The current study investigated the effect of instructions and stimulus discriminability on size-constancy responses and decision times in a task allowing separate evaluation of the effects of instructions and of dimensional choices by the subjects in the size-constancy task. Objective, perspective, or distance matches were influenced both by the instructions given the subject and by the relative discriminability of the stimuli in each dimension, so that subjects did not always successfully follow their instructions. Decision times were found to be fastest with perspective rather than objective or apparent instructions, but times taken to produce objective and perspective matches did not differ. Apparently, both objective and perspective judgments are available to the perceiver before a response is made, but instructions affect postperceptual response times. 相似文献

The relationship between adaptive regression and cognitive flexibility was explored in a group of 42 college students. Adaptive regression was measured with the Holt scoring system for the Rorschach. One type of cognitive flexibility was measured by Guilford's tests of divergent production (Word Fluency, Associational Fluency, and Alternate Uses) and a second type by Mednick's Remote Associates Test. Adaptive regression was found to be significantly positively related to the Remote Associates Test in males but not in females. Adaptive regression was found to be unrelated to divergent production tests. These relationships were not found to be mediated by Rorschach productivity or verbal intelligence. A two-stage process was proposed to account for the cognitive operations underlying adaptive regression and the Remote Associates Test. The first stage is seen as a generative (primary process) stage, while the second stage is seen as an evaluative (secondary process) stage. Possible reasons for sex differences were also discussed. 相似文献

Three independent groups of 8 subjects listened monaurally to a randomized list of 50 common and 50 rare words and responded ‘yes’ to rare words. Responses were analyzed for correct identifications of rare words. A 50:50 group heard an equal number of words in right and left ears and gave a small but non-significant right-ear superiority. A 66:34 group heard nearly twice as many words in the right ear as the left and gave a significant right-ear superiority. A 34:66 group heard nearly twice as many words in the left ear as the right and gave a significant left-ear superiority. Responses were also analyzed according to signal-detection theory. Implications are discussed for theories of ear advantages. 相似文献

This case study of an inter-university controversy over the publication of research from an interdisciplinary social science project on the forced migration and long-term internment of West Coast Japanese-Americans during World War II shows some of the difficulties of maintaining ownership of research materials. In this particular instance the junior employee was able to override his seniors' demand for control of the dissemination of research results by playing on the concerns about even appearing to suppress work for political reasons. The paper discusses conflicting norms of science and rhetorics of justification ranging from proprietary self-interest through "good science" to "the national interest" and onto "the needs of a free society." 相似文献

A subject's performance under a conditional-discrimination procedure defines conditional relations between stimuli: “If A1, then B1; if A2, then B2.” The procedure may also generate matching to sample. If so, the stimuli will be related not only by conditionality, but by equivalence: A1 and B1 will become equivalent members of one stimulus class, A2 and B2 of another. One paradigm for testing whether a conditional-discrimination procedure has generated equivalence relations uses three sets of stimuli, A, B, and C, three stimuli per set. Subjects learn to select Set-B and Set-C comparisons conditionally upon Set-A samples. Having been explicitly taught six sample-comparison relations, A1B1, A1C1, A2B2, A2C2, A3B3, and A3C3, subjects prove immediately capable of matching the B- and C-stimuli; six new relations emerge (B1C1, B2C2, B3C3, C1B1, C2B2, C3B3). The 12 stimulus relations, six taught and six emergent, define the existence of three three-member stimulus classes, A1B1C1, A2B2C2, and A3B3C3. This paradigm was expanded by introducing three more stimuli (Set D), and teaching eight children not only the AB and AC relations but DC relations also—selecting Set-C comparisons conditionally upon Set-D samples. Six of the children proved immediately capable of matching the B- and D-stimuli to each other. By selecting appropriate Set-B comparisons conditionally upon Set-D samples, and Set-D comparisons conditionally upon Set-B samples, they demonstrated the existence of three four-member stimulus classes, A1B1C1D1, A2B2C2D2, and A3B3C3D3. These larger classes were confirmed by the subjects' success with the prerequisite lower-level conditional relations; they were also able to select Set-D comparisons conditionally upon samples from Sets A and C, and to do the BC and CB matching that defined the original three-member classes. Adding the three DC relations therefore generated 12 more, three each in BD, DB, AD, and CD. Enlarging each class by one member brought about a disproportionate increase in the number of emergent relations. Ancillary oral naming tests suggested that the subject's application of the same name to each stimulus was neither necessary nor sufficient to establish classes of equivalent stimuli. 相似文献

This study attempted to dissociate in aphasic patients different aspects of grammatical capacity. Subjects were asked to evaluate sentences containing violations of agreements between pronouns and verbs. Agreements which are considered primarily structural in nature were violated (e.g., a surface object case like “them” placed in a surface subject sentential slot) while other violated agreements seemed to involve both structural and semantic information (e.g., lack of agreement between a pronoun and a verb in terms of the number of people performing the act). These violations were couched in one of three types of sentential frames which varied in terms of syntactic complexity (e.g., active declarative vs. passive syntactic voices). The results revealed that Broca's aphasics found agreement violations difficult to detect in complex syntactic frames. They were quite successful at detecting even violations of the largely structural “case” type of agreement, however, when couched in simpler syntactic frames. Fluent aphasics encountered more difficulty detecting violations of agreements involving both semantic and structural information than agreements which were primarily structural in nature, that is, regardless of the syntactic frame. These unique performance profiles suggest that Broca's aphasics may be agrammatic only with respect to certain aspects of a sentence's structure, and that fluent aphasics may also experience some selective—but different—grammatical deficits. 相似文献

Holland uses a hexagon to model relationships among his six types of vocational interests. This paper provides empirical evidence regarding the nature of the interest dimensions underlying the hexagon. Two studies are reported. Study 1 examines the extent to which two theory-based dimensions—data/ideas and things/people—fit 27 sets of intercorrelations for Holland's types. Three of the data sets involve the mean scores of career groups (total of 228 groups and 35,060 individuals); 24 involve the scores for individuals (total of 11,275). Study 2 explores the heuristic value of the data/ideas and things/people dimensions by determining whether they contribute to the understanding of why interest inventories work. Two data sets covering a total of 563 occupations are used to calculate correlations between the vocational interests of persons and the tasks which characterize the persons' occupations. Each occupation's principal work tasks are determined from job analysis data obtained from the U.S. Department of Labor. Study 1 results provide substantial support for the theory-based dimensions. Study 2 results suggest that interest inventories “work” primarily because they tap activity preferences which parallel work tasks. Counseling and research applications of the data/ideas and things/people dimensions are suggested and implications for interest assessment are noted. 相似文献
