Sleep Deprivation and Dating Aggression Perpetration in Female College Students: The Moderating Roles of Trait Aggression,Victimization by Partner,and Alcohol Use

Dating aggression, whether it is physical or psychological, is a major social concern. The background-situational model is highly predictive of dating aggression, but it lacks consideration of biopsychosocial processes. Sleep was investigated as one such process. A sample of 108 university undergraduate women completed objective (actigraphy) and subjective measures of sleep quality as well as self-reports of dating and trait aggression. Indicators of sleep deprivation were associated with greater frequency of dating aggression perpetration. Associations were especially strong when trait aggression and victimization by the partner were higher. Contrary to hypotheses, alcohol consumption did not significantly moderate the relation between sleep and women’s aggression perpetration. Less sleep was associated with women’s more frequent aggression toward their partners, perhaps because sleep deprivation causes difficulties with emotion regulation.     

Why does the effect of short-SOA exogenous cuing on simple RT depend on the number of display locations?

When the stimulus onset asynchrony (SOA) between the cue and target is short (i.e., less than 200 msec) and the number of display locations is small (e.g., only two), exogenous spatial cues produce a benefit in simple response time (RT). However, several recent experiments have found significant costs in these tasks when a large number of display locations is employed (e.g., eight), even at the very short SOAs that usually produce a benefit. The present study explored the dependence of exogenous cuing on the number of display locations and found evidence that both the overall validity of the cues and the specific validity of the cue on the previous trial have strong, additive effects. When a large number of display locations is used, both of these factorswork against a benefit of exogenous cuing on simple RT, reversing the typical finding into a cost. These two effects are suggested to occur within motor and perceptual processes, respectively.     

On the spatial metric of short-SOA costs of exogenous cuing

When the stimulus onset asynchrony (SOA) between the cue and the target is short, exogenous spatial cues usually produce a response time benefit. However, consistent with several recent studies, we have found that a short stimulus onset asynchrony is not sufficient. At least one more factor--the number of cue and target locations--also plays a role. Even more interesting, when 8 cue and target locations are used, the effect of an exogenous cue produces a cost on valid cue trials, and the spatial metric of this negative cuing effect depends on whether the cue remains visible at target onset.     

Virtue and Luck, Epistemic and Otherwise

This essay defends virtue reliabilism against a line of argument put forward by Duncan Pritchard. In the process, it discusses (1) the motivations for virtue reliabilism, (2) some analogies between epistemic virtue and moral virtue, and (3) the relation between virtue (epistemic and otherwise) and luck (epistemic and otherwise). It argues that considerations about virtue and luck suggest a solution to Gettier problems from the perspective of a virtue theory.     

Influence of Different Sitting Positions on Healthy Infants' Reaching Movements

The authors analyze the influence of different sitting positions (ring and flexion) on the reaching performance (spatiotemporal variables) of full-term infants 6 and 7 months old. In addition, they correlated level of trunk control, measured by the Segmental Assessment of Trunk Control, with performance during reaching. The different sitting positions only influenced the reaching movements of 6-month-old infants, who showed the best performance in the ring position. However, this influence was observed only for the trunk displacement, deceleration time, movement units, straightness index and mean velocity. In contrast, there was no influence of positions on 7-month-old infants’ reaching performance. Regarding the correlations, it was observed that infants with more level of trunk control showed a better performance when reaching, regardless of position and the age assessed.     

Emotional eating and Pavlovian learning: evidence for conditioned appetitive responding to negative emotional states

Appetitive learning has been demonstrated several times using neutral cues or contexts as a predictor of food intake and it has been shown that humans easily learn cued desires for foods. It has, however, never been studied whether internal cues are also capable of appetitive conditioning. In this study, we tested whether humans can learn cued eating desires to negative moods as conditioned stimuli (CS), thereby offering a potential explanation of emotional eating (EE). Female participants were randomly presented with 10 different stimuli eliciting either negative or neutral emotional states, with one of these states paired with eating chocolate. Expectancy to eat, desire to eat, salivation, and unpleasantness of experiencing negative emotions were assessed. After conditioning, participants were brought into a negative emotional state and were asked to choose between money and chocolate. Data showed differential conditioned responding on the expectancy and desire measures, but not on salivation. Specific conditioned effects were obtained for participants with a higher BMI (body mass index) on the choice task, and for participants high on EE on the unpleasantness ratings. These findings provide the first experimental evidence for the idea that negative emotions can act as conditioned stimuli, and might suggest that classical conditioning is involved in EE.     

Changes in physical activity among coronary and hypertensive patients: A longitudinal study using the Health Action Process Approach

Objectives: Physical activity (PA) is a key factor in cardiovascular disease prevention. Through the Health Action Process Approach (HAPA), the present study investigated the process of change in PA in coronary patients (CPs) and hypertensive patients (HPs).

Design: Longitudinal survey study with two follow-up assessments at 6 and 12 months on 188 CPs and 169 HPs.

Main outcome measures: Intensity and frequency of PA.

Results: A multi-sample analysis indicated the equivalence of almost all the HAPA social cognitive patterns for both patient populations. A latent growth curve model showed strong interrelations among intercepts and slopes of PA, planning and maintenance self-efficacy, but change in planning was not associated with change in PA. Moreover, increase in PA was associated with the value of planning and maintenance self-efficacy reached at the last follow-up

Conclusions: These findings shed light on mechanisms often neglected by the HAPA literature, suggesting reciprocal relationships between PA and its predictors that could define a plausible virtuous circle within the HAPA volitional phase. Moreover, the HAPA social cognitive patterns are essentially identical for patients who had a coronary event (i.e. CPs) and individuals who are at high risk for a coronary event (i.e. HPs).     

Parents’ Social Status and Children’s Daily Physical Activity: The Role of Familial Socialization and Support

Physical activity is a health relevant factor, particularly in affluent societies where overweight and obesity are increasingly prevalent, even among children. Understanding the development of physical activity patterns in childhood is thus an important issue for health promotion. Following socialization theory, this study describes and explains differences in objectively measured moderate-to-vigorous physical activity (MVPA) in a socially and ethnically mixed sample of 6- to 11-year-old children in Germany. MVPA levels were objectively measured with accelerometers over the course of six consecutive days (Wednesday to Monday). Parents’ attitudes and practices as well as the family’s socio-economic status (SES) were assessed from the parents via questionnaires. Results indicate that MVPA levels of children vary with gender, but not with age and ethnicity. Moreover, parental SES, parental support for the child’s sports activities, parents’ own sport activities and the parents’ belief in sports’ capacities to foster personality development, character building and social integration significantly predict the MVPA level of children. It is concluded that interventions to promote MVPA among children need to take family interactions and lifestyles into account and should address families in socio-economically underprivileged areas.     

Use of evidence in a categorization task: analytic and holistic processing modes

Category learning performance can be influenced by many contextual factors, but the effects of these factors are not the same for all learners. The present study suggests that these differences can be due to the different ways evidence is used, according to two main basic modalities of processing information, analytically or holistically. In order to test the impact of the information provided, an inductive rule-based task was designed, in which feature salience and comparison informativeness between examples of two categories were manipulated during the learning phases, by introducing and progressively reducing some perceptual biases. To gather data on processing modalities, we devised the Active Feature Composition task, a production task that does not require classifying new items but reproducing them by combining features. At the end, an explicit rating task was performed, which entailed assessing the accuracy of a set of possible categorization rules. A combined analysis of the data collected with these two different tests enabled profiling participants in regard to the kind of processing modality, the structure of representations and the quality of categorial judgments. Results showed that despite the fact that the information provided was the same for all participants, those who adopted analytic processing better exploited evidence and performed more accurately, whereas with holistic processing categorization is perfectly possible but inaccurate. Finally, the cognitive implications of the proposed procedure, with regard to involved processes and representations, are discussed.     

The Treatment and Prevention of Depression: Implications for Counseling and Counselor Training

With depression estimated to exist in as much as 10% of the population, it may be the most prevalent problem facing counselors today. S. D. Hollon, M. E. Thase, and J. C. Markowitz (2002) reviewed the extensive research comparing various psychotherapeutic and pharmaceutical approaches to treating depression. They concluded that certain psychotherapy approaches are as effective as medications, but much remains uncertain about effective treatment. This article reviews the authors' analyses and presents implications for the counseling profession.
