Question 1

Quasi-experimental designs can include all of the following except

Accepted Answer

Quasi-experimental designs do not include random assignment, which is a key feature of true experimental designs.

Question 2

Basic research is to applied research as ______ is to _______.

Accepted Answer

Basic research is focused on gaining knowledge and understanding fundamental principles, while applied research is aimed at solving specific, practical problems.

Question 3

What is the relationship between applied research and theory testing?

Accepted Answer

Applied research often tests theories by applying them to real-world problems, thus its results can directly impact the evaluation of those theories.

Question 4

Applied research

Accepted Answer

Applied research was important to American psychologists from the beginning of psychology in the U.S., as they were interested in practical applications of psychological principles.

Question 5

Experiment is to quasi-experiment as _____ is to _____.

Accepted Answer

In an experiment, equivalent groups are typically used to ensure that any differences observed are due to the treatment. In a quasi-experiment, groups are often nonequivalent because random assignment is not used.

Question 6

A nonequivalent control group design usually (but not necessarily)includes

Accepted Answer

A nonequivalent control group design typically includes pretests to compare groups before treatment, but it does not use random assignment, does not allow for causal conclusions, and involves more than a single group.

Question 7

In a nonequivalent control group study,

Accepted Answer

In a nonequivalent control group study, all the listed characteristics are true: the groups differ systematically, one group receives treatment while the other does not, and comparisons are made based on changes from pretest to posttest.

Question 8

In a study comparing two nonequivalent groups, a selection by history confound occurs when

Accepted Answer

A selection by history confound occurs when an external event affects only one of the groups between the pretest and posttest, leading to differences that are not due to the treatment or intervention being studied.

Question 9

Early psychologists often tried to adapt laboratory methods to solve applied problems. For instance, Stanford psychologist Walter Miles tried to help the football team by adapting which method?

Accepted Answer

Walter Miles adapted the reaction time method to help the football team by measuring players' reaction times to improve their performance.

Question 10

In a nonequivalent control group study,

Accepted Answer

In a nonequivalent control group study, the experiment group gets a pretest, then the experimental treatment, then a posttest.

Question 11

Applied research done in a field setting

Accepted Answer

Applied research in a field setting often has stronger external validity because it is conducted in real-world environments, making the findings more generalizable. However, it may have weaker internal validity due to less control over extraneous variables.

Question 12

Applied research

Accepted Answer

The answer of Applied research
...

Question 13

Applied research

Accepted Answer

Applied research focuses on solving specific, practical problems in the real world, often using theories to guide the investigation.

Question 14

Which of the following is true about the Hollingworth's Coca-Cola study?

Accepted Answer

The Hollingworth's Coca-Cola study used placebo controls and a double-blind procedure to ensure the validity and reliability of their findings.

Question 15

Random assignment is used in

Accepted Answer

Random assignment is not used in a nonequivalent control group design or an interrupted time series design. These designs typically involve pre-existing groups or observations over time without random assignment.

Question 16

The study by Trudel et al. (2015)on color-coded nutrition labels shows that

Accepted Answer

The study by Trudel et al. (2015) demonstrates that applied research, such as the use of color-coded nutrition labels, can provide empirical support for basic psychological phenomena by showing how these labels influence consumer behavior, thus linking applied findings to basic psychological principles.

Question 17

When psychology first emerged as an independent discipline at the end of the nineteenth century, American psychologists

Accepted Answer

American psychologists felt it necessary to demonstrate the practical utility of psychology to gain acceptance and support for the new discipline.

Question 18

Which of the following was true about Trudel et al.'s (2015)study on color-coded nutrition labels?

Accepted Answer

The answer of Which of the following was true about...

Question 19

Consider the methodological principles you have learned about so far. The Hollingworth's Coca-Cola study incorporating several of these principles. Which of the following did they not use in their study?

Accepted Answer

The Hollingworth's Coca-Cola study did not use a factorial design. They used a double-blind procedure, a placebo control condition, and counterbalancing to ensure the validity and reliability of their results.

Question 20

What makes a nonequivalent control group design a quasi-experimental design?

Accepted Answer

In a nonequivalent control group design, random assignment is not possible, which is why it is considered a quasi-experimental design.
