Congruency Effects with Dynamic Auditory Stimuli
by
Bruce N. Walker
ABSTRACT
As auditory displays become more common it is increasingly important to
understand the perception of complex and dynamic auditory stimuli and how
the information contained in the various dimensions of these stimuli
influences performance. In the present study listeners made keypress
responses to dynamic sound stimuli which started high or low in pitch and
became higher or lower in pitch during each trial. The results showed
that pitch and pitch change interacted in an asymmetrical manner, with
pitch information intruding more on judgments of pitch change than vice
versa. Neither pitch nor pitch change interacted with vertically
arranged responses to produce the strong spatial S-R compatibility
effects that were expected based on previous research and on descriptions
of pitch in everyday language. Analytic versus holistic listening
strategies or the physical location of the sounds may affect interactions
of the stimuli and responses in this type of selective listening task.
