Cognitively impaired older adults exhibit comparable difficulties on naturalistic and laboratory prospective memory tasks

Prospective memory, or remembering future intentions, is critical for independent living for all ages, but especially older adults. Previous laboratory research has found that cognitively impaired older adults may have particular difficulties with prospective memory, but previous studies have not examined whether these difficulties occur in everyday life. In normal ageing, a dissociation between settings has been observed, with older adults selectively impaired in laboratory (but not naturalistic) contexts. Consequently, in the present study 15 cognitively impaired older adults were compared to demographically matched controls on laboratory and naturalistic measures of prospective memory. The results indicated that the cognitively impaired group performed more poorly on both measures, with the magnitude of the deficit comparable across setting. These results indicate that for older adults who present with cognitive impairment prospective memory deficits observed in laboratory settings may be a valid indicator of difficulties experienced executing delayed intentions in everyday life.

The Impact of Anonymity on Responses to Sensitive Questions1

To estimate frequencies of behaviors not carried out in public view, researchers generally must rely on self‐report data. We explored 2 factors expected to influence the decision to reveal: (a) privacy (anonymity vs. confidentiality) and (b) normalization (providing information so that a behavior is reputedly commonplace or rare). We administered a questionnaire to I55 undergraduates. For 79 respondents, we had corroborative information regarding a negative behavior: cheating. The privacy variable had an enormous impact; of those who had cheated, 25% acknowledged having done so under confidentiality, but 74% admitted the behavior under anonymity. Normalization had no effect. There were also dramatic differences between anonymity and confidentiality on some of our other questions, for which we did not have validation.     

Symptoms,blood-pressure information and mood effects on symptom recall

Abstract

After completion of an illness symptom checklist (PILL) covering the previous three months, 97 nor-motensives were allocated to either experimental (false pressor feedback, n=42), or information control (accurate pressor feedback, n = 55), groups. The median reported symptom score divided high from low symptom subjects. All were given standard cuff blood pressure (BP) assessment and were normotensive. However, experimental subjects were misinformed that their BP was raised while information control subjects were told their BP was normal. Subsequently, subjects completed the state anxiety form of the State-Trait Personality Inventory, the PILL, and were asked about their belief of the ascribed BP label (normo/hypertensive) and then any perceived causal relationship between their BP and symptoms. Experimental subjects had significantly higher anxiety scores but no change in symptom recall after pressor feedback, whereas control subjects showed lower anxiety scores and decreases in symptom recall.

A post hoc treatment control (no pressor information) group (n = 20) excluded effects of BP labeling on post-BP scores, and a post hoc symptom control group (n = 55) ensured that symptom levels were representative of the normal population. The majority of subjects in both groups rejected any association between BP labels and symptoms. Data are discussed in the light of Leventhal's models of illness representation.     

Opening the Creative Mind of High Need for Cognitive Closure Individuals through Activation of Uncreative Ideas

Drawing on the integrative system theory of creativity combining the person, process, and press perspectives, this research offers the first evidence of how high-need-for-cognitive-closure (NFC) individuals’ creative mind can be opened up, by making them become more cognizant of uncreative ideas as consensually invalid solutions to creative problems. A validation study was conducted to first establish the utility of a newly developed chocolate design task. In the second study, half of the participants were made aware of conventional chocolate designs by drawing these designs before generating a revolutionized design of chocolate; the other half did not have to draw out the conventional designs first. Results confirmed that, given the opportunity to cognize uncreative solutions, high-NFC participants who had a higher creative ideation potential became the most creative. Their low-NFC counterparts, however, did not seem to benefit from the trigger of uncreative solutions. The implication that holding onto a chronic motive to attain cognitive closure or epistemic certainty is not necessarily detrimental to creative performance was discussed.     

What Mediates Links Between Age and Well-being? A Test of Social Support and Interpersonal Conflict as Potential Interpersonal Pathways

We examined potential nonlinear links between age and subjective well-being, and the interpersonal processes (i.e., support, conflict) responsible for such links. One hundred forty-four men and women between the ages of 30–70 completed measures of satisfaction with life, social support (interpersonal support evaluation list), and social negativity (test of negative social exchanges). Nonlinear regression analyses revealed a significant quadratic trend between age and satisfaction with life (SWL, p = .01) where age was associated with lower SWL in the young to middle-aged sample, but higher SWL in the middle-age to older adult sample. Analyses further revealed that interpersonal tensions statistically mediated the nonlinear links between age and SWL. These data suggest that negative interpersonal exchanges may be important contributors to well-being at midlife.     

Improving sleep with mindfulness and acceptance: A metacognitive model of insomnia

While there is an accumulating evidence to suggest that therapies using mindfulness and acceptance-based approaches have benefits for improving the symptoms of insomnia, it is unclear how these treatments work. The goal of this paper is to present a conceptual framework for the cognitive mechanisms of insomnia based upon mindfulness and acceptance approaches. The existing cognitive and behavioral models of insomnia are first reviewed and a two-level model of cognitive (primary) and metacognitive (secondary) arousal is presented in the context of insomnia. We then focus on the role of metacognition in mindfulness and acceptance-based therapies, followed by a review of these therapies in the treatment of insomnia. A conceptual framework is presented detailing the mechanisms of metacognition in the context of insomnia treatments. This model proposes that increasing awareness of the mental and physical states that are present when experiencing insomnia symptoms and then learning how to shift mental processes can promote an adaptive stance to one's response to these symptoms. These metacognitive processes are characterized by balanced appraisals, cognitive flexibility, equanimity, and commitment to values and are posited to reduce sleep-related arousal, leading to remission from insomnia. We hope that this model will further the understanding and impact of mindfulness and acceptance-based approaches to insomnia.     

Knowledge and use of memory strategies in amnestic mild cognitive impairment

Despite the inclusion of memory strategy training in many interventions for amnestic mild cognitive impairment (aMCI), little research has directly examined knowledge and use of memory strategies in aMCI and their relationship to memory performance in order to guide the development of targeted interventions. The present study aimed to compare strategy knowledge and use between an aMCI and a healthy older adult (HOA) sample, and to determine the contribution of strategy knowledge and use to memory performance in each of these groups. The sample comprised 37 aMCI and 52 HOA participants aged over 60 years. All participants completed questionnaires to assess strategy knowledge and self-reported use of internal and external strategies in everyday life. In addition, strategy use was observed on the measures of retrospective and prospective memory performance (the CVLT-II and the CAMPROMPT). The aMCI group demonstrated decreased strategy knowledge and observed use of internal strategies, although equivalent observed use of external strategies compared with the HOA group. Furthermore, they reported equivalent use of both internal and external strategies. Observed use of strategies was significantly associated with retrospective memory performance for both groups and prospective memory performance for the aMCI group, supporting the inclusion of strategy training in interventions.     

Poverty and health: the mediating role of perceived discrimination

Social-class discrimination is evident in many societies around the world, but little is known about its impact on the poor or its role as an explanatory variable in the link between socioeconomic status and health. The current study tested the extent to which perceived discrimination explains socioeconomic gradients in physical health. Participants were 252 adolescents (51% male, 49% female; mean age = 17.51 years, SD = 1.03 years) who participated in Wave 3 of an ongoing longitudinal study focusing on the developmental consequences of rural poverty. Physical health was operationalized as allostatic load, a measure of cumulative wear and tear on the body caused by overactivation of physiological systems that respond to stress. Mediation analyses suggested that 13% of the effect of poverty on allostatic load is explained by perceived discrimination. The findings suggest that social-class discrimination is one important mechanism behind the influence of poverty on physical health.     

Does severity predict distress? The relationship between subjective and objective measures of appearance and psychological adjustment,during treatment for facial lipoatrophy

The intuitive or lay belief that the severity of a disfiguring condition predicts psychological distress is not demonstrated in clinical practice, nor in research studies. This within group study used standardised measures repeated at six month intervals, to investigate the relationship between subjective and objective measures of appearance and psychological adjustment in 51 patients undergoing treatment for facial lipoatrophy using a synthetic filler, Newfill^®. Results demonstrate a dissociation between objective and subjective measures with only subjective assessment predicting psychological outcomes. It is recommended that Moss's (2005) hypothesis of discrete group membership (normal/not normal) should be adapted to include an internal standard for comparison, and that all evaluations of treatment modifying disfigurement should include a standardised subjective measure of appearance.
