Nesting material as a reinforcer for operant behavior in the rat

Rats will readily work for the acquisition of nesting material. Paper strips serves as an adequate reinforcer. .. Prior to parturiation, only a small daily nest was built and barpressing occurred only in the dark part of the lighting cycle....

Interaction of environmental enrichment and genotype

Assessed the effects of exposure to an enriched environment, from birth-38 days of age, using 3 behavioral tests: open field, exploration, and running wheels. 144 inbred mice from 3 strains (A/J, C3H/HeJ, and C57BL/10J) were used as Ss in a...

Hair-nibbling and whisker-trimming as indicators of social hierarchy in mice

Barbering is a common abnormal behavior in laboratory mice. Alopecia and loss of facial hair, as well as loss of vibrissae, seem to be a physical indiaction of social dominance.

The effects of cage environment upon avoidance responding in aged rats

The beneficial effects of environmental enrichment are not restricted to a brief cricial period in development. Positive effects occur also in rats aged 300 days when first placed in an enriched environment.
