工作记忆中的积极效应：情绪效价与任务相关性的影响

积极效应指相比于年轻人, 老年人更倾向于优先加工积极情绪刺激而非消极情绪刺激。近年来工作记忆的研究发现积极效应会受到情绪效价与任务相关性的影响：情绪效价作为任务相关属性的研究支持工作记忆中存在积极效应, 具体表现为老年人对积极情绪刺激记忆的增强, 以及对消极情绪刺激记忆的减弱; 情绪效价作为工作记忆任务无关属性的研究相对较少, 且未发现一致的积极效应, 提示情绪效价及任务相关性均为影响工作记忆积极效应的关键因素。脑成像的研究初步表明, 工作记忆中情绪加工上的年龄效应与背侧执行系统和腹侧情绪系统的随龄功能变化有关。社会情绪选择理论与双竞争模型对工作记忆中的积极效应具备较大的解释力, 而动态整合理论尚缺乏实证研究支持。未来研究可进一步探究老年人工作记忆不同阶段情绪加工的特点, 澄清不同情绪材料内在编码过程上的差异对积极效应发生机制的潜在影响, 探讨情绪效价及任务相关性影响工作记忆积极效应的关键神经环路, 并揭示情绪工作记忆训练提升老年人认知功能与情绪体验的内在机制及其潜在应用价值。     

The roles of chronological age and time perspective in memory positivity

The observation that older adults show enhanced cognition for emotionally positive information has been labeled the positivity effect (Reed, Chan, & Mikels, 2014). According to the Socioemotional Selectivity Theory (SST, Carstensen, 1991), a prominent lifespan development theory, cognition is strongly influenced by motivational goals, and these goals are impacted by subjective time perspective. Although the positivity effect is most commonly observed in older adults, as age usually co-varies with time perspective, the SST posits that time perspective, not age, is the key explanatory factor of positivity. We examined the effects of these predictors on positivity in an episodic memory task in younger and older adults and found that age, not time perspective, was a key predictor of memory positivity. Our results add to the growing literature that challenge the notion that time perspective is the driving force behind age-related differences in emotional processing and functioning.     

Feeling good and functioning well: distinctive concepts in ancient philosophy and contemporary science

This paper is an invited response to Kashdan, Biswas-Diener, & King (2008) and to Waterman's (2008) commentary. Kashdan et al. assert that the distinction between hedonic and eudaimonic well-being is unwarranted philosophically and scientifically. We disagree, because a correct understanding of Aristotle refutes Kashdan et al.'s claims, and we refute three specific claims made about the definition, measurements, and overlap of kinds of subjective well-being. We re-analyze data from Keyes' (2005b) paper on mental health, and find that nearly half (48.5%) of the MIDUS national sample has high hedonic well-being. However, only 18% are flourishing, which requires a high level of hedonic and eudaimonic well-being. The remaining 30.5% with high hedonic well-being but moderate eudaimonic well-being has nearly twice the rate of mental illness as flourishing individuals. Costs are incurred, we conclude, by science and citizens when we do not distinguish and achieve both kinds of well-being.     

Pathways to flourishing among pharmacy students: The role of study demands and lecturer support

This study investigated possible pathways to flourishing among pharmacy students attending a South African university (N = 799; females = 81.6%; Afrikaans-speakers = 84.7%, mean age = 20.42 years, SD = 2.25 years). The students completed the Mental Health Continuum – Short Form (MHC-SF) and an Overload and Lecturer Support Survey. Of the 779 pharmacy students, 40.3% self-reported as flourishing, with high mean scores on workload and lecturer support. The level of emotional well-being of year group 2 was the highest. Following structural equation modelling, overload and lecturer support explained between 18% and 31% of the variance in the flourishing of the different year groups. From the second to the third year, the predictive value of overload and lecturer support for flourishing decreased by 8.8%. Lecturer support and low overload appear to play a positive role in the flourishing of higher education students.     

Examining methodological variation in response inhibition: The effects of outcome measures and task characteristics on age-related differences

This study addressed methodological issues common to developmental studies on response inhibition. Age-related differences were investigated using two Stroop-like tasks with different levels of complexity and comparing different outcome measures in a sample of 340 children and adolescents aged 7–15 years. First, speed and accuracy of task performance were examined; the results showing that improvement in speed continued until age 13 in both the basic naming task and the two inhibition tasks. Improvement in accuracy was less consistent and continued until age 9 or 13 years. Second, two different algorithms were employed to control for the effects of basic processes in inhibition tasks. The difference algorithm indicated age-related differences similar to those for speed. The ratio algorithm, however, suggested earlier deceleration of development of response inhibition at 9 or 11 years of age. Factors related to the cognitive requirements and presented stimuli also had an effect on the results. The present findings shed light on the inconsistencies in the developmental studies of response inhibition and demonstrated that the selection of outcome measures and task characteristics are critical because they affect the way development is depicted.     

Forgiveness and Health: Age Differences in a U.S. Probability Sample

Forgiveness is a variable closely related to religiousness and spirituality that has been hypothesized to be protective of mental and physical health. However, we do not clearly understand which aspects of forgiveness are most clearly associated with health outcomes, and the conditions under which these relationships occur. This study used national probability data to systematically examine age differences in the association between forgiveness, religiousness/ spirituality, and respondent reports of mental and physical health. Results showed age differences in the levels of forgiveness of others and feeling forgiven by God. In both cases, middle and old age adults showed higher levels of these forms of forgiveness than young adults. Furthermore, the relationship between forgiveness of others and respondent reports of mental and physical health varies by age. Forgiveness of others was more strongly related to self-reported mental and physical health for middle and old age adults than for young adults.     

The role of the arts and humanities in human flourishing: A conceptual model

There is much debate on the value of the arts and humanities in our society. Each side provides strong arguments, but there has been little empirical research to draw on. A key reason for the lack of scientific evidence is the absence of a conceptual model on which to base investigations of the ways the arts and the humanities might contribute to human flourishing. To address this, we present a model to demarcate the domain of the arts and humanities by means of an extensional definition (e.g. majors, disciplines, and occupations) integrated with a functional analysis (i.e. modes of engagement and activities of involvement). We suggest immersion, embeddedness, socialisation, and reflectiveness as mechanisms by which the arts and humanities may enhance various forms of human flourishing. We conclude with implications of the model and ideas for future research to investigate the effects of the arts and humanities on human flourishing.     

Examining maternal age,breastfeeding self-efficacy and health locus of control in psychological wellbeing of mothers

We investigated the direct and interaction influence of maternal age, breastfeeding self-efficacy (BSE), health locus of control (HLOC) on six dimensions of psychological wellbeing of breastfeeding mothers in Lagos, Nigeria. Data were collected from a convenience sample of 291 mothers attending health facilities in two suburb local government areas. The survey included socio-demographics (maternal age, marital status, ethnicity, education level and position of the baby currently breastfeeding), breastfeeding self-efficacy, health locus of control and psychological wellbeing scales. Independent variables were tested against sense of autonomy, positive relations with others, purpose in life, self-acceptance, environmental mastery and personal growth using factorial Multivariate Analysis of Variance. Results showed direct influence of BSE, HLOC and maternal age on various dimensions of psychological wellbeing. Interaction influences indicate BSE and HLOC on environmental mastery; BSE and maternal age on self-acceptance and HLOC and maternal age on sense of autonomy, positive relationship with others and self-acceptance respectively. In conclusion, maternal age, breastfeeding self-efficacy and health locus of control are vital for mothers to enjoy plenty dimensions of psychological wellbeing. Breastfeeding mothers need to be confident in their abilities to breastfeed and have control over their health-related behaviour in order to enjoy sufficient dimensions of psychological wellbeing.     

注意与记忆中的“积极效应” ——“老化悖论”与社会情绪选择理论的视角

老年人在注意和记忆活动中存在着“积极效应”现象,即对积极材料的加工维持得较好,表现出对积极信息的偏向。社会情绪选择理论从时间的认知评估影响情绪目标的选择来解释这一现象。同时,研究发现信息的加工方式与“积极效应”有密切关联,当控制加工时,“积极效应”出现;而自动加工时,“积极效应”消失。“积极效应”受到时间认知的控制,也受到认知资源和认知能力的限制。目前,随着认知神经科学的发展,利用先进设备与仪器研究老年人认知活动中的“积极效应”有着广阔的前景     

The contextual role of subjective age in the chronological age/absenteeism relationship in blue and white collar teams

Organizations in the twenty-first century face the challenges of an increasingly ageing workforce, which have an effect on organizational health and productivity. As chronological age has shown to be an insufficient indicator of employees’ health and, in particular, absenteeism, we apply the subjective age concept (i.e., how old an employee feels) at the team-level to explain the average chronological age/average short-term absenteeism relationship. We develop a theoretical framework for underlying processes, combining the subjective age research with the socioemotional selectivity theory and team contagion processes. We test our predictions in a time-lagged team-level sample of 1,015 teams with 12,926 employees to find a significant interactive effect of average chronological age and average subjective age on average short-term absenteeism in teams. The relationship is negative and significant when average subjective age is low. Under high-average subjective age, the relationship is non-significant. Furthermore, this interactive effect (average chronological age/average subjective age) is moderated by job type (white versus blue collar) in the form of a three-way interaction, indicating that the effect is only significant among white collar teams. We hope to enrich the theoretical debate on age and absenteeism and provide organizations with a new perspective on ageing work teams.     

Human values priorities: effects of self-centredness and age

This study aims to assess the effects of the degree of self-centredness/selflessness and age on human values priorities according to Schwartz model. This model displays two main dimensions which oppose on one hand, self-enhancement to self-transcendence and on the other hand, openness to change to conservation. The sample consisted of 307 adults aged 18 to 65 who filled in two questionnaires: the Self-Transcendence Inventory (STI) and the Questionnaire of Values by Portraits (QVP). The results show that the more people were selfless, the more they gave greater importance to self-transcendence and less importance to self-enhancement; and inversely. Moreover, the older the participants were, the more they valorised collective values compared to individual values. Finally, age appeared as a more relevant predictor of values priorities than the degree of self-centredness. Such results could be of first importance in terms of designing moral education strategies.     

Positivity and the Construction of Life Satisfaction Judgments: Global Happiness is not the Sum of its Parts

The present study investigated how reports of satisfaction with specific versus global domains can be used to assess a disposition towards positivity in subjective well-being reports. College students from 41 societies (N = 7167) completed measures of life satisfaction and ratings of global and specific aspects of their lives. For example, participants rated satisfaction with their education (global) and satisfaction with their professors, textbooks, and lectures (specific). It was hypothesized that global measures would more strongly reflect individual differences in dispositional positivity, that is, a propensity to evaluate aspects of life in general as good. At both the individual and national levels, positivity predicted life satisfaction beyond objective measures. Also, positivity was associated with norms about ideal life satisfaction such that countries and individuals who highly valued positive emotions were more likely to display positivity. The difference between more global versus more concrete measures of satisfaction can be used as an indirect and subtle measure of positivity.     

Facial emotion recognition during pregnancy: Examining the effects of facial age and affect

It is vital that new mothers quickly and accurately recognize their child’s facial expressions. There is evidence that during pregnancy women develop enhanced processing of facial features associated with infancy and distress, as these cues signal vulnerability and are therefore biologically salient. In this study, 51 pregnant women at 17–36 weeks gestation watched neutral infant and adult faces gradually morph into either happy or sad expressions. We measured the speed and accuracy with which participants were able to recognize facial affect (happy vs. sad) across facial ages (infant vs. adult). Participants were faster and more accurate at recognizing happy versus sad faces and adult versus infant faces. We discuss how prior exposure to a certain face type may explain faster recognition. We also consider these results in the context of evidence indicating positive affect is recognized more quickly, but associated with slower attention and detection.     

Set points of positivity ratio for different levels of well‐being: A latent profile analysis

Previous studies have explored the set points of the positivity ratio by grouping according to predetermined cut‐off scores, resulting in inconsistent criteria and unstable results. This study intends to further explore the set points of the positivity ratio using latent profile analysis. Two samples of 716 college students and 381 adults in China completed the Questionnaire for Eudaimonic Well‐Being, the Personal Growth Subscale from Ryff's Psychological Well‐being Scale, the Need Satisfaction Questionnaire, and the Emotional Experience of Well‐Being Questionnaire. College students were classified into four classes (2.0, 2.8, 3.7 and 5.0) with the set points of the positivity ratio, whereas adults were classified into three classes (1.9, 2.9 and 4.2) with the set points of the positivity ratio. The difference of the set points between college students and adults was nonsignificant for medium and high well‐being classes, and significant with a small effect size for the higher well‐being class. Future research should examine more diverse samples and combine the real experience method to further explore the set points of the positivity ratio.     

Menopausal stage and age and perceptions of body image

Abstract

The aim of This study was to investigate the association between menopausal stage and age and women's perception of their body image. Females from a community sample (n = 304. age range from 35 to 65 years) volunteered to complete a structured questionnaire which contained the Multidimensional Body Self Relations Questionnaire (MBSRQ) and the Stunkard Body Shape Figure Scale. One hundred and twenty women were premenopausal, 76 women were perimenopausal and 108 were postmenopausal. The effects of age and menopausal stage could not be separated in ratings of appearance evaluation, fitness evaluation, current, ideal and societal ratings of the Stunkard Body Shape Figure Scale. Premenopausal women (who were likely to be younger) had more positive ratings of appearance evaluation and fitness evaluation than menopausal women (who were likely to be older). Women who were premenopausal nominated smaller figures from the Stunkard Body Shape Figure Scale for ratings of the current, ideal and societal body shape than women who were perimenopausal and postmenopausal. The implications of these findings as they relate to women as they progress through the menopausal transition and as they become older is discussed.     

Examining the relationship of perfectionism,depression, and optimism: Testing for mediation and moderation

The present study investigated the relationship between perfectionism and depression, and the mediation/moderation effects of optimism. Participants were126 adults (78% women, mean age = 27 years) who completed an online survey that included the Multidimensional Perfectionism Scale (Frost, Marten, Lahart, & Rosenblate, 1990), the Revised Life Orientation Test (Scheier, Carver, & Bridges, 1994), and the Hamilton Depression Inventory (Reynolds & Kobak, 1995). Maladaptive, adaptive and total perfectionism were examined in separate analyses. In most analyses, the data fit a mediation model. Optimism limited the effect (relationship) of total and maladaptive perfectionism on depression. Adaptive perfectionism was related to depression only through optimism. There was a small gender difference, with indirect effects greater for men. These results are consistent with past research and support the notion that correlations between perfectionism, as a trait, and affective variables must be examined using multivariate models that allow for the determination of complex relationships.     

Health performance of individuals within the Campbell paradigm

In this paper, we developed a comprehensive health performance measure that formally links individual health attitudes with the likelihood of engaging in a wide variety of health‐related behaviours from various domains such as sustenance, hygiene, and physical exercise. Within what Kaiser, Byrka, and Hartig (2010) call the Campbell paradigm, we equated general health attitude with what a person does to retain or promote his or her health. Thus, health behaviours, on one hand, were expected to form a homogeneous, transitively ordered class of behaviours. On the other hand, the very behavioural class was in turn thought to be the basis from which an individual's health attitude could be directly assessed. A sample of 391 adults provided us with survey data containing different sets of health behaviours as well as variables and personality measures that had been corroborated as health‐behaviour relevant in previous research. We found that self‐reports of 50 behaviours and expressions of appreciation for 20 of these behaviours from various domains formed a transitively ordered class of activities. In contrast to the conventional view in health psychology, in which attitudes are regarded as a psychological cause behind individual behaviour, and in contrast to conventional findings in health psychology, where behaviours appear to fall into numerous sets of more or less distinct domains of health‐enhancing activities (e.g., exercising or avoiding risks), our findings speak of the psychological and formal unity of health behaviour. Inevitably, attitude measures grounded in the Campbell paradigm gauge individual attitudes, and just as much, they measure the health performance of individuals.     

Seeking help when transgender: Exploring the difference in mental and physical health seeking behaviors between transgender and cisgender individuals in Ireland

Abstract

Background: While there is growing awareness of the need to support the physical and mental wellbeing of transgender people, some may be reluctant to seek help from healthcare professionals. Little is understood about the mechanisms that influence help-seeking behavior in this group.

Aims: This study aimed to compare transgender and cisgender participants in their likelihood to seek help for both physical and mental health conditions, and to explore whether this help-seeking behavior is predicted by a range of sociodemographic and psychological variables.

Methods: 123 participants living in Ireland (cisgender= 67; transgender= 56) completed a questionnaire which included demographic questions, as well as measures of optimism (LOT-R), self-esteem (RSES), psychological distress (GHQ-12), attitudes towards seeking psychological help (ATSPPH-SF), and attitudes towards seeking help for a physical health problem (Attitudes Towards Seeking Medical Help Scale- Action/Intervention subscale). Associations between predictor variables and mental and physical health seeking were explored using correlation analysis and stepwise regressions.

Results: Transgender participants were less likely to seek help for a physical health issue than cisgender participants, but did not differ in mental health help-seeking behaviors. Results suggest that this may be due to differences in optimism, self-esteem and psychological distress. Transgender participants had significantly lower optimism and self-esteem, which were two factors linked to poorer physical health seeking behaviors. Optimism also emerged as a significant predictor in mental health seeking behaviors.

Discussion: The lack of a significant difference for mental health help-seeking between the transgender and cisgender participants is encouraging, as it suggests that there is less stigma surrounding mental illness than expected, however findings also contradict previous findings suggesting that physical health is less stigmatized. This could be due to stigma relating to gender-specific healthcare and suggests that healthcare professionals should acknowledge the specific healthcare needs and concerns among transgender individuals.
