Predictors of Externalizing Behavior Problems in Early Elementary-Aged Children: The Role of Family and Home Environments

As children enter elementary school they display behavioral orientations that reveal potential developmental trajectories. Developmental transitions offer unique opportunities for examining developmental pathways and the factors that influence emerging pathways. The primary goal of this investigation was to examine characteristics of family and home contexts in predicting externalizing behavior problems among children transitioning into elementary school. Dimensions of the family and home environments of maltreated and nonmaltreated children (N = 177) were examined and used to predict externalizing behavior problems. Maltreatment was assessed using case file information, characteristics of the family and home environment were rated by interviewers, and externalizing behavior was assessed by mother's ratings on the Child Behavior Checklist. Relative to nonmaltreated children, the family environments of physically abused children were characterized by higher levels of negative social interactions. Also, in comparison to nonmaltreated children, the home environments of children who experienced neglect were characterized as less organized and clean. Hierarchical regression analyses revealed that physical abuse was the strongest predictor of externalizing behavior. After controlling for the contribution of physical abuse, mother's negative behavior toward the focal child, aggression between siblings, and the lack of an organized and clean home were each predictive of externalizing behavior.     

Evolution,green beards,and skin hue wage discrimination

This paper provides an evolutionary rationale for both interracial and intraracial wage differentials by examining the implications of white employers mediating their employer‐employee relationships on the basis of genetic similarity. If in organized labor markets; relationships mediated through genetic similarity are optimal in terms of Darwinian fitness, a fundamental evolutionary implication is that the Marginal Rate of Substitution (MRS) in Darwinian fitness holding extended fitness constant equals the MRS in preferences holding utility constant. Given such an evolutionary equilibrium, results are derived showing that the strength of tastes for discrimination depends upon the skin hue of non‐white workers. The rationale established for racial wage differentials is that where skin hue serves to indicate genetic similarity between employer and employee, wage differentials emerge that are a function of skin hue.

Degeneracy and cognitive anatomy

Cognitive models indicate that there are multiple ways of completing the same task. This implicit degeneracy cannot be revealed by functional imaging studies of normal subjects if more than one of the sufficient neural systems is activated. Nor can it be detected by neuropsychological studies of patients because their performance might not be impaired when only one degenerate system is damaged. We propose that degenerate sets of sufficient neural systems can only be identified by an iterative approach that integrates the lesion-deficit model and functional imaging studies of normal and neurologically damaged subjects.     

Wishful thinking in the prediction of competitive outcomes

In each of two experiments, college students were assigned to two ad hoc groups (Team A and Team B) that competed in a dart-throwing contest. On each trial, one contestant from each team threw a single dart at a standard dart board, trying to come as close as possible to hitting the bull's-eye. Also on each trial, the other participants judged the likelihood that both the Team A contestant and the Team B contestant would come closer to hitting the bull's-eye. In both experiments (N=36 in Experiment 1; N=35 in Experiment 2), participants exhibited a strong wishful thinking effect. They judged the likelihood that their own team members would come closer to be greater than the likelihood that the opposing team members would come closer. Experiment 2 suggested that it was participants' desires, as opposed to some other variable associated with team membership, that influenced their predictions. Experiment 2 also showed that the size of the effect did not depend on whether participants believed that their predictions had been influenced by their team membership. These results help bridge the gap between previous experimental laboratory studies, which have produced inconsistent results, and correlational field studies of sports fans and voters, which have consistently produced large effects.     

Self-Regulated Learning in Younger and Older Adults: Does Aging Affect Metacognitive Control?

ABSTRACT

Two experiments examined whether younger and older adults' self-regulated study (item selection and study time) conformed to the region of proximal learning (RPL) model when studying normatively easy, medium, and difficult vocabulary pairs. Experiment 2 manipulated the value of recalling different pairs and provided learning goals for words recalled and points earned. Younger and older adults in both experiments selected items for study in an easy-to-difficult order, indicating the RPL model applies to older adults' self-regulated study. Individuals allocated more time to difficult items, but prioritized easier items when given less time or point values favoring difficult items. Older adults studied more items for longer but realized lower recall than did younger adults. Older adults' lower memory self-efficacy and perceived control correlated with their greater item restudy and avoidance of difficult items with high point values. Results are discussed in terms of RPL and agenda-based regulation models.     

Strategic control in AGL is not attributable to simple letter frequencies alone

In Norman, Price, and Jones (2011), we argued that the ability to apply two sets of grammar rules flexibly from trial to trial on a “mixed-block” AGL classification task indicated strategic control over knowledge that was less than fully explicit. Jiménez (2011) suggested that our results do not in themselves prove that participants learned – and strategically controlled – complex properties of the structures of the grammars, but that they may be accounted for by learning of simple letter frequencies. We first explain why our main conclusions regarding strategic control and conscious awareness are a separable issue to this criticism. We then report additional data which show that our participants’ ability to discriminate between the two grammars was not attributable to differences in simple letter frequencies.
