Article: Effects of self-motion on attention in real 3D space.
[show abstract] [hide abstract]
ABSTRACT: Human behavioral space is three-dimensional (3D), and when moving through 3D space individuals selectively allocate their attention to acquire necessary information. This study aimed to examine the characteristics of attention in real 3D space when observers were moving forward. In static and self-motion situations, relative and absolute cues were used. Results indicated that internal representation for allocation of attention in 3D space is in depth-aware mode whether in static or moving condition. Moreover, near superior asymmetrical switching of attention is more strongly manifested under moving than under static conditions. Our findings indicate that focusing of attention by relative and absolute cues is maintained in self-motion, and that allocation of attention during movement is more viewer-centered than when observers are static.Acta psychologica 07/2009; 131(3):194-201. · 2.19 Impact Factor -
Article: Attentional processing of location and color cues during driving.
[show abstract] [hide abstract]
ABSTRACT: Studies have shown that prior information concerning the spatial location of a subsequent target facilitates the selection of that target for further visual processing in three-dimensional (3-D) space. Using Posner's cuing paradigm, our work examined the reaction time of drivers when cue duration and peripheral environment luminance was changed, and explored the effect color and location on reaction time. Experiment 1 showed that reaction time was not affected by cue duration, and that shifts of attention operated more efficiently for cue location validity. Experiment 2 showed that there was no main effect of background luminance on reaction time. Experiment 3 showed that location produces a greater effect than color.Scandanavian Journal of Psychology 04/2009; 50(4):293-300. · 1.52 Impact Factor -

Conference Proceeding: The Study of Characteristic of Attention in Depth of Drivers in Supposed Traffic Environment

ABSTRACT: The number of traffic accidents keeps increasing in China with the development of road traffic environments. From statistical data, it is well known that there are a lot of accidents at twilight time. The cause of these accidents is depending upon the shift of attention in depth according to the changes in twilight. Investigations of the characteristic of shift of attention in depth in three-dimensional (3-D) space by changing periphery luminance when the subjects were moving forward were carried out using a three-dimensional attention measurement system in order to examine the effects of luminance environment on the shift of attention. In the experiments, two kind of luminance condition were used, brightness condition and twilight condition. In each experiment, there were three kinds of clue condition: valid, invalid and neutral condition. It was the location of the appearance of the target relative to the fixation point. Observer moved forward at 0.44 m/s speed, and illuminance were 480~6801times and 95~1351times in the experimental device inner. The subject's task was to judge whether the target presented nearer than fixation point or further than it. Reaction times of the subjects on the clue were measured. As the results, it was clarified that (1) the visual adaptive ability of the subjects had a individual difference, (2) the shift of attention was faster from far to near than from near to far, (3) the reaction time was effected by the attention moved distance, (4) brightness has had very great influence upon the delay of reaction time of the drivers in traffic environment, and the delay of reaction time depended on the quantity of attention moved.Complex Medical Engineering, 2007.

Article: Measuring of Driver Reaction Time with Color Detection Task
[show abstract] [hide abstract]
ABSTRACT: The present research examined vision attentional processing of location and color cues information in three-dimensional (3-D) space using cuing paradigm by means of a three-dimensional attention measurement apparatus. Experiment used three cues information (valid, invalid and neutral), two color information (red and green), and three interstimulus intervals (ISIs) (200, 400 and 600 ms). Subjects were required to respond to cued spatial targets according to prior cue information which was highlighted in red or green in the fixation point. Target was highlighted in red or green in one of the target locations (nearer or further location). Results indicated that although there was no effect of color validity when location cues were valid, there was a significant effect of color validity when location cues were invalid, and there was significant main effect of ISI. Reaction time was longest in 200 ms ISI than that in 400 and 600 ms ISIs.Measuring Technology and Mechatronics Automation, International Conference on. 2:607-610.
