Inescapable Shock Increases Finickiness About Drinking Quinine-Adulterated Water In Rats., Clinton Chapman, Nancy Dess, Thomas Minor

Clinton D Chapman

Conducted 3 studies with 108 male rats to examine the effect of inescapable shock on finickiness, operationally defined as suppressed consumption of quinine-adulterated water. Exposure to a single session of inescapable shock increased finickiness relative to simple restraint or no treatment. The effect of shock on finickiness was replicable, was specific to adulterated water, and persisted for at least 24 hrs. The weak quinine solution rejected by shocked Ss supported a conditioned taste aversion, suggesting that the difference between shocked Ss and controls was not due to the inability of the latter to taste the quinine. It is suggested that …

Norm-Of-Reaction: Definition And Misinterpretation Of Animal Research, Steve A. Platt, Charles A. Sanislow

Charles A. Sanislow, Ph.D.

The development of a phenotype is due to an interaction of the genotype with the environment. Two terms have been used to describe the outcome of this interaction, the norm-of-reaction and the reaction range. The first represents the theoretically limitless distribution of the phenotypes that may be expressed by a given genotype. The reaction range implies an upper and lower limit for phenotype expression possible from a given genotype. A critical distinction between the reaction range and the norm-of-reaction is that the norm-of-reaction is a statement of the conceivable interactions found but does not imply any predictability other than that …
