Multiaxial empirically based assessment: Parent,teacher, observational,cognitive, and personality correlates of Child Behavior profile types for 6- to 11-year-old boys

The purpose of this study was to determine whether profile patterns derived from parents' ratings of clinically referred boys were significantly associated with differences in functioning identified via teachers' ratings, direct observations, cognitive tests, and personality measures. Subjects were 185 6- to 11-year-old boys who were referred to an outpatient psychiatric service or school psychologist and whose Child Behavior Checklist (CBCL) profiles correlated significantly with types previously identified through cluster analysis. Comparisons of boys classified by six CBCL profile types and Internalizing versus Externalizing groupings of these types showed many differences that are not apt to be evident in linear correlations between the different sources of data. The findings provide a basis for research on differences between profile patterns with respect to etiology, course, prognosis, and responsiveness to interventions. They also indicate the potential importance of higher-order patterns of functioning that extend across multiple sources of data.This research was supported by grants from the Spencer Foundation, the W.

Constraints on spontaneous transfer in problem-solving tasks

In three experiments, we investigated the conditions under which relevant knowledge is spontaneously transferred to problem-solving tasks. Subjects were presented with key concepts that could help them solve problems presented at a later time in the experiment. The key concepts were embedded in statements that had surface structures similar or dissimilar to those of the problems and that emphasized relevant or irrelevant properties of the key concepts for the problemsolving task (contextual relevance). The results indicated that the spontaneous transfer of clue information to subsequent problem-solving tasks is affected by the contextual relevance and the surface-structure similarity of the clue statements to the problems. The findings also suggested that the surface-structure similarity and the contextual relevance of clue statements differentially affect the accessibility and appropriate application of key concepts in problem-solving tasks. The implications of these results for understanding the transfer of knowledge in problem-solving tasks are discussed.     

TREATMENT OF PICA THROUGH MULTIPLE ANALYSES OF ITS REINFORCING FUNCTIONS

We conducted functional analyses of the pica of 3 participants. The pica of 1 participant appeared to be maintained by automatic reinforcement; that of the other 2 participants appeared to be multiply controlled by social and automatic reinforcement. Subsequent preference and treatment analyses were used to identify stimuli that would compete with the automatic function of pica for the 3 participants. These analyses also identified the specific aspect of oral stimulation that served as automatic reinforcement for 2 of the participants. In addition, functional analysis-based treatments were used to address the socially motivated components of 2 of the participants' pica. Results are discussed in terms of (a) the importance of using the results of functional analyses to develop treatments for pica and (b) the advantages of developing indirect analyses to identify specific sources of reinforcement for automatically reinforced behavior.     

ON THE REINFORCING EFFECTS OF THE CONTENT OF VERBAL ATTENTION

During a functional analysis, a boy with autism and oppositional defiant disorder displayed destructive behavior that was maintained by attention in the form of verbal reprimands (e.g., “Don't hit me”). In a second analysis, contingent verbal reprimands produced higher rates of the behavior than contingent statements that were unrelated to the target response (e.g., “It is sunny today”), suggesting that some forms of attention were more reinforcing than others. A treatment based on these analyses reduced the behavior to near-zero levels.     

DIFFERENTIAL REINFORCEMENT OF ALTERNATIVE BEHAVIOR AND DEMAND FADING IN THE TREATMENT OF ESCAPE-MAINTAINED DESTRUCTIVE BEHAVIOR

The escape-maintained destructive behavior of a boy with autism was reduced during instructional sequences with differential reinforcement of compliance (DRA), escape extinction without physical guidance, and demand fading. The procedure decreased destructive behaviors to near-zero levels and greatly increased compliance.     

EFFECTS OF EQUAL AND UNEQUAL REINFORCER DURATION DURING FUNCTIONAL ANALYSIS

In the functional analysis described by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994), reinforcer duration varied across conditions (e.g., brief attention vs. 30 s of escape); this may result in unequal exposure to the establishing operations for aberrant behavior. In this study, we compared the effects of unequal and equal reinforcer duration during a functional analysis. The results showed that reinforcer duration affects the rate of aberrant behavior and may potentially alter functional analysis interpretation.     

A WATER-PROMPTING PROCEDURE FOR THE TREATMENT OF URINARY INCONTINENCE

Based on clinical observations of a naturally occurring phenomenon, a water-prompting procedure was used to facilitate toilet training with a 9-year-old boy with profound mental retardation. Other frequently used toilet-training procedures were either ineffective or were associated with increased self-injury. The water-prompting treatment package may increase continence by eliciting and reinforcing urination under specific stimulus conditions.     

A COMPARISON OF SENSORY INTEGRATIVE AND BEHAVIORAL THERAPIES AS TREATMENT FOR PEDIATRIC FEEDING DISORDERS

We compared the effects of escape extinction (EE) plus noncontingent reinforcement (NCR) with sensory integration therapy as treatment for the feeding problems of 2 children. Results indicated that EE plus NCR was more effective in increasing acceptance, decreasing inappropriate behavior, and increasing amount consumed relative to sensory integration for both children. The results are discussed in terms of the challenges of evaluating sensory‐integration‐based treatments, and the reasons why component analyses of multicomponent treatments like sensory integration are important.     

Spatio-temporal priority revisited: the role of feature identity and similarity for object correspondence in apparent motion

We live in a dynamic environment in which objects change location over time. To maintain stable object representations the visual system must determine how newly sampled information relates to existing object representations, the correspondence problem. Spatiotemporal information is clearly an important factor that the visual system takes into account when solving the correspondence problem, but is feature information irrelevant as some theories suggest? The Ternus display provides a context in which to investigate solutions to the correspondence problem. Two sets of three horizontally aligned disks, shifted by one position, were presented in alternation. Depending on how correspondence is resolved, these displays are perceived either as one disk "jumping" from one end of the row to the other (element motion) or as a set of three disks shifting back and forth together (group motion). We manipulated a feature (e.g., color) of the disks such that, if features were taken into account by the correspondence process, it would bias the resolution of correspondence toward one version or the other. Features determined correspondence, whether they were luminance-defined or not. Moreover, correspondence could be established on the basis of similarity, when features were not identical between alternations. Finally, the stronger the feature information supported a certain correspondence solution the more it dominated spatiotemporal information.
