AP Psych Exam Review #1: RESEARCH, BIO, & COGNITION

An observation technique in which one person is studied in depth in the hope of revealing universal principles.

• survey

• experimental study

• case study

• naturalistic study

A sample that fairly represents a population because each member has an equal chance of inclusion.

• random sample

• skewed sample

• biased sample

• sample

A statistical index of the relationship between two things (from -1 to +1).

• apex

• correlation coefficient

• standard deviation

• variance

Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active agent.

• learned helplessness

• placebo effect

• social exchange theory

• comparative deprivation

In an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable.

• placebo group

• control group

• correlational group

• experimental group

A computed measure of how much scores vary around the mean score.

• mean

• median

• standard deviation

• mode

The most frequently occurring score(s) in a distribution.

• Mean

• Mode

• Average

• Standard Deviation

a nerve cell; the basic building block of the nervous system.

• neuron

• myelin sheath

• dendrites

• axon

a neural impulse; a brief electrical charge that travels down a neuron.

• cell connection

• electrical charge

• refractory period

• action potential

Chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, these chemicals travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.

• hormones

• neurotransmitters

• agonists

• antagonists
