The availability of various approaches to software-system development for the use of microcomputers in the on-line control of experiments has contributed to the trend. This report describes a software system developed to control conditioned behavior during schedules of reinforcement while simultaneously accumulating behavioral data and physiological (analog) data using a hardware system based on the Radio Shack TRS-80 Model I microcomputer. The software utilizes a high-level interpretive language (Microsoft BASIC), assembly language and compiled BASIC to attain an acceptable execution speed and ease of programming.</p></div>","PeriodicalId":75731,"journal":{"name":"Computer programs in biomedicine","volume":"18 1","pages":"Pages 61-75"},"PeriodicalIF":0.0,"publicationDate":"1984-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0010-468X(84)90024-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17603576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then the experimental protocol requires many repetitive functions with adjustable interval times and magnitudes, which are prepared or dictated by experimental results.

A special language syntax has been developed for: (i) experiment definition; (ii) experiment composition in advance; (iii) real-time control during the actual experiment; and (iv) registration of the actual protocol parameters.
