In the preference testing phase the animal is allowed barrier free access to all compartments of the apparatus. Time spent in each compartment is measured either by the experimenter or by motion detecting software; often the mean seconds per minute spent in each compartment is calculated. Statistical testing is used to determine whether the time difference is large enough, in comparison to the control group, to conclude that conditioned place preference or aversion has occurred. Strength of conditioning is inferred by the magnitude of the difference or in the amount of time taken for the response to show extinction.

Famous quotes containing the words testing and/or preference:
“Traditional scientific method has always been at the very best 20-20 hindsight. Its good for seeing where youve been. Its good for testing the truth of what you think you know, but it cant tell you where you ought to go.”
—Robert M. Pirsig (b. 1928)
“Do not discourage your children from hoarding, if they have a taste to it; whoever lays up his penny rather than part with it for a cake, at least is not the slave of gross appetite; and shows besides a preference always to be esteemed, of the future to the present moment.”
—Samuel Johnson (17091784)
