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

The eight pieces constituting this Meeting Report are summaries of presentations made during a panel session at the 2011 Association for Practical and Professional Ethics (APPE) annual meeting held between March 3rd and 6th in Cincinnati. Lisa Newton organized the session and served as chair. The panel of eight consisted both of pioneers in the field and more recent arrivals. It covered a range of topics from how the field has developed to where it should be going, from identification of issues needing further study to problems of training the next generation of engineers and engineering-ethics scholars. 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

Despite implications that stranger fear is an important aspect of developing behavioral inhibition, a known risk factor for anxiety, normative and atypical developmental trajectories of stranger fear across infancy and toddlerhood remain understudied. We used a large, longitudinal data set (N = 1285) including multi‐trait, multi‐method assessments of temperament to examine the normative course of development for stranger fear and to explore the possibility that individual differences exist in trajectories of stranger fear development between 6 and 36 months of age. A latent class growth analysis suggested four different trajectories of stranger fear during this period. Stable, high levels of stranger fear over time were associated with poorer RSA suppression at 6 months of age. Rates of concordance in trajectory‐based class membership for identical (monozygotic) and fraternal (dizygotic) twins, along with associations between atypical stranger fear development and greater anxiety‐related maternal characteristics, suggested that individual differences in developmental trajectories of stranger fear may be heritable. Importantly, trajectories of stranger fear during infancy and toddlerhood were linked to individual differences in behavioral inhibition, with chronically high levels of stranger fear and sharp increases in stranger fear over time related to greater levels of inhibition than other developmental trajectories. 相似文献

The objective of this study was to investigate the presence of worry about personal moral attitudes and behaviors in two college samples, and to check associations with religiosity, age, gender, personality traits, and geographic region. The study sample was drawn from college students in Minneapolis, Minnesota (N?=?333) and Sydney, Nova Scotia (N?=?137). Instruments consisted of moral worry and religiosity questionnaires, and the Eysenck Personality Questionnaire. Principal-components analysis was used to develop components for the worry and religiosity scales, and MANOVA for correlations between variables. Moral worry emerged as a domain distinct from worry about practical issues. Moral worry was not related to religiosity, age, gender, or Eysenck personality traits. Whereas the US sample scored higher in religiosity than the Canadian sample, the Canadian sample scored higher on moral worry. The present study supports our previous work and that of others that worry about one's moral emotions and behaviors is an important aspect of daily life. As such, consideration should be given to including some inquiry about moral worries (guilt, shame, regret, remorse, and others) in psychiatric assessments. 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
