Pictorial rehearsal effects in younger and older adults

Abstract

In three studies, we examined pictorial rehearsal effects in younger and older adults. Concrete and abstract line drawings that varied in the amount of pictorial detail were presented for study under different presentation conditions. In the pictorial rehearsal condition, each picture was followed by a blank rehearsal interval where the picture was no longer presented. In all three experiments, the poststimulus interval enhanced picture recognition for both age groups, relative to a control condition where no rehearsal interval occurred. These findings suggest that older adults, like younger adults, form and maintain visual images across a blank rehearsal interval. Implications of these findings for current views on imaginal processes in older adults are discussed.     

Body size dissatisfaction and avoidance behavior: How gender,age, ethnicity,and relative clothing size predict what some won’t try

Sixty-eight percent of U.S. adults are overweight/obese, and this epidemic has physical, psychosocial, and behavioral consequences. An internet sample of adults (N = 2997) perceiving themselves as larger than ideal in clothing size reported their body mass index (BMI), relative clothing size (RS; discrepancy between current and ideal size), and avoidance behaviors. Exploratory factor analysis of 10 avoidance items produced social avoidance and body display avoidance factors. A relative importance analysis revealed RS as a better predictor than BMI for avoidance. A hierarchical multivariate analysis of covariance found RS to predict both avoidance constructs. The relationship between RS and both avoidance constructs was stronger for women than men, and for younger as compared to older participants. Caucasians reported more body display avoidance than African Americans. This suggests that personal dissatisfaction with body size may deter involvement in varied life events and that women are especially avoidant of activities that entail displaying their bodies.     

Alteration of affective Theory of Mind in amnestic mild cognitive impairment

The concept of amnestic mild cognitive impairment (aMCI) concerns a population of older individuals at high risk of developing probable Alzheimer's disease (AD). Impairments of the cognitive component of Theory of Mind (ToM), that is the inference about other people's beliefs, have been well documented in AD; on the contrary, controversial findings have been reported on the affective component of ToM (inference about other's feelings), a process mainly based on medial portions of the prefrontal cortex. The current study aimed at evaluating the affective component of ToM in aMCI subjects. Twenty aMCI subjects and 20 age‐matched healthy controls (HC) underwent a standard neuropsychological assessment and the assessment of affective ToM with the full 36‐item version of reading the mind in the eyes (RME). Although aMCI subjects had formal impaired performances only in memory tasks, HC outperformed aMCI subjects in several cognitive tasks, including also the RME (mean RME scores 21.7 ± 3.0 vs. 17.0 ± 3.8%; 60.3% of correct answers vs. 47.2%). The lower RME performance of aMCI patients provides the first empirical evidence that aMCI may be associated with difficulties in tasks of affective ToM, in accordance with recent findings of early difficulties of aMCI patients in other processes that are mainly dependent on the medial prefrontal cortex, such as reversal learning and decision making under ambiguity. Findings of the current study need further empirical confirmation in larger samples of aMCI patients and also the investigation of other MCI subtypes is needed.     

Spiritual Development Across the Adult Life Course: Findings from a Longitudinal Study

Longitudinal data spanning early (30s) and older (late 60s/mid-70s) adulthood were used to study spiritual development across the adult life course in a sample of men and women belonging to a younger (born 1928/29) and an older (born 1920/21) age cohort. All participants, irrespective of gender and cohort, increased significantly in spirituality between late middle (mid-50s/early 60s) and older adulthood. Members of the younger cohort increased in spirituality throughout the adult life cycle. In the second half of adulthood, women increased more rapidly in spirituality than men. Spiritual involvement in older age was predicted by religious involvement and personality characteristics in early adulthood and subsequent experiences of negative life events.     

Consumer misbehaviour: an exploratory study of shopliftin

Although customer theft is traditionally researched from a criminological or psychological perspective, this paper investigates shoplifting as consumer behaviour, demonstrating that well‐defined models of normal consumer behaviour can be applied to aberrant behaviour such as shop theft. Empirical research is used to show how adults and teenagers form belief systems that amount to rational intentions in the decision to shoplift. The theory of planned behaviour (Ajzen, 1991) was used as the basis for two self‐report surveys which investigated the interaction between consumers' attitudes and beliefs about shoplifting and their perceptions of retail security. The first survey utilised a sample of shoppers from the South East Midlands; the second a sample of school students from the same area (861 respondents in total, 109 respondents admitting to shoplifting in the previous year). Both studies indicate that the decision to shoplift is influenced by pro‐shoplifting attitudes, social factors, opportunities for shoplifting and perceptions of low risks of apprehension. This implies that the deterrent messages we use must be reassessed. Copyright © 2002 Henry Stewart Publications.     

Solo status, stereotype threat, and performance expectancies: Their effects on women’s performance

Women working in male-dominated environments may find themselves to be the only woman present, and that negative stereotypes about women persist in the environment. This experiment tested women’s performance in solo status (SS: being the only woman present) and under stereotype threat (ST: when women are stereotyped as poor performers). White male and female participants (157) learned information, then tested on it in an opposite-gender (SS) or same-gender group (nonsolo). In addition, the information was described as being traditional math material (ST) or a type of math information impervious to gender stereotypes (no threat). Women performed more poorly in SS than nonsolos, and under ST than no threat. Experiencing both factors was more detrimental to women’s performance than experiencing one or the other. Men’s performance was the same across all conditions. Performance expectancies partially mediated the effect of SS, but not ST, on performance.     

Manifestability and Semantic Realism

Abstract: This paper provides a critical discussion of Alexander Miller's recent attack on antirealist arguments against semantic realism that are based on manifestability requirements. Miller attempts to defend semantic realism against Wright-Hale arguments from manifestability. He does so in reliance on a McDowell type assertion-truth platitude. This paper argues in both general terms and in relation to the details of Miller's argument, that attempts to defend semantic realism while accepting a Dummettian-Wittgensteinian framework on theories of meaning, are misconceived and likely to fail, as I believe is true in Miller's case. Semantic realism is best defended within a context of metaphysical realism, and naturalistic-causal theories of meaning and explanation.
