Increase the number of actions on the game

-Essential skill for enriching the vocabulary-

-Case Study –

Starting from the study by Joseph S. Lalli we replicated the model of intervention and obtained, besides a larger variety of actions with an object and an increase in the spontaneous commentary. Although the procedure aimed at expanding the number of actions on the same object, placing stereotyped behaviors into extinction; there was also an increase in vocal behavior.

Based on this study and the data we obtained by replicating it, we can come to the conclusion that improving the quality of the game contributes substantially to the quality of the vocal behavior.

Our presentation will cover the description of the work environment, the working methods, the materials used, and the results obtained.
