High school drinking and its consequences

The present study surveyed 930 high school students regarding self-reported alcohol use, their perceptions of parents and peers, and the negative consequences of drinking. Two-fifths of males and one-fifth of females reported frequent problem (binge) drinking. Problem drinkers reported more negative consequences associated with drinking. In addition, problem drinkers reported greater susceptibility to peer pressure, perceived their peers as drinking more, and reported less parental monitoring and more use of alcohol by parents. The results demonstrate the importance of both parent and peer variables in adolescent substance use and highlight the negative consequences of drinking reported by high school students.     

Effects of food priming on instrumental acquisition and performance

Four experiments investigated the effects of a priming food reinforcement, given 0 or 75 sec pretrial, on runway performance of rats. The studies differed in the use of between-versus-within-subject designs, and by using food or water as the goal reinforcer. In Experiment 1, using food as the goal reward, subjects primed with food 0 sec pretrial conditioned slower than subjects primed 75 sec pretrial. In Experiment 2, using water as the goal reward, subjects primed with food 0 sec pretrial conditioned faster. These differences were evident on both prefed trials and on nonprefed test trials. Experiments 3 and 4 showed an opposite pattern of results when within-subject comparisons of 0- and 75-sec pretrial intervals were used: Food priming immediately pretrial facilitated food-rewarded running but inhibited water-rewarded running. The results suggest prefeeding has differential effects on acquisition and performance of instrumental behavior, and also depending upon the similarity of the priming and goal reinforcers.     

GPS: A Randomized Controlled Trial of Sexual Health Counseling for Gay and Bisexual Men Living With HIV

Gay, bisexual, and other men who have sex with men (GBM) continue to have high rates of HIV and sexually transmitted infections, including syphilis. GBM have therefore been identified by public health agencies as a high-priority population to reach with prevention initiatives. Despite the importance of mental health in preventing HIV and related infections, there is a shortage of credentialed mental health professionals to deliver behavioral Counseling interventions. The current study evaluated the efficacy of GPS, a community-based and peer-delivered sexual health promotion motivational interviewing–based intervention for HIV-positive GBM who engaged in condomless anal sex (CAS) in the past 2 months. GPS prevention counseling demonstrated a 43% relative reduction at 3-month follow-up in CAS with serodiscordant partners and significant reductions in sexual compulsivity. The study demonstrated that community-based counselors can administer an efficacious motivational interviewing program, and suggests a continued benefit of counseling methods to promote the sexual health of higher risk populations.     

Children's working-memory processes: a response-timing analysis

Recall response durations were used to clarify processing in working-memory tasks. Experiment 1 examined children's performance in reading span, a task in which sentences were processed and the final word of each sentence was retained for subsequent recall. Experiment 2 examined the development of listening-, counting-, and digit-span task performance. Responses were much longer in the reading-and listening-span tasks than in the other span tasks, suggesting that participants in sentence-based span tasks take time to retrieve the semantic or linguistic structure as cues to recall of the sentence-final words. Response durations in working-memory tasks helped to predict academic skill and achievement, largely separate from the contributions of the memory spans themselves. Response durations thus are important in the interpretation of span task performance.     

Transfer of value from fit

People experience regulatory fit when they pursue a goal in a manner that sustains their regulatory orientation (E. T. Higgins, 2000). Five studies tested whether the value experienced from regulatory fit can transfer to a subsequent evaluation of an object. In Studies 1 and 2, participants gave the same coffee mug a higher price if they had chosen it with a strategy that fit their orientation (eager strategy/promotion; vigilant strategy/prevention) than a strategy that did not fit. Studies 3-5 investigated possible mechanisms underlying this effect. Value transfer was independent of positive mood, perceived effectiveness (instrumentality), and perceived efficiency (ease), and occurred for an object that w as independent of the fit process itself. The findings supported a value confusion account of transfer.     

Hutchesonian Inspired Agent‐Based Virtue Ethics

Francis Hutcheson's moral sense theory is the inspiration for both act utilitarianism and a contemporary virtue ethics approach that Michael Slote calls agent‐based virtue ethics. In this essay, I look at other possibilities for ethical theory that spring from Hutcheson's writings and conclude that the landscape of sentimentalist inspired ethics is richer than many realize. I begin this article with a short explanation of Hutcheson's moral sense theory. I explain that Hutcheson proposes and embraces three distinct criteria of moral evaluation, one of which is concerned with the evaluation of motives and two of which are concerned with the evaluation of acts. Act utilitarianism adopts one of the criteria of act evaluation, and Slote's agent‐based virtue ethics adopts the remaining criterion of act evaluation and the criterion of motive evaluation. Then, after pointing out what I believe are shortcomings of Slote's agent‐based virtue ethics, I propose two Hutchesonian inspired theories, each of which is a compromise between act utilitarianism and agent‐based virtue ethics. The first, which I call hypothetical agent‐based virtue ethics, adopts two of Hutcheson's three criteria and is similar structurally to a virtue ethics theory articulated by Rosalind Hursthouse and Linda Zabzebski. The second, which, for lack of a better name, I call Hutchesonian hybridism, adopts all three of Hutcheson's criteria and is a hybrid combination of Slote's actualist agent‐based virtue ethics and hypothetical agent‐based virtue ethics. I argue that both hypothetical agent‐based virtue ethics and Hutchesonian hybridism overcome the shortcomings (pointed out earlier in this essay) of Slote's actualist agent‐based virtue ethics, and that both of these theories are, therefore, worthy of further consideration.     

THE SIMILARITY OF BRAIN ACTIVITY ASSOCIATED WITH TRUE AND FALSE RECOGNITION MEMORY DEPENDS ON TEST FORMAT

Abstract— Event-related potentials (ERPs) were compared for correct recognitions of previously presented words and false recognitions of associatively related, nonpresented words (lures). When the test items were presented blocked by test type (old, new, lure), waveforms for old and lure items were different, especially at frontal and left parietal electrode sites, consistent with previous positron emission tomography (PET) data (Schacter, Reiman, et. al., 1996). When the test format randomly intermixed the types of items, waveforms for old and lure items were more similar. We suggest that test format affects the type of processing subjects engage in, consistent with expectations from the source-monitoring framework (Johnson, Hashtroudi, & Lindsay, 1993). These results also indicate that brain activity as assessed by neuroimaging designs requiring blocked presentation of trials (e g, PET) do not necessarily reflect the brain activity that occurs in cognitive-behavioral paradigms, in which types of test trials are typically intermixed.     

Beyond Stewardship? Dietrich Bonhoeffer on Nature

This article questions whether the model of stewardship is helpful in considering Christian responsibility towards non‐human nature and proposes a different way of treating the issue of care of the environment. In an extended engagement with the theology of Dietrich Bonhoeffer, the article argues that human relations to non‐human nature are best understood by seeing humanity as historical, political and natural. In theological formulation, humanity must be understood asimago dei, imago civitatis andimago mundi. Therefore the place of humanity cannot properly be understood without reference to both God and nature. Humanity, nature and God thereby constitute a ‘common realm’. A new test of Christian responsibility towards non‐human nature is introduced: of primary interest is how historical, political and natural humanity acts in ways which either reveal or obscure the ‘common realm of God, nature and humanity’. At this point, theological self‐understanding moves beyond the model of stewardship.     

Relevance and digressions in argumentative discussion: A pragmatic approach

Digressions in argumentative discussion are a kind of failure of relevance. Examination of what actual cases look like reveals several properties of argumentative relevance: (1) The informational relevance of propositions to the truth value of a conclusion should be distinguished from the pragmatic relevance of argumentative acts to the task of resolving a disagreement. (2) Pragmatic irrelevance is a collaborative phenomenon. It does not just short-circuit reasoning; it encourages a failure to take up the demands of an argumentative task. (3) Pragmatic irrelevance can occur not simply by the absence of a connection between what is said and some standpoint in dispute, but also by the presence of a connection between what is said and a competing use of the information. (4) Pragmatic relevance must be accomplished through communicative action.     

Incorporating inferences in narrative representations: A study of how and why

Four experiments examined the conceptual organization of narrative passages and the extent to which these representations were explanatory in a variety of experimental tasks. The conceptual representation of a passage consisted of a graph of labeled nodes and labeled, directed arcs which were adopted from the Conceptual Dependency Theory. These representations included both explicitly stated information and inferences which had been empirically extracted by a question-answering procedure. Symbolic procedures for answering how- and why-questions were also delineated. The conceptual representations and the symbolic procedures that operate on these representations together accounted for 91% of the answers generated from question-answering protocols in Experiment 1, and also the rated quality of specific answers to specific questions in Experiment 2. Experiments 3 and 4 supported the hypothesis that structural properties of the representations can predict recall of explicitly stated nodes and verification ratings of inference nodes. The results provide encouraging support for the proposed graphic representations and also for the use of question-answering protocols in uncovering prose inferences.
