Anatomical and theoretical considerations, as well as experimental findings, have yielded conflicting points of view regarding the abilities of the right hemisphere in man to accomplish cross-modal transfer of information. Auditory—visual cross-modal matching (CMM) and association (CMA) abilities of the left and right hemisphere (LH and RH) were tested, using the Wada intracarotid sodium amytal technique. It was found that the RH performed slightly better on these tasks than the LH. These findings contrast with results of other techniques which indicate that the RH cannot perform CMM and CMA. 相似文献

Examples are presented in which it is either desirable or necessary to transform two sets of orthogonal axes to simple structure positions by means of the same transformation matrix. A solution is then outlined which represents a two-matrix extension of the general orthomax orthogonal rotation criterion. In certain circumstances, oblique two-matrix solutions are possible using the procedure outlined and the Harris-Kaiser [1964] logic. Finally, an illustrative example is presented in which the preceding technique is applied in the context of an inter-battery factor analysis.The work reported herein was supported by Grant S72-1886 from the Canada Council.

Two experiments investigated the hypothesis that short-term visual memory is based primarily on physical features of the visual input. Subjects were required to recall visually presented figures or the names of those figures presented either visually or aurally at a number of different retention intervals. Subjects shadowed words during the retention interval presented aurally in Experiment I and visually in Experiment II. In both experiments, figures were recalled better than names and no differences in recall of names were found due to presentation modality. Recall of both names conditions showed a steady decline across retention intervals whereas recall of figures remained at a relatively high level. These findings were interpreted as providing further support for the existence of short-term visual memory not subject to auditory recoding and based primarily on physical features of the input. It was suggested that such visual memory is limited in capacity so that input exceeding this capacity is recoded into an auditory-verbal-linguistic form. 相似文献

Four prominent oblique transformation techniques—promax, the Harris-Kaiser procedure, biquartimin, and direct oblimin—are examined and compared. Additionally, two newly-developed procedures, falling into the category designated as Case III by Harris and Kaiser [1964], are presented and included in the comparisons. The techniques are compared in light of their freedom from bias in the interfactor correlations, and their ability to yield clear simple structures, over many data sets—some constructed and some real—varying widely in terms of number of variables and factors, factorial complexity, and clarity of the hyperplanes. Results are discussed, and implications for practice are noted. 相似文献

This experiment investigated the positive-forgetting phenomenon with sentence material. Sets of sentences were presented to Ss with each sentence being cued “remember” or “forget” immediately following its presentation. To-be-remembered (TBR) sentences were found to be more accessible thanto-be-forgotten (TBF) sentences and uncued control sentences. Sentence connectedness was found to be an important determiner of the magnitude of the observed recall phenomenon; but differential sentence interest was not a significant factor. Using a multiple-choice recognition test, key words or phrases from the to-be-forgotten sentences were found to be equally available as key words or phrases from the to-be-remembered sentences. These results warrant an extention of Bjork’s (1970, 1972) selective-rehearsal and differential-grouping interpretation of the positive-forgetting phenomenon to encompass sentence material. Some implications of the findings for single-presentation information acquisition were noted. 相似文献

Direct physical aggression was related to three variables through a modification of the Buss (1961) “aggression machine” and procedure. There were two intensities of frustration and a control group established on the basis of the goal gradient principle. Aggression was either instrumental or noninstrumental in overcoming the frustration. Frustration was arbitrary (unreasonable) or nonarbitrary (reasonable). More aggression occurred under the instrumental condition than under the noninstrumental condition. The stronger frustration produced more aggression than the weaker frustration, but only when aggression had previously been experienced as instrumental. No more aggression occurred under the arbitrary frustration condition than under the nonarbitrary condition. The results were discussed in relation to the frustration-aggression hypothesis and the goal gradient principle. 相似文献
