INFORMATION

Psicothema was founded in Asturias (northern Spain) in 1989, and is published jointly by the Psychology Faculty of the University of Oviedo and the Psychological Association of the Principality of Asturias (Colegio Oficial de Psicólogos del Principado de Asturias).
We currently publish four issues per year, which accounts for some 100 articles annually. We admit work from both the basic and applied research fields, and from all areas of Psychology, all manuscripts being anonymously reviewed prior to publication.

Pese a la aparente simpleza del condicionamiento pavloviano, la investigación acerca de sus mecanismos ha despertado considerable debate, como es el caso de la disputa acerca de si los estímulos que se asocian son codificados en forma <<elementalista>>(un estímulo compuesto es equivalente a la suma de sus componentes) o <<configuracional>>(un estímulo compuesto es un ejemplar único). Esta controversia es evidente en la abundante investigación sobre las predicciones contrastantes de los modelos elementalistas y configuracionales. Recientemente, han surgido soluciones mixtas, con las ventajas de ambos enfoques, pero difíciles de evaluar dada su complejidad. Este artículo presenta un programa computacional para ejecutar simulaciones de un modelo mixto (replaced elements model o REM). Se incluyen instrucciones y ejemplos para utilizar el simulador con fines investigativos y educacionales.

Development of a computer program to simulate the predictions of the replaced elements model of Pavlovian conditioning. Despite of the apparent simplicity of Pavlovian conditioning, research on its mechanisms has caused considerable debate, such as the dispute about whether the associated stimuli are coded in an <<elementistic>>(a compound stimuli is equivalent to the sum of its components) or a <<configural>> (a compound stimuli is a unique exemplar) fashion. This controversy is evident in the abundant research on the contrasting predictions of elementistic and the configural models. Recently, some mixed solutions have been proposed, which, although they have the advantages of both approaches, are difficult to evaluate due to their complexity. This paper presents a computer program to conduct simulations of a mixed model (replaced elements model or REM). Instructions and examples are provided to use the simulator for research and educational purposes.
