The Influence Of Familiarity On Visual Implicit Learning And Auditory Implicit Learning

In order to explore the influence of familiarity on implicit learning in different sensory channels,270 college students were selected as subjects.Using the classical limited state artificial grammar paradigm of implicit learning,three experiments were set up according to different familiarity levels: high familiarity,low familiarity and medium familiarity.At the same time,more realistic experiments were added in each experiment Finally,according to the experimental results,the familiarity effect and psychological mechanism of implicit learning in visual channel and auditory channel are analyzed.The results finded that:(1)under different familiarity conditions,the acquisition effect of implicit learning in different sensory channels was different: under high familiarity conditions,visual implicit learning performance was significantly better than that of auditory implicit learning without prosodic information;under low and medium familiarity conditions,auditory implicit learning performance with prosodic information was significantly better than that of visual implicit learning performance;(2)Under the condition of full of prosodic information,the auditory implicit learning under the condition of low familiarity and high familiarity was significantly better than that under the condition of medium familiarity.The results showed that:(1)with the help of prosodic information,it can also produce significant auditory implicit learning effect under the condition of low familiarity.Based on the fact that infants can acquire completely unfamiliar mother tongue efficiently through auditory channels,we speculate that the acquisition of infant mother tongue is based on the grammar acquisition mode of prosodic information processing;(2)under different familiarity conditions,the psychological mechanism of brain processing may be different: to deal with materials with high and low familiarity in the way of overall processing;to deal with materials with low familiarity in the way of partial processing;(3)According to the limited theory of psychological resources and aphasia language processing model,we think that there are differences in brain processing paths when the subjects are engaged in implicit learning of materials with different familiarity: there are two processing paths for materials with high and medium familiarity;there is only one processing path for materials with low familiarity.
