Two studies were conducted to examine gymnasts' memory capabilities in relation to skill level (high and low) and age level (6–8 years and 14–16 years). The first experiment consisted of two trials performed 7 days apart. In the first trial, gymnasts were briefly exposed to a twelve‐element floor routine, and were then required to perform the routine in the same serial order. One week later they were again briefly presented the same sequence, but with the fifth and seventh elements missing. The task was to perform the sequence in order, including the missing elements. The second study involved three trials that were conducted on the same day. A ten‐element sequence was briefly presented on the first trial followed by an immediate test of that sequence. One hour later, participants were asked to perform the sequence again (delayed test). An hour following that, the sequence was again presented with two elements missing. The sequence had to be performed with the missing elements. The results indicate that serial position accuracy of a gymnastic floor routine improves with both age and experience, and that the older experienced gymnasts outperformed all the other gymnasts on all phases of the experiments. These results are interpreted within the Ericsson and Kintsch (1995) theory of Long‐term Working Memory. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

There is a large and growing literature on communal interpretive resources: the concepts, theories, narratives, and so on that a community draws on in interpreting its members and their world. (They’re also called “hermeneutical resources” in some places and “epistemic resources” in others.) Several recent contributions to this literature have concerned dominant and resistant interpretive resources and how they affect concrete lived interactions. In this article, I note that “using” interpretive resources—applying them to parts of the world in conversation with others—is “a rule‐governed activity”; and I propose that in oppressive systems, these rules are influenced by the rules of oppression. Section I clarifies some rules governing the use of resources. Section II draws on work by Gaile Pohlhaus, Jr. and others to suggest that according to the present rules of our oppressive system, it is permissible for dominantly situated speakers to dismiss interpretive resources developed in marginalized communities. Section III appeals to Charles Mills’s work on White ignorance to propose, further, that our system’s rules make it impermissible and deserving of punishment to use resistant resources. The conclusion enumerates several further points about such rules governing the use of interpretive resources, their social effects, and some philosophical literatures.  相似文献

Using existing longitudinal data from 570 infants in the Maternal Lifestyle Study, we explored the predictive value of maternal and infant affect and maternal vocalizations during 2 minutes of face‐to‐face interactions at 4 months on IQ scores at 4.5 and 7 years. After controlling for demographic factors, maternal depression, and prenatal drug exposure, maternal positive affect and maternal positive vocalizations emerged as predictors of both verbal and performance IQ at 4.5 and 7 years. Although infant positive affect during the interaction with the mother was not predictive of these outcome measures, infant positive affect towards an examiner predicted verbal but not performance IQ at 4.5 years. These results suggest that maternal positive affect may index emotional engagement in interaction that facilitates both verbal and nonverbal cognitive development, while infant social positive affect is specifically related to the acquisition of verbal reasoning abilities. These findings are significant because they are based on a discrete snapshot of observable behavior in infancy (just 2 minutes of interaction), because they extend the range of maternal behaviors and characteristics known to support positive developmental outcomes, and because they are derived from high‐risk infants where prevention efforts may be beneficial. Potential mechanisms for these associations are discussed, as are the clinical implications for identifying dyads most in need of targeted interventions.  相似文献

The authors tested whether 2 doses of remote limb ischemic conditioning (RLIC), induced via blood pressure cuff inflation, enhanced motor and cognitive learning to an equal extent, and explored a panel of blood biomarkers of RLIC. Thirty-two young adults were randomized to 3 groups and underwent a 7-day protocol of RLIC/sham followed by motor and cognitive training, with follow-up. Both RLIC groups had greater motor learning and a trend toward greater cognitive learning compared with the sham group. RLIC at the lower inflation pressure was as effective as RLIC with the higher inflation pressure. No significant candidate blood biomarkers were found. RLIC could be a well-tolerated method to enhance learning and improve rehabilitation outcomes in people with neurological conditions.  相似文献

Americans’ opinions about crime and justice are more often shaped by media coverage than by scientific evidence. A prime example of this phenomenon is Arts and Entertainment (A&E) Network’s Beyond Scared Straight program—a show that has achieved strong ratings despite the large body of empirical evidence demonstrating the ineffectiveness of inmate–juvenile confrontation tactics. To understand the complexity of American citizens’ opinions toward this program, we conducted a qualitative analysis of the online responses to the television series Beyond Scared Straight. The themes that emerged center around beliefs about the effectiveness of Scared Straight, the level of brutality displayed, its inspirational and emotional content, and its authenticity. We discuss these results in terms of the need for scholars to more effectively communicate social science information concerning what does—and does not—“work” to the public and to correctional policymakers.  相似文献

Abstract

Beginning with the situated character of the question concerning the human, this paper argues that the problem of the human is itself inextricably bound to the problem of situation or place. Consequently, any genuine philosophical anthropology must take the form of a philosophical topology. This line of argument is developed through the work Abraham Heschel, Martin Heidegger, Martin Buber, and also Helmut Plessner.  相似文献

An original model of shame- and guilt-related emotions is proposed and the model's theoretical background discussed. Shame is conceptualized as an affect (i.e., basic emotion), elicited by personal devaluation and evolved by social selection. Guilt is conceptualized as a cognitively assessed condition. In response to awareness of one's own condition of guilt, one may feel a number of affects or no affect. The phrase feeling guilty is a non-specific reference to feeling as one typically feels when in the condition of guilt [Ortony, A. (1987). Is guilt an emotion? Cognition and emotion, 1, 283-298]. Thus, shame as a construct represents a single affect, while feelings of guilt represent multiple affective-cognitive hybrids, which may be associated with the condition of guilt. In terms of levels of categorization [Rosch, E. (1978). Principles of categorization. In E. Rosch & B. B. Lloyd (Eds.), Cognition and categorization (pp. 27-48). Hillsdale, NJ: Erlbaum], shame, as an affect, is a basic level category with subordinates such as embarrassment and humiliation; in contrast, the multiple feelings of guilt constitute multiple subordinate affective-cognitive hybrids—subordinate to a number of basic level affects. This model integrates a great deal of existing data, suggests a large number of hypotheses, and implies the need for a profile approach to the assessment of guilt. By conceptualizing shame as an affect, and making the distinction between guilt as a state and the multiple affective-cognitive hybrids of guilt, much of the confusion and imprecision in past theory and research may be clarified.  相似文献

Three patterns of mutual intimate partner violence (IPV) are proposed, based on frequency and severity: Male primary perpetrator (MPP), female primary perpetrator (FPP), and symmetrical (SYM). Patterns and effects of ethnicity were examined with 445 African American, Euro-American, and Mexican American low-income women experiencing mutual IPV. More relationships were classified as MPP (54%) than SYM (35%) or FPP (11%). Comparing women's and men's perpetration of several types of IPV (e.g., threats, severe physical) indicated MPP-pattern women experienced all IPV types more often and were more likely to sustain injury than their male partners. Fewer gender differences were found in the FPP pattern. Racial/ethnic groups were more similar than different; previously reported differences may be explained by variation in socioeconomic status. The larger part of the study was funded by grant R49/CCR610508 from the National Center for Injury Prevention and Control of the Centers for Disease Control and Prevention, awarded to the third author. This article was also made possible by grant 2001-WT-BX-0504 from the National Institute of Justice awarded to the first and third authors. These agencies are not responsible for the results. Portions of this paper were presented by the first and third authors at the International Family Violence Conference in Portsmouth, NH, July, 2003.  相似文献

The Spearman-Kärber method can be used to estimate the threshold value or difference limen in two-alternative forced-choice tasks. This method yields a simple estimator for the difference limen and its standard error, so that both can be calculated with a pocket calculator. In contrast to previous estimators, the present approach does not require any assumptions about the shape of the true underlying psychometric function. The performance of this new nonparametric estimator is compared with the standard technique of probit analysis. The Spearman-Kärber method appears to be a valuable addition to the toolbox of psychophysical methods, because it is most accurate for estimating the mean (i.e., absolute and difference thresholds) and dispersion of the psychometric function, although it is not optimal for estimating percentile-based parameters of this function.  相似文献
