Perceptions of emotion and age among younger, midlife, and older adults

Age-related positivity effect of emotional attention: time and frequency domain

Compared with their younger counterparts, older adults are inclined to allocate more attentional resources to positive over negative materials. This age-related positivity effect has been reported in various experimental paradigms; however, studies have not investigated the attention stage at which it appears or its potential neural mechanism. Thus, we investigated the time and frequency domain dynamics of younger and older adults during emotional attention processes. We obtained electroencephalography oscillation and event-related potential data for 20 older and 20 younger participants while they performed an emotional dot-probe task. We focused our time and frequency domain dynamics analyses on the posterior regions as a key structure for facial emotion perception and the frontal regions as a crucial structure for cognitive control. In the time domain, older adults showed an initial attentional shift to happy-related stimuli, whereas their younger counterparts did not demonstrate emotional modulation, as reflected by the N2pc component. The time-frequency decomposition was analyzed for the N2pc time window. The results showed that compared with younger adults, older adults showed an increased alpha power for happy faces in the right-posterior regions. Moreover, a parallel pattern was seen in frontal theta activity. The current findings highlight how electrocortical activity of the brain might moderate the tendency to prioritize positive information among healthy older adults. The emergence of an age-related positivity effect may be related to frontal cognitive control processing. These findings provide insight into the prevention and treatment of unsuccessful aging, such as late-life depression and anxiety.

Association Between Self-Perceived Stigma and Quality of Life Among Urban Chinese Older Adults: The Moderating Role of Attitude Toward Own Aging and Traditionality

Background

Ageism is a global challenge, which leads to a range of adverse outcomes for elderly people worldwide, which maybe more severe among urban older adults in a competitive society. However, how self-perceived ageism influences the quality of life in a sample of urban older adults remains inconclusive.

Objectives

The current study aims to assess the status of self-perceived stigma among urban Chinese older adults, identify its relationship with quality of life, and further explore whether both attitude toward own aging and traditionality moderate this relationship.

Materials and Methods

Primary data were collected through cross-sectional surveys among urban older adults in three provinces of China from October 2019 to December 2020. A total of 764 urban older adults were valid participants (effective response rate = 81.28%) and completed questionnaires via anonymous face-to-face interviews. Socio-demographic factors, self-perceived stigma, attitude toward own aging, traditionality, and quality of life were assessed using questionnaires that included the Self-perceived Stigma, Attitude Toward Own Aging, Traditionality, and SF-8 Scales.

Results

For urban Chinese older adults, the average score of self-perceived stigma was 2.041 ± 0.726. Self-perceived stigma (β = −0.391, p < 0.05) and attitude toward own aging (β = −0.211, p < 0.05) both influenced quality of life. Additionally, attitude toward own aging (β = −0.530, p < 0.05) and traditionality (β = −0.525, p < 0.05) moderated the association between self-perceived stigma and quality of life. Simple slope analysis revealed that when the level of negative attitude toward own aging and traditionality was higher, the strength of the influence of self-perceived stigma on quality of life was stronger.

Conclusion

Urban Chinese older adults were aware of the self-perceived stigma, which contributes to decreased quality of life. Attitude toward own aging and traditionality could moderate the association between self-perceived stigma and quality of life. When negative attitudes toward own aging and traditionality are higher, self-perceived stigma has a greater effect on the quality of life. More interventions related to relieving self-perceived stigma, traditionality, and negative attitude toward own aging should be considered to build a new modern society that emphasizes health, friendliness, well-being, and dignity for all ages.

Depressive symptoms and deficits in stress-reactive negative, positive, and within-emotion-category differentiation: A daily diary study

OBJECTIVE

The present research aimed to better understand deficits in emotion differentiation that accompany depressive symptoms. Depressive symptoms have been associated with more undifferentiated negative emotion experiences-experiencing multiple negative emotions simultaneously. We extend previous research by asking: (a) Are depressive symptoms and negative and positive emotion differentiation related above and beyond emotion intensity? (b) Are deficits in negative emotion differentiation specific to distinct categories of negative emotions (sadness, guilt, anger, and anxiety)? and (c) Do age or gender predict emotion differentiation or its associations with depressive symptoms?

METHOD

In 220 community participants (59% female; 21-60 years), we assessed depressive symptoms using surveys and emotion differentiation using daily diary emotion ratings in response to daily stressful events.

RESULTS

Greater depressive symptoms were associated with lower negative, but not positive, emotion differentiation, above and beyond emotion intensity. Depressive symptoms were specifically related to lower differentiation among sadness-related emotions, and this sadness-specific deficit accounted for the deficit in negative emotion differentiation. Age and gender did not predict or moderate associations with emotion differentiation.

CONCLUSION

Depressive symptoms are associated with undifferentiated negative emotions above and beyond emotion intensity, and this association appears to be driven by undifferentiated sadness-related emotions, across gender and age.

Older and younger adults differently judge the similarity between negative affect terms

OBJECTIVES

Theoretical models of aging suggest changes across the adult lifespan in the capacity to differentiate emotions. Greater emotion differentiation is associated with advantages in terms of emotion regulation and emotion resiliency. This study utilized a novel method that directly measures judgments of affect differentiation and does not confound affective experience with knowledge about affect terms. Theoretical predictions that older adults would distinguish more between affect terms than younger persons were tested.

METHOD

Older (n = 27; aged 60-92) and younger (n = 56; aged 18-32) adults rated the difference versus similarity of 16 affect terms from the Kessler and Staudinger ( 2009 ) scales; each of the 16 items was paired with every other item for a total of 120 ratings. Participants provided self-reports of trait emotions, alexithymia, and depressive symptoms.

RESULTS

Older adults significantly differentiated more between low arousal and high arousal negative affect (NA) items than younger persons. Depressive symptoms were associated with similarity ratings across and within valence and arousal.

CONCLUSION

Findings offer partial support for theoretical predictions that older adults differentiate more between affect terms than younger persons. To the extent that differentiating between negative affects can aid in emotion regulation, older adults may have an advantage over younger persons. Future research should investigate mechanisms that underlie age group differences in emotion differentiation.
