Chapter 8: “Always Green and Full of Sap”: Facilitating Wholeness in Aging

SUMMARY

Wholeness in aging is difficult to define, especially in the face of physical disability or catastrophic illness. How one meets the challenges of aging depends upon numerous physical, emotional, and spiritual factors. Rehabilitation may play an important role in restoring wholeness to those with physical disabilities. Likewise, a physical fitness program may lessen some of the effects of aging, helping the older person maintain a higher quality of life. The lived theologies of the older patients and their caregivers also interact, providing an important ground of connection in rediscovery of wholeness as well. Ultimately, our most important role as healthcare providers is to help our older patients regain and maintain this multidimensional wholeness even in times of physical challenge.     

心理负荷的评估:基于神经人因学的视角

心理负荷的评估正经历着从传统工效学向神经人因学的变革.EEG、ERPs、fMRI、fNIRS和TCD等神经科学研究技术为这场变革提供了有力的工具.研究发现:在单任务情境下,随着操作者心理负荷的增加,脑电α波活动减弱,θ波活动增强,并且前额皮层血流、左侧额下回血液氧合血红蛋白浓度变化均增加,大脑动脉血流速度也增快;在双任务情境下,随着操作者主任务心理负荷的增加,次任务的N1、新异P3和P3b等ERPs成分波幅降低.依据这些研究成果,学者们利用人工神经网络、支持向量机等模式分类算法实现了对心理负荷的实时在线评估.但是,各种研究技术在敏感性、诊断力、主任务干扰、实施需求、可接受性和信度等方面各有优势与不足.在未来研究中,要注意促进相关技术的融合、提高其可接受性,并充分利用模式识别算法提高其诊断力和敏感性.     

Perceived stress and everyday memory complaints among older adult women

Abstract

Memory complaints among older adults are often influenced by depression and anxiety, but the association of stress to memory complaints has received little attention. We examined the associations of perceived stress, life events, and activity level to everyday memory complaints among healthy older women, while controlling for the influence of depression and anxiety. Participants (N=54) completed self-report questionnaires on memory complaints, perceived stress, recent life events, activity level, depression, and anxiety. Partial correlation analyses indicated that higher levels of perceived stress were associated with higher levels of memory complaints when controlling for the influence of depression and anxiety, but that life events and activity level were not related to memory complaints. This study highlights that perceived stress, like depression and anxiety, is a psychological factor that influences the appraisal of cognitive ability; however, larger and more heterogeneous samples will be needed to better understand the multifactorial nature of memory complaints in older adulthood.     

Exercise type relates to inhibitory and error processing functions in older adults

ABSTRACT

This study investigated the association between exercise type and inhibition of prepotent responses and error detection. Totally, 75 adults (M = 68.88 years) were classified into one of three exercise groups: those who were regular participants in open- or closed-skill forms of exercise, and those who exercised only irregularly. The participants completed a Stroop and task-switching tasks with event-related brain potentials (ERPs) recorded. The results revealed that regular exercisers displayed faster reaction times (RTs) in the Stroop task compared with irregular exercisers. The open-skill exercisers exhibited smaller N200 and larger P300a amplitudes in the Stroop task compared with irregular exercisers. Furthermore, the open-skill exercisers showed a tendency of shorter error-related negativity latencies at the task-witching test. The findings suggest that older adults may gain extra cognitive benefits in areas such as inhibition functioning and error processing from participating in open-skill forms of physical exercises.     

Activity experiences shape perceived fitness trajectories: Results from a 6-month randomized controlled trial in older women

ABSTRACT

In this study we addressed the subjective benefits of activity interventions that were designed to improve cognitive fitness in old age. Two hundred and fifty-nine women (aged 70–93 years) were randomized to participate in an exercise or a computer course or a control condition for 6 months. Subjective ratings of the perceived change of cognitive and physical fitness components were captured before, during, after the intervention interval, and at a 10-month follow-up. Positive and negative affect levels and objective cognitive fitness parameters served as possible covariates. Multilevel modeling revealed that the computer group rated memory and concentration as having improved at 4 months and again at 6 months. The exercise group, in contrast, perceived physical capacities as maintained or improved. The characteristics of the activity experience seem to determine the perceived fitness changes. We conclude that actual learning experiences improve one's self-concept of abilities.     

不同年级学生自然阅读过程信息加工活动特点研究

探讨不同年级学生自然阅读过程的信息加工活动特点,包括两个实验。实验１结果表明,低年级学生自然阅读后再复述文章时需要重读原文的时间比高年级学生要多,据此初步推知,低年级学生自然阅读过程可能主要是单一的语言解码信息加工活动,高年级学生自然阅读过程可能同时进行了语言解码与组织连贯的信息加工活动,以后者为主。实验２比较不同年级的学生在自然阅读、理解任务阅读与记忆任务阅读三种情况下对文章信息保持的效果,结果

Meaningful patterns of activity amongst the long‐term inner city unemployed: a qualitative study

A number of studies have sought to establish the social psychological factors involved in the maintenance of active lifestyles during long‐term unemployment. The aim of this study was to describe and account for the development and maintenance of different patterns of activity, with reference to their perceived meaningfulness. This was undertaken with a sample of Birmingham's inner city, long‐term unemployed population recruited from three inner city Jobcentres, including men and women, and White, Asian and African Caribbean participants (N = 24). Interviews were conducted using a semi‐structured interview guide. Using the qualitative software program, NUD.IST, the data were analysed according to the principles of the grounded theory approach. Activities were characterized as: domestic; educational; work‐like; socializing; and none. A model of meaningful activity in the context of formal unemployment was developed. The main components of the model were: features of formal employment that inhibited participants' engagement in it; the requirements for personal meaningful activity (challenging activity, effort and commitment, and being valued by others); the consequences of meaningful activity (opportunities for self‐determination and self‐development, and achievement, competence, and confidence) and consolidating factors (social comparison, self‐appraisal, religious and political beliefs, and social support). Theories of unemployment of Jahoda, Warr, and Fryer are considered in the light of the present findings. Copyright © 2002 John Wiley & Sons, Ltd.     

Smart and easy: Co-occurring activation of spontaneous trait inferences and spontaneous situational inferences

Social perceivers have been shown to draw spontaneous trait inferences (STI’s) about the behavior of an actor as well as spontaneous situational inferences (SSI’s) about the situation the actor is in. In two studies, we examined inferences about behaviors that allow for both an STI and an SSI. In Experiment 1, using a probe recognition paradigm, we found activation of both STI’s and SSI’s. In Experiment 2, using a relearning paradigm, we again found activation of both STI’s and SSI’s, regardless of temporarily activated processing goals. Results are discussed in light of three-stage models of the process of social inference.     

Executive functioning profiles in elite volleyball athletes: Preliminary results by a sport-specific task switching protocol

Executive functions (EF) are crucial for the athletes’ success, and they are even more essential in open skill sports (e.g. volleyball and football). In these sports, due to continuously changing conditions, goal-directed behaviours need to be repeatedly adjusted and corrected. One of the most important EF is the ability to continuously switch between two different tasks being required in a random sequence. We used a task-switching protocol in elite volleyball athletes, usually playing different roles, with the aim of evaluating if each role is characterized by specific switching abilities. On the basis of the specific competences requested by the game, thirty-six elite volleyball athletes were assigned to three groups: Strikers, Defenders and Mixed. Each player completed a customized sport-specific task-switching paradigm. Data evidenced that each role has specific characteristics. In Reaction Times, the Strikers were the fastest to answer to stimuli, while the Defender group provided a worse performance, particularly when defensive actions, that probably require more cognitive elaboration, had to be processed. Different effects emerged by the Errors. In fact, the Mixed group, which was the one with more expertise, appeared to be more accurate in the responses.Although preliminary, these results showed a minimal degree of cognitive flexibility for highly specialized Strikers and a maximum level for Mixed, allowing thus to highlight specific profiles of athletes. Data observed indicate the possibility to develop a test assessing the executive domain during the recruitment in a team, revealing a useful tool for choosing the most suitable role.
