Before John B. Watson suggested that behavior be the subject matter of psychology, psychologists and philosophers studied the “mind” and referred to other internal events to explain behavior. Explain why these references are unreliable, and describe how behavior analysis explains behavioral events. 

Explain why natural selection is an analogy for shaping. Identify all three conditions required of both evolutionary processes in your response.

Given the scenario below, explain how the behavioral activity of kicking a soccer ball developed using the law of effect and shaping. Be sure to include the three conditions included from Question #5. Nora grew up playing soccer in her backyard with her younger sister, Rosie. When Nora first started to learn how to kick a ball, she did not apply enough force, and the ball did not go very far. She slowly learned how hard to kick to pass the ball to Rosie. However, she was not always good at aiming. After kicking the ball, it would go far enough but not towards Rosie. She began to learn how to aim the ball and kick hard enough to make it to Rosie. When Nora was old enough, she began to play soccer with a team. She learned how to kick a ball when she is trying to score a goal, pass to a teammate, and kick it out of her team’s penalty box. All of these types of kicks require different types of kicking. When kicking the ball out of the penalty box, she would kick it with the top of her foot to ensure it landed far away from her team’s goal. When kicking the ball to pass to a teammate, Nora uses the inside of her foot to keep the ball low to the ground. Finally, when she is trying to score a goal, Nora kicks the ball with the inside of her foot but with more force than during a pass. Now, Nora plays soccer on her high school soccer team and can distinguish when to use each type of kick.
