Abstract:

Pseudoneglect is “healthy subjects tend to exhibit a subtle bias of visual attention favouring left space”. There are many factors that affect pseudoneglect, such as stimulus, age, cognitive load and perceptual load. Among them, eye movement habit has been coded as the major factor to the explanation of pseudoneglect. However, recent neural studies exhibited that right hemisphere VAN contributed to pseudonegelct more than left hemisphere. The right hemisphere SLFⅡcorresponded to greater deviation to the left-hemi field than the other two SLF did. Moreover, pseudoneglect is occurred at time of 100~200 ms after stimulus displayed. While the duration time of visual searching is 1500 millisecond reaching to the greater left deviation. The application of current study is applied in the traffic driving to explore the relationship between drivers’ attention trait and driving visual search. The results indicated that two principles of safety transportation might be recognized. First, the safety driving setting should be consistent with the drivers attention trait. Second, it is necessary to cultivate safety driving visual search model by the mean of inhibiting visual search habit through the theoretical visual intervention.

Key words: pseudoneglect, attentional bias, neural mechanism, transportation safety
