Age-related mobility research often highlights significant mobility differences comparing neurotypical young and older adults, while neglecting to report mobility outcomes for middle-aged adults. Moreover, these analyses regularly do not determine which measures of mobility can discriminate groups into their age brackets. Thus, the current study aimed to provide a comprehensive analysis for commonly performed aspects of mobility (walking, turning, sit-to-stand, and balance) to determine which variables were significantly different and furthermore, able to discriminate between neurotypical young adults (YAs), middle-aged adults (MAAs), and older adults (OAs). This study recruited 20 YAs, 20 MAAs, and 20 OAs. Participants came into the laboratory and completed mobility testing while wearing wireless inertial sensors. Mobility tests assessed included three distinct two-minute walks, 360° turns, five times sit-to-stands, and a clinical balance test, capturing 99 distinct mobility metrics. Of the various mobility tests assessed, only 360° turning measures demonstrated significance between YAs and MAAs, although the capacity to discriminate between groups was achieved for gait and turning measures. A variety of mobility measures demonstrated significance between MAAs and OAs, and furthermore discrimination was achieved for each mobility test. These results indicate greater mobility differences between MAAs and OAs, although discrimination is achievable for both group comparisons.

Abstract Objective We conducted a cross-sectional study to examine age-¬related differences in performance on a new test assessing memory for “who, when, and where” and associations among these elements. The test was designed to assess aspects of episodic memory by simulating an everyday experience of meeting a series of different people in different places across time. Method Healthy young (ages 18¬-25), middle-aged (ages 40-55), and older adults (ages 60+) were asked to remember a sequence of pictures of different faces paired with different places. After viewing the sequence, the participants were asked to pair each face with the correct place and put the face-place pairs in the correct sequence. Participants also completed a battery of standardized neuropsychological tests. Results Young adults remembered significantly more face-place pairs in the correct sequence than middle-aged (p < .05) and older adults (p < .05). There were no significant differences between middle-aged and older adults in the number of face-place pairs in correct sequence. Furthermore, young adults remembered significantly more face-place pairs irrespective of sequence than older adults (p < .05). There were no significant differences between young and middle-aged adults or between middle-aged and older adults in the number of correct face-place pairs irrespective of sequence. Conclusions Using a new test that incorporates aspects of episodic memory, we found evidence for age-related differences in test performance beginning in middle age. We found that performance on the test correlated with performance on standardized measures of verbal memory and executive functioning but not visual confrontation naming.

Abstract Attitudes towards aging include both positive and negative beliefs about older adults (Iverson et al., 2017; Palmore, 1999). Palmore’s (1998) Facts on Aging Quiz, a widely used assessment of knowledge about aging, also identifies common societal misconceptions about aging. Findings regarding age group differences in attitudes toward aging are mixed (Bodner et al., 2012; Cherry & Palmore, 2008; Rupp et al., 2005). The current study compared knowledge of aging, negative age bias, and positive age bias between young adults (18-35 years, n=268) and middle-aged adults (40-55 years; n=277). Middle-aged adults reported significantly greater average knowledge of aging than young adults (p=.019), although both groups had relatively low knowledge (MA: M=13.0, YA: M=12.2). Middle-aged adults also showed significantly less negative age bias (p&lt;.001) and significantly more positive age bias than young adults (p=.026). Although the total sample was significantly more likely to be incorrect than correct on 23 of the 25 facts (p&lt;.001), young adults were significantly more likely than middle-aged adults (p&lt;.001) to respond incorrectly for only 2 of 25 facts. Both facts reflected greater negative age bias among young adults than middle-aged adults. These facts concerned older adults’ ability to work as effectively as young adults (fact 9) and frequency of depression in older adults (fact 13). Results demonstrate that age bias is not limited to young adults and may continue through midlife, though negative age bias in particular may be lower for individuals approaching older adulthood, which could have implications for their psychological and physical well-being.

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.

: Sustained attention (SA) is a construct of cognition that tends to decline with age. There is a lack of literature regarding the neural correlates of SA in middle age, a link between young and old age. This study evaluated the differences in SA ability and its neural correlates using functional near-infrared spectroscopy (fNIRS) between young and middle-aged adults. 38 young and 25 middle-aged adults were evaluated for the changes in neural correlates (oxy and deoxyhemoglobin concentration in the prefrontal cortex) during a SA task known as cognition. The results showed that young adults performed significantly better than middle-aged adults on the SA task with no gender difference in their performance. There was a significant difference in the prefrontal activation pattern between young and middle-aged adults. We found right prefrontal dominance in young adults and left the prefrontal authority in middle-aged adults. This study concludes that the ability to maintain SA diminishes with age, advancing from young to middle age. Hemodynamic findings confirmed significant differences in neural resources in the prefrontal cortical areas between young and middle age. Findings document the neurobiological basis of age-related decline in the middle-aged population to understand changes in the brain's functioning during SA-related cognitive tasks.

The Relationship

The aim of this study is to analyze the mediating role of vision in the relationship between conscious lower limb proprioception (dominant knee) and bipedal postural control (with eyes open and closed) in older adults, as compared with teenagers, younger adults and middle-aged adults. Methods: The sample consisted of 119 healthy, physically active participants. Postural control was assessed using the bipedal Romberg test with participants’ eyes open and closed on a force platform. Proprioception was measured through the ability to reposition the knee at 45°, measured with the Goniometer Pro application’s goniometer. Results: The results showed an indirect relationship between proprioception and postural control with closed eyes in all age groups; however, vision did not mediate this relationship. Conclusions: Older adults outperformed only teenagers on the balance test. The group of older adults was the only one that did not display differences with regard to certain variables when the test was done with open or closed eyes. It seems that age does not influence performance on proprioception tests. These findings help us to optimize the design of training programs for older adults and suggest that physical exercise is a protective factor against age-related decline.

Perceptions of the entitativity of age groups, cohorts, and generations were studied in a sample of young adults. Participants rated one of three age groups (young adults, middle-aged adults, older adults), described either as generations (e.g., Baby Boom generation), by age (e.g., people 50 years old), or as cohorts (e.g., people born between 1945 and 1950). Ratings were made on entitativity and related properties (importance of membership to members, shared experience, common goals, common values, similarity among members). Results show that age groups and generations are meaningful social categories for laypersons, whereas cohorts are not.

Peak Speed

Purpose To improve our understanding about the underlying factors of aging-related speaking rate decline, the authors sought to determine if lip and jaw speeds are physiologically constrained in older adults. Method Thirty-six females—10 young adults (ages 22–27 years), 9 middle-aged adults (ages 45–55 years), 10 young-old adults (65–74 years), and 7 very old adults (ages 87–95 years)—completed metronome-paced syllable repetitions while moving the lower lip or jaw to a fixed target with each repetition. Metronome paces incrementally increased from 1.4 Hz to 6.7 Hz. Lip and jaw movements were tracked using a 3-dimensional motion capture system. Results Older adults' maximum percent increase in lip and jaw peak speed was comparable to or tended to be even greater than that of middle-aged and young adults. By contrast, lip and jaw stiffness, indexed by peak speed–displacement ratios, tended to decrease with age during fast and very fast repetition rates and were associated with mildly prolonged movement durations. Conclusions The findings suggest that lip and jaw speeds are not constrained in older adults. The trend of reduced stiffness during fast rates, however, suggests that fine-force regulation becomes difficult for older adults. Thus, older adults may implement reduced habitual speaking rates as a behavioral strategy to compensate for diminished articulatory control.
