3093.5 Exprimental studies on group difference of attentional blink, Yongrui Li, China
Attentional Blink is post-target stimuli processing deficit in RSVP when the subjects are asked to
detect the target stimulus. In this study, 353 students, 134 teble-tennis players and 67 soccer
players were tested. Results showed that each group involved had attentional blink and more or
less group difference among them. it could be inferred that (1) attentional blink could facilitate
human to understand its information-processing ability and its psychological essence;
(2)attentional blink should be broadly used in talent selection, pinpointing training and the
designing of complex instrument for the specific operators who received information mainly from
visual channel.
3093.6 Metacontrast masking effect on number processing in different attention conditions,
Chao Liu, Xiao lan Fu, Institute of Psychology, Chinese Academy of Sciences, China
We investigated metacontrast masking effect on number processing. Numbers in different
magnitudes and notations were presented in attended or unattended condition first; a black ring
presented in random SOA served as metacontrast mask. Detection task and comparison task were
used. The U shaped metacontrast masking function of different numbers was tested. The results
showed that: In attended condition, all the numbers showed no U shape function in both detection
task and comparison task; in unattended condition, all numbers showed clear U shape function in
detection task, but only small Arabic numbers showed distinct U shape function in comparison
task.
3093.7 Research on semantic interference in unconsciousness cognition of word-picture in
background context, Yun Tao, Jin-zhi Fu, Ji-liang Shen, China
This research examined words or pictures presented in isolation and scenes, studied objects
automatically activate their semantic representations. In experiment 1, the automatic activation of
words or objects will enhance the matched items or interfere in the unmatched ones. In experiment
2, the matched or unmatched items will interfere in the process without the identical items of
object. In experiment 3, When the same words and objects from the experiment 2 were inserted
into scenes in which those objects were matched or unmatched, interference occurs from matched
objects but not unmatched ones. Implications for models of object identification are discussed.
3093.8 The influence of fog on car following distance, Viola Cavallo 1 , Eymeric Beaudoin 2 ,

The hypothesis of distance misperception in fog has recently been corroborated by a series of fog
chamber studies (Cavallo et al., 2000), showing an overestimation of 30-60 % of vehicle distance
in foggy conditions, when the vehicle lights but not its outline remained visible. To validate these
findings in a more ecological setting, we studied the control of following distance in a driving
simulator experiment. Results revealed shorter following distances in all foggy conditions,
irrespective of the visibility of the vehicle outline. The interpretation of these findings refers to the
use of various distance cues and the constraints due to.
