Overlooking the Obvious: Incentives to Lie

Over the years, people have searched for deception cues in the liar's behavior. However, the sender's incentives to lie might be more revealing than behavior. In Experiment 1, an incentive was developed that was predictive of lying. Judges with access to incentive information in addition to behavior achieved almost perfect lie/truth detection. This was not a result of the speakers' behavior being transparent (Experiment 2) but because incentive information was useful to separate lies from truths (Experiments 2 and 3). Experiment 3 revealed that people may forego perfectly diagnostic contextual cues to base their judgments on illusory behavioral cues.     

Naltrexone's effects on reactivity to alcohol cues among alcoholic men

The mechanisms of naltrexone's effects on urges to drink during abstinence are unclear. Naltrexone may suppress either urges to drink specifically or appetitive responses in general. The effects of naltrexone on cue reactivity to alcoholic and sweet nonalcoholic beverages were investigated. Alcohol-dependent men (N = 53) in treatment received naltrexone (50 mg) or placebo. Four hours later, they received baseline assessment, exposure to fruit juice, and exposure to their usual alcoholic beverage in 3-min trials. Naltrexone reduced urge to drink and self-reported attention to the alcohol cues, not at the initial exposure but after repeated exposures to alcohol cues. Naltrexone reduced negative affect across baseline and alcohol trials. No effects of naltrexone on responses to the nonalcoholic appetitive beverage cues were found, suggesting that general appetite suppression does not mediate the effects of naltrexone on urges.     

Alcohol,Fear, and Woman Abuse

Although there is ample evidence that alcoholusage is associated with greater frequency, incidenceand severity of spouse battering, there is alsoconsiderable evidence which does not support a direct linkage. This research investigates aheretofore neglected area, the role of substance use ininducing fear in victims. As part of a larger study ofthe police response to battering, 419 female victims of male offenders participated in intensiveinterviews; the sample consisted of 69.9% Black and28.9% White women. All the women had been victims of atleast one occurrence of misdemeanor-level abuse, and many were in chronically abusive relationships.The women participating in this study were moderatelyeducated and relatively young, with a mean age of 30years old. Relationship status was bimodal with roughly equal numbers of married and cohabitingcouples; there were relatively few who were divorced orseparated from their assailants, or were ex-cohabitants.The male partners of women represented in this sample were extremely heavy drinkerscompared to a national sample. The quantity andfrequency of alcohol use was less predictive ofthreatening or physically battering behavior than wasmale drunkenness. Frequent drunkenness was highly correlated withboth threats and with battering. Similarly, victims'fear of their partners was much more strongly associatedwith how frequently they were drunk than with drinking itself.     

Is sexual-aggressive vocal communication related to asymmetric mechanisms in the brain?

In Mongolian gerbil males, a reliable asymmetric relationship has been discovered between a stereotyped ultrasonic vocalizattion and the volume of a discrete nucleus within the preoptic-anterior hypothalamic area, the sexually dimorphic area, pars compacta (SDApc). The steroid-sensitive ultrasonic, emitted at high levels during courtship interactions, is associated with the absence of aggressive encounters and appears to be necessary for the formation and maintenance of pair-bonds with females. Interactions between unfamilliar, non-pair-bonded adult male and estrous female gerbils result in male aggression, reduction of male ultrasonic calling, and disruption of normal female dartmale follow sociosexual sequences. Castration further reduces ultrasonic calling, inhibits normal sociosexual sequences, and increses aggression in interaction between unfamiliar compared to pair-bonded individuals. Bothg brain structure and lateralization of vocal function in males depend on the action of sex steroids during sexual differentiation and in adulthood. Thus, the gerbil provides a new model to study steroid-dependent lateralization of brain mechanisms of vocal behavior mediating aggressive-sexual relationships. © 1994 Wiley-Liss, Inc.     

Sources of Perceived Organizational Support: Goal Setting and Feedback1

In this paper we examine goal setting and feedback as possible sources of perceived organizational support (Eisenberger, Huntington, Hutchison, & Sowa, 1986). Surveys were administered to 337 employees from 3 different organizations in the southern California area. Two path models were examined: one that allowed goal setting and feedback to have direct effects on perceived support and organizational commitment, and one that only allowed goal setting and feedback to have direct effects on perceived support. Results show that goal setting and feedback do not have direct effects on organizational commitment but, rather, affect commitment indirectly by way of their effects on employee perceptions of support from the organization.     

Gender Bias in Medical Implant Design and Use: A Type of Moral Aggregation Problem?

In this article, I describe how gender bias can affect the design, testing, clinical trials, regulatory approval, and clinical use of implantable devices. I argue that bad outcomes experienced by women patients are a cumulative consequence of small biases and inattention at various points of the design, testing, and regulatory process. However, specific instances of inattention and bias can be difficult to identify, and risks are difficult to predict. This means that even if systematic gender bias in implant design is an ethical issue, it is one with no clearly blameworthy player. From a practical perspective, there is no single obvious point at which to intervene. Philosophers working in other areas have explored structurally similar moral problems—sometimes referred to as “moral aggregation problems”—such as the type of environmental harm caused by small actions of many players. I describe key features of these type of problems and strategies to address them. I then draw on these to suggest an approach to gender bias in medical implant design and use.     

Getting rid of the bad ones: The relationship between group identification, deviant derogation, and identity maintenance

Two studies investigated the impact of the presentation of an undesirable group member on group stereotype judgments among participants with varying degrees of ingroup identification. In Study 1 (N = 67), identification was associated with stereotype change following presentation of an undesirable, but not a desirable, ingroup member. This relationship was mediated by evaluations of the undesirable ingroup member: the stronger the identification, the more negative the evaluation, and the greater the shift towards a more positive ingroup stereotype. In Study 2 (N = 180), identification was positively associated with ingroup stereotype ratings following presentation of an undesirable ingroup member but was negatively associated with outgroup ratings following presentation of an undesirable outgroup member. As in Study 1, the association between ingroup identification and ingroup stereotype ratings was mediated by evaluations of the undesirable ingroup member. Results are discussed in relation to the black sheep effect and identity maintenance strategies.
