Exam 2: Studying Behaviour Scientifically

Shireen thinks that people learn better when they enjoy the course in which they are studying.In order to test her prediction,she must operationalize her variables.Which of the following best represents valid operational definitions of the variables contained within her prediction?

Assume that there is a strong negative correlation between two variables: variable 1 and variable 2.If you know that a person's score on variable 1 is low,what would be your best prediction for the person's score on variable 2?

The major drawback of ____________ understanding is that there are many different ways to explain the causes of events and we can never be sure which explanation is correct.

Amy conducts an experiment in which she discovers that brunettes have more fun.She has three brunette females and three blond females go to the same party and record how many times they were asked to dance.In her experiment,Amy has defined the dependent variable as the number of times they were asked to dance,and the ___________ as hair colour.

Instead of hindsight understanding,scientists prefer to use ____________ and control in order to gain knowledge.

One of the problems with experiments that have found evidence for paranormal phenomena is that they have:

According to the results of the study done by John Darley and Bibb Latané,if you are robbed at gunpoint while walking home from the grocery store,your best chance of receiving help from witnesses would be when:

One of the problems of after-the-fact or "hindsight" explanations is that:

John Darley and Bibb Latané made the assumption that a diffusion of responsibility reduces the likelihood that any one bystander would feel responsible for helping in an emergency.This assumption is an example of a(n)_________.

If an experimental procedure involves deception then what are the ethical obligations of the experimenter toward the participants?

If an experiment has a confounding variable,this significantly lowers its internal validity.

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:

The placebo effect refers to:

One of the problems with collecting data over the internet is:

Number of kicks and/or hits in a 2 minute interval is an example of a(n)____________ of aggression.

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 _________.

An important limitation of the case study research method is that it:

What are the three essential characteristics of experimentation?

A researcher,who is always willing to consider criticisms of his theory and to make theoretical revisions and adjustments when the evidence supports it,is demonstrating behaviour most consistent with which key scientific attitude?

In an experiment,a group that is not exposed to the treatment or that receives a zero-level of the independent variable is called the ____.
