Dear all,
Next week, in addition to Andreas Roepstorff's talk on Wednesday at 5 pm,
we will have an extra seminar by Greg Bryant on THURSDAY, at 11 am. The
abstract is below:
Greg Bryant (UCLA)
Date: THURSDAY, October 31, 2013, 11 AM
Location: Cognitive Development Center, Hattyú u. 14, 3rd floor
Title: Acoustic forms of intentional signals.
The sound of animal vocalizations is shaped by communicative function and
evolutionary history. In this talk I will describe research that examines
two kinds of vocal signals in humans: infant-directed (ID) speech and
spontaneous laughter. Acoustic features of ID speech are functionally
specialized for getting infants’ attention and communicating intentions.
While cultural variation exists in the frequency of its occurrence, the
production and recognition of ID speech is similar across quite different
societies. Analysis of the adaptive functions of ID speech provides the
best level of explanation for its acoustic structure. In the case of
laughter, mechanistic and phylogenetic factors can play a more central role
in understanding its structural features, particularly in the acoustic
differences between spontaneous laughter and volitional laughter which
provide differential cues of speaker intent in social interaction. I will
conclude with some thoughts about how Tinbergen’s four questions are
differentially useful depending on the specific behavior one is examining.
PLEASE NOTE: Our seminar room has a limited capacity. Please arrive early
to ensure you get a seat.
