The evolution of problem and social competence behaviors during toddlerhood: A prospective population‐based cohort survey

Research in developmental psychopathology has long been preoccupied with rather broad categories of behavior, but we know little about the specific behaviors that comprise these categories. The objective of this study was to: (a) estimate the prevalence of problem and social competence behaviors in the general population of children at 17 months of age, and (b) describe the continuity and discontinuity in the degree to which children exhibit these behaviors between 17 and 29 months of age. The results show that frequent problem behaviors are not typical of children under two years of age. Further, the results suggest that it is possible to distinguish between different types of problem behaviors before two years of age. In addition, the results show that gender differences in some problem behaviors are already present before two years of age, and increase in magnitude during toddlerhood. Finally, the results show that interindividual differences in problem behaviors observed before two years of age are stable. The predictive accuracy of frequent problem behaviors in children at 17 months of age was limited, however, with often a majority of toddlers not behaving this way a year later. Overall, our results suggest that toddlerhood represents a critical period when behavioral and emotional problems of potentially clinical significance emerge. Pediatricians should routinely ask parents to report the frequency of their young children's problem behaviors during child health supervision visits so that children whose frequent problem behaviors persist over time can be identified and possibly referred for treatment.     

Counterfactual closeness and predicted affect

Empirical research on counterfactual thinking has found a closeness effect: people report higher negative affect if an actual outcome is close to a better counterfactual outcome. However, it remains unclear what actually is a “close” miss. In three experiments that manipulate close counterfactuals, closeness effects were found only when closeness was unambiguously defined either with respect to a contrasted alternative, or with respect to a categorical boundary. In a real task people failed to report greater negative affect when encountering a close numerical miss, while they predicted greater negative affect hypothetically. These results show that counterfactual closeness effects on affect depend on closeness being accessible and unambiguously defined.     

Benchmarking the “Question,Persuade, Refer” Program Against Evaluations of Established Suicide Prevention Gatekeeper Trainings

Gatekeeper training is a common approach for aiding suicidal youth. This study utilizes comparative effectiveness “benchmarks” from established programs to evaluate the Question, Persuade, Refer (QPR) program. The QPR program was implemented with adults (N = 2,389) working in youth‐serving community agencies. Questionnaires assessed suicide prevention knowledge, attitudes, subjective norms, perceived behavioral control, and behaviors. Consistent with benchmarked studies, participants in QPR demonstrated knowledge and suicide prevention behavior gains compared with control groups. Future research should utilize benchmarking methods as a measure of effectiveness, and more thoroughly assess mechanisms that promote behavior change.     

Oxytocin Receptor (OXTR) Single Nucleotide Polymorphisms Indirectly Predict Prosocial Behavior Through Perspective Taking and Empathic Concern

Engaging in prosocial behavior can provide positive outcomes for self and others. Prosocial tendencies contribute to the propensity to engage in prosocial behavior. The oxytocin receptor gene (OXTR) has also been associated with prosocial tendencies and behaviors. There has been little research, however, investigating whether the relationship between OXTR and prosocial behaviors is mediated by prosocial tendencies. This relationship may also vary among different types of prosocial behavior. The current study examines the relationship between OXTR, gender, prosocial tendencies, and both altruistic and public prosocial behavior endorsement. Students at a midwestern university (N = 398; 89.2% Caucasian; M_age = 20.76; 26.6% male) provided self‐report measures of prosocial tendencies and behaviors and buccal cells for genotyping OXTR polymorphisms. Results indicated that OXTR single nucleotide polymorphism (SNP) rs2268498 genotype significantly predicted empathic concern, whereas gender moderated the association between several other OXTR SNPs and prosocial tendencies. Increased prosocial tendencies predicted increased altruistic prosocial behavior endorsement and decreased public prosocial behavior endorsement. Our findings suggest an association between genetic variation in OXTR and endorsement of prosocial behavior indirectly through prosocial tendencies, and that the pathway is dependent on the type of prosocial behavior and gender.     

Public Voices in Pharmaceutical Deliberations: Negotiating “Clinical Benefit” in the FDA’s Avastin Hearing

This article offers a hybrid rhetorical-qualitative discourse analysis of the FDA’s 2011 Avastin Hearing, which considered the revocation of the breast cancer indication for the popular cancer drug Avastin. We explore the multiplicity of stakeholders, the questions that motivated deliberations, and the kinds of evidence presented during the hearing. Pairing our findings with contemporary scholarship in rhetorical stasis theory, Mol’s (2002) construct of multiple ontologies, and Callon, Lascoumes, and Barthe’s (2011) “hybrid forums,” we demonstrate that the FDA’s deliberative procedures elides various sources of evidence and the potential multiplicity of definitions for “clinical benefit.” Our findings suggest that while the FDA invited multiple stakeholders to offer testimony, there are ways that the FDA might have more meaningfully incorporated public voices in the deliberative process. We conclude with suggestions for how a true hybrid forum might be deployed.     

Risk perception and behavior: Pessimism,realism, and optimism about aids-related health behavior

Abstract

This study investigates the perceived risk of becoming infected with HIV for heterosexuals with multiple sexual partners, examines cognitive and motivational antecedents of biases in risk perception, and relates these biases to behavior. We obtained a moderate degree of optimism in a longitudinal study based on a sample of 535 visitors of a STD clinic. Further analyses—after classifying subjects as “pessimists”, “realists”, or “optimists”—revealed that pessimists were extremely pessimistic and optimists remarkably optimistic. Optimism increased with perceived control and decreased with prior experience, supporting a cognitive explanation of optimism. The data also provided some support for a motivational explanation: optimists who scored higher on a defensive coping style were more optimistic about their risks. Contrary to other findings, we found a positive relation between optimism and intentions to reduce risks. Furthermore, results revealed that optimists showed lower levels of subsequent behavioral risk. It was concluded that optimists were not unrealistically optimistic about their personal vulnerability. but rather that pessimists were unrealistically pessimistic. Previous behavior was found to be the best predictor of subsequent behavior. Although measures of perceived risk were also related to subsequent behavior, their predictive power was rather modest.     

Colour constancy in goldfish and man: influence of surround size and lightness

Colour constancy was investigated by using a series of 10 simultaneously presented surface colours ranging in small steps from green through gray to red-purple. Goldfish were trained to select one medium test field when the entire setup was illuminated with white light. In the tests, either red or green illumination was used. Colour constancy, as inferred from the choice behaviour, was perfect under green illumination when the test fields were presented on a gray or a white background, but imperfect on a black background. Under red illumination and a white background, however, colour constancy was overcompensated. Here, a colour contrast effect was observed. The influence of background lightness was also found when the surround was restricted to a narrow annulus of 4-11 mm width (test field diameter: 14 mm). By applying colour metrics it could be shown that the von Kries coefficient law can describe the overall effect of colour constancy. For an explanation of the effect of surround size and lightness, lateral inhibitory interactions have to be assumed in addition, which are also responsible for simultaneous colour contrast. Very similar results were obtained in experiments with the same colours in human subjects. They had to name the test field appearing 'neutral' under the different illumination and surround conditions, as tested in the goldfish experiment.
