Although disproportionate inversion effects have often been considered manifestations of the special processes recruited by upright faces, several papers using sequential matching tasks have reported that body postures also produce sizeable inversion effects. However, comparison of inversion effects observed with transient body postures and effects elicited by judgements of facial structure is complicated by qualitative differences between the stimuli and the tasks. Here we report a series of experiments that use attractiveness judgements to provide a better comparison of the effect of inversion as well as contrast negation on face and body perception. Significant effects of inversion and negation were observed for both face and body stimuli. While the magnitude of the inversion effects was broadly comparable, the negation effect was considerably larger for faces. These effects converge with evidence from cognitive neuroscience to suggest that both faces and bodies recruit similar orientation-specific processes distinct from processes used for generic objects. 相似文献

Using the Chinese Ring Puzzle (Kotovsky & Simon, ; P. J. Reber & Kotovsky, ), we studied the effect on rule discovery of having to plan actions or not in order to reach a goal state. This was done by asking participants to predict legal moves as in implicit learning tasks (Experiment 1) and by asking participants to make legal moves as in problem-solving tasks (Experiment 2). Our hypothesis was that having a specific goal state to reach has a dual effect on rule discovery. The first effect is positive and related to feedback from moves done in order to attain the goal: generalising the results of action and associating them to the conditions in which they were obtained allows discovery of the rule and learning it. The second effect is negative. In attempting to reach a specific goal, participants first tend to reduce the distance that separates the current state from the goal state (hill climbing) and so neglect the kind of exploration that facilitates rule and procedure discovery because this would seem to be a detour from the goal. Results show that having to plan actions improved performance in implicit learning tasks (Experiment 1), yet it impaired performance in problem-solving tasks (Experiment 2). Although implicit learning and problem solving are based on rule discovery, and entail noticing regularities in the material, in both cases, rule discovery processes appear to be task-dependent. 相似文献

A prevention model was applied to assess the protective effect of religion and church attendance against mental illness among respondents to the 1996 Utah Health Status Survey. Compared to Mormons that attend church weekly (active), less active Mormons, less active non-Mormons, and those with no religious preference, because of emotional problems, are at increased risk of accomplishing less than desired (model 1); having trouble doing work or other activities as carefully as desired (model 2); and seeking professional help (model 3). After adjusting for alcohol and tobacco use, education, income, physical activity, general health status, employment, body mass index, gender and age, only less active Mormons and those with no religious preference remained at significantly increased risk in model 3. Self-reported health status was the strongest predictor of mental health in each model. Active Mormons reported having the best health status and, consequently, the lowest levels of mental illness. 相似文献

Feedback-based learning declines with age. Because older adults are generally biased toward positive information (“positivity effect”), learning from positive feedback may be less impaired than learning from negative outcomes. The literature documents mixed results, due possibly to variability between studies in task design. In the current series of studies, we investigated the influence of feedback valence on reinforcement learning in young and older adults. We used nonprobabilistic learning tasks, to more systematically study the effects of feedback magnitude, learning of stimulus–response (S–R) versus stimulus–outcome (S–O) associations, and working-memory capacity. In most experiments, older adults benefitted more from positive than negative feedback, but only with large feedback magnitudes. Positivity effects were pronounced for S–O learning, whereas S–R learning correlated with working-memory capacity in both age groups. These results underline the context dependence of positivity effects in learning and suggest that older adults focus on high gains when these are informative for behavior. 相似文献

A memory scanning (Sternberg, 1966, 1975) task was administered to healthy young adults, older adults, and two groups of individuals with dementia of the Alzheimer's type (DAT) to determine age- and disease-related changes in the retrieval of information from short-term memory. Healthy older adults, in comparison to healthy young adults, displayed increases in both slopes and intercepts in memory scanning. Individuals at various stages of DAT (very mild, mild, moderate) displayed increases in both slopes and intercepts compared to nondemented age-matched control individuals. There was also some evidence that DAT individuals are more likely to engage in a self-terminating search instead of an exhaustive search of short-term memory. 相似文献

This paper examines the evolution of Jacques Lacan’s concept of mourning from his treatment of Hamlet in Seminar 6, “Desire and Its Interpretation,” to its transformation in the tenth Seminar on “Anxiety.” It is a transformation that occurs in tandem with Lacan’s reconception of anxiety as lack of the lack and his reshaped conception of the objet a as object/cause of desire. The key point is the way that Lacan’s renovated conception upends the common sense notion of mourning, that which assumes that suffering the death of a loved one means accommodating oneself to an absence where there was previously a presence. On the contrary, says Lacan, part of what is most deeply to be mourned is the lack in the Other around which the love relation was constructed. The paper concludes by asking to what extent Lacan’s account of mourning should be distinguished from those of both Hegel and Freud. 相似文献

The meaningful consideration of cultural practices, values and beliefs is a necessary component in the effective translation of advancements in neuroscience to clinical practice and public discourse. Society’s immense investment in biomedical science and technology, in conjunction with an increasingly diverse socio-cultural landscape, necessitates the study of how potential discoveries in neurodegenerative diseases such as Alzheimer disease are perceived and utilized across cultures. Building on the work of neuroscientists, ethicists and philosophers, we argue that the growing field of neuroethics provides a pragmatic and constructive pathway to guide advancements in neuroscience in a manner that is culturally nuanced and relevant. Here we review a case study of one issue in culturally oriented neuroscience research where it is evident that traditional research ethics must be broadened and the values and needs of diverse populations considered for meaningful and relevant research practices. A global approach to neuroethics has the potential to furnish critical engagement with cultural considerations of advancements in neuroscience. 相似文献

The measurement of pain depends upon subjective reports, but we know very little about how research subjects or pain patients produce self-reported judgments. Representationalist assumptions dominate the field of pain research and lead to the critical conjecture that the person in pain examines the contents of consciousness before making a report about the sensory or affective magnitude of pain experience as well as about its nature. Most studies to date have investigated what Fechner termed "outer psychophysics": the relationship between characteristics of an external stimulus and the magnitude and nature of pain experience. In contrast, Fechner originally envisioned that "inner psychophysics" should investigate the relationship between physiological states and subjective experience. Despite the lack of established research tradition, inner psychophysics has a potential utility in elucidating underlying mechanisms for the production of phenomenal self-report. We illustrate this, using causal modeling analyses of the accuracy of self-reported pain ratings from our laboratory. We submit that the results are inconsistent with representationalist assumptions. Converging trends from several domains of consciousness studies seem to suggest that we need to abandon the unquestioned doctrine of representationalism and search for a more viable framework for understanding the generation of subjective self-report. 相似文献
