The effects of differential negative reinforcement of other behavior and noncontingent escape on compliance

The present study evaluated the effects of noncontingent escape and differential negative reinforcement of other behavior in reducing problem behaviors and increasing compliance in 2 children with disabilities. Results showed that both methods reduced problem behavior and increased compliance for both children.     

The effects of presession attention on problem behavior maintained by different reinforcers

The effect of presession attention on the later occurrence of problem behavior was examined with elementary-school children with a range of disabilities. Results of analogue functional analyses suggested an escape function, an attention function, or both. Following the analogue functional analyses, the effects of two antecedent conditions (10-min ignore vs. 10-min attention) were compared on problem behavior in subsequent test conditions. For participants who displayed attention-maintained problem behavior, the test condition involved contingent attention for problem behavior. For participants who displayed escape-maintained problem behavior, the test condition involved contingent escape for problem behavior. Results indicated that participants who displayed attention-maintained problem behavior displayed less problem behavior following presession exposure to attention than when ignored. No such effect was found for presession attention on escape-maintained problem behavior. We discuss matching antecedent-based interventions to the results of functional analysis.     

Analysis of precurrent skills in solving mathematics story problems

We conducted an analysis of precurrent skills (responses that increase the effectiveness of a subsequent or "current" behavior in obtaining a reinforcer) to facilitate the solution of arithmetic word (story) problems. Two students with developmental disabilities were taught four precurrent responses (identifying the initial value, change value, operation, and resulting value) in a sequential manner. Results of a multiple baseline design across behaviors showed that the teaching procedures were effective in increasing correct performance of each of the precurrent behaviors with untaught problems during probes and that once the precurrent behaviors were established, the number of correct problem solutions increased.     

Equivalence relations in individuals with language limitations and mental retardation

The study of equivalence relations exhibited by individuals with mental retardation and language limitations holds the promise of providing information of both theoretical and practical significance. We reviewed the equivalence literature with this population, defined in terms of subjects having moderate, severe, or profound mental retardation. The literature includes 55 such individuals, most of whom showed positive outcomes on equivalence tests. The results to date suggest that naming skills are not necessary for positive equivalence test outcomes. Thus far, however, relatively few subjects with minimal language have been studied. Moreover, we suggest that the scientific contributions of studies in this area would be enhanced with better documentation of language skills and other subject characteristics. With recent advances in laboratory procedures for establishing the baseline performances necessary for equivalence tests, this research area is poised for rapid growth.     

Unemployment, Underemployment, and Mental Health: Conceptualizing Employment Status as a Continuum

The economy is one of the most important social environments that affect well-being, and community psychologists have long studied the social costs of one key economic stressor—job loss. But economically inadequate employment has received much less research attention than unemployment in regard to mental health effects. This paper contrasts these two literatures and considers factors that might account for their differential growth including actual rates of unemployment and underemployment. Recent panel studies offer no support for another possible basis for this differential growth—the assumption that inadequate employment is more like adequate employment than unemployment. Implications of a paradigm shift from a dichotomous perspective (employment vs. unemployment) to a continuum perspective with variations of both unemployment and employment are discussed for research and prevention. Another implication is the need to expand standard labor force statistics to reflect better the degree of underemployment.     

Hostile attributional tendencies in maltreated children

The hostile attributional tendencies of maltreated children in elementary school across key relationship figures (i.e., parents, teachers, and peers), the relation between children's hostile attributional tendencies and the frequency and severity of maltreatment, and the role of children's hostile attributions of their parents in mediating the relation between maltreatment and children's hostile attributions of unfamiliar peers were examined. The sample consisted of 44 maltreated and 56 nonmaltreated children (females = 51) of mixed ethnicity. Subjects were administered a 20-item measure of attributional processes. The results indicated that relative to nonmaltreated children, physically abused boys were more likely to attribute hostile intentions to a variety of relationship figures, including their parents, an unfamiliar teacher, their best friend, and unfamiliar peers. A positive relation was also found between the frequency of physical abuse and hostile attributional tendencies among males. Finally, support was found for the role of children's hostile attributions of their mothers in mediating the relation between physical abuse and children's hostile attributions of unfamiliar peers. The results support a link between physical abuse and hostile attributional tendencies in children in early elementary school.     

The Role of Creativity in Marriage and Family Therapy Practice: A National Online Study

The purpose of this study, using an online methodology, was to investigate therapists' perceptions of the role of creativity in couples' and family therapy. Along with completing a quantitative measure assessing creativity in their work, participants responded to four open-ended questions which addressed the meaning of creativity, characteristics of a creative family therapist, some creative interventions they have used with couples and families, and barriers to their own creativity as a family therapist. A total of 142 marriage and family therapists in 36 states in the United States participated. The findings shed light on the unique importance of creativity in couples and family treatment.     

心算加工年老化及其机制研究

以１７２名２０－７９岁成人为被式对心算加工的年老化过程及其机制进行了研究。任务为连续减法心算,依难度分为５种：１０００－１,１０００－３,１０００－１３及１０００－１７。结果表明,年龄与心算难度存在明显的交互作用,且随着年龄增加,不同难度心算效率均以幂函数形式降低。     

心算活动机制的研究

心算是一种重要的思维活动,是认知心理学的研究主题之一。心算活动具有明显的问题大小效应,其加工过程与工作记忆和长时记忆存在密切关系。此外,对心算的加工机制进行跨学科（认知心理学、神经科学等）的综合研究,是今后心算研究的主要方向。     

心算加工年老化及其机制研究

以172名20－79岁成人为被试对心算加工的年老化过程及其机制进行了研究。任务为连续减法心算,依难度分为5种：1000－1、1000－3、1000－7、1000－13及1000－17。结果表明,年龄与心算难度存在明显的交互作用,且随着年龄增加,不同难度心算效率均以幂函数形式降低。结构方程建模分析发现心算加工年老化过程存在两个中介作用因子,即速度因子和非速度因子,且速度因子对非速度因子存在明显的正效应。
