Baby Carlos is playing with a shape-sorting toy. At first, he tries to fit every block in every opening until one fits. After a week, Carlos is able to get most of the blocks into the correct opening on the first try. What type of learned behavior is this?

Carlos first tries different openings until he finds one that fits, which is trial-and-error learning. With practice, he learns which opening matches each block and can choose correctly on the first try. Conditioning involves learning through associations or consequences, while instinct is an inborn behavior.
