Visual prosody and speech intelligibility

Article Abstract:

People naturally move their heads when they speak, and our study shows that this rhythmic head motion conveys linguistic information. Three-dimensional head and face motion and the acoustics of a talker producing Japanese sentences were recorded and analyzed. The head movement correlated strongly with the pitch (fundamental frequency) and amplitude of the talker's voice. In a perception study, Japanese subjects viewed realistic talking-head animations based on these movement recordings in a speech-in-noise task. The animations allowed the head motion to be manipulated without changing other characteristics of the visual or acoustic speech. Subjects correctly identified more syllables when natural head motion was present in the animation than when it was eliminated or distorted. These results suggest that nonverbal gestures suchas head movements play a more direct role in the perception of speech than previously known.

Small body size at birth and behavioral symptoms of ADHD in children aged five to six years

Article Abstract:

The association between healthy full term infants smaller weight, length, ponderal index, head circumference, and the head circumference-to-length ratio at birth and the behavioral symptoms of attention deficit/hyperactivity disorder (ADHD) at the age of five to six years is studied. Results suggest that psychological adaptation in utero, indicated by small body size at birth, within term gestational range increase the susceptibility to behavioral symptoms of ADHD.
