correlational study

For the studies described below PLEASE NO PLAGARSIM

Answer the following questions

1. This is a correlational study. Identify what kind of correlation and provide ONE explanation for these findings.

One study found a +0.67r(correlation) that people who were abused as children were more likely to abuse their own children.

2. The following is a conclusion drawn from the Experiments. Based on your knowledge of experiments, identify how this experiment was likely carried out including: the Experimental Group, the Control Group, the Independent Variable (IV), and the Dependent Variable (DV). Identify ONE control the researcher would have had to have to make the study possible. (8 points)

Finding: People remember concrete words better than abstract ones.

3. ETHICS: Instructions: You are part of the Animal Care Committee for your university. It is the committee’s responsibility to evaluate and either approve or reject research proposals submitted by faculty members who want to use animals for research or instructional purposes in psychology, biology, or medicine. The proposals describe the experiments, including the goals and potential benefits of the research as well as any discomfort or injury that they may cause the animal subjects.

You must either approve the research or deny permission for the experiments. It is not your job to suggest improvements on technical aspects of the projects, such as the experimental design. You should make your decision based on the information given in the proposal. Provide ONE reason for your decision. (6 points)

Dr. Fine is a developmental psychobiologist. His research concerns the genetic control of complex behaviors. One of the major debates in his field concerns how behavior develops when an animal has no opportunity to learn a response. He hypothesizes that the complex grooming sequence of mice might be a behavior pattern that is built into the brain at birth, even though it is not expressed until weeks later. To investigate whether the motor patterns involved in grooming are acquired or innate, he wants to raise animals with no opportunity to learn the response. Rearing animals in social isolation is insufficient because the mice could teach themselves the response. Certain random movements could accidentally result in the removal of debris. These would then be repeated and could be coordinated into the complex sequence that would appear to be instinctive but would actually be learned. To show that the behaviors are truly innate, he needs to demonstrate that animals raised with no opportunity to perform any grooming-like move­ments make the proper movements when they are old enough to exhibit the behavior.

Dr. Fine proposes to conduct the experiment on 10 newborn mice. As soon as the animals are born, they will be anesthetized and their front limbs amputated. This procedure will ensure that they will not be reinforced for making random grooming movements that remove debris from their bodies. The mice will then be returned to their mothers. The animals will be observed on a regular schedule using standard observation techniques. Limb movements will be filmed and analyzed. If grooming is a learned behavior, then the mice should not make grooming movements with their stumps as the movements will not remove dirt. If, however, grooming movements are innately organized in the brain, then the animals should eventually show grooming-like movement with the stumps.

In his proposal, Dr. Fine notes that experimental results cannot be directly applied to human behavior. He argues, however, that the experiment will shed light on an important theoretical debate in the field of developmental psycho­ biology. He also stresses that the amputations are painless and the animals will be well treated after the operation.
