A single bout of resistance exercise can enhance episodic memory performance

Acute aerobic exercise can be beneficial to episodic memory. This benefit may occur because exercise produces a similar physiological response as physical stressors. When administered during consolidation, acute stress, both physical and psychological, consistently enhances episodic memory, particularly memory for emotional materials. Here we investigated whether a single bout of resistance exercise performed during consolidation can produce episodic memory benefits 48 h later. We used a one-leg knee extension/flexion task for the resistance exercise. To assess the physiological response to the exercise, we measured salivary alpha amylase (a biomarker of central norepinephrine), heart rate, and blood pressure. To test emotional episodic memory, we used a remember-know recognition memory paradigm with equal numbers of positive, negative, and neutral IAPS images as stimuli. The group that performed the exercise, the active group, had higher overall recognition accuracy than the group that did not exercise, the passive group. We found a robust effect of valence across groups, with better performance on emotional items as compared to neutral items and no difference between positive and negative items. This effect changed based on the physiological response to the exercise. Within the active group, participants with a high physiological response to the exercise were impaired for neutral items as compared to participants with a low physiological response to the exercise. Our results demonstrate that a single bout of resistance exercise performed during consolidation can enhance episodic memory and that the effect of valence on memory depends on the physiological response to the exercise.     

On Lions and Adolescents: Affective Temperaments and the Influence of Negative Stimuli on Memory

The present study investigated the relation between reaction to negative stimuli and memory for stimuli. The relation was further investigated using as a framework individuals’ affective temperaments (AFTs). Eighty adolescents participated in the study. The AFTs are based on selfreported affect and categorizes individuals in four temperaments: self-actualizing, high affective, low affective and self-destructive. Reaction to negative stimuli was measured by interpretation of specific words in a short story. Two days later, participants were presented with a list of words and asked which of them were present in the short story. Individuals’ AFTs were expected to predict the promotion of pleasure or the prevention of displeasure. On a general level, reaction to negative stimuli predicted memory for negative, positive and neutral words. At an individual level, self-actualizers and high affectives’ negative reaction predicted the memory of positive words (i.e., promotion). In contrast, low affectives’ negative and positive reaction predicted the memory of neutral words (i.e., prevention).     

Self-Efficacy for Affect Regulation as a Predictor of Future Life Satisfaction and Moderator of the Negative Affect—Life Satisfaction Relationship

Life satisfaction is an important index of mental health and also predicts other important outcomes such as longevity and decreased mortality. Negative affect has a unique inverse relationship with life satisfaction across the life span. Therefore, determining psychological factors that uniquely predict future life satisfaction and that reduce the trait negative affect—life satisfaction relationship is theoretically and clinically important. In light of recent evidence from long-term longitudinal studies that self-efficacy for regulation of negative emotions (SERN) predicts higher future life satisfaction, as well as evidence from a cross-sectional study that a subtype of SERN—self-efficacy for regulating anger—buffers the relationship between trait negative affect and life satisfaction, we tested whether SERN and subtypes of SERN predicted higher life satisfaction and buffered the negative affect—life satisfaction relationship longitudinally over short time periods. After controlling for time 1 life satisfaction, higher time 1 self-efficacy for regulating despondency and distress (SEDes) predicted higher future life satisfaction over average time periods of 17 days (N = 127), 32 days (N = 83), and 41 days (N = 65) among college students. However, in post hoc exploratory regressions that included self-efficacy for experience and expression of positive emotions (SEPos), SEDes predicted higher time 2 life satisfaction, but only SEPos uniquely predicted higher time 3 and time 4 life satisfaction.     

A Longitudinal Study of Forgiveness and Post-Disclosure Experience in Mixed Orientation Couples

Mixed-orientation couples (MOC) are under-represented in the literature. Often when sexual minorities disclose their sexual orientation it is a stressful experience for their spouse who progresses through stages and experiences both negative and supportive responses as they address disclosure-related issues. Participants completed an online survey and then repeated the same process a year later to measure changes in forgiveness and experience. Forgiveness was shown to play a role in how spouses progress through the post-disclosure stages. In addition, forward movement was seen in both forgiveness and stages over the course of one year. Implications for therapy with MOC are discussed.     

Parental Reports of Executive Dysfunction in Adolescents with Bipolar Disorder

Bipolar disorder (BPD) is a serious mental illness that affects children and adolescents at a rate similar to that seen in adults. Extremely little is known, however, about cognitive functioning in childhood and adolescent BPD. The present study represents an initial effort to examine executive functioning in adolescents with BPD who are in a manic or mixed mood state, by collecting data from caregivers about the participants' performance on everyday tasks thought to be mediated by executive functioning abilities, using the Behavior Rating Inventory of Executive Function. In comparison to healthy volunteers, adolescents with BPD exhibited significant elevations across all of the measured functional domains. These elevations were evident even in adolescents with BPD who did not have comorbid ADHD, although they were most prominent in those with comorbidity. The findings suggest that adolescents with BPD have functional deficits on tasks requiring executive functioning skills that are not explicable solely on the basis of comorbid ADHD.     

Content Analysis: A Comparison of Manual and Computerized Systems

Computerized content analysis is a technique for classifying texts. in personality research it has beer used to make inferences about psychological states and traits of the speaker or writer. Whereas computerized techniques have been increasing in both sophistication and ease of use, questions remain regarding their validity compared to hand-scored scales, in this study, we compare a relatively simple computerized technique; a more sophisticated, context-sensitive computerized approach; and a context-sensitive, human-scored system. Seventy-one subjects, representing four diagnostic groups, provided free-speech samples which were scored according to all three methods. Data from each method were then submitted to discriminant and classification analyses. In comparing the classification performance of the three methods, we found that both computerized methods were more accurate than the human-scored method. The time and cost benefits of computerized systems are discussed.
