About this course

Technological advances present us with a unique opportunity to dramatically enhance our understanding of human behavior. How do people describe their thoughts, feelings, and their lives when unencumbered by the measurement biases and sampling issues inherent in psychological surveys? What can we learn by exploring the nature of the human condition, from personality, to political attitudes, to cognitive functions, to healthy or unhealthy behaviors, through the lens of Big Data?

In this course, we will discuss cutting-edge research on psychoinformatics, an interdisciplinary field where data science and technology meet the human mind. We will explore the theory and research underlying computational models of psychological processes, big data analytics and machine learning techniques for psychological data, and the social, cultural, and ethical implications of human-computer interactions.
