In John B. Calhoun's early crowding experiments, rats were supplied with everything they needed—except space. The result was population boom, followed by such severe psychological disruption that the animals died off to extinction. The take-home message was that crowding resulted in pathological behavior—in rats and by extension in humans. For those pessimistic about Earth's "carrying capacity," the macabre spectacle of this "behavioral sink" was a compelling symbol of the problems awaiting… Expand

It is shown how environmental psychologists were inspired by the fashion around the claimed relevance of human territoriality for the large-scale social problems, such as aggression, war and population growth, in the latter part of the 1960s. Expand

  • 2011
Experimental organisms are systems that have been engineered and modified to enable the controlled investigation of specific phenomena, yet at the same time they remain largely mysterious products of millennia of evolution, whose behaviours, structures, and physiology are for the most part still relatively ill-understood by scientists.

Behavioral methods for the study of the Ras-ERK pathway in memory formation and consolidation: passive avoidance and novel object recognition tests.
This chapter describes two main one-trial behavioral tests commonly used in the field of memory research in order to assess the role of Ras-ERK signalling in long-term memory: passive avoidance and object recognition and the formula of a new index, the recognition index (RI), which quantifies the ability of an animal to recognize a same object at different time points.

When rabbits became humans (and humans, rabbits): stability, order, and history in the study of populations
This paper examines several interlinked episodes in the history of “population” as an organizing concept in 20th century science, tracking the transfer of facts from rabbit populations to human populations (and vice versa) through economics, infectious disease modelling, and macro-histories. Expand
