Linking individual differences in cognitive control and perception: Meta-perception in older and younger adults

Visual perception is not only shaped by sensitivity, but also by confidence, i.e. the ability to estimate the accuracy of a visual decision. There is robust evidence that younger observers have access to a reliable measure of their own uncertainty when making visual decisions. This metacognitive ability might be challenged during aging due to increasing sensory noise and decreasing cognitive control resources. We investigated age effects on visual confidence using a confidence forced-choice paradigm. We determined discrimination thresholds for trials in which perceptual judgements were indicated as confident and for those in which they were declined as confident. Younger adults (19-38 years) showed significantly lower discrimination thresholds than older adults (60-78 years). In both age groups, perceptual performance was linked to confidence judgements, but overall results suggest reduced confidence efficiency in older adults. However, we observed substantial variability of confidence effects across all particpants. This variability was closely linked to individual differences in cognitive control capacities, i.e. executive function. Our findings provide evidence for age-related differences in meta-perceptual efficiency that present a specific challenge to perceptual performance in old age. We propose that these age effects are primarily mediated by cognitive control resources, supporting their crucial role for metacognitive efficiency.

Positive Memories

Abstract Centrality of an event (CE) is a characteristic denoting how important a life experience is to one’s identity. Usually, positive memories are more central than negative ones in the community samples. Nevertheless, there is emerging evidence showing substantial individual differences in how one perceives CE. Especially regarding age, one could expect pronounced differences due to age-related changes in personal goals. In this study, we investigated how older adults differ from young and middle-aged adults. Apart from age, we tested whether personality traits such as neuroticism and openness to experience influence the CE ratings among age groups. The sample comprised of 363 German participants, age ranging from 18 to 89 (M=49.57, SD=17.087), 67.2 % of the sample were women. Using multilevel analysis, we found the CE of positive memories to be higher in all age groups. The CE of positive events significantly differed for older adults compared to younger adults but not to the middle-aged group. With respect to personality, neuroticism had an impact only on the CE of negative memories in younger and middle-aged adults. For older adults, neither neuroticism, nor openness to experience had an impact on CE ratings. This shows that while older adults significantly differ from younger adults in the CE of positive memories, other individual differences characteristics do not have an impact on the way older adults perceive memories as central to their identity.

Effects Of Aging

Abstract Objective The Face-Name Associative Memory test (FNAME) has recently received attention as a test for early diagnosis of Alzheimer’s disease. So far, however, there has been no systematic investigation of the effects of aging. Here, we aimed to assess the extent to which the FNAME performance is modulated by normal ageing. Method In a first step, we adapted the FNAME material to the Dutch population. In a second step, younger (n = 29) and older adults (n = 29) were compared on recall and recognition performance. Results Significant age effects on name recall were observed after the first exposure of new face-name pairs: younger adults remembered eight, whereas older adults remembered a mean of four out of twelve names. Although both age groups increased the number of recalled names with repeated face-name exposure, older adults did not catch up with the performance of the younger adults, and the age-effects remained stable. Despite of that, both age groups maintained their performance after a 30-min delay. Considering recognition, no age differences were demonstrated, and both age groups succeeded in the recognition of previously shown faces and names when presented along with distractors. Conclusions This study presents for the first time the results of different age groups regarding cross-modal associative memory performance on the FNAME. The recall age effects support the hypothesis of age-related differences in associative memory. To use the FNAME as an early cognitive biomarker, further subscales are suggested to increase sensitivity and specificity in the clinical context.

Cognitive Task Performance

Motivational incentives play an influential role in value-based decision-making and cognitive control. A compelling hypothesis in the literature suggests that the brain integrates the motivational value of diverse incentives (e.g., motivational integration) into a common currency value signal that influences decision-making and behavior. To investigate whether motivational integration processes change during healthy aging, we tested older (N=44) and younger (N=54) adults in an innovative incentive integration task paradigm that establishes dissociable and additive effects of liquid (e.g., juice, neutral, saltwater) and monetary incentives on cognitive task performance. The results reveal that motivational incentives improve cognitive task performance in both older and younger adults, providing novel evidence demonstrating that age-related cognitive control deficits can be ameliorated with sufficient incentive motivation. Additional analyses revealed clear age-related differences in motivational integration. Younger adult task performance was modulated by both monetary and liquid incentives, whereas monetary reward effects were more gradual in older adults and more strongly impacted by trial-by-trial performance feedback. A surprising discovery was that older adults shifted attention from liquid valence toward monetary reward throughout task performance, but younger adults shifted attention from monetary reward toward integrating both monetary reward and liquid valence by the end of the task, suggesting differential strategic utilization of incentives. Together these data suggest that older adults may have impairments in incentive integration, and employ different motivational strategies to improve cognitive task performance. The findings suggest potential candidate neural mechanisms that may serve as the locus of age-related change, providing targets for future cognitive neuroscience investigations.

Conditioned Responses

Older adults typically remember more positive than negative information compared to their younger counterparts; a phenomenon referred to as the ‘positivity effect.’ According to the socioemotional selectivity theory (SST), the positivity effect derives from the age-related motivational shift towards attaining emotionally meaningful goals which become more important as the perception of future time becomes more limited. Cognitive control mechanisms are critical in achieving such goals and therefore SST predicts that the positivity effect is associated with preserved cognitive control mechanisms in older adults. In contrast, the aging-brain model suggests that the positivity effect is driven by an age-related decline in the amygdala which is responsible for emotional processing and emotional learning. The aim of the current research was to address whether the age-related positivity effect is associated with cognitive control or impaired emotional processing associated with aging. We included older old adults, younger old adults and younger adults and tested their memory for emotional stimuli, cognitive control and amygdala-dependent fear conditioned responses. Consistent with prior research, older adults, relative to younger adults, demonstrate better memory for positive over negative images. We further found that within a group of older adults, the positivity effect increases as a function of age, such that older old adults demonstrated a greater positivity effect compared to younger older adults. Furthermore, the positivity effect in older old adults was associated with preserved cognitive control, supporting the prediction of SST. Contrary to the prediction of the aging-brain model, participants across all groups demonstrated similar enhanced skin conductance responses to fear conditioned stimuli – responses known to rely on the amygdala. Our results support SST and suggest that the positivity effect in older adults is achieved by the preserved cognitive control mechanisms and is not a reflection of the impaired emotional function associated with age.

Abstract Every day we use emotion words to describe our experiences, but past research finds that the meanings of these words can vary. Furthermore, historical shifts in language use and experiential knowledge of the emotions may contribute to age-differences in what these emotion words convey. We examined age-related differences in the valence, arousal, and expression connoted by the words anger, love, and sadness. We predicted age-related differences in the semantic meanings of the words would emerge such that older adults would more clearly differentiate the positivity/negativity of the words, whereas younger adults would report higher endorsement for the conveyed arousal and expression. Participants included American and German older adults (N=61; mean age=68.98) and younger adults (N=77; mean age=20.77). Using the GRID instrument (Swiss Center for Affective Sciences, 2013), they rated each emotion word for its valence, arousal, and expression when used by a speaker of the participant’s native language. Across emotions and dimensions, older adults were generally more moderate in their understanding of emotion words. For example, German older adults rated anger and sadness as suggesting the speaker felt less bad and more good than the younger adults. American older adults rated love as connoting the speaker felt more bad and less good than younger adults. Arousal ratings were higher for German younger, as opposed to older, adults. Cultural differences were most pronounced for sadness such that German participants gave more moderate answers than American participants. Overall, our research suggests that there are age-related differences in the understanding of emotion words.

Safe Product

Successful comprehension of warning text necessitates an ability to understand both explicitly stated safety information, as well as information about hazards and safe product usage that may be implied. Comprehension level for this type of text may vary across age groups as a function of normal age-related changes that may be experienced in memory and text comprehension in general. To date, there has been no comprehensive investigation of how well younger and older adults understand explicit and implicit information associated with actual product warnings. In the current study, 43 older and 42 younger adults read text from consumer product warnings and then rated the truth/falsity of statements containing information that was either explicitly stated or implied by the warnings. The results suggest both older and younger adults are able to recognize information that is explicitly associated with an actual product warning. However, they are less able to recognize information that can be inferred from warnings. These data also suggest that older adults perceive themselves to understand consumer warnings fairly well.

Listening In Noise ◽

Background: Age-related declines in auditory and cognitive processing may contribute to the difficulties with listening in noise that are often reported by older adults. Such difficulties are reported even by those who have relatively good audiograms that could be considered “normal” for their age (ISO 7029-2000 [ISO, 2000]). The Speech, Spatial, and Qualities of Hearing Scale (SSQ; Gatehouse and Noble, 2004) is a questionnaire developed to measure a listener's self-reported ability to hear in a variety of everyday situations, such as those that are challenging for older adults, and it can provide insights into the possible contributions of auditory and cognitive factors to their listening difficulties. The SSQ has been shown to be a sensitive and reliable questionnaire to detect benefits associated with the use of different hearing technologies and potentially other forms of intervention. Establishing how age-matched listeners with audiograms “normal” for their age rate the items on the SSQ could enable an extension of its use in audiological assessment and in setting rehabilitative goals. Purpose: The main purpose of this study was to investigate how younger and older adults who passed audiometric screening and who had thresholds considered to be “normal” for their age responded on the SSQ. It was also of interest to compare these results to those reported previously for older listeners with hearing loss in an attempt to tease out the relative effects of age and hearing loss. Study Sample: The SSQ was administered to 48 younger (mean age = 19 yr; SD = 1.0) and 48 older (mean age = 70 yr, SD = 4.1) adults with clinically normal audiometric thresholds below 4 kHz. The younger adults were recruited through an introductory psychology course, and the older adults were volunteers from the local community. Data Collection and Analysis: Both age groups completed the SSQ. The differences between the groups were analyzed. Correlations were used to compare the pattern of results across items for the two age groups in the present study and to assess the relationship between SSQ scores and objective measures of hearing. Comparisons were also made to published results for older adults with hearing loss. Results: The pattern of reported difficulty across items was similar for both age groups, but younger adults had significantly higher scores than older adults on 42 of the 46 items. On average, younger adults scored 8.8 (SD = 0.6) out of 10 and older adults scored 7.7 (SD = 1.2) out of 10. By comparison, scores of 5.5 (SD = 1.9) have been reported for older adults (mean age = 71 yr, SD = 8.1) with moderate hearing loss (Gatehouse and Noble, 2004). Conclusions: By establishing the best scores that could reasonably be expected from younger and older adults with “normal” hearing thresholds, these results provide clinicians with information that should assist them in setting realistic targets for interventions for adults of different ages.

Abstract The decline of working memory (WM) is a common feature of general cognitive decline, and visual and verbal WM capacity appear to decline at different rates with age. Visual material may be remembered via verbal codes or visual traces, or both. Souza and Skóra, Cognition, 166, 277–297 (2017) found that labeling boosted memory in younger adults by activating categorical visual long-term memory (LTM) knowledge. Here, we replicated this and tested whether it held in healthy older adults. We compared performance in silence, under instructed overt labeling (participants were asked to say color names out loud), and articulatory suppression (repeating irrelevant syllables to prevent labeling) in the delayed estimation paradigm. Overt labeling improved memory performance in both age groups. However, comparing the effect of overt labeling and suppression on the number of coarse, categorical representations in the two age groups suggested that older adults used verbal labels subvocally more than younger adults, when performing the task in silence. Older adults also appeared to benefit from labels differently than younger adults. In younger adults labeling appeared to improve visual, continuous memory, suggesting that labels activated visual LTM representations. However, for older adults, labels did not appear to enhance visual, continuous representations, but instead boosted memory via additional verbal (categorical) memory traces. These results challenged the assumption that visual memory paradigms measure the same cognitive ability in younger and older adults, and highlighted the importance of controlling differences in age-related strategic preferences in visual memory tasks.

Perspective Switching

One aspect of visual perspective taking (VPT) is the ability to switch between perspectives associated with self and others. Attenuated inhibition of the egocentric perspective is thought to underlie perspective taking difficulties in older adults leading to impaired social function. 117 adults (50 older adults 55-79 years; 67 young adults 18-36 years) completed two visual perspective taking tasks. The first task measured perspective tracking and required participants to understand what can be seen from the egocentric or allocentric perspective. The second measured perspective taking and required understanding how objects are seen from the egocentric or allocentric perspective. Both tasks involved trials that were congruent or incongruent between the two perspectives in order to assess how the other perspective interferes with the task-relevant perspective. Trials were further separated into those that required switching (preceding perspective was different to current) or sticking (preceding perspective was the same). We show an egocentric switch cost during perspective tracking in younger adults thought to reflect inhibition of the default egocentric perspective in the preceding trial. However, this effect was not identified in older adults. Moreover, older adults showed greater interference from their own perspective when required to stick with the allocentric perspective. No age differences were identified during perspective taking with both age groups showing an egocentric switch cost and an allocentric stick cost. The results provide evidence for age-related changes in VPT that are dependent on the requirement to switch or stick perspectives. Increased egocentricity in older adults is apparent but dependent on the switch-related context.

Engagement And Disengagement

Background: Although numerous studies have suggested that the gradually increasing selective preference for positive information over negative information in older adults depends on cognitive control processes, few have reported the characteristics of different attention stages in the emotional processing of older individuals. The present study used a real-time eye-tracking technique to disentangle the attentional engagement and disengagement processes involved in age-related positivity effect (PE).Methods: Eye movement data from a spatial-cueing task were obtained for 32 older and 32 younger healthy participants. The spatial-cueing task with varied cognitive loads appeared to be an effective way to explore the role of cognitive control during the attention engagement and disengagement stages of emotion processing.Results: Compared with younger adults, older participants showed more positive gaze preferences when cognitive resources were sufficient for face processing at the attention engagement stage. However, the age-related PE was not observed at the attention disengagement stage because older adults had more difficulty disengaging from fearful faces than did the younger adults due to the consumption of attention by the explicit target judgment.Conclusion: The present study highlights how cognitive control moderates positive gaze preferences at different attention processing stages. These findings may have far-reaching implications for understanding, preventing, and intervening in unsuccessful aging and, thus, in promoting active and healthy aging.
