Sex education sources and attitudes toward sexual precautions across a decade

75 college students responded to Moore and Barling's AIDS questionnaire. Coopersmith's Self-esteem Inventory, and a background survey regarding sex education and sexual and religious activity. The most commonly reported sources of sex education were peers, parents, and high school courses, respectively. Ratings of the most important of 10 potential sources of sex education included peers, high school courses, and religious institutions, respectively. None of these were significantly correlated with future condom use. Virgins reported more open communication with parents about sex. Sexual experience was positively related to more confusion about sexual precautions but negatively related to foreclosed attitudes toward such precautions. Some types of religious involvement (church attendance and campus religious organization membership) were related to foreclosed attitudes. Data in attitudinal and sex education were compared with data collected in 1991. Although students more frequently reported having received sex education in 2000, their attitudes toward utilizing sexual precautions have become somewhat more diffused.     

Strategy-dependent changes in memory: Effects on behavior and brain activity

In the present study, an implicit strategy manipulation was used to explore the contribution of memory strategy to brain activation and behavioral performance. Participants were biased to use either a short-term (maintenance-focused) or long-term (retrieval-focused) memory strategy within a single memory task through manipulation of task context. In comparing directly matched trials across the different task contexts, we observed clear changes in both behavioral performance and brain activity across a network of regions located primarily within lateral and medial frontal cortex. These effects of the memory strategy manipulation suggest that when a retrieval-focused strategy is induced, mnemonic processes are preferentially engaged during the encoding period. In contrast, when a maintenance-focused strategy is induced, mnemonic processes are preferentially engaged during the delay and response periods. Taken together, the results imply that covert cognitive strategies play an important role in modulating brain activation and behavior during memory tasks.     

Relaxing decision criteria does not improve recognition memory in amnesic patients

An important question about the organization of memory is whether information available in non-declarative memory can contribute to performance on tasks of declarative memory. Dorfman, Kihlstrom, Cork, and Misiaszek (1995) described a circumstance in which the phenomenon of priming might benefit recognition memory performance. They reported that patients receiving electroconvulsive therapy improved their recognition performance when they were encouraged to relax their criteria for endorsing test items as familiar. It was suggested that priming improved recognition by making information available about the familiarity of test items. In three experiments, we sought unsuccessfully to reproduce this phenomenon in amnesic patients. In Experiment 3, we reproduced the methods and procedure used by Dorfman et al. but still found no evidence for improved recognition memory following the manipulation of decision criteria. Although negative findings have their own limitations, our findings suggest that the phenomenon reported by Dorfman et al. does not generalize well. Our results agree with several recent findings that suggest that priming is independent of recognition memory and does not contribute to recognition memory scores.     

Human Eyeblink Classical Conditioning: Effects of Manipulating Awareness of the Stimulus Contingencies

Obsessive-compulsive disorder (OCD) is an intrusive and debilitating condition in which the individual experiences uncontrollable thoughts, compulsions, and urges. Successful treatments for OCD are based on Mowrer's theory of fear and avoidance behavior, which predicts that OCD subjects should show accelerated associative conditioning. This prediction was tested in two experiments that com-pared the classical eyeblink conditioning of OCD-like and control college students. OCD and control subjects learned normally and similarly when the conditioning procedure was accompanied by an active visual search background task (Experiment 1). However, when the background task was changed so that subjects passively viewed neutral pictures, OCD subjects conditioned significantly faster than control subjects (Experiment 2). Overall, the performance of all subjects in Experiment 1 was superior to the performance of subjects in Experiemnt 2.

Cognitive activity and physiological arousal: Processes that mediate mood-congruent memory

This research proposes that the cognitive activity associated with the experience of an emotional state mediates the occurrence of mood-congruent processing. Two experiments examined the role of cognitive activity in selective processing of words in a mood congruence paradigm. Four induction procedures were used: a depressed-mood induction, a schema induction organized around the theme of writing a paper, an arousal induction, and a control neutral-mood induction. The memory task consisted of recalling a word list composed of negatively associated and thematically organized words. Selective processing was demonstrated in conjunction with the depressed-mood and organizational-schema induction procedures. In contrast, the arousal and neutral induction procedures did not produce selective processing of words from the list. The findings support the thesis that cognitive activity mediates the selective processing typical of mood congruence as distinct from arousal processes per se. The findings are discussed with respect to the resource allocation model and semantic network theory.     

Two effects of repetition: Support for a dual-process model of know judgments and exclusion errors

In three experiments, aremember/know recognition test (Experiments 1–2) and an exclusion test (Experiments 2–3) were used to examine effects of repeated study presentations. An effect of study repetition was obtained for remember but not know judgments, similar to results reported by Gardiner, Kaminska, Dixon, and Java (1996). Experiment 2 demonstrated the similarity between know responses and exclusion errors; neither was affected by repeated study presentations. In Experiment 3, a response deadline procedure was used to show that exclusion errors are the product of two opposing processes—recollection and familiarity—both of which are influenced by repetition. The interpretation of exclusion errors and know responses is shown to require a dual-process model that includes an assumption about the relationship between processes.     

Contrasting Cortical Activity Associated with Category Memory and Recognition Memory

We collected functional neuroimaging data while volunteers performed similar categorization and recognition memory tasks. In the categorization task, volunteers first studied a series of 40 dot patterns that were distortions of a nonstudied prototype dot pattern. After a delay, while fMRI data were collected, they categorized 72 novel dot patterns according to whether or not they belonged to the previously studied category. In the recognition task, volunteers first studied five dot patterns eight times each. After a delay, while fMRI data were collected, they judged whether each of 72 dot patterns had been studied earlier. We found strikingly different patterns of brain activity in visual processing areas for the two tasks. During the categorization task, the familiar stimuli were associated with decreased activity in posterior occipital cortex, whereas during the recognition task, the familiar stimuli were associated with increased activity in this area. The findings indicate that these two types of memory have contrasting effects on early visual processing and reinforce the view that declarative and nondeclarative memory operate independently.     

Predicting the Outcomes of Disputes: Consequences for Disputant Reactions to Procedures and Outcomes1

Third parties in dispute settings often make predictions to disputants regarding the likely outcome of their dispute at arbitration. However, virtually no research has examined the impact of predictions on disputant satisfaction with dispute resolution procedures and outcomes. One explanation for the lack of attention to this variable may be that current theorizing regarding dispute resolution procedures is too narrowly stated to incorporate this procedural variation. Theories about predictability from nondispute settings are used to generate hypotheses regarding the consequences of such outcome prediction. In a laboratory setting, disputants prepared arguments in anticipation of an arbitration hearing. Prior to the arbitrator's decision, the experimenter read the disputants' arguments and made a prediction regarding the arbitrator's decision. Their arguments were then presented to an arbitrator who imposed a binding decision. Dependent measures include the disputants' anxiety while awaiting the arbitrator's decision, and their postdecision satisfaction with dispute resolution procedures and outcomes. Internal analyses support the hypothesis that outcome prediction has benefits for disputants' predecision coping, ratings of procedural fairness, and satisfaction judgments. Also, as hypothesized, correct predictions produced greater postdecision satisfaction with outcomes and decision-makers than did incorrect predictions.
