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

Piaget's theory of space perception in infancy is presented in the format of a hypothetico-deductive system. Eleven hypotheses are defined, regarding the perception of the agent of visual change; shape and size constancy; depth; and the perception of higher-order relationships among spatial elements. The proof Piaget offers for each hypothesis is presented in the following steps: behavioral evidence, interpretation in terms of inner states; inferences and generalizations. Presuppositions underlying the arguments are explicated. Critical notes are inserted whenever appropriate. Some general conclusions are briefly discussed. 相似文献

A classification of obsessive-compulsive phenomena based on the functional definition of obsessions as anxiety/discomfort producing and compulsions as anxiety/discomfort reducing is proposed. Based on the assumption of a functional equivalence between external and internal obsessive-compulsive behavior, four essential obsessive-compulsive forms are derived: (1) obssesions, (2) obsessions plus successful compulsions (anxiety/discomfort reducing), (3) obsessions plus obsessionalized compulsions (anxiety increasing), and (4) rituals consisting mainly of stereotyped, overt or covert behaviors (autonomous of anxiety/discomfort and/or obsessions). In addition, it is hypothesized that forms 1–4 represent developmental stages in the progress of obsessive-compulsive symptomatology, increasing in the order specified in complexity and severity and having varying prognostic implications. Finally, an attempt is made to suggest stage-specific behavioral treatment strategies. 相似文献

In this study a hierarchical model for the structure of vocational interests is proposed. Theoretical and methodological considerations, reanalysis of the C. E. Lunneborg and P. E. Lunneborg (Journal of Vocational Behavior, 1975, 7, 313–326) data, and an alternative interpretation of existing findings suggest that this model accounts for the interrelations among the vocational interest fields better than the hexagonal-circular models, or the four-factorial structure proposed by Lunneborg and Lunneborg (1975). The implications of this hierarchical model for vocational theory and some applications in vocational guidance are discussed. 相似文献

An aphasic patient was presented with a number of classification and identification tasks. The patient did better in classifying alphanumeric characters on various levels of abstraction than in identifying them. In another test the patient classified animals, birds, and flowers. His mistakes were interpreted as a consideration of characteristic features with a disregard of defining ones. The data are discussed in light of current research in cognitive psychology. 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

In an investigation of variations of a conciliatory strategy, 96 subjects, half female and half male, played a modified Prisoner's Dilemma in which their relative power, in terms of control over the other's outcomes, was less than, equal to, or greater than that of a simulated other. After 10 trials on which (s)he was 50% competitive, the other either did or did not send a handwritten note of general intent to be cooperative. In the second block of 10 trials, the other either was 100% cooperative or began with cooperation and stayed with it as long as the subject did not exploit. When the subject did exploit, the other made the competitive choice on the following trial as a form of retaliation, but followed this retaliation by a return to cooperation on the next trial so that there were never two consecutive competitive choices. During this second block, the simulated other always signaled in advance, with an explicit message, which choice (s)he was about to make. In a third block, the other was 100% cooperative in all conditions and sent no messages. As hypothesized, subjects whose power was equal to or less than that of the other were more cooperative in response to conciliation than were subjects whose power was greater than that of the other. Subjects who received the general note of intent were more cooperative than those who did not, but only in the equal and low power conditions. The subjects in the equal power condition who experienced retaliation were more cooperative than those who did not, but those in the unequal conditions tended to react negatively to retaliation. The results were discussed in terms of Osgood's (Peace Research Reviews, 1979, 8(2), 77–92) GRIT strategy and outcome control in interaction. 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
