Individual values and well-being: The moderating role of personality traits

This study examined the role of values, traits and their interactions for the experience of eudaimonic and hedonic well-being. First wave studies on value and well-being relationships yielded inconsistent results suggesting that these relationships are moderated by other factors, possibly by personality traits. We asked a representative sample of adult Poles (N = 1161) to report on their personality traits (according to five-factor theory), values (conceptualised by Schwartz) and well-being (hedonic and eudaimonic). Results showed, that higher Extraversion, Emotional stability, Intellect, Agreeableness and Conscientiousness were related to higher well-being, confirming and expanding claims from personality theory of subjective well-being: stable predispositions are related not only to subjective, but also to eudaimonic well-being. Values expressing Openness to change, Self-transcendence and Conservation were also positively correlated with well-being, while the role of Self-enhancement was unclear. This confirmed that growth needs expressed in Openness to change and Self-transcendence values promote well-being, but also that values expressing deficiency needs can be positively related to well-being, possibly in specific circumstances. Finally, the two levels of personality (traits and values) proved to have a joint relationship to well-being: higher Conscientiousness and Agreeableness enhanced positive relationships of Openness to change and Self-transcendence with some aspects of well-being.     

A coordinated analysis of the associations among personality traits,cognitive decline,and dementia in older adulthood

There are individual differences in the rates of cognitive decline across later adulthood. Personality traits are among the factors that may account for these differences. The current project investigated whether personality traits were associated with trajectories of cognitive decline, and whether the associations were different before and after dementia diagnosis. The data was analyzed using linear mixed effects regression. Across study aims is a focus on replicability and generalizability. Each question was addressed in four independent longitudinal studies (EAS, MAP, ROS, SATSA), then meta-analyzed, providing estimates of replicability. Results indicated that low neuroticism and high openness were associated with total cognitive function. We detected evidence for cognitive decline in all four samples, and openness was associated with decline post dementia diagnosis.     

The relationship between mental toughness and subjective mental illness recovery

Recently there has been an increasing interest in subjective mental illness recovery, and it has been recognised that there is an important role for characteristics such as self-efficacy and locus of control. Mental toughness describes a set of characteristics important for dealing with stress and pressure, and is comprised of challenge, commitment, control of emotion, control of life, confidence in abilities, and interpersonal confidence. The current study explored relationships between mental toughness and subjective mental illness recovery. Seventy-seven participants (nineteen males and fifty-eight females, the majority of which were young adults aged 18–21 years) who had previously recovered from, or were currently recovering from a mental illness (self-reported) completed questionnaire measures of mental toughness and subjective mental illness recovery. Mental toughness had a positive significant relationship to recovery, with particular roles for commitment and confidence in abilities. The findings are discussed in terms of implications for recovery-oriented practice, intervention, and measurement. Further research should examine the role of mental toughness in different aspects of subjective recovery, and also explore relationships with objective measures of recovery.     

Direct social perception of others’ subjective time

In this paper, I deploy Gallagher et al.’s theory of Direct Social Perception (DSP) to help explain how we perceive others’ subjective time. This process of second-person temporal perception plays an important role in interpersonal interaction, yet is often glossed over in discussions of intersubjectivity. Using A.D. Craig (2009) ‘awareness’ model of subjective time to unify converging evidence that subjective time is embodied, affective, and situated, I argue that subjective time cannot be considered as a hidden or invisible aspect of a private mind, but is partially externally visible through our gestures, expressions, and other behaviours as they unfold within a particular context. My central thesis is that, in face to face interactions, we are able to directly perceive these visible components of other people’s subjective time. This is made possible by our “enculturated” (Menary, 2015) and enactive perceptual faculties. The process of social perception is not a passive, unidirectional affair where static information about one person’s subjective time is transmitted to the other, but rather inextricably linked with action (both at the personal and subpersonal level) and interaction effects produced by a dynamic coupling between participants. Such an enactive perspective reveals how others’ subjective time can be perceived in everyday interactions.     

Stress and subjective life expectancy: Cross-sectional and longitudinal associations in early adolescence

Using data from a longitudinal study, the present study employed a latent class mover-stayer analytical strategy to examine both the cross-sectional and longitudinal (+33 months) relationship between membership of stress classes, and subjective life expectancy. Participants were from 21 High schools in Scotland and Northern Ireland. Data were collected in the first year of High school (mean age = 12.5 years), and at +33 months (fourth year, or school year 11). Sample 1 consisted of 1171 adolescents (40.82% females, 2.56% unreported) in Northern Ireland. Sample 2 consisted of 1059 adolescents (52.79% females, 1.32% unreported) in Scotland. Adolescents with the lowest levels of stress projected the highest subjective life expectancy scores. Longitudinal analyses were jumbled and not in keeping with cross-sectional results. More research may be needed on the trajectory of subjective life expectancy over time before it can be depended upon as a reliable outcome variable in adolescent development.     

Aging Affects the Ability to Process the Optic Flow Stimulations: A Functional Near-Infrared Spectrometry Study

Abstract

Optic flow (OF) has been utilized to investigate the sensory integration of visual stimuli during postural control. It is little known how the OF speed affects the aging brain during the sensory integration process of postural control. This study was to examine the effect of OF speeds on the brain activation using functional near-infrared spectroscopy (fNIRS) and postural sway between younger and older adults. Eleven healthy younger adults (5M/6F, age 22?±?1-year-old) and ten healthy older adults (4M/6F, age 71?±?5-year-old) participated in this study. A virtual reality headset was used to provide the OF stimulus at different speeds. A forceplate was used to record the center-of-pressure to compute the amplitude of postural sway (peak-to-peak). Compared with younger adults, older adults showed significantly increased activation in the OF speed of 10?m/s and decreased activation in the OF speed of 20?m/s in the left dorsolateral prefrontal cortex. Older adults also showed decreased activation in the left temporoparietal region (VEST) in the OF speed of 20?m/s. A significant difference in peak-to-peak was found between groups. Our results indicated that age might be associated with the ability to process fast OF stimulation.     

Authenticity and subjective well-being: The mediating role of mindfulness

Authenticity is generally indicated to be an important predictor to subjective well-being. However, remarkably few empirical researches investigated possible psychological mechanism underlying the process. The purpose of the current research is to explore whether mindfulness can explain one pathway between authenticity and subjective well-being. By conducting a cross-sectional study and a time-lagged study, we verified that higher authenticity associated higher subjective well-being via higher mindfulness. Furthermore, the effect of authenticity on subjective well-being was specifically through two facets of mindfulness–describing and acting-with-awareness. These results contribute to a better understanding of the association of authenticity and subjective well-being. Moreover, these findings suggest that mindfulness training may be a useful technique to accelerate the transformation from being thyself to being happy.     

年老化对中文阅读眼动控制的影响:来自词长和语境预测性效应的证据

本研究通过对比老年与青年人在阅读中词长、词频和语境预测性效应上的差异,探讨中文阅读中眼动控制的年老化问题。结果发现:(1)词长的年龄主效应显著,注视时间和首次注视位置指标上年龄与词长的交互作用显著;(2)在注视时间指标上发现了显著的词频和语境预测性效应,年龄与语境预测性之间交互作用显著。综合而言,中文阅读中老年读者的词长效应和语境预测性效应不同于青年读者,由此可见,视觉功能和词汇加工功能衰退都是中文阅读眼动控制年老化的诱发原因。     

A gist orientation before retrieval impacts the objective content but not the subjective experience of episodic memory

A gist retrieval-orientation decreases one’s ability to remember objective details from past experiences. Here, we examined whether a gist retrieval-orientation manipulation can impact both the objective and subjective aspects of remembering. Young participants took part in two cued-recollection tasks in which they studied pictures associated with labels; at retrieval, from the labels, they evaluated the vividness of their memories of the corresponding pictures, and recalled picture details. Before retrieval, participants were submitted either to a gist or a control retrieval-orientation (one per task). Results revealed that the amount of recalled details was lower following the gist condition while vividness ratings did not differ between the two retrieval orientations. Critically, the amount of recalled details predicted the corresponding vividness ratings to a similar extent in the gist and control conditions, thus suggesting that recollected memory traces in the gist condition were still rich enough to be judged as subjectively vivid.     

The impact of cognitive functioning on driving performance of older persons in comparison to younger age groups: A systematic review

Older drivers are at a severely higher risk for motor vehicle crash involvement. Due to the global aging of the population, this increased crash risk has a significant impact on society, as well as on an older individual’s quality of life. For this reason, there is a need for understanding how normal age-related changes in cognition and underlying brain dynamics impact driving performance to identify the functional and neurophysiological biomarkers that could be used to design strategies to preserve or improve safe driving behavior in older persons. This review provides an overview of the literature on age-related changes in cognitive functioning and brain dynamics that impact driving simulator performance of healthy persons. A systematic literature search spanning the last ten years was conducted, resulting in 22 eligible studies. Results indicated that various aspects of cognition, most importantly executive function, complex attention, and dual tasking, were associated with driving performance, irrespective of age. However, there was a distinct age-related decline in cognitive and driving performance. Older persons had a more variable, less consistent driving simulator performance, such as more variable speed adaptation or less consistent lane keeping behavior. Only a limited number of studies evaluated the underlying brain dynamics in driving performance. Therefore, future studies should focus on implementing neuroimaging techniques to further unravel the neural correlates of driving performance.
