Memory training and strategy use in older adults: results from the ACTIVE study

Little is known about the long-term effects of memory training in later life on strategy use. Data from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study (n = 1,401) were used to describe strategy use in a community-dwelling sample of older adults. Strategy clustering scores on verbal list learning tasks of episodic memory were used to test the impact of memory training on strategy use and study longitudinal associations between strategy clustering, memory performance, and everyday functioning. Results suggested that younger, female, white, healthier, and more educated participants show higher strategy clustering scores initially but no characteristics were consistently associated with different trajectories in strategy clustering across all strategy clustering measures together. Memory training had significant immediate effects on all measures of strategy use that were maintained through five years of follow-up. With respect to longitudinal mediation, pre-post training changes in most strategy clustering scores mediate changes in objective memory performance and everyday functioning, implying that strategies can be modified and are closely related to both memory ability and the ability to function independently. This study provides evidence that older adults can be trained to use cognitive strategies, the effects are durable, and strategies are associated with memory and everyday functioning.     

Social presence and service satisfaction: The moderating role of cultural value‐orientation

Two studies examine the role of the cultural value orientation, self‐construal, as a moderator of the relationship between social presence and service satisfaction. Cross‐cultural data are collected in China and the USA to maximize variation on self‐construal. Results suggest that social presence effects vary depending on the consumer's independent self‐construal. Regardless of whether the service encounter is positive or negative, social presence increases the strength of satisfaction or dissatisfaction for low independents but not for high independents.

Electrophysiological indices of emotion processing during retrieval of autobiographical memories by school-age children

We used event-related potentials (ERPs) to examine emotion processing during retrieval of emotional autobiographical memories by school-age children. We initiated processing of the emotional experiences using neutral cue words. On one-third of trials, children were instructed to think of a memory of a negative event, and on another third of trials, they were instructed to think of a memory of a positive event. We then recorded ERPs from 32 electrode sites as the children processed the emotional memories again later in the testing session. The 7- to 10-year-old children generated memories appropriate to the valences specified in the instructions. Neural responses differed as a function of the emotional valence of the events associated with the cues and as a function of gender. In the sample as a whole, differential processing of positive relative to negative and neutral emotions was apparent at posterior electrode sites 1,000–1,500 ms after stimulus onset. For girls, the effect was apparent beginning at 500 ms. No differences between the neural responses to negative and neutral stimuli were observed. At frontal electrode sites, girls evidenced faster processing of positive than of negative emotion, whereas boys evidenced faster processing of negative than of positive emotion. In conclusion, we discuss the possible origins of gender-differential patterns of neural processing.     

Unrequited love: The role of prior commitment,motivation to remain friends,and friendship maintenance

ABSTRACT

This study tested a moderated mediation model that commitment prior to an unrequited love episode will be related to higher levels of friendship maintenance behaviors after the episode and that this relationship will be mediated by the individual’s motivations to remain friends with the rejecter. We predicted that rejection distress would weaken the mediational model among those reporting high distress. Participants wrote about an unrequited love experience as a pursuer and completed measures of pre-unrequited love commitment, rejection distress, motivations to remain friends, and friendship maintenance behaviors. Our results confirmed the moderated mediation model when the motivations to remain friends measure overall score, the interpersonal connection motivation, or the social connections motivation was the mediator. When covariates were added, only the model with the overall motivations score as mediator was supported. These data can help laypersons and mental health professionals understand and potentially repair friendships following an unrequited love episode.     

Mental Disorders,Comorbidity, and Pre‐enlistment Suicidal Behavior Among New Soldiers in the U.S. Army: Results from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)

We examined the associations between mental disorders and suicidal behavior (ideation, plans, and attempts) among new soldiers using data from the New Soldier Study (NSS) component of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS; N = 38,507). Most new soldiers with a pre‐enlistment history of suicide attempt reported a prior mental disorder (59.0%). Each disorder examined was associated with increased odds of suicidal behavior (ORs = 2.6–8.6). Only PTSD and disorders characterized by irritability and impulsive/aggressive behavior (i.e., bipolar disorder, conduct disorder, oppositional defiant disorder, and attention‐deficit/hyperactivity disorder) predicted unplanned attempts among ideators. Mental disorders are important predictors of pre‐enlistment suicidal behavior among new soldiers and should figure prominently in suicide screening and prevention efforts.
