Should older people be considered a homogeneous group when interacting with level 3 automated vehicles?

Exploring the future mobility of older people is imperative for maintaining wellbeing and quality of life in an ageing society. The forthcoming level 3 automated vehicle may potentially benefit older people. In a level 3 automated vehicle, the driver can be completely disengaged from driving while, under some circumstances, being expected to take over the control occasionally. Existing research into older people and level 3 automated vehicles considers older people to be a homogeneous group, but it is not clear if different sub-groups of old people have different performance and perceptions when interacting with automated vehicles. To fill this research gap, a driving simulator investigation was conducted. We adopted a between-subjects experimental design with subgroup of old age as the independent variable. The differences in performance, behaviour, and perception towards level 3 automated vehicles between the younger old group (60–69 years old) and older old group (70 years old and over) was investigated. 15 subjects from the younger old group (mean age = 64.87 years, SD = 3.46 years) and 24 from the older old group (mean age = 75.13 years, SD = 3.35 years) participated in the study. The findings indicate that older people should not be regarded as a homogeneous group when interacting with automated vehicle. Compared to the younger old people, the older old people took over the control of the vehicle more slowly, and their takeover was less stable and more critical. However, both groups exhibited positive perceptions towards level 3 automation, and the of older old people’s perceptions were significantly more positive. This study demonstrated the importance of recognising older people as a heterogeneous group in terms of their performance, capabilities, needs and requirements when interacting with automated vehicles. This may have implications in the design of such systems and also understanding the market for autonomous mobility.     

Psychological and socioeconomic health of community‐dwelling older adults

Different dimensions of health are intertwined. The purposes of this study were: (1) to investigate the psychological and socioeconomic health status of community‐dwelling older adults in Taiwan, and (2) to compare the psychological and socioeconomic health differences among people of different age groups, gender, marital status, and exercise habits. Using stratified random sampling, 384 Taiwanese community‐dwelling older adults were recruited for this survey research. Based on the Health Model of Older Adults, seven constructs were measured: (1) psychological health: sleep quality, emotional health, cognitive functioning, and health promotion behaviors; (2) socioeconomic health: social engagement, social support, and financial status. Results showed that most participants were in a good state of psychological and socioeconomic health, except that 38.02% of them suffered from sleep disruptions, and the majority of them were not involved in any social group, nor engaged in any volunteer work. Young‐old older adults had better psychological and socioeconomic health than middle‐old and old‐old older adults. Male older adults had better psychological health than female older adults; however, they had less social engagement and social support than female older adults. Married older adults and exercisers performed better in most of the psychological and socioeconomic health indicators than single/widowed older adults and non‐exercisers.     

Stronger evidence for own-age effects in memory for older as compared to younger adults

Three studies examined whether younger and older adults better recall information associated with their own than information related to another age group. All studies compared young and older adults with respect to incidental memory for previously presented stimuli (Studies 1 and 2: everyday objects; Study 3: vacation advertisements) that had been randomly paired with an age-related cue (e.g., photo of a young or an old person; the word "young" or "old"). All three studies found the expected interaction of participants' age and age-associated information. Studies 1 and 2 showed that the memory bias for information arbitrarily associated with one's own as compared to another age group was significant for older adults only. However, when age-relevance was introduced in a context of equal importance to younger and older adults (information about vacations paired either with pictures of young or older adults), the memory bias for one's own age group was clearly present for both younger and older adults (Study 3).     

Age differences in proactive interference, working memory, and abstract reasoning

It has been hypothesized that older adults are especially susceptible to proactive interference (PI) and that this may contribute to age differences in working memory performance. In young adults, individual differences in PI affect both working memory and reasoning ability, but the relations between PI, working memory, and reasoning in older adults have not been examined. In the current study, young, old, and very old adults performed a modified operation span task that induced several cycles of PI buildup and release as well as two tests of abstract reasoning ability. Age differences in working memory scores increased as PI built up, consistent with the hypothesis that older adults are more susceptible to PI, but both young and older adults showed complete release from PI. Young adults' reasoning ability was best predicted by working memory performance under high PI conditions, replicating M. Bunting (2006). In contrast, older adults' reasoning ability was best predicted by their working memory performance under low PI conditions, thereby raising questions regarding the general role of susceptibility to PI in differences in higher cognitive function among older adults.

Children's perceptions of and beliefs about facial maturity

The author studied children's and young adult's perceptions of facial age and beliefs about the sociability, cognitive ability, and physical fitness of adult faces. From pairs of photographs of adult faces, participants (4-6 years old, 8-10 years old, 13-16 years old, and 19-23 years old) selected the one face that appeared younger, older, better at remembering, smarter, more caring, friendlier, healthier, or stronger. Pairings consisted of faces at different adult age levels (young adults, middle-age adults, older adults, and very old adults.) Older participants were more sensitive to age differences in older faces and to faces more proximal in age. Children and adolescents believed that very old adult faces appeared to be less cognitively able than middle-aged faces (for children) and young adult faces (for adolescents). Very old male faces were judged to be less sociable. Old and very old faces were judged to be less physically fit than young and middle-aged faces. Significant positive correlation coefficients were found between the youngest children's abilities to discriminate between the adult faces of proximal age and youthful biases when selecting faces appearing to be more sociable and cognitively able. The results are discussed with respect to the development of facial information-processing skills and how those skills may be associated with the development of and changes in beliefs about older adults.

Age, marital satisfaction, and optimism as predictors of positive sentiment override in middle-aged and older married couples

This study examined whether positive sentiment override (greater positive appraisal of spouse's affiliative behavior than is warranted by observed behavior) occurred more frequently in older compared with middle-aged married couples and whether age differences were mediated by older adults' greater marital satisfaction when controlling for optimism. Participants included 270 middle-aged (40-50 years old) and older (60-70 years old) couples who discussed a marital disagreement and completed an errand task. Couples provided appraisals of their spouse's affiliation, and the authors coded affiliative interactions using the structural analysis of social behavior. Hierarchical multivariate linear modeling indicated that older husbands and wives viewed their spouse's behavior as more positive during disagreement interactions than did independent observers; in the errand task, only older wives demonstrated positive sentiment override. Age differences in positive sentiment override were mediated by marital satisfaction, even when controlling for optimism. The results are consistent with theories of emotion regulation, such as socioemotional selectivity theory, that suggest that older adults are biased toward the positive aspects of close relationships.     

Developmental Characteristics of Disparate Bimanual Movement Skills in Typically Developing Children

Mastery of many tasks in daily life requires role differentiated bimanual hand use with high spatiotemporal cooperation and minimal interference. The authors investigated developmental changes in the performance of a disparate bimanual movement task requiring sequenced movements. Age groups were attributed to changes in CNS structures critical for bimanual control such as the corpus callosum (CC) and the prefrontal cortex; young children (5–6 years old), older children (7–9 years old), and adolescents (10–16 years old). Results show qualitative changes in spatiotemporal sequencing between the young and older children which typically marks a phase of distinct reduction of growth and myelination of the CC. Results show qualitative changes in spatiotemporal sequencing between the young and older children, which coincides with distinct changes in the growth rate and myelination of the CC. The results further support the hypothesis that CC maturation plays an important role in the development of bimanual skills.     

Ältere Menschen als Zeugen vor Gericht

This article provides an overview of the current empirical literature concerning older adults as eyewitnesses. Aging affects perception, memory and eyewitness testimony in many older adults (aged 65 years and above). As a group, they provide shorter accounts in free call, fewer correct and more incorrect details. Often they have to be asked more questions than young witnesses in order to obtain the same amount of information. Age differences have also been demonstrated for answers to questions. There are some promising attempts to improve older witnesses’ testimony, such as the Cognitive Interview. However, replication studies are still needed here. It remains unclear if older witnesses are generally more vulnerable to suggestions than young witnesses. There is some evidence that at least in some situations this seems to be the case. In photographic line-ups young and older adults show similar positive identification rates, but older adults have higher false alarm rates. When viewing mug books, older adults are more likely to make a choice than young adults, which can lead to higher rates of possibly false identification in a subsequent line-up. With increasing age age differences between young and old witnesses also increase. However there is considerable interindividual variation in witness performance: some witnesses are impacted by age early-on, while others remain highly functioning until very old age.     

Crones, Dirty Old Men, Sexy Seniors: Representations of the Sexuality of Older Persons

The representations of the sexuality of older persons in American society are neither flattering nor accurate. Often what is presented is filled with confusion, uncertainty, and contradictions. Sexuality of old people, like sexuality of adolescents, frightens most adults in between. Evidence suggests hope that in popular culture, conventional representations of sexless older people are finally undergoing a change. The popular literature aimed at elderly or midlife audiences increasingly portrays older persons as healthy, vigorous, and not unattractive. Since in the popular mind attractiveness and sexuality are believed to be closely linked, this change signals an increased willingness to credit old people who are aging well (i.e., who look and act young) with being sexually interested and probably active.     

Psyche and eros

This article addresses concerns and needs as one approaches old age. The beauty of being old is what one has discarded and what one has kept. Jung's idea of the opposites is explored as well as the need to reconcile them as one gets older. Examples of men and women attempting to accept the fate of being old illustrate the author's main theme that beauty resides in the reconciliation of the ego taking a new and less dominant position in relation to the Self.

Understanding age-related reductions in visual working memory capacity: Examining the stages of change detection

Visual working memory (VWM) capacity is reduced in older adults. Research has shown age-related impairments to VWM encoding, but aging is likely to affect multiple stages of VWM. In the present study, we recorded the event-related potentials (ERPs) of younger and older adults during VWM maintenance and retrieval. We measured encoding-stage processing with the P1 component, maintenance-stage processing with the contralateral delay activity (CDA), and retrieval-stage processing by comparing the activity for old and new items (old–new effect). Older adults showed lower behavioral capacity estimates (K) than did younger adults, but surprisingly, their P1 components and CDAs were comparable to those of younger adults. This remarkable dissociation between neural activity and behavior in the older adults indicated that the P1 and CDA did not accurately assess their VWM capacity. However, the neural activity evoked during VWM retrieval yielded results that helped clarify the age-related differences. During retrieval, younger adults showed early old–new effects in frontal and occipital areas and a late central–parietal old–new effect, whereas older adults showed a late right-lateralized parietal old–new effect. The younger adults’ early old–new effects strongly resembled an index of perceptual fluency, suggesting that perceptual implicit memory was activated. The activation of implicit memory could have facilitated the younger adults’ behavior, and the lack of these early effects in older adults may suggest that they have much lower-resolution memory than do younger adults. From these data, we speculated that younger and older adults store the same number of items in VWM, but that younger adults store a higher-resolution representation than do older adults.     

Developmental changes in the recognition of faces and facial features

The view that, as children get older, there is a decline in the use of feature‐based forms of face processing to more configurational forms of processing was examined by asking 6‐year‐old and 9‐year‐old children to judge which of two photographs matches an identical probe photograph. The probe and test stimuli were either photographs of whole faces or photographs of isolated facial features. Within this standard method, the stimuli also systematically varied in terms of the familiarity of the faces shown and in the orientation of presentation, both factors that have been interpreted as effecting configurational encoding. A number of age‐related effects are observed: (a) older children are better at recognizing whole faces than younger children, (b) older children exhibit a clear face inversion effect with whole faces while the younger children are equally adept at identifying upright and inverted whole faces, and (c) analysis of the recognition rates associated with the individual features reveals that younger children are better than older children when asked to recognize eye regions. It is argued that the data support the view that as children get older there is a change in the forms of piecemeal encoding employed and an increase in configurational processing.

Effects of repetition on associative recognition in young and older adults: item and associative strengthening

Young and older adults studied word pairs and later discriminated studied pairs from various types of foils including recombined word-pairs and foil pairs containing one or two previously unstudied words. We manipulated how many times a specific word pair was repeated (1 or 5) and how many different words were associated with a given word (1 or 5) to tease apart the effects of item familiarity from recollection of the association. Rather than making simple old/new judgments, subjects chose one of five responses: (a) Old-Old (original), (b) Old-Old (rearranged), (c) Old-New, (d) New-Old, (e) New-New. Veridical recollection was impaired in old age in all memory conditions. There was evidence for a higher rate of false recollection of rearranged pairs following exact repetition of study pairs in older but not younger adults. In contrast, older adults were not more susceptible to interference than young adults when one or both words of the pair had multiple competing associates. Older adults were just as able as young adults to use item familiarity to recognize which word of a foil was old. This pattern suggests that recollection problems in advanced age are because of a deficit in older adults' formation or retrieval of new associations in memory. A modeling simulation provided good fits to these data and offers a mechanistic explanation based on an age-related reduction of working memory.     

How Effective is the Enhanced Cognitive Interview when Aiding Recall Retrieval of Older Adults including Memory for Conversation?

The percentage of older adults in the general population is growing. As a result, older adults are coming more frequently into contact with the Criminal Justice System as witnesses to and victims of crime. Older adults are also over‐represented in crimes where conversation detail is of particular importance to an investigation (e.g. distraction burglary). The present study therefore examined the efficacy of cognitive interview (CI) compared with structured interview in improving the recall of an event by older witnesses, specifically conversational detail. Young adults (19–54 years old), young‐old adults (60–74 years old), and old‐old adults (75+ years old) were asked to watch a short film of a laptop theft and were then, after a 1.5 hour delay, randomly allocated to one of two interview conditions. It was found that the CI significantly increased recall of all age groups, without increasing the amount of incorrect or confabulated information reported. The individuals in the young adult and the young‐old adult conditions were found to remember significantly more than the individuals from the old‐old adult condition, without decreasing the accuracy of the information. The CI enhanced memory for conversation gist, person and action detail. Results will be discussed in relation to interviewing and investigating practices.

Below the Age of Consent: Influences on Moral and Legal Judgments of Adult–Adolescent Sexual Relationships1

Sexual age‐of‐consent violations involving adult–adolescent relationships (AARs) are sometimes viewed with ambivalence by the media and are infrequently prosecuted. Two studies conducted in Britain (where the age of consent is 16) examined influences on disapproval of minimally presented AARs between a 14‐year‐old and a 30‐year‐old. In Study 1, AARs involving an older man were seen as more harmful and objectionable than those involving an older woman. A second study on a jury‐eligible adult population replicated Study 1's gender effects, and also found a difference between legal knowledge and personal belief that the older person had committed a crime. Gender effects in both studies were mediated by perceived harm and emotions.     

The older patient in psychoanalysis

The demographic shift toward extended longevity has led to a commensurate increase in the length of the working and productive years, and with it an increase in the number of so-called "older" patients who come into psychoanalysis or psychoanalytic psychotherapy. This led the Psychoanalytic Research and Development Fund to support a four-year study by a small group of experienced psychoanalysts of "the older patient in psychoanalysis." Aging and old age are considered to be the final developmental crisis of the successive epigenetic phases of the life cycle. Eleven case presentations and various briefer clinical vignettes informed us that older and even old individuals, who seek treatment themselves or who are appropriately referred, respond in a positive and effective fashion to psychoanalysis and psychoanalytic psychotherapy. As do younger patients in analysis, such older people, motivated by the wish to make the most of what time is left, become interested in understanding their pasts with respect to the present and the future. The life stories of two older men who undertook analysis, and the courses and outcomes of their analyses, illustrate our findings and impressions. In both cases conflicts and difficulties from earlier developmental phases, extending back even as far as the oedipal and preoedipal years, were revived during their older years. And although these conflicts might have been beyond definitive resolution, what is salient is the extent to which they were ameliorated: sufficiently that they did not impede a satisfactory adaptive solution of the final crisis of the normative sequences of the life cycle.

Attitude and personality characteristics of older stutterers

Attitude and personality characteristics of 29 stutterers (19 male, 10 female) aged 52–82 yr were assessed using five questionnaires. Results indicate that, while the older stutterers score approximately the same as young adult stutterers on scales assessing approach and performance behaviors, the large majority of older stutterers perceive their stuttering as less handicapping than when they were young adults. Self-perceived personality characteristics of the older stutterers were similar to a group of older nonstutterers. While a few of the subjects had experienced some degree of success as a result of treatment later in life, the majority of the subjects did not currently desire treatment.
