HL students must also investigate the following topics in relation to the four contexts above:

• The role of culture in shaping human behaviour – Students investigate how local and global cultures shape human behaviour, including the impact of globalization on mental health and identity across various populations
• The role of motivation in shaping human behaviour – Students examine the conscious and unconscious impetus behind behaviour, differentiating between primary physiological needs and secondary social goals while exploring theories like self-determination.
• The role of technology in shaping human behaviour – Students analyze the significant influence of digital tools, such as artificial intelligence and social media, on human behaviour, mental health, and interpersonal relationships.
• Data analysis and interpretation – Students develop the critical skills necessary to analyze, interpret, and draw reasoned conclusions from both quantitative and qualitative research findings to support conceptual understanding.
