The accuracy of abstracts in psychology journals 总被引:1,自引:0,他引:1
Harris AH Standard S Brunning JL Casey SL Goldberg JH Oliver L Ito K Marshall JM 《The Journal of psychology》2002,136(2):141-148
This article provides an empirically supported reminder of the importance of accuracy in scientific communication. The authors identify common types of inaccuracies in research abstracts and offer suggestions to improve abstract-article agreement. Abstracts accompanying 13% of a random sample of 400 research articles published in 8 American Psychological Association journals during 1997 and 1998 contained data or claims inconsistent with or missing from the body of the article. Error rates ranged from 8% to 18%, although between-journal differences were not significant. Many errors (63%) were unlikely to cause substantive misinterpretations. Unfortunately, 37% of errors found could be seriously misleading with respect to the data or claims presented in the associated article. Although deficient abstracts may be less common in psychology journals than in major medical journals (R. M. Pitkin, M. A. Branagan, & L. F. Burmeister, 1999), there is still cause for concern and need for improvement. 相似文献

Experiment 1 showed that laboratory-reared desert kangaroo rats, like domestic Norway rats, efficiently search for food on a radial arm maze (RAM) by avoiding revisiting arms within a trial. By placing an RAM on the floor so the animals could approach food from any direction, Experiment 2 tested whether efficient search by kangaroo rats was based on tactics of distance minimizing, central-place foraging, trail following, or meandering. In contrast to the dominant trail-following tactic of domestic Norway rats (Hoffman, Timberlake, Leffel, & Gont, 1999), kangaroo rats tended to distance minimize, whether maze arms were present or not. Experiment 3 indicated that kangaroo rats treated a floor configuration of eight food cups as two patches of four, based on beeline travel between patches and meandering within them. We conclude that similar performance in an elevated RAM by different species can be based on different tactics, and we suggest that a laboratory apparatus can be used to cast light on niche-related mechanisms. 相似文献

"Personal projects," as defined by B. R. Little (1983), were elicited from 600 community residents aged 70+, representing a broad range of health and illness. Factor analysis revealed 6 types of personal projects: activities of daily living, active recreation, other-oriented activities, intellectual activities, home planning, and spiritual moral activities. Background factors and health were shown to affect the number and type of projects reported. Most indices of personal projects were associated with positive affect and valuation of life. Only 1 was associated with depression. This confirms the differential association of personal projects to positive but not negative affect. Personal projects are seen as part of an open motivational system in which social position, cognitive ability, health, and positive mental health are mutually interacting members. 相似文献

Matthew Hoffman 《Jewish History》2005,19(1):65-78
The Russian Jewish intellectual, Chaim Zhitlovsky (1865–1943), a leading architect of secular Jewish culture and thought, was a central figure in the progressive Jewish intelligentsia of the late nineteenth and early twentieth century. In an essay written in 1927, Yidn un Yiddishkayt (Jews and Jewishness), he sought to define the secular essence of what he calls Yiddishkayt. This essay is not the first in Zhitlovskys long publicistic career in which he searches for new, secular definitions of Jewish identity and culture. But this essay differs, since it is marked by Zhitlovskys use of contemporary social scientific notions of race and racial traits to conceptualize what he believes constitutes Jewishness in a non-religious context, along with his adoption of the mystical Jewish concept of the pintele yid, the theory of an innate Jewishness embodied by a Jewish spark. Zhitlovskys desire to craft a truly secular theory of Jewish identity led him ironically to accept models of Jewish identity at odds with his stated larger vision. In turning to contemporary racial theory, as well as long nurtured mystical models of Yiddishkayt, Zhitlovsky reveals the wide range of ideological discourses that led him to innovative and controversial notions of modern Jewish identity. 相似文献

Hoffman L 《Journal of the American Psychoanalytic Association》2003,51(4):1219-1240
In this paper the author continues his study of conflicts over aggression in women, discussing the implications for contemporary theories of feminine psychology of observations of mothers in parent/child groups with their infants and toddlers. Many mothers experience conflicts over aggression (both in themselves and in their children) and become intolerant of their ambivalence toward their children. The author suggests that this observation provides an avenue that allows an integration of psychoanalytic ideas about maternity and childrearing with psychoanalytic understandings of women's conflicts about achievement in the social realm outside the home. In both roles, difficulties mastering conflicts with aggression may cause women to struggle profoundly, and to experience problems, in successfully negotiating their important life goals, whether the goals refer to their roles as effective mothers or their roles as effective individuals in the social sphere outside the home. Some women may demonstrate these difficulties in one sphere or the other, some in both, and others in neither. The author suggests on the one hand that we need to eliminate the concept of normality when considering the activities of women, and on the other hand that we need to normalize the omnipresence of ambivalence in the psychology of women. 相似文献

Parsing silhouettes: the short-cut rule. 总被引:2,自引:0,他引:2
Many researchers have proposed that, for the purpose of recognition, human vision parses shapes into component parts. Precisely how is not yet known. The minima rule for silhouettes (Hoffman & Richards, 1984) defines boundary points at which to parse but does not tell how to use these points to cut silhouettes and, therefore, does not tell what the parts are. In this paper, we propose the short-cut rule, which states that, other things being equal, human vision prefers to use the shortest possible cuts to parse silhouettes. We motivate this rule, and the well-known Petter's rule for modal completion, by the principle of transversality. We present five psychophysical experiments that test the short-cut rule, show that it successfully predicts part cuts that connect boundary points given by the minima rule, and show that it can also create new boundary points. 相似文献

Women's (N = 364) personal characteristics and gender role attitudes were examined in relation to their support for father involvement with children. The respondents completed measures of trust, attitudes toward women, hostility, self-esteem, and father involvement. Nontraditional gender role attitudes, positive ratings of their own interpersonal trust, and low hostility toward men were predictive of the respondents' support for father involvement. Participant demographics (including age, marital status, and number of children) were unrelated to their views of father involvement. Results indicate the importance of considering the characteristics and attitudes women bring to the co-parental relationship in the examination of factors influencing father involvement with children. Findings are discussed within the context of mothers' primary child-care and gatekeeping roles. 相似文献
