摘要
自我相关刺激的加工优势体现于多种心理加工过程,然而自我相关刺激是否具有意识通达的优先性,还需对以往研究进行系统梳理.采用降级刺激强度、视觉掩蔽、双眼竞争、连续闪烁抑制、非注意盲、注意瞬脱作为意识阻碍的实验方法,同时将睡眠、麻醉与严重意识障碍条件作为研究手段,考查自我相关刺激在以上范式和条件中是否具有意识通达优势.部分研究发现了自我信息具有意识通达优先性的证据,并提出了诸多不同甚至冲突的假设,如:注意瞬脱和非注意盲通过中断注意过程阻碍视觉意识,那么是注意早期选择理论还是晚期选择理论能够更准确地解释自我相关刺激在两种范式中的加工优势.因此,未来需要进一步研究不一致的现象,探讨其背后的神经机制.
Abstract
The self-prioritization effects have been well-documented in many cognitive processing,yet the question wheth-er it also shows in conscious access remains contentious.To address this issue,researchers have employed a range of experimental paradigms including stimulus degradation,visual masking,binocular rivalry,continuous flash suppression,inattentional blindness,and attentional blink.Additionally,the altered consciousness states(sleep,anesthesia,and disorders of consciousness)have been employed in other studies.Some studies have found evidence of a self-advantage in conscious access,leading to the proposal of nu-merous conflicting assumptions.For example,attentional blink and inattentional blindness are hypothesized to disrupt visual con-sciousness by interrupting the attentional process.Consequently,a question arises regarding whether the early selection theory or the late selection theory can more accurately explain the processing advantage of self-related stimuli within these two paradigms.However,the debates remain unresolved,calling for future research to further explore the observed inconsistencies and the underly-ing neural mechanisms.
