Unit 1 Review- AP Psych

Define a double blind procedure:

• A statistical procedure that identifies common factors among groups of items

• An experimental procedure in which both the research participants and the research staff are ignorant about whether the research participants have received the treatment or a placebo.

• Any effect on behavior caused by the placebo, which the recipient assumes is an active agent, given to the control group in an experiment.

• A statement of the procedures used to define research variables.

The arithmetic average of a distribution, obtaining by adding the scores and then dividing by the number of score is the

• median

• mean

• mode

• dependent variable

A computed measure of how much scores vary around the mean score dependent on the range and square root of total scores.

• inferential statistic

• standard deviation

• descriptive research

• average

Assigning participants to experimental and control conditions by chance, minimizing preexisting differences between those assigned to the different groups.

• random sampling

• double blind procedure

• random assignment

• random mugging

In an experiment, the group that is not exposed to the treatment being studied.

• experiemental group

• random sampling

• control group

• confounding variable

The psychoanalytic approach in psychology believes

• all of our behavior is learned.

• people are capable of self-actualization

• much of our behavior stems from unconscious wants and desires.

• memory formation depends on sensory input.

1.  By seeking to measure "atoms of the mind" who established the first psychology laboratory?

• Sigmund Freud
• John B Watson
• Wilhelm Wundt
• G Stanley Hall

A humanistic psychologist working with some poets might ask which of the following questions?

• How can we get them to reach their highest potential?
• How did their childhood experience impact their current writings?
• How do society's attitudes affect their writing topics?
• How do their brains differ from those of other successful people?

Dr. Kleiman gives an exam where most of the students receive failing grades and only a few students receive high scores.  When the exam scores are plotted, the distribution will be

• positively skewed
• negatively skewed
• symmetrical
• impossible to predict without more information

When scores are "bunched up"in the center of a distribution, the

• mean will be relatively low

• standard deviation will be relatively low

• correlation coefficiaent will be a negative number

• standard deviation will be relatively high
