The present study examined observers’ ability to discriminate canonical and dynamically anomalous collisions that were presented in either frictionless or frictional systems. Whereas previous research has provided qualitative demonstrations that dynamic information can be extracted from visual events, the current study provides a parametric assessment of observers’ sensitivity to dynamic invariants. Our findings indicate that observers are competent when viewing both familiar, terrestrial (frictional) systems and unfamiliar but computationally simpler, 0-G (frictionless) systems. Thus, our sensitivity to these dynamic invariants in visual events is robust in natural systems whose dynamic properties differ from those of the environment in which we evolved and developed.  相似文献

The experiment investigated the effects of Type A behavior, anger expression, and gender on perceptions of control and heart rate. Jenkins Activity Survey defined Type A and B subjects, categorized as either high or low in anger expression, were asked to recall, image, and generate self-referent statements about angry situations. State anger and heart rate were measured during all of the anger induction conditions, and ratings of imagery vividness and perceptions of control for self and others were taken following the recalled and imaged anger conditions. The results, with both the heart rate and self-report measures, indicated that the effects of the independent variables were interactive and situationally dependent. Type A behavior was associated with increased heart rate in two experimental conditions (mood anger and recalled anger), and, in one instance, this effect was amplified in male subjects (recalled anger). The self-report results yielded interactional effects that most commonly took the form of high anger expression, with male Type A's providing higher ratings of state anger, more vivid anger imagery, and lower perceived self-control ratings than did other categories of subjects. Taken together, these results suggest that anger expressiveness, particularly among males, amplifies the usual reactions attributed to Type A's, and that such effects are mediated by the threat of loss of control. Further, the observed interactive relationships limit the generalizability of A/B differences and raise definitional questions about Type A behavior.  相似文献

The absence of operational disaggregate lexicographic decision models and Tversky's observation that choice behavior is often inconsistent, hierarchical, and context dependent motivate the development of a maximum likelihood hierarchical (MLH) choice model. This new disaggregate choice model requires few assumptions and accommodates the three aspects of choice behavior noted by A. Tversky (1972, Journal of Mathematical Psychology, 9, 341–367). The model has its foundation in a prototype model developed by the authors. Unlike the deterministic prototype, however, MLH is a probabilistic model which generates maximum likelihood estimators of the aggregate “cutoff values.” The model is formulated as a concave programming problem whose solutions are therefore globally optimal. Finally, the model is applied to data from three separate studies where it is demonstrated to have superior performance over the prototype model in its predictive performance.  相似文献

Two experiments assessed infant sensitivity to figural coherence in point-light displays moving as if attached to the major joints of a walking person. Experiment 1 tested whether 3- and 5-month-old infants could discriminate between upright and inverted versions of the walker in both moving and static displays. Using an infant-control habituation paradigm, it was found that both ages discriminated the moving but not the static displays. Experiment 2 was designed to clarify whether or not structural invariants were extracted from these displays. The results revealed that (1) moving point-light displays with equivalent motions but different topographic relations were discriminated while (2) static versions were not, and (3) arrays that varied in the amount of motion present in different portions of the display were also not discriminated. These results are interpreted as indicating that young infants are sensitive to figural coherence in displays of biomechanical motion.  相似文献

The ability to recognize and analyze a personal legend in the conversation of an older person is a useful tool for the skilled, compassionate conversation partner. Having isolated the legend, the empathic listener can offer the teller of the legend the gift of an understanding, clarifying interpretation of its significance.Carolyn K. Dennis, M. Th., is assistant chaplain and program coordinator of the health care lay ministry training program at Gaston Episcopal Hospital, in Dallas, Texas.  相似文献

This project explores what dreams might reveal about the collective psyche’s response to the COVID-19 pandemic in its first year, before the development of vaccines. A brief survey, distributed to Jungian colleagues and organizations, and to various social media sites, invited people to submit online a dream related to the COVID-19 pandemic. Four hundred and thirty-six dreams were submitted. Forty additional Russian dreams were collected and submitted by Russian colleagues. Using qualitative research methods based on phenomenological hermeneutics, the researchers categorized and counted the range of COVID imagery. In addition, the researchers describe a range of psychic responses to the pandemic, including horror, grief, sickness, social discord, and violence, but also images of healing and transformation, increased sense of community, and spiritual renewal. Several healing nightmares are presented. Healing alchemical and anima/animus imagery is described. Twelve dreams are introduced and presented. It is concluded that the collective psyche, rooted in the Self, is a healing resource for social and cultural trauma. This project supports Beradt’s (1968) inspirational study of dreaming in Nazi Germany, as well as recent studies of COVID-related dreams and recent publications on the social nature of dreaming.  相似文献
