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 Psicología 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.

Se realizó un experimento con sujetos humanos de edades comprendidas entre los 7 y los 53 años en el que se utilizó un procedimiento de discriminación condicional con muestras compuestas formadas por estímulos exteroceptivos (figuras geométricas coloreadas) y propioceptivos (diferentes formas de señalar tales figuras). De esta forma, los sujetos fueron entrenados a emitir una conducta diferencial ante cada muestra y a elegir la comparación correcta. Posteriormente se evaluó la ejecución de los sujetos tanto en una discriminación condicional con muestra simple para cada uno de los componentes del anterior estímulo compuesto (sólo conducta y sólo figuras coloreadas) como mediante un procedimiento de competencia. Los resultados indicaron que los estímulos exteroceptivos adquirieron mayor control sobre la conducta de elección que los estímulos propioceptivos. Se discuten los resultados en relación con la importancia que la discriminación de la propia conducta puede tener en la génesis del control discriminativo bidireccional.
Competence between propioceptive and exteroceptive conditional stimuli in a conditional discrimination task. An experiment was carried out with humans as subjects, aged between 7 and 53, in which a conditional discrimination procedure with compound samples made up by exteroceptive (colored geometric shapes) and proprioceptive stimuli (different ways of pointing at them) was used. Thus, subjects were trained to perform differently in the presence of each sample, and later to choose the correct comparison. They were then evaluated in a conditional discrimination with unitary samples for each one of the components of the previous compound stimulus (only behavior and only colored shapes). For this, a competition procedure was designed. Results showed that the exteroceptive stimuli exerted more influence over the chosen behavior than the proprioceptive stimuli. Results are discussed in relation to the importance that one’s own behavior discrimination may have in the origins of bi-directional discriminative control.
