Comparison of the septal lesion effects on visual and spatial discriminations in rats
Abstract:
Postoperative performance in acquisition and reversal learning of septal rats was investigated and compared with control rats in three experiments. Experiment I involved a simultaneous black-white discrimination task. The number of errors in normal and septal rats was similar in acquisition and reversal learning. Both septal and normal rats manifested directional response sets. Experiment II examined a position habit discrimination. Acquisition was similar in septal and normal rats, while reversal learning was impaired in septal rats. Experiment III, which investigated a position habit discrimination with available irrelevant visual stimuli indicated that both acquisition and reversal learning were impaired in operated animals. Results suggested that septal rats utilize response produced cues to control their behavior, but the enhanced orienting response to the visual stimuli interferes with the proprioceptive stimuli.

Generalization, Discrimination, and Extinction
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
