Synthetic pure tone sequences and complex natural vocalizations were used in two separate experiments. These experiments were the first comprehensive investigation of the effects of auditory attention on the auditory streaming process in behaving animals, which adds to studies investigating the mechanisms of auditory processing in animal models. In experiment 1, I used modified ABAB... patterned two-stream mixtures and replicated the buildup effect in an objective auditory streaming paradigm in budgerigars. By adding different distractors in an unattended stream, I investigated the effect of attention capture on the auditory streaming process. Sequentially unpredictable distractors in the unattended stream deteriorated the buildup process in birds, and perceptually more salient distractors tended to be more influential. However, making the distractors sequentially predictable mitigated the deterioration effect elicited by attention capture in birds. Different from humans, distractors from the intensity or frequency feature dimension tended to affect birds' attention to the frequency dimension similarly. In experiment 2, birds' sensitivity to spectral or temporal modulations in conspecific vocalizations were measured in conditions requiring different attentional demands. Compared to spectral modulations, birds' sensitivity to temporal modulations were more susceptible to birds' attentional sets. The presence of competing backgrounds extended the birds' attention spans during the task. Distractors appearing right before the target narrowed the birds' attentional spotlight, which facilitated their discrimination of the target. In sum, birds' attentional sets can have a critical influence on their perception of complex auditory scenes, which should be considered in comparative neurophysiological studies.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
