EFFECTIVENESS OF FUNCTIONAL COMMUNICATION TRAINING WITH AND WITHOUT EXTINCTION AND PUNISHMENT: A SUMMARY OF 21 INPATIENT CASES

Functional communication training (FCT) is a frequently used treatment for reducing problem behavior exhibited by individuals with developmental disabilities. Once the operant function of problem behavior is identified by a functional analysis, the client is taught to emit an appropriate communicative response to obtain the reinforcer that is responsible for behavioral maintenance. Studies on FCT have typically used small numbers of participants, have reported primarily on clients for whom FCT was successful, and have varied with respect to their use of other treatment components. The main purposes of the present study were to evaluate the efficacy of FCT for treating severe problem behavior in a relatively large sample of individuals with mental retardation (N = 21) and to determine the contribution of extinction and punishment components to FCT treatment packages. FCT with extinction was effective in reducing problem behavior for the majority of clients and resulted in at least a 90% reduction in problem behavior in nearly half the applications. However, when demand or delay-to-reinforcement fading was added to FCT with extinction, treatment efficacy was reduced in about one half of the applications. FCT with punishment (both with and without fading) resulted in at least a 90% reduction in problem behavior for every case in which it was applied.     

Pathological narcissism and serial homicide: Review and case study

Serial homicide, as a psychopathological condition, has been described as long ago as 1886. The traits and characteristics of serial murderers are varied, as are the theories that attempt to explain their motivation. Theorists have emphasized, for example, traumatic events in early life, sexual disturbance and dynamics, and neurobiological abnormalities. In the past fifteen years, as narcissistic disturbance in general has been better understood, a relationship has been noted between pathological narcissism and serial homicide. Narcissistic personality disorder, narcissistic injury, underlying feel-ings of inadequacy and humiliation, self-glorifying compensatory fantasies, and the erection of narcissistic defenses have all been mentioned as important factors in un-derstanding the serial killer. An illustrative case report, which encompasses many of these characteristics, is presented here along with a review of clinical research, theory, and findings.     

Understanding and Treating Pain in Ethnically Diverse Patients

A revolution has taken place during the past 25 years in the understanding and treatment of chronic pain. Psychologists have contributed tremendously to this revolution. However, the primary psychological models of pain treatment have failed to adequately integrate the empirical findings and theoretical understanding of the role of ethnic factors. The goal of this paper is to address this problem by demonstrating the importance of understanding ethnic factors in treating pain, providing an overview of ethnic factors in pain, and proposing guidelines for Clinical Psychologists who treat pain patients from ethnically diverse backgrounds.     

Obedience as a function of experimenter competence

The purpose of this study was to investigate obedience to an E’s commands as a function of E competency. Based upon Orne’s (1962, 1969) discussion of the demand characteristics inherent in the typical aggression study, it was hypothesized that E incompetence would decrease S obedience. Competence was manipulated by: (1) presenting some Ss with a nervous and inexperienced E, and (2)“accidentally” killing the victim (a rat) midway through the experiment. Thirty-two undergraduate female Ss participated in the experiment—supposedly a study on the physiological effects of stress. Obedi6nce was operationalized as the difference, in simple reaction time, between trials on which Ss were told that their response might result in shock to the rat and trials on which they were told that their response might save the rat from shock. Significant differences in obedience were obtained between competent and incompetent E conditions, and a significant “kill” effect was found in the competent E conditidn. The results of this study suggested that the extreme acts of obedience observed in the laboratory (e.g., Milgram, 1963) occur only when E is perceived as competent. This finding imposes limits on the generalizability of laboratory studies of obedience.     

Behavioral Indicators of Interpersonal Attraction1

The laboratory study of attraction is based almost exclusively on verbal measures of the dependent variable. Various findings suggest that the physical distance separating two individuals indicates the degree of attraction between them. In two experiments, attitude similarity between a subject and two stooges was manipulated. Females were more attracted to and sat more closely beside a similar than a dissimilar stranger (p < .01); males were more attracted to and sat directly across from a similar rather than a dissimilar stranger (p < .02).     

A necessary and sufficient formula for matric factoring

For the purpose of extracting factors from matrices, it is proved that a certain formula is both necessary and sufficient. In factor analysis, the formula may be applied either to the correlation matrix, or directly to the score matrix (assuming the communality problem is solved). As many factors as desired can be extracted in one operation. Having such a compact formulation is useful for teaching as well as computing purposes, since it includes all techniques of factor extraction as special cases.On leave from the Israel Institute for Applied Social Research.
