Epstein, 1994; S. Epstein, A. Lipson, C. Holstein, & E. Huh, 1992; S. Epstein, R. Pacini, V. Denes-Raj, & H. Meier, 1996; L. A. Kirkpatrick & S. Epstein,(More)
Detection of water and social play reinforcers by a place conditioning method based on instrumental conditioning was investigated in rats and compared to detection by conditioned place preference, a method currently used primarily to measure drug reinforcement. Operant place conditioning measures of reinforcement were choices between the reward and(More)
Each of four doses of intravenous morphine and four of intravenous heroin was tested for reinforcing efficacy, and comparisons were made among the four morphine doses, among the four heroin doses, and between morphine and heroin. Rats with venous catheters performed one daily forced run for 75 s to one of the two compartments of a spatial choice apparatus,(More)
A new place conditioning procedure for assessing drug reinforcement, based on drug administration following chamber entry, was examined in rats and compared to conditioned place preference (which is based on chamber exposure of drugged animals). Besides relative time subsequently spent in the morphine chamber, choices between the drug and nondrug chambers(More)
A recent study found a high rate of CMV excretion among children in a group day care center (DCC) enrolling primarily children from middle income families, suggesting that the increasing use of group DC in this country could change the epidemiology of CMV. We studied 5 DCCs serving children of diverse backgrounds and examined CMV infection rates (IR) (viral(More)
