Everyday problem solving in adulthood and old age.

We examined everyday problem solving in adulthood and compared it with traditional measures of cognitive abilities. In the first phase of the research, we describe the construction of an inventory to assess problem solving in situations that adults might encounter in everyday life and examine raters' judgments of effective responses to the problems. In the second phase, adults (N?=?126) between the ages of 20 and 78 were administered the inventory and tests of verbal and abstract problem-solving abilities. Results indicated modest but significant positive correlations between performance on the inventory and traditional ability tests. The examination of age differences revealed that performance on the Everyday Problem-Solving Inventory and verbal ability test increased with age, whereas performance on a traditional problem-solving test declined after middle age. In addition, education was unrelated to everyday problem solving, highly related to verbal ability, and moderately related to traditional problem solving. Results are discussed in relation to pluralistic conceptions of intelligence and theories of adult intellectual development. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Change and consistency in social participation during early adulthood.

Reports a longitudinal study of the social interaction patterns of college students and adults. 113 adults (aged 26–31 yrs old) who had participated in similar studies in college kept detailed records of social activity for 2 wks. Three hypotheses were supported. First, from college to adulthood, opposite-sex socializing grew, whereas same-sex, mixed-sex, and group interactions decreased. Second, intimacy increased in adulthood, whereas satisfaction did not. Contrary to theories that focus on the formation of primary intimate relationships in early adulthood, intimacy increased in all interaction categories. Sex differences in the development of intimacy were also noted. Third, correlations revealed marked consistency over time in several variables. Implications of these findings for social development during early adulthood were examined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memorizing while walking: Increase in dual-task costs from young adulthood to old age.

The dual task of memorizing word lists while walking was predicted to become more difficult with age because balance and gait are in greater need of "attentional resources." Forty-seven young (ages 20–30 years), 45 middle-aged (40–50), and 48 old (60–70) adults were trained to criterion in a mnemonic technique and instructed to walk quickly and accurately on 2 narrow tracks of different path complexity. Then, participants encoded the word lists while sitting, standing, or walking on either track; likewise, speed and accuracy of walking performance were assessed with and without concurrent memory encoding. Dual-task costs increased with age in both domains; relative to young adults, the effect size of the overall increase was 0.98 standard deviation units for middle-aged and 1.47 standard deviation units for old adults. It is argued that sensory and motor aspects of behavior are increasingly in need of cognitive control with advancing age. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Memory Functioning Questionnaire for assessment of memory complaints in adulthood and old age.

[Correction Notice: An erratum for this article was reported in Vol 7(2) of Psychology and Aging (see record 2008-10518-001). In the article, the author note at the beginning of the article was missing a statement. The correct information is included in the erratum.] The results of psychometric analyses of the Metamemory Questionnaire (MQ) of E. M. Zelinski et al (1980), developed to evaluate perception of everyday memory functioning, are presented for a sample of 343 men and 435 women (aged 16–89 yrs). Exploratory factor analysis yielded 4 correlated factors (General Frequency of Forgetting, Retrospective Functioning, and Mnemonics Usage) that accounted for 36.7% of the variance in responses to the MQ. Factor structure was invariant across age groups (16–54 vs 55–89 yrs), 2 independent samples, and over 3 yrs. Because some of the original MQ scales did not load on the factors, only 64 of the original 92 items were retained for inclusion in the Memory Functioning Questionnaire (MFQ). Internal consistency of MFQ scores is high. The MFQ is therefore reliable for evaluating memory self-appraisals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-esteem development from young adulthood to old age: A cohort-sequential longitudinal study.

The authors examined the development of self-esteem from young adulthood to old age. Data came from the Americans’ Changing Lives study, which includes 4 assessments across a 16-year period of a nationally representative sample of 3,617 individuals aged 25 years to 104 years. Latent growth curve analyses indicated that self-esteem follows a quadratic trajectory across the adult life span, increasing during young and middle adulthood, reaching a peak at about age 60 years, and then declining in old age. No cohort differences in the self-esteem trajectory were found. Women had lower self-esteem than did men in young adulthood, but their trajectories converged in old age. Whites and Blacks had similar trajectories in young and middle adulthood, but the self-esteem of Blacks declined more sharply in old age than did the self-esteem of Whites. More educated individuals had higher self-esteem than did less educated individuals, but their trajectories were similar. Moreover, the results suggested that changes in socioeconomic status and physical health account for the decline in self-esteem that occurs in old age.

Why do semantic priming effects increase in old age? A meta-analysis.

Reports a meta-analysis comparing the size of semantic priming effects on young and older adults' lexical decision and pronunciation latency. The analysis included 15 studies with 49 conditions varying the semantic relatedness of a prime stimulus (single word or whole sentence) and a target word. An effect-size analysis on the difference between young and older adults' semantic priming effect (unrelated minus related latency) indicated that semantic priming effects are reliably larger for older than for young adults. There was no evidence for nonhomogeneity in this age difference across the different conditions. The relationship between young and older adults' semantic priming effects was described by a function with a positive intercept and a slope of 1.0. This pattern of findings favors aging models postulating process-specific slowing rather than general cognitive slowing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

New method for studying semantic encoding in children.

Used a familiarization procedure in 2 experiments investigating word encoding in 40 2nd and 40 6th graders. Previous studies using release from proactive inhibition have indicated that developmental changes on some encoding dimensions occur during this period. It is argued that the dependence of release from proactive inhibition on deliberate recall decreases its pertinence to the process of encoding. Exp I confirmed previous findings that the taxonomic classes animals and body parts are encoded by Ss in both grades. Exp II revealed that Ss in both grades also encode the evaluative connotation of words, a finding that has previously emerged only inconsistently.

Evidence for identity inhibition during selective attention in old adults.

Previous studies of negative priming have shown that, relative to young adults, old adults can effectively suppress location information associated with stimuli, but not information about the identity of stimuli. S. L. Connelly and L. Hasher (1993) attributed this dissociation to an age-related decrement in the inhibitory processes that suppress meaning-bearing information. In this study both identity negative priming and distractor interference in a group of young and old adults are reported. Results force a reconsideration of an age-related decrement in the inhibitory processes underlying the suppression of meaning-bearing information. The results also suggest that whether a relationship between negative priming and interference is observed may depend on whether the 2 measures index the same level of processing.

On the plasticity of intelligence in adulthood and old age: Where Horn and Donaldson fail.

Challenges the critique by J. L. Horn and G. Donaldson (see PA, Vol 57:Issue 4) of the K. W. Schaie and P. B. Baltes research and writings on intelligence in adulthood and old age, contending that it seriously misrepresents Schaie's and Baltes's theoretical positions and data interpretations. It is noted that Schaie and Baltes do not reject in toto the notion of intellectual decline; within the framework of a dialectical interpretation of intelligence in adulthood and old age, they emphasize plasticity as evidenced in large interindividual differences, multidimensionality, multidirectionality, modifiability, and the joint import of age- and cohort-related determinants. When arguing for the adequacy of a fluid-crystallized model of intelligence, Horn and Donaldson's critique conveniently de-emphasizes the empirical significance of cohort effects. Contrary to a process-oriented dialectical view, the critique (assuming fairly invariant and fixed change patterns) espouses a model of adult gerontological development which Schaie and Baltes judge to be anachronistic. It is concluded that Horn and Donaldson present a reactionary critique which, if taken too seriously, is likely to inhibit much-needed progress in the field of intelligence in adulthood and old age.

Evidence for semantic satiation: Repeating a category slows subsequent semantic processing.

Ss repeated a visually presented category word 3 or 30 times and then performed a category matching or category membership task. Performance on items from the repeated category was slower following 30 repetitions, even when the repeated category was irrelevant. Repetition also decreased the effect of an irrelevant word flanking the target when the flanker was a member of the repeated category. Prolonged repetition of a word results in the subjective experience of loss of meaning, or semantic satiation. The authors' chronometric studies suggest that this phenomenological effect may be mediated by fatigue or adaptation of the mental structures or psychological pathways that underlie the representation of meaning.

Low self-esteem is a risk factor for depressive symptoms from young adulthood to old age.

Data from two large longitudinal studies were used to analyze reciprocal relations between self-esteem and depressive symptoms across the adult life span. Study 1 included 1,685 participants aged 18 to 96 years assessed 4 times over a 9-year period. Study 2 included 2,479 participants aged 18 to 88 years assessed 3 times over a 4-year period. In both studies, cross-lagged regression analyses indicated that low self-esteem predicted subsequent depressive symptoms, but depressive symptoms did not predict subsequent levels of self-esteem. This pattern of results replicated across all age groups, for both affective–cognitive and somatic symptoms of depression, and after controlling for content overlap between the self-esteem and depression scales. The results suggest that low self-esteem operates as a risk factor for depressive symptoms at all phases of the adult life span. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of semantic consistency on eye movements during complex scene viewing.

Eye movements were recorded while participants viewed line-drawing pictures of natural scenes in preparation for a memory test (Experiment 1) or to find a target object (Experiment 2). Initial saccades in a scene were not controlled by semantic information in the visual periphery, although fixation densities and fixation durations were affected by semantic consistency. The results are compared with earlier eye-tracking studies, and a qualitative model of eye movement control in scene perception is discussed in which initial saccades in a scene are controlled by visual but not semantic analysis.

Evidence based health care in old age psychiatry

Dopamine D1 agonists differing in efficacy with respect to stimulation of adenylate cyclase activity and other in vitro and in vivo criteria were evaluated for their capacity to modulate the behavioral effects of cocaine in squirrel monkeys. Monkeys were trained either to respond on a fixed-ratio schedule in which lever pressing terminated a stimulus associated with electric shock or to discriminate cocaine from vehicle using a two-lever drug-discrimination procedure. When administered in combination with cocaine, D1 agonists displaying relatively low efficacy (SKF 38393, SKF 75670) attenuated both the rate-altering effects of cocaine on fixed-ratio responding and the discriminative-stimulus effects of cocaine, resulting in overall rightward shifts of the cocaine dose-response functions. Maximal attenuation of the behavioral effects of cocaine by the D1 partial agonists was comparable to that produced by the D1 antagonist SCH 39166. In contrast, D1 agonists displaying relatively high efficacy (SKF 81297, SKF 82958, SKF 83189) either had little effect on or accentuated the rate-altering and discriminative-stimulus effects of cocaine. The results show that D1 partial agonists can act as functional cocaine antagonists and may be viable candidate medications for the management of cocaine addiction.     

Affective experience in adulthood and old age: The role of affective arousal and perceived affect regulation.

The aim of the present study was to investigate age-related differences in self-reported affect in adulthood. Measurement of affect encompassed high- and low-arousal positive and negative affect. The sample consisted of 277 participants who were between 20 and 80 years old. Older participants showed a higher level of low-arousal positive affect and did not significantly differ from the two younger age groups in high-arousal positive affect. Both high- and low-arousal negative affect decreased from middle to older adulthood. Only partially are these age effects explained by sociodemographic characteristics, education, or self-reported health and personality. The perceived regulation of affect in the face of difficulties or threatening situations emerged as a central mediator in the association between age and the three age-graded facets of affect. In contrast, future time perspective had no mediating effect on the age–affect relationship. Results suggest that age-related advantages in perceived affect regulation seem to be one central component of resilience in old age.

Lexical selection and phonological encoding during language production: Evidence for cascaded processing.

The time course of lexicalization during production was explored using a production priming procedure. Participants were presented with pictures to name. Occasionally, a visual target word was presented following a picture, and participants named the word. In Experiments 1A and 1B, phonological priming was found for targets related to the dominant name of a picture, as well as for those related to a near-synonymous name. These results suggest that phonological activation occurs for multiple lexical candidates. In Experiments 2A and 2B, semantic priming was found to arise earlier than phonological priming. In Experiment 3, no priming was found for words phonologically related to category associates, suggesting that the activation of such items is weak. Overall, the results are supportive of a cascaded processing model of lexicalization in which activation spreads continuously from semantic to phonological levels of representation.

Repetition priming effects for newly formed associations are perceptually based: Evidence from shallow encoding and format specificity.

This article is concerned with memory for newly formed associations as displayed on implicit and explicit tests of memory. After studying a list of word pairs, participants were shown the original intact pairs and pairs formed by recombining the original pairs. Pairs were simultaneously presented both at study and at test. In a lexical-decision task in which participants were asked to indicate whether both items were words, responses to intact pairs were faster than to recombined pairs. The size of this association-specific repetition effect was relatively unaffected by a levels-of-processing manipulation, indicating that conceptual processes did not likely contribute to the production of the effect. Furthermore, the effect was not produced when pairs were presented simultaneously at study but sequentially at test, thus highlighting the importance of format of presentation. Finally, in an explicit speeded-recognition task the size of the association-specific effect was largely affected by levels-of-processing manipulation and was revealed even under sequential test presentation suggesting that the associative repetition effects were not contaminated by conscious recollection.?.?.?.?

Complex semantic processing in old age: Does it stay or does it go?

Old adults' (N?=?24) and young adults' (N?=?24) speed of producing exemplars of semantic categories (i.e., semantic fluency) varying in difficulty was assessed both in a standard condition and in a "set-switching" condition where exemplars had to be produced from 2 categories in an alternating manner. "Retrieval-position function" parameters were used to assess speed of semantic access independent of nonsemantic factors. Results suggested age effects in nonsemantic components but not in semantic retrieval per se. Also, age deficits in set switching were relatively subtle. Findings are discussed with relation to issues of domain specificity of age effects as well as of the role of executive control during semantic retrieval and age differences therein.

Evidence for the selective preservation of spatial selective attention in old age

Younger and older adults were tested in 2 versions of the Stroop color-word task: a color-block version in which the color word was adjacent to a color block and a color-word version in which the word was printed in color. An advance cue preceded the stimulus by 100 to 300 ms, indicating where it would appear. Age differences were small on the color-block version and large on the color-word version. These results are consistent with the speculation that posterior brain attention systems responsible for selecting a spatial location are relatively well preserved with advancing age but that anterior brain attention systems responsible for selecting a line of processing are compromised.     

Continuity and change: Assortative marriage and the consistency of personality in adulthood.

How is personality stability possible amid the myriad of social changes and transformations that characterize a human life? We argue that by choosing situations that are compatible with their dispositions and by affiliating with similar others, individuals may set in motion processes of social interchange that sustain their dispositions across time and circumstance. To test this proposition we examined mate selection, using data on married couples from two ongoing longitudinal studies at the Institute of Human Development, University of California, Berkeley. Consistent with other research, the results point to homogamy as a basic norm in marriage. More important, the results show that marriage to a similar other promotes consistency in the intraindividual organization of personality attributes across middle adulthood. We offer some speculations for a more relational approach to the problem of individual continuity and change. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The rank-order consistency of personality traits from childhood to old age: A quantitative review of longitudinal studies.

The present study used meta-analytic techniques to test whether trait consistency maximizes and stabilizes at a specific period in the life course. From 152 longitudinal studies, 3,217 test–retest correlation coefficients were compiled. Meta-analytic estimates of mean population test–retest correlation coefficients showed that trait consistency increased from .31 in childhood to .54 during the college years, to .64 at age 30, and then reached a plateau around .74 between ages 50 and 70 when time interval was held constant at 6.7 years. Analysis of moderators of consistency showed that the longitudinal time interval had a negative relation to trait consistency and that temperament dimensions were less consistent than adult personality traits.
