The distribution of response latencies and the percentage performance curve of a classical conditioning group, by comparison with a control group, indicated that the extension of the nictitating membrane elicited by a puff of air to the cornea was successfully conditioned to a previously neutral stimulus.

qt t is unfortunate that in social survey work terms such as 1 reliability and validity, which are dichotomous in their classical origins (i.e., something is or is not reliable; something is or is not valid), take on variable meanings. And it is the variable meaning that is intended through our use of the terms when applied to the results of our comparison between two survey methodologies. We contend, based on the data reported in the article, that the key informant estimates of certain health-risk behavioral factors were &dquo;more valid&dquo; than estimates provided by the telephone survey technique, and that contention is stated with a number of caveats (e.g., given the population and the distribution of that population in New Mexico, etc.). There are, of course, other social survey methods that produce different estimates, and those can be used for comparison purposes (notes 4 and 6 made reference to such comparisons). Regarding seat belt use, mentioned in the preceding comments, an observational study conducted by the New Mexico Department of Transportation during the same period of time that the two surveys presented in our article were conducted resulted in the conclusion that only 11% of New Mexico's residents wear a seat belt. That obviously represents only a fraction of the estimates made by either the telephone or the key informant surveys. Because wearing a seat belt is not a statutory requirement in New Mexico, the &dquo;number of charges laid for not wearing seat belts&dquo; is not available, but records are kept by the State Police in all cases of

Ingestion in rats given limited daily access to water of 12 degrees , 24 degrees , and 37 degrees C is a positive function of water temperature, even though ingestion of warm water decreases blood osmotic concentration faster than cold water. The paradox suggests that temperature-dependent gastric factors and water-transport factors determine stomach distention cues of thirst satiation.

A comparison of the percentage-performance curve of a classical conditioning group with those of three control groups provided unequivocal evidence of successful conditioning of the retractor bulbi response to an auditory conditioned stimulus.
