Working Memory and Social-emotional Training for Preschoolers at Risk of ADHD

Summary

The study aims to explore the effectiveness of working memory training and social emotional training for young children with ADHD in Hong Kong. This study will contribute to the current understanding of the alternative treatments for ADHD, and hopefully help to mobilize more resources to be dedicated to the support of children with ADHD. The programme includes the following components:

Children participating in this study will be randomly allocated into experimental group - recieving working memory training, active control group - receiving social-emotional training, and waitlist control group. All participants will complete a 5-week online training using a digital device at home, three times a week, each training session lasts for about 15 minutes.

Moreover, children's cognitive abilities and academic performance will be assessed prior to the intervention, and immediately after the 5-week training. Each assessment session lasts for about 45 minutes. Parents will also be asked to fill out a questionnaire on children's behaviours at home and school prior to and after the 5-week program. It takes about no more than 10 minutes. All assessments will be conducted at the laboratory at the University of Hong Kong.

Children's working memory, time perception, ADHD symptoms, and early academic performance will be measured before and after training, and the between-group performance will be compared to examine the training effects.

Interventions

BEHAVIORAL

Game-like online working memory training

Participants in the WM group will be receiving two types of WM training tasks (two mini-games) in each session. Half of the training time will be spent on playing a game that requires visual-spatial WM, and the other half of the training time will be spent on playing a game that demands verbal WM. In both the games, the participant is asked to remember the pictures or audios (numbers) presented, and then recall them and select them on the screen.

BEHAVIORAL

Game-like online social emotional training

Participants in the SE group will be also receiving two types of SE training tasks in each session, to match with the ones in the WM training. There are two mini-games for training. To match with the spatial-visual WM training, participants in the SE group will be asked to first look at a picture that depicts a daily social scenario (i.e., a child who fell down and hurt himself), and then to choose an emotion that the child in the picture may feel from four options of facial emotions displayed on the screen. The other mini-game, with the aim to match with the auditory WM training, will first tell a short story of a social scenario (i.e. "David accidentally fell down and got hurt), and then will ask the child to choose the emotion that the character in the story may feel from the four options displayed on the screen. Each mini game lasts for about 7 minutes in each training session.
