Perceived self-efficacy and everyday problem solving among young and older adults.

This research tested the hypothesis that age differences in both self-efficacy perceptions and problem-solving performance would vary as a function of the ecological relevance of problems to young and older adults. The authors developed novel everyday problem-solving stimuli that were ecologically representative of problems commonly confronted by young adults (young-adult problems), older adults (older adult problems), or both (common problems). Performance on an abstract problem solving task lacking in ecological representativeness (the Tower of Hanoi problem) also was examined. Although young persons had higher self-efficacy beliefs and performance levels on the Tower of Hanoi task problem and the young-adult problems, this pattern reversed in the domain of older adult problems, where the self-efficacy beliefs and performance of older persons exceeded those of the young.

Age Differences in Everyday Problem-Solving and Decision-Making Effectiveness: A Meta-Analytic Review.

The authors report a meta-analysis of age differences in everyday problem-solving/decision-making effectiveness (EPSE). Effect sizes were calculated to reflect 3 age group comparisons: old versus young, young versus middle-aged, and middle-aged versus old. Findings from the meta-analysis of 28 separate studies with an aggregate of 4,482 participants do not support theories of preserved EPSE in late adulthood. Although significant age differences of moderate magnitude persisted across methodological and theoretical domains, rating criteria (experimenter vs. participant) emerged as a significant moderator of the effect magnitude and direction. In addition, EPSE in older adults was bolstered when problem content was interpersonal and when samples were highly educated. Finally, the current results support the conceptual integration of findings from the everyday problem-solving and everyday decision-making literatures.

Neuropsychological mediators of the links among age, chronic illness, and everyday problem solving.

Reductions in everyday problem solving (EPS) are often reported in older age, although the underlying mechanisms remain unclear. The authors examined the role of 2 variables predicted to mediate (neuropsychological abilities and health status) or moderate (health status) the relationship between age and EPS performance. Toward these ends, they compared EPS and neuropsychological performance in 50 functionally independent adults with chronic kidney disease (CKD) and 64 control participants matched on age and education. Both older age and CKD were associated with worse performance on measures of EPS and memory/executive abilities. Neuropsychological abilities were positively associated with EPS performance. In both the full sample and control participants only, memory/executive functioning mediated the association between presence of chronic illness and EPS. Furthermore, memory/executive functioning partially mediated the link between age and EPS. Findings indicate that relations among age, health status, and EPS are not straightforward. Although performance on neuropsychological measures appeared to underlie EPS declines in chronic illness, increasing age remained independently associated with reduced EPS. The authors discuss implications for models of adult developmental changes in everyday cognition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The structure of verbal abilities in young and older adults.

Four language sample measures as well as measures of vocabulary, verbal fluency, and memory span were obtained from a sample of young adults and a sample of older adults. Factor analysis was used to analyze the structure of the vocabulary, fluency, and span measures for each age group. Then an "extension" analysis was performed by using structural modeling techniques to determine how the language sample measures were related to the other measures. The measure of grammatical complexity was associated with measures of working memory including reading span and digit span. Two measures, sentence length in words and a measure of lexical diversity, were associated with the vocabulary measures. The fourth measure, propositional density, was associated with the fluency measures as a measure of processing efficiency. The structure of verbal abilities in young and older adults is somewhat different, suggesting age differences in processing efficiency.

Verbosity and emotion recognition in older adults.

Previous research suggests that older adults are more verbose than young adults and that general inhibitory difficulties might play a role in such tendencies. In the present study of 60 young adults and 61 older adults, the authors examined whether verbosity might also be related to difficulty deciphering emotional expressions. Measures of verbosity included total talking time, percentage of time spent on-topic, and extremity of off-topic verbosity. Over all 3 measures, older men and women were significantly more verbose than young men and women. Older men's (but not older women's) verbosity was related to poorer emotion recognition, which fully mediated the age effect. The results are consistent with the idea that older men who talk more do so, in part, because they fail to decipher the emotional cues of a listener.

Collaborative everyday problem solving among same-gender friends in early and later adulthood.

To investigate potential age-related differences in performance gains (compensation and optimization) and losses (failure to actualize potential) of collaboration with a familiar partner, the authors compared pairs of older (N = 75; 69% women) and younger (N = 75; 52% women) age-homogeneous same-gender friends who interacted or worked alone to generate strategies for solving interpersonal and instrumental problems. Two indexes of strategy fluency (total and unique number of strategies) and 2 indexes of strategy type (content of strategy repertoires and strategy selected as most effective by older and younger adults) were examined. Strategies generated by interacting pairs were compared with nominal pair scores. Nominal pair scores indexed dyadic potential and were created by pooling the performance of 2 individuals who worked alone. Age differences in strategy fluency and type were largely similar to prior research based on individual problem solvers. Interacting pairs produced fewer strategies than nominal pairs, but there were no differences in strategy type. For interpersonal problems, older adults were relatively more likely to actualize their dyadic potential. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Contextual interference effects in sequence learning for young and older adults.

Practice of different tasks in a random order induces better retention than practicing them in a blocked order, a phenomenon known as the contextual interference (CI) effect. Our purpose was to investigate whether the CI effect exists in sequence learning, such that practicing different sequences in a random order will result in better learning of sequences than practicing them in blocks, and whether this effect is affected by aging. Subjects practiced a serial reaction time task where a set of three 4-element sequences were arranged in blocks or in a random order on 2 successive days. Subjects were divided into 4 groups based on a 2-GROUP (young or old) by 2-ORDER (random or blocked practice) between-subject design. Three days after practice (Day 5), subjects were tested with practiced and novel sequences to evaluate sequence-specific learning. The results replicate the CI effect in sequence learning in both young and older adults. Older adults retained sequences better when trained in a random condition than in a blocked condition, although the random condition incurs greater task switching costs in older adults during practice. Our study underscores the distinction between age-related effects on learning vs. performance, and offers practical implications for enhancing skill learning in older adults.

Preferences for emotional information in older and younger adults: A meta-analysis of memory and attention tasks.

The authors conducted a meta-analysis to determine the magnitude of older and younger adults' preferences for emotional stimuli in studies of attention and memory. Analyses involved 1,085 older adults from 37 independent samples and 3,150 younger adults from 86 independent samples. Both age groups exhibited small to medium emotion salience effects (i.e., preference for emotionally valenced stimuli over neutral stimuli) as well as positivity preferences (i.e., preference for positively valenced stimuli over neutral stimuli) and negativity preferences (i.e., preference for negatively valenced stimuli to neutral stimuli). There were few age differences overall. Type of measurement appeared to influence the magnitude of effects; recognition studies indicated significant age effects, where older adults showed smaller effects for emotion salience and negativity preferences than younger adults.

Recognition of posed and spontaneous dynamic smiles in young and older adults.

In 2 studies, we investigated age effects in the ability to recognize dynamic posed and spontaneous smiles. Study 1 showed that both young and older adult participants were above chance in their ability to distinguish between posed and spontaneous smiles in young adults. In Study 2, we found that young adult participant performance declined when judging a combination of both young and older adult target smiles, while older adult participants outperformed young adult participants in distinguishing between posed and spontaneous smiles. A synthesis of results across the 2 studies showed a small-to-medium age effect (d = ?0.40), suggesting that older adults have an advantage in discriminating between smile types. Mixed stimuli (i.e., a mixture of young and older adult faces) may impact accurate smile discrimination. In future research, both the sources (cues) and behavioral effects of age-related differences in the discrimination of positive expressions should be investigated.

Memory training and strategy use in older adults: Results from the ACTIVE study.

Little is known about the long-term effects of memory training in later life on strategy use. Data from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study (n = 1,401) were used to describe strategy use in a community-dwelling sample of older adults. Strategy clustering scores on verbal list learning tasks of episodic memory were used to test the impact of memory training on strategy use and study longitudinal associations between strategy clustering, memory performance, and everyday functioning. Results suggested that younger, female, white, healthier, and more educated participants show higher strategy clustering scores initially but no characteristics were consistently associated with different trajectories in strategy clustering across all strategy clustering measures together. Memory training had significant immediate effects on all measures of strategy use that were maintained through five years of follow-up. With respect to longitudinal mediation, pre-post training changes in most strategy clustering scores mediate changes in objective memory performance and everyday functioning, implying that strategies can be modified and are closely related to both memory ability and the ability to function independently. This study provides evidence that older adults can be trained to use cognitive strategies, the effects are durable, and strategies are associated with memory and everyday functioning.

Inhibitory deficits in older adults: List-method directed forgetting revisited.

In list-method directed forgetting, participants are cued to intentionally forget a previously studied list while remembering a subsequently presented 2nd list. Results from prior research are inconclusive on whether older adults show deficits in this type of task. In 3 experiments, the authors reexamined the issue and compared younger and older adults' responsiveness to the forget cue. Across the experiments, the forget cue was varied within and between participants, the 2 lists were unrelated and related to each other, and recall of the lists was required simultaneously and successively. In none of the 3 experiments did any age-related difference in directed forgetting performance emerge. List-method directed forgetting is assumed to reflect retrieval inhibition. The present results thus challenge the proposal of a general inhibitory deficit in older adults' memory performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Priming of two-dimensional visual motion is reduced in older adults.

Previously, Y. Jiang, P. Greenwood, and R. Parasuraman (1999) reported that priming of rotating three-dimensional visual objects is age sensitive. The current study investigated whether there is also an age-related difference in priming with simple two-dimensional (2-D) moving stimuli (i.e., whether a prime stimulus moving in a particular direction causes a subsequent ambiguous target stimulus to be seen moving in the same direction as the prime). In 2 experiments, younger and older adults judged the directions of moving sine-wave gratings. Groups differed neither in determining the direction of a single 2-D movement nor in detecting motion reversals in successively moving gratings. However, the older group showed a significant reduction in the extent of 2-D motion priming. The decrement in older adults for visual motion priming may reflect age-related changes in temporal processing in human visual cortex.

Differences and disagreement as factors in creative group problem solving.

"This experiment was designed to test the following hypothesis: conflict generated by increasing the resistance of subordinate members of a group to a solution offered by member in an authority position increases the frequency of high quality solutions. The supplementary hypothesis that mixed-sex composition in interaction with such conflict further enhances the production of high quality solutions was also tested… . The results support the major hypothesis." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Well- and ill-defined measures of everyday cognition: Relationship to older adults' intellectual ability and functional status.

The present study examined 2 approaches to the measurement of everyday cognition in older adults. Measures differing in the degree of structure offered for solving problems in the domains of medication use, financial management, and food preparation and nutrition were administered to a sample of 130 community-dwelling older adults ranging in age from 60 to 90 (M=73 years, SD=7.02 years). Well-defined and ill-defined everyday problem-solving measures, which varied in the amount of means--end-related information provided to participants, were used. The study found that (a) well- and ill-defined measures were moderately interrelated, (b) the 2 approaches were differentially related to basic cognitive abilities, and (c) together the 2 approaches explained over half of the variance in older adults' everyday instrumental functioning and were in fact better predictors of everyday functioning than traditional psychometric cognitive measures. Discussion focuses on the differential importance of both methods for assessing older adults' everyday cognitive functioning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Prose processing in young and old adults: Research on expertise and compensation.

For decades, psychologists have administered a variety of cognitive tasks to adults of all ages and backgrounds. One goal in this research was to answer such global cognitive developmental questions as: Is there inevitable, generalized decline in cognitive performance with advancing age? This article describes the rationale and results of a series of studies investigating the extent to which older adults can develop or maintain such levels of performance in a particular complex cognitive skill, i.e., reading and remembering prose passages. Given that many of the molecular components of these skills decline with advancing age, further improvement or maintenance may occur through a process of compensation.

Time counts: Future time perspective, goals, and social relationships.

On the basis of postulates derived from socioemotional selectivity theory, the authors explored the extent to which future time perspective (FTP) is related to social motivation, and to the composition and perceived quality of personal networks. Four hundred eighty German participants with ages ranging from 20 to 90 yrs took part in the study. In 2 card-sort tasks, participants indicated their partner preference and goal priority. Participants also completed questionnaires on personal networks and social satisfaction. Older people, as a group, perceived their future time as more limited than younger people. Individuals who perceived future time as being limited prioritized emotionally meaningful goals, whereas individuals who perceived their futures as open-ended prioritized instrumental or knowledge-related goals. Priority of goal domains was found to be differently associated with the size, composition, and perceived quality of personal networks depending on FTP. Prioritizing emotion-regulatory goals was associated with greater social satisfaction and less perceived strain with others when participants perceived their future as limited. Findings underscore the importance of FTP in the self-regulation of social relationships and the subjective experience associated with them.

Sending memorable messages to the old: Age differences in preferences and memory for advertisements.

Socioemotional selectivity theory holds that people of different ages prioritize different types of goals. As people age and increasingly perceive time as finite, they attach greater importance to goals that are emotionally meaningful. Because the goals that people pursue so centrally influence cognition, the authors hypothesize that persuasive messages, specifically advertisements, would be preferred and better remembered by older adults when they promise to help realize emotionally meaningful goals, whereas younger adults would not show this bias. The authors also predict that modifying time perspective would reduce age differences. Findings provide qualified support for each of these predictions.

Interference effects from divided attention during retrieval in younger and older adults.

The authors examined how retrieval, under divided attention (DA) conditions, is affected by the type of material in a concurrent task, and whether aging produces larger interference effects on memory. Young and old adults studied a list of unrelated words under full attention, and recalled them while performing either an animacy decision task to words or an odd-digit identification task to numbers. The animacy-distracting task interfered substantially with retrieval, and the size of the effect was not amplified in older compared with younger adults. DA using the odd-digit task did not produce as large an interference effect. These findings support the component-process model of memory, and pose problems for resource models of interference from DA at retrieval.

External support for collaborative problem solving in a simulated provider/patient medication scheduling task.

Taking medication requires developing plans to accomplish the activity. This planning challenges older adults because of age-related cognitive limits and inadequate collaboration with health providers. The authors investigated whether an external aid (medtable) supports collaborative planning in the context of a simulated patient/provider task in which pairs of older adults worked together to create medication schedules. Experiment 1 compared pairs who used the medtable, blank paper (unstructured aid), or no aid to create schedules varying in complexity of medication constraints (number of medications and medication co-occurrence restrictions) and patient constraints (available times during the day to take medication). Both aids increased problem-solving accuracy and efficiency (time per unit accuracy) compared to the no-aid condition, primarily for more complex schedules. However, benefits were similar for the two aids. In Experiment 2, a redesigned medtable increased problem-solving accuracy and efficiency compared to blank paper. Both aids presumably supported problem solving by providing a jointly visible workspace for developing schedules. The medtable may be more effective because it externalizes constraints (relationships between medication and patient information), so that participants can more easily organize information.

Effects of goal-setting and feedback on memory performance and beliefs among older and younger adults.

This research examined the impact of goal-setting conditions on memory beliefs and performance among older and younger adults. After baseline recall and assessment of beliefs, participants were assigned to goal-setting, goals plus feedback, or control. Then, additional recall trials were followed by repeated memory beliefs assessments. For both younger and older adults, performance, motivation, and self-efficacy were affected positively by goal-setting. The impact of goals plus feedback was mixed and varied as a function of age and dependent measure. Success rates for reaching memory goals, which were low for the older adults, may have been a factor in these results. Adults' self-set recall goals were predicted initially by baseline performance and self-efficacy. On the final trial, goals were predicted by last trial performance, self-efficacy, and control beliefs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
