Performance on the hebb-williams maze as related to discrimination and reversal learning in rats
Performance on the Hebb-Williams Maze was studied in relation to visual form discrimination and reversal. Three groups, each of twenty hooded rats, were first tested on the Hebb-Williams Maze and then on discrimination and reversal in a T-maze with either vertical and horizontal black and white stripes or a black circle and triangle against white […]
Spatial memory for food hidden by rats (Rattus norvegicus) on the radial maze: Studies of memory for where, what, and when
Rats (Rattus norvegicus) were allowed to hide food items on an 8-arm radial maze by carrying the items from the center to boxes at the end of each arm. Retrieval tests given after rats had hidden 4 items showed that they selectively returned to the maze arms where food had been hidden (Experiments 1 and […]
A comparison of four corvid species in a working and reference memory task using a radial maze
Birds were tested in an open-room radial maze with learned spatial locations that varied from trial to trial (working memory) and locations that remained spatially stable (reference memory). Three of the species, the Clark’s nutcracker (Nucifraga columbiana), pinyon jay (Gymnorhinus cyanocephalus), and Western scrub jay (Aphelocoma coerulescens) store food to varying degrees. The other species, […]
Experimental evidence for spatial learning in cuttlefish (Sepia officinalis)
Laboratory mazes were used to study spatial-learning capabilities in cuttlefish (Sepia offcinalis), using escape for reinforcement. In preliminary observations, cuttlefish in an artificial pond moved actively around the environment and appeared to learn about features of their environment. In laboratory experiments, cuttlefish exited a simple alley maze more quickly with experience and retained the learned […]
