The relationship between cognitive function and life space: the potential role of personal control beliefs

We examined the relationship of cognitive and functional measures with life space (a measure of spatial mobility examining extent of movement within a person's environment) in older adults, and investigated the potential moderating role of personal control beliefs. Internal control beliefs reflect feelings of competence and personal agency, while attributions of external control imply a more dependent or passive point of view. Participants were 2,737 adults from the ACTIVE study, with a mean age of 74 years. Females comprised 76% of the sample, with good minority representation (27% African American). In multiple regression models controlling for demographic factors, cognitive domains of memory, reasoning, and processing speed were significantly associated with life space (p < .001 for each), and reasoning ability appeared most predictive (B = .117). Measures of everyday function also showed significant associations with life space, independent from the traditional cognitive measures. Interactions between cognitive function and control beliefs were tested, and external control beliefs moderated the relationship between memory and life space, with the combination of high objective memory and low external control beliefs yielding the highest life space (t = -2.07; p = .039). In conclusion, older adults with better cognitive function have a larger overall life space. Performance-based measures of everyday function may also be useful in assessing the functional outcome of life space. Additionally, subjective external control beliefs may moderate the relationship between objective cognitive function and life space. Future studies examining the relationships between these factors longitudinally appear worthwhile to further elucidate the interrelationships of cognitive function, control beliefs, and life space.     

How Hume’s Philosophy Informed Radical Behaviorism

The present paper analyzes consistencies between the philosophical systems of David Hume and B. F. Skinner, focusing on their conceptualization of causality and attitudes about scientific behavior. The ideas that Hume initially advanced were further developed in Skinner’s writings and shaped the behavior-analytic approach to scientific behavior. Tracing Skinner’s logical antecedents allows for additional historical and philosophical clarity when examining the development of radical behaviorism.     

From developmental metaphor to developmental model: the shrinking role of language in the talking cure

Psychoanalysts have invoked infant development diversely to understand nonverbal and unspoken aspects of lived experience. Two uses of developmental notions and their implications for understanding language and the therapeutic action of psychoanalysis are juxtaposed here: Hans Loewald's conception of developmental metaphors to illuminate ineffable aspects of the clinical situation and Daniel Stern's currently popular developmental model, which draws on findings from quantitative research to explain therapeutic action in the nonverbal realm. Loewald's metaphorical use of early development identifies and thus potentiates a central role for language in psychoanalytic treatment. By contrast, Stern and his colleagues exaggerate the abstract, orderly, and disembodied qualities of language, and consequently underestimate the degree to which lived interpersonal experience can be meaningfully verbalized, as demonstrated here with illustrations from published clinical material. As contemporary psychoanalysis moves toward embracing developmental models such as Stern's, it is concluded, psychoanalysts accept a shrinking role for language in the talking cure.     

Merciful Justice

I offer a solution to an old puzzle about how God can be both just and merciful at the same time—a feat which seems required of God, but at the same time seems impossible since showing mercy involves being more lenient than justice demands. Inspired by two of Jesus’ parables and work by Feinberg, Johnson and Smart, I suggest that following a “principle of merciful justice”—that persons ought to receive what they deserve or better—delivers mercy and justice simultaneously, certainly in cases of distributions of goods, and even in cases of distribution of harms as well, if we can accept some qualifications.     

Uncovering Visitor Conceptions of Fossils and the Fossil Record

ABSTRACT

One of the common features of any natural history museum is its fossil collection. A visitor's prior knowledge of and experience with these prehistoric objects is expected to greatly influence how visitors make sense of these iconic displays. For this study, over 150 visitors to two natural history museums in Southern California were interviewed to find out what they knew about fossils and the fossil record. Findings showed that visitors referenced a wide range or breadth of salient characteristics when defining fossils and that almost two-thirds mentioned some sort of process for the formation of fossils. When asked to interpret a diagram of geological strata and fossil placement within the strata, most visitors recognized that older fossils were found in lower layers (suggesting an understanding of the principle of superposition), although this was age-dependent. Also, many visitors explained fossil distribution in terms of some sort of change process—either related to the organism or the environment. In addition, several potential misconceptions related to fossils and superposition also emerged from the analysis. Implications for supporting visitor understanding are discussed.     

Can Messages Make a Difference? The Association Between E‐Mail Messages and Health Outcomes in Diabetes Patients

This investigation examined the impact of social support messages on patient health outcomes. Forty‐one American Indian, Alaska Native, and Native Hawaiian patients received a total of 618 e‐mail messages from their healthcare provider (HCP). The e‐mail messages were divided into 3,565 message units and coded for instances of emotional social support. Patient glycosulated hemoglobin scores (HbA1c) showed significantly improved glycemic control and emotional social support messages were associated with significant decreases in HbA1c values. Patient involvement with the system, measured by system login frequency and the frequency of uploaded blood glucose scores to the HCP, did not predict change in HbA1c.
