Abstract：
Despite the unlimited capacity of sensory registration, visual system can still provide an efficient summary of a cluttered scene, representing the statistical properties of multiple objects rather than forming detailed representations of individual objects. There is growing interest in the behavioral study of statistical summary representations (SSRs), especially in the exploring of their automatic mechanism as well as the domain-general or domain specific ensemble mechanism. However, the neural underpinnings of SSRs have received far less attention. Future work on SSRs may use neuroimaging methods to investigate their neural substrates directly, which is also important for understanding neural computation.

Abstract： [Objective] To explore the influence of public health emergencies on the psychological state of the public, and understand its changing characteristics and rules. [Methods] We acquire active Weibo users from 2020/1/13 to 2020/2/26 at first, and extract features from these users’ data, including word frequency, negative (anxiety, depression and force), positive (life satisfaction and oxford happiness) and social attitudes (social risk judgment and anger) index. We then compare the differences of psychological characteristics between 2020/1/13-2020/1/19 and 2020/1/20-2020/1/26. [Results] The result indicates that the frequency of negative emotional words (t=-18.533, p < 0.05) and anxious words were increased (t=-17.433, p < 0.05), family words (t=7.907, p < 0.05) and friend words decreased (t=6.897, p < 0.05) after 20-th. Meanwhile, anxiety (t=-35.962, p < 0.05), depression (t=-10.717, p < 0.05) and obsessiveness (t=-24.755, p < 0.05) were increased. Oxford happiness (t=3.120, p < 0.05) and life satisfaction (t=5.500, p < 0.05) were decreased. The levels of social risk judgment (t=-8.832, p < 0.05) and anger (t=-11.415, p < 0.05) were increased. [Limitations] The weekly measurement of the data is considered as a relatively large scale, which has a certain influence on reflecting the trend of social mentality timely. [Conclusions] After the official confirmation and attention to the incident, the overall state of mind of the society showed an increase in negative emotions such as anxiety and anger, as well as a decrease in well-being and an increase in sensitivity to social risks.
