Conformity effects in memory as a function of group size,dissenters and uncertainty

In two experimental studies we investigated how false memory reports provided by anonymous group members affect individuals' recognition. Participants were presented with a series of salient and non‐salient objects and recognition memory was subsequently assessed for presented and non‐presented stimuli. In this recognition test, participants were confronted with (in)correct responses from bogus group members. The findings indicate that the bogus answers influenced memory reports only in the absence of a clear recollection and if the stimulus was not judged to be particularly memorable. Moreover, we found no evidence that motivational influences affected participants' judgements. However, the influence of the bogus group decreased with the presence of dissenters who broke the unanimity of the group, and it increased with higher uncertainty.

Agreement Between Parent and Teacher Ratings of Disruptive Behavior Disorders in Children with Clinically Diagnosed ADHD

This study investigated the agreement between parent and teacher ratings of DSM-IV symptoms of Attention Deficit Hyperactivity Disorder (ADHD) and related disorders: Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD). A sample of 55 children in the age range of 6–12 years with clinically diagnosed ADHD participated in the study. Parents and teachers were asked to complete the Disruptive Behavior Disorder Rating Scale (DBDRS; W. E., Pelham, E. M., Gnagy, K. E., Greenslade, & R. Milich, 1992). No association was found between parent and teacher ratings of inattention and hyperactivity/impulsivity. However, moderate to high levels of agreement were obtained for ratings of symptoms that characterized ODD and CD. The observed low levels of agreement between parent and teacher ratings of ADHD symptoms may be attributed to different perceptions of the problem behavior by parents and teachers, medication effects, or the situation specificity of children's behavior. It is recommended that the diagnostic criterion of symptom pervasiveness for the diagnosis of ADHD be operationalized more clearly.     

Predicting future affective states: How ease of retrieval and faith in intuition moderate the impact of activated content

Prior research suggests that duration bias—the tendency to overestimate the duration of affective states—is due to individuals' inordinate focus on event‐related information. We propose that the impact of focusing on event‐related (vs. unrelated) content is moderated by the ease with which the information is brought to mind. In the present experiment, participants thought about a possible future negative event and made affective forecasts after retrieving either few or many aspects in their life that would be affected (or unaffected) by the event. Participants estimated longer duration of affective consequences when they retrieved event‐related rather than event‐unrelated information. However, this effect was restricted to conditions where the respective information was brought to mind easily. Importantly, results also revealed that individual differences in faith in intuition moderated the effect of manipulated ease of retrieval. Copyright © 2008 John Wiley & Sons, Ltd.     

Temperament and Vulnerability to Psychopathology: Introduction to the Special Section

Several authors have highlighted associations with temperament as promising avenues for understanding vulnerability to psychopathology (e.g., Muris and Ollendick, Clinical Child and Family Psychology Review, 8, 271–289, 2005; Nigg, Journal of Child Psychology and Psychiatry, and Allied Disciplines, 47, 395–422, 2006). The successful integration of models of temperament and models of psychopathology will undoubtedly increase our understanding of both. The current special section intends to present important new ideas and evidence in this field and tries to formulate answers to a couple of emerging questions. To set the stage for the papers, we provide a brief state of the art of research on temperament—psychopathology associations. After that, we discuss emerging questions in the field, some of which are addressed in the papers of this special section. To conclude, we point out a couple of future research perspectives.     

Competencies for infant mental health therapists: A survey of expert opinion

We report on data provided by a nationwide panel of 23 infant mental health (IMH) experts who provided numerical ratings of the relative importance of 143 competencies desirable for licensed mental health therapists working with infants/children birth to 5 years of age and their families/caregivers. The competencies were developed based on prior state and national efforts and our own experience in training IMH therapists. The competencies were grouped conceptually into seven areas: (a) Normal infant and toddler development; (b) Atypical development (perturbations in development); (c) Emotional/behavioral disorders in infants and young children; (d) Assessment; (e) Intervention; (f) Community resources and referrals; and (g) Organization, communication, and collaboration. We calculated means, SDs, 95% confidence intervals to rank order each competency. We conducted reliability analyses and tested for mean differences in ratings for the seven areas. Interrater and intraclass correlations were modest, likely the result of restriction of range in the ratings. The seven areas showed high levels of internal consistency and, with few exceptions, did not significantly differ in the means of their ratings. The utility of the competencies are discussed as a framework for training and professional development for IMH clinicians.     

Testing for DIF in a model with single peaked item characteristic curves: The parella model

The PARELLA model is a probabilistic parallelogram model that can be used for the measurement of latent attitudes or latent preferences. The data analyzed are the dichotomous responses of persons to items, with a one (zero) indicating agreement (disagreement) with the content of the item. The model provides a unidimensional representation of persons and items. The response probabilities are a function of the distance between person and item: the smaller the distance, the larger the probability that a person will agree with the content of the item. This paper discusses how the approach to differential item functioning presented by Thissen, Steinberg, and Wainer can be implemented for the PARELLA model.

生物库管理:如何避免失败

近年来,生物库成为了人们关注的焦点,因为生物库已经成为了生物制药和药学研究领域新的必备基础和来源。生物库所承载的历史使命是极具挑战性的,甚至有些令人望而却步:它既要将现有生物样本库转化成基因学研究的新的研究工具,又要建立大规模人群生物库。建立或维护生物库不仅仅是一项简单的收集工作,而是要通过生物库管理来赋予其特定的知识价值,这种知识价值可以产生相应的医疗健康意义或某种经济价值。生物库的成败与否,生物库创造价值的能力,取决于管理体系的确立和有序模式的建立,其建立可以为分类提供策略,并最终建立一个互动的网络体系,这个互动网络体系呈现在一系列不同的领域中:科学/技术领域,医药/卫生领域,产业化经济领域,法律道德和社会政治领域。
