Individual differences in children's emotion understanding: effects of age and language

Over the last two decades, it has been established that children's emotion understanding changes as they develop. Recent studies have also begun to address individual differences in children's emotion understanding. The first goal of this study was to examine the development of these individual differences across a wide age range with a test assessing nine different components of emotion understanding. The second goal was to examine the relation between language ability and individual differences in emotion understanding. Eighty children ranging in age from 4 to 11 years were tested. Children displayed a clear improvement with age in both their emotion understanding and language ability. In each age group, there were clear individual differences in emotion understanding and language ability. Age and language ability together explained 72% of emotion understanding variance; 20% of this variance was explained by age alone and 27% by language ability alone. The results are discussed in terms of their theoretical and practical implications.     

Self-reported delinquency among Alberta's youth: findings from a survey of 2,001 junior and senior high school students

This article draws on data from a 1999 survey on youth victimization, crime and delinquency in Alberta conducted by the Canadian Research Institute for Law and the Family in collaboration with researchers from the University of Alberta. The survey included 2,001 youth attending Grades 7 to 12 in public and Catholic schools in selected urban and rural areas in the province. Analyses focus on self-reported past-year delinquency. Statistically significant results were found for relationships between extent of delinquency and gender, grade level, psychosocial problems (as measured by conduct, hyperactivity, and emotional problems), and extent of past-year victimization. For low/moderate delinquency, females were comparable to males, and even reported slightly higher rates for low/moderate violence-related delinquency. Younger students were more likely to indicate engaging in violence-related delinquency, while older students were more likely to report property-related delinquent acts. Overall, Grade 9 students had the highest rates of delinquency. For personal characteristics, a high score on conduct problems was most strongly correlated with moderate/high delinquency. The relationship between high levels of delinquency and victimization was stronger for violence-related delinquency than for property-related delinquency.     

Visual influences on the internal structure of phonetic categories

Previous work has demonstrated that the graded internal structure of phonetic categories is sensitive to a variety of contextual factors. One such factor is place of articulation: The best exemplars of voiceless stop consonants along auditory bilabial and velar voice onset time (VOT) continua occur over different ranges of VOTs (Volaitis & Miller, 1992). In the present study, we exploited the McGurk effect to examine whether visual information for place of articulation also shifts the best exemplar range for voiceless consonants, following Green and Kuhl's (1989) demonstration of effects of visual place of articulation on the location of voicing boundaries. In Experiment 1, we established that /p/ and /t/ have different best exemplar ranges along auditory bilabial and alveolar VOT continua. We then found, in Experiment 2, a similar shift in the best-exemplar range for /t/ relative to that for /p/ when there was a change in visual place of articulation, with auditory place of articulation held constant. These findings indicate that the perceptual mechanisms that determine internal phonetic category structure are sensitive to visual, as well as to auditory, information.     

Disconfirming intergroup evaluations: asymmetric effects for in-groups and out-groups

The authors examined whether a fundamental bias in the way people process information has implications for efforts to improve intergroup relations. The authors exposed participants to information about their own social category and a different social category that was either positive or negative in connotation. To examine what effect this information would have on participants' attitudes toward their own group and the other group, the authors measured both explicit and implicit evaluations before and after exposure. The findings suggest that, at a preconscious level, exposure to negative information affects participants' attitudes toward their own group, but that positive information has a negligible impact on attitudes toward other groups. The authors found an opposite pattern for explicit (conscious) evaluations. These asymmetries are consistent with cognitive and motivational theory on intergroup relations and may have important implications for efforts to reduce prejudice.     

Effects of stress typicality during spoken word recognition by native and nonnative speakers of English: Evidence from onset gating

Onset gating was used to investigate the effects of stress typicality during the processing of disyllabic nouns and verbs by 34 native and 36 nonnative speakers of English. We utilized 50-msec increments and included two conditions. In the silenced condition, only word onsets were presented (the participants had no information about the duration or stress pattern of the entire word). In the filtered condition, word onsets were presented with a low-pass filtered version of the remainder of the word (this type of filtering provides duration and stress information in the absence of phonemic information). The results demonstrated significant effects of stress typicality in both groups of speakers. Typically stressed trochaic nouns and iambic verbs exhibited advantaged processing, as compared with atypically stressed iambic nouns and trochaic verbs. There was no significant effect of presentation condition (silenced or filtered). The results are discussed in light of recent research in which the effects of lexical stress during spoken word recognition have been investigated.     

Nine Months of Multicomponent Behavioral Treatment for ADHD and Effectiveness of MTA Fading Procedures

We examined 9-month data from the 14-month NIMH Multimodal Treatment Study of Children with ADHD (the MTA) as a further check on the relative effect of medication (MedMgt) and behavioral treatment (Beh) for attention-deficit/hyperactivity disorder (ADHD) while Beh was still being delivered at greater intensity than at 14-month endpoint, and conversely as a check on the efficacy of the MTA behavioral generalization/maintenance procedures. Intention-to-treat analysis at 9 months showed essentially the same results as at 14 months, after Beh had been completely faded; MedMgt and the combination (Comb) of medication and Beh were significantly superior to Beh and community care (CC) for ADHD and oppositional-defiant (ODD) symptoms, with mixed results for social skills and internalizing symptoms. All treatment-group differences examined as changes in slopes from 9 to 14 months were nonsignificant (we found general improvement for all groups). Slopes from baseline to 9 months correlated highly (r > .74, p < .0001) with slopes from baseline to 14 months for all groups. The time function from baseline to 14 months showed a significant linear, but not quadratic, trend for the main outcome measure (a composite of parent- and teacher-rated ADHD and ODD symptoms) for all groups. Findings suggest that in contrast to the hypothesized deterioration in the relative benefit of Beh between 9 and 14 months (after completion of fading), the MTA Beh generalization and maintenance procedures implemented through 9 months apparently yielded continuing improvement through 14 months, with preservation of the relative position of Beh compared to other treatment strategies.     

A Strengths-Based Consultancy Approach in Elite Sport: Exploring Super-Strengths

There is a lack of literature documenting strengths-based approaches in sport psychology. This study explored how a super-strengths approach has been implemented by sport psychologists (n = 7) and coaches (n = 8), with UK elite athletes. Findings were categorized into 3 general dimensions: defining super-strengths, identification methods, and phases of development. Super-strengths were defined as a strategy for performance, utilizing a potential world's-best resource to gain a competitive edge. Identification methods were subjective (e.g., asking/observing athletes) and objective (e.g., performance analysis). Participants emphasized 3 development phases: preparation, adaptation and monitoring. Findings offer considerations for implementing a strengths-based approach and future research.     

Social identity and the attitude–behaviour relationship: effects of anonymity and accountability

Two experiments examined the impact of anonymity and accountability on the expression of group‐mediated attitude‐behaviour consistency. In Study 1, low and high identifiers (N = 106) were exposed to an attitude‐congruent norm and provided information about their intentions under anonymous and in‐group accountable conditions. In Study 2, salience of identity was manipulated, and participants (N = 185) were exposed to either an attitude‐congruent or an attitude‐incongruent norm, and provided information on their intentions and behaviour under anonymous and in‐group accountable conditions. In both studies, accountability elicited group‐normative attitudes and behaviour among individuals for whom the group was not a salient basis for self‐definition. When the group was a salient basis for self‐definition, the expression of attitude‐consistent intentions and behaviour was greater in anonymous conditions. It is suggested that strategic effects, such as those that occur in the presence of an in‐group audience, influence displays of group‐normative attitude–behaviour consistency.

Introducing systems change in the schools: the case of school luncheons and vending machines

A major public health crisis facing America’s society is the increase in child and youth obesity, which has seen a fourfold increase in the last four decades. Major concerns include what children eat for school lunch and what other foods are available in schools. This paper illustrates efforts towards systems change in the luncheon program and food vending machines in the Chicago Public Schools. We discuss the different factors that lead to such changes using the framework of the social ecological model and the soft systems methodology, and we analyze how the resulting innovation was implemented and evaluated. First, we present a theoretical perspective to explain factors that influence children’s eating patterns from a systems approach. Second, we discuss the antecedent factors that lead to systems change. Finally, we examine challenges to systems change, such as resistance to change, different stakeholder priorities, lack of resources, institutional bureaucracy, and unrealistic funder expectations.
