Vulnerability of Older Adults to Deception in Prison and Nonprison Contexts.

Media reports frequently depict older adults as victims of deception. The public perceives these stories as particularly salient because older adults are seen as fragile victims taken advantage of because of trusting behaviors. This developmental investigation of deception detection examines older and younger adults interacting in 2 contexts, prison and the "free world," to discover whether older adults are vulnerable to deception. Younger prisoners were found to be lie biased. Older adults were better able to discriminate lies than younger adults, and this effect was localized primarily to older female adults. Findings indicate that discriminability strongly increases from younger to older age for women, whereas men do not show an improvement, as age increases, in making decisions about statement veracity.

Attributions of Fluency in Fame Judgments by Younger and Older Adults.

Judgments about stimulus characteristics are affected by enhanced processing fluency that results from an earlier presentation of the stimulus. By monitoring for an episodic source of processing fluency, younger adults can more easily avoid this influence than can older adults. In Experiment 1, older adults discounted the effects of fluency when task demands encouraged the use of analytic judgments based on general knowledge, rather than an appeal to episodic source monitoring. Younger subjects were not reliably affected by these same task demands and their judgments continued to be affected by processing fluency. In Experiment 2, introduction of more stringent demands led younger adults also to discount the effects of fluency. We conclude that the influence of processing fluency on younger and older adults varies, depending on whether memory for source or general knowledge is put forward in place of fluency as a basis for judgments.

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)     

Memory and Goal Setting: The Response of Older and Younger Adults to Positive and Objective Feedback.

Earlier research suggested that goal setting for memory does not have the same advantages for older adults as for younger adults. Using ideal goal-setting conditions with individualized goals, the authors compared goals plus positive feedback, goals plus objective feedback, and control. Performance increased over trials and was higher for both goal conditions than for control. The positive feedback condition showed the highest goal commitment and motivation. Older adults showed strong performance gains and more motivation and goal commitment than the young. The results showed that older adults can benefit from goal setting under optimal learning and feedback conditions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Descriptive Epidemiology of Lifetime Trauma and the Physical Health Status of Older Adults.

Three issues are evaluated in this study. The 1st involves examining the relationship between exposure to trauma over the life course and physical health status in old age. The 2nd has to do with seeing whether the relationship between trauma and health varies across 3 cohorts of older adults: the young-old (ages 65-74), the old-old (ages 75-84), and the oldest old (age 85 and over). The 3rd issue involves seeing whether the age at which a trauma was encountered is related to health in late life. Data from a nationwide survey of older people (N = 1,518) reveal that trauma is associated with worse health. Moreover, the young-old appear to be at greatest risk. Finally, data suggest that trauma arising between the ages of 18 and 30 years, as well as ages 31 to 64 years, has the strongest relationship with current health.

False Memories: Young and Older Adults Think of Semantic Associates at the Same Rate, but Young Adults Are More Successful at Source Monitoring.

Two experiments explored whether the higher vulnerability to false memories in the DRM (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995) paradigm in older compared to young adults reflects a deficit in source monitoring. In both experiments, adding together the number of falsely recalled critical lures and the number of critical lures produced on a post-recall test asking participants to report items that they had thought of but did not recall, indicated that the critical lures were activated during the experiment equally often in young and older adults. However, older adults were more likely than young adults to say that they had actually heard the lures. When strongly encouraged to examine the origin of memories (Experiment 2), the warning substantially reduced false recall in young but not older adults. These results are consistent with the idea that older adults have more difficulty later identifying the source of information that was activated as a consequence of intact semantic activation processes.

Preserved Spatial Memory Over Brief Intervals in Older Adults.

Two studies compared young and older adults' memory for location information after brief intervals. Experiment 1 found that accuracy of intentional spatial memory for individual locations was similar in young and older participants for set sizes of 3 and 6. Both groups also encoded individual locations in relation to the larger configuration of locations. Experiment 2 showed that like young adults, older adults' latency to respond to a test probe in a letter working memory task was negatively influenced by spatial information that was irrelevant to the task. This interference effect indicated preserved incidental memory for spatial information in older adults. Together, these data suggest that initial encoding of spatial information for relatively small numbers of items is largely preserved in healthy older adults and that representations of spatial information persist over short intervals.

Eye-Fixation Patterns of High- and Low-Span Young and Older Adults: Down the Garden Path and Back Again.

Young and older adults' eye fixations were monitored as they read sentences with temporary ambiguities such as "The experienced soldiers warned about the dangers conducted the midnight raid." Their fixation patterns were similar except that older adults made many regressions. In a 2nd experiment, high- and low-span older adults were compared with high- and low-span young adults. Pint-pass fixations were similar, except low-span readers made many regressions and their total fixation times were longer. High-span readers also used the focus operator "only" (e.g., "Only experienced soldiers warned about the dangers . . .") to immediately resolve the temporary ambiguities. No age group differences were observed. These results are discussed with reference to theories of the role of working memory in sentence processing.

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.

Aging and Repetition Effects: Separate Specific and Nonspecific Influences.

The research reported in this article focuses on processes that contribute to the repetition effect in 2-alternative forced-choice tasks and on how these processes change with age. An analytical approach is presented that allows researchers to discriminate between 2 components of performance. The results of Experiment 1 show that differences in the relative contributions of these 2 processes can produce differences in repetition effects between younger and older adults. Furthermore, as in the negative priming domain, increasing the contribution of 1 of these 2 components can eliminate this age difference. Together, the results argue against the practice of attributing age differences in repetition effects to deficits in any single cognitive process.

Task Complexity and Older Adults' Decision-Making Competence.

This article reports progress in an ongoing research program examining older adults' decision-making competence (DMC). Using a theoretical framework that emphasizes the person-task fit in assessing DMC, the authors report the results of a study comparing older versus younger adults' decision performance on simple and complex tasks about health, finance, and nutrition. The authors hypothesized and found that increasing age and task complexity were related to greater comprehension errors and inconsistency in decision making. Hierarchical regression analyses showed that a large amount of age-related variance in performance on the decision tasks could be accounted for by exogenous social variables, health measures, basic cognitive skills, and attitudinal measures. The discussion emphasizes several directions for future research, including the need to validate the meaning of performance on these tasks for real-life decision processes.

Does the Information Content of an Irrelevant Source Differentially Affect Spoken Word Recognition in Younger and Older Adults?

To determine whether older adults find it difficult to inhibit the processing of irrelevant speech, the authors asked younger and older adults to listen to and repeat meaningless sentences (e.g., "A rose could paint a fish") when the perceived location of the masker (speech or noise) but not the target was manipulated. Separating the perceived location (but not the physical location) of the masker from the target speech produced a much larger improvement in performance when the masker was informational (2 people talking) than when the masker was noise. However, the size of this effect was the same for younger and older adults, suggesting that cognitive-level interference from an irrelevant source was no worse for older adults than it was for younger adults.

Correlated and Coupled Cognitive Change in Older Adults With and Without Preclinical Dementia.

Common factor aging theories state that correlations among cognitive age effects signify a single underlying causal process. The logic underlying this proposition was evaluated by examining correlated cognitive change in a sample of 391 initially nondemented older adults who were tested annually for up to 16 years. Between-person correlations among rates of change (range=.56-.61) were partly attributable to model misspecification and the aggregation of heterogeneous groups of individuals. Correlated within-person cognitive change was much stronger in the cases (.45-.51) than in the noncases (.07-.18). These results demonstrate that correlated change may either signify causal commonality or the cumulative effects of multiple age-related conditions that can affect multiple cognitive systems.

Age-related equivalence and deficit in knowledge updating of cue effectiveness.

Knowledge updating involves learning about cue effectiveness based on task experience. Prior research has yielded inconsistent conclusions regarding age and knowledge updating. To resolve this inconsistency, the authors analyzed the effects of aging within a single paradigm. Participants studied cue-target associates during 2 study-test trials. Cues included rhyme cues and highly effective category cues. On each study-test trial, different items were presented, and participants predicted recall performance, received a cued recall test, and postdicted performance. Knowledge updating was operationalized as an improvement in the accuracy of predictive judgments across trials. An age deficit was evident in improvements in absolute accuracy, whereas age equivalence was evident in relative accuracy. Evidence suggested that deficient inferential processes contributed to the age deficit in knowledge updating. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Aging, Subjective Experience, and Cognitive Control: Dramatic False Remembering by Older Adults.

Recent research suggests that older adults are more susceptible to interference effects than are young adults; however, that research has failed to equate differences in original learning. In 4 experiments, the authors show that older adults are more susceptible to interference effects produced by a misleading prime. Even when original learning was equated, older adults were 10 times as likely to falsely remember misleading information and were much less likely to increase their accuracy by opting not to answer under conditions of free responding. The results are well described by a multinomial model that postulates multiple modes of cognitive control. According to that model, older adults are likely to be captured by misleading information, a form of goal neglect or deficit in inhibitory functions.

Changes in Functional Status Among Older Adults in Japan: Successful and Usual Aging.

This research aimed to chart the trajectories of functional status in old age in Japan and to assess how self-rated health and cognitive functioning differentiate these trajectories and account for interpersonal differences. Data came from a 5-wave panel study of a national sample of 2,200 Japanese older adults between 1987 and 1999. The sample as a whole showed an accelerated increase in functional limitations with age, approximated by a quadratic function. More important, 3 major trajectories of functional change were identified: (a) minimal functional decrement, (b) early onset of functional impairment, and (c) late onset of functional impairment. These findings may serve as useful benchmarks for observations derived from other developed nations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Adult Age Differences in Distinctive Processing: The Modality Effect on False Recall.

Age differences in distinctive processing were investigated by examining the effects of study presentation modality on false recall in younger and older adults using the Deese/Roediger and McDermott paradigm. Participants were presented with study words either visually or auditorily. Older adults did not show the typical reduction in false recall after visual, compared to auditory, study presentation (R.E. Smith & R.R. Hunt, 1998). The authors interpret these results as evidence of reduced distinctive processing on the part of older adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Binocular detection of masked patterns in young and old observers.

A visual pattern embedded in noise is detected appreciably better when the stimulus complex contains interocular cues (dichoptic condition) than when such cues are absent (binoptic condition). In a recent study (F. Speranza, G. Moraglia, & B. A. Schneider, 1995) the authors showed that the relative difference between binoptic and dichoptic thresholds does not change with age. However, older adults showed higher binoptic and dichoptic thresholds, thus suggesting an age-related difficulty with degraded stimulation. In this article the authors first replicated these findings and proceeded next to investigating whether age-related changes in processing efficiency, additive internal noise, and the spatial frequency bandwidth of the detecting filters could account, separately or concurrently, for the elevated thresholds in noise exhibited by the older adults. Results indicate that this increase is not attributable to age-related changes in filter bandwidth or internal noise. Rather, the findings can be explained in terms of a decrease in processing efficiency with age. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Divided Attention in Younger and Older Adults: Effects of Strategy and Relatedness on Memory Performance and Secondary Task Costs.

Divided attention at encoding leads to a significant decline in memory performance, whereas divided attention during retrieval has relatively little effect; nevertheless, retrieval carries significant secondary task costs, especially for older adults. The authors further investigated the effects of divided attention in younger and older adults by using a cued-recall task and by measuring retrieval accuracy, retrieval latency, and the temporal distribution of attentional costs at encoding and retrieval. An age-related memory deficit was reduced by pair relatedness, whereas strategy instructions benefited both age groups equally. Attentional costs were greater for retrieval than for encoding, especially for older adults. These findings are interpreted in light of notions of an age-related associative deficit (M. Naveh-Benjamin, 2000) and age-related differences in the use of self-initiated activities and environmental support (F. I. M. Craik, 1983, 1986).

Eye movements and the perceptual span in older and younger readers.

The size of the perceptual span (or the span of effective vision) in older readers was examined with the moving window paradigm (G. W. McConkie & K. Rayner, 1975). Two experiments demonstrated that older readers have a smaller and more symmetric span than that of younger readers. These 2 characteristics (smaller and more symmetric span) of older readers may be a consequence of their less efficient processing of nonfoveal information, which results in a riskier reading strategy.
