Previous research findings on the interaction between drugs and microwave radiation were extended to chlorpromazine and to diazepam. The drugs were combined with a 1 mW/cm2 pulsed microwave field (2.8 GHz) and effects were measured on a fixed interval (FI 1) schedule of food reinforcement with rats. Dose-effect functions with and without sham irradiation(More)
The acute effects of microwave exposure on a repeated acquisition baseline were investigated in three rats. Each session the animals acquired a different four-member response sequence. Each of the first three correct responses advanced the sequence to the next member, and the fourth correct response produced food reinforcement. Incorrect responses produced(More)
The effects of pulsed-(PW) and continuous-wave (CW) 2.8-GHz microwaves were compared on the performance of rodents maintained by a temporally defined schedule of positive reinforcement. The schedule involved food-pellet reinforcement of behavior according to a differential-reinforcement-of-low-rate (DRL) contingency. The rats were independently exposed to(More)
T HIS ARTICLE summarizes information about authoring system technology resulting from a recent review of eighty products. Altemative authoring approaches, such as programming languages, authoring languages, and authoring systems are described. Assumptions underlying authoring system development and use conceming productivity, course quality, and course(More)
A working prototype database of authoring system software was developed as part of a study of authoring software conducted by the National Library of Medicine. The database and development issues ranging from the scope of the database to what information to document are described. The protype demonstrates that records of reasonable integrity can be derived(More)
Breathing elevated environmental pressures of nitrogen and oxygen produced changes in behavior of rats that evidenced an interaction between the two gases. Rates of responding generated by a fixed-interval schedule of reinforcement systematically changed as partial pressures of nitrogen were elevated from 0.8 to 10.4 ATA. Response rates increased above(More)
