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.     

Trauma and memory: effects of post-event misinformation, retrieval order, and retention interval

The present study concerned effects of misinformation, retrieval order, and retention interval on eyewitness memory for a traumatic event (a vivid murder). Relations between misinformation acceptance and compliance were also examined. The classic three-stage misinformation paradigm (Loftus, 1979) was employed, with a multi-component recognition test added. Either immediately or 2 weeks after viewing a distressing film, 232 adults read a narrative (misleading or control) about the murder and then took a recognition test that tapped memory for central and peripheral details. Test-item order either matched the chronology of the film or was randomly determined. Significant misinformation effects were obtained. Moreover, control participants were more accurate in response to questions about central than peripheral information; however, this was not so for misinformed participants. Sequential but not random retrieval order resulted in a higher proportion of correct responses for central as opposed to peripheral misinformation questions. Compliance was significantly related to misinformation effects. Delay increased participants' suggestibility, impaired memory accuracy, and produced higher confidence ratings for misinformed participants compared to controls. Findings indicate that even for a highly negative event, adults' memory is not immune to inaccuracies and suggestive influences.     

Montserratian mothers’ and English teachers’ perceptions of teaching and learning

After the explosion of a previously dormant volcano in Montserrat (an island in the Caribbean, in the Leeward Islands of the West Indies, overseas territory of the UK) in 1996, about 3000 people emigrated to England. As the children settled into English schools, the pattern of underachievement observed with previous West Indian immigrants started to repeat itself. However, a new fact emerged: Montserratian parents were unhappy with the standards of mathematics and science in English schools, which they considered low. This paper reports a case study of how two Montserratian mothers and their four children perceived English schools. The parents, a Montserratian and an English teacher were interviewed about their views of teaching and learning. The parents were also videotaped while helping their children with homework; the English teacher watched one of these tapes and commented on the session.The interviews and videos were analysed by themes. The interpretation of the themes identified in the interviews was later checked against the events in the homework sessions. Different implicit conceptions of school emerged from the analysis: Montserratian schools appear to fit an ‘interdependent’ style of socialisation whereas English schools fit a more ‘independent’ style. These implicit conceptions of schooling resulted in misunderstandings between teachers and parents, who did not perceive each other as truly helping the children. Differences were also observed in implicit teaching and learning aims. These differences seem to explain the Montserratian parents’ perceptions of a low standard of work being asked of their children in English schools.It is suggested that teachers of immigrant children would find it useful to understand pupils’ and parents’ implicit conceptions of schools when they receive immigrants in their community. Their communication with parents might work better if it fits with the parental expectations and parents have time to learn the ways of schooling in the host country.     

Maternal Antisocial Behavior, Parenting Practices, and Behavior Problems in Boys at Risk for Antisocial Behavior

We investigated the independent contributions of maternal history of antisocial behavior and parenting practices to the worsening course of sons' behavior problems in a sample of young urban boys at risk for antisocial behavior. Mothers reported on boys' behavior problems at baseline and one year later, as well as on their own history of antisocial behavior before and after age 15, and of lifetime depression and substance use disorders (provisional DSM-III-R diagnoses). Baseline reports of parenting practices were obtained. Lower involvement, lower monitoring, and higher levels of parent–child conflict and maternal Conduct Disorder (CD) before age 15 contributed to the worsening of boys' behavior problems one year later; mothers' symptoms of Antisocial Personality Disorder after age 15 did not. Mothers' lifetime history of Major Depression and Substance Use Disorder did not add to the worsening of boys' behavior problems after accounting for these other factors. Although maternal CD contributed directly to the worsening of boys' behavior problems, the effect of parenting was more substantial. We discuss clinical implications for prevention and treatment of children's antisocial behavior, and intergenerational implications of girls' early antisocial behavior.
