Aversive procedures: The minnesota experience

Aversive and deprivation procedures for controlling and reducing challenging behaviors have received increasing attention. Many states have adopted guidelines on the use of these procedures treating persons with developmental disabilities. The Minnesota state rule promulgated in October, 1987 requires reviews from both local and state-wide review committees on permitted, but controlled procedures. Data generated from state-wide committees revealed that (a) state operated regional treatment centers (RTCs) employed individual habilitative training programs with controlled procedures more frequently than community-based agencies (b) a higher proportion of RTC submissions were for treatment of self-injury than submissions from community services, and (c) RTCs had a higher usage of mechanical restraints than community facilities with both services settings using manual restraints more frequently than all other controlled procedures combined. Reasons for the above differences in the two service settings were discussed.     

Covariance structure analysis in several populations

This paper is concerned with the study of covariance structural models in several populations. Estimation theory of the parameters that are subject to general functional restraints is developed based on the generalized least squares approach. Asymptotic properties of the constrained estimator are studied; and asymptotic chi-square tests are presented to evaluate appropriate model comparisons. The method of multipliers and the standard reparametrization technique are discussed in obtaining the estimates. The methodology is demonstrated by a set of real data.Computer facilities were provided by the Computer Services Center, The Chinese University of Hong Kong. The authors are indebted to several anonymous reviewers for suggestions for improvement of this paper.     

Irrational beliefs as predictors of negative affective states

One effort to specify cognitive mediators related to dysfunctional emotional responses has been made by Ellis, who proposed that certain irrational beliefs elicit maladaptive emotional reactions. In order to test Ellis's hypotheses in a nonclinical sample, the Irrational Beliefs Test, two anxiety inventories, the MMPI-168, and a locus of control scale were completed by 32 male heavy social drinker undergraduates, who then kept daily records of their anxiety, anger, unhappiness, and drinking behaviors for 7 months. Four factors underlay the 10 beliefs but did not necessarily correlate with dysphoric affect. Certain irrational beliefs predicted daily unhappiness ratings over the 7-month period and daily anger ratings over 3 months, but the beliefs exhibited only a weak relationship with daily general anxiety ratings. Irrational beliefs, especially worrying about approval and competence, were strongly related to test anxiety and Spielberger's trait anxiety measure, were somewhat related to social anxiety and general anxiety, were minimally related to locus of control and social desirability, and were essentially unrelated to the MMPI-168's measures of depression and anxiety and to drinking behaviors. Although 2 of the irrational beliefs failed to exhibit relationships with negative affect, the other 8 show the predicted relationships to moods, providing support for a cognitive mediational model of maladaptive emotions in a nonpathological population.This research was partially supported by grants from the Alcoholism and Drug Abuse Institute, University of Washington, Seattle, from a National Institute of Mental Health small grant AA03947-01, and from a National Institute of Alcohol Abuse and Alcoholism postdoctoral training fellowship No. 1T32AA07171-01.

Influence of a televised model's vocalization pattern on infants

To assess the influence of a televised model's vocalizations on the vocal patterns of infant viewers, 32 infants at 6 months of age were presented either a televised adult model repeating a novel phoneme pattern (/ba/ba/ba/ba) or a control televised presentation of adult conversation selected from typical daytime programming. Sequential analyses of infant vocalizations revealed that infants exposed to the televised model altered their vocalization pattern, as indicated by a significant increase over base line levels in their production of a patterned series of discrete vocalizations. Infants exposed to the televised conversation showned no increase in this pattern of vocalization, and none of the infants in the study produced the novel phoneme (/ba/). The results indicate that televised presentation of discrete, repeated vocalizations can have an influence on the vocalization pattern of infants. The potential role of television in infant development is discussed.     

Behavior analysis of cigarette smoking

Patterns of cigarette smoking, treated as series of discrete events in time, were investigated with a variety of quantitative techniques designed to characterize individual subject smoking series and to illuminate the relationship between cigarette smoking and environmental events. Data were collected from a total of 35 subjects who were either participants in residential laboratory studies or in a smoking cessation program. Cigarette smoking events were found to be fairly irregularly distributed with respect to time within individual subject series. However, strong dependencies were found between the occurrence in time of individual acts of cigarette smoking and coffee drinking. In addition, the distribution and frequency of smoking events throughout one-hour activity sequences were found to be dependent upon the nature of the activity, and the temporal scheduling of activities was found to affect several quantitative indices of smoking patterns.     

MULTIVARIATE ASSESSMENT OF CONFLICT IN DISTRESSED AND NONDISTRESSED MOTHER-ADOLESCENT DYADS

A battery of measures was used to assess conflict between mothers and young adolescents (females and males, 11 to 15 years of age). Two groups of families, one composed of a distressed clinical sample (N = 38), the other a nondistressed normative sample (N = 40), participated. The assessment battery included retrospective judgments, frequency estimates, self-monitored home recording, and tape-recorded discussion of a home problem. Content of assessment measures tapped aspects of parental control, decisionmaking, self-reported interaction behavior, arguments, interaction behavior rated by independent “blind” observers, frequency and anger-intensity of specific problematic issues, and perceptions of positive and negative behaviors of the other family member. Based on univariate analyses, 21 of the 26 defined variables discriminated significantly in the predicted direction. Maternal and adolescent reports of behavior and independent ratings of tape-recorded interaction emerged as strong and consistent discriminators. Stepwise multivariate discriminant analysis provided successful classification of 100% of the families based on the inclusion of nine variables. In a cross-validation sample, 84% of the families were correctly classified. Implications for systematic outcome research as well as clinical application are discussed.     

The effects of attention-directing training on recognition memory task performance of three-year-old children

Thirty-eight 3-year-old children served as subjects in an investigation of recognition memory in which schematic faces differing only in the orientation of the eyes were employed as stimuli. A pretest was administered to all children, after which the two experimental groups received training in either attention to the distinctive feature of the training stimuli (also schematic faces) by means of a matching task, or in labeling the faces according to how they looked (sleepy, happy, sad, mad) and in using the labels to perform a matching task. After the training session all children were given a posttest on recognition memory of the faces. The verbally trained group obtained significantly higher scores on the posttest than either the feature or control groups. These results indicate that although the children were able to discriminate the faces, evidenced in their ease of performance on the training tasks, they were not able to use this knowledge unless given training in attaching labels to the stimuli, which enabled them to store the information for later use. Results are discussed in light of Gibson's (1969) theory of the developmental interrelations of cognitive processes.
