Exam 2: Studying Behaviour Scientifically

In a negative correlation,higher scores on one variable are associated with ____________ scores on a second variable.

The procedure that ensures that all subjects have an equal chance of being in any group or condition within the experiment is called:

When the researcher observes behaviour as it occurs in a normal or typical setting,she is using _______________.

The problem that occurs when we can't tell which of two variables causes the other (i.e. ,does A cause B or does B cause A)is called the third-variable problem.

An educational psychologist wants to study the effectiveness of using the Internet as a way of taking academic classes.She designs a study in which one group of students is assigned to take a course in a standard classroom with a live instructor.Another group of students is assigned to take the same course over the Internet.The psychologist then compares the course grades for students in each of the two groups.In this case,the instruction group (regular class vs.Internet class)would be considered the ____________ variable.

You study 100 children for a month,measuring how much TV they watch and how many aggressive acts they perform.You find that TV watching and aggression are highly and positively correlated.Based on this study,you can:

An important advantage of naturalistic observation is that it can:

A researcher is examining the relation between two variables: variable X and variable Y.If she is conducting a correlational study,the researcher ____________ variable X and ____________ variable Y.

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

Because people or animals sometimes change their behaviour when they know they are being watched,researchers often make use of ____________ measures of behaviour in order to avoid this problem.

Which of the following best represents a good scientific attitude? Science:

A procedure in which every member of a population has an equal probability of being selected to participate in the study is called

A hypothesis is best considered as a(n):

If there is a strong correlation suggesting that more parental involvement is associated with fewer behaviour problems for children,which would be the most likely correlation coefficient?

Designs in which each participant is exposed to each condition or group in an experiment,control for individual differences by _________________________.

Initially,people or animals may behave differently if they are being watched,but,over time,they become acclimated to the presence of an observer and their behaviour returns to normal.This process is specifically referred to as:

Numerous researchers have conducted research examining the effect of media violence on aggression.Which of the following would you want to conduct to reach an overall conclusion about the phenomenon?

The process of repeating an experiment to determine whether the same results can be obtained is called _________.

When two variables have been combined in such a way that we can't determine which one had an effect on the dependent variable,this means the variables are ___________________.

A young man is interested in making a good impression on the parents of the person he is currently dating.Because of this,when he meets them he overemphasizes his good qualities and ignores many of his shortcomings.This man's behaviour is most relevant to which of the following concepts?
