Preferences and life evaluations of older adults with and without dementia: reliability, stability, and proxy knowledge

This study assessed the reliability and stability of care preferences and life evaluations among older adults with and without dementia. The study also examined spouse proxy predictions of partner responses. Test-retest reliability over 1 week, stability over 1 year, and proxy knowledge were all moderate to good, but lower for people with dementia. In all 3 areas, however, there was broad interindividual variability. People with dementia may become less reliable and stable in their self-reports, and some spouse proxies may have flawed knowledge about their partner, but dementia status alone is not sufficient to presume poor reliability or knowledge.     

Shared intentionality

We argue for the importance of processes of shared intentionality in children's early cognitive development. We look briefly at four important social-cognitive skills and how they are transformed by shared intentionality. In each case, we look first at a kind of individualistic version of the skill -- as exemplified most clearly in the behavior of chimpanzees -- and then at a version based on shared intentionality -- as exemplified most clearly in the behavior of human 1- and 2-year-olds. We thus see the following transformations: gaze following into joint attention, social manipulation into cooperative communication, group activity into collaboration, and social learning into instructed learning. We conclude by highlighting the role that shared intentionality may play in integrating more biologically based and more culturally based theories of human development.     

The Critical Need to Recognize That Families Matter for Adult Health: A Systematic Review of the Literature

A systemic approach to researching families and health should capture the complex network within which family members are embedded, including multiple family relationships and larger systems of health care. However, much of the families and health research focused on adult family members has focused solely on intimate partnerships, usually the marital relationship. This neglects the remainder of the powerfully influencing family relationships adults retain, and may increasingly focus on as they age. We conducted a systematic review of the families and adult health literature, retaining 72 articles which were subsequently thematically coded to highlight main foci of this area of research. Results highlight six themes, which include family relationship quality, family composition, behavioral factors in health and health care, psychophysiological mediators, caregiving, and aging health. Findings support an underrepresentation of family members, other than the intimate partner, in research on adult health.     

An item‐level investigation of conceptual and empirical distinctiveness of proactivity constructs

Beyond the prior investigations that took scale‐level approaches to determining discriminant validity in proactivity constructs, the current study contributes a much‐needed interrogation of the items used to measure the behaviors in this domain. The substantive validity (SV) assessments (Study 1) showed that many of the items were judged to be inconsistent with the definition of the construct they assess or, alternatively, more consistent with the definition of a different construct in the domain. Further, exploratory factor analysis revealed the difficulty in empirically separating the four behaviors, while BiM results also advocated against the unique variance of them after accounting for a general factor (Study 2). Altogether, our results show that the items are partly to blame for the empirical redundancy issue.     

The reliability of a model influences 14-month-olds’ imitation

Human infants have an enormous amount to learn from others to become full-fledged members of their culture. Thus, it is important that they learn from reliable, rather than unreliable, models. In two experiments, we investigated whether 14-month-olds (a) imitate instrumental actions and (b) adopt the individual preferences of a model differently depending on the model’s previous reliability. Infants were shown a series of videos in which a model acted on familiar objects either competently or incompetently. They then watched as the same model demonstrated a novel action on an object (imitation task) and preferentially chose one of two novel objects (preference task). Infants’ imitation of the novel action was influenced by the model’s previous reliability; they copied the action more often when the model had been reliable. However, their preference for one of the novel objects was not influenced by the model’s previous reliability. We conclude that already by 14 months of age, infants discriminate between reliable and unreliable models when learning novel actions.

Selective copying of the majority suggests children are broadly “optimal‐” rather than “over‐” imitators

Human children, in contrast to other species, are frequently cast as prolific “over‐imitators”. However, previous studies of “over‐imitation” have overlooked many important real‐world social dynamics, and may thus provide an inaccurate account of this seemingly puzzling and potentially maladaptive phenomenon. Here we investigate this topic using a cultural evolutionary approach, focusing particularly on the key adaptive learning strategy of majority‐biased copying. Most “over‐imitation” research has been conducted using consistent demonstrations to the observer, but we systematically varied the frequency of demonstrators that 4‐ to 6‐year‐old children observed performing a causally irrelevant action. Children who “over‐imitate” inflexibly should copy the majority regardless of whether the majority solution omits or includes a causally irrelevant action. However, we found that children calibrated their tendency to acquire the majority behavior, such that copying did not extend to majorities that performed irrelevant actions. These results are consistent with a highly functional, adaptive integration of social and causal information, rather than explanations implying unselective copying or causal misunderstanding. This suggests that our species might be better characterized as broadly “optimal‐” rather than “over‐” imitators.
