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.

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.

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.

Perspective Switching

In the Dot task, children and adults involuntarily compute an avatar’s visual perspective, which has been interpreted as automatic Theory of Mind. We conducted three experiments in India, testing newly sighted children (N=5; all girls), neurotypical children (ages 5-10; N=90; 38 girls) and adults (N=30; 18 women) in a highly simplified version of the Dot task. No evidence of automatic perspective-taking was observed, although all groups revealed perspective-taking costs. A newly sighted child and the youngest children in our sample also showed an egocentric bias, which disappeared by age 10. Responding to recent work on what Theory of Mind tasks actually measure, we conclude that the standard Dot task relies so heavily on Executive Control that the alleged evidence of automatic Theory of Mind might simply reveal perspective switching costs.

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.

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.

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.

Referential Choice

A prevalent finding in the referential communication literature is that older adults produce more ambiguous pronouns than younger adults, likely because they have difficulty determining the prominence of referents. This finding has been widely understood to reflect a general age-related deficit in communication. However, all studies from this line of work have used materials involving topic shifts (i.e. when the to-be-named referent shifts from one character to another, which requires perspective-taking and can be cognitively costly). To determine the extent to which younger and older adults’ pronominal use diverges, we investigated whether other aspects of the discourse context influence age-related differences in referential choice, apart from topic shifts. Here we tested a large sample of adults (N=496, ages 18-82) using narrative elicitation tasks across four experiments and nine contexts of topic continuity (i.e. contexts in which the to-be-named referent remained the same). In Experiments 1 and 2, we varied the number of characters in the scene while keeping the sex/gender of the characters distinct and found that pronominal use did not differ by age for scenes with 1, 2, and 3 characters. In Experiments 3 and 4, we varied the number of characters, the sex/gender of those characters (such that they were the same or different), and the linguistic emphasis placed on the main character. Again, we found no age differences across all conditions. Taken together, our findings suggest that older adults’ difficulty with prominence estimates is not all- encompassing, but rather appears to be confined to contexts involving topic shifts.

Introduction Embodiment involves experiencing ownership over our body and localizing it in space and is informed by multiple senses (visual, proprioceptive and tactile). Evidence suggests that embodiment and multisensory integration may change with older age. The Virtual Hand Illusion (VHI) has been used to investigate multisensory contributions to embodiment, but has never been evaluated in older adults. Spatio-temporal factors unique to virtual environments may differentially affect the embodied perceptions of older and younger adults. Methods Twenty-one younger (18–35 years) and 19 older (65+ years) adults completed the VHI paradigm. Body localization was measured at baseline and again, with subjective ownership ratings, following synchronous and asynchronous visual-tactile interactions. Results Higher ownership ratings were observed in the synchronous relative to the asynchronous condition, but no effects on localization/drift were found. No age differences were observed. Localization accuracy was biased in both age groups when the virtual hand was aligned with the real hand, indicating a visual mislocalization of the virtual hand. Conclusions No age-related differences in the VHI were observed. Mislocalization of the hand in VR occurred for both groups, even when congruent and aligned; however, tactile feedback reduced localization biases. Our results expand the current understanding of age-related changes in multisensory embodiment within virtual environments.

Increasing the amount of physical activity (PA) in older adults that have shifted to a sedentary lifestyle is a determining factor in decreasing health and social costs. It is, therefore, imperative to develop objective methods that accurately detect daily PA types and provide detailed PA guidance for healthy aging. Most of the existing techniques have been applied in the younger generation or validated in the laboratory. To what extent, these methods are transferable to real-life and older adults are a question that this paper aims to answer. Sixty-three participants, including 33 younger and 30 older healthy adults, participated in our study. Each participant wore five devices mounted on the left and right hips, right knee, chest, and left pocket and collected accelerometer and GPS data in both semi-structured and real-life environments. Using this dataset, we developed machine-learning models to detect PA types walking, non-level walking, jogging/running, sitting, standing, and lying. Besides, we examined the accuracy of the models within-and between-age groups applying different scenarios and validation approaches. The within-age models showed convincing classification results. The findings indicate that due to age-related behavioral differences, there are more confusion errors between walking, non-level walking, and running in older adults’ results. Using semi-structured training data, the younger adults’ models outperformed older adults’ models. However, using real-life training data alone or in combination with semi-structured data generated better results for older adults who had high real-life data quality. Assessing the transferability of the models to older adults showed that the models trained with younger adults’ data were only weakly transferable. However, training the models with a combined dataset of both age groups led to reliable transferability of results to the data of the older subgroup. We show that age-related behavioral differences can alter the PA classification performance. We demonstrate that PA type detection models that rely on combined datasets of young and older adults are strongly transferable to real-life and older adults’ data. Our results yield significant time and cost savings for future PA studies by reducing the overall volume of training data required.
