Exam 2: Studying Behaviour Scientifically

Susan is interested in whether or not college students are prejudiced against elderly people. She has students come into the lab, view the faces of elderly people, and make judgments about the emotion displayed by each face. Susan tells participants that they are working on an emotion recognition experiment; however she is actually measuring The number of negative emotions assigned to the elderly faces. Susan's proposed research involves which of the following violations of the ethical standards in human research?

A researcher is interested in studying what factors influence interpersonal attraction. In a study designed to explore this variable, the researcher uses a very attractive person for an assistant. Interpersonal attraction is then assessed by whether the people participating in the study call up the attractive assistant to ask the person on a date. In this example, the means used to assess interpersonal attraction would be considered a(n):

An animal researcher is studying the effect of a new drug on the memory of mice. One group of mice receives the drug while a second group does not. The memory of the mice is then tested by how quickly they can negotiate a previously learned maze. In this Example, the group of mice that does not receive the drug would be considered the:

People sometimes change their behaviour when they know that they are being observed. To counter this problem, psychologists monitor behaviours in a way that people are unaware that they are being observed. These measures are called _.

Jake and Jack are both interested in the effect of the loud music from the dorm room next door on their grades. Jake records the days and hours the music is loud and compares that information to the grades he received on exams taken the days following the loud music. Jack plays his own music loud before his first psychology exam and quietly Before his second exam. He then compares his exam scores.

A researcher wants to know how much time students in a dorm spend watching TV, but she has noticed that students tend to leave the TV room when she comes in to see who is watching. To get around this problem, she decides to observe wear-and-tear on the TV remote control as a measure of how much time students spend watching TV.

In a study of aggression, Dr. Berkowitz had participants watch either violent or non-violent media after they had been frustrated by a colleague. They were then able to deliver electric shocks to the colleague as feedback for mistakes made on a memory test. Berkowitz recorded the intensity of shocks delivered. Results indicated that more intense shocks were given when participants watched the violent media. In this study, the Independent variable is ________ and the dependent variable is _.
