| Abstract: The matching-to-sample procedure is used to study the relations involved in "reading" and, more specifically, examine the emergence of new conditional relations from that directly trained. However for a proficient reading it is necessary to read under control of smaller units than the word, so that the reading behavior under control by minimal units could emerge. The majority of researches in this area have been carried out with training and recombinative testing of the whole words. Reading behavior under control by the minimal units in these studies generally appears after training at least three sets of words. The objective of this study was to investigate the possibility of an increase in speed of acquisition of control by smaller units in recombinative reading through the direct training of a repertoire of four monosyllabic words. In the first experiment, four children participated (aged between 3 and 5 years ). The original’s experimental stimuli were NO, PE, PA and LU and the derived stimuli were LUPA, PANO, PAPA and LULU. The results showed that all four participants showed no emergence of recombinative reading. In the second experiment the original's stimuli was change to BO, BA, LA and LO, and also the derived stimuli to BABO, BOBA, LALO and LOLA. Three children that participated on the previous experiment were involved. As a result, two participants showed recombinative reading and the variability in performance of these participants was smaller than in the previous studies. The partition of the stimulus was considered an important variable for the functional independence of syllables and subsequent emergence of recombinative reading. Thus, the monosyllabic training was effective to increase the speed of acquisition of control by smaller units in recombinative reading. |

| Abstract: This paper offers an experimental analysis of changes in perception. In doing so, the relative flexibility of a person’s perception of color as a product of interacting with other colors will be demonstrated through a matching procedure in a training and testing methodology. The analysis focuses on how setting factors (i.e. stimuli immediately preceding a test stimulus) come to affect a person’s behavior with respect to the test stimulus. We argue that what is present for a participant in interaction with a stimulus is a history of past interactions with other stimuli. Data obtained from this study will be discussed as well as conceptual and methodological contributions of this investigation. |
