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. 相似文献

ABSTRACTThe 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. 相似文献

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. 相似文献

AbstractTemperament 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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

In a spoken utterance, a talker expresses linguistic constituents in serial order. A listener resolves these linguistic properties in the rapidly fading auditory sample. Classic measures agree that auditory integration occurs at a fine temporal grain. In contrast, recent studies have proposed that sensory integration of speech occurs at a coarser grain, approximate to the syllable, on the basis of indirect and relatively insensitive perceptual measures. Evidence from cognitive neuroscience and behavioral primatology has also been adduced to support the claim of sensory integration at the pace of syllables. In the present investigation, we used direct performance measures of integration, applying an acoustic technique to isolate the contribution of short-term acoustic properties to the assay of modulation sensitivity. In corroborating the classic finding of a fine temporal grain of integration, these functional measures can inform theory and speculation in accounts of speech perception. 相似文献

Efficient selection of actions is dependent on higher-level constraints (mental sets) on lower-level selection. This paper explores the hypothesis that ageing leads to specific impairments associated with higher-level selection between mental sets. Indirect evidence for such a deficit comes from occasional findings of age differences in situations with high executive-control demands (e.g., Mayr & Kliegl, 1993) that are not easily explained in terms of other factors, such as general slowing or working memory parameters. More direct evidence comes from recent results with the so-called task-switching paradigm. Specifically, age-sensitive set-selection processes are indicated by age differences in “global selection costs” (i.e., the response-time difference between task-switching blocks and single-task blocks) which seem to be particularly large when demands in terms of “keeping competing mental sets apart” are high. Finally, data from a new variant of the task-switching paradigm (the “fade-out paradigm”) are reported which show that age differences in global costs persist substantially beyond a phase in which set-selection is actually necessary. Generally, evidence is consistent with the view that in older age, a costly set-selection mode of processing dominates over the more efficient within-set-selection mode of processing, possibly because of a problem with maintaining distinct representations of what ought to be done in the face of competing representations of what could be done in principle. 相似文献
