Emotion Regulation and Memory: Differential Associations in Younger and Midlife/Older Adults

Background/Study Context: Older adults may devote more cognitive resources to the processing and regulation of emotion stimuli than younger adults, but no studies have determined associations between episodic memory performance and naturalistic emotion recovery in a mixed-age sample. The current study ascertained if episodic memory scores were associated with emotion recovery in younger and midlife/older adults and if these associations were moderated by age.

Methods: Participants watched a montage of film clips about interpersonal loss. Self-reported negative and positive emotions were assessed prior to the video, immediately after, and again 10 min after the video. Executive functions, processing speed, and episodic memory were assessed.

Results: Participants with better episodic memory recovered more quickly from the mood induction than participants with lower scores. Age moderated the association between joviality recovery and memory. Specifically, there was a significantly stronger, positive association between joviality recovery and memory in midlife/older adults relative to younger adults.

Conclusions: Stronger memory may facilitate emotion recovery, and this may be particularly true for older adults. Older adults with memory impairment may be at risk for emotion dysregulation.     

Emotion complexity and emotion regulation across adulthood

This research used data from a study on daily emotional experience in adulthood to examine the associations between age, emotion complexity, and emotion regulation. Data were drawn from a study of daily stress that included 239 participants ranging in age from 18 to 89 from North Central Florida. Two indicators of emotion complexity were considered: emotion differentiation and the co-occurrence of positive and negative affect. Emotion regulation was assessed in terms of individuals’ likelihood of maintaining adaptive emotion states. There were no age differences in adults’ co-occurrence of positive and negative emotions. In contrast to theories suggesting age would be associated with greater emotion complexity, the findings revealed that older adults had lower differentiation scores than younger adults. Age was also associated with more adaptive patterns of emotion regulation. Specifically, older adults persisted in low negative states and moved out of high negative states more readily than younger adults. Finally, neuroticism, self-concept incoherence, mean daily stress, and emotion complexity were associated with emotion regulation. Notably, adults who reported a greater mix of positive and negative affect moved out of high negative affect states more rapidly than adults with lower co-occurrence scores. This finding is in keeping with a growing body of work suggesting that positive affect promotes recovery from negative affect. Overall, the findings suggest that although emotion complexity is associated with emotion regulation, it does not appear to be a key factor underlying age differences in emotion regulation.     

Perceived Duration of Emotional Events: Evidence for a Positivity Effect in Older Adults

Background/Study Context: Arousal and negative affect modulate the effect of emotion on the subjective experience of the passage of time. Given that older adults are less aroused by negative emotional stimuli, and report lower levels of negative affect, compared with younger adults, the present study examined whether the effect of emotion on time perception differed in older and younger adults.

Methods: Participants performed a temporal bisection task for emotional (i.e., angry, sad, happy) and neutral facial expressions presented at varying temporal intervals.

Results: Older adults perceived the duration of both positive and threatening events longer than neutral events, whereas younger adults only perceived threatening events longer than neutral events.

Conclusion: The results, which are partially consistent with the positivity effect of aging postulated by the socioemotional selectivity theory, are the first to show how the effect of emotion on perceived duration affects older adults, and support previous research indicating that only threatening events prolong perceived duration in younger adults.     

Emotional development across adulthood: differential age-related emotional reactivity and emotion regulation in a negative mood induction procedure

The present study examines the hypothesis that older adults might differentially react to a negative versus neutral mood induction procedure than younger adults. The rationale for this expectation was derived from Socioemotional Selectivity Theory (SST), which postulates differential salience of emotional information and ability to regulate emotions across adulthood. The present data support a view of differential age-related effects of negative mood inductions with greater and more heterogeneous emotional reactivity among older adults, who showed a substantially greater decrease in self-rated pleasantness, calmness, and wakefulness than younger adults. Moreover, relative to the younger adults, emotion regulation in terms of mood repair was more effective among the older adults. The age-related mood effects are discussed in terms of SST and have practical implications for the study of emotion and cognition across adulthood.     

Influences of age on emotional reactivity during picture processing

We compared emotional reactivity to affective pictures for 32 older (60-71 years) and 34 younger (18-23 years) adults. We collected the startle-blink reflex, N1 and P3 components of the probe-evoked event-related brain potential, corrugator electromyogram, heart rate, and self-report measures of pleasure and arousal. Self-report findings indicated that older, compared with younger, adults reported greater overall pleasure and arousal. Older adults also exhibited decreased N1 and P3 amplitude, corrugator activity, and heart rate deceleration compared with younger adults. The startle-blink reflex revealed that older adults exhibited increased startle-blink magnitude compared with younger adults during unpleasant pictures, with no age differences observed for pleasant and neutral contents. These age differences suggest that older adults have differential reactivity to affective picture viewing, and they indicate that age-related changes in emotion are not unitary across response systems.     

Age-related differences in the ability to perceive sad facial expressions

BACKGROUND AND AIMS: Research has shown that the ability to label negative emotions displayed by facial expressions declines with age. Such studies, however, have tended to adopt the Ekman and Friesen (1976) Caucasian faces as their emotional stimuli. The purpose of the current study was to examine whether the age differences in identifying negative emotions are also found using the more recent Japanese and Caucasian Facial Expressions of Emotion (JACFEE). METHODS: In Experiment 1, 29 younger and 29 older individuals performed a verbal labeling emotion identification task (happy, sad, angry, frightened, disgusted, surprised, contemptuous). The ability to identify each emotion as a function of ethnicity across the age groups was examined. In order to reduce the verbal decision-making load on the task, a second experiment was conducted in which 60 younger and 60 older participants performed an emotion-matching task (sad, angry, contemptuous). RESULTS: In Experiment 1, older adults showed a significant decrement in the ability to recognize sad faces compared with younger adults, but no age x face ethnicity interaction was found. In Experiment 2, age differences were found when making same/different judgments regarding two sad faces or a sad and a contemptuous face. CONCLUSIONS: Results suggest that aging has an impact upon perceiving sad facial expressions, that this effect is not mediated by own-race versus other-race faces, and that age effects are not attributable to differences in verbal decision-making.     

Is There a Paradox of Aging: When the Negative Aging Stereotype Meets the Positivity Effect in Older Adults

Background/Study Context: Socioemotional selectivity theory (SST) states that the positivity effect is a result of older adults’ emotion regulation and that older adults derive more emotional satisfaction from prioritizing positive information processing. The authors explored whether the positivity effect appeared when the negative aging stereotype was activated in older adults and also whether the effect differed between mixed and unmixed valence conditions.

Methods: Sixty younger (18–23 years of age) and 60 older (60–87 years of age) adults were randomly assigned to a control group and a priming group, in which the negative aging stereotype was activated. All the participants were asked to select 15 words that best described the elderly from a mixed-word list (positive and negative words were mixed together) and from an unmixed-word list (positive and negative words were separated).

Results: Older adults in the control group selected more positive words, whereas among younger adults, selection did not differ by valence in either the mixed- or unmixed-word list conditions. There were no differences between the positive and negative word choices of the younger and older adults in the priming group. We calculated the differences between the numbers of positive and negative words, and the differences in the older adults’ word choices were larger than those among the younger adults; the differences were also larger in the control group than in the priming group.

Conclusion: The positivity effect worked by choosing positive stimuli rather than avoiding negative stimuli. The role of emotion regulation in older adults was limited, and when the positivity effect faced the effect of the negative aging stereotype, the negative stereotype effect was dominant. Future research should explore the changes in the positivity effect in the face of a positive aging stereotype and what roles other factors (e.g., activation level of the stereotype, arousal level of affective words) might play.     

Five-year alcohol and drug treatment outcomes of older adults versus middle-aged and younger adults in a managed care program

AIMS: This study compared 5-year treatment outcomes of older adults to those of middle-aged and younger adults in a large managed care chemical dependency program. We examined age group differences in individual, treatment and extra-treatment factors, which may influence long-term outcome. DESIGN: Seventy-seven per cent of original study participants completed a telephone interview 5 years after out-patient chemical dependency treatment at Kaiser Permanente. This sample (N = 925) included 65 patients aged 55-77, 296 patients aged 40-54 and 564 patients aged 18-39 (age at baseline). MEASUREMENTS: Measures at follow-up included alcohol and drug use, Addiction Severity Index (ASI), Alcoholics Anonymous Affiliation Scale, social resource and self-reported health questions. Mortality data were obtained from contact with family members of patients as well as automated health plan records. FINDINGS: Older adults were less likely to be drug-dependent at baseline than younger and middle-aged adults, and had longer retention in treatment than younger adults. At 5 years, older adults were less likely than younger adults to have close family or friends who encouraged alcohol or drug use. Fifty-two per cent of older adults reported total abstinence from alcohol and drugs in the previous 30 days versus 40% of younger adults. Older women had higher 30-day abstinence than older men or younger women. Among participants dependent only on alcohol, there were no significant age differences in 30-day abstinence. In logistic regression analysis, age group was not significant. Variables associated with greater age that independently predicted 30-day abstinence in the logistic regression model included longer retention in treatment and having no close family or friends who encouraged alcohol or drug use at 5 years; female gender was also significant. CONCLUSIONS: Results indicate that older adults have favorable long-term outcome following treatment relative to younger adults, but these differences may be accounted for by variables associated with age such as type of substance dependence, treatment retention, social networks and gender. Age differences in these characteristics inform intervention strategies to support long-term recovery of older adults and provide direction for investigation of how age affects outcome.     

Phenomenal characteristics of autobiographical memories for emotional and neutral events in older and younger adults

The authors investigated age-related differences in phenomenal characteristics of autobiographical memories for positive, negative, and neutral events. Younger and older participants were asked to recall two specific memories of each type and then to rate their memories on several sensorial (e.g., visual, taste) and contextual (e.g., location, time) characteristics. The authors found that emotional (both positive and negative) memories contained more sensorial and contextual details than neutral memories in both age groups, whereas positive and negative memories did not differ on most dimensions. In addition, negative memories were associated with a higher intensity of positive feelings and a reduced complexity of storyline in older as compared to younger adults. These results suggest that the effect of emotion on phenomenal characteristics of autobiographical memories is similar in younger and older adults, but that older adults tend to reappraise negative events in a more positive light than younger adults.     

A Positivity Effect in Older Adults’ Memorability Judgments of Pictures

Background/Study Context: A growing literature suggests that older adults are biased to preferentially cognitively process positively valenced information. The authors investigated whether this bias extended to preferential selection of information to remember, and also examined whether the arousal invoked by stimuli biased item selection and memory.

Methods: Thirty older (63–88 years of age) and 30 younger (18–25 years of age) adults viewed emotional (positive, negative) and neutral pictures that varied in arousal (low, high), and were asked to select a subset they deemed memorable (memorability judgments), before recalling pictures. Repeated-measures analyses of variance were conducted to examine aging-related differences in selection and recall of positive, negative, and neutral pictures, and of low- and high-arousal pictures.

Results: Older adults selected more positive pictures as memorable, whereas in younger adults selection did not differ by valence. In both age groups, recall of positive pictures was highest. Older adults selected more low- than high-arousal pictures as memorable, although recall was greater for high- than low-arousal pictures in both age groups.

Conclusion: Findings are consistent with the view that the aging-related positivity bias is under cognitive control, and suggest an awareness of this in older adults. Future investigations should seek to disentangle the influence of positive valence from other factors (e.g., perceptual, semantic, arousal level) on older adults’ memorability judgments.     

Hospitalisation,morbidity and outcomes associated with respiratory syncytial virus compared with influenza in adults of all ages

BackgroundRespiratory syncytial virus (RSV) is understood to be a cause of significant disease in older adults and children. Further analysis of RSV in younger adults may reveal further insight into its role as an important pathogen in all age groups.MethodsWe identified, through laboratory data, adults who tested positive for either influenza or RSV between January 2017 and June 2019 at a single Australian hospital. We compared baseline demographics, testing patterns, hospitalisations and outcomes between these groups.ResultsOf 1128 influenza and 193 RSV patients, the RSV cohort was older (mean age 54.7 vs. 64.9, p < 0.001) and was more comorbid as determined by the Charlson Comorbidity Index (2.4 vs. 3.2, p < 0.001). For influenza hospitalisations, the majority admitted were aged under 65 which was not the case for RSV (61.8% vs. 45.6%, p < 0.001). Testing occurred later in RSV hospitalisations as measured by the proportion tested in the emergency department (ED) (80.3% vs. 69.2%, p < 0.001), and this was strongly associated with differences in presenting phenotype (the presence of fever). RSV was the biggest predictor of 6‐month representation, with age and comorbidities predicting this less strongly.ConclusionRSV is a significant contributor to morbidity and hospitalisation, sometimes outweighing that of influenza, and is not limited to elderly cohorts. Understanding key differences in the clinical syndrome and consequent testing paradigms may allow better detection and potentially treatment of RSV to reduce individual morbidity and health system burden. This growing area of research helps quantify the need for directed therapies for RSV.     

Neural and behavioral bases of age differences in perceptions of trust

Older adults are disproportionately vulnerable to fraud, and federal agencies have speculated that excessive trust explains their greater vulnerability. Two studies, one behavioral and one using neuroimaging methodology, identified age differences in trust and their neural underpinnings. Older and younger adults rated faces high in trust cues similarly, but older adults perceived faces with cues to untrustworthiness to be significantly more trustworthy and approachable than younger adults. This age-related pattern was mirrored in neural activation to cues of trustworthiness. Whereas younger adults showed greater anterior insula activation to untrustworthy versus trustworthy faces, older adults showed muted activation of the anterior insula to untrustworthy faces. The insula has been shown to support interoceptive awareness that forms the basis of “gut feelings,” which represent expected risk and predict risk-avoidant behavior. Thus, a diminished “gut” response to cues of untrustworthiness may partially underlie older adults’ vulnerability to fraud.     

Decision strategies in health care choices for self and others: older but not younger adults make adjustments for the age of the decision target

Participants (N = 142 younger and older adults) made health care choices for themselves, a social partner of similar age, or a social partner substantially younger or older than themselves. Using computer-based decision scenarios, participants reviewed positive, negative, or neutral choice criteria before choosing. Older adults who chose for themselves reviewed a greater proportion of positive choice criteria, recalled their choices more positively, and showed more positive emotional responses than did younger adults. Comparable results were found when participants chose for another person of similar age. Older adults who were asked to choose for a young person, however, showed a reduced focus on positive information; in addition, their emotional experience during the review process was less positive. Younger adults' performance was not influenced by the decision target.     

Emotional expressivity in older and younger adults' descriptions of personal memories

Background/Study Context: According to the socioemotional selectivity theory (SST; Mather & Carstensen, 2003, Psychological Sciences, 14, 409-415), aging is associated with greater motivation to regulate emotions. The authors propose that the language people use to describe personal memories provides an index of age differences in emotional self-regulation. Methods: In the present article, the authors reanalyzed three previously published studies in which older (aged 60-88) and younger (aged 17-33) participants described emotional and neutral memories from their recent and distant pasts. The authors analyzed the language of the memories using Pennebaker, Booth, and Francis's ( 2007 ) Linguistic Inquiry Word Count program (Austin, TX: LIWC Inc.), which calculates the percentage of positive and negative emotion words. Results: In Studies 1 and 2, older adults used more positive emotion words than did younger adults to describe their autobiographical memories from the recent past, particularly when these were of a neutral valence. In Study 3, older adults used more positive emotion words when describing more recent memories (from the past 5 years) but not when describing distant childhood or adolescent memories. Conclusion: The authors suggest that these age differences in emotional expressivity support SST, and represent an as-yet unreported age difference that may stem from differences in motivation to regulate emotion.     

Association between age and intellectual curiosity: the mediating roles of future time perspective and importance of curiosity

This study aimed to examine the underlying mechanism behind the association of age and intellectual curiosity. Previous studies generally showed a negative association between age and intellectual curiosity. To shed light on this association, we hypothesize that older adults become more selective in where they invest their curiosity compared with younger adults. The present study (N = 857) first examined the association between age and intellectual curiosity and then the mediation roles of future time perspective and perceived importance of curiosity in the association. The moderation effect of culture was also included to test the generalizability of this model across European Americans, Chinese Americans, and Hong Kong Chinese. The findings suggested that there was a significant negative association between age and intellectual curiosity, even after controlling for sex, culture, and education level. The moderated serial multiple mediation model demonstrated that the indirect effect of age on curiosity through future time perspective and importance of curiosity was significant across all three cultural groups while age did not have a direct effect on intellectual curiosity. This finding suggested that, as future time becomes more limited with age, curiosity is less valued; hence, curiosity is negatively associated with the advance of age. This study illustrates the importance of future time and perceived importance of curiosity in explaining age-related differences in curiosity and sheds light on the situations in which older adults may be as intellectually curious as younger adults.Electronic supplementary materialThe online version of this article (10.1007/s10433-020-00567-6) contains supplementary material, which is available to authorized users.     

The Emotional Stroop as an Emotion Regulation Task

Background/Study Context: The present studies investigate age differences observed when performing the emotional Stroop task considered as an expression of emotion regulation. Previous studies employing this task showed mixed findings regarding age differences, with a lack of evidence for positivity effects. However, moderating factors such as arousal or dispositional (emotion) regulation strategies were mostly not taken into account. Moreover, relations between Stroop effects and emotional reactions were not examined.

Methods: In two studies (Study 1/2: n_young = 26/41; n_old = 19/39), an emotional Stroop task was employed and valence (negative, neutral, positive [Study 2 only]) and arousal of the word stimuli were varied. Additionally, flexible goal adjustment (FGA), positive and negative affect in the last 12 months, and change in momentary affect (Study 2 only) were measured.

Results: Study 1 showed larger emotional Stroop effects (ESE) in older than younger adults with medium arousing negative words. We also found correlations between FGA (positive correlation) as well as negative affect (negative correlation) and the ESE with medium arousing negative words. Study 2 corroborates these findings by exhibiting positive change in momentary affect with larger ESEs for medium arousing negative words in the older age group.

Conclusions: The findings emphasize the importance of including arousal level and dispositional regulation measures (such as FGA) as moderating factors in age differences and within-group differences in emotion regulation. Although we did not find evidence for a positivity effect, processing in the emotional Stroop task was related to positive change in momentary affect and less negative affect in the older age group. Taken together, our experiments demonstrate that the emotional Stroop task is suited as a measure for emotion induction and related emotion regulation mechanisms.     

Emotion in Younger and Older Adults: Retrospective and Prospective Associations with Sleep and Physical Activity

Older adults may have superior emotion regulation skills than younger adults and the authors suggest that as emotion regulation capacities increase with age, emotions may be less swayed by external events or even by internal traits. The current retrospective and prospective study further tested this hypothesis by determining if the emotions of younger adults were more reactive to two behaviors (i.e., physical activity, sleep) than for older adults. Results supported predictions. Specifically, retrospective self-reports and prospective diary data about physical activity and sleep exhibited stronger associations with emotion for younger than older persons. Implications for emotional well-being across the life span are discussed.
