Análise da aquisição de comportamento verbal em uma criança dos dezoito meses aos dois anos de idade

Abstract

The purpose of the present study is to investigate the acquisition of verbal behavior in a longitudinal research with a typical development child from eighteen months of age until two years old, adopting as unit of analysis Skinner´s (1957) verbal operants. The aim of the present work is to analyze verbal responses emitted by the child and the caretakers in a natural setting in terms of verbal operants and try to identify relations between the emission of operants by caretakers and the child, investigating possible interaction patterns in the acquisition of verbal behavior. Thirty four sessions of fifteen minutes of duration were registered per week and then transcript. Data were analyzed based upon categories created from Skinner´s verbal operants (1957). Results show a rapidly increase in the emission of tact, mand, echoic and intraverbal categories of the participant after twenty months of age. This increase also happened simultaneously in the emission of the same categories of the caretaker. The most emitted category of the child was the tacts, while the most emitted category by the caretaker was the mands.

Learning by Playing: Echo and Tact in Expanding the Verbal Repertoire of Infants

“…This combination of factors may have contributed to the effectiveness of the vocal tact teaching procedure and establishment of this repertoire, which is in line with the results of studies that examined the adult role in proposing appropriate learning conditions for children (Cruvinel, 2010).…”

“…Several studies have analyzed the role of the adult in proposing appropriate teaching conditions (Cruvinel, 2010;Gil, Oliveira, Sousa, & Faleiros, 2006;Greer & Ross, 2008;LeBlanc et al, 2009;Sousa, Souza, & Gil, 2013), planning the teaching so that the child is exposed to the stimulus for a determined number of times (Antoniazzi, Domeniconi, & Schmidt, 2014;Gurteen, Horne, & Erjavec 2011;Sousa et al, 2013) and also as a provider of the conditions subsequent to the response(s) that are reinforcers (Gil, Oliveira, & McIlvane, 2011;Sousa, Garcia, & Gil, 2014). In the study reported here, the adult that proposes appropriate teaching conditions is represented by the researcher, who adopted a favorable method for the study and, simultaneously, needed to consider the requirements of the target population, since they were children at risk of social vulnerability.…”
