Gender Differences and Cognition Among Older Adults

The more replicated findings about gender difference in cognitive performance suggest female superiority on visuomotor speed and language ability and male superiority on mechanical and visuospatial tasks. Generally, group strengths found in the early school years become more established at adolescence and remain stable through adulthood. The current study tested whether the patterns established in the early years remained among 30 adult subjects. We also utilized a series of exploratory analyses to determine if observed gender differences were impacted by the covariance present between all cognitive tests. Results suggest that although the patterns established in the early years remain stable through time for males, the established patterns for females are altered with age. Our findings are compelling in supporting a male advantage on visuospatial tasks among older adults. These findings are discussed in terms of common variance between test instruments as a possible source of difference. Our finding that the gender effect tended to increase when common variance was controlled argues that this methodology may enhance the ability to detect domain specific effects.     

Effects of Stimulus Properties and Age on Random-Array Letter Cancellation Tasks

Random-array letter cancellation tasks are commonly used in the clinical assessment of visuospatial function. How stimulus properties and aging affect cancellation performance is not well understood. This study evaluated the effects of stimulus factors and age on 3 measures of cancellation performance. Thirty younger and 30 older adults each completed 12 cancellation forms that varied in paper size, stimulus density, and target-to-distractor (T/D) ratio. Interactions between stimulus factors were identified for a calculated composite measure of speed and accuracy (effectiveness), a standardized measure of the time required for completion of forms, and a standardized measure of the number of omission errors. The results showed complex interactions between stimulus factors that were different for each dependent variable. These interactions were generally similar for both age groups. The findings indicate that both stimulus properties and dependent variables must be carefully considered in the design and interpretation of cancellation paradigms.     

Trustworthiness and Moral Character

Why are people trustworthy? I argue for two theses. First, we cannot explain many socially important forms of trustworthiness solely in terms of the instrumentally rational seeking of one’s interests, in response to external sanctions or rewards. A richer psychology is required. So, second, possession of moral character is a plausible explanation of some socially important instances when people are trustworthy. I defend this conclusion against the influential account of trust as ‘encapsulated interest’, given by Russell Hardin, on which most trustworthiness is explained by the interest of continuing relationship.     

Health numeracy and cognitive decline in advanced age

ABSTRACT

The study aimed at investigating health numeracy in cognitively well performing healthy participants aged from 50 to 95 years as well as in participants with cognitive impairment, but no dementia (CIND). In cognitively well performing participants (n = 401), demographic variables and cognitive abilities (executive functions, reading comprehension, mental calculation, vocabulary) were associated with health numeracy. Older age, lower education, female gender as well as lower cognitive functions predicted low health numeracy. The effect of older age was partly mediated by executive functions and calculation abilities. Participants with CIND (n = 51) performed significantly lower than healthy controls in health numeracy. The findings suggest that cognitively well performing old individuals have difficulties in understanding health-related numerical information. The risk of misunderstanding health-related numerical information is increased in persons with CIND. As these population groups are frequently involved in health care decisions, particular attention has to be paid to providing numerical information in comprehensible form.     

The other side of the canvas: Lacan flips Foucault over Velázquez

This essay suggests that the minimal 1966 exchange between Jacques Lacan and Michel Foucault in Lacan’s seminar actually stood in for a much fuller debate about modernity, psychoanalysis and art than its brevity would indicate. Using their contrasting interpretations of Velázquez’s painting, Las Meninas, as its fulcrum, “The Other Side of the Canvas” discovers a Lacanian critique of Foucault’s history of modernity, circa The Order of Things. The effort here is to insert the interpretation of Velázquez into the context of both Lacan’s “Science and Truth” (originally the first session of the 1966 seminar) and Foucault’s recently published book. Our interpretation develops above all from Lacan’s contrast between the definition of a painting as a “window” and Foucault’s implicit understanding of it as a kind of “mirror”—a distinction in which Lacan discovers his seminal concept of “object a.” Pursuing the understanding of object a as the “surface” of the perspectival window allows us to understand why Lacan expands the discussion of Velázquez both into an understanding of twentieth-century paintings (Magritte, Balthus) and an implicit interpretation of the difference between philosophical and psychoanalytic approaches to science and history.     

Temperament Styles of Nigerian and U.S. Children

Abstract

Temperament styles of 400 Nigerian children are described in reference to possible gender and age differences and compared with those of 3200 U.S. children in light of Jung's theory of temperament as modified by Myers and Briggs, one that highlights four bipolar qualities: extroversion-introversion, practical-imaginative, thinking-feeling, and organized-flexible styles. Nigerian children generally prefer introverted to extroverted styles, practical to imaginative styles, feeling to thinking styles, and organized to flexible styles. In contrast to males, females are more likely to prefer feeling and organized styles. Age differences are seen only on organized-flexible styles, with a preference for flexible styles increasing with age. In contrast to U.S. children, Nigerian children tend to express higher preferences for introversion, practical, feeling, and organized styles.     

Body size and body esteem in women: The mediating role of possible self expectancy

We predicted that an expectancy of acquiring a feared fat self and an expectancy of acquiring a hoped-for thin self both mediate the impact of body size on women's body esteem. We also predicted that the mediating pathway through the feared fat self would be stronger than that through the hoped-for thin self. A community sample of 251 women reported their age, height, weight, and completed measures of body esteem and expectancy perceptions of acquiring the feared fat and hoped-for thin selves. Bayesian Structural Equation Modeling (SEM) demonstrated that expectancies about the feared fat self and about the hoped-for thin self mediated the relationship between body size and body esteem. Bayesian SEM also revealed that the pathway through the feared fat self was stronger than that through the hoped-for thin self. Implications for future research and the development of eating pathology are discussed.     

Drive for leanness and health-related behavior within a social/cultural perspective

We examined relationships between drive for leanness and perceived media pressure to change appearance, internalization of an ideal physique, exercise frequency, and dieting. Men and women (N = 353) completed the Drive for Leanness Scale, the Sociocultural Attitudes Toward Appearance Questionnaire-3, the Eating Attitudes Test-26, and a demographic inventory. Drive for leanness was significantly correlated with athletic internalization (.52), pressure to attain an ideal physique (.25), exercise frequency (.36), and dieting (.25). Structural equation modeling revealed a good fitting model (χ² = 2.85, p < .241; CFI = .99; NNFI = .98; RMSEA = .04; SRMR = .02) with internalization predicting drive for leanness, which in turn predicted dieting and exercise. Results reveal social/cultural theory helps enhance the understanding of the drive for leanness and its relationship with health-related behavior.     

Compartmentalization: A Window on the Defensive Self

Most people hold both positive and negative beliefs about themselves. The way individuals organize, or structure, these beliefs in their self‐concepts can facilitate realistic acceptance and confrontation of negative self‐beliefs (integration), or defensive avoidance and denial of negative self‐beliefs (compartmentalization). This article focuses on the distinction between individuals with a realistic, secure self and a defensive, fragile self. We present evidence that compartmentalization is associated with several indicators of a defensive, fragile self, such as contingent self‐esteem and unstable self‐evaluations. In addition, individuals with this structure are likely to engage in defensive processes that enhance or protect the self. This model of self‐organization can provide a window on the defensive self, allowing researchers to observe the process by which individuals think about and defensively avoid negative self‐beliefs.     

‘The Ostrich Problem’: Motivated Avoidance or Rejection of Information About Goal Progress

Monitoring one's current standing with respect to goals can promote effective self‐regulation. However, the present review suggests that there is an ostrich problem such that, in many instances, people have a tendency to “bury their head in the sand” and intentionally avoid or reject information that would help them to monitor their goal progress. For example, people with diabetes avoid monitoring their blood glucose, and few people monitor their household energy consumption, check their bank balances, keep track of what they are eating and so on. While situational constraints can explain some problems with progress monitoring, we use a self‐motives framework to posit that the decision to avoid monitoring often represents the product of an interaction between different motives. For example, the desire to accurately assess progress may conflict with the desire to protect or enhance the self. The present review collates evidence pertaining to the ostrich problem, identifies different motives that underlie the decision to monitor versus not monitor goal progress, illustrates how the ostrich problem might be integrated into models of self‐regulation, and provides suggestions for future research. In so doing, the review advances our understanding of the nature and determinants of intentionally deficient monitoring.
