Comparisons between this new problem set and the Rabinovitch-Rosvold (1951) closed-field tests are presented with respect to difficulty, internal consistency, and test-retest reliability.Abstract:
An automated “intelligence” test for rats is described. Supporting data indicate that this maze-problem series is sensitive to hypothyroidism-induced learning deficit and sex differences. Comparisons between this new problem set and the Rabinovitch-Rosvold (1951) closed-field tests are presented with respect to difficulty, internal consistency, and test-retest reliability.read more

Gonadal hormones and sex differences in nonreproductive behaviors in rodents: Organizational and activational influences
TL;DR: Sexual dimorphic responses in the rat are often not similarly differentiated in the hamster, the gerbil, or the mouse; and major differences exist among rodent species in hormonal effects on such responses, suggesting whether sex differences in certain laboratory learning tasks have any adaptive significance.
Journal ArticleDOI
Organizational effects of early gonadal secretions on sexual differentiation in spatial memory.
TL;DR: The data suggest that early exposure to gonadal steroids (probably estradiol) improves acquisition of spatial tasks by reorganizing and simplifying associational-perceptual processes that guide spatial ability.

Meta-analysis of sex differences in rodent models of learning and memory: a review of behavioral and biological data
TL;DR: The reliability of male advantages in spatial working and reference memory for rats across strains, protocols, ages and rearing environments is established and an important species dichotomy between rats and mice should be considered when transitioning from rat to mouse models.
Journal ArticleDOI
The organizational effects of gonadal steroids on sexually dimorphic spatial ability
TL;DR: The studies described in this review suggest that gonadal steroids, probably the testosterone metabolite estradiol, cause organizational effects during perinatal development which have multiple effects on the associational-perceptual-motor biases that guide visuospatial navigation.

Sex differences in hippocampal long-term potentiation (LTP) and Pavlovian fear conditioning in rats: positive correlation between LTP and contextual learning
TL;DR: A positive correlation between the magnitude of hippocampal LTP and a form of learning that depends on the hippocampus is revealed and a neural basis for sex differences in hippocampus-dependent learning tasks is suggested.

Intellectual Deficit Associated with Transplacentally Induced Microcephaly in the Rat
TL;DR: Fischer rats injected with methylazoxymethanol late in pregnancy produce young with considerably reduced cerebral hemispheres, and as adults these animals make many more errors in the Hebb-Williams maze than do control animals.

Cretinism in rats: enduring behavioral deficit induced by tricyanoaminopropene.
TL;DR: Exposure to tricyanoaminopropene before and after birth, at doses sufficient to produce anatomicalcretinism, apparently induces an enduring behavioral deficit which is similar to that of neonatal thyroidectomy-induced cretinism in rats and which parallels the mental retardation associated with human cretinists.

The rat, rabbit and cat in the hebb-williams closed field test of animal intelligence
TL;DR: Eight rats, ten rabbits and eight cats were tested in a form of the Hebb-Williams Closed Field Test, and two scoring methods, “error score” and “excess square entry score,” were employed.
