GARCIA, Andrés  e  BENJUMEA, Santiago. Facilitation of bi-directional relationships in pigeons using a transfer task after training in discrimination of own behavior. Univ. Psychol. [online]. 2007, vol.6, n.2, pp. 441-450. ISSN 1657-9267.

An experiment was carried out in which 10 pigeons were trained in a task of conditional discrimination of their own behavior. The birds learned that when the sample had consisted on responding to the left (right) with two white keys, they should choose the red (green) comparison to be reinforced. Once the animals had learned this task, they were passed to a test phase. In short, 5 pigeons were trained in a positive transfer, where the sample was now the red (green) key they had to choose the left (right) comparison to obtain the reinforcer. On the contrary, the other 5 pigeons received a training of negative transfer, where the task consisted in that with a red (green) sample they should choose the right (left) comparison to be reinforced. The obtained data indicate that the performance of those subjects of the group in which there was coherence among the phases went superior to that of those subjects of the group where there was not this coherence. The results are interpreted in connection with the importance that the discrimination of the own behavior has in the derivation of bidirectional relationships.
