Functional analysis of aberrant behavior through measurement of separate response topographies

Functional analysis results for multiple topographies of aberrant behavior were graphed in an aggregate fashion and then separately for 48 clients. The results indicated that multiple topographies of behavior may be maintained by different contingencies. These results indicate that graphing functional analysis data in an aggregate fashion and then separately may improve the accuracy of their interpretation.     

The effects of directive and nondirective prompts on noncompliant vocal behavior exhibited by a child with autism

Results of an analogue functional analysis indicated that noncompliant vocal behavior exhibited by a young girl with autism was maintained by negative reinforcement. Follow-up analyses suggested that the immediate escape contingency assessed in the demand condition did not appear to maintain the behavior. Instead, noncompliant vocal behavior occurred in response to directive prompts. Nondirective prompts reduced noncompliant vocal behavior to near zero.     

Distortions of depth-order relations and parallelism in structure from motion

Four experiments related human perception of depth-order relations in structure-from-motion dis-plays to current Euclidean and affine theories of depth recovery from motion. Discrimination between parallel and nonparallel lines and relative-depth judgments was observed for orthographic projections of rigidly oscillating random-dot surfaces. We found that (1) depth-order relations were perceived veridically for surfaces with the same slant magnitudes, but were systematically biased for surfaces with different slant magnitudes. (2) Parallel (virtual) lines defined by probe dots on surfaces with different slant magnitudes were judged to be nonparallel. (3) Relative-depth judgments were internally inconsistent for probe dots on surfaces with different slant magnitudes. It is argued that both veridical performance and systematic misperceptions may be accounted for by a heuristic analysis of the first-order optic flow.     

TOWARD A FUNCTIONAL ANALYSIS OF SELF-INJURY

This study describes the use of an operant methodology to assess functional relationships between self-injury and specific environmental events. The self-injurious behaviors of nine developmentally disabled subjects were observed during periods of brief, repeated exposure to a series of analogue conditions. Each condition differed along one or more of the following dimensions: (1) play materials (present vs absent), (2) experimenter demands (high vs low), and (3) social attention (absent vs noncontingent vs contingent). Results showed a great deal of both between and within-subject variability. However, in six of the nine subjects, higher levels of self-injury were consistently associated with a specific stimulus condition, suggesting that within-subject variability was a function of distinct features of the social and/or physical environment. These data are discussed in light of previously suggested hypotheses for the motivation of self-injury, with particular emphasis on their implications for the selection of suitable treatments.     

School adjustment of children with observable disabilities

This study investigated school behavior and achievement of children with mild degrees of observable physical disability. Children from two different disability types (cleft palate and cerebral palsy) were compared with each other and to a control group in order to determine potential similarities across disability types. Children (N=78) from each of the two disability groups were individually matched to each other and to a normal control group (N=39) by sex, IQ, socioeconomic status, age, and grade. They were compared on the basis of teachers' behavioral ratings and achievement test scores. All children attended regular public school classrooms. The two disability groups displayed significantly greater inhibition of impulse and lower educational achievement than did the controls. The implication of similar school adjustment across mild but observable subtypes is discussed.Parts of this article were presented at the meeting of the American Psychological Association, Washington, D.C., September 1976. The study was supported in part by PHS Grant DE-00853, the National Institute of Dental Research.     

Hyperlexia as a variant of developmental language disorder

Memory and associative reasoning skills of 10 hyperlexic children are examined. The results suggest superior visual and isolated auditory memory skills along with impaired associative language ability. The results are discussed in relation to various theories of hyperlexia.     

Cognitive career counseling: A rationalemotive approach to career development

The application of cognitive techniques to the career counseling process has been minimal. Since the career and personal development of individuals is interwoven, practitioners from a variety of disciplines are faced with a wide range of complex presenting problems regardless of their specialty. Providing occupational information and assessing job skills are partial components of the career counseling process. This paper addresses the cognitive barriers which interfere with successful career development. Cognitive career counseling (CCC) is described as a methodology for helping clients modify their vocational irrational beliefs (VIBes) so that they may achieve their career and personal goals during realistically unstable changes in economic conditions.Diana R.
