One-way characteristic performance of rats under two-way signaled avoidance conditions

In Experiment 1, the conflict in a two-way active avoidance was reduced by allowing rats to avoid one of two levels of shock by running onto a safe platform which covered one half of the grid floor. Performance characteristics of one-way avoidance were obtained regardless of the shock intensity. Groups with no platform showed poor performance. Experiment 2 suggested that the facilitatory effect of the platforms was not due to the cue associated with platform removal. These results suggest that (a) rats can quickly learn to enter a spatially aversive location, (b) fast avoidance learning may be obtained in a two-way setting, and (c) rats seem capable of selective association of environmental and aversive stimuli.     

Civic Education and the Good

It is argued that children need to learn about civic issues intheir education because certain virtues are required for a decently organisedsociety. It is also argued that the school has wide obligations to educate theyoung in civics because it is in their best interests. This is not seen asan encroachment on the privacy of the individual. It is explained that theschool has an obligation to impart knowledge to the young.     

Strengthening scientific verbal behavior: an experimental comparison of progressively prompted and unprompted programmed instruction and prose tutorials

Web-based software was used to deliver and record the effects of programmed instruction that progressively added formal prompts until attempts were successful, programmed instruction with one attempt, and prose tutorials. Error-contingent progressive prompting took significantly longer than programmed instruction and prose. Both forms of programmed instruction substantially increased the appropriate use of behavioral vocabulary during subsequent interpretive essays. These behavioral gains extended to a different setting, suggesting that more was being learned than simply how to answer programmed tutorial frames correctly.     

An efficient one- and two-way avoidance apparatus capable of producing identical one- and two-way avoidance performance

A platformed one- and two-way avoidance apparatus is described in which the need for handling the subjects in the one-way task is eliminated and the two-way task is very quickly learned. The acquisition curves obtained for these two tasks are indistinguishable.
