While playing in the backyard one day, the neighbor’s dog wandered over. Your playmate, who has a tremendous fear of dogs, let out a bloodcurdling scream, yanked you cruelly by the arm, and dragged you into the house. You no longer want to go outside to play because you are afraid of the “neighbor’s dog.” In this example, discuss the conditioning process that has taken place and identify each of the elements in the process. Answer: In this example, classical conditioning of a phobia has occurred. The UCS was my playmate’s scream (possibly paired with the pain of being dragged into the house). The scream caused me to have an immediate fear response (the UCR). The dog was a previously neutral stimulus that became coupled to the scream. The dog has become a CS, which is associated with the backyard. The CR is my fear of dogs (and secondarily, the backyard). 199. Explain the suggestion that “phobias are initially classically conditioned but are maintained over time through avoidance conditioning.” Use an example to illustrate. Answer: (NOTE: Student answers will vary.) Assume that I have a fear of mice. As a small child, I was playing on the kitchen floor when I saw a mouse scurry by. Curious, I started to approach it. At the same time, my mother saw the mouse and began to scream and jump on a kitchen chair. Her behavior frightened me and I started to cry. In this example of classical conditioning, my mother’s scream was the UCS, which caused a fear response in me (the UCR). I associated her scream with the mouse (the CS). The CR is my fear of mice. To maintain the phobia, I now go out of my way to avoid mice. By modifying my behavior to avoid this stimulus (the mouse), I continue to negatively reinforce my staying away from mice, because I never see that mice are not associated with my mother’s scream. 200. A parent wants to reinforce her child for brushing her teeth all by herself. Describe the four types of reinforcement schedules, other than continuous reinforcement, that the parent could use, and give an example of how the parent could use each. Answer: (NOTE: Student examples will vary.) There are four reinforcement schedules. In a fixed interval schedule, a person is rewarded after a set interval of time. For example, the parent would reinforce the child the first time she brushes her teeth every three days. In a variable interval schedule, a person is reinforced after a variable time interval. For example, the parent would reinforce the child the first time she brushes her teeth by herself after 4 days, then 8 days later, and then 2 days after that. With a fixed ratio schedule, reinforcement follows a set number of behavioral responses. For example, the parent reinforces the child after every five times of brushing her teeth by herself. With a variable ratio schedule, reinforcement follows a varying number of responses. For example, the parent would reinforce the child after brushing her teeth by herself two times, then after another 7 times, then after another 4 times, and so on. 201. You are carrying a heavy load of books in your arms. As you get to the car, you struggle to get your keys from your pocket to unlock the car and drop the books on your foot. The result is a broken toe. Soon after, you buy yourself a backpack. In this example, explain what type of conditioning occurred when you dropped the book. Next, explain what type of conditioning is occurring when you use your backpack. Answer: When the books fell on my foot, I was punished. A behavior (carrying too many books) was followed by an aversive stimulus (a broken toe). When I use my backpack I am reinforcing behavior through negative reinforcement-avoidance conditioning. I anticipate that carrying too many books will cause me pain, so I do a behavior (using a backpack) to avoid the negative stimulus (another broken toe). 202. Write about two practical applications of taste aversions. You may use examples from your text or develop your own examples. Answer: (NOTE: Student answers will vary.) Two examples of practical applications are cited in the text. In chemotherapy patients, patients are encouraged not to eat prior to a treatment in order to avoid the development of aversions. In the West, Garcia and colleagues developed an environmentally and animal-friendly way to control the loss of sheep to ranchers from the coyote population. By lacing some mutton with nausea-inducing drugs, coyotes developed taste aversions to sheep. This procedure substantially reduced herd loss for ranchers.
