Attitudes toward older and younger adults: A meta-analysis.

Attitudes toward the elderly have been examined in a number of empirical studies, yet the question of whether the elderly are viewed more negatively than younger persons has not been resolved. A meta-analysis of the literature was conducted to examine this question; results demonstrated that attitudes toward the elderly are more negative than attitudes toward younger people. However, smaller differences between the evaluations of elderly and younger targets were found when (a) the study used measures of personality traits (compared with measures of competence), (b) there were a larger number of dependent measures included in the effect size, (c) specific information was provided about the target person (compared with when a general target such as old person was used), and (d) a between-subjects design (compared with a within-subjects design) was used. These results support Lutsky's (1981) conclusion that age, in and of itself, seems to be less important in determining attitudes toward the elderly than other types of information. The methodological limitations within the literature and a need to consider multiple components of attitudes toward older individuals are discussed.

State-dependent learning in older and younger adults.

In this study state-dependent learning in younger and older adults was compared. State was manipulated by having participants rest or exercise for 5 min, followed by exposure to 3 learning trials of a 20-item word list. After a 20-min delay, participants engaged either in the congruent or in the incongruent activity followed by free-recall trial, cued-recall, and recognition tests. Heart rate, blood pressure, and self-report of distress measures verified that the experimental conditions influenced the participants' physiologic state, but the distracter tasks did not. There was no difference in learning that was due to initial exercise condition, but both age groups showed greater recall when state was congruent before learning and delayed recall. This replicates previous research in which consistent state-dependent learning effects in younger adults were found and supports research suggesting that older adults spontaneously use contextual information to facilitate recall. The demonstration of state-dependent learning in older adults is discussed as an example of implicit memory not affected by aging. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Lexical competition and phonological encoding in young and older speakers.

The influence of age on word retrieval was investigated with a speeded picture naming study. Five hundred forty-one pictures were presented to young and older adults, and the influence of name agreement and name frequency was analyzed by multiple regression. The results showed that both name agreement and name frequency are significant predictors of picture naming performance in young and older adults. The results also suggest that older adults are more strongly influenced by name agreement than are young adults. These results indicate that competition during lexical selection may be a particularly age-sensitive stage in language production. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Activity restriction mediates the association between pain and depressed affect: A study of younger and older adult cancer patients.

Associations are reported frequently among pain, functional disability, and symptoms of depression. The purpose of this longitudinal study was to further clarify relations among these variables. In 268 younger (ages 30–64) and older (ages 65–90) cancer outpatients, cross-sectional analyses replicated previous findings showing that effects of pain on symptoms of depression are mediated by functional disability. Longitudinal analyses revealed that as pain increased over time, so did activity restriction, which in turn predicted increases in depressed affect. Comparative analyses indicate that restriction of routine activities that are due to illness and pain may be more distressing to individuals less than 65 years of age than to those 65 years of age or older. The results suggest that older persons are less distressed by restricted activities because of lower expectations about functional status and more experience with illness and disability.

Memory performance awareness in younger and older adults.

Reports on the course of memory-monitoring skills across adulthood are discrepant in conclusions and limited in scope. The purpose of this study was to build a large data base (3 samples and 7 different tasks) to assess performance awareness. Younger (19–41 years) and older (59–93 years) Ss estimated performance either before (i.e., predictions) or after (i.e., postdictions) completing each task. Predictions were less accurate than postdictions at both age levels, suggesting Ss monitored performance during the study–test cycle. Overall, the data suggested no consistent age effects in performance awareness: Age differences in monitoring occurred only in predictions and only for some tasks. Between-tasks differences in age effects could not be attributed to a single mediating mechanism like those suggested in previous reports. Why previous research has produced conflicting conclusions about metacognitive development in adulthood is discussed in light of these data.

Autobiographical remembering and hypermnesia: A comparison of older and younger adults.

This study examined age differences in autobiographical memory and extended findings concerning hypermnesia in laboratory tasks to a real world event, the announcement of the verdict in the O. J. Simpson murder trial. Older and younger adults repeatedly recalled the event in a single session. Interviews were coded for amount and type of accurate information and for errors. The age groups did not differ in ability to recall the gist of the event or in the number of errors made. Younger adults were better at remembering when the event had occurred. Both age groups showed hypermnesia. The results are discussed in terms of the importance of autobiographical memory across the life span and the phenomenon of hypermnesia in everyday memory.

Intersensory functioning: Auditory-visual pattern equivalence in younger and older children.

Intra- and intersensory auditory–visual pattern equivalence, as well as transposition (temporal–spatial equivalence), was examined in 72 children between the ages of 7 and 17. Increased accuracy in performance was associated with increased age on both intra- and intersensory matching whether or not transposition was required. For the 7-year-old children, intrasensory matching was easier when transposition was not required; however, intersensory matching was easier when transposition was required. Although the requirement of transposition facilitated the performance of the 13-year-old children on intersensory tasks, there was no effect of transposition on the oldest Ss' performance. The findings are discussed in relation to the need to differentiate between types of intersensory functioning. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Oral communication and sales effectiveness.

The relationship between oral communication and sales effectiveness was investigated. 2 equatable groups of working sales people, a more effective "high" group and a less effective "low" group, were compared in terms of selected aspects of their communication behavior. Findings indicated that evaluations of basic oral communication skill (including listening) reliably differentiated between the 2 groups. Sales methods such as using "emotional appeals" and "dramatizing" also distinguished between the more effective and the less effective sales people. Results suggested: that evaluations of basic oral communication skill by a trained interviewer should be one valuable indicator of sales success; that communication training programs should subordinate fragmental, relatively isolated details of communication behavior to consideration of generalized communication skill; and that sales people who are inferior in basic oral communication skill will also be less effective in utilizing specialized persuasive techniques.

Context affects feeling-of-knowing accuracy in younger and older adults.

In feeling of knowing (FOK) studies, participants predict subsequent recognition memory performance on items that were initially encoded but that cannot presently be recalled. Research suggests that FOK judgment magnitude may be influenced by the total amount, or quantity, of contextual information retrieved related to the unrecalled target (e.g., Koriat, 1993). The present study examined the contribution of quality of that information to episodic FOK judgments. In addition, we tested whether the episodic FOK deficit demonstrated by older adults could be reduced by encouraging retrieval of contextual information relevant to the target. Three experiments demonstrated that quality of the retrieved partial information influenced FOK judgments in both older and younger adults; however, the manifestation of that influence was age dependent. The results also indicated that older adults required explicit retrieval of contextual information before making FOK judgments in order to make accurate FOK predictions. The results suggest that FOK accuracy may be partially determined by search processes triggered when participants are queried for contextual information.

Adaptation to visuomotor rotations in younger and older adults.

Adaptation to a visuomotor rotation is known to be impaired at older adult age. The authors examined whether the impairment is present already at preretirement age and whether it depends on the difficulty of the adaptation task. Moreover, the authors tested predictions of the hypothesis that the age-related impairment pertains primarily to strategic corrections and the explicit knowledge on which they are based but not to the acquisition of an (implicit) internal model of the novel visuomotor transformation. The authors found an age-related impairment of adaptation and explicit knowledge already at preretirement age but no age-related change of aftereffects. With an incremental simplification of the adaptation task, age-related changes were able to be eliminated. Individual differences of the quality of explicit knowledge were associated with differences of adaptation, but not of aftereffects. When age groups were matched by explicit knowledge, age-related impairments of adaptation largely disappeared. However, a reliable difference remained in one of the experiments, suggesting that other processes of adjustment to a visuomotor rotation might be affected by aging as well.

Factors influencing word naming in younger and older adults.

The present study examined age differences in the influence of 3 factors that previous research has shown to influence word-naming performance. The influence of word frequency, orthographic length, and orthographic neighborhood measures was examined using large-scale regression analyses on the naming latencies for 2,820 words. Thirty-one younger adults and 29 older adults named all of these words, and age differences in the influence of these factors were examined. The results revealed that all 3 factors predicted reliable amounts of variance in word-naming latencies for both groups. However, older adults showed a larger influence of word frequency and reduced influences of orthographic length and orthographic neighborhood density compared with younger adults. Overall, these results suggest that lexical level factors increase in influence in older adults whereas sublexical factors decrease in influence.

Monitoring one's own forgetting in younger and older adults.

The present study examined whether there are age-related differences in the ability to accurately monitor forgetting. Young and older adults studied a mixed list of categorized words, and later recalled items when cued with each category. They then estimated the number of additional items that they did not recall—a form of monitoring one's forgetting. Older adults exhibited impaired memory performance compared with young adults, but also accurately estimated they forgot more information than young adults. Both age groups were fairly accurate in predicting forgetting in terms of resolution, indicating that aging does not impair the ability to monitor forgetting.

On-line processing of written text by younger and older adults.

Word-by-word reading times were measured for young and elderly adults who read single sentences for immediate recall. The reading strategies of young and old were similar in that both groups allocated time to process word-level and constituent-level features. Young and elderly readers differed mainly in how they allocated time for organizational processing: Whereas younger adults allocated extra processing time at sentence boundaries as well as at major and minor clause boundaries, older adults allocated extra time at major and minor clause boundaries only. Results were generally consistent with the notions that processes that are more microlevel (e.g., word access) become automatic with practice and that age deficits are minimal for such processes. Age differences in organization time allocated at clause boundaries, however, suggested age-related limitations in working memory processing.

Cognitive control and lexical access in younger and older bilinguals.

[Correction Notice: An erratum for this article was reported in Vol 35(3) of Journal of Experimental Psychology: Learning, Memory, and Cognition (see record 2009-05251-016). An incorrect figure was printed due to an error in the production process. The correct version of Figure 1b is provided in the correction.] Ninety-six participants, who were younger (20 years) or older (68 years) adults and either monolingual or bilingual, completed tasks assessing working memory, lexical retrieval, and executive control. Younger participants performed most of the tasks better than older participants, confirming the effect of aging on these processes. The effect of language group was different for each type of task: Monolinguals and bilinguals performed similarly on working memory tasks, monolinguals performed better on lexical retrieval tasks, and bilinguals performed better on executive control tasks, with some evidence for larger language group differences in older participants on the executive control tasks. These results replicate findings from individual studies obtained using only 1 type of task and different participants. The confirmation of this pattern in the same participants is discussed in terms of a suggested explanation of how the need to manage 2 language systems leads to these different outcomes for cognitive and linguistic functions.

Fact retrieval in younger and older adults: The role of mental models.

Using a fan effect paradigm, three experiments tested whether younger and older adults differ in the retrieval of integrated and nonintegrated facts, where integration refers to the development of a mental model. Earlier work by G. A. Radvansky and R. T. Zacks (see record 1992-04153-001) had found that as long as facts can be integrated into a single mental model, young adults show no increase in retrieval time or error rates as the size of the subset of related facts increases (i.e., no fan effect). The present studies show a similar pattern for older adults. By contrast, and in confirmation of our previous findings on age differences and the fan effect (L. D. Gerard et al; see record 1991-32781-001), older adults show an exaggerated fan effect, at least in their error rates, on subsets of related facts not easily integrated into a single mental model.

Cognitive monitoring and strategy choice in younger and older adults.

Younger (24- to 39-year-old) and older (60- to 88-year-old) adults learned a list of vocabulary words; one half of the words were studied using a generally more powerful strategy (mnemonic keyword method), and one half mediated with a less powerful approach (generating semantic contexts). Before using these strategies as part of the experiment, neither younger nor older adults judged that the keyword method was more effective and neither group preferred one strategy over the other. After using the strategies and taking a test of strategically studied unfamiliar vocabulary words, the younger subjects reported accurately the relative effectiveness of the two strategies and selected the one that had worked better for them to apply to a subsequent list of vocabulary items. The older participants were not as aware of the differential potency of the strategies and did not rely as much as did the younger subjects on knowledge of strategy utility in making strategy choices. In short, metacognitive awareness of strategy effects produced by monitoring and use of metacognitive awareness in regulating strategy choice were more pronounced in the younger compared with the older sample in this study.

Reading speed and prose memory in older and younger adults.

A method is described for determining the minimum amount of time required to read a proposition in the context of a sentence. This threshold reading time was reliable, stable, and significantly longer for older adults than for younger adults. Prose memory was assessed for texts presented at varying speeds determined by the threshold reading time measure and by a whole-text reading time measure. Recall from these paced conditions was compared with recall from a self-paced condition. In general, age differences in recall tended to increase as the amount of time allowed for processing increased. The results of regression analyses suggest that although the basic speed of processing for a single sentence accounts for substantial variance in prose recall, processes that operate across sentence boundaries are also important and require further specification.

Cognitive skill acquisition and transfer in younger and older adults.

The acquisition of cognitive skills often depends on 1 of (or a combination of) 2 processes, the execution of an algorithm, and the retrieval of problem instances. This study examined the effects of age and repetition of problem instances on the production and verification of solutions to 2 serially presented sets of alphabet arithmetic problems. Analyses of the parameters derived from power-function fits for individuals revealed age differences favoring young adults in improvement span, learning rate, and asymptote. For both age groups, the beneficial effects of repetitions on 1st-set response times were attributable to algorithmic speedup and to the retrieval of instances, whereas improvements in the speed of 2nd-set response times were attributable primarily to item retrieval.

Verbal and visuospatial recall by younger and older subjects: Use of matched tasks.

In this study, 18 older (over age 65, M?=?75.61 years) and 18 younger (below age 40 and over age 17, M?=?26.44 years) healthy volunteers were tested on verbal and visuospatial recall. Tasks were matched on discriminating power. Older Ss performed worse than younger Ss on both tasks. The older Ss also showed a larger deficit in visuospatial than in verbal recall, relative to the younger Ss. These results are consistent with the theory of aging according to which verbal tasks are more resistant to deterioration than are nonverbal tasks. A psychological explanation based on lifetime experience with verbal material is preferred over the physiological explanation advocating faster aging of the right hemisphere.

Object- and location-based inhibition of return in younger and older adults.

When a cued object moves to new spatial coordinates, inhibition of return (IOR) with younger adults is found at the original cued location (location-based IOR) and at the current location of the object (object-based IOR). Older adults, however, show only location-based IOR. To determine whether this pattern of results represents a general age-related deficit in object-based IOR, the authors used static displays in which the placeholders (i.e., objects) were either present (location-based IOR + object-based IOR) or absent (location-based IOR only). Both age groups showed location-based IOR, but the older adults failed to show object-based IOR, consistent with age-related differences in visual pathways.
