【摘要】：功能性视盲是指由于某种原因导致正常的视觉系统出现视觉觉察丧失的现象,例如变化知盲、注意瞬脱等都属于功能性视盲。情绪诱发的视盲指的是一个与任务无关的情绪性刺激的呈现吸引了注意以致个体无法对快速呈现的靶刺激有所觉察的现象。与注意瞬脱特别是情绪性注意瞬脱相比,情绪诱发的视盲是以情绪刺激为干扰刺激,考察情绪刺激如何以自下而上的方式吸引注意并干扰靶刺激的加工,因此有着自己的特点:它没有lag1节省现象,也没有像注意瞬脱那样严格的时间窗口限制,不受干扰刺激与靶刺激物理特征相似程度的限制,在心理机制上属于早期知觉阶段的加工竞争等等。情绪诱发的视盲表明情绪对注意在时间和空间两个维度上都有吸引或干扰作用。未来可以从考察神经机制、了解影响因素等多方面深化此领域的研究。
[Abstract]:Functional visual blindness refers to the loss of visual awareness in normal visual system due to some reason. For example, change blindness, attention blink and so on all belong to functional blindness. Emotional blindness refers to a phenomenon in which the presentation of a task-independent emotional stimulus attracts attention so that individuals are unable to perceive the rapid presentation of the target stimulus. Compared with attention blink, especially emotional attention blink, the visual blindness induced by emotion is based on emotional stimulation as interference stimulus. This paper investigates how emotional stimulation attracts attention and interferes with the processing of target stimulus in a bottom-up manner. So it has its own characteristics: it does not have lag1 savings, nor is it subject to the same strict time window constraints as attention to transients, not to the extent to which the physical characteristics of the interference stimuli are similar to those of the target stimuli. In the psychological mechanism belongs to the early perceptual stage of processing competition and so on. The visual blindness induced by emotion indicates that emotion can attract or interfere with attention in two dimensions: time and space. In the future, the research in this field can be deepened by examining the neural mechanism and understanding the influencing factors.
