A problem-solving model for teaching remedial arithmetic to handicapped young children

An operant problem-solving model was used to assist two handicapped young boys to learn the concept of number. During the initial baseline condition, with intermittent teacher-attention contingencies in a classroom setting, both boys were performing number concept tasks at about the 50% level of accuracy. The situation was changed to a one-to-one, tutor-pupil arrangement, with continuous reinforcement for correct responses. This alteration failed to increase the subjects' accuracy rates. Training was initiated in which the covert part of the response chain was made overt (e.g., attending and counting out loud) so that mediating responses could be monitored and reinforced. Once the subjects were performing at a high degree of accuracy, the reinforcers for the mediating responses were systematically eliminated and only final solution responses were reinforced. Accuracy of problem solutions remained high after training.This research was supported by the U.S. Office of Education, Division of Research, Bureau of Education for the Handicapped, Project No. 23–2030, Grant No. OEG-0-9-232030-0762(032).

Inducing cognitive development and learning: A review of short-term training experiments I. The organismic developmental approach

The author reviewed and interpreted the literature of experimental studies whose purposes were to determine rules of generation that transform a child's cognitive organization at one stage of development into that of the next, more advanced stage. The categories of the research methodology were consistent with the organismic-developmental approach, and the findings of the studies tended to support most of the hypotheses generated from this approach. Some unresolved theoretical and methodological issues were presented, and research strategies to shed light on these issues were proposed.     

Development and control of licking in the guinea pig (Cavia porcellus)

Guinea pigs were taught to lick an electronic lickometer by successive approximations brought about by a gradually receding lickerandum-liquid feeder mounted in their home cage. All Ss learned to lick and obtain their total liquid intake by tongue licking. An optimum deprivation schedule was determined, and the response was brought under schedule control comparable to that of the rat.     

Stability and Change in the Social Status of Occupations Over 21 and 42 Year Periods

Forty-two years ago, Counts (1925) surveyed the social status of occupations and found a well-defined prestige order, with banker at the top and ditch digger at the bottom. Because of changes wrought by the depression and World War II, Deeg and Paterson (1947) repeated Counts' study and found only minor relative changes in social status. Because of the extensive social and cultural changes since World War II, Counts' study was repeated again, and again only minor relative changes in the social status of occupations were found. The prestige order of the occupations surveyed is remarkably stable.     

A method for obtaining an ordered metric scale

A method is presented for collecting data which will yield a scale on which the entities are ranked in preference (ordinality), the distances between the entities on the scale are ranked (ordered metric), and all combinations of the distances are ranked (higher-ordered metric). The sources drawn upon are von Neumann and Morgenstern (9), and lattice theory. An empirical example is given in which a higher-ordered metric scale is derived.I am grateful to Professor William L. Lepley (Department of Psychology) and Professor Jack R. Tessman (Department of Physics) for their critical reading of this paper. Paul Hurst and Robert Radlow participated in many discussions on the form of measurement discussed in this paper, and assisted in collecting data. I am also grateful to Professor T. C. Benton (Department of Mathematics) for certain source materials.     

Relations Between the Development of Teaching and Theory of Mind in Early Childhood

The relations among children’s theory of mind (ToM), their understanding of the intentionality of teaching, and their own peer teaching strategies were tested. Seventy-five 3-, 4-, and 5-year-olds completed 11 ToM and understanding-of-teaching tasks. Subsequently, 30 of the children were randomly chosen to teach a peer how to play a board game, and their teaching strategies and levels of contingent teaching were recorded. There were developmental changes in the children’s understanding of teaching as an intentional activity. When teaching their peers, 3-year-olds used demonstration, whereas 4- and 5-year-olds added verbal explanations and began to adapt contingently to the learners’ changing knowledge level. Relations among ToM, understanding of teaching, and teaching level were found. The results suggest that the development of children’s teaching strategies and their contingency are closely tied to the development of ToM.     

Microcosm–Macrocosm

Much has been learned in the 20th century about the impact of covert group dynamics on the individual, the family and small group on the micro level and about institutions, communities, national and international process on a macro level. However, as we enter the new millennium this knowledge seems dwarfed by the burgeoning of knowledge about the brain and biological approaches to disturbed human behavior, casting a worrisome shadow on the future of dynamic group therapies. This article explores the impact of socio-economic-political forces on mental health delivery systems from the vantage point of group process and therapy, and raises questions about possible interventions to restore a balance between social dynamics and biology.
