The matching relation and situation-specific bias modulation in professional football play selection

The utility of a quantitative model depends on the extent to which its fitted parameters vary systematically with environmental events of interest. Professional football statistics were analyzed to determine whether play selection (passing versus rushing plays) could be accounted for with the generalized matching equation, and in particular whether variations in play selection across game situations would manifest as changes in the equation's fitted parameters. Statistically significant changes in bias were found for each of five types of game situations; no systematic changes in sensitivity were observed. Further analyses suggested relationships between play selection bias and both turnover probability (which can be described in terms of punishment) and yards-gained variance (which can be described in terms of variable-magnitude reinforcement schedules). The present investigation provides a useful demonstration of association between face-valid, situation-specific effects in a domain of everyday interest, and a theoretically important term of a quantitative model of behavior. Such associations, we argue, are an essential focus in translational extensions of quantitative models.     

A Randomized Trial of Two Promising Computer-Based Interventions for Students with Attention Difficulties

Few studies have examined whether attention can be improved with training, even though attention difficulties adversely affect academic achievement. The present study was a randomized-controlled trial evaluating the impact of Computerized Attention Training (CAT) and Computer Assisted Instruction (CAI) on attention and academic performance in 77 inattentive first graders. Students receiving either intervention were more likely than controls to show a moderate decline in teacher rated attention problems in first grade. Students receiving CAI also showed gains in reading fluency and in teacher ratings of academic performance. Intervention effects for attention were absent by second grade largely because attention problems declined in all groups. However, post hoc analyses indicated potential longer-term benefits for children with 6 or more inattentive symptoms at baseline. Persistent attention problems were associated with poorer academic performance in multiple domains. Results provide initial evidence that CAT and CAI can improve children’s attention in the classroom - and support additional studies to determine whether more clinically significant benefits are attainable.     

Relational Aggression and Hostile Attribution Biases: Testing Multiple Statistical Methods and Models

The present study used both categorical and dimensional approaches to test the association between relational and physical aggression and hostile intent attributions for both relational and instrumental provocation situations using the National Institute of Child Health and Human Development longitudinal Study of Early Child Care and Youth Development (M = 8.3 years-old, SD = 0.19, N = 840). A one standard deviation threshold was used to create categorical aggression status groups. In categorical analyses, children who were both relationally and physically aggressive were found to attribute more hostile intent attributions in relationally provocative situations. Results from the dimensional analyses indicated that female gender, physical aggression, and hostile attribution biases for instrumental provocations each predicted increases in relational aggression over time. Further, relational aggression was not predictive of hostile attribution biases for relational provocations, and instead physical aggression was predictive. Implications for the fields of developmental psychology and psychopathology are discussed.     

Sex differences in relational and overt aggression in the late elementary school years

Sex differences in relational and overt aggression among 3rd (n=176), 4th (n=179), and 5th graders (n=145) from three public schools (n=500; 278 girls) were examined. Nominations of relational aggression increased over time among 4th and 5th grade girls, but not among boys or 3rd grade girls. Among 3rd graders, boys received more nominations for relational aggression than girls. By the end of the 5th grade, girls received more relational aggression nominations than boys. There was also a significant rise in nominations of overt aggression among 5th grade girls, but not among 5th grade boys or younger boys and girls. As expected, boys were more likely than girls to be nominated for overt aggression at all grade levels. The findings are helpful for explaining inconsistencies of earlier research pertaining to sex differences in relational aggression and for advancing our understanding of the causes of aggression.

Origins of Mothers' and Fathers' Beliefs about Infant Crying

Origins of mothers' and fathers' beliefs about infant crying were examined in 87 couples. Parents completed measures of emotion minimization in the family of origin, depressive symptoms, empathy, trait anger, and coping styles prenatally. At 6 months postpartum, parents completed a self-report measure of their beliefs about infant crying. Mothers endorsed more infant-oriented and less parent-oriented beliefs about crying than did fathers. Consistent with prediction, a history of emotion minimization was linked with more parent-oriented and fewer infant-oriented beliefs about infant crying for both mothers and fathers either as a main effect or in conjunction with the partners' infant-oriented beliefs. Contrary to expectation, parents' own emotional dispositions had little effect on parents' beliefs about crying. The pattern of associations varied for mothers and fathers in a number of ways. Implications for future research and programs promoting sensitive parenting are discussed.     

The Psychometric Properties of the Personality Assessment Inventory-Short Form (PAI-SF) in Inpatient Forensic and Civil Samples

Research focusing on the Personality Assessment Inventory (PAI) has increased substantially over the past decade. However, there has been relatively little focus on the PAI short-form (PAISF). The current study evaluated the psychometric characteristics of the PAI-SF clinical scales using participants admitted to a large northeastern hospital under forensic (N?=?178) and civil (N?=?320) statutes. Results indicate that the internal consistency of the PAI-SF clinical scales is adequate for both the Forensic (range of alphas: 0.74 to 0.88) and Civil (0.79 to 0.91) samples, and assumptions of item-scale convergence and divergence were generally met with some exceptions. Finally, the PAI-SF exhibited strong agreement with the full-form PAI scores overall, and at the upper extreme (T?≥?70) of the distributions for both samples. The results are discussed in terms of how they extend prior research on the PAI-SF.     

Dynamic Stereotypes of Power: Perceived Change and Stability in Gender Hierarchies

Despite widespread change in gender roles, women continue to have less power than men. From the perspective of social role theory, this gender difference in power should be perceived as eroding as women gain access to male-dominated roles typically associated with power. Study 1's open-ended reports nearly unanimously projected an increase in women's power over the next 50 years, whereas responses were equally split between projecting stability or a decrease in men's power. Study 2's quantitative findings illustrated that participants perceived women as gaining in political, economic, occupational, individual, and relational power from the past into the future. In contrast, men were perceived as decreasing in relational power but maintaining levels of other forms of power over time. Despite the projections of increases in women's power, women were not projected to reach parity with men by 2050. We examine the implications of these beliefs for future social change.     

Positive Affectivity and Collective Efficacy as Moderators of the Relationship Between Perceived Politics and Job Satisfaction

This study explores the moderating potential of positive affectivity (PA) and perceived collective efficacy (PCE) on the relationship between 3 dimensions of politics perceptions and job satisfaction. We hypothesized that high levels of PA and PCE, in unison, would buffer the harmful effects of perceived politics on job satisfaction. Regression analyses for the 3 dimensions (i.e., general politics, go along to get along, and pay and promotion) yielded a significant finding for the PA × PCE × Go Along to Get Along 3-way interaction only. Consistent with our expectations, low PA-low PCE individuals were less satisfied with their jobs when levels of go-along-to-get-along politics increased. Contrary to our hypothesis, however, high PA-high PCE individuals reported a significant inverse relationship between perceived politics and job satisfaction. Implications of these findings and directions for future research are provided.
