Abstract in Portuguese
Modelos experimentais do transtorno obsessivo compulsivo (TOC) com humanos mostram que uma forma de evocar comportamentos de checagem é apresentar instruções que especificam consequências aversivas para o comportamento inefetivo na execução de tarefas. Atualmente há na área somente um estudo experimental com delineamento de sujeito único. Os presentes dois experimentos com 16 participantes verbalmente habilidosos tiveram o objetivo de testar se instruções com especificação de consequência aversiva ou apetitiva poderiam ter o efeito de produzir respostas de checagem. Em um restaurante experimental, as instruções foram apresentadas durante uma tarefa de separação de sementes misturadas. No Experimento 1, cinco de oito participantes apresentaram maiores porcentagens de checagens sob especificação de consequência aversiva. No Experimento 2, sete de oito participantes apresentaram maiores porcentagens sob especificação de consequência apetitiva. Concluiu-se que determinadas instruções alteraram a função discriminativa e/ou motivadora dos estímulos envolvidos na tarefa experimental. Sugere-se que o presente delineamento pode permitir a formulação de análises funcionais do fenômeno comportamental normalmente envolvido em alguns casos de TOC

Abstract in English
Experimental models of obsessive compulsive disorder (OCD) with humans show that a way to evoke checking behaviors is to provide instructions that specify aversive consequences for behavior ineffective in performing tasks. Currently there is only one experimental study with a single subject design in this area. The present study presents two experiments with 16 verbally skilled participants tested whether instructions specifying the appetitive or aversive consequence could have the effect of producing checking behaviors. In an experimental restaurant, the instructions were presented during a task of separation of mixed seeds. In Experiment 1, five of eight participants showed higher percentages of checks under specification of aversive consequence. In Experiment 2, seven of eight participants had higher percentages under specification of appetitive consequence. It was concluded that certain instructions alter the discriminative and motivate function of the stimuli involved in experimental task. It is suggested that this design may allow the formulation of functional analysis of behavioral phenomenon normally involved in some cases of OCD
