| Research Abstract |
We studied the cross-modal (visual, tactile-propriocept) perception by conducting the psychological experiments under following three themes.
1.Studies on the type of reference frame that influence the stimulus-response compatibility (S-R compatibility)
To clarify the inner process of the S-R compatibility effect on the horizontal dimension, we conducted the experiments operating the relative right-left and absolute right-left dimension, and operating the relevance to task of these dimension. We found that the similarities of dimensions and the position of the target (stimulus) that the task makes the subjects to pay attention influence the process of the S-R compatibility effect on the horizontal dimension.
2.Cross-modal attentional blink phenomenon on visual and tactile perception
We examined whether the attentional blink would occur on the visual-tactile cross-modal perception. There was cross-modal interference between the visual task to the tactile task. (On this experiment, we use the first task on visual (to detect the letter defined by the color) and the second task on tactile (to detect the blank). It showed this interference effect was maintained for long time than the effect on the visual uni-modal task.
We had the other experiments by using the piezo tactile device. There was no attentional blink on the tactile uni-modal
3.Research on the perceptional learning process wearing the (right -left, top -down) reverse glass.
We examined the transfer of the long-range interaction across the hemifield by prism adaptation. We found it demonstrates large-scale plasticity in early visual system induced by reversed retinoptopic input. The global transfer can be achieved rapidly within a few days and it is long lasting.
We also conducted the psychological experiment on the side of cognition with top-down reversed figures.
