The effects of antecedent and consequent events on the verbal behavior of three institutionalized mentally retarded adolescents were examined. Verbal statements, related to current national and international events, were recorded after exposures to television news programs. The study examined the accuracy of verbalizations as a function of: (1) exposures to television news presentations in massed (i.e., viewing the entire news program before an opportunity to describe it) versus distributed from (i.e., viewing each news item separately with each followed by an opportunity to describe it), and (2) contingent tokens and social praise for correct verbal responses (i.e., statements corresponding to news items presented). Both the temporal distribution of news presentations and the reinforcement procedures improved the accuracy of verbal statements emitted by the subjects.
本文考察了先行事件和后续事件对 3 名机构内智障青少年言语行为的影响。在观看电视新闻节目后，记录了与当前国内外事件相关的言语陈述。研究考察了言语准确性作为以下因素的函数：（1）集中（即在有机会描述之前观看整个新闻节目）与分散（即分别观看每个新闻项目，每个项目后都有机会描述）暴露于电视新闻节目；（2）对正确言语反应的定比代币和社会赞扬（即与呈现的新闻项目相对应的陈述）。新闻呈现的时间分布和强化程序都提高了被试者言语陈述的准确性。
