The role of differential housing on sucrose-morphine consumption in outbred Wistar rats was investigated in two studies. The results of earlier research, indicating rats housed in a quasinatural colony drank significantly less sucrose-morphine than rats isolated in standard laboratory cages, could not be replicated, as the consumption of sucrose-morphine by the isolated animals in the present two studies was reduced. It is possible that during a colony conversion the supplier inadvertently… Expand

Rat Park: How a rat paradise changed the narrative of addiction
'Rat Park' is the name given to a series of studies undertaken in the late 1970s by Bruce K. Alexander and colleagues. They found that rats housed in enriched environments consumed less morphineExpand
Have we reproduced Rat Park? Conceptual but not direct replication of the protective effects of social and environmental enrichment in addiction
The Rat Park studies are classic experiments in addiction neuroscience, yet they have not been successfully replicated directly and several serious methodological criticisms have been raised.Expand
Confounding factors in toxicity testing.
It is demonstrated that there are differences in the responsiveness of rat stock/strains to chemicals and that lack of consideration of confounding factors yields inappropriate conclusions regarding risk assessment for humans. Expand
A call for replications of addiction research: which studies should we replicate and what constitutes a ‘successful’ replication?
Abstract Several prominent researchers in the problem gambling field have recently called for high-quality replications of existing gambling studies. This call should be extended to the entire fieldExpand
Loops and Recursions in Cognitive Science: Cross-Roads between Methodology and Epistemology
This article addresses the need for cognitive science to loop back and examine its roots and presuppositions, pointing out the three recursive issues: 1.) The observer effect or how observing aExpand

Effect of early and later colony housing on oral ingestion of morphine in rats
Male and female rats were raised from weaning either in isolation or in a large colony. At 65 days of age, half the rats in each environment were moved to the other. At 80 days, the animals wereExpand
Establishment of morphine preference in the rat
Three groups of rats were placed on sucrose morphine and milled rat food for 25 days. Morphine HCl content was.5 mg/ml for all three groups. Sucrose concentrations were 2.5%, 5%, and 10%. In aExpand
Addiction Liability of Albino Rats: Breeding for Quantitative Differences in Morphine Drinking
Two strains of rats that differ in their susceptibility to morphine addiction are produced, and further selection and inbreeding increased the strain difference in the F2 and F3 generations. Expand
Voluntary morphine ingestion, morphine dependence, and recovery from withdrawal signs
The present finding is the first report to show that rats ingest high quantities of sucrose-morphine without premedication or forced hydration procedures. Expand
Effects of chronic naltrexone on amphetamine locomotor activity.
Chronic naltrexone significantly decreased amphetamine activity in old colony animals only under noise conditions, and new colony animals showed a significant attenuation in amphetamine locomotor activity in the absence of noise only. Expand
Within- and Between-Subjects Differences in the Effect of Morphine in Mice
The between-subjects design was more sensitive than the within- subjects design in detecting morphine-induced locomotor and analgesic effects across four repeated injections of morphine. Expand
A drug dispenser to measure individual drinking in rat colonies
An automated device which substantially facilitates the measurement of oral drug consumption by individual rats housed in a colony with a common drinking source is described. Expand

A methamphetamineadone temporary support program is outlined, as an alternative to methadone maintenance of indefinite duration, to strengthen that motivation by providing a nonpunitive environment within which self-help and peer help can operate to alter life style. Expand
