Abstract Details

2005, Doctor of Philosophy, Ohio State University, Psychology.
Recent work on auditory pitch perception has shown that when listeners hear a sequence of tones increasing or decreasing in frequency, their judgments regarding the pitch of a tone appear to shift in the direction implied by the immediately preceding context sequence. One explanation for these results is that expectations are generated by exposure to a dynamic frequency pattern and as a result listeners make systematic pitch judgment errors specific to continuation of the frequency pattern. The main goal of this study is to determine whether dynamic intensity changes, like dynamic frequency changes, also contribute to pattern-based expectations in listeners. In a series of four experiments, listeners heard context sequences of tones that changed dynamically in frequency and intensity, and judged whether the pitch of a variable final tone (probe) was the same as or different from the immediately preceding tone. Experiment 1 sequences comprised simple monotonically changing frequency and intensity patterns. In Experiment 2, listeners heard longer sequences that implied periodically changing frequency and intensity patterns. And using the same frequency patterns from Experiment 2, Experiment 3 incorporated regularly recurring intensity accents and sequences in Experiment 4 included randomly occurring intensity accents. Results are discussed in terms of hypotheses associated with internalized physical principles, pattern-based expectations, and dimensional congruency.
