The sensitivity of an indirect method of measuring perceived distance was compared in two experiments with the direct procedure of eliciting verbal reports of distance. Perceived distance was varied by varying the oculomotor cues to object distance. The indirect method, called the “adjustable pivot method,” uses an apparatus that physically moves the stimulus object laterally concomitantly with the lateral motion of the head. The magnitude and direction of this concomitant motion determines the distance of the point around which the direction of gaze to the object rotates (the pivot distance) as the head is moved. The pivot distance at which the object appears stationary with head movement measures the apparent distance of the object. Both types of measures were found to vary systematically with the oculomotor distance of the object for points of light (Experiment 1) and extended objects (Experiment 2). A previous study has shown that the adjustable pivot method avoids cognitive errors that can distort verbal reports of distance. The present study, by demonstrating the discriminative capability of this method under conditions in which differences in perceived distance were expected to occur, provides clear evidence that the adjustable pivot method is a sensitive and useful procedure for measuring perceived distance. 相似文献

The examination of theorizing and techniques for scientific language analysis applied to ‘history’ clearly generalizes to imply a domain of applicability potentially coextensive for behavioral scientists with the scope of cultural behavior. It is argued that the computer and related science and technology are moving toward a relationship vis-à-vis symbolic acts analogous to microscopy for the ‘sub-visual’ in scale and telescopes for astronomic phenomena. Content analysis is one of the points of departure, as also contemporary syntactic analysis, from which present ideas and algorithms have moved on. How ‘far’ — both at present and in prospect — is the subject of these articles. 相似文献
