Adults' conceptions of everyday memory failures in others: Factors that mediate the effects of target age.

Investigated young and older adults' conceptions of memory failures in others. 100 young and 100 older adults rated memory failures in targets of 20, 40, 60, and 80 yrs of age as to how likely the memory failures were due to lack of effort or lack of ability. With increasing age, targets' forgetful episodes were rated as less likely to be caused by lack of effort and more likely to be due to lack of ability. A Subject Age?×?Target Age interaction on ability ratings showed age to be more salient for older Ss. Memory content, type of memory, S sex, and target sex all influenced judgment of memory failure. The results support J. T. Erber's (1989) notion of a double standard in memory-failure appraisal; they demonstrated that adults' conceptions of memory include a decremental view of memorial ability with increasing age that is differentially sensitive to S, target, and memorial variables.

Everyday memory failure: Age differences in appraisal and attribution.

A person perception paradigm was used to test 86 young and 84 older Ss for evidence of a double standard in appraising everyday memory failures of young and older targets. Vignettes were judged on separate Likert scales for possible attributions for the failure (ability, effort, task difficulty, chance, and 2 measures of attention), signs of mental difficulty, need for memory training, and indications of need for professional evaluation. Results confirmed a double standard used by young and old: The failures of older targets were judged as signifying greater mental difficulty and greater need for memory training than were the identical failures of young targets. Older Ss were more lenient overall than young Ss in their appraisals. Young Ss judged target persons' memory failures as signifying more mental difficulty, and they more readily recommended professional evaluation.

Effects of age and gender on perceived facial attractiveness.

Examined 2 alternative predictions: (1) that Ss would find others similar to themselves as most attractive or (2) that men would prefer younger women and women more mature men. 22 men and 25 women (aged 17–29 yrs), 16 men and 18 women (aged 30–49 yrs) and 18 men and 32 women (aged 50+ yrs) rated the physical attractiveness of 72 photographs of faces from similar age/gender categories. For all groups of Ss, perceived attractiveness declined with age of face, particularly for women's faces. In addition, most groups rated women's faces as more attractive than those of men, the exception being men under 30 yrs, who rated men higher.

Differential memory changes with age: Exact retrieval versus plausible inference.

Conducted 2 experiments on the use of direct retrieval and plausibility memory strategies in elderly and college-age adults. In Exp I, which used an episodic memory task, data were obtained from 49 65–80 yr old college alumni and from 58 college students who had served in a previous study by the 1st author (see record 1983-02731-001). Findings indicate that older Ss effectively used the plausibility strategy but performed more poorly than younger Ss when the direct retrieval strategy was required. Results of Exp II, using 18 college alumni (8 Ss aged 20–31 yrs, 10 Ss aged 64–75 yrs) with a semantic memory task, show that older Ss' accuracy was essentially undistinguishable from that of younger Ss as long as a plausibility judgment process produced the correct response. It is argued that careful inspection is a much more costly process for older adults than it is for young adults but that plausibility judgments and feature overlap processes are equally easy for both age groups.

Adult age differences in predicting memory performance: The effects of normative information and task experience.

Two experiments addressed the effects of task information and experience on younger and older adults' ability to predict their memory for words. The 1st study, which involved 36 women (aged 20–30 yrs) and 36 women (aged 65–75 yrs), examined the effects of normative task information on Ss' predictions for 30-word lists across 3 trials. The 2nd study, which involved 2 groups of men and women (128 Ss total; aged 19–30 yrs and 54–77 yrs), examined the effects of making predictions and recalling either an easy or a difficult word list prior to making predictions and recalling a moderately difficult word list. Results from both studies showed that task information and experience affected Ss' predictions and that elderly adults predicted their performance more accurately than did younger adults.

Further testing of limits of cognitive plasticity: Negative age differences in a mnemonic skill are robust.

Extended earlier testing-the-limits research on age differences in cognitive plasticity of a memory skill by 18 additional assessment and training sessions to explore whether older adults were able to catch up with additional practice and improved training conditions. The focus was on the method of loci, which requires mental imagination to encode and retrieve lists of words from memory in serial order. Of the original 37 Ss, 35 (16 young, aged 20–30 yrs, and 19 older adults, aged 66–80 yrs) participated in the follow-up study. Older adults showed sizable performance deficits when compared with young adults and tested for limits of reserve capacity. The negative age difference was substantial, resistant to extensive practice, and applied to all Ss studied. The primary origin for this negative age difference may be a loss in the production and use of mental imagination for operations of the mind.

Processing relational and item-specific information: Effects of aging and division of attention.

64 young adults (aged 18–21 yrs) and 32 older Ss (aged 65–83 yrs) encoded items from categorizable lists under incidental learning conditions. Two orienting tasks were used: a category sorting task and a pleasantness rating task. The number of items/category was varied (between 2 and 14) within each list. In addition, 24 young adults performed the orienting tasks while simultaneously engaged in an attention-demanding secondary task (divided-attention condition). Recall declined with both age and division of attention, while recall clustering was greatest for the older Ss and least for the young divided-attention Ss. The effects of category size and orienting task on recall did not vary across groups. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age at first onset for nonbipolar depression.

Examined the onset age distribution for first episodes of unipolar depression for men and women using 2,046 Ss (aged 18–88 yrs) selected for a diagnostic interview on the basis of elevated scores on the Center for Epidemiological Studies Depression Scale. Of those Ss interviewed, 1,012 were diagnosed as having suffered from a previous episode of depression. The Life Table method (S. Anderson et al [1980]; J. D. Kalbfeisch and R. L. Prentice [1980]) was used to describe the risks associated with different ages for developing an initial episode of depression. The results indicate that the hazard rates are very low through age 14 yrs, increase during adolescence (15–29 yrs) and young adulthood (20–24 yrs), peak between 45 and 55 yrs, and then decrease with increasing age, becoming zero at 80 yrs or older. The hazard rates for men and women differed, with women between the ages of 9 and 69 yrs having higher hazard rates than men between the same ages. The average age at onset for first episodes of depression for men and women did not differ. (53 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Episodic spatial memory in adulthood.

Two experiments examined age-related differences in memory for spatial location information in a museum exhibit (Exp 1) and in a secretarial office (Exp 2). In Exp 1, Ss were the visitors to the exhibit (N?=?302, 15–74 yrs of age), and memory was assessed using a map test. In Exp 2, Ss were 64 young adults (M?=?21.2 yrs) and 32 older adults (M?=?71.2 yrs), and memory was assessed using both a map test and a relocation test. The relocation test required Ss to replace the to-be-remembered targets where they appeared at study. Exp 1 showed an age-related decline in spatial memory performance, and it placed the onset of this decline in the 6th decade of life. Exp 2 showed an age-related decline on both tests, but age effects were smaller on the relocation test than on the map test, and when Ss knew that spatial memory would be tested than when they were not informed.

Memory interference effects and aging: Findings from a test of frontal lobe function.

Performance on behavioral measures of self-ordered pointing and 2-choice recognition memory was evaluated in young adults (aged 18–23 yrs) and 2 groups of older adults (aged 61–70 yrs and 71–80 yrs). The self-ordered pointing test involves working memory and has been used as an index of frontal lobe dysfunction; to perform well, Ss must organize stimulus information and monitor responses. Both groups of older adults exhibited impairment on the pointing test, but the pattern of impairment was different for the 2 groups. Individuals in their 60s exhibited impairment on a 2nd block of trials but not on the 1st block. Individuals in their 70s exhibited deficits on both blocks of trials. On the recognition test, only individuals in their 70s exhibited impairment. The findings suggest that age-related impairments occur in both working memory and recognition memory.

Emotions, defenses, coping mechanisms, and symptoms.

Used L. A. Gottschalk and G. C. Gleser's (1969) method of content analysis to examine 5-min samples of speech elicited from 6 different groups of Ss: 30 young normal men (mean age 25.7 yrs), 30 normative adults (aged 20–50 yrs), 30 normative schoolchildren (aged 6–26 yrs), 20 adults with psychoneuroses, 44 emotionally disturbed criminal offenders (mean age 25.6 yrs), and 22 acute schizophrenics (aged 21–55 yrs). Ss were given purposely ambiguous standardized instructions simulating the request to free-associate. Findings indicate that displacements and denials in mentally healthy individuals are more likely to function as coping mechanisms in contrast to their function as defenses or symptoms in mentally disordered people. No significant effects of sex, age, intelligence, or state of consciousness were found. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Comprehension of pronouns in young and older adults.

Explored, in 3 experiments, the issue of whether young (19–37 yrs old) and older (57–84 yrs old) adults differ in their use of pragmatic information in anaphor resolution. 64 Ss from each age group were required to select the antecedent for the pronoun he in sentence pairs such as "Henry spoke at a meeting while John drove to the beach. He brought along a surfboard." Results indicate that young and older Ss were equally influenced by contextual constraints in choosing pronoun referents when the sentence containing the pronoun followed immediately after the context-setting sentence. When extraneous material intervened, however, both age groups became less consistent in their pronoun choices, with older Ss being more affected. Evidence is presented that the failure to use pragmatic constraints in pronoun assignment resulted from inability to recall the relevant contextual information.

Sensibilité et diagnosticité de la mesure de la charge mentale par la tache secondaire de frappe cadencée.

Studied the sensitivity of finger tapping performance as a measure of the mental workload produced by a concurrent memory task. Ss were 8 normal male and female adults (aged 22–39 yrs). Over 4 experimental sessions, Ss were asked to complete 240 series of 13 finger taps at a rate of 1 tap every 2 sec. The concurrent primary task required Ss to search for a target item (presented after each tap) in a 3-digit set memorized before each series of taps. Processing load was varied by including letter targets among positive and negative digit targets. Intertap intervals for letter targets, positive digit targets, and negative digit targets were compared. (English abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Word associations in old age: Evidence for consistency in semantic encoding during adulthood.

Word associations of 80 young (aged 17–33 yrs) and 80 older (aged 62–87 yrs) adults were compared for 113 stimulus words. Results indicate that the proportion of paradigmatic responses varied with the grammatical class of the stimulus word and with the vocabulary level of the S, but not with age. The same proportion of young and older Ss gave the most common responses. Although older Ss had a greater number of unique responses, this seemed to reflect age differences in vocabulary level, as vocabulary but not age was a good predictor. Within-S variability was also comparable across age, as on a retest young and older Ss gave the same proportion of responses that were identical to those on the original test. Both age groups were more likely to repeat common than uncommon responses on the retest. It is concluded that this, together with analyses of response latency, suggests equivalent use of strategic processes across age. The results indicate that semantic structure and semantic encoding in adults are related to verbal ability, but not to age. (49 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Aging and the effects of affective and factual focus on source monitoring and recall.

Pairs of young (aged 17–29 yrs) and elderly (aged 64–77 yrs) Ss participated in a short play and were then instructed to talk about factual or affective aspects of the play or to talk about the play without any particular focus suggested. In both the affective and control condition, older adults' ability to discriminate what they had said from what the other person had said was poorer than that of young adults. In contrast, when induced to focus on the factual content of the events, older Ss' source monitoring improved, and the age difference was reduced. The pattern was similar when Ss' ability to discriminate what they had said from what they had thought was examined. Furthermore, affective focus lowered the overall level of recall for both young and older Ss and led older Ss, in particular, to introduce more elaborations into their recall. The possibility that age differences in remembering content and source are related to type of focus is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effect of contextual organization on spatial memory of middle-aged and older women.

Examined the memory performance of 20 women aged 31–59 yrs and 20 aged 65–85. Ss reconstructed spatial arrays, replacing miniature objects in either a contextually organized panorama or a noncontextually organized bank of cubicles. Performance of the middle-aged Ss did not differ between the 2 tasks. Older Ss performed as well as middle-aged Ss in the panorama task, but in the cubicles task their scores were lower than in the panorama task and lower than those of the younger Ss in the cubicles task. Results support the conclusion that in a task that allows the use of existing contextual organization as a memory aid, age differences in memory performance disappear. Age differences may be limited to tasks that remove previously learned relationships between items (as in recall of lists of unrelated words), requiring Ss to invent an organizational structure to facilitate recall. Though such tasks predominate in research, they probably do not represent the memory problems met in everyday life, especially by older adults.

The effect of imagery on explicit and implicit tests of memory in young and old people: A double dissociation.

Examined the effect of imagery on implicit and explicit tests of memory in young and old adults. 48 undergraduates (mean age 21 yrs) and 64 adults (mean age 72.48 yrs) in Canada were presented with 2 separate word lists in a random order and were assigned to imagery or no-imagery instruction conditions. Ss in the imagery instruction condition read the words to themselves, formed a mental image of it, and rated their ability to do so. Ss in the no-imagery instruction condition simply read the words. All Ss were tested on explicit or implicit memory tests and asked to describe the mnemonic strategies used. Results show that imaging the referent of a visually-presented word improved the performance of the young Ss on the explicit memory test, but reduced their performance on the implicit test. Results of the elderly Ss showed a similar trend but did not reach the level of significance observed for young adults.

The effect of divided attention on memory for items and their context.

Examined differences between item and context memory using divided attention at encoding and retrieval. Ss, in 3 experiments, were presented with word lists and were instructed to learn the items (i.e., words), the intrinsic context (i.e., the color of the cards on which each word was presented), and the extrinsic context (i.e., the temporal order of the words). In Exp 1 24 undergraduates (aged 20–32 yrs) participated in a digit-monitoring and memory tasks. In Exp 2 the authors examined the effect of divided attention at retrieval using 24 undergraduates (aged 18–29 yrs). In Exp 3 the authors examined memory performance when divided attention was employed at encoding on all lists, and attentional load was manipulated at retrieval using 24 undergraduates (aged 19–32 yrs). Among young adults, in comparison to conditions of full attention, divided attention applied at encoding only or retrieval only resulted in equally lower performance on all memory tasks; in contrast, divided attention applied at both encoding and retrieval resulted in lower performance only on memory for temporal order. The findings support the idea that memory for temporal order requires greater attentional resources and strategic processing than memory for items.
