Sixty-hertz raster scan monitors provide relatively inexpensive solutions to problems associated with presenting complex visual stimuli. However, they restrict the user to displays in which stimulus characteristics cannot be changed more often than once every 16.67 msec. Calligraphic monitors allow very high frame rates, but not the generation of complex or chromatic images (unless very expensive monitors are purchased). A method is reported for increasing the frame rate of some raster monitors at the expense of the number of lines that are painted. Also, data relating to the influence of such a modification on visual performance is presented. 相似文献

In antiquity the healing role was usually performed by one person-a priest-physician. This also applied to hypnotism. As science emerged, eventually the roles of physician and priest were separated and performed by different persons. In the present case the roles of priest and physician were again united, resulting in significant improvement for the patient. Previously the separated roles had been ineffective.Edward M.

A software system is capable of recording eye position, reducing these data to a sequence of eye fixations, and immediately replaying this fixation sequence superimposed over the original stimulus. The replay can be controlled by the subject to produce various speeds, to pause, or to back up to earlier fixations. The purpose of the replay software is to enable the eye fixations to prompt a retrospective verbal protocol. Such a prompted protocol should reduce the forgetting and fabrication problems that are often associated with retrospective protocols. In a preliminary experimental test, the prompted protocol method yielded longer protocols and contained more words than those generated by either the concurrent or retrospective protocol methods. 相似文献

The present experiment was designed to examine the development of the cognitive representation of semantic categories. Response latencies on a classification task were compared for second, fourth, and sixth graders (8, 10, and 12 years of age, respectively) and college students. On each trial the subjects were presented with two pictures that represented either typical or atypical category exemplars. The two pictures were physically identical, nonidentical pictures from the same category, or pictures from different categories. One half of the trials were primed by presenting a category name in advance of the stimuli. In addition, stimulus degradation was manipulated in order to assess the locus of priming effects. A significant interaction of age × priming × typicality was found for physically identical stimuli. This interaction indicated that the nature of the internal representation of categories changed from the second graders to the adults. It was suggested that the second graders might weigh features inappropriately in generating semantic prototypes. The fact that stimulus degradation and priming did not interact at any age level for any of the match types indicates that priming affected a conceptual encoding stage rather than a perceptual encoding stage. 相似文献

The new federal law pertaining to the education of handicapped students requires that all students must be provided with an adequate educational program. Specific procedures and requirements are mandated. The implementation of the law places new demands on the total educational profession and also creates new opportunities to use counseling skills and new avenues for the continued advancement of humane values. 相似文献

A PDP-8/I was connected to an IBM/370 via telephone. Programs enable the PDP-8 to send data to practically any large-scale computer having timesharing capabilities. These programs can be used as models by others wishing to analyze data on a large computer. 相似文献

Theoretical analyses of pictorial perception have concentrated on the consequences of conflicting flatness and depth information in pictures, but have failed to consider the perceptual effects of the truncation of the visual field attendant on any pictorial display. The importance of this variable both for methods of testing pictorial information and for theory building was demonstrated. Under four different viewing conditions, adults were asked to scale the size and distance of five isoceles triangles at five different distances. The four conditions were unobstructed static monocular view, peephole view, view through a rectangular frame, and view of all the stimuli photographed in a slide. The slopes of the peephole, truncation, and slide conditions’ scaling functions were all significantly smaller than the slope of the untruncated Monocular condition, and the Y-intercepts were all greater. A decrease in over-constancy in the size functions indicated a similar effect for all three truncated conditions. Results are interpreted as supporting the hypothesis that truncation of the visual field, both in pictures and in peephole views of the real world, causes a frontal shift in the localization of the visible field, with a resultant compression of perceived size and distance. 相似文献
