Using the assumption of randomly parallel tests and concepts from generalizability theory, three signal/noise ratios for domain-referenced
tests are developed, discussed, and compared. The three ratios have the same noise but different signals depending upon the
kind of decision to be made as a result of measurement. It is also shown that these ratios incorporate a definition of noise
or error which is different from the classical definition of noise typically used to characterize norm-referenced tests.
Part of the work leading to this paper was accomplished while the authors were assistant professors at the State University
of New York at Stony Brook. 相似文献

Disbelief, lies, and manipulations have been objects of scholarly consideration from widely different perspectives: historical, sociological, philosophical, ethical, logical, and pragmatic. In this paper, these notions are re-examined in the framework of a Transactional Discourse Model which operates in terms of the location and relocation of various knowledge items within two sets of knowledge, A and B, representing two interlocators A and B, and two of their subsets Ca and Cb, which constitute the sets of the matters of A's and B's current concern. This approach reveals certain formal features shared by lies, disbelief, and manipulations that indicate that these three types of discourse behavior constitute a deviation from successful interpersonal communication as defined in the proposed model. The model, moreover, enables us to explicitly capture both the similarities and the differences of lies and manipulations with other pragmatic phenomena, such as jokes, impersonating, role-acting, memory failure, politeness expressions, and tact; the comparison suggests that certain modifications of Gricean conversational maxims may be in order. 相似文献

In a within-groups design, four obsessive-compulsive patients imagined four different types of scenes: (1) exposure to feared situations; (2) exposure to feared situations followed by engaging in ritualistic behavior: (3) engaging in ritualistic behavior without provocation; and (4) neutral situations. Each scene type was presented three times with order of presentation randomized. Beat-by-beat heart rate samples were taken during the visualization of each scene and converted to second-by-second heart rate. An examination of second-by-second heart rate for each scene type suggested that scenes involving exposure to feared situations elicited defensive responses (DR), whereas those that did not elicited orienting responses (OR). The implications of these results for compulsive behavior, the fear-reduction model and Sokolov's (1963) OR-DR model, are briefly discussed. 相似文献

The differential effects of massed and spaced sessions of exposure in vivo were investigated with 11 agoraphobics in a crossover design. Clients were randomly assigned to one of the following two groups: (a) 10 daily sessions followed by 10 weekly sessions, or (b) 10 once-weekly sessions followed by 10 daily sessions. The results indicated that both massed and spaced sessions of exposure in vivo effected changes in avoidance behavior and subjective anxiety of agoraphobics, massed practice being superior especially with respect to avoidance. It was suggested that the superiority of massed practice is due to the lack of opportunity to engage in avoidance or escape during short inter-session intervals. The relationship between subjective anxiety and avoidance were considered and the differences between clinical and statistical significance were discussed. 相似文献

Three ideas are basic to generative theory: (a) Subjects are assumed to attend to the relations among stimuli, extracting the transformations relating pairs of stimuli; (b) the set of abstracted transformations is decomposed or reduced to an elementary set of generators; (c) subjects use the elementary generators as the basis for judging similarity. The purpose of this paper is to illustrate these ideas with an experiment in which subjects were asked to rate the similarity between stimulus pairs. The stimulus materials consisted of the permutations of a 4-item pattern with the properties of a dihedral group which insured the existence of sets of elementary transformations. Three analytic techniques were used to determine the generator set of transformations abstracted by subjects. The first analysis consisted of a monotonic regression between dissimilarity ratings and the number of elementary generators of a given permutation. The residual variance of this monotone regression, suitably normalized, was used as a quantitative goodness-of-fit measure. For the stochastic analysis, cumulative distributions of dissimilarity ratings were obtained for permutations requiring one, two, or three generators. The idea was that permutations requiring fewer generators should be associated with distributions of lower dissimilarity values (higher similarity scores) as compared to permutations predicted to be transformationally more complex. The final analysis, a multidimensional scaling of dissimilarity ratings, converted subjects' ratings into spatial structures to determine whether individual subjects' ratings exhibited the predicted spatial arrangement. The monotone regression and stochastic analyses abstracted similar generator sets for individual subjects, some of which provided perfect fits to the data. Although the scaling analysis yielded similar estimates of generators, for some subjects, transformations with the same number of generators yielded unequal “cognitive” distances resulting in some-what deformed spatial structures for these subjects. It was concluded that the results generally supported a generative model as an approximation to subjects' representations of interstimulus relationships. 相似文献

This essay explores an increasingly popular genre of organized group travel in white mainline and emerging evangelical US Christianity I call “journeys to the margins”: trips centered on learning from marginalized persons for the traveler’s ethical formation. Drawing on ethnographic research with one case study, “Come and See Tours” to Israel/Palestine, I interrogate how the commodified form of these trips shape possibilities for ethical subjectivation. First, I demonstrate ways in which journeys to the margins market ethical transformation to American Christian consumers in the form of packaged moral narratives. Second, I focus on the paradoxical nature of journeys to the margins as simultaneously packaged commodities and ethical encounters. Finally, I use reformulations of freedom emerging from the anthropology of ethics to argue that possibilities for ethical subjectivation occur in moments when tour ideals come into tension with lived realities. 相似文献

The present study investigated the effect of threat of physical harm on the aggressive behavior of intoxicated and nonintoxicated subjects. Forty male undergraduates competed in a reaction time task in which they could deliver shock to an increasingly provocative opponent. In the threat condition, subjects could be hurt by the opponent (they wore a shock electrode), while in the no-threat condition, they could not be hurt by the opponent (the electrode was removed prior to the competition). The results indicated that under conditions of low provocation, the intoxicated subjects behaved more aggressively than the nonintoxicated subjects in both the threatening and nonthreatening condition. However, under conditions of increasing provocation, only the intoxicated subjects in the threatening condition increased their shock settings. 相似文献

We explored cross-sectionally the roles in bipolar spectrum symptomatology of two broad motivational systems that are thought to control levels of responsiveness to cues of threat and reward, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS). Undergraduate students (n = 357) completed questionnaires regarding (a) bipolar spectrum disorders [the General Behavior Inventory (GBI), a well-established clinical screening measure], (b) current depression and mania symptoms (the Internal State Scale; ISS), and (c) BIS/BAS sensitivities (the BIS/BAS scales). Validated cutoff scores on the GBI were used to identify individuals at risk for a mood disorder. It was hypothesized that, among at-risk respondents, high BAS and low BIS levels would be associated with high current mania ratings, whereas low BAS and high BIS would be associated with high current depression ratings. Multiple regression analyses indicated that, among at-risk individuals (n = 63), BAS accounted for 27% of current mania symptoms but BIS did not contribute. For these individuals, BAS and BIS were both significant and together accounted for 44% of current depressive symptoms. 相似文献
