A case of spontaneous initiation of movementTakao KUROKAWA, Ken MISHIMA1980 Volume 16 Issue 6 Pages 319-324

JOURNAL FREE ACCESSRespiratory rhythms were analyzed in relation to spontaneous initiation of fast flexion and extension of the forearm around the elbow joint. Forty-one right-handed healthy adults (twenty-seven males, 19-35 years old and fourteen females, 20-33 years old) were adopted as the subjects. Main findings are: 1) the duration of the inspiratory and/or expiratory phases varies in a subject-specific direction up to the movement onset, 2) conspicuous shortening of the expiratory phase duration occurs just before the movement onset in many subjects starting their movement in the inspiratory phase, 3) each subject has his particular pattern of distribution of initiation timings over a respiratory cycle, and 4) there is no respiratory phase in which the fast forearm movement is spontaneously initiated more frequently than in the other phase.View full abstractDownload PDF (815K) -

JOURNAL FREE ACCESSThis paper experimentally concerns the problem of whether a figure is represented in the human visual system by a gathering of its local features or by a global feature. When a figure is observed through a restricted small visual field, the representation of the figure is considered to be a chain composed of its local features. If the visual field becomes larger, the image of the figure changes; this means that the representation of the figure is changed by the change of the visual field size. An assumption was made that the local features in the chain did not change during the above process. Some other factors in the chain were assumd to have been changed under the influence of the visual field size. Two factors were proposed which seemed to satisfy the above assumption: One was the accuracy of the information which described the spatial relationship among local features, and the other was the amount of information stored in the short-term memory. The experiment, however, which examined whether these factors actually caused differences in the image showed that the assumption was invalid. This result suggests that a figure is represented by a global feature in our visual system.View full abstractDownload PDF (2978K) -

JOURNAL FREE ACCESSThis paper describes two experiments concerned with an auditory pursuit tracking. The stimuli are level-changing white noises. They consist of 60 and 61 constituent noises presented continuously, whose sound pressure levels are 42, 50, 58, 66, 74, 82 and 90dB. Exp. I had 4 stimulus-pattern conditions which differed from each other in the sequence and timing of appearances of 7 levels. One of these 4 conditions was used in Exp. II. Subject was instructed to push the button as quickly and correctly as possible, corresponding to the direction of intensity change of the stimulus. A response box was used with 7 buttons in a line in Exp. I, while in Exp. II with 9 including unused end buttons in order to remove the response cues at both ends. Reaction time (RT) was measured for the constituent noises. The results represent the relation between stimulus pattern and tracking difficulty. That is, mean RT is shortest when both direction and timing of intensity change of the stimulus are regular, and is longest when both are irregular. Also it means that the RT undergoes a systematic decrease with a corresponding increase in predictability the constituent noise has. This fact, especially the effect of predictability derived from the response cue, was confirmed in Exp. II.View full abstractDownload PDF (804K)
