Aging and emotional memory: Cognitive mechanisms underlying the positivity effect.

Younger adults tend to remember negative information better than positive or neutral information (negativity bias). The negativity bias is reduced in aging, with older adults occasionally exhibiting superior memory for positive, as opposed to negative or neutral, information (positivity bias). Two experiments with younger (N = 24 in Experiment 1, N = 25 in Experiment 2; age range: 18?35 years) and older adults (N = 24 in both experiments; age range: 60?85 years) investigated the cognitive mechanisms responsible for age-related differences in recognition memory for emotional information. Results from diffusion model analyses (R. Ratcliff, 1978) indicated that the effects of valence on response bias were similar in both age groups but that Age × Valence interactions emerged in memory retrieval. Specifically, older adults experienced greater overall familiarity for positive items than younger adults. We interpret this finding in terms of an age-related increase in the accessibility of positive information in long-term memory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does mood state change risk taking tendency in older adults?

No study has been conducted to evaluate the influences of age differences on specific moods for risk taking tendencies. This study examined the patterns of risk taking tendencies among younger and older persons in 3 transient affective states: positive, neutral, and negative moods. By means of viewing happy, neutral, or sad movie clips, participants were induced to the respective mood. Risk taking tendencies were measured with decision tasks modified from the Choice Dilemmas Questionnaire (N. Kogan & M. A. Wallach, 1964). Consistent with the affect infusion model (J. P. Forgas, 1995), risk taking tendency was greater for those individuals who were in a happy mood than for those who were in a sad mood, for both young and older participants. However, an asymmetrical effect of positive and negative mood on risk taking tendency was identified among both the young and older participants, but in opposite directions. These results are consistent with the predictions of the negativity bias and the positivity effect found in young and older adults, respectively, and are interpreted via information processing and motivation effects of mood on the decision maker.

Age-related decline of visual processing components in change detection.

Previous research has suggested that an age-related decline in change detection may be due to older adults using a more conservative response criterion. However, this finding may reflect methodological limitations of the traditional change detection design, in which displays are presented continuously until a change is detected. Across 2 experiments, the authors assessed adult age differences in a version of change detection that required a response after each pair of pre- and postchange displays, thus reducing the potential contribution of response criterion. Older adults performed worse than younger adults, committing more errors and requiring a greater number of display cycles for correct detection. These age-related performance declines were substantially reduced after controlling statistically for elementary perceptual speed. Search strategy was largely similar for the 2 age groups, but perceptual speed was less successful in accounting for age-related variance in detectability when a more precise spatial localization of change was required (Experiment 2). Thus, the negative effect of aging in the present tasks lies in a reduction of detection efficiency due largely to processing speed, though some strategy-level effects may also contribute.

Trust, variability in relationship evaluations, and relationship processes.

Little is known about why some people experience greater temporal fluctuations of relationship perceptions over short periods of time, or how these fluctuations within individuals are associated with relational processes that can destabilize relationships. Two studies were conducted to address these questions. In Study 1, long-term dating partners completed a 14-day diary study that assessed each partner's daily partner and relationship perceptions. Following the diary phase, each couple was videotaped trying to resolve the most important unresolved problem from the diary period. As predicted, (a) individuals who trusted their partners less reported greater variability in perceptions of relationship quality across the diary period; (b) they also perceived daily relationship-based conflict as a relatively more negative experience; and (c) greater variability in relationship perceptions predicted greater self-reported distress, more negative behavior, and less positive behavior during a postdiary conflict resolution task (rated by observers). The diary results were conceptually replicated in Study 2a, in which older cohabiting couples completed a 21-day diary. These same participants also took part in a reaction-time decision-making study (Study 2b), which revealed that individuals tend to compartmentalize positive and negative features of their partners if they (individuals) experienced greater variability in relationship quality during the 21-day diary period and were involved in higher quality relationships. These findings advance researchers' understanding of trust in intimate relationships and provide some insight into how temporal fluctuations in relationship quality may undermine relationships.

Age differences in poignancy: Cognitive reappraisal as a moderator.

Poignancy is defined as a mixed emotional experience that arises when one faces meaningful endings. According to socioemotional selectivity theory (Carstensen, 2006), when people are aware of the finitude of time, they tend to experience more poignancy. In Study 1, we found that Chinese younger, but not older, participants experienced more poignancy under time limitations. In Study 2, we found that an emotion regulation strategy—namely, cognitive reappraisal—moderated the relationship between limited time and poignancy, such that the increases in poignancy under time limitations were found only among older Chinese participants with lower levels of cognitive reappraisal but not among those with higher levels of cognitive reappraisal. These findings contribute to the existing literature on poignancy by showing that not every older adult exhibits poignancy in the face of an ending: The poignancy phenomenon may occur among only older adults who are less likely to use an emotion regulation strategy, such as cognitive reappraisal, to reinterpret the anticipated ending.

Aging and goal-directed emotional attention: Distraction reverses emotional biases.

Previous findings reveal that older adults favor positive over negative stimuli in both memory and attention (for a review, see Mather & Carstensen, 2005). This study used eye tracking to investigate the role of cognitive control in older adults' selective visual attention. Younger and older adults viewed emotional-neutral and emotional-emotional pairs of faces and pictures while their gaze patterns were recorded under full or divided attention conditions. Replicating previous eye-tracking findings, older adults allocated less of their visual attention to negative stimuli in negative-neutral stimulus pairings in the full attention condition than younger adults did. However, as predicted by a cognitive-control-based account of the positivity effect in older adults' information processing tendencies (Mather & Knight, 2005), older adults' tendency to avoid negative stimuli was reversed in the divided attention condition. Compared with younger adults, older adults' limited attentional resources were more likely to be drawn to negative stimuli when they were distracted. These findings indicate that emotional goals can have unintended consequences when cognitive control mechanisms are not fully available.

Isolation and characterization of lectins and lectin-alliinase complexes from bulbs of garlic (Allium sativum) and ramsons (Allium ursinum)

PURPOSE: To evaluate the ophthalmic phenotype in families with three or more individuals who have age-related maculopathy. METHODS: Eight families were identified at academic centers in Massachusetts and North Carolina. Macular findings were graded based on a modification of the grading system used in the Age-Related Eye Disease Study (AREDS). RESULTS: All families had at least three members with stage 3 (extensive drusen change) or higher maculopathy in at least one eye, and six families had at least two members with advanced maculopathy (stage 4, geographic atrophy of the retinal pigment epithelium, or stage 5, exudative maculopathy). Both stages 4 and 5 maculopathy were observed among different individuals in four families. Individuals with stage 3 maculopathy were members of families with more advanced maculopathy (six families) and were of similar age as more severely affected family members but tended to be older than those with stage 2. CONCLUSION: The phenotypic appearance of the macula in families with multiple affected individuals is heterogeneous and representative of the spectrum of macular findings typically associated with age-related maculopathy.     

Age-related differences in recognition memory: Effects of materials and context change.

The study explored age-related differences in the effects of context change on recognition memory by presenting object names (Expt. 1A) or their pictures (Expt. 1B) on background scenes. Participants later attempted to recognize previously presented items on background scenes that were original, switched, blank, or new. Older adults recognized fewer word stimuli than did younger adults, and context effects were larger for older adults. With pictures, however, the age-related decrement was eliminated and context effects were reduced. The beneficial effect of context reinstatement in older adults occurs despite the finding that they are less able to recall or recognize such contexts (Experiment 2). Older adults can use context information in recognition memory at least as efficiently as younger adults when suitable materials and conditions are provided.

On the self-protective nature of inconsistency-negativity management: Using the person memory paradigm to examine self-referent memory.

How do individuals remember feedback that is inconsistent or negative? According to the inconsistency–negativity resolution model, individuals are motivated to reduce uncertainty and resolve inconsistency even when threat to self is potential. They more deeply process and better remember negative self- than other-referent information. According to the inconsistency–negativity neglect model, individuals are motivated to protect the self against threat. They engage in more shallow processing and remember less negative self- than other-referent information. Participants read and recalled either self- or other-referent mixed-valence information. The neglect model was supported in personality and minimal feedback settings. A chronometric exploration of processing mechanisms and the ruling out of a retrieval interference account clarified aspects of the model. Individuals are hypersensitive to threat potential: They will protect the self against even hypothetical threat. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Longevity increased by positive self-perceptions of aging.

This research found that older individuals with more positive self-perceptions of aging, measured up to 23 years earlier, lived 7.5 years longer than those with less positive self-perceptions of aging. This advantage remained after age, gender, socioeconomic status, loneliness, and functional health were included as covariates. It was also found that this effect is partially mediated by will to live. The sample consisted of 660 individuals aged 50 and older who participated in a community-based survey, the Ohio Longitudinal Study of Aging and Retirement (OLSAR). By matching the OLSAR to mortality data recently obtained from the National Death Index, the authors were able to conduct survival analyses. The findings suggest that the self-perceptions of stigmatized groups can influence longevity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Effects of Aging and Divided Attention on Memory for Item and Associative Information.

The present study examined how aging and divided attention influence memory for item and associative information. Older adults and younger adults working under full-attention conditions and younger adults working under divided-attention conditions studied unrelated word pairs. Memory for item information was measured by later recognition of the 2nd word in the pair, and associative information was measured by recognition of the entire pair. Both older adults in the full-attention condition and younger adults in the divided-attention condition performed more poorly than younger adults in the full-attention condition, with the deficit in associative information being greater than the deficit in item information. In addition, a differentially greater associative decrement was found for the older adults, as shown by their heightened tendency to make false-alarm responses to re-paired (conjunction) distractors. The results are discussed in terms of an age-related reduction in processing resources compounded by an age-related increase in older adults' reliance on familiarity in associative recognition memory.

The confirmability and disconfirmability of trait concepts revisited: Does content matter?

M. Rothbart and B. Park (1986) demonstrated that, consistent with the common negativity bias, positive traits are difficult to confirm and easy to disconfirm, whereas the opposite is true for negative traits. This article extends their analysis by showing that trait (dis-)confirmability is moderated by trait content (warmth vs. competence). Study 1 identifies a trait sample representative of warmth and competence. Study 2 shows a strong negativity effect for warmth and a reduced (or absent) negativity effect for competence. Study 3 examines trait properties related to the behavioral range of the trait possessor and to the motivational goals of the perceiver as predictors of trait (dis-)confirmability. The theoretical and practical implications of the authors' findings are discussed, and avenues for future research are suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The differential effects of mood on age differences in the correspondence bias.

The present study found that age-related differences in the correspondence bias were differentially influenced by induced mood. Young and older adults completed an attitude-attribution task after having been induced to experience a positive, neutral, or negative mood. Although negative moods intensified age-related differences in the correspondence bias, young and older adults were equally susceptible to the correspondence bias when in a positive mood. In addition, induced mood differentially influenced the attributional confidence of young and older adults. Whereas negatively induced young adults were less confident than positively induced young adults in their attributions, negatively induced older adults were more confident than positively induced older adults in their attributions. Findings are discussed in terms of how positive and negative moods operate differently in motivating young and older adults' attributional judgments.

The role of the self-concept and the social context in determining the behavior of power holders: Self-construal in intergroup versus dyadic dispute resolution negotiations.

In this work, the authors explored how a person's view of himself or herself might determine his or her use of power in a complex dispute resolution negotiation. In 3 studies of asymmetric power in negotiations, the authors demonstrated that the impact of power on motivation and behavior is moderated by both a person's self-view and the social context. In Study 1, the results revealed that in a one-on-one dispute, powerful individuals primed to hold an interdependent (as opposed to independent) self-construal are more generous in resolving their disputes with low-powered opponents. Study 2 replicated this finding but revealed a different pattern in intergroup disputes, in which powerful interdependent teams of negotiators are actually less generous than are independent teams. Study 3 provided a conceptual replication of Study 2, with the use of chronic measures of self-construal and self-reported measures of behavior. Results suggest that an interdependent self-construal may lead to a more benevolent use of power in dyadic conflicts but more exploitive uses of power in intergroup conflicts. Implications for the understanding of power and self-construal are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Multiple communicators with unique target information transmit less stereotypical impressions.

Four studies examined how multiple communicators who have unique target information transmit less stereotypical impressions. Co-communicators with unique information should feel accountable for providing unique perspectives and consequently will try to be accurate. This accuracy goal should increase their focus on stereotype-incongruent behaviors, resulting in more counterstereotypical transmissions. Study 1 showed that communicators with unique information about an alcoholic target abstractly characterized incongruent attributes and allocated more transmission time to them. Study 2 showed that the effect of communicators' unique information on receivers' less stereotypical impressions was mediated by focus on incongruent attributes. Because the first 2 studies used a target whose stereotypical features were negative, Studies 3 and 4 provided a replication with a target whose stereotypical features were positive.

The framing of relative performance feedback: Seeing the glass as half empty or half full.

It was proposed that individuals' responses to information regarding their relative position in a performance distribution would depend on how they frame the information. To the degree that they focus selectively on the positive features of the feedback (i.e., the number of others who performed worse than them) rather than the negative features (i.e., the number of others who performed better than them) they should report higher ability levels and more positive affective reactions. In Study I, Ss received feedback indicating that they occupied a particular percentile standing in either a large or small distribution. Individuals with negative orientations (depressives and pessimists) reported lower ability levels as a function of increases in comparison group size, whereas individuals with positive orientations (nondepressives and optimists) reported higher ability levels. Presumably, these effects occurred because negatively oriented persons focused on the negative features of the feedback and positively oriented persons focused on the positive features of the feedback. The results of Study 2 support this explanation. Implications for the social comparison literature are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adult age differences in learning from positive and negative probabilistic feedback.

Objective: Past research has investigated age differences in frontal-based decision making, but few studies have focused on the behavioral effects of striatal-based changes in healthy aging. Feedback learning has been found to vary with dopamine levels; increases in dopamine facilitate learning from positive feedback, whereas decreases facilitate learning from negative feedback. Given previous evidence of striatal dopamine depletion in healthy aging, we investigated behavioral differences between college-aged and healthy older adults using a feedback learning task that is sensitive to both frontal and striatal processes. Method: Seventeen college-aged (M = 18.9 years) and 24 healthy, older adults (M = 70.3 years) completed the Probabilistic Selection task, in which participants are trained on probabilistic stimulus-outcome information and then tested to determine whether they learned more from positive or negative feedback. Results: As a group, the older adults learned equally well from positive and negative feedback, whereas the college-aged group learned more from positive than negative feedback, F(1, 39) = 4.10, p effect = .3. However, these group differences were not due to older individuals being more balanced learners. Most individuals of both ages were balanced learners, but while all of the remaining young learners had a positive bias, the remaining older learners were split between those with positive and negative learning biases (χ2(2) = 6.12, p     

Anger management: Age differences in emotional modulation of visual processing.

Although positive and negative images enhance the visual processing of young adults, recent work suggests that a life-span shift in emotion processing goals may lead older adults to avoid negative images. To examine this tendency for older adults to regulate their intake of negative emotional information, the current study investigated age-related differences in the perceptual boost received by probes appearing over facial expressions of emotion. Visually-evoked event-related potentials were recorded from the scalp over cortical regions associated with visual processing as a probe appeared over facial expressions depicting anger, sadness, happiness, or no emotion. The activity of the visual system in response to each probe was operationalized in terms of the P1 component of the event-related potentials evoked by the probe. For young adults, the visual system was more active (i.e., greater P1 amplitude) when the probes appeared over any of the emotional facial expressions. However, for older adults, the visual system displayed reduced activity when the probe appeared over angry facial expressions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

The relationship between racial attitudes and social-cognitive development in children: An Australian study.

Positive and negative racial attitudes of 122 Euro-Australian children (60 girls and 62 boys) toward Euro-, Asian, and Aboriginal Australians were examined across the 5–6-, 7–9-, and 10–12-year age groups. Children were more positive toward Euro- and Asian Australians than toward Aborigines. The middle group were less negative toward Aborigines than were the older and younger groups. Greater maturity in the ability to reconcile different racial perspectives and to perceive between-race similarity was moderately related to greater racial tolerance. Although the results support the role of cognition in age-related changes in prejudice between ages 5 to 9, found by A. B. Doyle and F. E. Aboud (see record 1995-28726-001) in Canadian children, the differences in attitudes to the 2 other groups and the finding that older children's negativity did not differ from that of the youngest group suggest the influence of environmental in addition to cognitive factors in the development of prejudice.
