Chronic Sorrow in Caregiving Spouses of Patients with Alzheimer's Disease

The article focuses on the concept of chronic sorrow in a sample of individuals with Alzheimer's disease (AD) and their caregiving spouses. A study was designed to determine the long-term grief or chronic sorrow that develops in caregiving spouses and to increase knowledge of the nature of chronic sorrow. Utilizing the Burke Nursing Consortium for Research on Chronic Sorrow questionnaire and Lindgren's (1996) study as a prototype, the author discovered that repetitive feelings of sorrow and distress appear in caregivers when major disruptive changes occur in their lives due to the persistent demands caused by the illness. Continual coping skills are needed to keep caregivers from being mentally, emotionally, and physically depleted. The findings of this study are consistent with Lindgren's 1996 study of chronic sorrow in persons with Parkinson's disease.     

Cognitive consequences of playing brain-training games in immersive virtual reality

The goal of the present study was to examine the effects of playing an immersive virtual reality game that included a collection of gamified cognitive tasks, Cerevrum, on specific components of cognition, including perceptual attention, mental rotation, working memory, visualization, visual field of view, and visual processing speed. Participants completed a pretest of cognitive assessments, played one of the two mini-games within Cerevrum (Stardust or Heroes) for 1.5 hr over three 30-min sessions and then completed a posttest of cognitive assessments and a questionnaire about interest and engagement during the game. An inactive control group completed only the pretest and posttest. Results showed no significant differences among the Heroes group, Stardust group, and control group on the posttest scores, even when controlled for pretest scores. These findings do not support the claim that playing brain-training games for a short period results in transfer of cognitive training to nongame venues.     

Character Strengths and Life Satisfaction in Later Life: an Analysis of Different Living Conditions

The aim of this study was to explore the role of character strengths and their associations to life satisfaction in older people. We were interested in studying several transitions that are specific for older people: aging, retirement, living alone, and being widowed. We examined the relationships of these demographic characteristics and living conditions with character strengths and studied their effects on the association of character strengths with life satisfaction. In a cross-sectional analysis, 15,598 older adults (aged 46–93 years) who had completed measures on character strengths, life satisfaction, and demographic characteristics and living conditions were selected from an existing database. Overall, analyses revealed positive associations of most character strengths with age, and higher scores in most character strengths for the employed (vs. the retired) and those living with a partner (vs. those living alone), while only few relationships with being widowed (vs. being married) were observed. Further, the contribution of character strengths to life satisfaction generally decreased slightly with age, but increased for certain character strengths, such as modesty or prudence. Also, stronger relationships between several character strengths and life satisfaction were found for retired people and those living alone, while being widowed did not affect these relationships. The results demonstrate how character strengths might contribute to the life satisfaction of older adults in various living conditions and thereby offer a starting point for strengths-based programs in later life.

     

A 1-year follow-up of an experimental study of a self-management arthritis programme with an added exercise component of clients with osteoarthritis of the knee

The aim was to assess the self-efficacy and health outcomes of an adopted Arthritis Self-Management Programme (ASMP) among osteoarthritic knee sufferers in Hong Kong at 1 year. An experimental study with 95 participants assigned randomly to the intervention (n=45) or control group (n=50). Seventy-seven (81.1%) participants joined at least one out of three follow-ups in the 12 month period. Participants in the intervention group received a 6-week ASMP with an added exercise component in two general clinics. Outcome measures included arthritis self-efficacy (ASE) and health outcomes including pain and fatigue rating, self-rated health, daily activities limitation and number of unplanned arthritis-related medical consultations. Mean change (12 months minus baseline) and the effect size of the outcome measures were calculated by Mann-Whitney U test and nQuery Advisor 4.0. At 12 months, there were significant reductions of current pain (p=0.0001), pain at night (p=0.001), pain during walking (p=0.01) and number of unplanned arthritis-related medical consultations (p=0.03) and a significant increase in ASE for pain (p=0.01) and other symptoms (p=0.02) and self-rated health (p=0.04) among the intervention group but not for the control group. However, there were similarities in outcome measures of pain while switching from a sitting to a standing position, fatigue rating and physical functional limitation (p=0.15; p=0.22 and p=0.91, respectively) for both groups. Our findings add to the evidence that the modified arthritis empowering programme improved perception of control of osteoarthritis and three health outcomes after 12 months of treatment.     

Haptic search is more efficient when the stimulus can be interpreted as consisting of fewer items

In a typical haptic search task, separate items are presented to individual fingertips. The time to find a specific item generally increases with the number of items, but is it the number of items or the number of fingers that determines search time? To find out, we conducted haptic search experiments in which horizontal lines made of swell paper were presented to either two, four or six of the participants' fingertips. The task for the participant was to lift the finger under which they did not feel (part of) a line. In one of the conditions separate non-aligned lines were presented to the fingertips so that the number of items increased with the number of fingers used. In two other conditions the participants had to find an interruption in a single straight line under one of the fingertips. These conditions differed in the size of the gap. If only the number of items in the tactile display were important, search times would increase with the number of fingers in the first condition, but not depend on the number of fingers used in the other two conditions. In all conditions we found that the search time increased with the number of fingers used. However, this increase was smaller in the single line condition in which the gap was large enough for one finger to not make any contact with the line. Thus, the number of fingers involved determines the haptic search time, but search is more efficient when the stimulus can be interpreted as consisting of fewer items.     

Theory-of-mind, cognitive development, and children's interpretation of anxiety-related physical symptoms

The present study investigated developmental patterns in children's interpretation of anxiety-related physical symptoms and emotional reasoning, and to what extent these phenomena are influenced by children's level of cognitive development. A large sample of 4-13-year-old children (N=358) were exposed to vignettes in which the presence and absence of physical symptoms was systematically varied. In addition, children completed a series of conservation tasks and a theory-of-mind-test. Results demonstrated that from the age of 7, children were increasingly able to link physical symptoms to anxiety. Furthermore, cognitive development appeared to enhance children's ability to interpret physical symptoms as a sign of anxiety. Further, children's tendency to infer danger from vignettes with physical symptoms (i.e., emotional reasoning) was already prominent in 4-6-year-olds. The implications for physical symptom-based theories of childhood anxiety are briefly discussed.     

Power and overconfident decision-making

Five experiments demonstrate that experiencing power leads to overconfident decision-making. Using multiple instantiations of power, including an episodic recall task (Experiments 1–3), a measure of work-related power (Experiment 4), and assignment to high- and low-power roles (Experiment 5), power produced overconfident decisions that generated monetary losses for the powerful. The current findings, through both mediation and moderation, also highlight the central role that the sense of power plays in producing these decision-making tendencies. First, sense of power, but not mood, mediated the link between power and overconfidence (Experiment 3). Second, the link between power and overconfidence was severed when access to power was not salient to the powerful (Experiment 4) and when the powerful were made to feel personally incompetent in their domain of power (Experiment 5). These findings indicate that only when objective power leads people to feel subjectively powerful does it produce overconfident decision-making.     

An eye movement analysis of the spatial contiguity effect in multimedia learning

In three studies, eye movements of participants were recorded while they viewed a single-slide multimedia presentation about how car brakes work. Some of the participants saw an integrated presentation in which each segment of words was presented near its corresponding area of the diagram (integrated group, Experiments 1 and 3) or an integrated presentation that also included additional labels identifying each part (integrated-with-labels group, Experiment 2), whereas others saw a separated presentation in which the words were presented as a paragraph below the diagrams (separated group, Experiments 1 and 2) or as a legend below the diagrams (legend group, Experiment 3). On measures of cognitive processing during learning, the integrated groups made significantly more eye-movements from text to diagram and vice versa (integrative transitions; d = 1.65 in Experiment 1, d = 0.85 in Experiment 2, and d = 1.44 in Experiment 3) and significantly more eye-movements from the text to the corresponding part of the diagram (corresponding transitions; d = 2.02 in Experiment 1 and d = 1.35 in Experiment 3) than the separated groups. On measures of learning outcome the integrated groups significantly outperformed the separated groups on transfer test score in Experiment 1(d = .80) and Experiment 2 (d = .73) but not in Experiment 3 (d = .35). Spatial contiguity encourages more attempts to integrate words and pictures and enables more successful integration of words and pictures during learning, which can result in meaningful learning outcomes.
