Deprivation is an important operation to establish the value of the reinforcer and, consequently, affect the frequency of a class of operant responses. Since his firsts studies, Skinner dealt with deprivation from the concept of drive. After him, many authors in behavior analysis gave an important role to this phenomenon in their work. Despite that, it seems that deprivation especially water and food deprivation are discussed in this dissertation has been neglected by behavior analysts. It has been found only 193 articles about this subject in behavior analysis or in experimental psychology over a period of 80 years. The subject also seems to be marginal in terms of research programs. There are many complex questions regarding the effects of, eg., deprivation history, different deprivation procedures and interactions among deprivations. Deprivation has been used as a mere experimental procedure to establish certain reinforcers, without caring to other possible effects of this procedure. Many authors merely report, in the method, the value of the percentage of free feeding body weight, under which the subject was kept. The studies that have been analyzed showed that some care must be taken when studying experimentally deprivation or when using it as a procedure. For example, it is necessary to control the deprivation history, to choose the best the procedure (amount or time restriction) and the criteria used (eg., percentage of free feeding body weight), to think about the ethical questions involved, etc
