PANOSSO, Mariana Gomide  and  SOUZA, Silvia Regina de. Stimulus equivalence: Effects of a board game about food choices. Acta comport. [online]. 2014, vol.22, n.3, pp. 315-333. ISSN 0188-8145.

This research has investigated the effect of a board game use on the formation of equivalence classes of stimuli and food choices evaluation through pictures, by children under dietary restrictions. Two children aged seven and eight were the participants in this research. The protocol consisted of six phases: research on eating habits, assessment and food choices pre-tests, intervention / game, MTS learning, testing of the emergent properties / post-test. Initially, participants indicated on a sheet of paper choices and preferences for foods (pre-test). During intervention, eight game sessions were conducted, which aimed at teaching the relations AB and AC. Each class of stimuli consisted of three images: A-supermarket baskets, B - food groups and C - hands indicating positive. Subsequently, the relations AA, BB, CC, BA, CA, CB and BC (Test of emerging properties) were tested, followed by the post-test. There was formation of equivalence classes. For one of the participants, changes in food choice evaluation have been reported and, according to their legal guardians, both participants consumed food items they would not eat before the intervention. We discuss the variables presented in the game that may have contributed to participants' consumption of new food items.
