Goals and everyday problem solving: Manipulating goal preferences in young and older adults.

In the present study, we examined the link between goal and problem-solving strategy preferences in 130 young and older adults using hypothetical family problem vignettes. At baseline, young adults preferred autonomy goals, whereas older adults preferred generative goals. Imagining an expanded future time perspective led older adults to show preferences for autonomy goals similar to those observed in young adults but did not eliminate age differences in generative goals. Autonomy goals were associated with more self-focused instrumental problem solving, whereas generative goals were related to more other-focused instrumental problem solving in the no-instruction and instruction conditions. Older adults were better at matching their strategies to their goals than young adults were. This suggests that older adults may become better at selecting their strategies in accordance with their goals. Our findings speak to a contextual approach to everyday problem solving by showing that goals are associated with the selection of problem-solving strategies.

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)     

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.

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.

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)     

Perceived burdensomeness and suicide ideation in older adults.

Older adults have the highest risk of death by suicide in the United States. Improving our understanding of the factors that lead to increased risk of suicide in older adults will greatly inform our ability to prevent suicide in this high-risk group. Two studies were conducted to test the effect of perceived burdensomeness, a component of the interpersonal-psychological theory of suicide (Joiner, 2005), on suicide ideation in older adults. Further, gender was examined as a moderator of this association to determine if perceived burdensomeness exerted a greater influence on suicide ideation in males. The results of these studies suggest that perceived burdensomeness accounts for significant variance in suicide ideation, even after predictors such as depressive symptoms, hopelessness, and functional impairment are controlled. Gender did not moderate the association. The implications of these findings for treatment of older adults with suicide ideation and elevated suicide risk are discussed.

Perceived self-efficacy domains as predictors of fear of the unknown and fear of dying among older adults.

Using a sample of 167 women and 121 men, aged 65-87, this study tested the hypothesis that self-efficacy beliefs of older persons are significantly stronger predictors of death fears than are demographics, social support, and physical health variables used in earlier predictor models. Standard self-report measures were used to assess all predictor variables, including perceived self-efficacy in 8 different domains. Findings from a series of hierarchical regression analyses that were conducted separately for men and women supported the hypothesis concerning the superiority of self-efficacy variables as predictors of fear of the unknown after death and fear of dying, with spiritual health efficacy and instrumental efficacy being the most potent predictors of death fears for women and men. respectively.

Childhood abuse and current health problems among older adults: The mediating role of self-efficacy.

Objectives: Child abuse has negative consequences on health functioning and the self-concept. Prior studies have garnered support for these relationships in younger adults; yet few studies have looked at the effects of abuse on health in older adults and the psychosocial variables, specifically self-efficacy, that may influence the abuse-health relationship. Methods: Data obtained from the Physical Health and Disability Study were used to explore the impact of child abuse on current medical problems among older adults who were screened on physical disability status (N = 1396, Mean age = 67, SD = 10.2). The study was conducted in South Florida and used a multiethnic sample that is representative of the general population in this area. Results: Child abuse was associated with the number of current medical problems and disability. Child abuse was also related to lower self-efficacy, and self-efficacy explained the relationship between abuse and the number of health problems. Conclusions: There are far-reaching effects of child abuse on older adults' health and self-concept. Health care providers and gerontologists need to be aware that child abuse is a lifelong risk factor for increased disability and specific health problems, especially among the elderly. Future research should examine treatments designed to increase self-efficacy, especially among those who experienced child abuse, and observe any positive effects on health functioning.

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.

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)     

Growth trajectories of exercise self-efficacy in older adults: Influence of measures and initial status.

Objective: This study examined differential trajectories of exercise-related self-efficacy beliefs across a 12-month randomized controlled exercise trial. Method: Previously inactive older adults (N = 144; M age = 66.5) were randomly assigned to one of two exercise conditions (walking, flexibility-toning-balance) and completed measures of barriers self-efficacy (BARSE), exercise self-efficacy (EXSE), and self-efficacy for walking (SEW) across a 12-month period. Changes in efficacy were examined according to efficacy type and interindividual differences. Latent growth curve modeling was employed to (a) examine average levels and change in each type of efficacy for the collapsed sample and by intervention condition and (b) explore subpopulations (i.e., latent classes) within the sample that differ in their baseline efficacy and trajectory. Results: Analyses revealed two negative trends in BARSE and EXSE at predicted transition points, in addition to a positive linear trend in SEW. Two subgroups with unique baseline efficacy and trajectory profiles were also identified. Conclusion: These results shed new light on the relationship between exercise and self-efficacy in older adults. They also highlight the need for strategies for increasing and maintaining efficacy within interventions, namely targeting participants who start with a disadvantage (lower efficacy) and integrating efficacy-boosting strategies for all participants prior to program end.

Instruction by mothers and fathers during problem solving with their young children.

Mothers and fathers of 163 5-year-olds were observed interacting with their children in dyads on 2 separate occasions on a familiar and unfamiliar cognitive activity. Within- and between-family comparisons were conducted. Few differences in the instruction provided by mothers and fathers appeared, and those that did were on the unfamiliar task. On this task, instruction by mothers, within and across families, was more responsive to children's changing skill than was instruction by fathers. Directive and disapproving comments by parents were related to poorer posttest performance by the child. High level of instruction by both parents was related to better posttest performance than was low level of instruction by parents. Contributions of parents to their children's cognitive development are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

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.

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.

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.

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.

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)     

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)
