    Abstract: Self-control refers to the mental processes that ensure people to overcome thoughts and emotions, thus enabling behavior to vary adaptively from one situation to another. While self-control plays an important role on individual’s well-being, the failure of self-control is one of the key problems of human society. Based on the sequential-task paradigm, researchers have explored the cognitive mechanisms of self-control failure and have proposed multiple theories such as the strength model, the process model, the central governor model and the prefrontal-subcortical balance model of self-regulation. In the field of neuroimaging studies, the researchers have identified the involvement of several brain regions, including inferior frontal gyrus, amygdala, orbitofrontal cortex, dorsolateral prefrontal cortex and nucleus accumbens. In the future, the researchers should emphasize the integration of different theories, strengthen the neural mechanisms associated with self-control failure, and explore the relationship between self-control failure and social behaviors.

    Abstract: Correlation heuristic is a mental model in which judgment bias in understanding accumulation is aroused when people correlate accumulations and flows and assume that the patterns of accumulations and flows are similar. Correlation heuristic bias, termed as “stock-flow failure”, can be found in understanding interactive dynamic systems. Due to lack of appreciation of the basic principles of accumulation, individuals tend to use this heuristic, where they intuitively assume that the pattern of stock highly correlates with the pattern of inflow or net flow. They attempted to match the stock’s trajectory along with the inflow rate. Research shows that correlation heuristic bias is common in decision making for simple as well as multi-faceted decision making tasks. The heuristic has significant implications in business management decision making and is not conducive for people’s sustainable decision-making. Results of research on the individual factors such as object bias, attribution substitution, and insufficient adjustment and contextual factors that may influence correlation heuristics are inconsistent. Empirical studies that explore factors impacting correlation heuristics have emerged. Effort to explore ways of reducing such bias has started. This article systematically reviewed the correlation heuristic literature and recommended areas to be further explored in future studies, including clarifying its inner mechanism, digging into potential influencing factors and their interactions, enhancing research paradigms, and developing methods that can reduce correlation heuristic.

    Abstract: Attentional bias towards threat information is a common phenomenon in Posttraumatic Stress Disorder (PTSD) individuals. A number of studies have investigated the processing characteristics and internal mechanisms of attentional bias by using eye-movement technology. it is found that factors influenced the three components are distinct. First, facilitated attention is the consequence by the interaction of the threat stimulus type and the eye movement indicators. PTSD individuals are more likely to be alert to threat words, which is not only related to the interference of pictures and words in the recognition process, but also affected by arousal, salience and complexity of stimulus. Furthermore, the smaller visual angle presented in previous studies may also accelerate the attentional capture of threat words. In addition, the inconsistent selection of eye movement measures may also cause the difference of the results of attention directed acceleration: the first fixation latency is not sensitive to the component due to the inability to measure the apparent eye movement. Moreover, the spatial indicators are more suitable to investigate this processing to threat words, but pupil index is more appropriate to threat pictures. Second, PTSD individuals do not have the difficulty in attention disengagement to threat words. It may be related to preview, information density, and unconscious binding. Words preview leads to rapid processing; however, it is not available to continuously capture the attention because of low information density. Besides, the unconscious binding of “static-words” also makes it difficult to show the difficulty in attention disengagement to threat words. Third, the absence of attentional avoidance to threat information may be a long-term self-protection strategy adopted by PTSD individuals, and this result will not be affected by analysis methods, stimuli types, and presentation time. Therefore, it is more likely to be the mechanism of “facilitated attention - difficulty in attention disengagement”. Indeed, compared with behavioral response time, eye tracking technology can monitor the time course of attention while PTSD individuals look at the threat stimuli. On the one hand, it can deeply understand the attention characteristics of PTSD individuals caused by different types of traumatic events, and on the other hand, it can verify relevant attention-biased stage theory. From the observation of phenomenon to the theoretical construction, it is a more comprehensive investigation of the attentional bias processing mechanism to this type of affective disorder. Future research may also should to pay attention to the following aspects. First of all, whether researchers can maximize the advantages of eye movement technology is still worth discussing. They can construct the unique attentional bias eye movement pattern and corresponding eye movement model of PTSD individuals from multiple dimensions based on the perspective of eye movement mechanism, for example, age. The PTSD rate of American children and adolescents is higher than that of American adults caused by the same experience, and compared with PTSD adults, PTSD children will show more hypervigilance and traumatic memories of repeated intrusions. In addition, the immaturity of the eye physiological system of children and adolescents may lead to more limitations or inconsistent eye movement patterns. The superposition of these differences may cause heterogeneity in the eye movement patterns of attentional bias between different PTSD groups. Consequently, it is necessary to construct corresponding attentional bias eye movement patterns and theoretical models from the age level for researchers. Second, when researchers make full use of eye tracking technology to investigate PTSD attention bias, they also need to combine multiple technologies to investigate the threat attention bias mechanism of PTSD individuals from a multimodal perspective, such as physiological indicators, event-related potentials, and so on.

    Abstract: Anchoring effect refers to the phenomenon that a target estimation was influenced by the numerical anchor value in the way that the final judgment would be close to the anchor value. Previous studies have found that external anchor could improve ones' attitudes and behaviors that may promote their physical and mental health. However, studies about other anchor types were not being found in the literature. Anchor values ??that are highly personally relevant can stimulate deep processing. The current study integrated anchor value with prevention science, conducted two on-site experiments that focused on the physical and mental health of older adults and adolescents, and explored design options of internal anchors and fine anchors and their effectiveness in improving outcomes. Experiment 1 examined the effect of positive nostalgia on the emotional state and well-being of older adults. A two-factor mixed design was adopted. A positive nostalgic internal anchor (the number of positive reminiscences) was built through 10-week nostalgic story sharing. 80 senior citizens participated in 10 weeks’ interventions of compelling narrative life sharing (positive nostalgia condition) and collecting life stories (free nostalgia condition). The subjects shared two stories per week about different topics. The first experiment tested whether the positive nostalgia of internal anchors had any effect on positive emotions and happiness. The results showed that, the number of pleasant and inspirational stories (positive internal anchor) in positive nostalgia group was significantly higher than those in the free nostalgia group. The positive mood and well-being of the positive nostalgia group (intervention group) were significantly higher than those of the free nostalgia group (control). Experiment 2 examined the influence of fine anchor on persistence of physical activity among middle school students. There were three study conditions: fine anchors, rough interval anchors and no anchors. According to their base line performance in plank and 2 minutes rope skipping, 180 adolescents were divided into 3 groups Individualized “motivation tips” were delivered before the second experiment. It was found that the self-reported persistence levels and improvement rates were higher among students in the fine anchor group than those of the other two groups. Results of comprehensive analysis showed that the designed internal anchors and fine anchors played an active role in promoting physical and mental health among older adults and adolescents. The study provided evidence that self-generating internal anchor or fine anchor for individual promotes positive attitudes and behaviors on physical and mental health. A possible mechanism of the effect could be that the anchor values were personally relevant and could stimulate deep processing, which in turn triggered changes in feelings, emotions, or motives. Results of the study have implications on practical significance for improving the physical and mental health of older adults and adolescents and for increasing ways and methods to improve their health.
