  • 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.
