Influence Of Semantic Consistency And Visual Complexity On Spoken Word Recognition In 5-6 Year Old Children: Evidence From Eye Movement Research

Oral vocabulary recognition is an important cornerstone for successful oral comprehension.There are few studies on the effects of visual competition words and semantic competition words in the recognition of infant oral vocabulary.In the face of this situation,children aged 5-6 years were selected as subjects,eye movement techniques were adopted,and visual-context was used.Paradigm to study the different effects of visual information and semantic information on oral word recognition.In the specific experimental study,the young children were asked to find the corresponding words from the pictures displayed on the screen while they heard the words.For example,in experiment one,presents the peanuts,hearing and the matching 4 pictures are peanuts(target),tomato(semantic word competition),truck(visual competition)and dogs(not interfere with the word),in the experiments,participants heard through headphones peanuts,screen render target word,the word visual competition,competition semantic not interfere with the word of the images,eye movement instrument will automatically track the back of the eye movement track.The auditory words presented in Experiment 1 were highly familiar words,and the auditory stimuli in Experiment 2 were contextual information with relatively high restrictiveness.The eye movement indicators such as the time of first entering the area of interest,the first fixation point of interest in the area of interest,the total fixation time in the area of interest,the number of fixations,and the total visit time were selected.The results of experiment 1 are:(1)On the eye movement index for the first entry time,the competition words containing semantic and visual information did not show differences;(2)there is no difference in the fixation time of the first fixation point of semantic competition words and visual competition words;(3)the total fixation time and total visit time of semantic competition words and non-interference words are more than that of visual competition;(4)semantic competition words and non-interference words have more fixation points than visual competition words.The experimental results show that(1)the processing of infant oral vocabulary supports the distributed queue model;(2)the visual and semantic competition words all interfere with the processing of infant oral language,but the effects are not the same and show a clear semantic bias;(3)oral recognition activates visual and semantic information in the early stage and only activates semantic information in the late stage;(4)there are significant differencesbetween the total fixation time and the total access time of the non-interference words and the visual competition words,and the total fixation time and total visit time of the non-interference words are more than the visual competition words;(5)The differences between the number of fixations and semantic competition words and visual competition words are very significant,and the number of fixation points of visual competition words is obviously less;in addition,there was a significant difference in the number of fixation points between unrelated interference words and visual competition words,and the number of fixation points of unrelated interference words was more than that of visual competition.The experimental results indicate that(1)children's oral recognition supports the ideas of DCM model.(2)both visual information and semantic information can affect children's oral vocabulary recognition,but the degree of influence is different and there is a semantic bias.(3)visual information received in the early identification of activation,semantic information in early and late have been activated,and(4)whether the same level or different levels of semantic information,will influence the process of spoken word recognition.
