La densidad de la retroalimentación como modulador de la variabilidad y estereotipia conductual

Existe evidencia demostrando que la variabilidad y la estereotipia son dimensiones operantes de la conducta, las cuales han sido estudiadas bajo distintos métodos y tareas, con humanos y otras especies animales (Neuringer, 1992; 1993; 2009). La variabilidad operante es aquella que puede ser controlada directamente por las consecuencias contingentes a su producción (Lee, Sturmey & Fields, 2007; Neuringer 2009).

The Law of Expect or a Modified Law of Effect?

Blaisdell, A. P., Stolyarova, A., & Stahlman, W. D.. (2016). The Law of Expect or a Modified Law of Effect?. Conductual, 4(2), 61-90. presented at the 01/08/2016.

Variation is fundamental to Darwin’s theory of evolution by natural selection (Darwin, 1859). The process of selection operates on the substrate of heritable phenotypic variation to shape the evolution of traits. As powerful as it is, there are limits to the scope of evolutionary processes. Most notably, evolution does not act on the individual, but only on populations of individuals. Thus, the forces of natural selection do not continue to shape an individual’s phenotype.

Analysis of sequential patterns of stereotypy and variability in human conditional discrimination tasks

The validity of experimentally analyze behavioral stereotypy and variability in humans and non-human species has been well-documented in the operant literature (e,g., Neuringer, 2004). Although stereotypy and variability have sometimes been examined separately, these two forms of behavior are often confronted. In the first case, persistence in repetition responses can lead to aberrant behavior of an obsessive or addictive type (among other behavioral disorders). Variability, in contrast, has been associated with behaviors that lead to originality, creativity or inventiveness.

Entrenamiento de variabilidad y estereotipia

Zepeda-Riveros, I., & Martínez-Sánchez, H.. (2013). Entrenamiento de variabilidad y estereotipia. Conductual, 1(1), 51-71. presented at the 01/04/2013.

El estudio de la variabilidad y estereotipia conductual humana recientemente ha tenido un interés creciente. Ha sido bien documentado que tanto la variabilidad como la estereotipia conductual pueden ser entrenadas en humanos y otras especies y que las consecuencias pueden ejercer un control diferencial sobre la conducta de variar, o bien de repetir (Neuringer, 2002).
