Absence of Ankle Stiffening While Standing in Focus and Cognitive Task Conditions in Older Adults

Abstract

Research suggests that an external focus or cognitive task may improve postural control. Removing attention from movement production may promote automaticity, or the tasks may promote ankle stiffening. To investigate these two theories, twenty older adults stood while performing baseline standing, internal focus, external focus, and two cognitive tasks. Changes in postural control occurred in external focus and cognitive task conditions compared to baseline and internal focus, while no change occurred in cocontraction indices. This suggests that an external focus and cognitive task can improve postural control in older adults. Since no change occurred in cocontraction indices across conditions, this suggests that stiffening cannot explain these changes. Instead, changes could be due to automaticity of sway.     

Stepping Responses in Young and Older Adults Following a Perturbation to the Support Surface During Gait

The objective of this work was to investigate the influence perturbation direction has on postural responses during overground gait, and whether these responses are age related. Differences in stepping patterns following perturbations of the support surface were examined in the frontal and sagittal planes during forward walking. Eleven young and 10 older adults completed Mini BESTest, hip strength tests, and 45 perturbed walking trials, triggered on heel contact. Lateral perturbations were more challenging to postural stability for both groups. Step length measures showed young adults recovered in the step proceeding the perturbation, while older adults needed additional steps to regain balance. Young adults arrested center of mass movement by producing larger step widths than older adults following the support surface perturbation.

Useful Field of View and Other Neurocognitive Indicators of Crash Risk in Older Adults

Older adults represent a rapidly growing segment of the driving population. Although most older drivers are safe, research has shown that this group has more crashes per mile driven than most other age groups. The purpose of the present investigation was to examine the utility of a set of commonly used neuropsychological/cognitive tests in comparison to a newer measure of visual attention (Useful Field of View; UFOV®) in predicting state-recorded, at-fault crashes over the previous five years in a group of older adult drivers. Participants (N = 239) completed tests of mental status, visual attention, memory, and UFOV®. Results show that among all cognitive tests administered, UFOV® was most strongly related to crash involvement, with high levels of sensitivity (86.3%) and specificity (84.3%) at the standard cutoff score of 40% reduction. Practical implications for the assessment of crash risk are discussed.     

老年人的朋友参照效应

采用自我参照效应范式探讨老年人朋友参照效应的特点。城市老年人和农村老年人各36人参加实验1, 结果表明：(1)城乡老年人都表现出朋友参照效应; (2)与农村老年人相比, 城市老年人朋友参照效应指标显著高于自我参照效应指标。城市教育程度较高与教育程度较低老年人各36人参加实验2, 结果发现, 与城市教育程度较低的老年人相比, 城市教育程度较高的老年人朋友参照效应指标高于自我参照效应指标, 表明教育程度对朋友参照效应有显著影响。由此推断, 老年人会将朋友包含于自我图式之内, 并且教育程度会影响朋友在自我图式中的地位。     

Intraindividual Variability of Neuromotor Function Predicts Falls Risk in Older Adults and those with Type 2 Diabetes

This study was designed to examine the effect of increasing age and type 2 diabetes on the average responses and inter- and intraindividual variability of falls risk, reaction time, strength, and walking speed for healthy older adults and older persons with type 2 diabetes (T2DM). Seventy-five older individuals (controls) and 75 persons with T2DM aged between 50 and 79 years participated in the study. Assessments of falls risk, reaction time (RT), knee extension strength, and walking speed were conducted. The results revealed that advancing age for both control and T2DM groups was reflected by a progressive increase in falls risk, decreased leg strength and a decline (i.e., slowing) of reactions and gait speed. Conversely, the level of intraindividual variability for the RT, strength and gait measures increased with increasing age for both groups, with T2DM persons tending to be more variable compared to the healthy controls of similar age. In contrast to the intraindividual changes, measures of interindividual variability revealed few differences between the healthy elderly and T2DM individuals. Taken together, the findings support the proposition that intraindividual variability of neuromotor measures may be useful as a biomarker for the early detection of decline in physiological function due to age or disease.     

注意分散对老年人错误记忆的影响

该实验以经典DRM词表为实验材料,采用简化后的联合范式来探讨注意资源对老年人错误记忆的影响。比较老年人和青年人在注意集中和注意分散条件下的错误记忆成绩。结果发现,老年组的虚报率显著高于青年人的虚报率,特别在注意集中条件下。更重要的是,老年人在注意集中条件下的虚报率与青年人在注意分散条件下的虚报率相比无显著差异,同时两种条件下的判断标准差异也不显著。结果显示,老年人相比于青年人有更多错误记忆的原因可能是注意资源的不足。

The Dynamics of Visual Reweighting in Healthy and Fall-Prone Older Adults

Multisensory reweighting (MSR) is an adaptive process that prioritizes the visual, vestibular, and somatosensory inputs to provide the most reliable information for postural stability when environmental conditions change. This process is thought to degrade with increasing age and to be particularly deficient in fall-prone versus healthy older adults. In the present study, the authors investigate the dynamics of sensory reweighting, which is not well-understood at any age. Postural sway of young, healthy, and fall-prone older adults was measured in response to large changes in the visual motion stimulus amplitude within a trial. Absolute levels of gain, and the rate of adaptive gain change were examined when visual stimulus amplitude changed from high to low and from low to high. Compared with young adults, gains in both older adult groups were higher when the stimulus amplitude was high. Gains in the fall-prone elderly were higher than both other groups when the stimulus amplitude was low. Both older groups demonstrated slowed sensory reweighting over prolonged time periods when the stimulus amplitude was high. The combination of higher vision gains and slower down weighting in older adults suggest deficits that may contribute to postural instability.

Comparison of Privacy Consciousness Between Younger and Older Adults

The degree of being conscious about privacy for the self and others is known as privacy consciousness. This study aimed to compare privacy consciousness between younger and older adults. Japanese younger (n = 166) and older (n = 145) adults were requested to rate all items in the Privacy Consciousness Scale, which assessed their degree of consciousness about privacy for the self and others and behaviors for maintaining privacy based on this consciousness. Results indicated that older adults scored lower on Consciousness Regarding Privacy of Others and higher on Behaviors Regarding Privacy of Others than younger adults. However, no significant difference was found in Consciousness and Behaviors Regarding Privacy of the Self between younger and older adults.     

Counseling Older Adults with Dementia: A Survey of Therapists in Massachusetts

Although much has been written about therapeutic interventions with caregivers, little is known about the counseling services that are available for victims of dementia. The present study was designed to explore community mental health center (CMHC) services and therapists' experiences in providing psychotherapy to this population in Massachusetts. Only 27 of the 36 CMHCs in the state reported providing mental health services to older adults with a dementing illness. A survey of therapists who specialized in working with older adults found that the percentage of older adult clients estimated to have dementia averaged about half of their caseload. Older persons in the early phase of a dementing illness were most frequently referred for depression and anxiety, whereas those with moderate decline were most frequently referred for management of disruptive behavior. The most common services provided to clients with dementia consisted of assessment and individual counseling. The latter finding indicates a discrepancy between what is practiced and the professional literature. Most of the psychotherapy described in the literature concerns group interventions, which were rarely provided by the mental health centers in Massachusetts. The centers tended to offer individual counseling; however, little information on how to provide this form of treatment can be found.     

Heart Rate Variability and Sustained Attention in ADHD Children

The major goal of the current study was to investigate the association between continuous performance tests (CPTs) and the heart rate variability (HRV) of attention deficit hyperactivity disorder (ADHD) children. The HRV, specifically the 0.10-Hz component, may be considered to be a psychophysiological index of effort allocation (motivation): The less effort the subject allocates, the greater the 0.10-Hz component. Results indicated that, compared to controls, ADHD subjects had a greater 0.10-Hz component, which was associated with poor test performance over time. Thus, using a psychophysiological measure, we were able to confirm the clinical concept of ADHD from a motivational perspective.     

When Psychologists Work with Older Adults: A Survey of Ethical Beliefs and Practices

Despite the number of publications concerning legal and ethical issues faced by psychologists, and despite the increased interest in addressing specific concerns related to aging, little is known about the actual beliefs and practices of psychologists when they work with older adults. Given the changing demographics in the United States, many mental health professionals will have contact with older adult clients, and the focus of the present study was to examine the extent to which psychologists are prepared to work competently with older adult clients. Survey data were collected from 156 APA Division 12 (Clinical Psychology) and 17 (Counseling Psychology) members regarding the degree to which they engaged in each of 50 behaviors and the degree to which they considered each behavior ethical. Findings are presented in terms of percentages of responses to items on the questionnaire, and ANOVAs were performed on important demographic items to identify statistically significant differences among variables. Coursework in geropsychology or aging, specialization with older adults, and working with a high percentage of older adults were related to higher scores on the Overall Ethical Behavior scale. Females scored higher than males on the Overall Ethical Belief scale.

Disposable Time and Disposable Income: Problem Casino Gambling Behavior in Older Adults

Increasing numbers of retirees spend their leisure time in the ever-growing number of gambling casinos in this country. For most older adults, casino gambling is a new form of excitement and entertainment. However, for some retirees, especially those vulnerable to depression from the changes and losses that can occur in aging, casino gambling can become disordered, problematic, and/or an addiction. Although prevalence studies have examined the incidence of problem gambling in other age groups, little attention has been directed to the impact of casino gambling on older adults. The authors discuss problem and pathological gambling in retired older adults, and provide clinical case examples of a growing number of older adults with problem gambling behaviors seen in an outpatient geriatric psychiatry clinic. Finally, they urge that an evaluation of gambling behaviors be a routine portion of geriatric clinical evaluations.     

The Development of Sustained Attention in Children: The Effect of Age and Task Load

This study explored how children's sustained attention develops and the effect of manipulating task parameters on sustained attention. The sample comprised 57 children (5–12 years) who completed CogState and Score! (Test of Everyday Attention for Children). Novel variability and traditional indices indicated rapid development from 5–6 to 8–9 years on all measures and a developmental plateau from 8–9 to 11–12, with growth evident on some measures. Findings suggest that sustained attention improves to age 10, then plateaus with only minor improvements. Further, performance was generally poorer on high load tasks compared to low load, with the same developmental pattern uncovered.     

Perceptions of Responsibility and Mental Health Help-Seeking Among Psychologically Distressed Older Adults

This study explored the perceptions of responsibility for the cause and the solution of problems and the models of helping (or helping orientations) characterizing a sample of 319 community-dwelling, psychologically distressed older adults. All participants were referred for psychotherapy and had either accepted or rejected their referrals. We investigated whether the models distinguished acceptors and rejecters of psychotherapy referrals and whether they were differentially associated with help-seeking from nontherapist helpers. Results indicated that the preponderance of respondents subscribed to the moral and compensatory models. The compensatory model was associated with rejection of referrals, whereas the moral model was associated with increased help-seeking both from mental health professionals and from other formal and informal helpers. Implications of the findings for promoting older adults' utilization of mental health services are discussed.     

Review of Social Cognition Research on Stereotyping: Application to Psychologists Working with Older Adults

This paper summarizes a number of cognitive processes that contribute to the formation and maintenance of stereotypes. Specific discussion centers on how these may play a role in shaping perceptions of older adults. Suggestions are offered as to how psychologists might combat their tendency to stereotype because older adults have special needs that must be identified to provide accurate case conceptualization and effective psychotherapy from a professional ethics perspective.
