The effect of perceived control on self-reported cardiovascular disease incidence across adulthood and old age

Objective: To examine whether rates of change in perceived control are predictive of cardiovascular disease (CVD) incidence across adulthood and old age.

Design: We used the PATH Through Life Project (n = 7103, M = 40, SD = 16; 52% women), a longitudinal panel survey that encompasses three cohorts at Time 1, ages 20–24, 40–44 and 60–64, who have been assessed three times at four-year intervals.

Method: We examined whether rates of change in perceived control were associated with CVD incidence over 8 years of time, over and above that of baseline levels of perceived control and known risk factors for CVD.

Main Outcome Measures: Self-reported CVD incidence.

Results: Increases in perceived control over time were associated with decreased likelihood of 8-year incidence of CVD and these effects were independent of socio-demographics, covariates and baseline levels of perceived control. The effects were consistent across young adulthood, midlife and old age and for men and women.

Conclusions: Findings demonstrate the importance of changes in perceived control as a predictor of CVD incidence across adulthood and old age. We suggest future research using mediation analysis to test reverse causality and mechanisms underlying the effects of perceived control on CVD incidence.     

Age differences in vocal emotion perception: on the role of speaker age and listener sex

Older adults have greater difficulty than younger adults perceiving vocal emotions. To better characterise this effect, we explored its relation to age differences in sensory, cognitive and emotional functioning. Additionally, we examined the role of speaker age and listener sex. Participants (N?=?163) aged 19–34 years and 60–85 years categorised neutral sentences spoken by ten younger and ten older speakers with a happy, neutral, sad, or angry voice. Acoustic analyses indicated that expressions from younger and older speakers denoted the intended emotion with similar accuracy. As expected, younger participants outperformed older participants and this effect was statistically mediated by an age-related decline in both optimism and working-memory. Additionally, age differences in emotion perception were larger for younger as compared to older speakers and a better perception of younger as compared to older speakers was greater in younger as compared to older participants. Last, a female perception benefit was less pervasive in the older than the younger group. Together, these findings suggest that the role of age for emotion perception is multi-faceted. It is linked to emotional and cognitive change, to processing biases that benefit young and own-age expressions, and to the different aptitudes of women and men.     

The effect of familiarity on within-person age judgements from voices

Listeners can perceive a person’s age from their voice with above chance accuracy. Studies have usually established this by asking listeners to directly estimate the age of unfamiliar voices. The recordings used mostly include cross-sectional samples of voices, including people of different ages to cover the age range of interest. Such cross-sectional samples likely include not only cues to age in the sound of the voice but also socio-phonetic cues, encoded in how a person speaks. How age perpcetion accuracy is affected when minimizing socio-phonetic cues by sampling the same voice at different time points remains largely unknown. Similarly, with the voices in age perception studies being usually unfamiliar to listeners, it is unclear how familiarity with a voice affects age perception. We asked listeners who were either familiar or unfamiliar with a set of four voices to complete an age discrimination task: listeners heard two recordings of the same person’s voice, recorded 15 years apart, and were asked to indicate in which recording the person was younger. Accuracy for both familiar and unfamiliar listeners was above chance. While familiarity advantages were apparent, accuracy was not particularly high: familiar and unfamiliar listeners were correct for 68.2% and 62.7% of trials, respectively (chance = 50%). Familiarity furthermore interacted with the voices included. Overall, our findings indicate that age perception from voices is not a trivial task at all times – even when listeners are familiar with a voice. We discuss our findings in the light of how reliable voice may be as a signal for age.

A Longitudinal Process Analysis of Mother–Child Emotional Relationships in a Rural Appalachian European American Community

This prospective longitudinal study examines emotional relationships in 58 Appalachian mother-child dyads observed at home at 5 and 20 months. Between infancy and toddlerhood, 3 of 4 dimensions of dyadic emotional relationships were stable, and three remained continuous in their mean level. Increasing maternal age was associated with greater maternal sensitivity and structuring and with more responsive and involving children. Marital status and father presence in the home as well as maternal openness, parenting knowledge, investment, and satisfaction accounted for effects of maternal age on dyadic emotional relationships. This longitudinal process analysis provides unique insights into temporal dynamics of mother-child emotional relationships and their determinants in an underserved and underresearched US community. Implications for community-specific interventions are discussed.     

EUTOPIA: THE PROMISE OF BIOTECHNOLOGY AND THE REALIGNMENT OF WESTERN AXIALITY

Abstract. This essay discusses the deep perceptual and social changes that the advanced applications of biotechnology could bring in the West. It examines the probable collapse of a fundamental perceptual bipolarity on which the Western mind and social mobilization have been based since its inception in the West: Athens‐‐Jerusalem. This collapse will quite possibly radically reshape Western perceptions of self and nature and will remodel established constellations and modes of social mobilization and social organization. The radical collapse of the preceding established feature of Western modernity is due to take place in the field of biotechnology, since the latter promises to produce a deliverable perfection of flesh and an equally corporeal personal bliss. I call this promise ``eutopia,'' an actual and tangible utopia‐‐ ``a laboratory on the hill.''     

Relationship between respiratory mortality and self-perceptions of aging

Although there is growing evidence that psychological factors affect an individual's susceptibility to respiratory illnesses, psychological predictors of respiratory mortality have received little attention. This study investigated whether an age-specific psychological factor, older individuals’ beliefs about their own aging, predicted the likelihood of their dying from respiratory causes (ICD-9: 460–519). The sample was composed of 620 individuals, aged 50–87 years at baseline, who participated in a longitudinal study with six waves. Our research found that individuals with higher baseline positive self-perceptions of aging were significantly less likely to die of respiratory causes over the next 23 years, after controlling for age, functional health, gender, loneliness, marital status, self-rated health, and socioeconomic status (hazard ratio?=?0.695; p?<?0.005). This is the first study to link individual beliefs about aging to cause-specific mortality. Future research is warranted to further elucidate the relationship between self-perceptions of aging and resistance to respiratory mortality.     

What do targeting positive views on ageing add to a physical activity intervention in older adults? Results from a randomised controlled trial

Objective: Physical activity is a key factor for healthy ageing, yet many older people lead a sedentary lifestyle. Traditional physical activity interventions do not consider the specific needs and views of older adults. As views on ageing are known to be related to health behaviours, the current study evaluates the effectiveness of prompting positive views on ageing within a physical activity intervention.

Design: Randomised controlled trial with three groups aged 65+: Intervention for physical activity with ‘views-on-ageing’-component (n?=?101; IGVoA), and without ‘views-on-ageing’-component (n?=?30; IG), and active control intervention for volunteering (n?=?103; CG).

Main outcome measures: Attitudes towards older adults and physical activity were assessed five weeks before intervention, two weeks, six weeks and 8.5?months after the intervention.

Results: Compared to the IG and CG, positive attitudes towards older adults increased in the IGVoA after the intervention. For IGVoA, the indirect intervention effect on change in activity via change in attitudes towards older adults was reliable.

Conclusion: A ‘views-on-ageing’-component within a physical activity intervention affects change in physical activity via change in views on ageing. Views on ageing are a promising intervention technique to be incorporated into future physical activity interventions for older adults.     

The effect of rebranding generic medicines on drug efficacy and side effects

Objectives: Subjective age is an important correlate of health, well-being, and longevity. So far, little is known about short-term variability in subjective age and the circumstances under which individuals feel younger/older in daily life. This study examined whether (a) older adults’ felt age fluctuates on a day-to-day basis, (b) daily changes in health, stressors, and affect explain fluctuations in felt age, and (c) the daily associations between felt age and health, stressors, or affect are time-ordered.

Method: Using an eight-day daily diary approach, N = 43 adults (60–96 years, M = 74.65, SD = 8.19) filled out daily questionnaires assessing subjective age, health, daily stressors, and affect. Data were analysed using multilevel modelling.

Main outcome measures: Subjective age, health, daily stressors, affect.

Results: Intra-individual variability in felt age was not explained by time but by short-term variability in other variables. Specifically, on days when participants experienced more than average health problems, stress, or negative affect they felt older than on days with average health, stress, or negative affect. No time-ordered effects were found.

Conclusion: Bad health, many stressors, and negative affective experiences constitute circumstances under which older adults feel older than they typically do. Thus, daily measures of subjective age could be markers of health and well-being.     

Correlates of satisfaction with body function and body appearance in middle- and older aged adults: The activity counseling trial (ACT)

Abstract

This study examined the dimensional structure and correlates of body satisfaction among middle-aged and older adult men (n = 471) and women (n = 383) who were participants in the Activity Counseling Trial. Correlates were grouped as (1) fitness parameters, (2) demographic characteristics, and (3) components of subjective well-being. Factor analyses demonstrated that body function and body appearance were independent components of satisfaction in this population. Body composition and cardiorespiratory fitness were directly related to satisfaction with body appearance; however, satisfaction with body function was most strongly related in expected directions to measures of subjective well-being. Age was positively related to both measures of body satisfaction, whereas data on race revealed that blacks were more satisfied with their body appearance and function than whites. The observed relationships for body satisfaction suggest that older adults may value body function more than body appearance. Furthermore, the associations of race and age with body satisfaction have important implications for intervention research.
