Renewal after overexpectation

Four magazine approach experiments were performed with rats to explore the decrement produced by reinforcing a compound of two previously conditioned stimuli. Compound presentation produced the usual over-expectation decrement in responding to the individual stimuli. However, testing in an alternative, but similarly treated, context allowed renewal of the initial responding to the individual stimuli. This renewal is similar to that seen after a decrement produced by nonreinforcement. It joins other results in suggesting that the decrement produced in extinction and overexpectation may be due to the same mechanism.     

Parental coping with children's negative emotions: relations with children's emotional and social responding

This study examined the relation between parents' reactions to children's negative emotions and social competence. Additionally, the role of parental emotional distress in children's emotional socialization was examined. The emotional reactions of 57 preschoolers (33 girls, 24 boys; M age = 59.2 months) were observed during their free-play interactions. Parents (mostly mothers) completed questionnaires about their reactions to children's negative emotions. An index of children's social competence was obtained from teachers. Results indicated that the relation between harsh parental coping strategies and children's emotional responding was moderated by parental distress. In addition, the relation of the interaction of parental coping and distress to children's social competence was mediated by children's level of emotional intensity. It was concluded that distressed parents who use harsh coping strategies in response to children's negative emotions have children who express emotion in relatively intense ways. In turn, these children find it relatively difficult to behave in a socially competent manner.     

Evaluating conditioning of related and unrelated stimuli using a compound test

Three experiments used a compound test procedure to evaluate whether superior conditioning results from the pairing of stimuli that are related to each other. In each case, a stimulus compound was tested after its component conditioned stimuli (CSs) had been conditioned by the same unconditioned stimuli (USs) arranged such that either related or unrelated CSs and USs were paired. Experiment 1 explored auditory and gustatory stimuli conditioned by LiCl or shock, using rats. Experiments 2 and 3 used second-order conditioning in pigeons to pair stimuli that were similar by virtue either of qualitative features or of shared physical location. In each case, the compound test provided clear evidence that pairing related stimuli produces superior associative learning.     

Children's reports of emotional,physical and sexual maltreatment by educational staff in Israel

OBJECTIVES: This paper reports on the first nationally representative study on the prevalence of emotional, physical, and sexual victimization of children by school staff in Israel. The study identifies groups of children that are at higher risk for such maltreatment. We examine the differences in staff-induced victimization by the children's gender, age group (junior high vs. high school), cultural groups (Jewish non-religious, Jewish-religious and Arab schools) and by socioeconomic status of the children's families. METHOD: The study is based on a nationally representative sample of 10,410 Israeli students in Grades 7-11 in 161 schools across Israel. Students completed questionnaires during class. In addition, we obtained data on the socioeconomic status of the families of the students in each school. RESULTS: Overall, children reported high rates of victimization by staff members. Almost a quarter of all children participating in this study reported being emotionally maltreated by a staff member, almost a fifth (18.7%) reported being a victim of at least one type of physical forms of maltreatment, and 8.2% reported on at least one sexually inappropriate behavior by a staff member. The most vulnerable groups for all types of maltreatment were males, children in junior high schools, children in Arab schools, and children in schools with a high concentration of students coming from low-income and low-education families. CONCLUSIONS: The overall prevalence rates of staff maltreatment should be considered high and unacceptable. Although rates of physical and sexual maltreatment were lower than emotional maltreatment, they were still high and are worthy of greater attention. Both cultural beliefs and low family socioeconomic status increase vulnerability to staff maltreatment. We suggest conducting an educational campaign to reduce rates of staff maltreatment. We also recommend allocating more resources to support staff in low SES neighborhoods, to alleviate their stress and to provide them with the support that would reduce maltreatment of children in the educational system.     

Raising the bar: the importance of hospital library standards in the continuing medical education accreditation process

The Connecticut State Medical Society (CSMS) reviews and accredits the continuing medical education (CME) programs offered by Connecticut's hospitals. As part of the survey process, the CSMS assesses the quality of the hospitals' libraries. In 1987, the CSMS adopted the Medical Library Association's (MLA's) "Minimum Standards for Health Sciences Libraries in Hospitals." In 1990, professional librarians were added to the survey team and, later, to the CSMS CME Committee. Librarians participating in this effort are recruited from the membership of the Connecticut Association of Health Sciences Librarians (CAHSL). The positive results of having a qualified librarian on the survey team and the invaluable impact of adherence to the MLA standards are outlined. As a direct result of this process, hospitals throughout the state have added staffing, increased space, and added funding for resources during an era of cutbacks. Some hospital libraries have been able to maintain a healthy status quo, while others have had proposed cuts reconsidered by administrators for fear of losing valuable CME accreditation status. Creating a relationship with an accrediting agency is one method by which hospital librarians elsewhere may strengthen their efforts to ensure adequate library resources in an era of downsizing. In addition, this collaboration has provided a new and important role for librarians to play on an accreditation team.
