Abstract： The babyface effect plays an important role in human social cognitive responses to others. It has been shown that the babyface effect coexists with gender, context, and other factors in trait inferences, and together they influence people's perceptions of and interactions with others. In addition, the eyeTUNE framework proposes the key hypothesis that the moderating role of social factors on gaze cueing effects (GCE) further depends on contextual factors. However, as an important information in social interactions, whether and how babyface co-influence social attention with other factors needs to be further explored. Based on the existing studies, we have two experimental hypotheses. First, we hypothesized that female with babyfaces and male with mature faces would elicit greater GCE. Second, we hypothesized that, consistent with the eyeTUNE framework, the babyface effect disappears or diminishes in a non-comparative context.
In the current study, we used attentional cueing paradigm to examine the specific manifestations of the babyface effect in social attention by manipulating different contextual factors. Experiment 1 presented the various types of stimuli in the same block in a comparative context, using a 2 (participant gender: male, female) × 2 (face gender: male, female) × 2 (face type: babyface, mature face) × 2 (gaze cue validity: valid, invalid) mixed experimental design (with participant gender as a between-participants variable) to explore how face type interacts with gender to affect social attention. To investigate whether babyfaces would still have an effect on the GCE when there was no comparative context between babyface and mature face. Experiment 2 presented the four conditions (female babyface, female mature face, male babyface, and male mature face) in a separate block.
The results of Experiment 1 (comparative context) found that gaze cueing effects were moderated by face type and face gender. Specifically, a larger gaze cueing effect was discovered when the cue appeared on the babyfaces compared to the mature faces under female face condition; whereas under male face condition, babyfaces induced smaller gaze cueing effects than mature faces. However, in Experiment 2 (non-comparative context), the pattern of results differed from Experiment 1 in that the gaze cueing effect was no longer moderated by the role of or interaction between face type and face gender, but only by participant gender. A combined comparison of the data from Experiments 1 and 2 revealed statistically significant differences between the patterns under the two contextual factors.
In summary, the present study extends the existing literature in several ways. First, it explores for the first time the role of babyface in GCE under different facial gender. Second, it also reveals the moderating role of contextual factor in individuals' social attentional processing with babyface. The above results illustrate that although male and female babyfaces can cause attentional bias in social interaction, it only exists in the comparative context with mature faces, but not in the non-comparative context. The results of this study further support the theoretical view of the eyeTUNE framework that the social modulation of the gaze cueing effect critically dependents on situational factors.

Abstract： As a critical positive psychological construct, gratitude is crucial for health and well-being. Previous studies have shown a significant positive correlation between gratitude and social well-being. Although it is proven that gratitude causes higher social well-being, little research has explored the effect of social well-being on gratitude. Based on the personal and social relationships model and self-determination theory, our research proposed that social well-being is an antecedent to gratitude. Thus, in this study, we aimed to examine the longitudinal relationship between gratitude and social well-being. The hypotheses are as follows: 1) Gratitude has a direct effect on social well-being; 2) Social well-being has a direct effect on gratitude; or 3) Gratitude and social well-being have reciprocal effects on each other. Two studies were designed to test the hypotheses. Study 1 adopted a two-wave cross-lagged design to explore the relationship between trait gratitude and social well-being. A sample of 563 undergraduate students was enrolled online and volunteered to participate in this research. According to the purpose of this study, participants were asked to fill in the gratitude and social well-being scales and to fill in the two scales again after a 7-month interval. The cross-lagged path analysis suggested the reciprocal effects between trait gratitude and social well-being. To reduce common method bias, we adopted a daily diary method in study 2. And in this study, 274 young adults completed daily gratitude and social well-being measures once a day for 21 consecutive days. Study 1 showed that trait gratitude at T1 significantly positively predicted social well-being at T2, while social well-being at T1 also significantly predicted trait gratitude at T2 over a long period. After controlling for age and gender, these effects remained significant. Consistent with study 1, study 2 indicated that state gratitude on the previous day could positively predict social well-being (γ = 0.09, SE = 0.03, t = 2.90, p = 0.004) on the next day. Social well-being on the previous day could also positively predict state gratitude (γ = 0.03, SE = 0.01, t = 2.84, p = 0.005) on the next day. Moreover, these relationships were stable after controlling for dates. In conclusion, the result supports the hypotheses. These observations show reciprocal predictive effects between gratitude and social well-being from the longitudinal research and daily diary method. In summary, gratitude is a significant antecedent variable in promoting individual social well-being. Thus, social well-being can be enhanced by gratitude interventions or gratitude education programs. In addition, social well-being also reinforces gratitude, which develops an upward spiral model. The findings of this study further expand the research on the relationship between gratitude and social well-being and provide a new way to improve personal social well-being.

Abstract： The positive psychological construct of gratitude is crucial for health and well-being. Previous studies have shown a significant positive correlation between gratitude and social well-being. However, no studies have examined this potentially reciprocal relationship from a longitudinal perspective. According to the broaden-and-build theory and gratitude amplification theory, we hypothesized that gratitude has a direct effect on social well-being. In addition, based on the personality and social relationships model and self-determination theory, we proposed that social well-being is an antecedent to gratitude. In summary, this research combines a longitudinal study and a daily diary investigation to systematically explore the causal mechanism between gratitude and social well-being. Study 1 employs a two-wave cross-lagged design to explore the long-term relationship between trait gratitude and social well-being. The sample comprised 563 undergraduate students, who all participated online. Pursuant to the study purpose, participants were asked to complete the gratitude and social well-being scales twice, separated by a seven-month interval. The cross-lagged path analysis suggested reciprocal effects between trait gratitude and social well-being. To reduce recall bias and explore the short-term association between gratitude and social well-being, Study 2 employs a daily diary method. A total of 274 young adults completed daily gratitude and social well-being measures for 21 consecutive days. In Study 1, trait gratitude at T1 significantly positively predicted social well-being at T2, while social well-being at T1 also significantly predicted trait gratitude at T2. These effects remained significant after controlling for age and gender. Consistent with Study 1, Study 2 also revealed a reciprocal relationship: state gratitude on one day positively predicted social well-being the next day, while social well-being on one day also positively predicted state gratitude the next day. Moreover, these relationships were stable after controlling for time trend. Overall, the results of Study 1 and Study 2 support the hypotheses by showing reciprocal predictive effects between gratitude and social well-being. In summary, we predicted that experiencing gratitude would lead to higher social well-being, which would, in turn, result in higher gratitude, activating an upward spiral. This work deepens understanding of the interaction between gratitude and social well-being, paving the way for future intervention research to help increase both.

Abstract：
Eye contact plays an important role in social interaction and can capture and hold attention. Previous studies have shown that eye contact can guide attentional allocation. However, a face with direct or averted gaze is a special object containing social information. The object’s guidance for attentional allocation is called object-based attention, in which items in the cued object are processed more preferentially than items in the un-cued object. It is still unclear how eye contact interacts with objects in guiding attentional allocation. Therefore, the aim of the present study was to investigate the impact of eye contact and the cognitive mechanism of object-based attention.
We conducted three experiments using the two-rectangle paradigm and objects with different gaze directions. In Experiment 1, faces were used as stimulus and to investigate whether and how eye contact interacted with face to guide attentional allocation. At the beginning of each trial, the fixation cross and two objects originally were displayed for 1000 ms on a screen. Then, a cue appeared randomly at any of the four ends of the two objects for 100 ms. After 0, 200, or 500 ms of inter-stimulus, the target appeared until the participant pressed the “M” key or remained on screen for 1,500 ms. A black screen was then presented for 500 ms after each trial. During the experiment, the participants were asked to locate targets by pressing “M” as quickly as possible. We ruled out the influence of low-level features by using contrast reversed faces in Experiment 2. In Experiment 3, cups overlaid with eyes were used to explore whether the effect of eye contact still existed on real objects.
The results of Experiment 1 revealed that there was a significant interaction between gaze directions, cue position, and stimulus onset asynchrony (SOA). Specifically, a larger object-based effect was discovered when the cue appeared on the direct-gaze face compared to the averted-gaze face under 300-ms SOA; however, there was no significant difference between them under 100- and 600-ms SOA. Further analysis showed that the differences in object-based effect occurred because the participants reacted more quickly to the target in direct gaze than in averted gaze under the invalid same-object condition, which indicated that direct gaze could capture attention and cause a larger object-based effect. The difference in object-based effect between direct and averted gaze at 300-ms SOA disappeared in Experiment 2. The results of Experiment 3 replicated the results of Experiment 1 and further demonstrated that the influence of eye contact on object-based attention can extend to real objects.
In conclusion, the present study extends the extant literature in several dimensions. First, it provides the first evidence, to the best of our knowledge, that eye contact interacts with objects, including faces and cups, in guiding attentional allocation. The top-down processing of eye contact facilitates the processing of objects under an invalid same-object location, which leads to greater object-based attention and supports the enhancement spreading theory. Second, it also reveals that the influence of eye contact on object-based attention is regulated by SOA.

Abstract： In order to improve the efficiency of IPv6 routing lookup, this paper put forward an IPv6 routing lookup algorithm (BTBF) based on the combination of B-Tree and Bloom filter for the uneven distribution of IPv6 routing prefix. BTBF includes two parts, namely, B-Tree and Bloom Filter lookup: firstly, this paper looked up the first 16bit value of routing prefix with B-tree, and linked the next step to Bloom filter through the mapping of middle bit vector of B-tree node; then, extracted the Next hop through the value mapping of Bloom filter bit array. The experimental results show that, compared with other Tree and Bloom filter algorithms, BTBF algorithm can effectively reduce space and time, and maintain stable routing performance under the condition of larger changes in Routing-Table Entries.
