Spatial updating relies on an egocentric representation of space: Effects of the number of objects 总被引:1,自引:0,他引:1

Models of spatial updating attempt to explain how representations of spatial relationships between the actor and objects in
the environment change as the actor moves. In allocentric models, object locations are encoded in an external reference frame,
and only the actor’s position and orientation in that reference frame need to be updated. Thus, spatial updating should be
independent of the number of objects in the environment (set size). In egocentric updating models, object locations are encoded
relative to the actor, so the location of each object relative to the actor must be updated as the actor moves. Thus, spatial
updating efficiency should depend on set size. We examined which model better accounts for human spatial updating by having
people reconstruct the locations of varying numbers of virtual objects either from the original study position or from a changed
viewing position. In consistency with the egocentric updating model, object localization following a viewpoint change was
affected by the number of objects in the environment. 相似文献

We introduce the Berlin Affective Word List (BAWL) in order to provide researchers with a German database containing both
emotional valence and imageability ratings for more than 2,200 German words. The BAWL was cross-validated using a forced choice
valence decision task in which two distinct valence categories (negative or positive) had to be assigned to a highly controlled
selection of 360 words according to varying emotional content (negative, neutral, or positive). The reaction time (RT) results
corroborated the valence categories: Words that had been rated as “neutral” in the norms yielded maximum RTs. The BAWL is
intended to help researchers create stimulus materials for a wide range of experiments dealing with the emotional processing
of words. 相似文献

This study examined the relationship between the similarity and accuracy of team mental models and compared the extent to which each predicted team performance. The relationship between team ability composition and team mental models was also investigated. Eighty-three dyadic teams worked on a complex skill task in a 2-week training protocol. Results indicated that although similarity and accuracy of team mental models were significantly related, accuracy was a stronger predictor of team performance. In addition, team ability was more strongly related to the accuracy than to the similarity of team mental models and accuracy partially mediated the relationship between team ability and team performance, but similarity did not. 相似文献

This research addressed the issue of whether impressions of enclosure were more strongly influenced by amount of view covered by vertical boundaries (H1) or the presence of a boundary overhead (H2). There were three studies with totals of 48 stimuli and 142 respondents. Stimuli were balconies, swamps, and space stations. Effect sizes were reported for variables of boundaries below, in front of, and at the observers' sides, as well as amount of view covered by any boundary regardless of location with respect to the observer. Judged enclosure correlated at r =.80 for amount of view covered by vertical boundaries and r =.42 with the presence or absence of boundaries overhead, indicating that enclosure is more strongly related to vertical rather than overhead boundaries (alpha< .001). 相似文献

We describe some of the historical conditions that made possible Kabat-Zinn’s [(1990). Full catastrophe living: Using the wisdom of your body and mind to face stress, pain, and illness. New York: Delacorte] very successful use of mindfulness in his stress management program. The ground had been prepared by the nonjudgmental acceptance of people and symptoms by Humanistic psychotherapists, and by the increasing assimilation of Buddhist ideas into Western psychology and psychotherapy. In addition the word “mindfulness,” as the translation of the Pali sati, came to refer to both the manualized practice that provides the evidence for its efficacy in the hands of Kabat-Zinn and others, and the more complex process of clear comprehension and recollection that is described in his more discursive writings, and is similar to Ellen Langer’s use of “mindfulness” in her book of that name.
