Experience with Event Timing Does not Alter Emergent Timing: Further Evidence for Robustness of Event and Emergent Timing

Although, event and emergent timings are thought of as mutually exclusive, significant correlations between tapping and circle drawing (Baer, Thibodeau, Gralnick, Li, &; Penhune, 2013 Baer, L.

We aimed to test this hypothesis in both a younger (18–25) and older (55–100) population. Participants performed one block of circle drawing as a baseline, then six blocks of tapping, followed by circle drawing. We examined the use of event timing. Our hypothesis that acute experience with event timing would bias an individual to use event timing during an emergent task was not supported. We, instead, support the robustness of event and emergent timing as independent timing modes.     

Does a yellow filter improve visual object categorization in normal aging?

Previous studies have shown that a yellow filter (CPF450) can increase contrast, motion sensitivity, vergence, and accommodation. We investigated whether a yellow filter can reduce age-related visual deficits. We tested two groups of 60 observers (mean age 24 vs. 72) in an object categorization task. Grayscale photographs of natural objects and artifacts were displayed either centrally or peripherally (21°) at low (8%) or medium (30%) contrast. There were three filter conditions (no filter, placebo filter, and yellow filter). Both groups of observers performed similarly on central and medium-contrast pictures. The deleterious effects of reduced contrast and eccentricity were stronger in elderly individuals. Moreover, the yellow filter globally improved the speed of categorization for the elderly participants. The decrease in response time in the yellow filter condition was larger when the stimuli were displayed peripherally in both groups. A yellow filter should be considered as a potential means for visual improvement in normal aging.     

Sexual Health Risk Behaviors Among Older Men Who Have Sex With Men: Implications for Interventions

Sexual health risk behaviors, HIV and sexually transmitted infection (STI) transmission, substance use, stigma, and loneliness among older men who have sex with men are discussed. Implications for interventions are provided, including (a) assessment of health‐related risk behaviors, (b) brief interventions, (c) HIV and STI screening, and (d) relevant developmental and contextual factors.     

Narrative Practices and Positive Aging: A Reflection about Life Celebration in a Group of Old Women

The main objective of this article is to address the impact of narrative practices in life celebration after the age of 80 and in the co-construction of a community-positive future. We share here an exploratory reflection about the narratives of a group of older women integrated in a community project. The Wednesday Tea Project (Chá das Quartas) has been ongoing for 4 years, and involves a group of old women experiencing high levels of loneliness and isolation in their small village in Portugal. The Wednesday Tea Project is based on positive psychology methodologies and consists of ritualized sessions that encourage participatory group dynamics. To describe how this project has highlighted the benefits of narrative practices, we utilized a series of scaffolding questions. Some of the most relevant outcomes of this project are: (a) the deconstruction of the dominant social discourse; (b) the publication of a book; (c) the reduction of loneliness feelings by re-membering significant figures; and (d) new levels of action both to women and the community as a consequence of a re-authoring process. Narrative practices seem to have contributed to the consolidation of all time dimensions, giving these women the opportunity to celebrate life after the age of 80, while also allowing the community to be part of and to benefit from the process. A reflection about the contributions of this article to a paradigm change toward positive aging is presented.     

Working memory binding of visual object features in older adults

Accurate mental representation of visual stimuli requires retaining not only the individual features but also the correct relationship between them. This associative process of binding is mediated by working memory (WM) mechanisms. The present study re-examined reports of WM-related binding deficits with aging. In Experiment 1, 31 older and 31 younger adults completed a visual change detection task with feature–location relations presented either simultaneously or sequentially; the paradigm was also designed specifically to minimize the impact of lengthy retention intervals, elaborative rehearsal, and processing demands of multi-stimulus probes. In Experiment 2, 38 older and 42 younger adults completed a modified task containing both feature–location relations and feature–feature conjunctions. In Experiment 1 although feature–location binding was more difficult with sequential compared with simultaneous presentation, the effect was independent of age. In Experiment 2 while older adults were overall slower and less accurate than young adults, there were no age-specific deficits in WM binding. Overall, after controlling for methodological factors, there was no evidence of an age-related visual WM binding deficit for surface or location features. However, unlike younger adults, older adults appeared less able to restrict processing of irrelevant features, consistent with reported declines with age in strategic capacities of WM.     

Global cognitive function before,surrounding, and after ischemic stroke: the role of risk and protective factors varies with time among ischemic stroke survivors

An estimated 65% of individuals demonstrate multidomain cognitive impairment poststroke, although little is known about the varying role of cognitive risk and protective factors in preischemic, peri-ischemic, and postischemic stroke phases. Longitudinal changes in global cognitive function after ischemic stroke are not well characterized, especially in older adults over age 80. We examined global cognitive function trajectories in these three phases across a mean follow-up of 8.12 (2.30) years in 159 female stroke survivors aged 65–79 at baseline using linear mixed models with change points. In separate models controlling for demographic variables, we tested the interaction of baseline risk and protective factors with stroke phase on global cognitive function. None of the prestroke global cognitive function means or trajectories differed significantly. At the time of ischemic stroke, higher body mass index (BMI), the presence of hypertension (HTN), low optimism, and higher physical function were all associated with significantly greater mean decreases in global cognition (all p’s <.0.0001), but were not significantly different from the contrasting level (all p’s >0.05). Higher BMI, the presence of HTN, low optimism, and higher physical function were in turn protective of global cognitive decline postischemic stroke (all contrasting p values <.01). Baseline factors may play either a risk or a protective role in global cognitive function depending on the phase of ischemic stroke.     

An examination of age-related changes in the control of lexical and sublexical pathways in mapping spelling to sound

The current study investigated the extent to which young and older adults are able to direct attention to distinct processes in mapping spelling onto sound. Young and older adults completed either a speeded pronunciation task (reading aloud words) or regularization task (pronouncing words based on spelling-to-sound correspondences, e.g., pronouncing PINT such that it rhymes with HINT) in order to bias processing of lexical, whole-word information, or sublexical, spelling-to-sound mapping, respectively. Both younger and older adults produced reduced word-frequency effects and lexicality effects in the regularization task compared to the normal pronunciation task. Importantly, compared to younger adults, older adults produced exaggerated effects of task (i.e., pronunciation vs. regularization) on the observed frequency and lexicality effects. These results highlight both the flexibility of the lexical processing system and changes in the influence of the underlying lexical route due to additional 50 years of reading experience and/or changes in attentional control.     

Frequency and impact of trauma in older women: A military and nonmilitary sample

Understanding the impact of trauma on late-life functioning in older females is needed in order to provide best care. We explored the impact of trauma on late-life psychological and physical health and functioning among older women (n = 48) who served in the military, or participated in a military lifestyle. Eleven of these women were not veterans, but married to military personnel. Number of traumatic exposures and types of events experienced was associated with increased trauma symptom severity. Trauma symptom severity was associated with decreased physical functioning and increased pain. Increased numbing and avoidance was significantly associated with poorer physical functioning and increased pain. Older women in this study remained at risk of experiencing negative consequences of trauma in terms of increased quantity and severity of trauma symptoms and physical decline and pain. Clinical and research implications are discussed.     

Effects of problem presentation durations on arithmetic strategies: a study in young and older adults

Young and older adults were asked toaccomplish a computational estimation task (i.e. provide approximate sums to two-digit addition problems like 38 + 74) under a short versusa longer presentation duration condition. In a choice condition, participants selected the better strategy more often under a long than undera short presentation duration and after an easier than after a harder problem. In the no-choice condition, influence of presentation durationon strategy execution depended on the preceding problems, as participants showed sequence poorer strategy effects. That is, participantswere slower while executing the poorer than while executing the better strategy on current problems following better strategy problems (butequally fast after poorer strategy problems) only under short presentation duration condition. These findings have important theoreticalimplications, as current assumptions of computational models of strategies cannot explain how problem presentation durations influencestrategy selection and strategy execution.
