Acoustic determinants of infant preference for motherese speech
Open accessAbstract
Three experiments investigated possible acoustic determinants of the infant listening preference for motherese speech found by Fernald 1985. To test the hypothesis that the intonation of motherese speech was sufficient to elicit this preference, it was necessary to eliminate lexical content and to isolate the three major acoustic correlates of intonation: (1) fundamental frequency (Fo), or pitch; (2) amplitude, correlated with loudness; and (3) duration, related to speech rhythm. Three sets of auditory reinforcers were computer-synthesized, derived from the Fo (Experiment 1), amplitude (Experiment 2), and duration (Experiment 3) characteristics of the infant- and adult-directed natural speech samples used by Fernald 1985. Thus, each of these experiments focused on particular prosodic variables in the absence of segmental variation. Twenty 4-month-old infants were tested in an operant auditory preference procedure in each experiment. Infants showed a significant preference for the Fo-patterns of motherese speech, but not for the amplitude or duration patterns of motherese.

“The universal speaking style used by caretakers around the world when they address infants, often called “motherese” or “parentese” (102), has been shown to be preferred over adult-directed speech by infants given a choice (103, 104).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
