Three patients with advanced breast cancer are described who developed lymphangitic pulmonary metastases with normal chest x-rays and abnormal perfusion lung scans. The abnormal lung scans can probably be attributed to embolization of the pulmonary v

Human altruistic responding (called give responding), which delivered a reinforcer to someone other than the responder, was compared to responding where the responder was the recipient of the reinforcer (called earn responding). The same type of resp

Si~mmasy.-Two procedures were evaluated in terms of their ability to modify the slowed responding of schizophrenics under an FR 40 schedule. FR 40 response rares increased when schizophrenics were instructed to earn a minimum number of reinforcemencs

In a series of experiments, it was shown that various histories of response omission can have suppressive effects on the operant responding of humans under a fixed-ratio (FR) schedule of reinforcement. Response omission was produced during these hist

Actual occurrences of cost (point loss per response) were compared with verbal instructions to imagine occurrences of cost in terms of their relative suppression of inter-reinforcement responding under an FI 10 sec. schedule of point reinforcements.

Human behavior may persist despite the fact that it produces unnecessary (preventable) loss of positive reinforcement. Data are presented which demonstrate that such persistence may be due to (1) a history of conditioning which fails to provide indiv

Inter-subject differences in response rates under free-operant avoidance and escape schedules are commonly obtained from humans. Data are presented which demonstrate that such differences can be controlled experimentally by giving subjects different
