Question 1

Case studies help researchers:

Accepted Answer

Case studies provide in-depth information about individual cases, which can then be used to make general inferences about the sources of psychopathology. They are not typically used to focus on unconscious motivations and conflicts, measure overt behaviors, or eliminate biological factors from potential causes of psychopathology.

Question 2

Which of the following statements is true of the ethical issues involved in research?

Accepted Answer

Researchers should debrief participants after the study, explaining any deception used, to ensure ethical standards are maintained and participants are fully informed.

Question 3

Correlational studies:

Accepted Answer

Correlational studies do not involve the manipulation of variables, they simply observe the relationship between variables without attempting to establish cause and effect.

Question 4

Dr. Peters investigated the relationship between academic performance of middle school students and the absence of recess. The study revealed that students who were allowed recess had higher performances. This study is indicative of a:

Accepted Answer

The study showed that there was a relationship between recess and academic performance, and that relationship was positive, indicating that higher amounts of recess was associated with higher academic performance.

Question 5

Which of the following represents a perfect correlation?

Accepted Answer

A perfect correlation means that the two variables have a linear relationship with a consistent direction and a strength of 1.0 or -1.0. Therefore, the best choice is B, which includes the values of -1.0 and +1.0. The other choices include values that are too high or too low for a perfect correlation.

Question 6

Luther realized that the more he engaged in outdoor activities, the less time he spent playing video games. This is an example of a _____.

Accepted Answer

A negative correlation means that as one variable increases, the other variable decreases. In this case, Luther's engagement in outdoor activities is negatively correlated with his time spent playing video games. As he engages more in outdoor activities, his time spent playing video games decreases.

Question 7

Which of the following statements is true about case studies?

Accepted Answer

Case studies are particularly useful for capturing the complexity and uniqueness of an individual's experiences and perspectives. They allow for a deep understanding of the context and factors surrounding a particular phenomenon or behavior. However, they may not be generalizable to other individuals or groups. Additionally, there may be some subjective bias on the part of both the researcher and the participant, which can impact the validity of the findings.

Question 8

A detailed history of an individual who has suffered a psychological disorder is called a(n) _____.

Accepted Answer

A case study is a detailed history of an individual who has suffered a psychological disorder. It involves the in-depth examination of a particular person or group and their psychological condition, symptoms, treatment, and outcomes. Case studies are commonly used in clinical psychology and psychiatry to help understand and treat specific psychological disorders.

Question 9

Which of the following statements is true of the ethical issues involved in research?

Accepted Answer

It is true that individuals who are not capable of understanding the risks of a study, such as children, must have a parent, guardian, or other responsible adult make the decision about their participation in the study. This is because they cannot understand the risks and benefits of participation and therefore require someone to make the decision on their behalf. The other options are false. Participants are always allowed to withdraw their participation, written consent is not always mandatory, and deception can only be justified in limited circumstances.

Question 10

Cross-sectional studies observe:

Accepted Answer

Cross-sectional studies observe groups at only one point in time.

Question 11

Which of the following is a committee that reviews the procedures of studies done with humans to ensure that the benefits of the study substantially outweigh any risks to the participants and that the risks to the participants have been minimized?

Accepted Answer

The committee described in the question is commonly referred to as an Institutional Review Board (IRB), also sometimes called a Human Research Ethics Committee (HREC) or Human Subjects Committee. Therefore, choice B, "A human participants committee," is the best choice.

Question 12

A researcher is interested in the relationship between depression and the loss of a loved one. The individuals of interest are bereaved adults and non-bereaved adults. The variables in this study receive no manipulation, and depression is measured in both sets of adults. This is an example of:

Accepted Answer

This study involves comparing two groups of individuals (bereaved adults and non-bereaved adults) on a measured variable (depression), with no manipulation of variables. Therefore, it is a group comparison study. It is not naturalistic observation because the researcher is not simply observing behavior in its natural setting. It is not an experimental study because there is no manipulation of variables. It is not a case study because it involves comparing two groups of individuals, not just one individual.

Question 13

If a researcher found that the more cooperative children were with their parents, the more they cooperated with their teachers. This would be an example of a _____ correlation.

Accepted Answer

The statement explicitly mentions that there is a positive correlation between the level of cooperation a child has with their parent and the level of cooperation they have with their teachers. Therefore, the best answer is D, positive correlation.

Question 14

When the conclusions drawn from a study are applicable to other individuals or groups, this is known as _____.

Accepted Answer

Generalizability refers to the extent to which the conclusions of a study can be applied to a larger population beyond the individual or group studied. Rationalization refers to justifying certain behaviors or beliefs. Operationalization refers to defining how a variable will be measured or manipulated in a study. Conceptualization refers to defining a concept or construct being studied.

Question 15

The type of study that observes people on two or more occasions over time is a _____ study.

Accepted Answer

A longitudinal study observes the same participants repeatedly over time, often assessing changes in behavior or health status. In contrast, a cross-sectional study analyzes data collected at a specific point in time, and a case study is an in-depth analysis of one individual or group. A correlation-coefficient study focuses on the strength and direction of the relationship between two variables, rather than observing changes over time.

Question 16

Brad wants to study the relationship between anxiety and registration events in first-semester freshman. Most likely, Brad will use a(n) _____.

Accepted Answer

A cross-sectional type of study would be the best choice for Brad to examine the relationship between anxiety and registration events in first-semester freshmen. This type of study involves collecting data at a single point in time from a group of individuals with the same characteristics or experiences, in this case, first-semester freshmen who have gone through registration events. Brad can then analyze the data to determine if there is a correlation between anxiety levels and registration events. A group comparison study compares different groups of individuals, an experimental design manipulates variables to determine cause and effect relationships, and a sequential study follows individuals over time to observe changes.

Question 17

Dr. Samuel wants to study the relationship between test anxiety and age in younger children. His participants are 3^rd-, 4^th-, and 5^th-graders who will be studied over a three-year period. This is an example of a(n):

Accepted Answer

This is a longitudinal study because the same group of participants (3rd, 4th, and 5th graders) will be studied over a period of three years to see the relationship between test anxiety and age. Cross-sectional studies involve comparing different groups at one point in time, experimental studies involve manipulating variables to test cause-and-effect relationships, and case studies involve in-depth analysis of a single individual or case.

Question 18

A _____ between stress and depression would mean that people who report more stressors have higher levels of depression, and a _____ would mean that people who report more stressors actually have lower levels of depression.

Accepted Answer

A positive correlation means that as the value of one variable increases, the value of the other variable also increases. In this case, as the number of stressors reported by an individual increases, their level of depression also increases, which is a positive correlation.

A negative correlation means that as the value of one variable increases, the value of the other variable decreases. This scenario is not likely for stress and depression since both variables are related to negative affect. Therefore, Options A, B, and C are incorrect.

However, a reverse or negative correlation could be possible in a scenario where stressors lead to increased resilience and coping mechanisms, which eventually result in lower levels of depression. But since this is not mentioned in the question, Option D is the best choice for the given scenario.

Question 19

The correlation coefficient is:

Accepted Answer

The correlation coefficient is a statistical measure that represents the relationship between variables. It ranges from -1 to +1 and indicates the strength and direction of the relationship between two variables.

Question 20

Explaining the purpose of the research and answering participants' questions at the end of the study is known as:

Accepted Answer

Debriefing is the process of explaining the purpose of the research and answering any questions that participants may have at the end of the study. This is important to ensure that participants fully understand the study and are not left with any confusion or unaddressed concerns. Options A, B, and D are not accurate terms for this process.
