摘要
该研究采用多目标追踪任务(MOT)对追踪过程中被试的眼动进行记录,探讨追踪过程中的眼动模式及目标数量与刺激物大小变化对眼动模式的影响。结果表明,在追踪过程中,视觉系统采用知觉组织加工策略,以被追踪目标构成的多边形中心为注意中心;追踪成绩受到注意资源限制,随着目标数量的增加,每个目标获得的资源减少;获得较多注意资源的目标更容易被有效追踪,获得资源较少的目标更容易丢失;目标与非目标属性的共同变化不影响追踪眼动模式和追踪成绩。
To investigate the eye movements pattern during a multiple-object tracking（MOT） task,college students participated in this experiment,in which their eye movements were monitored.Results indicated that visual system adopted perceptual grouping strategy to fixate closer to the center of the polygon formed by the targets.The tracking performance was limited by the attention resource and gaze time on each target was decreased by the set-size.Moreover,we found that tracking accuracy increased with gaze time on targets,and decreased with gaze time on non-targets.The eye movement pattern and tracking performance were not influenced by the common feature change of targets and non-targets.
