Question 3

Which statistical analysis is commonly employed to examine differences in means between two independent groups?

Accepted Answer

Independent samples t-test

Answer

Analysis of variance (ANOVA)

Answer

Chi-square test

Answer

Regression analysis

Question 4

Provide an example of a qualitative research method commonly used in cognitive psychology.

Accepted Answer

In-depth interviews allowing for open-ended responses

Answer

Questionnaires with structured response formats

Answer

fMRI scans measuring brain activity patterns

Answer

Observational studies recording behavior in controlled settings

Question 5

Which ethical principle requires researchers to obtain informed consent from participants before involving them in research studies?

Accepted Answer

Autonomy: respecting participants' right to make informed choices about their involvement

Answer

beneficence: maximizing benefits and minimizing harm to participants

Answer

Justice: ensuring fair treatment and equitable distribution of benefits and burdens

Answer

Confidentiality: protecting participants' privacy and maintaining the confidentiality of their data

Question 6

What is a key difference between correlational and experimental research designs?

Accepted Answer

Experimental designs control for variables, while correlational designs do not.

Answer

Correlational designs establish cause-and-effect relationships, while experimental designs do not.

Answer

Correlational designs use qualitative data, while experimental designs use quantitative data.

Answer

Experimental designs are more reliable than correlational designs.

Question 7

What is the primary purpose of replication in scientific research?

Accepted Answer

To validate and confirm previous research findings, increasing their reliability and confidence

Answer

To extend the scope of existing knowledge by exploring new variables or conditions

Answer

To generate novel hypotheses for future research endeavors

Answer

To identify limitations or weaknesses in previous studies, guiding future research directions

Question 8

In experimental research, what principle ensures that participants are randomly assigned to different conditions?

Accepted Answer

Randomization

Answer

Control

Answer

Reliability

Answer

Validity

Question 9

Which non-experimental method involves observing behavior in natural, everyday environments?

Accepted Answer

Naturalistic observation

Answer

Laboratory observation

Answer

Structured interview

Answer

Case study

Question 10

What is the primary limitation of correlational research design?

Accepted Answer

Cannot establish cause-and-effect relationships

Answer

Requires a large number of participants

Answer

Data is difficult to interpret

Answer

Cannot be used to study cognitive processes

Question 11

What is the purpose of conducting a pilot study in research?

Accepted Answer

To refine the research methods and identify potential problems

Answer

To collect data for the full-scale study

Answer

To test the hypothesis of the study

Answer

To ensure that the study is ethical

Question 12

In cognitive psychology, what is a potential drawback of using experimental research methods?

Accepted Answer

Artificiality of the laboratory setting

Answer

High level of control over variables

Answer

Use of objective and measurable data

Question 13

In experimental research, which characteristic ensures that participants have an equal chance of being assigned to any of the experimental conditions?

Accepted Answer

Random assignment

Answer

Controlled variables

Answer

High external validity

Answer

Observational data

Question 14

In a correlational study, a negative correlation suggests that:

Accepted Answer

As one variable increases, the other variable decreases

Answer

As one variable increases, the other variable also increases

Answer

The variables are not related

Answer

The relationship between the variables is positive

Question 15

What is the primary objective of a meta-analysis?

Accepted Answer

To combine and analyze data from multiple studies

Answer

To generate new hypotheses

Answer

To identify flaws in individual studies

Answer

To provide qualitative insights

Question 16

In an experimental design, the variable that is manipulated by the researcher is known as the:

Accepted Answer

Independent variable

Answer

Dependent variable

Answer

Confounding variable

Answer

Extraneous variable

Question 17

When conducting research involving human participants, which ethical principle requires that participants provide informed consent?

Accepted Answer

Informed consent

Answer

Confidentiality

Answer

Protection from harm

Answer

Debriefing

Question 18

Which confound occurs when participants are not randomly assigned to conditions and the researcher does not consider pre-existing differences between the groups?

Accepted Answer

Selection bias

Answer

Experimenter bias

Answer

Demand characteristics

Question 19

What is replicability in research, and why is it crucial for ensuring the reliability and generalizability of research findings?

Accepted Answer

Replicability refers to the ability to reproduce research findings under different conditions or with different participants, demonstrating the reliability of methods and the robustness of findings.

Answer

Replicability is solely important for generalizing findings to different populations, but not for indicating the reliability of research methods.

Answer

Replicability is achieved when different researchers conduct the same study and obtain identical results in every aspect.

Answer

Replicability is not a necessary criterion for high-quality research, and findings can be considered valid even if they cannot be replicated.
