    Abstract: Affect spin reflects the time-fluctuation characteristics of the individual. As non-cognitive personality that measures the intraindividual variability of core affect, affect spin is important for us to understand the individual difference in affect intravariability over time and its mental functions. Relative to affect flux, affect pulse, and other affect variability indicators within the individual, the main advantage of affect spin is that it constructs the position change trajectory in core affect space by using the method independent of reference dimension and experience intensity. And it focuses on temporal characteristics of the naturally occurring core affect state, rather than relies on a certain type of core affect dimension characteristics to explain affect variability. For the measurement, experience sampling method and day reconstruction method are generally adopted, and individuals assess their affect state in the present situation (or recall it) by constructing Affect Grid or performing adjective rating. The acquisition process and conversion method are relatively complicated in that people need to repeatedly track their daily core affect state, and affect spin can be representative as cross-time standard deviation of the vector angle of individual core affect space position within the evaluation period. Affect spin is thought to play a central role in the mental health such that having stable affect would strengthen people’s sense of security and control, thereby enhancing the level of adjustment of their mental health. Instead, when people always change their affects, it is difficult for them to anticipate their lives, and might generate self-conflict. As a result, they may lower their expectations for the future, and furthermore weaken mental health. Based on Affective Events Theory and Dynamics Model of Affect, we suggest that the experience of negative-inducing events and its assessments lead to the individual affect spin, and psychological adjustment, psychological disorders, problem behaviors, etc. are the consequences of affect spin. However, some qualities of mental health, such as interpersonal relationship, are difficult to determine whether it is the cause or the result of affect spin. It is more likely that there is a bidirectional relationship between them. In short, the occurrence and development of affect spin reflect the nature of the process of affect’s temporal dynamic variability on individuals’ physical and mental health, that is, the most fundamental reason that affect spin influences mental health lies in the affect destruction caused by negative events in life. However, the current empirical research about the effect of affect spin on mental health is still very limited. In the future, it is highly suggested to explore the process mechanism of affect spin on mental health. Attention should also be paid to investigate the joint mechanism of affect variability and its stability indicators on mental health function. At the same time, it should be strengthened to examine the influencing process of state affect spin on the individual’s mental health function, especially the dynamic relationship mechanism with the stability of interpersonal relationship.

    Abstract: Attentional capture refers to the phenomenon that task-related stimuli unconsciously capture attention and get priority processing in attentional orientation. Attentional control Settings (ACS) can guide attention to task-related stimuli, and then preferentially process it. When target is defined as a category composed of multiple objects, the attention system will form category-specific attentional control settings (cACS). Investigating the mechanism of cACS in attentional capture can not only expand and enrich previous theoretical research, but also provide basis and guidance for real life. The present study reviewed the characteristics of cACS. Firstly, related to the processing stage of cACS, some previous studies claimed it occurred at an early stage, while others thought it happened at a late stage. Two-stage hypothesis combined these two views and postulated that different cACS can guide attention independently at the early stage, and then integrate into one single cACS at the late stage. In addition, cACS can also be preactivated in the preattentive stage to improve the subsequent search efficiently. Secondly, relative to the processing weight of cACS, the attributes (e.g., color, size, shape or motion) of category, the size of items in category and the abstraction of categorical hierarchy were proven to be the impact factors of the processing weight of cACS. Specifically, the processing weight of cACS was lower than the feature-specific attentional control settings (fACS). The weight of color-specific cACS was larger than that of other cACSs. The weight of cACS was reduced along with a larger size of items in category. And the weight of superordinate-level cACS was lower than that of subordinate-level cACS. Thirdly, relative to the involved brain regions of cACS, we summarized the previous functional brain imaging research and found object-selective cortex (OSC) involved the processing of extracting cACS stored in long-term memory and selecting target/inhibiting distractor. Finally, we summarized the neural mechanisms of cACS in attentional capture. Firstly, cACS can preactivate in the early preattentive stage of processing to promote the detection of categorical stimuli (as the involvement of OSC). When the visual stimulus is occurred, cACS can compare the current stimulus to the definition of target (as the index of N1 and P1 components), the frontal parietal network (PFC, LIP, etc.) involve in the category judgment process, and the left superior temporal sulcus (lSTS) participate in the integration of top-down and bottom-up processing. The stimulus that matches target definition can induce attentional capture (as the index of N2pc component), while the stimulus that mismatches the target definition can elicit attentional inhibition (as the index of PD component). When cACS engage in visual search task, the processing weight of attention is affected by different attributes (color, shape, etc.), item size within category, category hierarchy. In addition, if the target is defined as multiple cACS (e.g., a digit with warm color), the different dimensions of cACS (e.g., symbol and color ) will affect attentional capture independently at the early stage, and then these two independent cACS can be integrated into one cACS in the late stage. In the late stage, the consolidation in working memory (as the index of CDA component) and the behavioral response (as the index of accuracy and response time and the involvement of SMA and precuneus) are involved. Future studies can focus on the categorical rejection template for distractors, the various effects of different types of cACS in attentional capture, and the mechanism of artificial cACS.
