This study investigated the responses of 14 giant pandas (Ailuropoda melanoleuca) to 5 enrichment items (3 manipulable objects, 2 feeding devices) that possess different properties affording varying behavioral opportunities. Enrichment items were quantitatively described by using 12 properties. Pandas displayed no preferences among the 5 enrichment treatments, all of which had similar positive effects on behavioral measures of well-being (behavioral diversity, stereotypy). However, each item promoted a distinct behavioral profile, readily mapped onto the enrichment's properties. These results suggest that it may be important to stimulate behavioral diversity but that specific behaviors or enrichment properties are not required. The unique behavioral topography seen with these enrichments also suggests that providing multiple enrichments with varying properties will maximize overall behavioral diversity. 相似文献

Semantic features have provided insight into numerous behavioral phenomena concerning concepts, categorization, and semantic
memory in adults, children, and neuropsychological populations. Numerous theories and models in these areas are based on representations
and computations involving semantic features. Consequently, empirically derived semantic feature production norms have played,
and continue to play, a highly useful role in these domains. This article describes a set of feature norms collected from
approximately 725 participants for 541 living (dog) and nonliving (chair) basic-level concepts, the largest such set of norms developed to date. This article describes the norms and numerous statistics
associated with them. Our aim is to make these norms available to facilitate other research, while obviating the need to repeat
the labor-intensive methods involved in collecting and analyzing such norms. The full set of norms may be downloaded from

This study prospectively examined body image in a community sample of women smokers (N = 141, 89% European–American, M age = 39.5, M BMI = 25.5) participating in a 12-week randomized smoking cessation trial. Participants completed measures assessing subjective and perceptual aspects of body image. Regression analyses showed that subjective body image was predictive of smoking rate at the end of treatment. A MANCOVA revealed that perceptual body image (body size estimation) significantly predicted smoking cessation. Quitting smoking actually worsened body image, although these results were no longer significant after controlling for weight gain. Results support the theory that a negative body image may hamper cessation attempts. In addition, weight gain during smoking cessation may adversely impact body image and lead to an increased risk for relapse. 相似文献

A: Excuse me, but we're just trying to find the right bus that takes us to the boat for Upolu. We were told that it stops
here in front of the village store, but we've been waiting since 9 o'clock this morning and we'd like to know if there is
going to be a bus before this evening or if we'll have to wait until tomorrow for a bus.
I: Yes. 相似文献

When an object A moves toward an object B until they are adjacent, at which point A stops and B starts moving, we often see a collision--ie we see A as the cause of B's motion. The spatiotemporal parameters which mediate the perception of causality have been explored in many studies, but this work is seldom related to other aspects of perception. Here we report a novel illusion, wherein the perception of causality affects the perceived spatial relations among two objects involved in a collision event: observers systematically underestimate the amount of overlap between two items in an event which is seen as a causal collision. This occurs even when the causal nature of the event is induced by a surrounding context, such that estimates of the amount of overlap in the very same event are much improved when the event is displayed in isolation, without a 'causal' interpretation. This illusion implies that the perception of causality does not proceed completely independently of other visual processes, but can affect the perception of other spatial properties. 相似文献

Matching photos of famous people's faces with their names was as fast with photos that had eyebrows masked by adhesive plaster as with unretouched original photos. But matching was slower with photos that had eyebrows erased and replaced with adjacent skin texture and colour than with original photos. The conjecture that erasure impairs recognition because it alters a face's configuration was examined by repeating the experiment with the photos shown upside down, the rationale being that because configural information is difficult to encode from inverted faces the erasure effect should diminish. With inverted faces, matching was no different for original, eyebrows-masked, and eyebrows-erased photos. Eyebrows appear to be less important for face recognition as informative parts and features than as sources of information about a face's configuration. 相似文献

Since 1915, statisticians have been applying Fisher'sZ-transformation to Pearson product-moment correlation coefficients. We offer new geometric interpretations of this transformation. 相似文献

In 2 experiments, the authors investigated phonologically mediated priming of preexisting and new associations in word retrieval. Young and older adults completed paired word stems with the first word that came to mind. Priming of preexisting associations occurred when word-stem pairs containing homophones (e.g., beech-s____) showed more completions with the target (e.g., sand) relative to unrelated pairs (e.g., batch-s____), with more priming for subordinate than for dominant homophones. Priming occurred for new associations independent of dominance such that word-stem pairs containing homophones (e.g., beech-l____ and beach-l____) were completed with the same word (e.g., laugh) more often than unrelated pairs (e.g., beech-l____ and batch-l____). No age differences in phonologically mediated priming were found for either type of association, suggesting age equivalence in the use of bottom-up phonological connections. 相似文献
