Cross modal transfer of a conditional flexion response in dogs.

Two experiments investigated cross modal transfer of a conditional flexion response. In the first experiment, two dogs with extensive experimental past histories transferred a discrimination based on the pattern of presentation of auditory stimuli to a comparable pattern of visual stimuli. A second experiment with a naive dog demonstrated that such stimulus patterning also occurred from visual to auditory modalities. Additional tests showed that transfer was based on the relationship between discriminative stimuli and that the negative stimulus in the second modality was actively inhibitory. The data were discussed with reference to general attentiveness and rudimentary concept learning.
