New problems and results in behavior therapy

What is presently observed is not only a rapid increase in the number of publications, but also a major change in the theoretical principles of behavior therapy. The former onesidedness of a form of behavior therapy theoretically substantiated by classical conditioning only may be regarded as having been completely overcome. For example, this is evident from new approaches to behavior diagnosis as an essential prerequisite of differentiated therapy planning. Recent concepts of the theoretical substantiation of the effectiveness of behavior therapy lead to an increasing consideration of both cognitive and motivational aspects and also take into account the complexity of the patient's social relations. This, in turn, results in the availability of a wide range of indication-specific methods of behavior therapy.     

The influence of training for the atomistic schema on the development of the density concept among gifted and nongifted children

The present study was conducted for two purposes. The first was to test the relations between the schema of atomism and the concept of density, and to examine the effects of Piagetian stage and M-capacity on these relations. This was accomplished by giving training for the schema of atomism to children at different stages and with varying M- capacities. The second purpose was to test the effects of age (9–10 versus 11–12 years) and IQ (gifted versus nongified children) as variables that would influence the outcome of training. A total of 120 children were tested. The findings were that the effects of the training and the IQ variables were significant while the effect of the age variable was not. When stage and M-capacity were covaried the effects of training and IQ remained significant. Implications for issues of developmental theory and educational practice are discussed.     

An experiment promoting interdisciplinary applied human development: The University of Pittsburgh model

The University of Pittsburgh Office of Child Development is an unusual university facilitative and administrative unit that promotes, funds, plans, implements, manages, and conducts interdisciplinary applied education, research, service demonstration, program evaluation, and policy projects pertaining to children, youth, and families. In the 9+ years of its existence, its soft-money budget has grown more than 34 times, its number of employees has increased 27-fold, and it has played a major role $75 million worth of collaborative projects. This article describes the Office's rationale, structure, purposes, principles of operation, projects, evaluation, and positive and negative factors in its development so that others may benefit from this case-study experiment in interdisciplinary applied human development programming.     

Before and After the German Reunification: Changes in Observers' Commentaries on Achievements in a Natural Experiment1

East Germany (EG) and West Germany (WG) had been divided by the inner-German frontier for more than 4 decades. In 1989, the frontier fell, and in 1990, East and West Germany were reunified. To study differences in attributional patterns as a consequence of this political change, the attributions of WG TV-sport commentators during the 1988 and 1992 Olympic Games were analyzed for their frequency and antecedents. Results show an increase in internal and stable attributions after success in contrast to failure attributions; the former to a greater extent in 1992. In 1988 and in 1992, the positive achievements of EG athletes were attributed more often to internal causes than were the positive achievements of WG athletes. In 1992, attributions for EG athletes were more likely to be stable than in 1988.     

Abstraction of prototypical information by adults and 10-month-old infants

The primary purpose of this study was to investigate whether preverbal infants, when presented with exemplars of an artificially constructed category, would abstract a prototypical representation of the category, and if so, whether this representation was formed by either "counting" or "averaging" the features that were varying among category members. Two experiments are reported. In Experiment 1, a set of stimuli was developed and tested for which it was demonstrated that adult subjects would readily abstruct either a modal or an average prototypical representation. The type of representation abstracted was found to be dependent on the discriminability of the feature values. In Experiment 2, 10-mo.-old infants were tested using a habituation paradigm with the stimuli developed in the first experiment. The results of this study indicated that the infants were also able to abstract the featural information that was varying among the exemplars of the category, and the infants formed an internal represenatation of the category by averaging feature values. Thus, the results clearly imply that infants are able to constructively process visual information and hence take a more active role in category formation than had been previously believed.     

Some results on random utility models

This paper extends earlier work on the properties of Thurstone choice models to the general random utility model (RUM), in which the components of the random utility vector are not necessarily independent and identically distributed, even apart from location shifts. The condition for two RUMs to be equivalent is established, and relationships between the choice axiom, decomposition, and other conditions are explored. In the special case of the Thurstone model, the conditions considered are all equivalent to the double exponential distribution.     

Within-person variability in response speed as an indicator of cognitive impairment in older adults

Within-person variability may be an important indicator of central nervous system compromise. In this study, within-person variability in response speed was examined in community-dwelling older adults, ages 64-92 years, using a new framework that takes into account both the extent (single versus multiple domains affected) and nature (amnestic versus non-amnestic) of the cognitive impairment. Those with multiple domains of impairment were more variable than those who showed an isolated area of impairment, regardless of whether memory was one of the domains affected. Further, for those with difficulties in two or more non-memory domains, increased variability was most evident in more cognitively demanding situations, when individuals had to manipulate information held briefly in mind, switch cognitive set or inhibit an automatic response. Finally, group differentiation was better achieved when within-person variability as opposed to mean speed of performance was considered.
