Mapping the evolution of research agendas in Chinese psychology: An LDA topic-modelling analysis of two core journals, 2003–2025
This study utilizes Latent Dirichlet Allocation (LDA) topic modelling on nearly 7,000 articles from two core Chinese psychology journals (2003–2025) to reveal a research agenda evolution from basic cognition toward mental health and digital technologies, characterized by thematic continuity and a stable functional division between empirical development in *Acta Psychologica Sinica* and theoretical synthesis in *Advances in Psychological Science*.

Psychology is the science of the mind, but it does not exist in a vacuum. It grows and changes just as the societies that produce it do. In China, the field has undergone a massive transformation over the last two decades, shifting from a focus on building basic scientific foundations to tackling complex, real-world problems like mental health, social behavior, and the impact of technology. To understand how a scientific discipline evolves, researchers often look at the topics scientists choose to study. They examine the "research agenda," which is simply the collection of questions, problems, and methods that a field prioritizes at any given time. By tracking these priorities over time, we can see not just what psychologists are studying, but how their thinking is adapting to new challenges, new tools, and a changing world.
A team of researchers set out to map this evolution within Chinese psychology. They focused on two of the country's most important academic journals, Acta Psychologica Sinica and Advances in Psychological Science. These publications serve as the primary windows into the field, one specializing in original experiments and the other in reviewing and synthesizing new knowledge. The team gathered nearly 7,000 articles published between 2003 and 2025. Instead of reading every single paper manually, they used a computer method called topic modeling. This technique acts like a sophisticated sorting machine that reads the text of thousands of articles to find hidden patterns. It groups words that frequently appear together to identify the main themes or "topics" that researchers are discussing, allowing the team to see how these themes rise, fall, and change over time without human bias.
The analysis revealed that the history of Chinese psychology over these twenty-two years did not follow a simple path where old ideas were simply thrown away to make room for new ones. Instead, the field expanded and reorganized itself. The study divided the timeline into three distinct eras. The first era, from 2003 to 2012, was a period of foundation building. During these years, the research agenda was dominated by basic questions about how the human mind works. Scientists were deeply focused on memory, attention, and how children develop. The work was largely experimental, aiming to establish standard ways of testing the mind and aligning Chinese research with international standards. The second era, from 2013 to 2021, marked a shift toward application. While the basic questions about memory and attention remained important, the agenda broadened significantly. Researchers began to turn their attention to mental health, social emotions, and how culture influences thinking. The focus moved from the laboratory to the real world, addressing issues like well-being, decision-making, and the psychological effects of social interactions.
The third era, covering 2022 to 2025, introduced a new layer of complexity driven by technology. The research agenda in this recent period shows a strong integration of digital tools and artificial intelligence. Scientists are now exploring how people behave in online environments, how machine learning can help analyze psychological data, and how to synthesize evidence from many different studies to find clearer answers. This is not a replacement of the earlier work but a building upon it. The foundational studies on memory and attention are still present, but they are now being combined with new methods and applied to modern problems like digital addiction, social media influence, and the use of big data. The evolution suggests a field that is becoming more versatile, using advanced technology to solve the same fundamental human questions in new ways.
The study also uncovered a clear division of labor between the two journals they analyzed, which helps explain how the field stays organized. Acta Psychologica Sinica acted as the engine for new, specific discoveries. It consistently published studies that tested new ideas, developed new experiments, and explored specific problems in real-world settings. It was the place where the field moved forward by testing the boundaries of what was known. In contrast, Advances in Psychological Science served as the field's mapmaker. It focused on reviewing existing research, connecting different studies, and creating broader theories that explained how various findings fit together. While one journal pushed the frontier of specific experiments, the other worked to organize those experiments into a coherent body of knowledge. This partnership allowed Chinese psychology to grow rapidly without losing its direction; the experimental journal kept the field moving, while the review journal kept it grounded and connected.
Ultimately, the research suggests that the development of psychology in China is a story of continuity and adaptation. The field did not abandon its roots in basic science to chase trends. Instead, it kept its core focus on understanding the mind while gradually expanding its toolkit to include social issues, cultural contexts, and digital technologies. The shift from a focus on pure theory to a blend of theory, application, and technology reflects a discipline that is maturing and responding to the needs of a rapidly changing society. By looking at the long-term patterns of what scientists choose to study, this analysis shows that the evolution of a scientific field is rarely a sudden break from the past. It is a steady process of adding new layers to old foundations, ensuring that the science remains relevant to the world it seeks to understand.
