The Dynamic Effects of Age-Related Stereotype Threat on Explicit and Implicit Memory Performance in Older Adults

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] One of the suggestions made in the literature regarding older adults' episodic memory decline is that it is caused by their reduced ability to bind together components of an episode and retrieve the binding (termed an associative deficit). The purpose of the current research is to assess whether the age-related associative memory deficit is at least partially mediated by stereotype threat, which has been shown to negatively affect performance on a wide variety of cognitive tasks, including memory performance of older adults. To date the effects of stereotype threat on older adults' memory performance have only been shown using tests of item memory, and between subject manipulations. The question assessed in the current research is whether older adults' associative memory will be affected by stereotype threat more than item memory, rendering it one potential factor underlying the associative deficit. To answer this question, three experiments were conducted, which used an item-associative recognition memory paradigm while manipulating stereotype threat both within and between subjects. The first two experiments attempted to establish the baseline effect by directly comparing item and associative memory in younger and older adults under induced stereotype threat, reduced stereotype threat, and no stereotype threat (i.e. control) conditions. While a baseline age-related associative deficit was not shown in the control condition, inducing stereotype threat did have a significant negative effect on older adults' associative memory performance without affecting item memory performance -- suggesting that stereotype threat does increase the age-related associative deficit. The third experiment further assessed the stage of processing -- encoding, retrieval, or both -- during which the effect of stereotype threat on older adults' memory occurs. Results showed that when stereotype threat was induced only at retrieval, memory performance was in line with performance with the reduced stereotype threat and control conditions, suggesting that this effect of stereotype threat occurs primarily during encoding of the information.

Modest Effect

Previous work has shown that memory performance in older adults is affected by activation of a stereotype of age-related memory decline. In the present experiment, we examined whether stereotype threat would affect metamemory in older adults; that is, whether under stereotype threat they make poorer judgments about what they could remember. We tested older adults (MAge = 66.18 years) on a task in which participants viewed words paired with point values and “bet” on whether they could later recall each word. If they bet on and recalled a word, they gained those points, but if they bet on and failed to recall a word, they lost those points. Thus, this task required participants to monitor how much they could remember and prioritize high value items. Participants performed this task over six lists of items either under stereotype threat about age-related memory decline or not under stereotype threat. Participants from both groups performed similarly on initial lists, but on later lists, participants under stereotype threat showed impaired performance as indicated by a lower average point score and a lower average gamma coefficient. The results suggest that a modest effect of stereotype threat on recall combined with a modest effect on metacognitive judgments to result in a performance deficit. This pattern of results may reflect an effect of stereotype threat on executive control reducing the ability to strategically use memory.

Contextual Detail

Abstract. There is now evidence that negative age-related stereotypes about memory reduce older adults’ memory performance, and inflate age differences in this domain. Here, we examine whether stereotype threat may also influence the basic feeling that one is more or less able to remember. Using the Remember/Know paradigm, we demonstrated that stereotype threat conducted older adults to a greater feeling of familiarity with events, while failing to retrieve any contextual detail. This finding indicates that stereotype threat alters older adults’ subjective experience of memory, and strengthens our understanding of the mechanisms underlying stereotype threat effects.

The Relationship ◽

Moderating Role

Studies regularly show that an age-based stereotype threat impairs older adults’ performance on memory tasks. Results regarding stereotype threat effects on false memories are less clear. Some studies suggest that education may moderate the relationship between an age-related stereotype threat and episodic memory performance in older adults. The present study aimed at examining the moderating role of education on the relationship between perceived stereotype threat (PST) and false memories in older adults. With this aim, 82 adults between 60 and 70 years of age performed a Deese-Roediger-McDermott (DRM) task followed by a free recall test and completed questionnaires assessing both their perception of an age-based stereotype threat and their education level. Regression analyses showed no effect of PST on the production of critical lures. However, as was expected, our results showed that in higher educated older adults, as the perception of stereotype increases, the production of critical lures increases. These results confirm the moderating role of education and highlight its key role in the relationship between the age-based stereotype threat and older adults’ susceptibility to false memories.

Episodic Memories

A cardinal feature of aging is a decline in episodic memory (EM). Nevertheless, there is evidence that some older adults may be able to “compensate” for failures in recollection-based processing by recruiting brain regions and cognitive processes not normally recruited by the young. We review the evidence suggesting that age-related declines in EM performance and recollection-related brain activity (left-parietal EM effect; LPEM) are due to altered processing at encoding. We describe results from our laboratory on differences in encoding- and retrieval-related activity between young and older adults. We then show that, relative to the young, in older adults brain activity at encoding is reduced over a brain region believed to be crucial for successful semantic elaboration in a 400–1,400-ms interval (left inferior prefrontal cortex, LIPFC; Johnson, Nessler, & Friedman, 2013 ; Nessler, Friedman, Johnson, & Bersick, 2007 ; Nessler, Johnson, Bersick, & Friedman, 2006 ). This reduced brain activity is associated with diminished subsequent recognition-memory performance and the LPEM at retrieval. We provide evidence for this premise by demonstrating that disrupting encoding-related processes during this 400–1,400-ms interval in young adults affords causal support for the hypothesis that the reduction over LIPFC during encoding produces the hallmarks of an age-related EM deficit: normal semantic retrieval at encoding, reduced subsequent episodic recognition accuracy, free recall, and the LPEM. Finally, we show that the reduced LPEM in young adults is associated with “additional” brain activity over similar brain areas as those activated when older adults show deficient retrieval. Hence, rather than supporting the compensation hypothesis, these data are more consistent with the scaffolding hypothesis, in which the recruitment of additional cognitive processes is an adaptive response across the life span in the face of momentary increases in task demand due to poorly-encoded episodic memories.

Background: Age-related cerebrovascular and neuroinflammatory processes have been independently identified as key mechanisms of Alzheimer’s disease (AD), although their interactive effects have yet to be fully examined. Objective: The current study examined 1) the influence of pulse pressure (PP) and inflammatory markers on AD protein levels and 2) links between protein biomarkers and cognitive function in older adults with and without mild cognitive impairment (MCI). Methods: This study included 218 ADNI (81 cognitively normal [CN], 137 MCI) participants who underwent lumbar punctures, apolipoprotein E (APOE) genotyping, and cognitive testing. Cerebrospinal (CSF) levels of eight pro-inflammatory markers were used to create an inflammation composite, and amyloid-beta 1–42 (Aβ 42), phosphorylated tau (p-tau), and total tau (t-tau) were quantified. Results: Multiple regression analyses controlling for age, education, and APOE ɛ4 genotype revealed significant PP x inflammation interactions for t-tau (B = 0.88, p = 0.01) and p-tau (B = 0.84, p = 0.02); higher inflammation was associated with higher levels of tau within the MCI group. However, within the CN group, analyses revealed a significant PP x inflammation interaction for Aβ 42 (B = –1.01, p = 0.02); greater inflammation was associated with higher levels of Aβ 42 (indicative of lower cerebral amyloid burden) in those with lower PP. Finally, higher levels of tau were associated with poorer memory performance within the MCI group only (p s < 0.05). Conclusion: PP and inflammation exert differential effects on AD CSF proteins and provide evidence that vascular risk is associated with greater AD pathology across our sample of CN and MCI older adults.

The Impact

Cultural stereotypes that equate aging with decreased competence and increased forgetfulness have persisted for decades. Stereotype threat (ST) refers to the psychological discomfort people experience when confronted by a negative, self-relevant stereotype in a situation where their behavior could be construed as confirming that belief. The purpose of this study was to examine the relationships of ST on memory performance in older adults over 24 months. The ST levels on average significantly declined, or improved in the memory training, but not the health training group. Although not significant at the .01 level, the bivariate correlation indicated that change in ST was moderately related to change in verbal memory, suggesting the possibility that improvements (or reductions) in ST may be related to increases in verbal memory scores. We discovered that the unique contribution of ST into the memory performance of healthy older adults offers a possible malleable trait.

AbstractAlterations of resting-state EEG microstates have been associated with various neurological disorders and behavioral states. Interestingly, age-related differences in EEG microstate organization have also been reported, and it has been suggested that resting-state EEG activity may predict cognitive capacities in healthy individuals across the lifespan. In this exploratory study, we performed a microstate analysis of resting-state brain activity and tested allocentric spatial working memory performance in healthy adult individuals: twenty 25–30-year-olds and twenty-five 64–75-year-olds. We found a lower spatial working memory performance in older adults, as well as age-related differences in the five EEG microstate maps A, B, C, C′ and D, but especially in microstate maps C and C′. These two maps have been linked to neuronal activity in the frontal and parietal brain regions which are associated with working memory and attention, cognitive functions that have been shown to be sensitive to aging. Older adults exhibited lower global explained variance and occurrence of maps C and C′. Moreover, although there was a higher probability to transition from any map towards maps C, C′ and D in young and older adults, this probability was lower in older adults. Finally, although age-related differences in resting-state EEG microstates paralleled differences in allocentric spatial working memory performance, we found no evidence that any individual or combination of resting-state EEG microstate parameter(s) could reliably predict individual spatial working memory performance. Whether the temporal dynamics of EEG microstates may be used to assess healthy cognitive aging from resting-state brain activity requires further investigation.

AbstractMaintenance of information in working memory (WM) is assumed to rely on refreshing and elaboration, but clear mechanistic descriptions of these cognitive processes are lacking, and it is unclear whether they are simply two labels for the same process. This fMRI study investigated the extent to which refreshing, elaboration, and repeating of items in WM are distinct neural processes with dissociable behavioral outcomes in WM and long-term memory (LTM). Multivariate pattern analyses of fMRI data revealed differentiable neural signatures for these processes, which we also replicated in an independent sample of older adults. In some cases, the degree of neural separation within an individual predicted their memory performance. Elaboration improved LTM, but not WM, and this benefit increased as its neural signature became more distinct from repetition. Refreshing had no impact on LTM, but did improve WM, although the neural discrimination of this process was not predictive of the degree of improvement. These results demonstrate that refreshing and elaboration are separate processes that differently contribute to memory performance.HighlightsRepeated reading, refreshing, and elaboration are differentiable in brain activation patterns in both young and older adults.Elaboration selectively improved long-term memory for young adults, and the size of the benefit was related to the neural separability of elaboration from other processes.Older adults implemented a sub-optimal form of elaboration, and this may be a factor contributing to age-related deficits in long-term memory.Ethics statementThe study was approved by the ethical review board of the canton of Zurich (BASEC-No. 2017-00190) and all subjects gave informed written consent in accordance with the Declaration of Helsinki.Data and code availability statementAll behavioral data and analysis scripts can be assessed on the Open Science Framework (osf.io/p2h8b/).

Abstract Age-based stereotype threat (ABST) occurs when older adults are influenced by negative stereotypes about age-related decline and functional losses and ironically behave in disengaging and self-defeating ways that confirm the stereotype (Steele & Aronson, 1995). Aging stereotypes are found to be strong predictors of health and illness outcomes in later life, and are associated with performance in specific areas, mainly in cognitive and physical domains. The current study reviewed the experimental methods and their reported effects previously published in the literature to determine if there were different ABST methods were associated with different types of age-related outcomes. We conducted a systematic review, screening the scientific literature for papers that included experimental manipulation of age-related stereotypes as an independent variable, focusing on samples of older adults (1113 articles, most published after 2003). Through a classification of the common and distinctive characteristics of the different stereotype manipulation techniques, we were able to identify three specific types of experimental methods: by instruction, tests, and interpersonal exposure. Although the mechanism by which stereotypes are associated with functional outcomes in older adults remains unclear, our review suggests it is possible to experimentally control the activation of the stereotype by manipulating its specific characteristics and the way older participants are exposed to it. Findings also highlight the possibility that specific experimental methods used to induce ABST in older individuals may lead to unique and different consequences on functional performance variation.
