A COMPARISON OF DIFFERENTIAL REINFORCEMENT AND NONCONTINGENT REINFORCEMENT TO TREAT FOOD SELECTIVITY IN A CHILD WITH AUTISM

We compared differential reinforcement plus escape extinction to noncontingent reinforcement plus escape extinction to treat food selectivity exhibited by a young child with autism. The interventions were equally effective for increasing bite acceptance and decreasing problem behaviors. However, a social validity measure suggested that noncontingent reinforcement was preferred by the child's caregiver.     

Disclosure of Genetic Research Results to Members of a Founder Population

There is currently extensive discussion and debate in the literature on how, when, and to whom genetic research results should be returned (see Genetics in Medicine, April 2012 issue). Here, we describe our experience in disclosing genetic information on Mendelian disorders discovered during the course of our research in the Hutterites. We first assessed attitudes toward the disclosure of carrier results, which revealed that many individuals wanted carrier information and that many intended to use the information in family planning. Based on this information, we developed a pilot study to test and disclose cystic fibrosis (CF) carrier status. Next, a larger scale project was developed in order to disclose genetic research results for 14 diseases to those interested in receiving the information. We developed brochures, offered a live interactive educational program, conducted a consent process, and disclosed results in letters mailed to the consented individuals. Overall, ~80 % of individuals who participated in the educational program signed consent forms for the release of their results for 14 diseases. We describe our experience with returning individual genetic research results to participants in a population-based research study.     

Anxiety across the transition to parenthood: change trajectories among low-risk parents

Background and Objectives: A number of sources suggest changes in anxiety across the transition to parenthood may be experienced by parents in different ways, yet no studies have examined whether new parents experience changes in anxiety in distinct subgroups. Design: We conducted a longitudinal study of 208 first-time parents (104 couples) from a low-risk population. Parents were interviewed from the third trimester of pregnancy to nine-months postpartum. Methods: The current study utilized latent class growth analysis to explore subgroups of change in symptoms of anxiety. Based on stress and coping theory, we also examined a number of personal and social prenatal predictors of subgroup membership. Results: We identified two distinct change trajectories: (1) moderate and stable and (2) low and declining. We also found prenatal depression, expected parenting efficacy, and relationship satisfaction were significantly associated with subgroup membership. Conclusions: Our results suggest a majority of new parents adjust well to parenthood in terms of anxiety, while a smaller subgroup of parents experience continually higher levels of anxiety months after the baby is born.     

Self and peer nominations of bullying: An analysis of incident rates,individual differences,and perceptions of the working environment

Within workplace bullying research, the use of different criteria to identify victim samples, and a tendency to rely on self-reported victimization without including reports from other stakeholders have been considered major methodological problems associated with incidence studies (Cowie, Naylor, Rivers, Smith, & Pereira, 2002; Hoel, Rayner, & Cooper, 1999; Randall, 2001). Using diverse criteria to identify victim and perpetrator samples (such as self report, peer report, and self- and peer report), this study found rates of victimization and bullying varied quite considerably. Rates for victims ranged from 3.9% to 39.6% and for perpetrators from 2.7% to 19.3%. Differences in personality and perceptions of the organizational environment were then examined between victim/bully groups and a control sample. Results indicated that all victim samples differed significantly from controls on stability. However, self- and peer-reported victims differed significantly from controls on both the poised and relaxed subscales, whereas self-reported victims only differed significantly on the relaxed subscale. Additionally, self- and peer-reported victims were the only group that significantly differed from controls in their views of the negative aspects of the work environment. The notion that victim and perpetrator samples are not homogenous groups and considerations of why this is the case are discussed.     

Development of Family Therapy in Hong Kong

This paper provides an insight into the development and growth of family therapy in Hong Kong. Family therapy was introduced in Hong Kong in the early 1980s and is now gaining ground. The authors give a historical account of the development of family therapy in Hong Kong, and report on its progress and achievement for the past three decades there. The field has gone through several stages of development. The 1980s were marked by an importation of Western family therapy models, during which overseas expertise was tapped to promote family therapy. The 1990s were characterized by a blossoming of different schools of family therapy on the local scene. Most schools established their own practice centers, and training packages were tailor-made for local use. The 2000s were an important era of family therapy development in Hong Kong. The field has nurtured a new generation of leaders (both academics and front-line practitioners and trainers) who play an essential role in advancing its development. The paper concludes by identifying problems in clinical practice, professional training, and research and knowledge development, and proposes ways of overcoming these difficulties.     

公费教育政策满意度对师范生教师职业认同的影响—社会认知因素的影响

采用问卷法,以839名公费师范生为研究对象,探究公费师范生政策满意度对师范生教师职业认同的影响,考察公费教育政策满意度、职业决策自我效能感、职业结果预期以及教师职业认同的关系。结果发现：（1）公费教育政策满意度显著正向预测教师职业认同;（2）职业决策自我效能感和职业结果预期在政策满意度和教师职业认同的关系中起中介作用,完全中介支持性政策满意度与教师职业认同的关系,部分中介限制性政策满意度与教师职业认同的关系。本研究通过社会认知职业理论解释了公费教育政策满意度与教师职业认同的关系路径,为提升公费师范生的教师职业认同提供了参考和借鉴。     

因果变化模式与因果联结强度在幼儿因果推理中的作用

对93名幼儿进行了五种因果变化模式的因果推理题目的测试。结果表明:(1)在不同的因果变化模式下,被试进行因果推理的成绩存在差异,且在对于这五类题目的掌握上具有一定的顺序。(2)被试在同样因果变化模式题目的表现之间具有较高的相似性,而在因果联结强度相同的题目之间则具有显著的差异。(3)被试对于各题目回答的正确率并不随原因与结果联结次数的增多而提高。(4)即使是在观察到的刺激完全一致的情况下,被试的回答仍会因因果变化模式的差异及主试对于题目解释的不同而存在差别。     

Group Intensive Family Training (GIFT) for preschoolers with autism spectrum disorders

Early, intensive behavioral intervention is effective in treating children with autism spectrum disorders (ASDs), but can be cost prohibitive. Expenses may be defrayed if children can benefit from parents acting as therapists. This quantitative case series examines the efficacy of the Group Intensive Family Training (GIFT) program, a 12‐week (180 h, delivered 3 h each weekday) parent‐training for preschoolers with ASDs. Parents were individually mentored in the hands‐on application of behavior analytic techniques, implementing these skills in vivo within a group of six parent–child dyads. Seventy‐two parents and children (ages 25–68 months) with ASDs participated in this study. Children's cognitive and adaptive functioning was assessed before and after the intervention program. Analyses revealed average gains of eight standard score points on the Mullen Early Learning Composite and five standard score points on the Vineland Adaptive Behavior Composite after 12 weeks of treatment. Additionally, 14% and 11% of the children moved from the ‘impaired’ to ‘non‐impaired’ range on Mullen and Vineland composite scores, respectively. This preliminary investigation suggests that GIFT's behavioral, group parent‐training can lead to significant, yet cost‐ and time‐efficient gains for children with ASDs. Results must be interpreted with caution because of the absence of a control group. Copyright © 2008 John Wiley & Sons, Ltd.     

Statistical processing: not so implausible after all

Myczek and Simons (2008) have shown that findings attributed to a statistical mode of perceptual processing can, instead, be explained by focused attention to samples of just a few items. Some new findings raise questions about this claim. (1) Participants, given conditions that would require different focused attention strategies, did no worse when the conditions were randomly mixed than when they were blocked. (2) Participants were significantly worse at estimating the mean size when given small samples than when given the whole display. (3) One plausible suggested strategy--comparing the largest item in each display, rather than the mean size--was not, in fact, used. Distributed attention to sets of similar stimuli, enabling a statistical-processing mode, provides a coherent account of these and other phenomena.
