The DRD4 VNTR polymorphism moderates craving after alcohol consumption.

Recent research has suggested that alterations in mesolimbic dopamine neurotransmission are central to the development and expression of craving for alcohol. Because the D4 dopamine receptor gene, variable numbers of tandem repeats (DRD4 VNTR) polymorphism putatively expresses functional differences in dopamine receptors, the present study tested whether this polymorphism influences the effects of a priming dose of alcohol on craving. Participants consumed 3 alcoholic drinks or 3 control drinks and completed measures of craving after each drink. Participants who were homozygous or heterozygous for the 7 (or longer) repeat allele were classified as DRD4 L, whereas the other participants were classified as DRD4 S. Results suggested that DRD4 L participants demonstrated significantly higher craving after consumption of alcohol as compared with the control beverage.     

Who I am and how I think: The impact of self‐construal on the roles of internal and external reference prices in price evaluations

Drawing from self-construal studies on cognitive styles as well as reference price literature, this research investigates the impact of independent versus interdependent self-construal on consumers' use of internal reference prices (IRPs) and external reference prices (ERPs) during price evaluations. Three experiments reveal that IRPs have a larger impact on price evaluations for participants who are primed with an independent (vs. interdependent) self-construal, whereas ERPs have a larger impact for participants who are primed with an interdependent (vs. independent) self-construal. The differential impact of self-construal on the use of IRPs and ERPs seems to be mediated by a generalized, perceived sense of connectedness/separateness. Implications on reference price research, self-construal and cognitive styles are discussed.     

When are moods most likely to influence consumers' product preferences? The role of mood focus and perceived relevance of moods

This program of research examined the hypothesis that moods are most likely to be used as a source of information in making evaluations and choices when consumers both focus on their moods (i.e., acknowledge and pay attention to their feelings) and perceive that moods are a relevant source of information for forming judgments. Support for this prediction was obtained when the relevance of moods was examined by manipulating relevance instructions, varying advertising cues, and manipulating product type. Further, the boundary conditions under which the combination of mood focus and perceived relevance is most influential on product preferences are identified.     

Gender and developmental patterns of affect, belief, and behavior in simulated injury events

This study examined the hypothesis drawn from epidemiological data that beliefs and affective reactions of male second, fifth, and eighth graders, undergraduates, and adults in response to a series of four simulated bicycle collisions would show decreased expectation and avoidance of injury in comparison to females. This study also contrasted two additional hypotheses, one suggesting an invincibility belief in teenagers, producing a curvilinear age trend, with risky cognitions increasing from second grade, peaking at eighth grade, and then decreasing in adulthood. The other hypothesis suggested that with exposure, risky beliefs increased linearly, due to desensitization to cues of risk. As predicted, female participants did expect more fear and pain, and less exhilaration, and braked sooner after seeing the hazard than male participants. Linear rather than curvilinear age patterns emerged across films, revealing that the youngest participants anticipated more fear and less exhilaration than older participants. These results parallel developmental trends in which females and younger participants who anticipate more serious consequences are at lower risk for bicycle injury than are males, older children, and adolescents. Limitations of this analogue study and potential questions for both future research and the application of injury prevention techniques are explored.     

Psychophysical supervenience: Its epistemological foundation

My primary goal in this paper is to focus attention on a certain conception of internal access, on the Cartesian conception that a rational subject's capacity to determine sameness and difference in explicit propositional attitudes is independent of knowledge of the external world. This conception of introspection plays a crucial, if unacknowledged, role in numerous arguments and theoretical positions. In particular, it plays a large role in motivating psychological internalism. I argue in favor of rejecting this epistemology and the internalism it supports.     

Child victims: Searching for opportunities to break the cycle of violence

In 1986 I began research to address the relationship between early child abuse and neglect and later deliquent and violent criminal behavior using a prospective cohort design. The relationship is not inevitable, suggesting an opportunity for long-range violence prevention through appropriate early intervention. Here, I briefly describe how childhood victimization and violent criminal behavior are related and illustrate a number of promising strategies and opportunities to intervene. Finally, I offer five principles to guide interventions: (1) the earlier the intervention, the better; (2) don't neglect neglected children; (3) one size does not fit all; (4) surveillance—a double-edged sword; and (5) accessibility to resources. Rather than focusing on responses to child abuse or neglect in court proceedings that “treat” offenders, primary prevention efforts should target childhood victims to reduce their risk of becoming offenders in the future.     

Public Opinion and Political Philosophy: The Relation between Social-Scientific and Philosophical Analyses of Distributive Justice

This paper considers the relation between philosophical discussions of, and social-scientific research into popular beliefs about, distributive justice. The first part sets out the differences and tensions between the two perspectives, identifying considerations which tend to lead adherents of each discipline to regard the other as irrelevant to its concerns. The second discusses four reasons why social scientists might benefit from philosophy: problems in identifying inconsistency, the fact that non-justice considerations might underlie distributive judgments, the way in which different principles of justice can yield the same concrete distributive judgments, and the ambiguity of key terms. The third part distinguishes and evaluates three versions of the claim that normative theorising about justice can profit from empirical research into public opinion: that its findings are food for thought, that they amount to feasibility constraints, and that they are constitutive of normatively justified principles of justice. The view that popular opinion about justice has a strongly constitutive role to play in justifying principles of distributive justice stricto sensu is rejected, but it is argued that what the people think (and what they can reasonably be expected to come to think) on distributive matters can be an important factor for the political theorist to take into account, for reasons of legitimacy, or feasibility, or both.     

Tympanic thermometry: an index of hemispheric activity

This article describes the use of tympanic thermometry in investigations of hemispheric specialization. Subjects were asked to perform tasks known to be performed preferentially by the right or left hemisphere while fluctuations in tympanic temperature (reflecting changes in hemispheric metabolic activity) were recorded from thermal sensors placed in their outer ear canals. The analyses show that subjects who evince relatively higher elevations in metabolic activity (as measured through tympanic thermometry) in the hemisphere specialized for the task obtain better performance scores than those who show a reversed bias.     

Assessment of sexually abused children with anatomically detailed dolls: A critical review

The use of anatomically detailed (AD) dolls is widespread, especially with young children who have been, or may have been, sexually abused. A number of empirical studies have compared the responses of sexually abused and non-abused children to AD dolls. Additional research has assessed AD doll play among non-abused children only. Methodological limitations notwithstanding, virtually all empirical data support the use of AD dolls for data gathering in cases of sexual abuse.     

Internal-external locus of control and performance on a vigilance task.

Previous studies have demonstrated there are large individual differences in subjects' ability to perform on vigilance or watch-keeping tasks. This study used Rotter's Internal-External (I-E) Locus of Control Scale to resolve some of the variance attributed to individual differences and tested the hypothesis that the internally controlled person is a better monitor on a vigilance task than an externally controlled person. There were 64 subjects who performed a visual watch-keeping task for a 1-hr. period. The results indicated that the external subjects made significantly more incorrect responses and missed significantly more signals during the entire task. The internal-external dimension was effective in differentiating performance on a vigilance task.
