Abstract
Reports an experiment with 126 male albino rats, 48 of whom received bilateral septal lesions. A combination of conflicting intrabox and extrabox cues was necessary to produce deficient acquisition of 2-way avoidance responding relative to 1-way responding in normal Ss. Septal lesions impaired 1-way avoidance acquisition by delaying the 1st avoidance response. In 2-way acquisition, the faster acquisition of septal Ss may be attributable either to an inability to inhibit responding or to an inability to utilize certain types of cues. Until the effects of septal lesions upon the ability to process olfactory and spatial information have been determined, disinhibitory interpretations of changes in avoidance responding must be held in question.
