Effects of varying the temporary position of the intruded stimulus during the delay interval and of the consistency and inconsistency of the sample-reinforcer relationship. Univ. Psychol. [online]. 2007, vol.6, n.2, pp. 451-463. ISSN 1657-9267.

The present study evaluated the effect of varying the temporary position of intruded stimuli during the delay interval and the consistency and inconsistency in the relationship sample-reinforcer in a delayed matching to sample task. For three pigeons the intruded stimulus maintained a consistent relationship with the sample-reinforcer relationship, while for other three pigeons the intruded stimulus maintained a inconsistent relationship with the sample stimulusreinforcer correlation. In both groups the position of the intruded stimulus was varied during the delay (begin, half and final). The discrimination index was lower in the final and half position in both groups. The results are discussed in terms of the relationship that have the temporary variables about the different properties that develop the stimuli.
