This paper reviews 15 statistics programs for the Macintosh. All are intended for student use, often in conjunction with a statistics course, and are available for under $100. Of the general-purpose programs, Data Desk and StatView offer the most appealing combination of features, Macintosh interface, and student-accessible manual. Minitab is also recommended, especially in situations where some students will be using Macs and others using PCs. In addition to the analysis-only programs, two other applications present interesting combinations of statistics and other features. DataSim offers outstanding data generation and experiment simulation along with very complete, and psychology-oriented, statistical analysis. HyperStat combines an entire statistics textbook in hypertext format with a complete data analysis package. Finally, for special situations where simple statistics are all that are required, InStat is recommended because of its tutorial features and very simple interface. 相似文献

The increase in legal regulation of psychiatric practice, malpractice litigation, number of mentally ill in correctional settings and concerns about the sometimes embarrassing quality of expert witness testimony has led to an heightened focus on training and credentialing of psychiatrists who work in these areas. The past 20 years has witnessed a growth of professional organizations, journals, accredited training programs and board certification. The paper outlines the nature of these programs and some of the dilemmas for the profession in establishing formal subspecialties. 相似文献

A model of individual differences that moderate attitude-behavior consistency was developed and tested in the context of predicting use consistency of the diaphragm. Variables hypothesized to moderate the attitude-behavior relationship included reactions to major life changes, the attitudes and opinions of others, sexual interest, locus of control, and the perceived susceptibility to pregnancy. Attitudes were conceptualized in terms of a Relative Contraceptive Utility (RCU), which was defined as the difference between the attitude toward the diaphragm and the attitude toward becoming pregnant. Women (N = 110) who attended family planning clinics in the New York Qty area and who used the diaphragm for an 8-month period were interviewed in the context of a 3-wave panel design. A threshold function between RCU and behavior was observed, such that when RCU was above an empirically derived cutoff, women tended to use the diaphragm consistently over an 8-month period. For women with RCUs below the cutoff, attitudes were unrelated to behavior. Inconsistency of diaphragm use for these latter women was best predicted by negative reactions to close friends' experiences with the diaphragm, low levels of perceived susceptibility to pregnancy, alcohol consumption, concern about becoming too old to have children, a preference for nonromantic sex, and the partner's unwillingness to refrain from sex if the women was not prepared. 相似文献

What's wrong with cross-cultural comparisons of subjective Likert scales?: The reference-group effect 总被引:9,自引:0,他引:9

Social comparison theory maintains that people think about themselves compared with similar others. Those in one culture, then, compare themselves with different others and standards than do those in another culture, thus potentially confounding cross-cultural comparisons. A pilot study and Study 1 demonstrated the problematic nature of this reference-group effect: Whereas cultural experts agreed that East Asians are more collectivistic than North Americans, cross-cultural comparisons of trait and attitude measures failed to reveal such a pattern. Study 2 found that manipulating reference groups enhanced the expected cultural differences, and Study 3 revealed that people from different cultural backgrounds within the same country exhibited larger differences than did people from different countries. Cross-cultural comparisons using subjective Likert scales are compromised because of different reference groups. Possible solutions are discussed. 相似文献

People in long-term romantic relationships possess relationship maintenance mechanisms designed to protect against the temptation of desirable relationship alternatives. The current research examined the link between relationship maintenance mechanisms and an index of neurologically based approach/avoidance motivation. Participants completed a line bisection task that yields measures of asymmetric activity in the right and left frontal cortices; such activity is thought to reflect people's level of approach/avoidance motivation. Compared to single participants, participants in committed relationships displayed relatively less left visual field bias on the line bisection task (indicative of greater left frontal cortical activation and greater cognitive avoidance motivation) in response to available, attractive opposite-sex targets. Decreased left visual field bias was particularly pronounced among individuals with moderate levels of relationship commitment — those expected to display the highest levels of relationship maintenance. These findings provide insight into perceptual, motivational, and neurological processes that may help people avoid tempting relationship alternatives. 相似文献
