Exam 2: How Psychologists Do Research

Dr. Myers found that students in her class who scored 80% or better on the mid-term exam were likely to score 70% or better on the final exam. Students who scored below 60% on the midterm, however, were likely to end up failing the final exam. These test results suggest:

An operational definition is:

Famed sex researcher Alfred Kinsey found that more truthful responses were elicited when he phrased a question in which of the following ways?

Harvey is being assessed in order to measure his beliefs and feelings regarding the next election. It is most likely that the assessment instrument will be a/an:

It is quite likely that the more classes students miss, the lower their test grades tend to be. This relationship illustrates a/an:

The Canadian Psychological Association (CPA) suggests that all its members develop strong ethical codes for their research projects.

Which of the following statements is NOT true?

In the control condition, subjects are treated exactly as they are in the experimental condition, except that they are not exposed to the same treatment of the independent variable.

When two variables are correlated, one variable may or may not be causing the other.

Is there a critical period for language? When the sad story of Genie was broadcast on television, many people wondered what the future would hold for a 13-year-old girl who had survived on minimal physical care. What did psychologists learn about language acquisition through their efforts to teach language to Genie? In what ways does Genie's story illustrate some drawbacks to the case study method?

Inferential statistics are statistical procedures that organize and summarize research data.

The strongest relationship, as indicted by these correlation coefficients, is:

All of the following are accurate statements regarding random assignment EXCEPT:

Ken is given a vocational-interest test and then takes a similar test a week later. The psychologist is measuring the ________ of the test.

One shortcoming of laboratory observation is that the presence of researchers and special equipment may cause subjects to behave differently than they would in their usual surroundings.

Case studies proved that autism in children was caused by rejecting, cold, "refrigerator" mothers.

If we have enough participants in our study and use a random assignment procedure, then individual characteristics that could possibly affect the results are likely to be roughly balanced in the two groups.

Professor Turner wants to know if physiological changes occur when people watch violent movies. The most appropriate method to study this would be:

Unintended changes in subjects' behaviour due to cues inadvertently given by the experimenter are called:

An advantage of an experiment is that:
