Parenting Behavior and Conduct Problems in Children with and Without Attention-Deficit/Hyperactivity Disorder (ADHD): Moderation by Callous-Unemotional Traits

There is evidence that negative parenting positively predicts oppositional defiant disorder (ODD) and conduct disorder (CD) and that children’s callous-unemotional (CU) traits may moderate this association. However, it is largely unknown if CU traits show similar interactive effects with positive parenting for ODD/CD. 208 ethnically diverse (56% Caucasian) 6–9 year-old children with and without attention-deficit/hyperactivity disorder (ADHD) were ascertained using multiple methods and informants for ODD, CD, and CU traits. CU traits, corporal punishment, positive parenting, and each of their interactions with CU traits were unrelated to parent- and teacher-rated ODD. Corporal punishment and CU traits were similarly unrelated to parent- and teacher-rated CD. However, positive parenting inversely predicted parent-reported CD symptoms and it was significantly moderated by CU traits. Positive parenting was negatively associated with CD at low to moderate levels of CU traits, but it was unrelated to CD at high levels of CU traits. Children with elevated levels of CU traits exhibited significantly higher levels of CD symptoms that were largely independent of positive parenting behavior. We discuss these findings within a developmental psychopathology framework to provide further perspectives on reciprocal influences between parenting behavior and CU traits in the development of ODD and CD.     

Interference of spoken word recognition through phonological priming from visual objects and printed words

Three cross-modal priming experiments examined the influence of preexposure to pictures and printed words on the speed of spoken word recognition. Targets for auditory lexical decision were spoken Dutch words and nonwords, presented in isolation (Experiments 1 and 2) or after a short phrase (Experiment 3). Auditory stimuli were preceded by primes, which were pictures (Experiments 1 and 3) or those pictures’ printed names (Experiment 2). Prime–target pairs were phonologically onset related (e.g., pijl–pijn, arrow–pain), were from the same semantic category (e.g., pijl–zwaard, arrow–sword), or were unrelated on both dimensions. Phonological interference and semantic facilitation were observed in all experiments. Priming magnitude was similar for pictures and printed words and did not vary with picture viewing time or number of pictures in the display (either one or four). These effects arose even though participants were not explicitly instructed to name the pictures and where strategic naming would interfere with lexical decision making. This suggests that, by default, processing of related pictures and printed words influences how quickly we recognize spoken words.     

Investigating the Role of Emotion in Science Center Visitor Learning

ABSTRACT

A number of investigators have argued that emotion plays an important role in free-choice learning in settings such as museums, science centers, zoos, and aquariums, particularly given the relationship between emotion and cognition. Despite considerable research on the cognitive aspects of visits, empirical studies on emotion in such settings are virtually non-existent. This study investigated the role that emotion plays in facilitating and enhancing learning at a science center. Three major research questions were addressed: (a) Can emotion be measured using Russell's Affect Grid in a non-laboratory setting such as an interactive science center? (b) If so, do different types of science center experiences create measurably different levels of emotional arousal and/or valence in visitors? and (c) If so, was there evidence that elevated arousal and/or valence enhanced or retarded visitors' long-term cognitive science learning? The study provided evidence that emotion could be measured using a modified Affect Grid technique and that a particular traveling exhibition generated arousal levels above baseline levels as determined by a control group. Findings suggest a relationship between emotional arousal and positive changes in visitor long-term cognition, attitudes, and behaviors.     

Personality Factors Related to Black Teenage Pregnancy and Abortion

Forty-eight pregnant adolescents who applied for therapeutic abortions (TAs) were compared with 55 adolescents who planned to have their babies (Terms) and 67 adolescents who were not pregnant (Controls) on the California Psychological Inventory (CPI). All the subjects were single, Black, and aged 15 or 16. CPI results point to psychological differences with the Controls being most socialized, followed by the TAs, and then the Terms. Term girls seem to be experiencing a void and appear to be trying to fill it and assume an adult role by having a baby; the TAs do not seem to have these same needs. In addition, girls who became pregnant and described the relationship with the putative father as casual, appear on the CPI to have more daily problems, lack socialization, be less clear thinking, and have poor self-control. Pregnant girls who have good communication with their mothers showed no differences on the CPI from girls with poor communication with their mothers.     

The anchoring bias reflects rational use of cognitive resources

Cognitive biases, such as the anchoring bias, pose a serious challenge to rational accounts of human cognition. We investigate whether rational theories can meet this challenge by taking into account the mind’s bounded cognitive resources. We asked what reasoning under uncertainty would look like if people made rational use of their finite time and limited cognitive resources. To answer this question, we applied a mathematical theory of bounded rationality to the problem of numerical estimation. Our analysis led to a rational process model that can be interpreted in terms of anchoring-and-adjustment. This model provided a unifying explanation for ten anchoring phenomena including the differential effect of accuracy motivation on the bias towards provided versus self-generated anchors. Our results illustrate the potential of resource-rational analysis to provide formal theories that can unify a wide range of empirical results and reconcile the impressive capacities of the human mind with its apparently irrational cognitive biases.
