摘要：
<jats:title>Abstract</jats:title><jats:p>The present study examined whether individuals experienced the same cognitive advantage for online self-relevant information (nickname) as that experienced for information encountered in real life (real name) through two experiments at both the behavioural and neural levels (event-related potential, ERP). The results indicated that individuals showed the same cognitive advantage for nicknames and real names. At the behavioural level, a nickname was detected as quickly as the real name, and both were detected faster than a famous name; at the neural level, the P300 potential elicited by one’s nickname was similar to that elicited by one’s real name, and both the P300 amplitudes and latencies were larger and more prolonged than those elicited by other name stimuli. These results not only confirmed the cognitive advantage for one’s own nickname and indicated that this self-advantage can be extended to online information, but also indicated that the virtual self could be integrated into the self and further expanded individuals’ self-concept.</jats:p>

摘要：
Interpersonal sexual objectification experiences are pervasive in online communication contexts, and their influence on positive eating behaviors should not be ignored. Broad conceptualization of beauty refers to how widely women and girls define female beauty in terms of both internal and external characteristics, and body appreciation refers to loving, respecting, and holding a positive attitude toward the body. This study examined the association between online interpersonal sexual objectification (OISO) experiences and intuitive eating, as well as the mediating role of broad conceptualization of beauty and body appreciation. Participants were 1152 Chinese adolescent girls aged 11 to 15years who completed a questionnaire survey measuring OISO experiences, broad conceptualization of beauty, body appreciation, and intuitive eating. The results showed a negative association of OISO experiences with broad conceptualization of beauty and intuitive eating. Mediation analysis using structural equation modeling showed a negative association of OISO experiences with intuitive eating through broad conceptualization of beauty and body appreciation. These results suggest that programs aiming to improve healthy eating behaviors could direct adolescent girls to criticize the appearance-focused mindset in online interaction and encourage them to focus on body functionality, such as health, creative endeavors, and communication with others.
摘要：
Previous studies have documented that mindfulness was positively correlated with favorable sleep quality, however, the underlying mechanisms are largely unknown. The present study examined the mediating role of rumination and the moderating role of self-control in the association between mindfulness and sleep quality. A sample of 1196 adolescents completed a battery of self-report questionnaires measuring mindfulness, rumination, self-control and sleep quality as well as demographic information. Results showed that, in addition to the negative link between mindfulness and poor sleep quality, mindfulness was negatively associated with rumination, which in turn was positively associated with poor sleep quality. The direct link between mindfulness and poor sleep quality and the indirect link through rumination were both moderated by self-control. These two effects were stronger for adolescents with low self-control than for those with high self-control. These results coincide with the antagonistic interaction hypothesis of the protective-protective model, and indicate that mindfulness and self-control, as two important protective factors of adolescents, may mutually compensate. Limitations and implications are discussed.

摘要：
The present study aimed to examine whether a self-related stimulus produces a self-related process bias between pathological-tendency Internet users and ordinary Internet users. Participants were asked to judge the color of the target stimulus' frame (Internet pictures) in an implicit priming task, which enclosed the prime of self/other related words and the target of the online image in sequence. Results from Experiment 1 showed that response time (RT) in the self-related condition was significantly longer than that of the other related condition. Further analysis showed that RT in the self-related condition was significantly longer than that under the other related conditions for pathological-tendency Internet users but not for ordinary Internet users. In Experiment 2, behavior results demonstrated that RT under the self-related condition was significantly longer than that in the other-related condition for both groups, and the RT was shorter for pathological-tendency Internet users than that of the ordinary Internet users. Moreover, ERP data showed that the N2 amplitude was larger in the self-related condition than that of other related conditions for pathological-tendency Internet users but not for ordinary Internet users. The amplitudes of late positive component (LPC) was smaller in the self-related condition than those of the other related conditions. Hence, the Internet use influenced the inhibition control in self-unrelated stimuli and automatically retrieved the self-related stimuli.
摘要：
Restrained eating for weight control and loss is becoming highly prevalent in many affluent societies, while most of the restrained eaters are rather unsuccessful in the long term. According to the strength model of self-control, the disinhibition effect of restrained eaters may occur after the depletion of self-control resources. However, no work has examined the direct impact of self-control resources on inhibitory control ability of restrained eaters. This study investigated the influences of self-control resources on the food-related inhibitory control among high-restraint/low-disinhibition restrained eaters, high-restraint/high-disinhibition restrained eaters and unrestrained eaters using stop signal task. Results reveal that there's no difference of food-related inhibitory control between three groups when the self-control resources are non-depleted, while high-restraint/high-disinhibition restrained eaters showing a decrease of food-related inhibitory control after ego-depletion. This disinhibition effect only seems to occur in samples of restrained eaters with a high tendency toward overeating. (C) 2017 Elsevier Ltd. All rights reserved.
