- operational definition
- independent variable
- a a measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. The ____ coefficient is the mathematical expression of the relationship, ranging from -1 to +1
- b all the cases in a group, from which samples may be drawn for a study
- c a statement of the procedures used to define research variables
- d the experimental factor that is manipulated; the variable whose effect is being studied
- e chemical messengers that traverse the synaptic gaps between neurons. When released by the sending neuron, _____ travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
5 Multiple Choice Questions
- the perception of a relationship where none exists
- An experimental procedure in which both the research participant and the research staff are ignorant about whether the participants have received the treatment or the placebo
- a neural impulse; a brief electrical charge that travels down an axon. the ____ is generated by the movement of positively charged atoms in and out of channels in the axon's membrane
- the most frequently occurring score in a distribution
- repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding extends to other participants and circumstances
5 True/False Questions
threshold → the level of stimulation required to trigger a neural impulse
empiricism → "morphine within"--natural, opiatelike neurotransmitters linked to pain control and pleasure.
standard deviation → a computed measure of how much scores vary around the mean score
natural selection → the condition of an experiment that contrasts with the experimental condition and serves as a comparison for evaluating the effect of the treatment
endorphins → "morphine within"--natural, opiatelike neurotransmitters linked to pain control and pleasure.
