Document Summary

Research design: correlational, statistical methods are used to asses and describe the amount and type of relationship between two variables of interest, advantage: can be used to answer questions about relationships that cannot be clarified by other research methods, limitations: cant conclude that it is a cause effect relationship, experimental, subjects are confronted with specific stimuli under precisely controlled conditions, researchers manipulate a particular set of condition and then observe the effect on behavior, advantages: provides opportunity to make a cause effect relationship conclusion. Neural transmission: resting potential (neuron is polarized, negative inside, 70 millivolts, na+ outside/ cl inside, graded potential, disturbance when an impulse is received from another neuron, axon hillock; determines whether or not a graded potential is sufficient to bring the axon to its threshold level, action potential (axon is depolarized, membrane changes permeability to na+ enters cell, positive inside, 55 millivolts.
