An evaluation of a high-probability instructional sequence to increase acceptance of Food and decrease inappropriate behavior in children with pediatric feeding disorders.
Research in Developmental Disabilities, 2005Co-Authors: Meeta R Patel, Cathleen C Piazza, Gregory K Reed, Melanie Hope Bachmeyer, Stacy A Layer, Ryan S. PabicoAbstract:We evaluated the effects of escape extinction with and without a high-probability (high-p) instructional sequence on Food acceptance and inappropriate behavior for children diagnosed with feeding problems. The high-p sequence consisted of three presentations of a response that was similar topographically (i.e., presentations of an empty nuk®, liquid on a spoon, and a preferred liquid on a spoon) to the low-p response (i.e., presentation of a nuk with Food, liquid from a cup, and presentation of a Nonpreferred Food). Acceptance of Food increased in the presence and not the absence of the high-p sequence during initial withdrawals for two of the three children. In addition, the high-p sequence plus escape extinction was associated with reduced levels of inappropriate behavior relative to escape extinction alone for two children. Data are discussed in relation to behavioral momentum, motivating operations, and the relative contributions of the high-p instructional sequence and escape extinction in the treatment of feeding problems.

An evaluation of simultaneous and sequential presentation of preferred and Nonpreferred Food to treat Food selectivity.
Journal of applied behavior analysis, 2002Co-Authors: Cathleen C Piazza, Meeta R Patel, Christine M. Santana, Han Leong Goh, Michael D. Delia, Blake M. LancasterAbstract:In the current investigation, we compared two methods of Food presentation (simultaneous vs. sequential) to increase consumption of Nonpreferred Food for 3 children with Food selectivity. In the simultaneous condition, preferred Foods were presented at the same time as Nonpreferred Food (e.g., a piece of broccoli was presented on a chip). In the sequential condition, acceptance of the Nonpreferred Food resulted in presentation of the preferred Food. Increases in consumption occurred immediately during the simultaneous condition for 2 of the 3 participants. For 1 participant, increases in consumption occurred in the simultaneous condition relative to the sequential condition, but only after physical guidance and re-presentation were added to treatment. Finally, consumption increased for 1 participant in the sequential condition, but only after several sessions. These results are discussed in terms of possible mechanisms that may alter preferences for Food (i.e., establishing operations, flavor-flavor conditioning).

effects of Food preferences on token exchange and behavioural responses to inequality in tufted capuchin monkeys cebus apella
Animal Behaviour, 2007Co-Authors: M B Fontenot, S L Watson, Kathleen A Roberts, R W MillerAbstract:We examined the extent to which female capuchin monkeys show an ‘aversion to inequitable work effort’ by providing the monkeys with the opportunity to engage in token exchange tasks to earn either a preferred (grape) or Nonpreferred (oat cereal) Food item. In experiment 1, monkeys were paired with partners such that both were required to exchange a token (work effort) for either a preferred or Nonpreferred Food reward. The subject's exchange behaviour was then compared to conditions in which the partner received the Food reward for no work effort. We found no evidence that differential work effort influenced the percentage of incomplete exchanges. Furthermore, capuchins completed exchanges more rapidly for the preferred Food item, regardless of the work effort of the partner. In experiment 2, we evaluated, in the absence of differential work effort, behavioural responses of monkeys to receipt of a preferred or Nonpreferred Food in conditions where their partner received either the same or different Food. These conditions were compared to control conditions where either the same or different Food was placed in an adjacent empty cage. Capuchins were less likely to accept Nonpreferred Food and consumed it more slowly than preferred Food. We found no evidence that the presence of a partner influenced acceptance or consumption of the Nonpreferred Food under inequitable conditions. Overall, we found no indication that capuchins are able to evaluate either the relative work effort of a partner or the inequity of a Food reward and are thus unlikely to possess an ‘aversion to inequity’.
