What frame of reference do we use to remember observed movements? One possibility is that visual working memory (VWM) retains movement information using a retinotopic frame of reference: A coordinate system with respect to the retina that retains view-dependent information. Alternatively, VWM might retain movement information using an allocentric frame of reference: A coordinate system with respect to the scene that retains view-invariant information. To address this question, I examined whether VWM retains view-dependent or view-invariant movement information. Results show that (1) observers have considerable difficulty remembering from which viewpoints they observed movements after a few seconds' delay, and (2) the same number of movements can be retained in VWM whether the movements are encoded and tested from the same viewpoint or from different viewpoints. Thus, movement representations contain little to no view-dependent information, which suggests that VWM uses an allocentric reference frame to retain movement information. 相似文献

Case-based instruction has been regarded by many as a viable alternative to traditional lecture-based education and training. However, little is known about how case-based training techniques impact training effectiveness. This study examined the effects of two such techniques: (a) presentation of alternative outcome scenarios to a case, and (b) conducting a structured outcome evaluation. Consistent with the hypotheses, results indicate that presentation of alternative outcome scenarios reduced knowledge acquisition, reduced sensemaking and ethical decision-making strategy use, and reduced decision ethicality. Conducting a structured outcome evaluation had no impact on these outcomes. Results indicate that those who use case-based instruction should take care to use clear, less complex cases with only a singular outcome if they are seeking these types of outcomes. 相似文献

This paper reports on the relationships between quality of life, spiritual well-being, and psychological adjustment styles for people living with leukaemia. Participants were 40 adults (26 women and 14 men) aged between 22 and 80 years living with acute or chronic leukaemia in Western Australia. Participants completed three scales measuring spiritual well-being (FACIT-Sp-12-C Version 4; Cella, 1997), psychological adjustment styles (MAC; Watson, Greer, & Bliss, 1989), and quality of life (FACIT-G; Cella, 1997). No differences were found between the men and women participants, with the exception of the anxious preoccupation adjustment style. Significant positive correlations were found between spiritual well-being and quality of life (r?=?0.72, p?=?<0.01), and between fighting spirit and both spiritual well-being (r?=?0.55, p?<?0.01) and quality of life (r?=?0.67, p?<?0.01). Spiritual well-being and quality of life were both significantly negatively correlated with hopelessness/helplessness, fatalism, and anxious preoccupation, suggesting that people who are able to find meaning in their illness are more likely to utilize functional psychological adjustment styles. A stepwise multiple regression revealed that spiritual well-being was most strongly associated with quality of life for people living with leukaemia, followed by a fighting spirit; together, these accounted for 61% of the variance in quality of life scores. Thus, having a reason for living, making life more productive, finding comfort in faith or spiritual beliefs, being determined to control the environment, and feeling a sense of meaning, peace, harmony, purpose, and comfortable in oneself are factors that contribute to a better quality of life among patients with leukaemia. Strengths, limitations, and implications of the findings are discussed. 相似文献

ABSTRACT The impact of age-related changes in visual-perceptual processing on naming ability has not been reported. The present study investigated the effects of 6 levels of spatial frequency and 6 levels of contrast on accuracy and latency to name objects in 14 young and 13 older neurologically normal adults with intact lexical-semantic functioning. Spatial frequency and contrast manipulations were made independently. Consistent with the hypotheses, variations in these two visual parameters impact naming ability in young and older subjects differently. The results from the spatial frequency-manipulations revealed that, in general, young vs. older subjects are faster and more accurate to name. However, this age-related difference is dependent on the spatial frequency on the image; differences were only seen for images presented at low (e.g., 0.25–1 c/deg) or high (e.g., 8–16 c/deg) spatial frequencies. Contrary to predictions, the results from the contrast manipulations revealed that overall older vs. young adults are more accurate to name. Again, however, differences were only seen for images presented at the lower levels of contrast (i.e., 1.25%). Both age groups had shorter latencies on the second exposure of the contrast-manipulated images, but this possible advantage of exposure was not seen for spatial frequency. Category analyses conducted on the data from this study indicate that older vs. young adults exhibit a stronger nonliving-object advantage for naming spatial frequency-manipulated images. Moreover, the findings suggest that bottom-up visual-perceptual variables integrate with top-down category information in different ways. Potential implications on the aging and naming (and recognition) literature are discussed. 相似文献

The present study examined the role of parenting styles and basic psychological needs in the adoption of goals and aspirations of learners, as well as for their psychological wellbeing (positive versus negative affect) in a South African sample of learners. A cross-sectional design was used to conduct this study with a sample of 853 learners at public schools in the Western Cape of South Africa (females?=?57%, mean age 16.96 years, SD?=?1.12). Data were collected using the Parenting Style and Dimensions Questionnaire (PSDQ), Psychological Needs Scale, Aspiration Index and the Positive And Negative Affect Schedule (PANAS). The results suggest that authoritative and authoritarian parenting styles influence the adoption of life goals and psychological wellbeing of adolescents with fathers' negative parenting possibly reducing adolescent wellbeing. Extrinsic life goals was a significant predictor of positive affect, while need frustration was a significant predictor of negative affect. These findings suggest parenting styles and basic psychological needs influence life aspirations and psychological wellbeing of learners in a developing country context. 相似文献

The present study explored African American (n = 16) and European American (n = 19) college women's ideal body size perceptions for their own and the other ethnic group along with reasons behind their selections. Respondents completed an ethnically-neutral figure rating scale and then participated in ethnically-homogenous focus groups. European Americans mostly preferred a curvy-thin or athletic ideal body while most African American students resisted notions of a singular ideal body. European Americans suggested that African Americans’ larger ideal body sizes were based on greater body acceptance and the preferences of African American men. African Americans used extreme terms when discussing their perceptions of European Americans’ thin idealization, celebrity role models, and weight management behaviors. African Americans’ perceptions of European Americans’ body dissatisfaction were also attributed to the frequent fat talk they engaged in. Implications for promoting the psychosocial well-being of ethnically-diverse emerging adult females attending college are discussed. 相似文献

In this study, associations were examined between cortisol levels of wives and husbands in 47 heterosexual married couples. Both partners' salivary cortisol levels were measured at the same moments seven times a day on 2 typical weekdays. After accounting for the effects of the diurnal rhythm of cortisol and relevant control variables, dyadic hierarchical linear modeling indicated significant positive linkages between partners' cortisol levels, consistent with the hypothesized within‐couple physiological synchrony. Variables reflecting more (spousal presence) or less connectedness (loneliness, being alone) were also collected at the time of each cortisol sample. Results indicated that husbands' cortisol levels were higher at moments they reported feeling lonelier and lower at moments they were in the presence of their spouse. Wives' cortisol levels were higher at moments they were alone. In addition, wife–husband cortisol synchrony was stronger for husbands who spent relatively more time with their spouse across the study period—even after accounting for time spent with others in general. These findings suggest that marital partners evidence positive within‐couple cortisol associations, and that connectedness (particularly physical closeness) may underpin spouses' physiological synchrony. 相似文献

Paul Guyer's paper “Naturalistic and Transcendental Moments in Kant's Moral Philosophy” raises a set of issues about how Kantian ethics should be understood in relation to present day “philosophical naturalism” that are very much in need of discussion. The paper itself is challenging, even in some respects iconoclastic, and provides a highly welcome provocation to raise in new ways some basic questions about what Kantian ethics is and what it ought to be. Guyer offers us an admirably informed and complex argument, both historical and philosophical, that tangles with some of the most difficult problems in Kant's moral philosophy. It begins with some ambitious and controversial claims about Kant's moral philosophy prior to the Groundwork of 1785. It then offers an interpretation, and also a fundamental criticism, of the Groundwork's attempt to establish the moral law based on the idea of freedom of the will. And finally, it raises – and expresses some opinions on – the large and vexed questions of the relationship between transcendental philosophy and philosophical naturalism, and whether Kantian ethics can be made consistent with a naturalistic philosophical outlook. In these comments I will have something to say on each of these three topics, without pretending (any more than Guyer does) to have exhausted what might be said about them. 相似文献

Is it possible to enhance the subjective wellbeing of individuals and societies? If so, what are the mental health interventions and economic mechanisms by which subjective wellbeing could be enhanced? We address these questions in our review of the literature on subjective wellbeing. Research now shows that although subjective wellbeing is heritable and stable, it can change substantially over time. Long‐term changes can be affected by positive or negative life events; subjective wellbeing interventions have also proved to be effective for boosting wellbeing for as long as six months. At the societal level, economic factors matter for the subjective wellbeing of citizens. Economic wealth is shown to be a predictor of societal wellbeing across countries and over time. Also, high unemployment severely lowers the wellbeing of individuals and has spillover effects on other societal members, such as the employed. Given the weight of evidence, we are optimistic that subjective wellbeing can be enhanced. For practitioners, policy makers, and economists interested in the wellbeing of individuals, we propose that these findings have implications for mental health practice and economic policies. Future research and methodological issues are discussed. 相似文献

Little longitudinal research has been conducted on changes in children's emotional self-regulation strategy (SRS) use after infancy, particularly for children at risk. In this study, the authors examined changes in boys’ emotional SRS from toddlerhood through preschool. Repeated observational assessments using delay of gratification tasks at ages 2, 3, and 4 years were examined with both variable- and person-oriented analyses in a low-income sample of boys (N = 117) at risk for early problem behavior. Results were consistent with theory on emotional SRS development in young children. Children initially used more emotion-focused SRS (e.g., comfort seeking) and transitioned to greater use of planful SRS (e.g., distraction) by 4 years of age. Person-oriented analysis using trajectory analysis found similar patterns from 2 to 4 years, with small groups of boys showing delayed movement away from emotion-focused strategies or delay in the onset of regular use of distraction. The results provide a foundation for future researchers to examine the development of SRS in low-income young children. 相似文献
