Human Growth and Development Theories

The video opens with a scenario of three-year-old Timmy insisting on making his own breakfast and reacting angrily when his mother tries to help. This scenario sets the stage for developmental psychologists to explain behaviors occurring throughout life, using various theories to understand human growth and change.

Psychoanalytic theory, a highly influential theory, focuses on unconscious motivations and the impact of early experiences. Theorists like Sigmund Freud (psychosexual development) and Erik Erikson (psychosocial development) are key figures. While strong in recognizing unconscious drives and early experiences, its ideas are difficult to empirically test, leading to a lack of substantial research support. Applying this to Timmy, psychoanalytic theory might suggest he is seeking independence, an age-appropriate behavior.

In response to the difficulty in testing psychoanalytic claims, learning theories emerged, focusing on measurable and quantifiable behaviors. This approach examines how behavior is learned. Ivan Pavlov's classical conditioning, B.F. Skinner's operant conditioning, and Albert Bandura's social learning theory are discussed as examples. The strength of these theories lies in their testability and practical application. However, a weakness is their tendency to overlook genetic processes and developmental changes across the lifespan. In Timmy's case, learning theory might explain his behavior as a learned response where his mother's attention reinforces his 'acting out' behavior.
