Research Methods in Psychology

Method of intense study of just one individual:

• Naturalistic Observation

• Experimental Study

• Case Study

• Survey

Dement and Kleitman (sleep and dreams) utilized what research method?

• Field experiment

• Case study

• Lab experiment

• Lab experiment with varying research methods for each aim

In an experiment, the _________________ variable is tested by the researcher to observe its effect(s) on the _________________ variable.

• independent; dependent

• first; second

• dependent; independent

• control; results

A type of observation conducted in the participants' normal environment without interference from the researchers.

• Controlled observation

• Naturalistic observation

This is a method of research where an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable).

• Experiments
• Case Study
• Survey
• Observational
• Correlational

The advantage of this descriptive method of research is that it creates an immense amount of data to be gathered quickly and inexpensively.

• Survey
• Observational
• Correlational
• Experiments
• Case Study

In experimental studies which group receives nothing? In other words, they do not get the variable that is under study.

• Experimental group

• Control group

The research method/design employed by Piliavin et al. (subway Samaritan) was...

• Field experiment with independent measures design

• Field experiment with repeated measures design

• Controlled observations with independent measures design

• None of the above

What kind of relationship is this?

• Positive Correlation

• Negative Correlation

• No Relationship

In a study, injections of saline solution (which contains no chemicals) were shown to be quite effective for relieving pain. This is an example of:

• experimenter effect

• placebo effect

• experimental effect

• order effect
