Abstract： In recent years, with the growing popularity of internet-based devices, children are increasing exposed to various applications, especially video chat. Researchers begin to explore the potential influence of video chat on children's development. It was found that compared with traditional communication technology, video chat had the feature of audio-visual combination and real-time interaction. However, video chat still maintains the two-dimensional feature as traditional screen media. By summarizing current research focused on video chat and children's learning, it is found that compared with yoked video learning, video chat had a positive effect on children's vocabulary learning (d = 0.33) and movement learning (d = 0.90). Moreover, video chat helped children to maintain a high level of attention in the learning process (d = 0.90). Compared with traditional video learning, the advantage of video chat learning lies in that it can provide children with two different kinds of social cues: the relevance feedback provided by on-screen teachers and other social cues provided by the co-viewer in the scene, which can effectively improve the occurrence of video deficit to a certain extent and help children transfer the knowledge learned on the screen to the real world. At present, researches on video chat and children’s social development mainly focuses on the long-distance parent-child relationship and peer relationship. It is found that video chat has the potential to maintain or form secure attachment for children who are experiencing parent-child separation, and can promote the long-distance parent-child relationship to some extent. Meanwhile, studies found children can successfully carry out a series of free games with a long-distance partner through video chat. The remote interactive environment of mutual gaze created by video chat can also improve the sense of presence and mutual understanding between children and their partners in remote games. In addition to helping normal children with learning and social development, video chat can be used as an adjunctive therapy for intervention of children with disorders (e.g., ASD, Obesity), to help them improve their health and social skills. Future research might focus on expanding the age range of children in video chat learning, the influence of children’s previous experience with media and the different supportive behaviors of co-viewers on children’s video chat learning. Future research should also further explore the impact of video chat on children’s social development under the condition of long-term separation. And whether children’s video chats with other family members can help strengthen family bonds and encourage distant family members to become more involved in each other's lives, thus promoting children’s development.

Abstract： Previous empirical research has found the effect of insight on promoting memory retention during problem solving. Furthermore, neuroimaging studies have revealed that the amygdala, which is assumed to be associated with Aha experience, plays an important role in long-term memory of insightful events. While the emotional Aha experience is a key characteristic of insightful problem solving, some researchers emphasized that the core processes in creating insights involve breaking the mental set and forming novel and valuable associations. However, the cognitive and neural mechanisms underlying the promoting effect of insight on memory have not yet been fully explored. In this study, the paradigm of choice of answers to ChineseChengyu riddles was adopted to investigate how the process of forming novel associations impacts the effect of insight on promoting subsequent memory. Two experiments were conducted in this study. In Experiment 1, the paradigm of choice of answers to ChineseChengyu riddles consisted of two phases. In the learning phase, participants were asked to select the novel and suitable answer to theChengyu riddle from four options; after one week, in the testing phase they were asked to recall the answer that they chose in the learning phase. The novel association and normal association condition were distinguished according to the selections of participants. The paradigm used in Experiment 2 was similar to that of Experiment 1. Additionally, the functional Magnetic Resonance Imaging (fMRI) was used to record the neural activity in the learning phase. The results of Experiment 1 showed that the score of Aha experience in the learning phase and accuracy in the testing phase were significantly higher in the novel association condition compared to the normal association condition. In addition, Experiment 2 showed that the activity in the brain regions related to insight, including the hippocampus, amygdala, middle frontal gyrus, superior temporal gyrus and middle temporal gyrus, were significantly greater in the successful recall compared to the failed recall in novel association condition. Further analysis indicated that successful recall of novel association involved more activity in the right hippocampus compared to the recall of normal association. The current study verified the promoting effect of insight on memory, and indicated that forming novel semantic associations and related activity in the hippocampus may underlie this effect.
