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.     

Attention resources and visible speech encoding in older and younger adults

Two experiments investigated adult age differences in the distribution of attention across a speaker's face during auditory-visual language processing. Dots were superimposed on the faces of speakers for 17-ms presentations, and participants reported the spatial locations of the dots. In Experiment 1, older adults showed relatively better detection performance at the mouth area than the eye area compared to younger adults. In Experiment 2, in the absence of audible language, both age groups did not differentially focus on the mouth area. The results are interpreted in light of Massaro's (1998, Perceiving talking faces: From speech perception to a behavioral principle. Cambridge, MA: MIT Press) theoretical framework for understanding auditory-visual speech perception. It is claimed that older adults' greater reliance on visible speech is due to a reallocation of resources away from the eyes and toward the mouth area of the face.     

The effects of attention switching on encoding and retrieval of words in younger and older adults

Two experiments examined the interaction between aging, attention switching, encoding process, and recognition memory using different versions of a cued attention switching paradigm. In Experiment 1, 30 younger and 35 older adults encoded words based on font color, meaning, or by explicit learning with a color response during performance of a choice-reaction time (RT) task. Attention switches were cued by means of stimulus location, and occurred on average every seven trials. In Experiment 2, attention switching was precued from a central fixation point and the number of critical switch trials was increased, occurring on average every four trials. Memory was assessed in both experiments by means of a forced-choice recognition task. Results indicated that, relative to color encoding, older adults benefited more than younger adults from semantic encoding, but less from explicit learning instructions. Attention switching disrupted encoding task performance of older adults more than that of younger adults, but recognition memory was generally unaffected. Results are discussed in light of theoretical models of aging memory that posit a role for executive control processing.     

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.     

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.     

False Recognition and Source Attribution for Actions of an Emotional Event in Older and Younger Adults

In two experiments recognition of actions of a robbery presented in a video was examined in older and younger adults. In both experiments older adults had more false alarms and showed less accurate recognition than younger adults. In addition, when participants were asked in Experiment 1 to indicate Remember/Know/Guess judgments for actions they considered true, older adults accepted more false actions with Remember judgments. And when participants were asked in Experiment 2 to attribute the source (i.e., perpetrator), the older adults were less able to attribute actions that occurred during the robbery to their correct sources. Furthermore, we found a robust positive correlation between source attribution ability and recognition accuracy. Thus, source-memory deficits may contribute to older adults' false memories in real-life eyewitness situations.

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.     

Age differences in facial trustworthiness perception are diminished by affective processing

While perceptions of facial trustworthiness usually serve as our first references for social interactions, these impressions may ultimately turn out to be inaccurate or unreliable. Compared with younger adults, older adults generally face a higher risk of fraudulent exploitation; the characteristics of older adults’ facial trustworthiness perception may play an important role in revealing the underlying mechanism of their being cheated. Previous studies have demonstrated that, in comparison with their younger counterparts, older adults tend to overestimate strangers’ facial trustworthiness. In the present study, two experiments were conducted, aiming at testing (1) the age-related differences in facial trustworthiness perceptions (Experiment 1) and (2) whether any interventions (e.g., encouraging more deliberative processing or more affective processing) could be applied to help older adults reduce their tendency to overestimate trustworthiness, thus reducing their facial trustworthiness ratings to a lower level (Experiment 2). The results indicated that (1) consistent with previous studies, older adults provided higher trustworthiness ratings for unfamiliar faces than did younger adults (Experiment 1) and (2) more importantly, affective processing instead of deliberative processing could benefit older adults in their assessments of facial trustworthiness, leading them toward demonstrating similar—not significantly higher—levels of trust toward strange faces as younger adults (Experiment 2). A possible mechanism was offered, suggesting that affective processing might help older adults to detect negative cues in unfamiliar faces.

     

Beliefs about memory changes across the adult life span.

Beliefs about age-related differences in memory were examined with an adaptation of the Short Inventory of Memory Experiences. In Experiment 1, 142 adults (mean age = 36 years) reported significantly more positive expectations for memory in everyday life for persons aged 25 years than for those aged 70 years. In Experiment 2, a between-subjects design with 189 adults (mean age = 34 years) was employed to examine the generality of memory beliefs about age-related change and the anticipated slope. Beliefs about the memory of 25-year-olds were significantly more positive than for 45- and 65-year-olds, which were correspondingly higher than for 85-year-olds. Secondary regression analyses revealed that participants with good memory self-perceptions anticipated better memory performance for others overall. In addition, older respondents exhibited more differentiated memory beliefs across age groups than younger respondents, especially at the two younger target ages. Examination of age-based memory beliefs with this type of instrument provides a new opportunity to integrate cognitive and social psychological approaches to the study of memory in aging.     

Ethnic variation in the impact of negative affect and emotion inhibition on the health of older adults

The relations between patterns of emotional experience, emotion inhibition, and physical health have been little studied in older adults or ethnically diverse samples. Testing hypotheses derived from work on younger adults, the authors examined the relations between negative affect and emotion inhibition and that of illness (hypertension, respiratory disease, arthritis, and sleep disorder) in a sample (N = 1,118) of community-dwelling older adults from four ethnic groups: U.S.-born African Americans, African Caribbeans, U.S.-born European Americans, and Eastern European immigrants. Participants completed measures of stress, lifestyle risk factors, health, social support, trait negative emotion, and emotion inhibition. As expected, the interaction of ethnicity with emotion inhibition, and, to a lesser extent, negative affect, was significantly related to illness, even when other known risk factors were controlled for. However, the relations among these variables were complex, and the patterns did not hold for all types of illness or operate in the same direction across ethnic groups. Implications for emotion-health relationships in ethnically diverse samples are discussed.     

Name and face learning in older adults: effects of level of processing, self-generation, and intention to learn

Many older adults are interested in strategies to help them learn new names. We examined the learning conditions that provide maximal benefit to name and face learning. In Experiment 1, consistent with levels-of-processing theory, name recall and recognition by 20 younger and 20 older adults was poorest with physical processing, intermediate with phonemic processing, and best with semantic processing. In Experiment 2, name and face learning in 20 younger and 20 older adults was maximized with semantic processing of names and physical processing of faces. Experiment 3 showed a benefit of self-generation and of intentional learning of name-face pairs in 24 older adults. Findings suggest that memory interventions should emphasize processing names semantically, processing faces physically, self-generating this information, and keeping in mind that memory for the names will be needed in the future.     

Deficit in switching between functional brain networks underlies the impact of multitasking on working memory in older adults

Multitasking negatively influences the retention of information over brief periods of time. This impact of interference on working memory is exacerbated with normal aging. We used functional MRI to investigate the neural basis by which an interruption is more disruptive to working memory performance in older individuals. Younger and older adults engaged in delayed recognition tasks both with and without interruption by a secondary task. Behavioral analysis revealed that working memory performance was more impaired by interruptions in older compared with younger adults. Functional connectivity analyses showed that when interrupted, older adults disengaged from a memory maintenance network and reallocated attentional resources toward the interrupting stimulus in a manner consistent with younger adults. However, unlike younger individuals, older adults failed to both disengage from the interruption and reestablish functional connections associated with the disrupted memory network. These results suggest that multitasking leads to more significant working memory disruption in older adults because of an interruption recovery failure, manifest as a deficient ability to dynamically switch between functional brain networks.     

Word frequency effects in priming performance in young and older adults

The present study examined word frequency effects on implicit priming in older adults compared with younger adults. In Experiment 1 participants performed a spelling test consisting of primed and unprimed homophones (e.g., mourning) and nonhomophones (e.g., militant). Older adults spelled more unprimed, low-frequency homophones than did younger adults, suggesting that there are age-related differences in base-rate spelling of lower frequency homophones. Experiment 2 involved a word-fragment completion task that primed both high- and low-frequency words. Young adults showed larger priming effects for low-frequency words, whereas older adults showed smaller and similar priming effects for high- and low-frequency words. Experiment 3 replicated the finding that word frequency has no effect on priming performance in older adults on a word-fragment completion task. These studies found differential word frequency effects on priming performance between young and older adults.     

Disconfirmation of person expectations by older and younger adults: implications for social vigilance

The research examined whether age-related cognitive declines affect performance when people form impressions of others. The results from Experiment 1 showed that young and old participants who held positive expectancies about an individual spent more time processing and had better memory for information that was inconsistent rather than consistent with their expectancies. But participants who held negative expectancies tended to focus on information that was consistent rather than inconsistent with their expectancies. In Experiment 2 the task was made more demanding by limiting the amount of time participants had to form their impressions. Under these conditions, older participants who had positive expectations showed deficits in memory for negative information compared with young participants. As expected, both groups performed similarly when they held negative expectancies for the target. The results suggest that although both older and younger adults process social information similarly under self-paced conditions, older adults may be at a disadvantage processing negative information about positively characterized individuals when the context in which impression formation occurs is cognitively demanding.     

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.     

Age-related differences in response preparation: the role of time uncertainty

This study explored the ability of younger and older participants to use a variable preparatory interval (PI) to enhance reaction time (RT) performance. In Experiment 1, 30 seniors and 15 young adults completed simple and choice RT tasks with short and long variable PIs. RT decreased with increasing PI duration in both younger and older adults, but the PI effect was larger in elderly individuals. The results of Experiment 2 (20 seniors and 20 young adults) showed an equivalent preparatory effect in older and younger adults when the probability of the shortest PI was increased. These findings suggest that older adults do not prepare as well as younger adults for unlikely events and that time uncertainty affects age-related differences in response preparation.     

Minimal Age-Related Deficits in Task Switching,Inhibition, and Oculomotor Control

Background/Study Context: We are often required to carry out complex tasks in changing, context-dependent ways. This task switching requires the rapid realignment of attention to task constraints and may be age sensitive.

Methods: Three experiments, two in which eye movements were recorded, were conducted to assess age-related differences in task switching and inhibitory control. Observers carried out a Same-Different task and Go-No Go task in single and mixed blocks of trials.

Results: Other than Experiment 1, although switch costs were observed, they were not larger for older adults compared to younger adults. Furthermore, eye movement and false alarm data demonstrated little evidence of age-related decline in inhibitory and oculomotor control.

Conclusions: A major implication is that, at least when two tasks involve different stimuli and unique responses, older adults are no more likely than younger adults to show task-switching costs or inhibition deficit.     

Are older adults more attuned to morally charged information?

Whereas older adults typically show declines in various cognitive processes, they also typically demonstrate greater interest in social relationships. Part of this increased focus on interpersonal relations may extend to morality, which by its very nature is concerned with social contracts, obligations, and the give-and-take among people. The authors tested whether in comparison to younger adults, older adults show increased activation and memory for morally charged information relative to nonmoral information. Three experiments examined older and younger adult comprehension and memory of moral content in stories. Participants read stories and were tested for surface form, textbase, and situation model recognition memory. In contrast to past studies that have not focused on moral content, in this study older adults had textbase memory for moral information equal to that of young adults, suggesting an enhanced attention to morally charged details. To examine online moral inference making, Experiment 2 used lexical decision probes. There was greater facilitation of moral inferences for older adults relative to younger adults, suggesting greater focus of processing on moral content. Experiment 3 explored methodological issues to resolve some discrepancies between the experiments, and replicated the basic findings. In general, older adults had enhanced memory for morally charged story events and, relative to younger adults, were more likely to draw moral inferences during comprehension.
