Reducing HIV risk-associated sexual behavior among african american adolescents: Testing the generality of intervention effects

This randomized controlled trial tested the effects of a theory-based culture-sensitive HIV risk-reduction intervention among 496 inner-city African American adolescents (mean age = 13 years) and examined the generality of its effects as a function of the facilitator's race and gender and the gender composition of the intervention group. Adolescents who received the HIV risk-reduction intervention expressed more favorable behavioral beliefs about condoms, greater self-efficacy, and stronger condom-use intentions postintervention than did those who received a control intervention on other health issues. Six-month follow-up data collected on 93% of the adolescents revealed that those who received the HIV risk-reduction intervention reported less HIV risk-associated sexual behavior, including unprotected coitus, than did their counterparts in the control condition. Self-reported sexual behavior and changes in self-reported behavior were unrelated to scores on a standard measure of social desirability response bias. There was strong evidence for the generality of intervention effects. Moderator analyses testing eight specific interaction hypotheses and correlational analyses indicated that the effects of the HIV risk-reduction intervention did not vary as a function of the facilitator's race or gender, participant's gender, or the gender composition of the intervention group.

The changing face of police interrogation

This paper discusses some of the apparent changes in interrogations following the Police and Criminal Evidence Act 1984 and the introduction of tape recorders into police stations. These reforms are believed to have had several marked effects on interrogations. For example, the use of persuasive questioning is believed to have declined, as has the number of suspects making admissions. The evidence for these hypotheses is discussed. It is suggested that the apparent fall in confessions can be explained by methodological differences between studies and that the confession rate has in fact remained almost constant. Although there does appear to have been a change in the types of persuasive questioning employed during interrogations, it is difficult to establish whether or not the use of such questioning has declined. There is some evidence that persuasive questioning is now being carried out away from recording equipment.     

A picture is worth a thousandp values: On the irrelevance of hypothesis testing in the microcomputer age

Hypothesis testing, while by far the most common statistical technique for generating conclusions from data, is nonetheless not very informative. It emphasizes a banal and confusing question (“Is it true that some set of population means are not all identical to one another?”) whose answer is, in a mathematical sense, almost inevitably known (“No”). Hypothesis testing, as it is customarily implemented, ignores two issues that are generally much more interesting, important, and relevant: What is thepattern of population means over conditions, and what are the magnitudes of various variability measures (e.g., standard errors of the mean, estimates of population standard deviations)? The simple expedient of plotting relevant sample statistics with associated variability bars is a substantially better way of conveying the results of an experiment. In today’s microcomputer environment, there are many relatively cheap and easily available applications that allow one to do this. I make some brief, informal comments about some of these applications.     

Parameters affecting gap detection in the rat

The present research used a startle amplitude reduction paradigm to investigate the ability of the rat’s auditory system to track rapidly changing acoustic transients. Specifically examined was the ability of brief gaps in otherwise continuous noise to reduce the amplitude of a subsequently elicited acoustic startle reflex. The duration of the gap, time between gap offsetand startle elicitation (the interstimulus interval or ISI), and rise-fall characteristics of the gap were systematically varied. Consistent with previous research, gaps reliably reduced startle amplitude. Gaps 2 msec long were reliably detected, and a 50-msec ISI resulted in the greatest amplitude reduction. Gaps presented at short ISIs produced amplitude reduction that followed a different time course than did gaps presented at longer ISIs. These results may reflect differences in the length oftime available for the processing of the stimulus and may involve two different processes.     

Molding the Past: Biased Assimilation of Historical Information1

The present study examined whether individuals' current political worldviews would bias perceptions of historical information gathered over the course of their lifetime. Kent State University students from 1995 and 2000 reported their political ideologies (e.g., conservative, liberal) and responded to items assessing their culpability and global attributions about the shooting of demonstrators by the National Guard at Kent State in 1970. The 1995 data revealed consistent support for biased responding to culpability and global attribution items. The 2000 data replicated the political ideology differences of the 1995 data. However, by including knowledge of the incident as an independent variable, the 2000 data revealed that the political ideology bias was strongest among people reporting high knowledge about the event.     

Temporal self-appraisal and attributional focus

Temporal self-appraisal theory (Ross & Wilson, 2002; Wilson & Ross, 2001) states that individuals evaluate their past selves in a way that makes them feel good about their current self. The present studies tested the degree to which differences in attributional focus influence feelings of closeness to positive life events. In Study 1, participants recalled a recent positive life event before thinking about how either they personally or others were responsible for the event’s occurrence. As expected, participants felt temporally closer to the event when they had thought about internal attributions. In Study 2, after recalling a recent positive life event, participants recalled one (or six) reasons describing how they personally (or others) produced the event. The results revealed that participants used the content of retrieved attributions in deriving their temporal judgment. The implications of the findings for tenets of temporal self-appraisal theory are discussed.     

Multiple risk expert systems interventions: impact of simultaneous stage-matched expert system interventions for smoking, high-fat diet, and sun exposure in a population of parents.

Three stage-based expert system interventions for smoking, high-fat diet, and unsafe sun exposure were evaluated in a sample of 2,460 parents of teenagers. Eighty-four percent of the eligible parents were enrolled in a 2-arm randomized control trial, with the treatment group receiving individualized feedback reports for each of their relevant behaviors at 0, 6, and 12 months as well as a multiple behavior manual. At 24 months, the expert system outperformed the comparison condition across all 3 risk behaviors, resulting in 22% of the participants in action or maintenance for smoking (vs. 16% for the comparison condition), 34% for diet (vs. 26%), and 30% for sun exposure (vs. 22%). Proactive, home-based, and stage-matched expert systems can produce significant multiple behavior changes in at-risk populations where the majority of participants are not prepared to change.     

The ‘Constitutive Thought’ of Regret

In this paper I defend and develop Bernard Williams’ claim that the ‘constitutive thought’ of regret is ‘something like “how much better if it had been otherwise”’. An introductory section on cognitivist theories of emotion is followed by a detailed investigation of the concept of ‘agent-regret’ and of the ways in which the ‘constitutive thought’ might be articulated in different situations in which agents acknowledge casual responsibility for bringing about undesirable outcomes. Among problematic cases discussed are those in which agents have caused harm through no fault of their own, or have been constrained to choose the lesser of two evils or to act against their moral values. R. Jay Wallace’s ‘bourgeois predicament’ and related cases, in which we recognize that our present advantages have flowed from regrettable antecedents, further show that regret is often not a simple emotion, and it is argued that conflicted regrets are sometimes unavoidable. Finally, the paper looks at Descartes’ account of regret as a form of sadness engendered by the recollection of irrecoverable happy experiences, to which the ‘constitutive thought’ does not readily apply. It is suggested that what Descartes is discussing is a different genre of emotion for which ‘nostalgia’ might be a better name.     

Making a Party Leader Less of a Party Member: The Impact of Ambivalence on Assimilation and Contrast Effects in Political Party Attitudes

The present study tested the degree to which attitudes about a political party would be influenced by the context in which the party leader was rendered cognitively accessible. A sample of British undergraduates evaluated Prime Minister Tony Blair before expressing their opinion about the Labour party. In one condition, the two items were structured such that Blair was expected to be included in participants' representation of the party. In a second condition, the same items were structured such that Blair was expected to be excluded from participants' representation of the party. The results supported the hypothesis that manipulating the context in which Blair was made salient would produce different effects on a subsequent judgment of the Labour party, but only among politically ambivalent respondents.
