Parents’ application of mediated learning principles as predictors of toddler social initiations

How parents support social learning at the preverbal level for toddlers with autism is rarely reported, limiting the field’s understanding of factors that may influence early development of social competency. As a central challenge in autism that is resistant to intervention, preverbal social initiating is an important indicator of social motivation. This study explored parents’ application of mediated learning principles. Mediated learning theory is based on active engagement in the learning process or “learning to learn” and the Joint Attention Mediated Learning intervention applied the principles to child and parent learning. The investigation explored associations between parents’ application of mediated learning principles with unprompted initiation of joint attention for 119 toddlers with autism. Postintervention videos of unstructured parent–child interaction were used to analyze parents’ application of the principles and child initiation of joint attention. Significant differences were found between intervention and control conditions in parents’ mediation of child learning. In a multiple regression analysis of associations between parents’ application of the principles and toddler initiation of joint attention, parents’ success in applying mediated learning principles predicted toddlers’ initiation of joint attention gains. Considered individually, the strongest predictor of initiation of joint attention was the principle Giving Meaning with the principle Encouraging also showing significance. Lay abstract Little is known about what parents can do to promote initiating joint attention for their toddlers with autism. Initiating joint attention is important because it is an indicator of social motivation and is associated with later communication ability. In this study, parents applied mediated learning principles to help their toddlers engage with them socially. The principles included helping their child focus on social interaction, giving meaning to the social elements of interaction (and de-emphasizing nonsocial elements), and helping their toddlers understand their own social ability by encouraging. At the end of the intervention period, we compared two groups. One group received the Joint Attention Mediated Learning intervention and the other received community-based early intervention services. We found that the Joint Attention Mediated Learning participants applied mediated learning principles more often than the other group. Then, we explored how parents’ application of mediated learning principles related to toddler initiating joint attention and found that parents who were successful in applying the principles had toddlers who were more likely to show initiating joint attention. Our findings indicate that the mediated learning process shows promise as a way to promote early social learning, although other elements of the Joint Attention Mediated Learning intervention, such as actively engaging parents in the learning process, may have also contributed to both child and parent learning.

Is left-behind a real reason for children’s social cognition deficit? An fNIRS study on the effect of social interaction on left-behind preschooler’s prefrontal activation

The left-behind phenomenon, caused by parent out-migration, has become a common social issue and might lead to long-term and potential risks for children in rural areas of China. It is important to investigate the effect of social interaction on prefrontal activation of left-behind children in China because of possible effects of parent out-migration on children’s social cognition. We recruited 81 rural Chinese preschoolers aged 52–76 months (mean = 64.98 ± 6.321 months) preschoolers with three different statuses of parental out-migration (including non-, partially, and completely left-behind children). Using functional Near-Infrared Spectroscopy (fNIRS), we compared behavior and brain activation and in three groups (non-, partially-, completely-left-behind children) under two different social interaction conditions (child-teacher and child-stranger situation). Results revealed that initiating joint attention (IJA) may evoke higher brain activation than responding to joint attention (RJA) in the prefrontal cortex (PFC), especially in the case of initiating joint attention with the stranger. In addition, the activation of joint attention was positively correlated with children’s language score, cognitive flexibility, and facial expression recognition. More importantly, partially-left-behind children evoked higher brain activation in the IJA condition and presented a higher language level than completely/non-left-behind children. The current study provides insight into the neural basis of left-behind children’s development and revealed for the first time that family economic level and left-behind status may contribute to the lower social cognition.

How joint attention relates to cooperation in 1- and 2-year-olds

Joint attention has been suggested to contribute to children’s development of cooperation; however, few empirical studies have directly tested this hypothesis. Children aged 1 and 2 years participated in two joint action activities to assess their cooperation with an adult partner, who stopped participating at a specific moment during the tasks. Children’s joint attention skills were measured by the Early Social Communication Scales (ESCS). Results showed that children’s responding to joint attention ability contributed to their successful cooperation in an activity that required parallel roles, whereas initiating joint attention ability contributed to their successful cooperation in an activity that required complementary roles. These results suggest a complex relationship between joint attention and cooperative abilities when considering RJA and IJA separately.
