Investing Even in Uneven Contests: Effects of Asymmetry on Investment in Contests

Many competitions, such as political campaigns, innovative endeavors, sports, or courting rituals, require investment of nonrefundable resources: One contestant wins the prize for the invested amount, whereas all others lose their investments without receiving compensation. Frequently, contests are asymmetric, because of differing resources or prize valuations. Does asymmetry discourage the weaker contestants from investing? Do stronger contestants take this into account and also invest less? Or does the desire to win abolish these differences? Two experiments explored the effects of asymmetry between the contestants—arising from their resources or prizes—on nonrefundable investments. Subjects repeatedly competed in both symmetric and asymmetric contests, enabling within‐subject comparisons. We observed an effect of asymmetry only when it concerned resources: Subjects overall invested less when their resources were unequal, whereas inequality in the prizes did not influence investments. This pattern suggests that winning itself is motivating. The changes between consecutive investments can be explained by reactions to the previous outcome (win or loss): Across all contests, investment decreased following a win and increased following a loss.

A decision theoretic and prototype conceptualization of possible selves: implications for the prediction of risk behavior

The present study explores a new framework for conceptualizing possible selves for the prediction of behavior. The framework uses decision theory, attitude theory, and classic expectancy-value models. The focus is on using possible-self constructs that (a) correspond to behavioral alternatives, (b) focus on self dimensions directly tied to the behavioral criterion, and (c) use expectancy-value constructs to assess the core features of a given possible self-dimension. A study of 305 college students was undertaken to predict alcohol use from possible self constructs using the framework. Results affirmed the utility of the approach, showing that possible-self constructs predicted behavior over and above current self-image and constructs in the Theory of Planned Behavior. Possible-self constructs associated with negative attributes of both binge drinkers and nonbinge drinkers were predictive of behavior.     

An analysis of U.S. parachuting fatalities: 2000-2004

Between 2000 and 2004, 125 recreational parachuting fatalities were reported in the USA. Each was categorized using a previously reported taxonomy. While patterns of skydiving fatality were largely unchanged since the last such analysis of fatalities from 1993-1999, some variations were noted. As in previous analyses, most of the recent skydiving fatalities were the direct result of human error. Some examples of commonplace human error fatalities were turning low to the ground resulting in a hard landing, accidentally colliding with other skydivers resulting in entangled parachutes, and failure to deploy the reserve parachute correctly in the event of malfunctioning main parachute.     

From the Galleries to the Clinic: Applying Art Museum Lessons to Patient Care

Increasingly, medical educators integrate art-viewing into curricular interventions that teach clinical observation—often with local art museum educators. How can cross-disciplinary collaborators explicitly connect the skills learned in the art museum with those used at the bedside? One approach is for educators to align their pedagogical approach using similar teaching methods in the separate contexts of the galleries and the clinic. We describe two linked pedagogical exercises—Visual Thinking Strategies (VTS) in the museum galleries and observation at the bedside—from “Training the Eye: Improving the Art of Physical Diagnosis,” an elective museum-based course at Harvard Medical School. It is our opinion that while strategic interactions with the visual arts can improve skills, it is essential for students to apply them in a clinical context with faculty support—requiring educators across disciplines to learn from one another.     

Representing Versus Generalizing: Two Approaches to External Validity and Their Implications for the Study of Prejudice

Autobiographical memories are often suspect. For example, a surprisingly large number of people report having been abducted by extraterrestrials. We offer a prototype of the abduction experience and an assessment of the frequency of such reports. These accounts are hard to dismiss on the basis of mendacity or insanity, but there are ample reasons to doubt their literal accuracy. We offer a cognitive-motivational explanation for how spurious memories of unidentified flying object (UFO) abductions can be created and maintained. The motivational roots lie in the desire to escape from ordinary self-awareness, and this explanation is supported by parallels between UFO abduction accounts and masochistic fantasies. The cognitive bases involve the integration and elaboration of hallucinations, general knowledge, and contextual cues into full-blown accounts, usually with the aid of hypnosis. Due to the pitfalls of hypnosis, people develop a high degree of confidence in the veridicality of spurious UFO abduction memories.     

A Question of Foot Dominance

It is suggested that the popular definition of foot dominance (i.e., the limb preferred to execute a manipulative or mobilizing action while the other [nondominant] foot provides stabilizing support, e.g., kicking a ball) be reconsidered in light of understanding the functional characteristics of footedness and selected theoretical explanations. Relevance to future research designs and assessment methodology is discussed.     

Introduction

Abstract

This introduction to the two-paper panel, “Reconsidering questions regarding mutual analysis,” provides a context for the two papers that follow. The historical antecedents and contemporary climate for the issue of mutual analysis–and analytic mutuality more generally–are described. Each author's contribution is introduced, as are the essential questions common to the panel as a whole.     

Laboring and Hanging Out in the Embodied In‐Between

In this essay I describe how my involvement in the political struggles of an immigrant domestic workers' collective inspired me to hang out not only with the workers, but also with the writings of María Lugones and Hannah Arendt. The essay invites the reader to engage in a playful rereading of Arendt's notion of the worldlessness of laboring in the private realm by putting her into dialogue with Lugones's notion of the hangout that defies the public–private split Arendt adamantly insists on in all her writings. By following the complex physical, mental, and emotional itineraries of immigrant domestic workers to, from, and in‐between a number of places and spaces, I demonstrate how their stories blur the line between public and private, and therefore also between the unfreedom of the body and the presumed escape into the political public. I describe the women's experiences as the living promise of a world that allows for an embodied fluid movement between labor, work, and the freedom “inherent in action” (Arendt 193, 153).     

Negative Affect Shares Genetic and Environmental Influences with Symptoms of Childhood Internalizing and Externalizing Disorders

The co-occurrence of internalizing and externalizing disorders suggests that they may have common underlying vulnerability factors. Research has shown that negative affect is moderately positively correlated with both internalizing and externalizing disorders in children. The present study is the first to provide an examination of negative affect in relation to a wide spectrum of childhood internalizing and externalizing problems using a biometric model. This study extends prior findings of more narrowly focused associations by using a factor approach including multiple disorders. The sample for this study included families of 691 same-sex 7- to 13-year old twin pairs. A multifactorial independent pathway model was used to examine the genetic and environmental influences underlying the covariation of parent-reported negative affect, internalizing symptoms, and externalizing symptoms. Results of the current study suggest that negative affect shares genetic and environmental influences with both internalizing and externalizing disorders in childhood. These common influences may partially explain their comorbidity. Understanding that negative affect is at least one contributor to the covariation among these disorders may highlight avenues for early risk assessment, intervention, and perhaps prevention.
