Gender and Sexual Risk

Two hypotheses are evaluated in thisinvestigation of gender differences in the attitudinaland behavioral correlates of sexual risk. Thedifference in magnitude hypothesispredicts that the same factors are implicated for women and men butdifferences occur in the strength of correlates.Alternatively, women may engage in sexual risk fordifferent reasons than do men, leading to adifference in pattern hypothesis. We compared these possibilitieswith a sample of 576 primarily White, middle-class,never-married college students, most of whom werebetween 17 and 25 years of age. Analyses of loveattitudes, risk perception, sensation seeking, and riskbehaviors in other domains in relation to sexual riskbehavior showed some gender similarities as well asdifferences. Findings were more consistent with the difference in pattern hypothesis than with thedifference in magnitude hypothesis.     

Assessment of the school readiness section of the early detection inventory: Preschool prediction across situational factors

The efficiency of (a) a school readiness test, (b) mental age, and (c) specific sensory and perceptual skills was tested as predictors of word recognition at the end of the first school year. Five hundred and eigth children in four schools with three significantly different socioeconomic backgrounds were tested in kindergarten. Two schools were in the same middle-class area: one was a traditional classroom school, the other was open space in structure. When the variables were examined by means of stepwise regression analysis and partial correlations, the school readiness test appeared as the most efficient predictor in each of the four schools, as well as in the total group. Mental age and auditory skills ranked either second or third in importance depending on the school situation.     

Spirituality and Health Outcomes in the Elderly

The purpose of this mail survey was to examine the relationship of attitudinal and behavioral measures of spirituality to physical and mental health outcomes in a sample of elderly community residents. Frequency of prayer, importance of faith, and reliance on religion for their coping were compared for their association with eight categories of physical and mental health. All three measures, prayer, faith and religious coping, correlated strongly with positive mental health, but not with the other seven physical health categories. Multiple regression analyses indicated importance of one's faith had the strongest association with positive mental health, even after controlling for the effect of other significant variables, age and education. The behavioral measure of prayer was a component of importance of faith to mental health, with no independent impact. This study highlights attitudes rather than practices, as the stronger spiritual variables related to mental health in the elderly.     

Oppositions and Paradoxes in Mathematics and Philosophy

In this paper a number of oppositions which have haunted mathematics and philosophy are described and analyzed. These include the Continuous and the Discrete, the One and the Many, the Finite and the Infinite, the Whole and the Part, and the Constant and the Variable.     

The theory of planned behavior and healthy eating.

Application of the theory of planned behavior (TPB) to healthy eating in 144 health promotion clinic attendees is reported. Respondents completed self-report TPB measures after the clinic (Time 1) and 6 months later (Time 2) with a measure of perceived past behavior. Intention stability was assessed on Time 1-2 differences. Six years later (Time 3), respondents completed measures of healthy eating intentions and behavior. Intentions were predicted by attitudes, perceived behavioral control, and perceived past behavior (cross-sectionally). Healthy eating behavior (Time 3) was predicted from intentions (Time 2). As intention stability increased, intentions and perceived past behavior became stronger and weaker predictors of behavior, respectively. Implications for understanding health cognitions in long-term performance of health behavior are discussed.     

Active learning: effects of core training design elements on self-regulatory processes, learning, and adaptability

This article describes a comprehensive examination of the cognitive, motivational, and emotional processes underlying active learning approaches; their effects on learning and transfer; and the core training design elements (exploration, training frame, emotion control) and individual differences (cognitive ability, trait goal orientation, trait anxiety) that shape these processes. Participants (N = 350) were trained to operate a complex, computer-based simulation. Exploratory learning and error-encouragement framing had a positive effect on adaptive transfer performance and interacted with cognitive ability and dispositional goal orientation to influence trainees' metacognition and state goal orientation. Trainees who received the emotion-control strategy had lower levels of state anxiety. Implications for development of an integrated theory of active learning, learner-centered design, and research extensions are discussed.     

If-then contingencies and the differential effects of the availability of an attractive alternative on relationship maintenance for men and women

In 7 experiments, the causal effects of the availability of an attractive alternative (AA) relationship partner on current relationship thoughts and intentions were tested using confederates, mental simulations, and virtual reality. Men behaved consistent with traditional relationship-commitment theories, showing decreased willingness to tolerate their partner's transgressions after the availability of an AA was made salient. However, consistent with a motivated cognition approach to commitment and work on relational self-construals, women increased their tolerance when presented with the relationship threat of an alternative. Word-fragment and lexical decision data suggested that AAs may activate threat for women, and their ability to dampen threat accessibility is associated with prorelationship responses. Finally, this "if relationship is threatened, then defend the relationship" contingency was induced in men with an implementation intention induction.     

Reference dependence in iterative choices

Valuation of goods often proceeds from a series of hypothetical pairwise choices. We examine reference dependence on the outcome of such evaluations in a large-scale study in which respondents make a series of choices between areas that differ on cost of living and the quality of lakes and rivers. We uncover three substantial reference effects. First, we find that respondents’ choices are altered by being told the national value of water quality. For these people, consistent with prospect theory, changes in water quality below the 65% referenced national standard are treated as losses and given more weight while identical changes above 65% are treated as gains and given less weight. Second, we find that the sequence of iterative choices matters in a surprising way. The iterations proceed by encouraging switching either by degrading the chosen alternative or improving the item chosen. We show that improving the item not chosen produces the greatest switching, a result consistent with prospect theory, but only if the item changed in the iteration becomes the reference alternative. Finally, we find a strong starting reference effect. That is, we show that the trade-off in the first choice reflected in the change in cost of living divided by the change in water quality has a substantial impact on the final valuation. We assess the relative impact of these three reference effects and suggest ways of dealing with them for valuation of non-market goods.     

Double dissociation of pharmacologically induced deficits in visual recognition and visual discrimination learning

Monkeys trained in either one-trial recognition at 8- to 10-min delays or multi-trial discrimination habits with 24-h intertrial intervals received systemic cholinergic and dopaminergic antagonists, scopolamine and haloperidol, respectively, in separate sessions. Recognition memory was impaired markedly by scopolamine but not at all by haloperidol, whereas habit formation was impaired markedly by haloperidol but only minimally by scopolamine. These differential drug effects point to differences in synaptic modification induced by the two neuromodulators that parallel the contrasting properties of the two types of learning, namely, fast acquisition but weak retention of memories versus slow acquisition but durable retention of habits.
