Cognitive Development: The Theory And Practice Of Information Code Processing In Chinese Character Input

The research of Chinese character input is an important content of the basicresearch of computer technology.Chinese character input can divide into two classesof keyboard input and non-keyboard input.The research of Chinese character inputmainly laid on the ways of Chinese character input and construction of the Chinesecharacter word-stock in the past,but psychological research of Chinese characterinput is rarely involved at home and abroad.So it has very important theorysignificance and practical guide value to study the psychological principle ofinformation processing in Chinese character input.This paper starts from the qualityof Chinese characters,sees the keyboard input of Chinese characters as object,mainlyprobes the principle of information code processing in Chinese character input,analyzes the different processing trait of shape-code and sound-code in Chinesecharacter input,and investigates the influence of learning and training of informationcode processing on the development of children's cognition and language.There are five studies in this paper:Study 1:Cognitive processing of shape-code.It manly explore the cognitiveprocessing how strokes or part of Chinese character is processed into shape-code,includes two experiments:Experiment 1 is the study of shape-symbol Consciousprocessing.It starts from two experiment materials of single word and double words,analyzes subjects' Conscious processing to the basic structural unit of Chinesecharacters-the part under different tasks,consequently investigates the difference ofChinese character conscious processing and whole word discerning cognitiveprocessing.Experiment 2 is shape-code processing of Chinese character.It exploresthe cognitive activity law that shape-symbol translates into shape-code,through theway of analyzing subjects process single Chinese character of different frequencygrade,strokes number and structure style into shape-code.Study 2:Cognitive processing of sound-code.It mainly explores the inherentlaw that subjects process perceptive Chinese character note into sound-code,includestwo experiments:Experiment 3 is conscious processing of Chinese character note,itexplores subjects' conscious processing trait of Chinese character note in the condition of single character,pairs of word phrase,pairs of word non-phrase.Experiment 4 investigates that subjects translate the perceptive Chinese character noteinto sound-code.It explores the information processing trait of Chinese character notetranslated into sound-code.Study 3:The development of cognitive skill in Chinese character input.It adoptseye movement technology to compare the differences of cognitive processing ofsubjects having different input skill,while they are dealing with the information ofkey location and Chinese character input,and then investigates the trait of cognitiveskill development.It includes three experiments:Experiment 5 explores thedifferences that subjects of different skill level construct the Chinese character andreflection of the keyboard schema,seeks the law of the cognitive skill formation anddevelopment in constructing schema.Experiment 6 investigates subjects' eyemovement index when they input high-frequency word,low-frequency word andphrase,explores their differences of cognitive skill,such as Chinese characterconsciousness processing,psychological resource allocation,attention span regulation,etc.Experiment 7 analyzes eye movement index of subjects having different skill leveland input method when they input the same text material,thus probes into theconcrete difference of cognitive skills in Chinese character input.Study 4:The relation of Chinese character input and language development.Mainly investigates that practice of Chinese character input influences on thedevelopment of language ability.It includes two experiments:Through speed test ofChinese character input,literacy test and Chinese test,experiment 8 analyzes therelation of children's Chinese character input skill improvement and the raise oflanguage ability,such as literacy and reading etc,to seek the effective evidence thatthe learning of Chinese character input can promote the raise of children's languageability.Through eye movement study,experiment 9 compares the differences ofchildren having different Chinese character input skill in the picture composition,toexplore the influence of Chinese character input on children's composition ability.Study 5:The relations of Chinese character input and both stability of attentionand cognitive style.Experiment mainly investigates the influence of learning Chinesecharacter input children on stability of attention and cognitive style.Through the speed test of Chinese character input,Research passes pace of Chinese character inputtest,the test of children's stability of attention and the test of cognitive style,itsynthetically survey the relations of Chinese character input and both stability ofattention and cognitive style.We found the following results in these studies:1.The characteristic of shape-code processing that bottom-up Data-Drivenprocessing is obvious,and the characteristic of sound-code processing that top-downconcept-Driven processing is prominent,shape-code conscious processingdemonstrates the characteristic of parallel processing,and sound-code consciousnessprocessing demonstrates the characteristic of series processing;they has no phraseeffect,the response time of phrase and non-phrase has no prominent difference,butthey still have a little obvious difference,the shape-code conscious processing willnot be influenced by the frequency effect,part number effect,strokes number effectand structure style effect,and the sound-code consciousness processing is influencedby the frequency effect,part number effect.The shape-code is superior to sound-codein consciousness speed and recode rate,but the learning of sound-code puts into littlecost,and has high transfer.2.The subjects using shape-code input are superior to the ones using sound-codeinput in achievement of the new word recognition,vocabulary and reading,butneither of them has prominent difference in the total achievement of the picturecomposition.3.With the action skill are gradual proficient,the cognitive skill of Chinesecharacter input accordingly got sufficient development.No matter grasping thekeyboard schema,allocating psychological resources,or transforming input code andmatching pattern-recognition,have gone through from unskilled to skilled,from low-efficient to high-efficient.The development of cognitive skill in Chinese characterinput,children's cognitive style and stability of attention are influenced.4.If skill levels are different in Chinese character input,the development oflanguage ability will produce differences.The subjects with high level skill show thecharacteristic of more vocabulary,strong reading ability and smooth thinking.In thepicture composition,ones with high skill score are significantly superior to ones with low skill score in clarity,smooth,abundance of content,appropriateness of word,exertion of imagination,etc.
