Kendall's rank order test for association between two variables is generalized to the case where the total sample is made up of several subgroups and the data on one or both variables consist of the rank order within each subgroup. The test involves no assumptions concerning scales of measurement, shapes of distributions, or relative level of excellence or amount of variability of the different subgroups. Two empirical examples indicate that the normal approximation to the exact test of significance can be considered adequate for most practical situations. Special consideration is given to the case of tied ranks. If ties occur in but one variable within any given subgroup, only a slight modification in procedure is needed. Extensive ties in both variables within subgroups lead to difficulties in determining the appropriate correction for continuity. 相似文献

Student mentoring is a common and often encouraged practice within graduate psychology and counseling programs. Although both mentors and protégés typically report multiple benefits from the practice, the mentoring relationship is also subject to a variety of ethical issues. The author presents a brief overview of professional literature regarding mentoring relationships, including key features and stages of development of these relationships, and then addresses potential ethical concerns. Guidelines and implications for ethical mentoring practice are also presented to encourage more specific attention to this vital component of counselor training. 相似文献

Little is known about how schizophrenia might affect how a mother responds to her infant, such as whether responding is reduced or impaired. The aim was to identify, from brief videotaped interactions, whether the responses of mothers with schizophrenia were fewer, less positive, more negative, and more ‘abnormal’ than mothers with affective disorder, and whether their infants (mean age: 15 weeks) lacked activity or initiation to which mothers could respond. Mothers with schizophrenia (N = 14) were as responsive as mothers with affective disorder (N = 31), but they showed markedly low positive responsiveness. Only the schizophrenia group exhibited non-responses as a result of being psychologically withdrawn from the interaction, and abnormal behaviors. Inconsistent to our hypothesis, infants in both groups showed similar levels of activity, initiative and negativity. The findings highlight the need for further research to examine the contribution of maternal response impairments to the developmental vulnerability of this genetically high-risk group. 相似文献

Evidence of group matching frequently takes the form of a nonsignificant test of statistical difference. Theoretical hypotheses of no difference are also tested in this way. These practices are flawed in that null hypothesis statistical testing provides evidence against the null hypothesis and failing to reject H-sub-0 is not evidence supportive of it. Tests of statistical equivalence are needed. This article corrects the inferential confidence interval (ICI) reduction factor introduced by W. W. Tryon (2001) and uses it to extend his discussion of statistical equivalence. This method is shown to be algebraically equivalent with D. J. Schuirmann's (1987) use of 2 one-sided t tests, a highly regarded and accepted method of testing for statistical equivalence. The ICI method provides an intuitive graphic method for inferring statistical difference as well as equivalence. Trivial difference occurs when a test of difference and a test of equivalence are both passed. Statistical indeterminacy results when both tests are failed. Hybrid confidence intervals are introduced that impose ICI limits on standard confidence intervals. These intervals are recommended as replacements for error bars because they facilitate inferences. 相似文献

Despite clinical sensitivity when listening to patients, analysts have not fared well in hearing and talking to each other with respectful open‐mindedness. Underlying factors are considered with particular focus on the interplay between self‐aimed forces of narcissism and outward‐aimed forces of curiosity. Included in examination of problems of collegial communication are limitations structurally inherent to the human mind (such as the need to abstract aspects of experience in order to focus attention plus the mind’s tendency to categorical thinking), those derived from individual psychology (such as vulnerability of self‐esteem), and those related to group dynamics (such as the problems attendant to new ideas and the allegiances they stir, parochialism and the development of radical schools, the competitiveness between schools). The contribution of cultural influences and the multiply determined uses of language are also highlighted. The core sense of smallness in the strangeness of the universe and in the presence of others is seen as a common thread. 相似文献

The utility of distinguishing between introjective hurt (feeling sad, engaging in selfblame, and wondering what one did wrong)
and retaliatory hurt (yelling at, blaming, confronting, and feeling angry toward the offender) was explored in a longitudinal
design of two months. Participants (N=51) were asked to describe a recent hurtful incident in survey format and complete subsequent measures of various behavioral
and emotional reactions, including hurt and forgiveness. Results suggested the stability and relative independence of the
two types of hurt and the differential significance of predictor variables (for example, apology) for each hurt type, both
simultaneously and over time. These results support the distinction between retaliatory and introjective hurt as they represent
distinct reactions with differential interpersonal outcomes. 相似文献

The present study examined the clock-speed modulating effects of acute cocaine administration in groups of male rats that received different amounts of baseline training on a 36-s peak-interval procedure prior to initial drug injection. After injection of cocaine (10, 15, or 20mg/kg, ip), rats that had received a minimal amount of training (e.g., or=180 sessions) prior to cocaine (15 mg/kg, ip) administration did not produce this "classic" curve-shift effect, but instead displayed a general disruption of temporal control following drug administration. Importantly, when co-administered with a behaviorally ineffective dose of ketamine (10mg/kg, ip) the ability of cocaine to modulate clock speed in rats receiving extended training was restored. A glutamate "lock/unlock" hypothesis is used to explain the observed dopamine-glutamate interactions as a function of timing behaviors becoming learned habits. 相似文献
