自我参照表征能否影响环境参照表征:来自自我中心表征程度的证据

Can egocentric affect allocentric representation:Evidence from degree of egocentric representation studies

自我中心参照框架与环境中心参照框架之间存在着相互影响。但在二者的相互影响中,自我中心参照对环境中心参照表征影响是否稳定出现还存在一定的争议。为了考察自我中心参照对环境中心表征影响是否由于自我中心表征程度所决定,实验1中采用自我与环境中心参照冲突范式,分别在远处和近处空间条件下探究自我中心参照对环境中心参照表征的影响。结果发现,左侧视野中近处空间自我中心参照与环境中心参照冲突大于远处空间。鉴于刺激-反应兼容性能够影响被试的反应,实验2要求被试使用左手进行反应,目的在于考察自我中心参照对环境中心参照表征的影响表现出的视野差异是否是由于刺激-反应兼容性造成的。结果发现,右侧视野中近处空间自我中心参照与环境中心参照的冲突大于远处空间。研究表明,自我中心参照是否影响环境中心参照表征的一个重要因素为自我中心表征程度,并且自我中心表征程度的影响受到刺激-反应兼容性的影响。

Spatial reference frame refers to the way that individuals represent spatial orientation.Specifically,it can be divided into two types:Egocentric reference frame and allocentric reference frame.Using these two different spatial reference frames can better represent spatial orientation in different spatial positions.There was mutual influence between egocentric(EGO)reference frame and allocentric(ALLO)reference frame.However,in the interaction between the two,whether the influence of EGO reference on the representation of ALLO reference was stable was still controversial.In order to investigate whether the influence of EGO reference on ALLO representation was determined by the degree of EGO representation.In Experiment 1,the conflict paradigm of EGO reference and ALLO reference was used to explore the influence of EGO reference on the representation of ALLO reference in far and near spaces.The results showed that the conflict between EGO reference and ALLO reference in the near space was greater than that in the far space in the left visual field.Since the stimulus response compatibility(SRC)can affect the response of the participants.In Experiment 2,the participants were asked to use their left hand to respond.The purpose of Experiment 2 was to investigate whether the visual field difference caused by the influence of EGO reference on ALLO reference representation was caused by SRC.The results showed that the conflict between EGO reference and ALLO reference in near space was greater than that in far space.The results indicated that the degree of EGO representation was an important factor of whether EGO reference affects ALLO reference representation,and the influence of EGO representation was affected by SRC.
