The information content of panoramic images II: view-based navigation in nonrectangular experimental arenas 总被引:2,自引:0,他引:2

Two recent studies testing navigation of rats in swimming pools have posed problems for any account of the use of purely geometric properties of space in navigation (M. Graham, M. A. Good, A. McGregor, & J. M. Pearce, 2006; J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, 2004). The authors simulated 1 experiment from each study in a virtual reality environment to test whether experimental results could be explained by view-based navigation. The authors recorded a reference image at the target location and then determined global panoramic image differences between this image and images taken at regularly spaced locations throughout the arena. A formal model, in which an agent attempts to minimize image differences between the reference image and current views, generated trajectories that could be compared with the search performance of rats. For both experiments, this model mimics many aspects of rat behavior. View-based navigation provides a sufficient and parsimonious explanation for a range of navigational behaviors of rats under these experimental conditions. 相似文献

This study investigated the contribution of child characteristics and parenting environment to the relationship between family SES/demographic characteristics and maternal language to infants. 1157 children were drawn from a representative sample of 1292 infants born to mothers in rural Appalachian counties and rural counties in southern minority U.S. communities. Mothers and their 6–8 month old babies were videotaped at home while talking about a wordless picture book. Mothers' language output and complexity were analyzed. Child temperament, age, and parenting environment (knowledge of child development and observed mother–child engagement) were predictors of maternal language. Furthermore, their inclusion reduced the magnitude of the association between demographic characteristics and maternal language. Tests of mediation suggested that the parenting environment partially mediates the relationship between SES/demographic characteristics and maternal language. Findings are discussed with respect to identifying proximal processes that explain how SES may exert its influence on the language of young children. 相似文献

Multiple methods were used to explore the character, contexts, and correlates of generativity among 41 men aged 45–55. Generativity in the role of worker was unrelated to generativity in men’s roles as father, citizen and ‘leisurite’. Individuals who were generative in their work reported greater job satisfaction and subjective career success. These associations were stronger for generativity targeting societal well-being and fellow-workers’ growth than for creative/productive generativity. As some theorists have argued, therefore, nurturant forms of generativity may be more adaptive in mid/late career than other varieties, and more indicative of psychosocial maturity. The status of creativity/productivity within the generativity construct seems problematic. Our findings offer qualified support for McAdams and de St Aubin’s (McAdams, D.P., & de St Aubin, E. (1992). A theory of generativity and its assessment through self-report, behavioral acts, and narrative themes in autobiography. Journal of Personality & Social Psychology, 62 (6), 1003–1015) contention that generativity is expressed differentially in the domains of concern, commitment and action, and that the different relationships of these generativity domains to third variables can be interpreted in meaningful ways. 相似文献

Attention capture by faces 总被引:2,自引:0,他引:2
We report three experiments that investigate whether faces are capable of capturing attention when in competition with other non-face objects. In Experiment 1a participants took longer to decide that an array of objects contained a butterfly target when a face appeared as one of the distracting items than when the face did not appear in the array. This irrelevant face effect was eliminated when the items in the arrays were inverted in Experiment 1b ruling out an explanation based on some low-level image-based properties of the faces. Experiment 2 replicated and extended the results of Experiment 1a. Irrelevant faces once again interfered with search for butterflies but, when the roles of faces and butterflies were reversed, irrelevant butterflies no longer interfered with search for faces. This suggests that the irrelevant face effect is unlikely to have been caused by the relative novelty of the faces or arises because butterflies and faces were the only animate items in the arrays. We conclude that these experiments offer evidence of a stimulus-driven capture of attention by faces. 相似文献

Recent evidence suggests that viewing a static prime object (a hand grasp), can activate action representations that affect the subsequent identification of graspable target objects. The present study explored whether stronger effects on target object identification would occur when the prime object (a hand grasp) was made more action-rich and dynamic. Of additional interest was whether this type of action prime would affect the generation of motor activity normally elicited by the target object. Three experiments demonstrated that grasp observation improved the identification of grasp-congruent target objects relative to grasp-incongruent target objects. We argue from this data that identifying a graspable object includes the processing of its action-related attributes. In addition, grasp observation was shown to influence the motor activity elicited by the target object, demonstrating interplay between action-based and object-based motor coding. 相似文献

The present study examines long-term correlated change in personality traits in old age across a time period of 12 years. Data from the Interdisciplinary Study on Adult Development were used to investigate different aspects of personality change and stability. The sample consisted of 300 adults ranging from 60 to 64 years of age at Time 1. Personality was measured with the NEO Five-Factor Inventory. Longitudinal structural stability, differential stability, change in interindividual differences, mean-level change, and correlated change of the 5 personality traits were examined utilizing structural equation modeling. After having established strict measurement invariance, factor variances in Openness to Experience and Conscientiousness were found to be different across testing occasions, implying variant covariation patterns over time. Stability coefficients were around .70, indicating high but not perfect differential stability. The amount of interindividual differences increased with respect to Openness to Experience and Conscientiousness. Both mean-level change and stability in personality were observed. Eventually, except for Neuroticism, a number of medium effect-sized correlations among changes in personality traits emerged, implying that personality changes share a substantial amount of commonality. 相似文献

We examine in detail three classic reasoning fallacies, that is, supposedly ``incorrect' forms of argument. These are the so-called argumentam ad ignorantiam, the circular argument or petitio principii, and the slippery slope argument. In each case, the argument type is shown to match structurally arguments which are widely accepted. This suggests that it is not the form of the arguments as such that is problematic but rather something about the content of those examples with which they are typically justified. This leads to a Bayesian reanalysis of these classic argument forms and a reformulation of the conditions under which they do or do not constitute legitimate forms of argumentation. 相似文献

A case study of six teachers cooperating to improve a teacher’s teaching showed the dynamics of the group problem-solving
process. An analysis of their verbal interactions showed the importance of shared understanding to successful group problem
solving. The cooperative group structure helped members resolve cognitive conflicts and build group understanding. During
this process, the members’ past teaching experiences and knowledge contributed to their conceptualization of the teacher’s
teaching problems and their proposed solutions to improve the teacher’s teaching.
Tsz Cheung Lam graduated from the Department of Educational Psychology at the Chinese University of Hong Kong in 2004 and obtained his Master
of Education degree. His research interests lie primarily on cooperative learning and problem solving. As a primary school
teacher in practice, he is now studying part-time for another master degree in data science at the Department of Statistics
of the Chinese University of Hong Kong. 相似文献

There is a persisting tendency in attempts to define spirituality, to adopt a dualistic point of view which sees the spirit as somehow impenetrably inner, innate and introspectively perceived, interacting with the outer world through the body. As well as a strong intuitive sense of the correctness of this philosophical point of view, it also is supported by psychotherapeutic perspectives that speak of the private inner being. In this paper I will argue that this view is logically, epistemologically, morally, and psychologically problematic. It will be argued that the concept of an inwardness to our mental life can be distinguished from the view of that life as interior. The perspective that we have of our inward selves is learned and conditional upon a sense of an outer self, functioning and communicating in the public world. Rather than an ego centric conceptualization of spirituality based on the idea of the spirit as inner and logically inaccessible, I we might adopt a sociocentric perspective in which the supremacy of the ego is dissolved in favour of an understanding in which we see ourselves as part of the social and natural outer world in which we exist. 相似文献

An expression-induction model was used to simulate the evolution of basic color terms to test Berlin and Kay's (1969) hypothesis that the typological patterns observed in basic color term systems are produced by a process of cultural evolution under the influence of biases resulting from the special properties of universal focal colors. Ten agents were simulated, each of which could learn color term denotations by generalizing from examples using Bayesian inference, and for which universal focal red, yellow, green, and blue were especially salient, but unevenly spaced in the perceptual color space. Conversations between these agents, in which agents would learn from one another, were simulated over several generations, and the languages emerging at the end of each simulation were investigated. The proportion of color terms of each type correlated closely with the equivalent frequencies found in the World Color Survey, and most of the emergent languages could be placed on one of the evolutionary trajectories proposed by Kay and Maffi (1999). The simulation therefore demonstrates how typological patterns can emerge as a result of learning biases acting over a period of time. 相似文献
