Grain Size and Parameter Recovery with TIMSS and the General Diagnostic Model

The purpose of this study was to explore the degree of grain size of the attributes and the sample sizes that can support accurate parameter recovery with the General Diagnostic Model (GDM) for a large-scale international assessment. In this resampling study, bootstrap samples were obtained from the 2003 Grade 8 TIMSS in Mathematics at varying sample sizes from 500 to 4000 and grain sizes of the attributes from a unidimensional model to one with ten attributes. The results showed that the eight-attribute model was the one most consistently identified as best fitting. Parameter estimation for more than ten attributes and samples less than 500 failed. Furthermore, the precision of item parameter recovery decreased as the number of attributes measured by an item increased and sample size decreased. On the other hand, the distributions of latent classes were relatively stable across all models and sample sizes.     

On the transcendental undercurrents of phenomenology: the case of the living body

The Career Development of Adolescent Mothers: A Review of 25 Years of Professional Literature

Twenty‐one articles from peer‐reviewed journals published over 25 years (1983–2008) were selected for inclusion in a review of the professional literature on adolescent mothers' career development. Findings identified that the selected literature included a variety of research methods and theoretical approaches, identified areas of need for this population, and discussed impediments to the career development of adolescent mothers. The most frequent recommendations, aside from the need for further research, were to develop and implement comprehensive programs for adolescent mothers that are strength based and responsive to their needs, and to foster career development skills/knowledge and resiliency.     

Implicit race bias revisited: On the utility of task context in assessing implicit attitude strength

Decades of research have shown that many people harbor implicit attitudes that are positive toward Whites relative to Blacks. With some notable exceptions, these findings are almost always obtained using implicit attitude tasks that assess attitudes toward Whites and Black simultaneously. This makes it difficult to determine whether implicit race bias effects are the result of strong liking for Whites, dislike for Blacks, or both. The present article reports results from a study in which participants' automatic bias towards Blacks and Whites is assessed across multiple evaluative contexts. Results show consistent negative automatic attitudes towards Blacks, but there was considerable variability in participants' attitudes toward Whites. Consistent with the idea that strong attitudes are less contextually sensitive than weaker attitudes (e.g. Krosnick, 1988), it is concluded that participants harbor strong automatic bias against Blacks, but not strong favoritism for Whites. Implications for a context-centered approach to implicit attitude measurement are discussed.     

TRIAL-BASED FUNCTIONAL ANALYSIS AND FUNCTIONAL COMMUNICATION TRAINING IN AN EARLY CHILDHOOD SETTING

Problem behavior is common in early childhood special education classrooms. Functional communication training (FCT; Carr & Durand, 1985 ) may reduce problem behavior but requires identification of its function. The trial‐based functional analysis (FA) is a method that can be used to identify problem behavior function in schools. We conducted trial‐based FAs and FCT with 3 children in an early childhood special education setting. All trial‐based FAs resulted in identification of behavioral functions, and subsequent FCT led to reductions in problem behavior and increases in communication.     

Repulsed by violence: disgust sensitivity buffers trait, behavioral, and daily aggression

Many models of aggression include negatively valenced emotions as common elicitors of aggressive behavior. Yet, the motivational direction of these emotions is not taken into account. The current work explored whether sensitivity to a negative emotion associated with behavioral avoidance-disgust-will predict lower levels of aggression. Five studies tested the hypothesis that disgust sensitivity predicts less aggression. In Study 1 (N = 92), disgust sensitivity predicted less trait physical and verbal aggression. In Study 2 (N = 268), participants high in disgust sensitivity were less likely to behave aggressively towards a stranger on a reaction-time task. In Study 3 (N = 51), disgust sensitivity was associated with less intimate partner violence inclinations. Study 4 (N = 247) replicated this effect longitudinally. In Study 5 (N = 166), each domain of disgust (i.e., moral, sexual, and pathogen disgust) had a buffering effect on daily aggression when daily experiences activated those specific domains. These results highlight the usefulness of considering the motivational direction of an emotion when examining its influence on aggression.     

Behavioral training and predisposed coping strategies interact to influence resilience in male Long-Evans rats: implications for depression

Effective coping strategies and adaptive behavioral training build resilience against stress-induced pathology. Both predisposed and acquired coping strategies were investigated in rats to determine their impact on stress responsiveness and emotional resilience. Male Long-Evans rats were assigned to one of the three coping groups: passive, active, or variable copers. Rats were then randomly assigned to either an effort-based reward (EBR) contingent training group or a non-contingent training group. Following EBR training, rats were tested in appetitive and stressful challenge tasks. Physiological responses included changes in fecal corticosterone and dehydroepiandrosterone (DHEA) metabolites as well as neuropeptide Y (NPY)-immunoreactivity in the hippocampus and amygdala. Regardless of a rat's predisposed coping strategy, EBR rats persisted longer than non-contingent rats in the appetitive problem-solving task. Furthermore, training and coping styles interacted to yield the seemingly most adaptive DHEA/corticosterone ratios in the EBR-trained variable copers. Regardless of training group, variable copers exhibited increased NPY-immunoreactivity in the CA1 region.     

Parenting style and adolescent smoking cognitions and behaviour

Parenting style and smoking-related cognitions have both successfully predicted adolescent smoking behaviour. Data were collected among 482 Dutch adolescents to examine whether effects of parenting styles (authoritative, permissive, authoritarian, rejecting, neglecting, measured by underlying dimensions support, strict control, and psychological control) on adolescent lifetime smoking were mediated by cognitions (pro-smoking attitude, social norm, self-efficacy, intention) and to study the role of gender in this process. Support was not significantly associated with smoking behaviour. The inverse relation between strict control and smoking was partly mediated by attitude and intention, both associated with increased smoking. Psychological control related directly to increased lifetime smoking. Combinations of dimensions creating the specific styles were not associated with cognitions or behaviour. Maternal and paternal parenting were equally associated with smoking cognitions and behaviour; nor were effects moderated by adolescent gender. Interventions to prevent adolescent smoking initiation should aim at increasing strict control and reducing psychological control.
