aims of this study are threefold. The first question is: special intellectual level? Do bright children as a group present a different set of behavior problems from dull children? Do the dull children have their own characteristic problems? The second question this study attempts to answer is: Are there different and characteristic children's behavior problems dependent upon the economic group to which the child belongs? Does the rich child manifest a different set of difficulties from those manifested by the poor child? Has the poor child his own characteristic behavior deviation ? The third problem-perhaps the most important one-proposed in this study is: When these two variables, intelligence and economic level, are both operating in different directions in a group of children, which factor appears to have more weight in shaping behavior? Does a rich, dull child have problems which are characteristic of the intelligence level or the economic level of his group? Does the poor, bright child behave according to those patterns which are characteristic of his economic level or of his intellectual level?The material' studied in answering these questions was obtained from the records of the Institute for Juvenile Research in Chicago. About 700 case histories were studied. These cases yielded 1,037 different conduct disorders as diagnosed by the referring individual or organization. The sources of referral were the schools, courts, social agencies, doctors and private individuals in the community. The age range of the children was from three to eighteen years, with the median age around eleven years. Two-thirds of the children were boys. The only process of selection of cases used by the present worker was the elimination of THE Are there children's behavior deviations characteristic of any * Presented at the 1930 meeting of the American Orthopsychiatric Association.1 Dr. Herman M. Adler by his co-operation made this study possible.
The aftereffect (AE) of eye turn on autokinesis direction is usually, but not always, opposite to the inducing turn direction. During four experiments. a model predicting the aftereffect's time course and a new measure utilizing the concept of the position of random autokinetic movement (PRAKM) were developed. They showed that aftereffect direction alternates during dissipation and that its first direction is not a simple function of previous eye position, but of the process by which that position is achieved, suggesting that at least two processes are involved. In one S, versions produced the usual AE, while, after vergences, the AE was in the same direction as the inducing turn. Differential recruitment of these systems in monocular fixation could account for individual differences in the AE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
