学习困难儿童智力结构及其与心理语言、视动能力关系的研究

IQ Structure, Psycholinguistic and Visual-motor Abilities Study on Children Learning Disability TONG Fang Directed by professor Zhu Liqi (Developmental and educational psychology) ABSTRACT Objective To comprehensive analyze the IQ structures, and relationships among IQ, psychometric characteristics and visual-motor integration on children disability. At same time, to probe into the family factors that influenced IQ, psycholinguistic abilities and behavior of LD children. Method (1) Downloading the papers on children learning disability from www.cqvip.com and www.wanfangdata.com, in which, the articles were collected by key words from 1985 to 2005. To conduct meta-analysis on IQ construction, compare the case group and the control group, including full IQ, verbal and practice IQ. (2) Designed with model compared and self-compared, 59 diagnosed learning disability children, tested themes with WISC, ITPA and Berry’s VMI. WISC included 10 items, 5 of which subtotal to verbal and practice IQ respectively. IPTA included 10 items, too, 5 process of which subtotal to auditory and visual perception. The first 3 items shared representation level, the other 2 of that shared automatic level.VMI had one score. Analyzed factors and levels with description and Pearson Correlation. To probe to linguistic internal alternately functions of LD children, and compare the scores of groups in different IQ. (3) Analyzed the perspective questionnaire filled by parents. Early development facts compared with model groups. Factors relationships analyzed with Kendall correlation, KOM and Bartlett’s test of sphericity, Promax Rotation. Results: (1) There have been 319 papers related with LD, in which 36 with IQ and 14 valid reports have been analyzed by Meta. FIQ’s 95%CI (confidence interval) is 2.418 ~ 0.172, VIQ between the difficulty and non- difficulty group. C-WISC-R reports were 10 papers, of which, 95%CI of FIQ is 2.424 ~ 0.676, of VIQ is 2.314 ~ 1.196, of PIQ is 2.176 ~ 0.176. The VIQ comparing the PIQ, 95%CI is 1.1 ~ -0.07 in difficulty group and 0.5 ~ -0.0046 in non-difficult group. Nevertheless, in the other 4 tests, FIQ’s 95%CI is 2.00 ~ -0.818 between LD and NLD. (2) Children psycholinguistic abilities had strong relation with Berry’s VMI test excluding auditory reception, and with perceptive factor of intelligence excluding verbal expression. Auditory reception and visual closure had strong relation with FIQ and PIQ. Grammatic closure, visual association and manual expression had strong relation with concept factor. The representational and automatic levels are depended on integration of auditory and visual procession. Lower verbal expression (VE) let to lower expression process and low scores on representational level. Lower visual sequential memory (VSM) let to lower memory process and influenced automatic level. Groups compared by IQ 90 show that LD children with under IQ 90 had lower scores on items of IPTA than with up IQ 90 excluded verbal expression. It was proved that IQ administrated the linguistic ability. Nevertheless, general abilities deficiency didn’t show influencing on the types of the perceptive delay. There was mutual function among linguistic ability on LD children. Auditory and visual level are overlapped each other. Not only show higher Decoding and lower Encoding on Auditory perception, lower Decoding and higher Encoding on Visual perception, in representation, but also higher Sequential remember, lower Closure on Audition, and lower Sequential member, higher Closure on Vision, in Automation. Nevertheless, there was no different between Representational and Automatic level, which may be the relationship of parallel or evolution. (3) Major family factors were father’s education, occupation. Lower auditory perception related to unconcerned, lower visual perception related to premature delivery and written slowly. Threatened–abortion, childbirth-suffocated were known as influencing children’s IQ and later linguistic abilities. It wasn’t shown that dosage relationship with the types of perceptive delay. Conclusion: (1) The FIQ, VIQ and PIQ of Children with LD is lower than that of NLD group. There is no significantly different between VIQ and PIQ in LD and NLD groups. (2) The objectives of ITPA and WISC tests are differently. The psycholinguistic abilities had strong relation with perceptive factor and VMI. Some facts of IPTA related with FIQ. IQ had strong administration on linguistic abilities. There was mutual function among linguistic internal abilities. (3) Family facts on IQ and psycholinguistic abilities were Father’s education, abnormal pregnant and abortion. It would be pre-show development delay in early period.

问题之间共性关系的意识水平对平面几何解题迁移的影响

Transfer of learning is one of the major concepts in educational psychology. As cognitive psychology develops, many researchers have found that transfer plays an important part in problem solving, and the awareness of the similarity of related problems is important in transfer. So they become more interested in researching the problem of transfer. But in the literature of transfer research, it has been found that many researchers do not hold identical conclusions about the influence of awareness of related problems during problem solving transfer. This dissertation is written on the basic of much of sub-research work, such as looking up literature concerning transfer of problem solving research, comparing the results of research work done recently and experimental researches. The author of this dissertation takes middle school students as subjects, geometry as materials, and adopts factorial design in his experiments. The influence of awareness of related problems on problem solving transfer is examined from three dimensions which are the degree of difficulty of transfer problems, the level of awareness of related problems and the characteristics of subjects themselves. Five conclusions have been made after the experimental research: (1) During the process of geometry problem solving, the level of awareness of related problems is one of the major factors that influence the effect of problem solving transfer. (2) Either more difficult or more easy of the transfer problems will hinder the influence of awareness of related problems during problem solving transfer, and the degree of difficulty of the transfer problems have interactions with the level of awareness of related problems in affecting transfer. (3) During geometry problems solving transfer, the level of awareness of related problems has interactions with the degree of student achievement. Compared with the students who have lower achievement, the influence of the level of the awareness is bigger in the students who have higher achievement. (4) There is positive correlation between geometry achievement and reasoning ability of the middle school students. The student who has higher reasoning ability has higher geometry achievement, while the level of awareness is raised, the transfer achievement of both can be raised significantly. (5) There is positive correlation between geometry achievement and cognitive style of the middle school students. The student who has independent field tendency of cognitive style has higher geometry achievement, while the level of awareness is raised, the transfer achievement of both can be raised significantly. At the end of the dissertation, the researcher offers two proposals concerning Geometry teaching on the basis of the research findings.

通过对心理学期刊的几项统计分析看我国十年来儿童发展教育心理学研究状况与动向

In this study, bibliometric method was usded in the investigation of 2274 papers concerning child developmental and educational psychology, which were published during the ten years of 1979-1988, in 14 psychological journals and 97 other scientific journals. According to the quantitative and qualitative analyses, the results are as follows: 1979-1988 saw the rapid development and prosperous period in China's child developmental and educational psychology, During which more papers were published and more fields couched than in the psvious thirty years. The number of literature publications increased and went to the peak in 1983 and 1984, and came down since 1985. The trend was found to result from the decrease in popular science introductions of psychology, which reflected that a heat of psychology had appeared in 1983 and started to cool in 1985. At the mean time, the number of research reports had been holding a steady increase by 1987 and decreased obviously in 1988, especially in the fields of cognitive and social development. There could be several possible explanations of this phenonemon: Piagetian studies are becoming fewer and the eakening of Piaget's influence might predict a period of standstill in the field of developmental psychology in China; As researches become more and more difficult, researchers have turned to be more cautious in lay out their reports; the cutdown of fees and staff could also be one of reasons for less publication in 1988. As the factors mentioned above still exist and their influences last, the number of papers are not expected to increase in the near future. The field of thinking and menory is closely connected with that of artificial intelligence. The downhill situations in these two fileds should be taken seriously. 2. The types of research work are divided on the bases of their problem raising. The trends show that the deepening studies, which represent a comaratively higher level of exploration, are waving fewer, while repeated studies and creative studies are becoming more as the years go along. This fact is worth being further analysed. Big progress could be seen from research methods. The methods currently used are mainly experiment, psychological measurement and assessment, and theoretical reasoning. There is a rapid increase of research by using scales. Wechsler Intelligence Scale for Children, Binet Scale and Baley Scale have been revised andstandardized. Chinese researchers have also developed several good scales of their own, some of which are valuable and need to be standardized. In the papers investigated, the amount of citation is significantly lower than the world average level as well as the average citation number of whole China's scientific literature. Among the papers cited, most are of Chinese and English languages, and only a small rate were published in resently five years. The renewal of literature cited seems to stay at a low level in the ten years. Tremendous work could be reflected by the number of subjects used the research work in those ten years: 362665. A lot of studies piled on the period of 4-16 year olds. Compared with the previous thirty years, the age range was much enlarged and there were quite a few studies about preschool, school and adolescent periods. The study of newborn of 0-3 has been a weak point so far and it is a field to which chinese developmental psychologists should pay more attention. The progress in using statistics is one of the most obvious part in the development in the research work of child developmental and educational psychology. The one tendency that should be awared and avoid is to put the cart before the horse: seeking for more sophisticated statistic method while neglecting the meanings of research problems. 3. Citation analysis was used in selecting scholars who had great influence in the field of child developmental and educational psychology. Among the often cited and famous scholars, 31 are Chinese researchers and 12 are Western psychologists. The authoritative journal for child developmental psychology and educational psychology is Acta Psychologica Sinica.
