One-year cognitive outcomes from a multiple real-world skill learning intervention with older adults.

OBJECTIVES: Novel skill learning has been shown to have cognitive benefits in the short-term (up to a few months). Two studies expanded on prior research by investigating whether learning multiple novel real-world skills simultaneously (e.g. Spanish, drawing, music composition), for a minimum of six hours a week, would yield 1-year cognitive gains. METHOD: Following a 3-month multi-skill learning intervention, Study 1 (N = 6, Mage = 66 years, SDage = 6.41) and Study 2 (N = 27, Mage = 69 years, SDage = 7.12) participants completed follow-up cognitive assessments 3 months, 6 months, and one year after the intervention period. Cognitive assessments tested executive function (working memory and cognitive control) and verbal episodic memory. RESULTS: Linear mixed-effects models revealed improvements in multiple cognitive outcomes from before the intervention to the follow-up timepoints. Specifically, executive function increased from pre-test to the 1-year follow-up for both studies (an effect driven mostly by cognitive control scores). DISCUSSION: Our findings provide evidence that simultaneously learning real-world skills can lead to long-term improvements in cognition during older adulthood. Future work with diverse samples could investigate individual differences in gains. Overall, our findings promote the benefits of lifelong learning, namely, to improve cognitive abilities in older adulthood.

Social Mobility and Sense of Purpose From Midlife to Old Age: Examining the Role of Major Life Events.

Purpose in life (PIL) has been linked with numerous health benefits and adaptive aging, yet it diminishes with age, possibly due to loss of social or familial roles through life transitions. Drawing from the longitudinal surveys of the Midlife in the US study (n = 3418), we use time-varying coefficient models to investigate how the trajectory of PIL differs across cumulatively (dis)advantaged, upwardly mobile, and downwardly mobile groups and the role of major life events in shaping these trajectories. We found the upwardly mobile group exhibits higher PIL than the cumulatively disadvantaged and downwardly mobile groups. The consistently disadvantaged group experiences more adverse events at non-normative times. Socioeconomic status disparities in PIL during old age decrease after controlling for life events. We discuss how and why well-being changes and the role of structural and social factors in facilitating or impeding the development or maintenance of PIL over the life course.

Categorization in infancy based on novelty and co-occurrence.

categories (i.e., groups of objects that do not share perceptual features, such as food) abound in everyday situations. The present looking time study investigated whether infants are able to distinguish between two abstract categories (food and toys), and how this ability may extend beyond perceived information by manipulating object familiarity in several ways. Test trials displayed 1) the exact familiarized objects paired as they were during familiarization, 2) a cross-pairing of these same familiar objects, 3) novel objects in the same category as the familiarized items, or 4) novel objects in a different category. Compared to the most familiar test trial (i.e., Familiar Category, Familiar Objects, Familiar Pairings), infants looked longer to all other test trials. Although there was a linear increase in looking time with increased novelty of the test trials (i.e., Novel Category as the most novel test trial), the looking times did not differ significantly between the Novel Category and Familiar Category, Unfamiliar Objects trials. This study contributes to our understanding of how infants form object categories based on object familiarity, object co-occurrence, and information abstraction.
