Age Differences in the Complexity of Emotion Perception

Background/Study Context: The current study examined age differences in the number of emotion components used in the judgment of emotion from facial expressions.

Methods: Fifty-eight younger and 58 older adults were compared on the complexity of perception of emotion from standardized facial expressions that were either clear or ambiguous exemplars of emotion.

Results: Using an intra-individual factor analytic approach, results showed that older adults used more emotion components in perceiving emotion in faces than younger adults. Both age groups reported greater emotional complexity for the clear and prototypical emotional stimuli. Age differences in emotional complexity were more pronounced for the ambiguous expressions compared with the clear expressions.

Conclusion: These findings demonstrate that older adults showed increased elaboration of emotion, particularly when emotion cues were subtle and provide support for greater emotion differentiation in older adulthood.     

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.     

Changes in posed facial expression of emotion across the adult life span

The purpose of this study was to examine changes in the facial expression of emotion across the adult life span. Two positive and two negative emotional expressions were posed by 30 young (21 to 39 years), 30 middle-aged (40 to 59 years), and 30 older (60 to 81 years) healthy, right-handed women. Photographs of the four emotional expressions were rated by independent judges for intensity, accuracy, and confidence. Special features of this study were the use of a neutral face as a nonemotional control, as well as careful cognitive and affective screening procedures for posers and judges. Overall, the expressions of older posers were rated as significantly less accurate and with significantly less confidence than those of younger posers. Although the neutral faces of older posers were rated as significantly more intense than those of younger posers, there were no significant age-related intensity differences for positive and negative emotions. The results are discussed in terms of theoretical models of aging.     

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.     

Effects of aging, message repetition, and note-taking on memory for health information

This study investigated whether repetition improves older adults' memory for health service appointment messages delivered by automated telephone systems. Whereas imposed repetition reduces age differences in memory (Morrow, Leirer, Carver, Tanke, & McNally, 1999), the present study examined the effect of optional repetition. Both older and younger participants in Experiment 1 chose to repeat messages. More repetition, higher cognitive ability (working memory and processing speed), and younger age were associated with better memory for appointment information. The effect of age was eliminated when cognitive ability, but not repetition, was controlled. Thus, older adults used optional repetition in automated systems, but this strategy did not eliminate age differences in memory. In Experiment 2, older as well as younger adults took accurate notes and also repeated messages. Both note-taking and message repetition improved memory for the messages but did not reduce age differences. These findings suggest that older as well as younger adults use presentation strategies in automated messaging systems. Older adults may not take full advantage of these strategies, perhaps because of age-related declines in self-initiated or metacognitive processes.     

Blunted rostral anterior cingulate response during a simplified decoding task of negative emotional facial expressions in alcoholic patients

BACKGROUND: Alcoholism is characterized by deficits in emotional functioning as well as by deficits in cognitive functioning. However, most brain imaging research on alcoholism has focused on cognition rather than emotion. METHOD: We used an event-related functional magnetic imaging approach to examine alcoholics' brain blood oxygenation level dependent (BOLD) response to evaluation of emotional stimuli and to compare their response to that of nonalcoholic controls. The task used was a simplified variant of a facial emotion-decoding task in which subjects determined the intensity level of a target emotion displayed as a facial expression. Facial expressions of happy, sad, anger, disgust, and fear were used as stimuli. RESULTS: Alcoholics and controls did not differ in accurately identifying the intensity level on the simple emotional decoding task but there were significant differences in their BOLD response during evaluation of facial emotion. In general, alcoholics showed less brain activation than nonalcoholic controls. The greatest differences in activation were during decoding of facial expressions of fear and disgust during which alcoholics had significantly less activation than controls in the affective division of the anterior cingulate cortex (ACC). Alcoholics also had significantly less activation than controls in the affective division of the ACC, while viewing sad faces. Only to facial expressions of anger did the alcoholics show significant activation in the affective ACC and in this case, their BOLD response did not significantly differ from that of the controls. CONCLUSION: Alcoholics show a deficit in the function of the affective division of the ACC during evaluation of negative facial emotions that can serve as cues for flight or avoidance. This deficit may underlie some of the behavioral dysfunction in alcoholism.     

Age Differences In Emotion Recognition: Task Demands Or Perceptual Dedifferentiation?

Background/Study Context: Older adults (OA) have consistently shown lower accuracy compared with younger adults (YA) when labeling facial expressions of emotion in multiple choice tasks. However, OA do not show lower accuracy when judging psychological attributes from faces in rating tasks. The authors investigated whether the cognitive demands of multiple choice tasks yields an underestimation of OA emotion recognition ability and whether lower scores by OA in emotion recognition tasks are an instance of age-related dedifferentiated face perception.

Methods: Younger and older adults judged the emotions of faces depicting various expressions using (a) a multiple choice task and (b) a rating task with separate scales for each expression. We computed both accuracy scores and an emotion differentiation index, adapted from previous work on neural activation to different stimulus categories.

Results: Lower OA performance in emotion recognition do not reflect the cognitive demands of a multiple choice task, since age differences also were shown when assessing emotion expressions on independent rating scales. An index calculating differentiation of the emotion expressions supported the hypothesis that age differences in emotion recognition accuracy may reflect age-related perceptual dedifferentiation.

Discussion: Results are consistent with other evidence for perceptual dedifferentiation in OA, including lower OA performance in face recognition tasks, rating faces more similarly to one another on trait dimensions, and less specificity in neural activation to faces.     

Greater negative affect and mixed emotions during spontaneous reactions to sad films in older than younger adults

Older adults may be better able to regulate emotion responses to negative experiences than younger persons when provided instructions, but age group differences in spontaneous emotion responses are poorly understood. The current study determined age group differences in spontaneous reactivity and recovery in negative and positive affects, as well as the co-occurrence of negative and positive affects, following a laboratory mood induction. Younger (n = 71) and older adults (n = 44) rated negative and positive affects before and several times after a negative mood induction involving sad film clips. ANCOVA and multilevel longitudinal modeling in HLM were utilized to determine age group differences in spontaneous reactivity to and recovery from the mood induction, as well as age group differences in co-occurrence of negative and positive affects. Relative to younger adults, older adults reported greater negative affect reactivity to and recovery from the mood induction. Older adults also reported greater co-occurrence of negative and positive affects in response to the mood induction, as compared to younger adults. Thus, older adults reacted more strongly to sad film clips than younger persons, exhibited efficient recovery, and reported greater co-occurrence of negative and positive affects. A fruitful line of future research might determine whether affect co-occurrence facilitates effective 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.     

One voice too many: adult age differences in language processing with different types of distracting sounds.

An experiment is reported that investigated factors that might contribute to age differences in the ability to process spoken language under conditions of competition from various types of background noise. Age differences in recall of spoken sentences were shown to depend on the type of background noise as well as its intensity. Increased intensity levels of just one competing speaker produced differentially greater impairment in older adults than in young adults. Analyses showed that listening performance was predicted not only by individual differences in hearing ability but also by speed of processing, which underscores the combined role of age-related auditory and cognitive changes in processing spoken language.     

Editorial policy

Background/Study Context: Current evidence suggests that dysphoric mood affects the ability to recognize facial emotion.

Methods: In the present study, older adults with and without mild depressive symptoms were asked to complete a task measuring their ability to identify facial affect representative of six different emotions (happiness, surprise, disgust, fear, anger, and sadness).

Results: Consistent with previous findings, results showed that older adults experiencing mild depressive symptoms were less accurate in their ability to recognize facial expressions of fear and anger. No group differences were observed in the recognition of happiness, surprise, disgust, and sadness.

Conclusion: The present study has contributed to previous research by demonstrating that mild depressive symptoms affect the ability to recognize facial emotion in a sample of older adults.     

Avoiding threat in late adulthood: testing two life span theories of emotion

The purpose of the present research was to explore the time course of age-related attentional biases and the role of emotion regulation as a potential mediator of older adults' performance in an emotion dot probe task. In two studies, younger and older adults (N?=?80) completed a visual probe detection task, which presented happy, angry, and sad facial expressions. Across both studies, age influenced attentional responses to angry faces. Results indicated a bias away from angry-related facial emotion information occurring relatively late in attention. Age effects were not attributable to decreasing information processing speed or visuoperceptual function. Current results demonstrated that an age-related attentional preference away from angry facial cues was mediated by efforts to suppress emotion. Findings are discussed in relation to current theories of sociocognitive aging.     

Automatic and Controlled Emotion Regulation in Aging: The Case of Expressive Suppression

Background/Study Context: To explain the high levels of well-being reported by older adults, socioemotional selectivity theory suggests that emotion regulation becomes more automated with age. Hence, the objective of the present study was to determine whether automatic emotion regulation becomes indeed more efficient with age, as controlled regulation becomes less efficient. We tested this hypothesis with regard to a specific emotion regulation strategy, expressive suppression, and a discrete emotion: disgust.

Methods: Disgusting videos were presented to 74 young adults (mean (SD) age: 20.1 (1.8)) and 52 older adults (mean (SD) age: 73.6 (9.3)), randomly assigned to one of three conditions: the control condition, the implicit condition (assessing automatic suppression), and the explicit condition (assessing controlled suppression). The disgust expressed and the disgust felt were analyzed separately with factorial analyses of variance that included age group and regulation condition as between-subject variables.

Results: Our results suggest that automatic and controlled expressive suppression may both be altered in healthy aging. Relative to young adults, older adults do not suppress their facial expressions as much but report feeling less disgust.

Conclusion: Expressive suppression may not become more automated with age. However, the older adults’ ability to suppress facial expressions did not appear to be directly associated with the intensity of their emotions.     

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.     

Avoiding Threat in Late Adulthood: Testing Two Life Span Theories of Emotion

The purpose of the present research was to explore the time course of age-related attentional biases and the role of emotion regulation as a potential mediator of older adults' performance in an emotion dot probe task. In two studies, younger and older adults (N = 80) completed a visual probe detection task, which presented happy, angry, and sad facial expressions. Across both studies, age influenced attentional responses to angry faces. Results indicated a bias away from angry-related facial emotion information occurring relatively late in attention. Age effects were not attributable to decreasing information processing speed or visuoperceptual function. Current results demonstrated that an age-related attentional preference away from angry facial cues was mediated by efforts to suppress emotion. Findings are discussed in relation to current theories of sociocognitive aging.     

Effective regulation of the experience and expression of negative affect in old age

We investigated age differences in the experience and expression of emotion in 64 younger and 62 older adults. By manipulating emotion-regulation instructions, we investigated the effects of age on the control of both the inner experience and the outward expression of emotion. We predicted that there would be age improvements in regulating the inner experience of emotion. Indeed, our results indicated that older adults were more effective than young adults in following instructions to reduce the early experience of negative emotion. There were no age differences in following another emotion-regulation strategy involving the suppression of emotional display. In contrast to the well-documented difficulties in cognitive regulation of other studies, these data suggest that the ability to control experience and expression of emotions operates effectively in older adulthood.     

Coronary artery calcium: associations with brain magnetic resonance imaging abnormalities and cognitive status

OBJECTIVES: To evaluate the association between coronary atherosclerosis and subclinical brain magnetic resonance imaging (MRI) abnormalities and between coronary atherosclerosis and abnormal cognitive function (dementia/mild cognitive impairment). DESIGN: Cross-sectional. SETTING: The Cardiovascular Health Study (CHS), an epidemiological study of risk factors for cardiovascular disease in older adults. PARTICIPANTS: Four hundred nine men and women, mean age 79, recruited from the Pittsburgh center of the CHS. MEASUREMENTS: Coronary atherosclerosis was defined according to the level of coronary artery calcification (CAC), as measured using electronic beam tomography. Subclinical brain MRI abnormalities included ventricular enlargement, white matter hyperintensities, and number of subcortical brain infarcts. Brain MRI and CAC measurements were performed between 1998 and 2000 at the Pittsburgh center of the CHS. Prevalence of brain MRI abnormalities and abnormal cognitive status were examined across quartiles of the CAC score, before and after controlling for age. Multivariate logistic regression models were used to assess whether CAC level was associated with abnormalities of brain MRI or abnormal cognitive status. RESULTS: Older adults with high CAC scores were more likely to have more-severe brain MRI abnormalities, including subcortical infarction and high white matter hyperintensities. The associations between CAC and ventricular enlargement showed a similar but not significant trend. The presence of any of the MRI abnormalities attenuated the association between CAC and abnormal cognitive status. CONCLUSION: Older adults with higher levels of CAC were more likely to have more-severe brain MRI abnormalities and abnormal cognitive status.     

Aging and memory for self-performed tasks: effects of task difficulty and time pressure

An increase in task difficulty or time pressure during the performance of cognitive tasks decreased the ability of older adults to recall the tasks. In Experiments 1 and 2, adult age differences in recall of cognitive tasks were smaller for easier than for more difficult tasks, and, in Experiment 3, adult age differences were smaller for recall of cognitive tasks without time pressure than for recall of cognitive tasks with time pressure. During difficult or time-pressured cognitive tasks, older adults may become anxious about their performance, and they may have trouble inhibiting negative self-evaluative thoughts about their performance. Older adults may thus devote less attention to aspects of the cognitive tasks that would be beneficial for task recall.
