markings depends on their placement. Research from laboratory and road environments shows
that optimal visibility is achieved through the perceptual phenomenon, “biological motion” which
is created by marking the limb joints. This configuration allows drivers to recognize pedestrians at
a long distance, whereas markings on the torso often are not perceived.
5028.155 Color preference of the computer screen of Chinese youth, Yan Ge, Kan Zhang,
Ronggang Zhou, Xi Liu, Institute of Psychology, Chinese Academy of Sciences, China
Three experiments, applying forced choice and subjective estimates, were designed to investigate
the color preference of the computer screen of Chinese young subjects. Both the background color
and foreground color, as well as their combinations were examined. The results showed that: 1,
Blue, purple, gray-blue and cyan were the more popular colors among the 8 colors for the
background color. 2, The foreground color preference was influenced by the background color, but
white, yellow series and green series were all popular foreground colors for the background color
of blue, purple and gray-blue. Some mechanism and implications were discussed.
5028.156 Computer anxiety and the relationship between computer anxiety and performance on
information processing tasks in undergraduate students, Junqing Wen, Han Buxin, Institute of
Psychology, Chinese Academic of Science, China
Computer anxiety (CA) of Chinese undergraduate students and the relationship between CA and
performance of computer-based information processing tasks were investigated in this study. Four
CA Scales and three experiments with computer trouble settings were administered. Results
showed that: (1) 16.50-17.92% students are in high-level of CA, (2) high level of CA was
significantly correlated with students of poor computer experience, from rural areas and have no
personal computers, (3) for the tasks, performances were influenced by both CA and state anxiety
jointly. Students with high-level of CA experienced more state anxiety during tests than those with
low-level of CA.
5028.157 Application of multiple resources theory in pilot selection, Kan Zhang, Xianghong
Sun, Yanfang Liu, Qunhui Yang, Ronggang Zhou, Institute of Psychology, Chinese Academy of
Sciences, China
Principle of the Multiple Resources Theory of Attention was implied to design a PC based pilot
selection device to test candidates cognitive capacities, with a tracking task as the first task, a
balancing task as secondary task, and 6 third tasks. It was found that only performance with three
tasks simultaneously may predict candidates' cognitive abilities of being pilots. Based on data
collected from more than 400 subjects, weights of the performance of combinations of the tasks as
parameters of a formula were decided.

In 3D space, participants were required to pay attention to a plane of a specific color, neglect
another, then react to the orientation of target plane. Compared with the results in the baseline
condition, reaction time was 72ms longer when its location was the same as the attended plane,
only 49ms longer when same as the unattended plane. EEG analysis revealed unattended plane
