- Lim Zia Huei kept journals on social psychology concepts from her class, including social facilitation, social loafing, self-serving biases, self-fulfilling prophecy, and operant conditioning.
- For social facilitation, she found she works harder in groups when others can see her efforts. For social loafing, some group members were lazy when individual efforts couldn't be identified.
- She exhibited self-serving biases by taking credit for successes and blaming outside factors for failures. High expectations from others led her to fulfill the self-fulfilling prophecy of getting good grades.
- Her mother used operant conditioning principles of rewards and punishments to motivate her and her brother to study hard
