Preference Testing
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 preference and/or testing:
“Among all the world’s races, some obscure Bedouin tribes possibly apart, Americans are the most prone to misinformation. This is not the consequence of any special preference for mendacity, although at the higher levels of their public administration that tendency is impressive. It is rather that so much of what they themselves believe is wrong.”
—John Kenneth Galbraith (b. 1908)
“Bourbon’s the only drink. You can take all that champagne stuff and pour it down the English Channel. Well, why wait 80 years before you can drink the stuff? Great vineyards, huge barrels aging forever, poor little old monks running around testing it, just so some woman in Tulsa, Oklahoma can say it tickles her nose.”
—John Michael Hayes (b.1919)
