Acute Clinical Recovery from Sport-Related Concussion

Concussion is a highly prevalent injury in contact and collision sports that has historically been poorly understood. An influx of sport-concussion research in recent years has led to a dramatic improvement in our understanding of the injury’s defining characteristics and natural history of recovery. In this review, we discuss the current state of knowledge regarding the characteristic features of concussion and typical acute course of recovery, with an emphasis on the aspects of functioning most commonly assessed by clinicians and researchers (e.g., symptoms, cognitive deficits, postural stability). While prototypical clinical recovery is becoming better understood, questions remain regarding what factors (e.g., injury severity, demographic variables, history of prior concussions, psychological factors) may explain individual variability in recovery. Although research concerning individual differences in response to concussion is relatively new, and in many cases limited methodologically, we discuss the evidence about several potential moderators of concussion recovery and point out areas for future research. Finally, we describe how increased knowledge about the negative effects of and recovery following concussion has been translated into clinical guidelines for managing concussed athletes.     

Self-handicapping, excuse making, and counterfactual thinking: consequences for self-esteem and future motivation

Researchers interested in counterfactual thinking have often found that upward counterfactual thoughts lead to increased motivation to improve in the future, although at the cost of increased negative affect. The present studies suggest that because upward counterfactual thoughts indicate reasons for a poor performance, they can also serve as excuses. In this case, upward counterfactual thoughts should result in more positive self-esteem and reduced future motivation. Five studies demonstrated these effects in the context of self-handicapping. First, upward counterfactual thinking was increased in the presence of a self-handicap. Second, upward counterfactual thoughts indicating the presence of a self-handicap protected self-esteem following failure. Finally, upward counterfactual thoughts that protect self-esteem reduced preparation for a subsequent performance as well as performance itself. These findings suggest that the consequences of upward counterfactuals for affect and motivation are moderated by the goals of the individual as well as the content of the thoughts.     

When mutations meet motivations: Attitude biases in counterfactual thought

The present research examines whether existing attitudes can spontaneously bias the content and direction of generated counterfactual thoughts, and whether these thoughts influence subsequent attitude-relevant judgments. Two experimental studies demonstrate that attitudes can bias the content of counterfactual thoughts, and that these biased thoughts in turn predict polarized attitudes. These effects were obtained regardless of whether explicit instructions for counterfactual generation were given. Furthermore, both studies demonstrate that these effects are mediated by judgments of future likelihood. Implications of these results for theories of counterfactual thinking and persuasion are discussed.     

Counterfactual thinking following negative outcomes: evidence for group and self-protective biases

Despite the robustness of self-serving and group-serving biases in attribution, there has been only limited evidence for these effects in counterfactual thinking. The present studies demonstrate that, following a negative outcome, individuals counterfactualize external factors relatively more than internal factors when they are identified with the target (i.e. ingroup members or the self) than when they are not. However, these effects are found only for external factors that are in some way disadvantageous to the target and could have led to the negative outcome. Implications of these findings for understanding the relationship between counterfactual thinking and judgments of causality, blame and affect are discussed.

Variable-image videoconfrontation as a method of assessing body image: a technical report and comparison with similar techniques

In this study a new modified videosystem, designed for measuring body-image, was evaluated alongside the major size-estimation measure, namely, the visual size-estimation apparatus. The advantages afforded by a videosystem which allows independent adjustment of size and height/width proportions were highlighted, and its validity and reliability were examined, based on estimates made by obese, normal weight, and pregnant groups.

Jury decision making research: Are researchers focusing on the mouse and not the elephant in the room?

The concerns of jury research have extensively focused on subject selection, yet larger issues loom. We argue that observed differences between students and non-students in mock juror studies are inconsistent at best, and that researchers are ignoring the more important issue of jury deliberation. We contend that the lack of information on deliberating jurors and/or juries is a much greater threat to ecological validity and that some of our basic findings and conclusions in the literature today might be different if we had used juries, not non-deliberating jurors, as the unit of measure. Finally, we come full circle in our review and explore whether the debate about college and community samples might be more relevant to deliberating versus non-deliberating jurors.     

Criminal Behavior and Self-Control: Using the Dual Component Theory of Inhibition Regulation to Advance Self-Control and Crime Research

Predicting crime remains a central issue for social science research. Perspectives that consider the role of self-control have added greatly to our ability to explain and predict criminal behavior. However, this approach has been narrowly focused on the role of individual differences in trait self-control, limiting the potential of this approach to integrate a range of findings in the literature. To realize the full potential of the self-control construct to explain criminal behavior, we use the Dual Component Theory of Inhibition Regulation (DCTIR). We discuss how the model can account for a number of findings, including patterns of recidivism, age differences, and the role of socioeconomic factors in crime. The DCTIR provides a framework for integrating these findings, generating new predictions, and ultimately better predicting criminal behavior.     

Relations of singing talent with voice onset time of trained and untrained female singers

This study examined phonatory-articulatory timing during sung productions by trained and untrained female singers with and without singing talent. 31 untrained female singers were divided into two groups (talented or untalented) based on the perceptual judgments of singing talent by two experienced vocal instructors. In addition to the untrained singers, 24 trained female singers were recorded singing America the Beautiful, and voice onset time was measured for selected words containing /p, b, g, k/. Univariate analyses of variance indicated that phonatory-articulatory timing, as measured with voice onset time, was different among the three groups for /g/, with the untrained-untalented singers displaying longer voice onset time than the trained singers. No other significant differences were observed across the other phonemes. Despite a significant difference observed, relatively small effect sizes and statistical power make it difficult to draw any conclusions regarding the usefulness of voice onset time as an indicator of singing talent.
