Question 1

Which of the following is one of Pennebaker's recommendations for writing to improve your health?

Accepted Answer

The answer of Which of the following is one of...

Question 2

Which of the following research studies can establish TRUE cause and effect relationships?

Accepted Answer

Experiments are designed to test hypotheses under controlled conditions, allowing researchers to manipulate variables and determine cause and effect relationships. Surveys and correlational studies can suggest associations but cannot establish causality due to potential confounding variables.

Question 3

The _________ variable is manipulated by the experimenter to determine its effect on another variable.

Accepted Answer

The independent variable is the one that is manipulated or changed by the researcher to observe its effects on the dependent variable.

Question 4

The _________ variable is a measure of the results of an experiment.

Accepted Answer

The dependent variable is the variable that is being measured or tested in an experiment. It is the outcome that changes in response to the manipulation of the independent variable.

Question 5

In an experiment, the cause is the ________ variable, and the effect is the _______ variable.

Accepted Answer

In an experiment, the independent variable is manipulated by the researcher to observe its effect on the dependent variable, which is the outcome of interest.

Question 6

In his experiment, Pennebaker wanted to find out if writing about emotions would cause improvements in a person's physical health. Writing about emotions would be the:

Accepted Answer

In Pennebaker's experiment, writing about emotions is the independent variable because it is the condition manipulated by the researcher to observe its effect on the dependent variable, which in this case would be improvements in a person's physical health.

Question 7

In his experiment, Pennebaker wanted to find out if writing about emotions reduced the number of visits that the participants made to the college health center. The number of visits to the college health center would be the _____ variable in this experiment.

Accepted Answer

The number of visits to the college health center is the dependent variable because it is the outcome that is being measured to see if it changes in response to the manipulation of the independent variable (writing about emotions).

Question 8

If an experimenter wanted to find out if teaching students time management training would improve their semester grades, the time management training would be the ________ variable.

Accepted Answer

The independent variable is the variable that is manipulated or changed in an experiment to see if it has an effect on another variable. In this case, the time management training is what is being manipulated to see if it affects students' semester grades.

Question 9

If an experimenter wanted to find out if teaching students time management would improve their semester grades, the students' semester grades would be the ________ variable.

Accepted Answer

The students' semester grades would be the dependent variable because they are the outcome that the experimenter is trying to measure or predict based on the manipulation of the independent variable, which in this case would be teaching students time management.

Question 10

If an experimenter wanted to find out if taking a multi-vitamin daily reduced the number of colds experienced by students during the fall semester of school, taking the daily multi-vitamin would be the _______ variable.

Accepted Answer

The independent variable is the variable that is manipulated or changed in an experiment to see if it has an effect on another variable. In this case, taking a daily multi-vitamin is the variable being manipulated to observe its effect on the number of colds, making it the independent variable.

Question 11

If an experimenter wanted to find out if taking a multi-vitamin daily reduced the number of colds experienced by students during the fall semester of school, the number of colds experienced by the students would be the _______ variable.

Accepted Answer

The number of colds experienced by the students is the dependent variable because it is the outcome that the experimenter is measuring, which is expected to change as a result of manipulating the independent variable (taking a multi-vitamin daily).

Question 12

In an experiment, the group of subjects that receives the independent variable or treatment is called the ______ group.

Accepted Answer

The experimental group is the group in an experiment that receives the independent variable or treatment, to test its effect compared to a control group that does not receive the treatment.

Question 13

In an experiment, the _______ group does not receive the independent variable but serves as a comparison group or baseline against which the effects of the manipulated condition can be compared.

Accepted Answer

The control group in an experiment is the group that does not receive the independent variable and is used as a baseline to compare the effects of the manipulated condition, helping to isolate the effects of the independent variable.

Question 14

In the Pennebaker experiment concerned with the effects of emotional writing on physical health, the group of participants that wrote about their emotional experiences was the _______ group.

Accepted Answer

The experimental group in an experiment is the group that receives the treatment or intervention under study, which in the Pennebaker experiment was the group that wrote about their emotional experiences.

Question 15

In the Pennebaker experiment concerned with the effects of emotional writing on physical health, the group of participants that wrote only about non-emotional topics was the _______ group.

Accepted Answer

The control group in an experiment is the group that does not receive the experimental treatment and is used for comparison. In the Pennebaker experiment, the group that wrote about non-emotional topics served as the control group to compare against those who wrote about emotional topics.

Question 16

In an experiment to determine if taking an aspirin a day reduces circulatory problems, the control group would take:

Accepted Answer

In a scientific experiment, the control group is used as a baseline to compare against the experimental group. The control group should not receive the experimental treatment. In this case, since the experiment aims to determine if taking an aspirin a day reduces circulatory problems, the control group should not take any aspirin, making option D the correct choice.

Question 17

An experimenter wants to determine whether students who are trained to use memory aids make better scores on a memory test than students who are not trained to use memory aids. The experimenter provides two hours of training to one group of subjects. This group that received the training is the _______ group.

Accepted Answer

The group that receives the training in an experiment is referred to as the experimental group because they are exposed to the treatment or condition being tested, in this case, training to use memory aids.

Question 18

In order to reduce the likelihood that the experiment's results will be due to any preexisting differences between groups, the participants in a study are placed in the experimental and control based on:

Accepted Answer

Placing participants in experimental and control groups based on chance (random assignment) is the method used to reduce the likelihood that the experiment's results will be due to any preexisting differences between the groups. This ensures that each participant has an equal chance of being assigned to any group, minimizing bias and making the groups as similar as possible at the start of the experiment.

Question 19

Jeffery wanted to make sure that the preexisting condition of motivation would not affect his experiment on the effects of study skills on grades. He should:

Accepted Answer

Random assignment of subjects to the experimental and control groups is the best way to ensure that preexisting conditions, such as motivation levels, are evenly distributed across both groups. This method minimizes the impact of confounding variables, like motivation, on the experimental outcome.

Question 20

If there is a correlation between self-esteem and success, we can conclude that:

Accepted Answer

Correlation indicates an association or relationship between two variables, but it does not imply causation. Therefore, knowing there is a correlation between self-esteem and success only tells us that these two factors are related in some way, not that one causes the other.
