内隐变化觉察中的视觉表征特点
发布时间：2018-09-19 10:04
【摘要】：许多研究都证实了这样一种观点：视野内出现的客体或事件即使没有被有意识地觉察到,也能够影响行为。未被意识到却影响了后续判断行为的变化觉察即内隐变化觉察。本研究采用Fernandez-Duque和Thornton(2000)的内隐变化觉察范式,通过三个实验试图揭示前注意阶段或意识水平之下视觉特征的表征情况和分心物对目标任务的影响,以及游戏经验对个体在视觉表征、注意等方面的影响。 三个实验均以内隐变化觉察的正确率和反应时为因变量。实验一包括参与者类型(包括有游戏经验与无游戏经验2个水平)、基本特征(包括颜色和形状2个水平)和视野位置(包括副中央窝区和边缘视野区2个水平)三个自变量；实验二包括参与者类型、视野位置和特征变化维度(包括仅颜色变化、仅形状变化和两维度均变化3个水平)三个自变量；实验三包括参与者类型和有无分心物两个自变量。 实验得出以下结果：(1)研究参与者对客体颜色变化的内隐觉察率高于形状变化,对处于副中央窝区域内客体的内隐变化觉察率高于边缘视野区；(2)仅颜色变化与两维度变化的内隐觉察率无显著差异,且均高于仅形状变化；(3)分心物的出现使研究参与者的内隐变化觉察率有所下降,但有游戏经验的研究参与者觉察率下降不显著；(4)在三个实验中,有游戏经验的研究参与者的内隐变化觉察率均高于无游戏经验的研究参与者。 本研究得出以下结论：(1)颜色特征在前注意阶段的视觉表征中表现出了优势,能够更好地引导后续的变化判断行为；(2)游戏经验能使个体在更大的视野范围内具有更加丰富而完整的视觉表征,其中,颜色特征的丰富性更为明显；(3)颜色特征分心物干扰了内隐的变化觉察,但游戏经验能使个体更好地降低这种任务无关因素的干扰。
[Abstract]:Many studies have confirmed the view that objects or events in the field of vision can influence behavior even if they are not consciously perceived. Unawareness affects the perception of changes in subsequent judgment behavior, that is, implicit change awareness. Using the implicit change perception paradigm of Fernandez-Duque and Thornton (2000), this study attempts to reveal the representation of visual features under the level of pre-attention or consciousness, the effects of distractions on target tasks, and the visual representation of individuals by game experience through three experiments. The influence of attention, etc. The accuracy and response time of implicit change perception were all used as dependent variables in the three experiments. Experiment 1 included three independent variables: participant type (including two levels with and without experience), basic characteristics (including two levels of color and shape) and visual field position (including two levels of paracentric fossa and marginal visual field). Experiment two included three independent variables: participant type, visual field position and feature change dimension (including 3 levels of color change only, only shape change and change of both dimensions); experiment 3 included two independent variables: participant type and distraction. The results were as follows: (1) the implicit perception rate of the object color change was higher than that of the shape change, and the implicit perception rate of the object in the paracentric fossa was higher than that of the marginal visual field; (2) there was no significant difference in the implicit perception rate between the color change and the two dimensional changes, and both of them were higher than those of the only shape change, (3) the implicit change perception rate of the study participants was decreased by the appearance of distraction. However, the perceived rate of the participants with game experience was not significantly decreased; (4) in the three experiments, the implicit change awareness rate of the participants with game experience was higher than that of the study participants without game experience. The main conclusions of this study are as follows: (1) Color features show advantages in the visual representation of pre-attention stage and can better guide the subsequent change judgment behavior; (2) the game experience can make the individual have more abundant and complete visual representation in a larger visual field, among which, the richness of the color feature is more obvious, (3) the distraction of the color feature interferes with the implicit change perception. But the game experience can make the individual better reduce the interference of this kind of task independent factor.
