The present study investigated the division of attention between different visual attributes, which is a cognitive function implicated in the selection of information in a given condition. To examine the underlying mechanisms, we focused on motion and color as visual attributes. In Experiment 1, performance on single- and dual-judgment for motion and color(More)
The minimum temporal thresholds for absolute motion detection were measured for sinusoidal grating patterns in foveal vision. Test patterns of relatively low temporal frequencies and low velocities were examined. The thresholds clearly decreased with test velocities rather than with test temporal frequencies. Modified velocity-time reciprocity was observed(More)
This study investigated the effect of exogenous spatial attention on auditory information processing. In Experiments 1, 2 and 3, temporal order judgment tasks were performed to examine the effect. In Experiment 1 and 2, a cue tone was presented to either the left or right ear, followed by sequential presentation of two target tones. The subjects judged the(More)
Perceived velocities during a brief period of exposure (< 1.2 s) were measured to examine how much time is necessary to perceive velocity as constant. Moving sinusoidal gratings were used as stimuli at relatively low velocities. At the beginning of each stimulus presentation, a moving pattern was perceived as stationary until a critical time had passed.(More)
Condensed systems of strongly interacting electrons are ideal for the study of quantum complexity. It has become possible to promote the formation of new quantum phases by explicitly tuning systems toward special low-temperature quantum critical points. So far, the clearest examples have been appearances of superconductivity near pressure-tuned(More)
The purpose of this study is to investigate the influence of spatial attributes of stimuli upon the estimation of duration time. Using magnitude estimation method, three tasks were imposed on seven undergraduate students. C (control) task was to estimate the duration of a static small circle, MF (moving-free) task was that of a moving pattern of randomly(More)
Two experiments were conducted to examine the processes of perceiving velocity changes of visual stimuli which were gradually accelerated. In Exp. I, using a rotating pattern of luminous spots as moving stimuli, the time required of the subject to perceive a velocity change was measured in slow, medium and fast positively accelerating conditions.(More)
