Sensory extinction of stereotyped object-dropping: Identification of a reinforcer for skill training

Stereotyped motor behavior, resistant to treatment by nonaversive means, can be effectively reduced by sensory extinction. Sensory extinction is a procedure which can identify the powerful sensory reinforcers maintaining stereotyped behavior. In this single-subject, multiple-baseline experiment, the elimination of auditory feedback to a workshop trainee who was blind and profoundly retarded, extinguished stereotyped object-dropping. Contingent auditory stimulation delivered for a fixed ratio of correct object placements increased correct responding. Results were discussed in terms of the utility of selecting reinforcers on the basis of empirical manipulations, such as sensory extinction, and in terms of self-control versus contingency functions of sensory reinforcement.     

Implementing a long-term computerized remedial reading program with synthetic speech feedback: Hardware,software, and real-world issues

This paper discusses hardware choices, software developments, implementation issues, and preliminary results from an ongoing long-term remedial reading study. Reading-disabled children read books on microcomputers linked to speech synthesizers, obtaining speech feedback on difficult words at whole-word, syllable, or subsyllable levels of segmentation. Word-recognition ability and attitude about reading improved for children using the system. In addition, segmented feedback especially benefited phonological word-decoding skills for most of the children.     

Sex differences in endorsement of influence tactics and political behavior tendencies

Sex differences in the endorsement of influence tactics and political behavior tendencies were surveyed among 337 employees (176 males and 161 females). The sample was composed of managers, business owners, and professional, technical, sales, and office support workers from a variety of organizations. No significant differences were found between males and females with respect to scores on the Political Orientation Questionnaire, preference for teamwork, exchange of favors, and upward appeal. However, women were significantly less likely than men to perceive themselves as relying on charm, manipulative tactics, and personal appearance to achieve results and gain advantage. None of the sex differences could be attributed to years of job experience.     

The distressed family and wounded children

This article addresses the issue of the need for clergy to be better informed regarding the assessment of child abuse and neglect. It provides a quick reference guide to assist clergy in assessing the risk factors in the abusive family with guidelines for the recognition of child maltreatment. In a society that is marked by unprecedented levels of child maltreatment reporting and an ever increasing shortage of mental health services, clergy are increasingly being confronted by situations involving potential child maltreatment that require expert crisis intervention skills. This article provides specific, concrete guidelines for clergy confronted with situations that call for the recognition of child maltreatment.Andrew J.

Selective responsiveness of chronically ill children to assessments of depression.

Many investigators have noted that depression is a common symptom among pediatric cancer patients. However, prevalence rates vary widely across studies. This variation in prevalence rates may be due, in part, to selective reporting of patients based on measures used and environmental cues. In this study, we evaluated 50 chronically ill pediatric patients (19 cancer and 31 diabetic patients) for their use of selective reporting of depression. Factors in the 2 x 2 design were Intervention (disclosure videotape and cartoon videotape) and Examiner (familiar examiner and unfamiliar examiner). In the Intervention manipulation, subjects were shown either a videotape prompting the child that self-disclosure was appropriate or a tape of a cartoon (control condition). In the Examiner manipulation, subjects were administered the experimental measures by either a familiar (parent) or unfamiliar (research assistant) examiner. Dependent variables were the Children's Depression Inventory (CDI; Kovacs, 1981), the Depression scale of the Roberts Apperception Test for Children (RATC; McArthur & Roberts, 1982), and a depression measure taken from the Child Behavior Checklist (CBCL; Achenbach & Edelbrock, 1983). As hypothesized, the Examiner x Intervention interaction revealed that children who did not view the disclosure videotape and who were tested by an unfamiliar examiner gave significantly lower self-reports of depression on the CDI than children in the other conditions. However, parent and child projective reports of depression did not vary as a function of experimental condition. The results are interpreted as selective responding on the part of pediatric patients. Limitations of assessing internal psychological states in children are discussed.     

Development of conduct problems and peer rejection in preschool children: A social systems analysis

The development of impulsive-aggressive problem behavior and peer rejection was examined in sixty 4- to 5-year-old boys from low-income family backgrounds. Children's sociometric status and behavioral adjustment were assessed longitudinally at the beginning and end of the preschool year, and related to measures of peer interaction at three different points in time. Boys identified as socially rejected and aggressive in the beginning of the year were highly likely to be identified as such at the end of the year. Early in the preschool year, these children contributed to their own rejection by initiating socially aversive exchanges with peers. Although peers clearly perceived these problems, they did not reciprocate with counteraggression at first. However, as time passed, peers began to actively victimize these children, and most of the aggression on the part of victims became reactive in nature. Thus, the current findings strongly support a transactional model of the development of early peer rejection and conduct problems.The author is indebted to the Head Start teachers, children, and parents who participated, and to the following individuals for their invaluable help with data collection and coding: Margo Bonner, Beth O'Connell, Cindy Friedman, Elizabeth Jamner, Karen Lifgren, Marina Post, Jacqueline Raznick, Lisa Walsh, and Karen Weitzner.     

Counselling after Stroke: An Unmet Need?

Information was gathered by means of a questionnaire survey and interviews from a group of patients (N = 17) and health professionals (N=13) working within a stroke unit, concerning the emotional needs of patients and and their relatives and how staff responded to these needs. Although most of the staff had received some training or information about counselling and felt that their interactions with patients often involved an element of counselling, there was strong support for separate specialised counselling services to deal with psychological problems suffered by both patients and their relatives. Patients rated assistance with personal and emotional worries and advice about physical problems as equally useful. A strong need for a counselling service in some form or other was expressed by patients. Neither the level of the patients' social support nor the presence or absence of aphasia, however, predicted the strength of interest expressed. It is concluded that specialised psychological help could be useful in various ways for both in- and out-patients and for their families.
