Numerical Cognition Project

I have a general interest in numerical cognition. This is partially because of my frustrated experience of learning math in the primary school. I want to find out what kind of factors may determine the learning outcome of math (although I already know a grumpy teacher will definitely lead to a negative result) and I want to understand the neural basis of numerical cognition. Specifically, I am interested in understanding the role of attention system in subitizing and how subitizing plays a fundamental role in the development of numerical cognition and math ability.

Addictive Behaviour Project

For too many times I am amazed by how addictive the new social media (TikTok) could be. Recent studies have shown that many factors/motivations are associated with the addictive use of social media. Nevertheless, little is known about how these factors/motivations drive individual’s addictive use of social media and there is no systematic investigation of the underlying mechanisms. Understanding these factors driving the addictive use of TikTok has practical implications in improving young adults’ mental health. The purpose of this project is twofold. First, I want to develop a tool to measure the addictive use of social media. Second, it is my interest to find out the predicting factors and protective factors for addictive use of social media.

Schizophrenia Project

I have worked on the schizophrenia stigma project for a while. This research interest emerges from my internship in a general hospital in China. Through conversation with many mental illness patients, I get to know how hard their life could be. The purpose of this project is to help reduce the stigma of schizophrenia in Chinese context.

This is a book I translated into Chinese. The motivation of this work is to provide more reading materials for the patients with schizophrenia and their families. This book has a 99% positive review so far. You can buy this book from any book stores in China and e-commerce platforms such as

2, First paper

This paper aims to review and challenge the Chinese translated name of schizophrenia. It is the first paper to thoroughly discuss this issue in the mainland China. This paper is published in a Chinese journal in 2019.

3, Second paper

With the help of my colleagues in China, we conducted a study to investigate whether a change of diagnostic name of schizophrenia can improve public perception and attitude toward it. Our findings are simple: the change of diagnostic name of schizophrenia does improve people’s understanding of this mental illness and attitudes toward patients with schizophrenia. This paper is in preparation.
