Other Abstract

We were born in relatively peaceful times, but we are still constantly exposed to threatening situations and threatening stimuli. For human beings, threats in life mainly come from social environment, and one of the ways to convey such threats is the faces of others. Therefore, this study investigated the processing mechanism of immediate and potential threat faces by controlling threat situations. From the three aspects of face subjective judgment, attention and recognition, the processing of threat faces conforms to the single-system theory or the dual-system theory.

In this thesis, I first summarized the single- and dual-system theories of threat and summarized the empirical evidence for immediate and potential threat stimuli and situations. On the basis of previous studies, in view of the lack of direct comparison of immediate potential threat systems and the role of context in the face research, I proposed my research scheme to verify the theory of single system and dual system. In experiment 1, the influence of the situation on the subjective judgment and recognition of the threatening face was carried out. In experiment 2, the influence of the situation and the threatening face on the task interference was carried out. In experiment 3, the eye movement equipment was used to explore the mechanism of the recognition advantage or disadvantage of the threatening face. The results showed that the threat situation did not play a significant role, but the processing of threat faces conforms to the dual-system theory. The immediate threat faces have the advantage of attention capture and memory, while the potential threat faces show the alertness and attentional avoidance and have the difficulty of memory. Although the eye movement could not reflect the alert of immediate threat faces, this result may reflect the high processing efficiency of immediate threat faces to some extent.

By integrating subjective evaluation, behavioral and eye movement studies, the current study draws a relatively consistent conclusion from the perspective of comparison between immediate threat and potential threat: there are differences between immediate threat and potential threat in subjective evaluation and recognition, which provides empirical evidence for the dual-system theory of threat. The processing difference between immediate and potential threat faces may be due to the top-down intention judgment of intentional or unintentional threat in the cognitive process, as well as the important role of bottom-up attentional features.
