger activation at the top of the frontal area. Suggesting that scattered learning effect could start by reducing repetitive nerve in the learning process, make the material in the second presents the corresponding brain regions activated degree increase, thereby increase sing the memory performance. This research results to some extent, support the short-term perception start hypothesis.(4) EEG analysis results, repetition interval variability affect memory neural-al mechanisms, different repetition interval linear mode exists in the level of neural activation, embodied in VPP, N400 associated with memory coding and LPC on the electrical components.
