Delivery of internet treatment for compulsive hoarding (D.I.T.C.H.)

This study tested the effectiveness of an existing private online CBT-based group intervention designed to help people with hoarding. Web-group participants were hypothesized to show more improvement in hoarding symptoms over time compared to those placed on a naturalistic waitlist. This web-based self-help group (N = 106 members, N = 155 waitlisted) includes a formal application process and requires that participants post action steps and progress at least once monthly. Members have access to educational resources on hoarding, cognitive strategies, and a chat-group. Potential research participants were invited to complete an anonymous web-based survey about their hoarding behaviors and clinical improvement on five occasions (3 months apart). The sample was mainly middle-aged, female and White. Regression analyses show that Recent members reported greater improvement and less clutter at 6 months (than Waitlist). Long-term members reported milder hoarding symptoms than Recent ones, suggesting benefits from group participation over time. All members showed reductions in clutter and hoarding symptoms over 15 months. Less posting activity was associated with greater hoarding severity. Online CBT-based self-help for hoarding appears to be a promising intervention strategy that may extend access to treatment. Evaluating the benefits of internet self-help groups is critical given growing popularity of and demand for web-based interventions.     

Are there limits to collectivism? Culture and children's reasoning about lying to conceal a group transgression

This study explored the effects of collectivism on lying to conceal a group transgression. Seven‐, 9‐, and 11‐year‐old US and Chinese children (N=374) were asked to evaluate stories in which protagonists either lied or told the truth about their group's transgression and were then asked about either the protagonist's motivations or justification for their own evaluations. Previous research suggests that children in collectivist societies such as China find lying for one's group to be more acceptable than do children from individualistic societies such as the United States. The current study provides evidence that this is not always the case: Chinese children in this study viewed lies told to conceal a group's transgressions less favourably than did US children. An examination of children's reasoning about protagonists' motivations for lying indicated that children in both countries focused on an impact to self when discussing motivations for protagonists to lie for their group. Overall, results suggest that children living in collectivist societies do not always focus on the needs of the group. Copyright © 2010 John Wiley & Sons, Ltd.     

Anxiety enhances threat processing without competition among multiple inputs: a diffusion model analysis

Enhanced processing of threatening information is a well established phenomenon among high-anxious individuals. This effect is most reliably shown in situations where 2 or more items compete for processing resources, suggesting that input competition is a critical component of the effect. However, it could be that there are small effects in situations without input competition, but the dependent measures typically used are not sensitive enough to detect them. The present study analyzed data from a noncompetition task, single-string lexical decision, with the diffusion model, a decision process model that provides a more direct measure of performance differences than either response times or accuracy alone. The diffusion model analysis showed a consistent processing advantage for threatening words in high-anxious individuals, whereas traditional comparisons showed no significant differences. These results challenge the view that input competition is necessary for enhanced threat processing. Implications for theories of anxiety are discussed.     

Facilitating children's accurate responses: conversational rules and interview style

This study examined the effectiveness of teaching young children a set of social conversational rules as a method of reducing errors in children's memory reports. Forty children (aged 3 to 6 years) interacted with a confederate ‘teaching assistant.’ Three conversational rules were examined as possible means of decreasing inaccuracies. For comparison purposes, three placebo rules were also developed. To test the limitations of teaching young children a set of conversational rules, three interview styles (neutral, repetitive, accusatory) were used. Results indicated that children who received all three target rules provided a smaller proportion of incorrect responses than did children who received fewer target rules or than children in a placebo control group, regardless of interview style. Theoretical and applied issues are discussed. Copyright © 2005 John Wiley & Sons, Ltd.     

Confirmatory Factor Analysis of the Behavioral and Emotional Rating Scale–2 (BERS-2) Parent and Youth Rating Scales

We confirmed the factor structure of the Behavioral and Emotional Rating Scale – 2nd Edition (BERS-2) with a normative parent and youth sample. The BERS-2, based on the Behavioral and Emotional Rating Scale (BERS), is a standardized instrument that assesses children's emotional and behavioral strengths. The original BERS was renormed to create a separate parent scale (Parent Rating Scale) and a youth self-report scale (Youth Rating Scale). In this study, we investigated whether the five-factor structure of the original BERS (i.e., interpersonal strengths, family involvement, intrapersonal strengths, school functioning, and affective strengths) could be replicated with normative parent and youth respondents. A total of 927 parents of students with and without disabilities and 1301 youth with and without disabilities volunteered to participate in the study. Confirmatory factor analysis was used to determine the extent to which the normative parent and youth data fit the original five-factor BERS structure. Results indicated that the five-factor structure demonstrated an acceptable fit with the normative parent and youth samples. Practical implications and future research ideas are discussed.     

Parametric exploration of the Simon effect across visual space.

The Simon effect refers to the performance advantage for responding to the nonspatial identity of the target when the target's irrelevant location corresponds with the relative location of the response. The present study is a parametric examination of the magnitude of the Simon effect across visual space. Response keys were arranged along vertical, horizontal, and two diagonal axes, and stimuli were arranged in two concentric circles (near and far from fixation) along the same axes. The results show that the Simon effect is of similar magnitude regardless of stimulus-response axis. In contrast to findings from stimulus-response compatibility paradigms, there was no evidence in this study for the presence of an orthogonal compatibility effect or left-right prevalence effect, suggesting that these effects only arise when response location is relevant. The results demonstrate the robust generalizability of the Simon effect under different spatial conditions and thus broaden the relevance of the Simon effect to a variety of applications.     

Children's Critical Thinking When Learning From Others

A key component of critical thinking is the ability to evaluate the statements of other people. Because information that is obtained from others is not always accurate, it is important that children learn to reason about it critically. By as early as age 3, children understand that people sometimes communicate inaccurate information and that some individuals are more reliable sources than others. However, in many contexts, even older children fail to evaluate sources critically. Recent research points to the role of social experience in explaining why children often fail to engage in critical reasoning.
