Abstract:
Objective:Two experiments were performed to research the effects of visual field factor on pseudoneglect and to test the theories about neglect and pseudoneglect.Methods:Experiment 1 employed the landmark task and greyscales task in tachistoscopic and forced-choice conditions.Experiment 2 employed the greyscales task and tachistoscopic visual three-field technique.Results:Experiment 1 manifested that greyscales had no crossover effect;the length factor had effect on the greyscales task as the landmark task,but it only affected the bias magnitude,not the error direction.Experiment 2 indicated that the main effect of visual field was significant:when the greyscales were presented in the middle or right,pseudoneglect manifested,but when in the left,pseudoneglect vanished.Conclusion:The results provide evidence supporting the hypothesis that the perceptual distortion derives from the attentional process.
