![عکس صفحه اول مقاله: Use of samples differing markedly in salience may encourage use of a single-code/default strategy in matching-to-sample in pigeons Use of samples differing markedly in salience may encourage use of a single-code/default strategy in matching-to-sample in pigeons](/preview/png/919040.png)
To test the hypothesis that pigeons will only code the more salient sample when samples differ markedly in salience, pigeons were trained with samples consisting of a 2-s presentation of food (highly salient sample) and an 8-s presentation of keylight (less salient sample). During retention testing, pigeons tended to respond at longer delays as if an 8-s keylight sample had been presented. This finding is consistent with use of a single-code/default strategy in which only the 2-s food sample was coded and the comparison associated with an 8-s keylight sample was selected by default in the absence of memory for the salient 2-s food sample. Hence, a marked difference in sample salience appears to encourage use of a single-code/default strategy.
