Correlation between functional mobility and cognitive performance in older adults with cognitive impairment

Association between cognitive impairment and gait performance occurs in mild cognitive impairment (MCI) and Alzheimer‘s disease (AD), particularly under “divided attention” conditions, leading to a greater risk of falls. We studied 36 controls, 42 MCI, and 26 mild AD patients, using the Timed Up-and-Go test (TUG) under four conditions: TUG single – TUG1; TUG cognitive – TUG2; TUG manual –TUG3; TUG cognitive and manual – TUG4. Cognition was assessed using the MMSE, SKT, Exit25, and TMT (A and B). We found significant correlations between cognitive scores and TUG2 [r values (MMSE: –0.383, TMT-A: 0.430, TMT-B: 0.386, Exit25: 0.455, SKT: 0.563)] and TUG4 [(MMSE: –0.398, TMT-A: 0.384, TMT-B: 0.352,Exit25: 0.466, SKT: 0.525)] in the AD group, and between all TUG modalities and SKT in MCI and AD. Our results revealed that functional mobility impairment in cognitive dual tasks correlated to cognitive decline in AD patients and to attention and memory impairment in MCI.     

Autistic features in the general population: Implications for sensing purpose in life

Purpose in life has been discussed as a psychosocial process in which individuals construct their life aims in relation to other people. Consequently, difficulty attending to social cues could limit the extent to which individuals feel purposeful. The present study (N = 252) examined links between subclinical autistic features found in the general population and perceived purpose in life. Results showed that autistic features were negatively associated with purpose even after accounting for age, gender, positive mood, and dispositions in Big 5 personality traits. Findings are discussed in terms of directions for future research aimed at elucidating the mechanisms that may explain the observed associations. In completing this study, it is hoped that the present findings can be utilized as groundwork for the investigation of psychosocial development in special populations.     

A Self‐Determination Approach to Understanding Individual Values as an Interaction Condition on Employees' Innovative Work Behavior in the High‐Tech Industry

Drawing on self‐determination theory (SDT; E.L. Deci & R.M. Ryan, 1985, 2000) and using corporate samples (N = 284; 63% Male; Mean Age = 34, SD = 6.09) from high‐tech firms in China, this empirical study explored the path model from satisfaction of the basic psychological needs for autonomy, competence, and relatedness, through autonomous motivation to employees' innovative work behavior (“IWB”; J. De Jong & D. Den Hartog, 2010). It also simultaneously examined the interactions between autonomous work motivation and individual values (collectivism, H.C. Triandis (1995); uncertainty avoidance, R. J. House, P. J. Hanges, M. Javidan, P. W. Dorfman, & V. Gupta (2004); and power distance, J. Farh, R.D. Hackett, & J. Liang (2007)) in the conditioned path model. The regression results obtained from conditional PROCESS analysis (A.F. Hayes, 2013, 2018) suggest that basic psychological needs satisfaction is positively related to employees' IWB via autonomous motivation, but that these indirect effects were weaker when employees' power distance value orientation was high. Implications, limitations, and future research directions are discussed.     

童年贫困与晚年认知老化：加速还是延缓?

童年贫困与晚年认知老化的关系尚存争议。有的研究表明, 童年贫困会加速个体的认知老化, 但是也有研究发现童年贫困会延缓个体的认知老化, 这与社会流动性起到的调节作用有关。对于童年贫困个体, 低稳定或者社会经济地位的向下流动(即长期贫困)会使逆境产生的消极影响不断累积, 从而加速个体的认知老化; 而心理韧性高的童年贫困个体, 可能会促使社会经济地位向上流动, 这会增加个体的认知储备, 并提升特定认知能力, 进而延缓认知老化。今后该领域的研究应该探讨童年主观贫困与认知老化之间的关系以及童年贫困对不同认知能力老化的影响, 也应关注童年贫困与晚年认知老化关系研究中的幸存者偏差效应。     

累积情境风险与流动儿童主观幸福感的关系:个体保护因子的补偿效应和保护效应

对511名初二年级的流动儿童（平均年龄：14.37±0.78岁）及其家长进行问卷调查,考察累积情境风险与流动儿童主观幸福感的关系,及自尊、心理弹性和情绪调节等个体保护因子的作用方式差异及累积效应。结果发现：（1）累积情境风险负向预测流动儿童主观幸福感,各领域风险预测作用由大到小依次是家庭关系风险、同伴风险和学校风险,家庭社会经济地位风险预测作用不显著;（2）自尊在各领域风险与主观幸福感的关系中均发挥补偿效应;心理弹性在同伴、学校领域风险中发挥补偿效应,在家庭关系领域风险中发挥保护效应;情绪调节仅在同伴领域风险中发挥保护效应;（3）个体面临的风险数越多,具备的保护因子数越少,流动儿童主观幸福感越低。     

Me,Myself, and Mobility: The Relevance of Region for Young Adults' Identity Development

As residential mobility is a common life event that particularly affects young adults, regional identity may be relevant for young adults. We therefore extended the three‐dimensional identity model to the regional domain. The development of regional identity was studied using a prospective design over six months with a sample of 1,795 post‐secondary graduates (71% female, mean age of 24.54 years), containing both movers and non‐movers. Latent profile analyses and latent profile transition analyses revealed three main findings: First, solutions with four regional identity statuses—moratorium, searching moratorium, closure, and achievement—were found to be most interpretable. Second, the emergent statuses differed substantially in terms of Big Five personality traits and life satisfaction, as well as with moving experience. Third, the stability of identity status membership across a period of six months was highest for the non‐movers group. Comparatively less stability across time was found for the movers, underscoring the relevance of transitions for identity development. Taken together, these findings show that even in a mobile world, region matters in identity development. Copyright © 2016 European Association of Personality Psychology     

Process Overlap Theory: A Unified Account of the General Factor of Intelligence

The most replicated result in the field of intelligence is the positive manifold, which refers to an all-positive pattern of correlations among diverse cognitive tests. The positive manifold is typically described by a general factor, or g. In turn, g is often identified as general intelligence, yet this explanation is contradicted by a number of results. Here we offer a new account of g: process overlap theory. According to the theory, cognitive tests tap domain-general executive processes, identified primarily in research on working memory, as well as more domain-specific processes. Executive processes are tapped in an overlapping manner across cognitive tests such that they are required more often than domain-specific ones. The theory provides an account of a number of findings on human intelligence. As well, it is formalized as a multidimensional item response model and as a structural model, and the neural mechanisms underlying the proposed overlapping processes are discussed.     

Decision-related action orientation predicts police officers' shooting performance under pressure

Background and Objectives: We aimed to test whether police officers’ trait self-control strength decreases negative effects of high pressure (HP) on state anxiety, shooting behavior, and shooting performance. Design and Methods: Forty-two officers performed a shooting test under both high and low-pressure (LP) conditions. Self-control strength was assessed with the decision-related action orientation (AOD) scale of the Action Control Scale (ACS-90). Effects of AOD on perceived anxiety, heart rate, shooting time, and shot accuracy were estimated and controlled for those of other individual difference measures (i.e. age, police working experience, trait anxiety, and threat-related action orientation). Results: After controlling for baseline values in the LP condition as well as the other individual difference measures, AOD significantly predicted shot accuracy in the HP condition. Conclusions: Results suggest that trait self-control strength in the form of AOD helps officers cope with anxiety and maintain perceptual-motor performance under HP.     

Trait predictors of placebo responses in itch

This study investigated trait predictors of placebo responses in the context of inflammatory skin reactions. This was a randomized, cross-over, experimental study using a deceptive placebo protocol. A healthy sample of volunteers (N = 48) completed online personality measures, then attended two laboratory sessions in which short-term inflammatory skin reactions were induced. One was a control session and the other the ‘treatment’ session in which a placebo cream was administered with the suggestion of a reduced skin reaction. A placebo response was defined as smaller skin reactions in control vs. treatment sessions. The traits ego resiliency and neuroticism were selected as possible predictors of placebo responses. Traits were selected in consideration of the two-faceted transactional model of placebo responsiveness and in light of empirical and psychometric considerations ego resiliency emerged as a consistent predictor of placebo responses in itch (p < .05). This is the first study to identify trait predictors of placebo responses in inflammatory skin reactions. Ego resiliency may typify greater placebo responsiveness; however, this may only be in certain contexts. Matching treatment approaches to bio-behavioural response tendencies may be useful clinically if the placebo component of traditional treatments can be enhanced.     

Facilitators,barriers and needs in the use of adaptive driving strategies to enhance older drivers’ mobility: Importance of openness,perceptions, knowledge and support

This study aimed to explore facilitators, barriers and needs for the use of adaptive driving strategies (i.e., means used to adjust driving for diminished abilities) which can optimize the community mobility of older drivers. An exploratory qualitative clinical research design was conducted with 11 older drivers, 7 relatives and 14 driving professionals. Five focus group discussions were audio recorded, transcribed and analyzed. Facilitators for the use of adaptive driving strategies were: being a woman; perceiving dangers; recognizing the usefulness of strategies and abilities as diminished; having disabilities or discomfort when driving; experiencing complex driving situations; receiving help of relatives and services of professionals; and having other transportation options. Barriers were: not knowing strategies; being proud; lack of self-criticism; unwillingness of relatives and physicians to intervene; having costs to the use of adaptive strategies; recognizing driving as important; perceiving the complexity of using other transportation options; and lack of proximity to facilities and services. To foster the use of adaptive strategies, TV, radio, newspapers and information sessions need increasing older drivers’ awareness about the age-related changes, the community resources, and the strategies themselves, including their importance in safe driving. Furthermore, to support older drivers in changing their driving habits and using adaptive strategies, results demonstrated that it is important to involve their relatives and professionals. While promoting safe driving and the prevention of collisions and injuries on the road, knowledge about facilitators, barriers and needs for the use of adaptive driving strategies could ultimately allow seniors to optimize their community mobility.
