Question 1

A patient who recently lost a job shows a sudden increase in interest in learning new skills and setting career goals. Which theory of motivation best explains this behavior?

Question 3

A teacher observes that a 7-year-old student consistently fails to understand that the amount of liquid remains the same when poured from a tall, thin glass into a short, wide glass. According to Piaget's theory, which cognitive characteristic is this student most likely demonstrating?

Accepted Answer
