Cultural diversity and treatment of children.

The increasing cultural diversity of child clients has produced a cascade of new issues and concerns for psychological practice, theory, and research. Available evidence and pertinent theory are reviewed on such topics as the predictive utility and treatment consequences of ethnic membership, whether treatments should be generic or specific to cultural groups, the degree of privilege that should be accorded to same-culture therapists, and the relative desirability of different modalities of treatment for children of different cultural groups. The concept of cultural compatibility of treatment is explored and evaluated. A broad agenda of hypotheses for research and development is suggested, and some guidelines for clinical practice and policy are proposed. It is concluded that insofar as possible, treatment for all children should be contextualized in their family's and community's structure of meanings, relationships, and language.

The logical status of metacognitive training.

It is argued that knowing-how (to perform) is not dependent on knowing-that (knowing propositions about performance). Existing evidence allows any benefits from "metacognitive" training to be attributed to generalization training, not to the announcement of rules. Rules may encourage the subject to learn new tasks, but these tasks must be learned in the contexts of eventual application.

A verbal behavior analysis of auditory hallucinations.

A review of recent research on the non-medical control of auditory hallucinations is presented. It is suggested that the decreases in hallucinatory behavior obtained in studies using aversive contingencies may be attributable to the disruption of the chains of behavior involved. The results of several additional studies are interpreted as indicating that methods of stimulus control and the use of incompatible behaviors may be effective in reducing the rate of auditory hallucinations. Research relating auditory hallucinations to subvocalizations is presented in support of the view that hallucinatory phenomena are sometimes related to the subject's own vocal productions. Skinner's views (1934, 1936, 1953, 1957, 1980) are then presented as possible explanations of some hallucinatory behavior. It is suggested that some auditory hallucinations consit of the mishearing of environmental and physiological stimuli as voices in a fashion similar to that which Skinner observed in his work with the verbal summator. The maintenance of long chains of such responses may be largely attributable to self-intraverbal influences (such as are present during automatic writing). With some auditory hallucinations, this progression involves first mishearing ambiguous stimuli as voices and then attributing the voices to some cause (e.g., insanity, the television, radio, or God). Later, the frequent and ongoing chains of such behavior may contaminate other verbal responses. Such verbal behavior may be parasitic on "normal verbal behavior" (and hence, not directly dependent on consquences for maintenance), may be cued by various stimuli (including respiration), and may interfere with other covert and overt behavior. Several studies to investigate this view are presented. It is hoped that such research will lead to a better understanding of the major issues involved in the etiology and treatment of auditory hallucinations in particular and perhaps of psychosis in general.

Observation procedure, observer gender, and behavior valence as determinants of sampling error in a behavior assessment analogue.

Several factors thought to influence the representativeness of behavioral assessment data were examined in an analogue study using a multifactorial design. Systematic and unsystematic methods of observing group behavior were investigated using 18 male and 18 female observers. Additionally, valence properties of the observed behaviors were inspected. Observers' assessments of a videotape were compared to a criterion code that defined the population of behaviors. Results indicated that systematic observation procedures were more accurate than unsystematic procedures, though this factor interacted with gender of observer and valence of behavior. Additionally, males tended to sample more representatively than females. A third finding indicated that the negatively valenced behavior was overestimated, whereas the neutral and positively valenced behaviors were accurately assessed.
