A Laboratory Demonstration of the Fraudulent Telemarketers’ 1‐in‐5 Prize Tactic1

Two laboratory experiments demonstrate the effectiveness of the 1‐in‐5 prize tactic for perpetrating telemarketing fraud crimes. Across these experiments, the 1‐in‐5 prize tactic (securing acquiescence to a request by misleading a person to believe that he or she has won a valuable prize) resulted in a 5‐fold increase in compliance, including 100% yielding in conditions most similar to those used by fraudulent telemarketers. Possible psychological mechanisms underlying the tactic (including phantom fixation) are discussed.     

Motivation to Control Prejudice as a Mediator of Identity and Affirmative Action Attitudes1

Affirmative action is a divisive issue in society today. Attitudes toward affirmative action vary both between and within ethnic and racial groups, with Whites exhibiting the majority of negative attitudes. Researchers have suggested a variety of psychological explanations for differences in attitudes toward affirmative action (e.g., racism, self‐interest, fairness). The current study investigates whether motivation to control prejudice acts as a mediator of ethnic/racial identity and Whites’ attitudes toward affirmative action. Support was found for the mediating role of motivation to control prejudice for several aspects of ethnic and racial identity and affirmative action attitudes. Limitations of the study are discussed, as are topics for future research.     

Alcohol seeking by rats: Action or habit?

In two experiments, we examined the relative susceptibility to outcome devaluation of lever pressing by rats for either a 10% ethanol solution or food pellets. The rats were trained to press different levers for these two reinforcers using a sucrose-substitution procedure. An aversion was then conditioned from either the ethanol solution or the food pellets by pairing consumption with illness induced by lithium chloride. When instrumental performance was subsequently tested in extinction, the rats pressed less on the pellet lever if the pellets, rather than the ethanol, had been devalued by aversion conditioning. By contrast, performance on the ethanol lever was unaffected by whether the ethanol or pellets were devalued. Moreover, noncontingent presentations of the devalued reinforcer had no impact on test performance. The differential resistance to outcome devaluation suggests that, in contrast to food seeking, alcohol seeking is a stimulus-response habit rather than a goal-directed action mediated by a representation of the action-outcome contingency.     

Adult attachment and sexual behavior

The relations between adult attachment processes and sexuality were examined in a community sample of 792 young adults (327 men and 465 women) from the Niagara region of Canada. Participants completed questionnaires that included Simpson’s (1990) measure of adult attachment, self‐reported physical attractiveness, erotophilia, and a variety of sexual behavior measures (e.g., number of sexual partners, age of first sexual experience, frequency of sexual behaviors in the past year, whether an affair had occurred in the past year, and consistent condom usage). The sexuality measures were factor analyzed to extract common factors. The results were modest, but a number of significant relationships between sexuality and attachment were observed. For example, people scoring higher on a secure attachment index perceived themselves as more physically attractive, whereas people scoring higher on an anxious attachment index perceived themselves as less physically attractive, had an early first intercourse (and more lifetime partners), more infidelity, and took more sexual precautions (e.g., condom usage). The results were generally stronger in women, with most of the attachment/sexuality associations in the full sample being driven by the results in women. Implications for understanding sexual variability, including high‐risk sexual behavior, are discussed.     

The triangle of interpersonal models

This article develops a framework for social psychology, the triangle of interpersonal models (TIM). TIM is a 2-dimensional classification scheme for the impact of people on social-psychological phenomena. TIM classifies a social-psychological phenomenon by the number of people who contribute to the phenomenon and the number of distinct social-psychological functions that those people serve. TIM includes models for phenomena that involve 1 person, 2 people, 3 people, and p people. In those phenomena, people serve 1, 2, 3, or f distinct social-psychological functions. TIM decomposes complex phenomena into components that reflect different levels of interpersonal causation. It brings rigor to holistic conceptions of social psychology and offers a fresh perspective on the relationship between the individual and the group.     

Self-reported changes in subjective health and anthrax vaccination as reported by over 900 Persian Gulf War era veterans

A 1999 study of United Kingdom servicemembers by Unwin, et al. recently found significant relationships between anthrax and other vaccinations, reactions to those vaccines, and later health problems for male current or former active military Gulf War veterans. Likewise, in 2000 Steele and in 1998 Gilroy found possible adverse effects of vaccinations on Gulf War veterans. However, the role of such vaccinations remains controversial; more recent government reports continue to dispute the existence of any data that might reflect adversely on the role of vaccinations on the health of Gulf War veterans. To address this controversy, the current study assessed similar relationships for over 900 Reserve Component Gulf War Era veterans from Ohio and nearby states. Gulf War veterans were more likely to report poorer health than non-Gulf veterans. Female veterans were more likely to report mild or severe reactions to vaccines than male veterans. Those veterans who received anthrax vaccine reported more reactions to vaccines than those who did not receive anthrax vaccine. Declines in long-term subjective health were associated with receipt of anthrax vaccine by Gulf War veterans but not for those who did not deploy to the Gulf, although few of the latter received anthrax vaccine. Regardless of deployment status, veterans who reported more severe reactions to vaccines were more likely to report declines in subjective health. Female veterans reported poorer health during the Gulf War than did male veterans, but sex was not related to veterans' reports of subjective health at subsequent times. It is recommended that servicemembers who experience severe reactions to anthrax vaccine be medically reevaluated before receiving further anthrax vaccine and that careful follow-ups be conducted of those receiving the vaccine currently, in accordance with Nass's 1999 recommendations. We also recommend that safer alternatives to thimerosal (a mercury sodium salt, 50% mercury) be used to preserve all vaccines.     

On doing two things at once: IV. Necessary and sufficient conditions: Rejoinder to Lien, Proctor, and Ruthruff (2003)

Four publications have demonstrated perfect timesharing of 1 simultaneous decisions. In all of these, (a). subjects were motivated to respond as quickly as possible, and with 1 exception that involved unusually extensive practice (E. Hazeltine, D. Teague, & R. B. Ivry, 2002, Experiment 4), (b). at least 1 of the 2 tasks was characterized by ideomotor (IM) compatibility, meaning that each task stimulus incorporated a component of the sensory feedback from its required response. Conclusions justified by these reports are that (a). the use of speed-stress instructions is necessary for perfect timesharing of 2 simultaneous decision tasks: (b). when both tasks are IM compatible, perfect timesharing requires little or no practice: (c). extensive practice is needed to achieve perfect timesharing when only 1 of the 2 tasks is IM compatible: and (d). very large amounts of practice can yield perfect timesharing of 2 decision tasks when neither is IM compatible.     

A high-field functional MRI study of quadri-lingual subjects

We assessed six multilingual subjects by functional MRI using a Noun Verb Generation task in four different languages. We hypothesised that the degree of proficiency in each language would be related to the extent of functional activity measured in a region of interest analysis. Proficiency in each language was quantified using two neuropsychological tests. All four languages activated overlapping brain areas, corresponding to the major language regions. The number of activated voxels correlated with proficiency, so that the activated volume increased for languages in which a subject had poorer proficiency. Activation did not appear to be dependent on the age at which the language was learnt.     

The role of atypical antipsychotics in glucose/insulin dysregulation and the evolving role of the psychiatrist in a new era of drug treatment options

This article examines the issue of atypical antipsychotics, glucose/insulin, and other metabolic derangements (ie, metabolic syndrome), including a general introduction to the health concerns of our patients, a review of the literature, possible mechanisms of antipsychotic induced glucose dysregulation, monitoring approaches, and management and prevention of metabolic syndrome. Literature review leads to mechanism hypotheses and risk estimations, leading to guidelines for monitoring and treatment. The patient population suffers from a higher degree of baseline metabolic dysregulation resulting in cardiovascular disease through components of the metabolic syndrome, and this risk increases with administration of atypical antipsychotic medication at different rates, depending on both drug and patient risk factors. The growing knowledge of mechanisms behind drug induced glucose/insulin and other metabolic dysregulation, as well as advances in pharmacogenomics, will help refine drug selection and monitoring for adverse, life-threatening metabolic effects.
