Time of Day Affects Episodic Memory in Older Adults*

ABSTRACT

The neuropsychological test scores of 2,030 cognitively normal older adults were examined to evaluate performance patterns as they related to time of day (TOD) at which testing was initiated. Multiple regression analyses were used to examine the association of TOD with scores on seven neuropsychological tests used in the clinical evaluation of dementia. Episodic memory performance was significantly related to TOD, while memory span and verbal fluency were not. Best performance occurred during early morning hours and late afternoon; worst performance occurred mid-day (i.e., noon). These findings may have implications for clinical assessment, the design of research on dementia, and the daily functioning of older adults.     

War exposure and post-traumatic stress as predictors of Portuguese colonial war veterans' physical health

The relationship between war exposure and post-traumatic stress disorder (PTSD) has been largely investigated but the impact of the combat experience on physical health has only recently merited attention. The authors investigated the relationship between war exposure and psychological and physical health among 350 Portuguese colonial war veterans. The role of current PTSD symptoms as a mediator of these relationships was also investigated. The results showed that 39% of the veterans met criteria for current PTSD diagnosis and psychological distress was present in half of the sample. Pain, fatigue, and sleep problems were the most reported physical symptoms and mental health and gastro-intestinal problems, the most reported illnesses. Combat exposure variables were significant predictors of current health. The results indicated that veterans with higher exposure to war trauma maintained higher current levels of psychological distress and presented more physical health problems and physical symptoms than those less exposed. Mediation analyses showed that current PTSD was a full mediator of the relationship between war exposure and physical health outcomes.     

Bidirectional Relationships Between Parenting Stress and Child Coping Competence: Findings From the Pace Study

The present study was designed to evaluate the bidirectional relationships between parenting stress and child coping competence. Data from a diverse sample of 610 parents enrolled in the parenting our children to excellence program was used to evaluate whether parenting stress negatively contributes to affective, achievement, and social coping competence in preschoolers, as well as whether child coping competence predicts parenting stress; after accounting for child disruptive behavior. Results from cross-lagged panel analyses demonstrated a bidirectional relationship, such that parenting stress predicted later child coping competence and child coping competence predicted later parenting stress. Assessment of ethnicity differences indicated that child coping continues to have a long-term impact on parenting stress, regardless of parent ethnicity. The same relationship did not hold for earlier parenting stress on later child coping competence, however, indicating a bidirectional relationship for African American families, but not for their European American counterparts. The relationship between parenting stress and child coping competence is discussed with respect to their conceptual and clinical implications. Suggestions for parent training intervention and prevention programs are given.     

Child and parental outcomes of a group parenting intervention for Latino families: A pilot study of the CANNE program

Criando a Nuestros Ni?os hacia el éxito (CANNE) is the Spanish adaptation of Parenting Our Children to Excellence (PACE). A pilot study conducted with 124 parents of preschoolers (mostly recent Mexican immigrants) provides preliminary evidence for the community acceptability and efficacy of CANNE. Eighty-eight of the 124 parents who enrolled in the program attended one or more of the 8 sessions (17% attended 1 session, 11% attended 2-4 sessions, and 72% attended 5 or more sessions), participated actively in sessions, and expressed high degrees of program satisfaction. Over time, parents improved on measures of harsh-inconsistent discipline, and children improved on social competence and social-communication skills. When high-versus-low attenders were compared, high attenders (parents who attended 4 sessions or more) reported greater increases than low attenders in their appropriate-positive parenting practices and clear expectations, and in their children's social competence and communication skills, and they reported greater decreases in their harsh-inconsistent discipline and in their children's aggressiveness and hyperactivity. Some of these changes were evident by the end of the program, whereas others became apparent (or stronger) over a 3-month follow-up period. These encouraging results point to the need for an efficacy study that assesses how well CANNE can help larger numbers of Latino parents in the important task of bringing up their young children in the United States.     

The effect of self-distancing on adaptive versus maladaptive self-reflection in children

Although children and adolescents vary in their chronic tendencies to adaptively versus maladaptively reflect over negative feelings, the psychological mechanisms underlying these different types of self-reflection among youngsters are unknown. We addressed this issue in the present research by examining the role that self-distancing plays in distinguishing adaptive versus maladaptive self-reflection among an ethnically and socioeconomically diverse sample of fifth-grade public schoolchildren. Children were randomly assigned to analyze their feelings surrounding a recent anger-related interpersonal experience from either a self-immersed or self-distanced perspective. They then rated their negative affect and described in writing the stream of thoughts they experienced when they analyzed their feelings. Children's stream-of-thought essays were content analyzed for the presence of recounting statements, reconstruing statements, and blame attributions. Path analyses indicated that children who analyzed their feelings from a self-distanced perspective focused significantly less on recounting the "hot," emotionally arousing features of their memory (i.e., what happened to me?) and relatively more on reconstruing their experience. This shift in thought content--less recounting and more reconstruing--led children in the self-distanced group to blame the other person involved in their recalled experience significantly less, which in turn led them to display significantly lower levels of emotional reactivity. These findings help delineate the psychological mechanisms that distinguish adaptive versus maladaptive forms of self-reflection over anger experiences in children. Their basic findings and clinical implications are discussed.     

The effects of culture and friendship on rewarding honesty and punishing deception

The present research explores whether the type of relationship one holds with deceptive or honest actors influences cross-cultural differences in reward and punishment. Research suggests that Americans reward honest actors more than they punish deceptive perpetrators, whereas East Asians reward and punish equally (Wang & Leung, 2010). Our research suggests that the type of relationship with the actor matters for East Asians, but not for Americans. East Asians exhibit favoritism toward their friends by rewarding more than punishing them, but reward and punish equally when the actors are strangers (Experiment 1 and 2); Americans reward more than they punish regardless of the type of relationship (Experiment 2). Furthermore, the findings were replicated when the proposed mechanism – social mobility – was manipulated within the same culture (Experiment 3). We discuss the implications of these findings for understanding how friends versus strangers are rewarded and punished in an increasingly relationally complex world.     

Command use and compliance in staff communication with elderly residents of long-term care facilities

Verbal communication between nursing assistants and individuals with dementia can be challenging, particularly during hands-on caregiving tasks. Although there are many aspects of verbal communication that can affect the quality of an interaction, one potentially important communication variable is the types of commands issued by nursing assistants when they need a resident to complete a task. The purpose of this study was to examine the kinds of commands used by nursing care staff when they interact with patients with dementia during activities of daily living. Commands were categorized according to their feasibility/specificity as well as form. An additional goal of this study was to measure compliance and noncompliance rates associated with the various categories of commands. Results indicate that alpha commands (clear, concise, and feasible) account for higher compliance and less noncompliance compared with beta commands (ambiguous, interrupted, and not feasible). In addition, commands that are stated directly, that clarify a previous command, and that are repeated exactly produce better compliance. It is concluded that training nursing staff to change the types of commands they provide during caregiving tasks may reduce distress experienced by both staff and residents.     

Overvaluation of shape and weight among overweight children and adolescents with loss of control eating

Little is known about the phenomenology of pediatric loss of control (LOC) eating. Overvaluation of shape and weight, however, appears to be diagnostically meaningful among binge eating adults. We explored the significance of shape and weight overvaluation among children and adolescents with LOC eating. Participants (n = 526) included 149 overweight youth with LOC eating and 377 overweight controls (CON). Participants were categorized as those reporting at least moderate overvaluation (LOC-Mod, n = 74; CON-Mod, n = 106) or less than moderate overvaluation (LOC-Low, n = 75; CON-Low, n = 271), and compared on measures of eating-related and general psychopathology. LOC-Mod evidenced lower self-esteem than CON-Low, and greater behavioral problems than CON-Mod and CON-Low, but did not differ from LOC-Low in these domains. With the exception of LOC-Low and CON-Mod, all groups differed on global eating-disorder severity, with LOC-Mod scoring the highest. Overvaluation of shape and weight appears to be of questionable importance in defining subtypes of youth with LOC eating. However, as overvaluation and LOC eating each independently predicts eating-disorder onset, their confluence may confer even further risk for eating-disorder development. Longitudinal studies should address this possibility. Developmentally appropriate discussion about body image disturbance may be indicated in interventions targeting pediatric LOC eating and/or obesity.     

Childhood emotional abuse and attachment processes in the dyadic adjustment of dating couples

In an effort to improve understanding of the mechanisms that link early maltreatment to later outcomes, this study investigated the mediation effects of adult attachment processes on the association between childhood emotional abuse and later romantic relationships among heterosexual couples. College students and their dating partners (N = 310; 155 couples) completed the Childhood Trauma Questionnaire, Experiences in Close Relationship Scale, and Dyadic Adjustment Scale. Using the Actor–Partner Interdependence Model (Kenny, Kashy, & Cook, 2006), multilevel modeling results indicated that memories of childhood emotional abuse reported by both students and their partners were significantly associated with attachment strategies, as well as romantic relationship quality. Findings supported hypothesized mediation effects of attachment anxiety and avoidance.     

The list length effect in recognition memory: an analysis of potential confounds

The list length effect in recognition memory refers to the finding that recognition performance for a short list is superior to that for a long list. The list length effect is consistent with the predictions of item noise models, but context noise models predict no effect. Recently, it has been argued that if potential confounds are controlled, the list length effect is eliminated. We report the results of two experiments in which we looked at the role of attention and the remember–know task in the detection of the list length effect. We conclude that there is no list length effect when potential confounds are controlled and that it is the design used to control for attention that is most vital.
