The present study aimed to describe how a volunteer peer support service assists women with breast cancer, and provides guidelines for practitioners in the development and implementation of such programmes. A two‐phase evaluation of a breast cancer peer support program was undertaken to describe important attributes of the peer support intervention, the impact of the volunteer visit on women's self‐reports of anxiety, and key indicators of a successful volunteer visit. Phase 1 included focus groups with 57 women previously treated for breast cancer. Phase 2 included a survey of 245 women also treated previously for breast cancer and visited by a Breast Cancer Support Volunteer. The key aspect of the peer support process was the bond of common experience leading to a decrease in social isolation, an increase in optimism about the future and reassurance about personal reactions and femininity. It is recommended that peer support programmes should aim to time support visits to coincide with the time when patient support needs are highest, that volunteers need to be recruited from a range of backgrounds and matched to patients most similar to them in way of life, and that peer support services should be embedded in a broad network of community support services.

ObjectivesThere is a need to develop more effective physical activity (PA) promotion programs for college women. Theory and evidence suggest that perceptions of the social environment play a role in college women’s PA, though little is known about how these perceptions are associated with PA at the day level. The goal of this study was to examine relations between changes in college women’s daily social perceptions and objectively assessed PA over seven days.DesignDaily diary method.MethodCollege women (n = 80, MAge = 20, MBMI = 23.1 kg/m2) wore Fitbit wristbands and completed daily self-reports of (1) the quantity and perceived intensity of their social interactions (positive/negative), and (2) the occurrence of social comparisons (based on appearance/health/status) for seven days.ResultsMultilevel models showed daily variability in predictors and outcomes (ps < 0.0001), as well as relations between within-person changes in social perceptions and PA. Increases in negative interactions (particularly those with friends) were consistently associated with decreases in daily PA, whereas increases in positive interactions showed limited relations (srs = −0.22-0.34). Days with health comparisons were days with greater PA for women who had stronger overall interest in comparisons, but were days with less PA for women with weaker overall interest (srs = 0.22–0.33). PA did not differ between days with vs. without appearance comparisons.ConclusionsSocial perceptions show meaningful day-to-day variability and relations with college women’s daily PA, and specific associations may be useful for improving tailored interventions for college women. 相似文献

Relational Frame Theory posits that complex language develops through arbitrarily applicable relational networks, with potential implications for individuals with autism. Responding relationally based on comparison occurs when participants respond to any number of comparative properties, such as “bigger” or “faster.” Experiment 1 established two 3-member comparative networks, in which a stimulus A was conditioned as “bigger” or “faster” than a stimulus B, and the stimulus B was conditioned as “bigger” or “faster” than a stimulus C in 2 children with autism. Both participants met the mastery criterion for the trained relations and demonstrated the emergence of the untrained combinatorially entailed A–C and C–A relations. The participants could also match the arbitrary A stimuli with larger or faster objects and the C stimuli with smaller or slower objects. The results were replicated in Experiment 2 with the same participants, where a 5-member relational network was established for the bigger/smaller relation. 相似文献

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade-offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold-based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non-decreasing thresholds. Decreasing threshold strategies that “front-load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration. 相似文献

Speakers of English frequently associate location in space with valence, as in moving up and down the “social ladder.” If such an association also holds for the sagittal axis, an object “in front of” another object would be evaluated more positively than the one “behind.” Yet how people conceptualize relative locations depends on which frame of reference (FoR) they adopt—and hence on cross-linguistically diverging preferences. What is conceptualized as “in front” in one variant of the relative FoR (e.g., translation) is “behind” under another variant (reflection), and vice versa. Do such diverging conceptualizations of an object's location also lead to diverging evaluations? In two studies employing an implicit association test, we demonstrate, first, that speakers of German, Chinese, and Japanese indeed evaluate the object “in front of” another object more positively than the one “behind.” Second, and crucially, the reversal of which object is conceptualized as “in front” involves a corresponding reversal of valence, suggesting an impact of linguistically imparted FoR preferences on evaluative processes. 相似文献

Differences in the perceived usefulness of five multiple-attribute decision support systems versus a basic spreadsheet are empirically assessed. Twenty-four college faculty members participated in a repeated measures experiment in which they used decision support software for personal computers to analyse semistructured multiple-attribute problems. The software packages employed were Criterium, Expert Choice, Logical Decision, VIMDA, VISA and the spreadsheet package Quattro Pro. A questionnaire was developed to assess user-friendliness of the software, confidence in the procedure implemented by the software, and users’ confidence in their results when employing the decision aids. Time to reach a decision was also measured. Significant differences were fund in the overall way users ranked these aids, in the perceived user-friendliness and the confidence in procedure among aids, and in the time it took to arrive at a result. Comments from users are also reported. © 1997 John Wiley & Sons, Ltd. 相似文献

The Universal Declaration of Human Rights is a general legislative framework for democratic societies. Studying the social representations of these basic human rights helps to explain how people understand and assess the basic rights and how these rights relate to everyday life. Over 400 Czech university students rated the 30 articles of the Declaration of Human Rights on various scales (degree of understanding, personal relevance, consequences for individual responsibility, for government, political parties, etc.). A semantic space was identified in which concepts (i.e. the Articles of the Declaration) could be located. A typology (clusters) of articles was then established within that semantic space. A factor analysis of the scales resulted in a two-dimensional solution (‘positive attitude’ and ‘personal influence’). Five clusters of assessed articles were identified within this semantic space.

Use of numerical symbols by the chimpanzee (Pan troglodytes): Cardinals, ordinals, and the introduction of zero 总被引:8,自引:8,他引:0
An adult female chimpanzee with previous training in the use of Arabic numerals 1–9 was introduced to the meaning of "zero"
in the context of three different numerical tasks. The first two were cardinal tasks where the subject was required either
to select numerals corresponding to the number of items presented on a computer screen (productive use of numerals) or to
match sets of the appropriate size to numerals presented as samples (receptive use). The third task addressed the ordinal
meaning of the same symbols where the subject was required to respond to numerals sequentially, arranging them into an ascending
series. The subject mastered the recognition of the meaning of zero in all three tasks. However, details of her usage of the
symbol revealed that transfer of the meaning between different kinds of tasks was incomplete, suggesting that the level of
abstraction characteristic of human numerical ability was not attained in the chimpanzee. Over the course of acquisition leading
to the high levels of accuracy eventually observed, the newly introduced zero appeared to shift along the length of a continuous
numerical scale toward the lower end, while confusions with 1 remained the most frequently encountered mistakes. Such patterns
of error thus suggest that Ai's understanding of the meaning of zero in relation to the rest of the number symbols was not
consistent with an "absence of items versus presence of items" scheme.

Canadian university students (n=48) solved simple addition problems in a true/false verification task with equations in digit format (3+4=8) or written English format (three+four=eight). Participants reported their solution strategy (e.g. retrieval or calculation) after each trial. Reported use of calculation strategies was much greater with word (41%) than digit stimuli (26%), and this difference was exaggerated for numerically larger problems. Word-format costs on reaction time (RT) were correspondingly greater for large than for small problems, but this Format×Size RT effect was bigger for true than for false equations. The results demonstrate that surface format affects central, rather than only peripheral, stages of cognitive arithmetic. 相似文献

The primary purpose of the present study was to evaluate the internal consistency and construct validity of the Danish translation of Zuckerman's Sensation Seeking Scale (SSS). The secondary aim was to extend the range of psychological variables and behaviors that have been related to sensation seeking. The sample consisted of 691 subjects (363 males and 328 females) with a mean age of 31.7 years. The internal consistency of the scales was evaluated by coefficient alpha and intercorrelations among the five scales derived from the SSS were computed. Information on other variables was collected through standardized tests as well as questionnaires and interviews developed especially for this study. The results showed that the Danish SSS is a psychometrically sound instrument and revealed the relationship between sensation seeking and a broad spectrum of psychological traits and behaviors: socioeconomic status, academic achievement, intelligence, personality, smoking, alcohol and drug use, sexuality, driving and public transportation violations, and leisure time activities. Thus, this study confirmed and expanded the findings of many previous studies, while the results supported the validity of the Danish SSS and corroborated the usefulness of the concept of sensation seeking. 相似文献
