As we are cognizant of only a fraction of the available visual inputs at any given time, how is information selected for access to consciousness? In particular, does the personal significance of stimuli influence perceptual selection? Given that self-relevant information is prioritized during various stages of processing, here we hypothesized that self-association may privilege access to awareness under continuous flash suppression (CFS). The results supported this prediction. Compared with geometric shapes referenced to either a friend or stranger, those previously associated with self were prioritized in visual awareness. To establish the basis of this effect, the processes underlying task performance were investigated using a hierarchical drift diffusion model approach. These analyses showed that self-prioritization mapped onto both the decisional (i.e., starting value, ) and nondecisional (i.e., ₀) parameters of the diffusion model. The implications of these findings are considered. (PsycINFO Database Record
由于在任何给定时间我们只能感知到一小部分可用的视觉输入,那么信息是如何被选择以进入意识的呢?特别是,刺激的个人意义会影响知觉选择吗?鉴于与自我相关的信息在处理的各个阶段都被优先处理,我们在此假设,在持续闪光抑制(CFS)下,自我关联可能会优先进入意识。结果支持了这一预测。与参照朋友或陌生人的几何形状相比,那些先前与自我相关联的形状在视觉意识中被优先处理。为了确定这种效应的基础,我们使用分层漂移扩散模型方法研究了任务表现背后的过程。这些分析表明,自我优先处理映射到扩散模型的决策参数(即起始值)和非决策参数(即₀)上。我们考虑了这些发现的意义。(PsycINFO数据库记录)
