To test this possiblity, we investigated whether newborns can match monkey facial and vocal gestures. Using a paired preference procedure, in Experiment 1 we presented pairs of different visible monkey calls in silence and then in the presence of
one or the other corresponding audible call and compared preferences across the silent and in-sound conditions. In Experiment 2, we presented the same monkey visible calls but this time together with a tone analog of the natural calls in the in-sound trials. We found that newborns looked longer at the matching visible call in the in-sound condition than in the silent condition in both experiments. These findings indicate that multisensory perceptual tuning Alectinib is so broad at birth that it enables newborns to integrate the facial and vocal gestures of other primates and that integration is based on newborns’ detection of audio-visual
temporal synchrony relations. “
“Infant social inhibition is associated with increased risk for LY294002 purchase anxiety later in life. Although both genetic and environmental factors are associated with anxiety, little empirical work has addressed how developing regulatory abilities work with genetic and environmental risk to exacerbate or mitigate problem behaviors. The current study was aimed at addressing this gap in research by investigating an early emerging regulatory behavior, attention control, in association with genetic and environmental risk for anxiety. Participants included 9-month-old adopted infants, their birth mothers, and adoptive parents (N = 361). Lifetime Clomifene diagnosis of birth mother social phobia was obtained using structured interviews. Adoptive parents completed self-report measures of anxiety symptoms. Infant social inhibition and attention control were coded during a stranger interaction and a barrier task,
respectively. Neither adoptive nor birth parent anxiety was directly associated with social inhibition. The association of attention control with social inhibition in infants was moderated by birth and adoptive parent anxiety symptoms. When infants of birth mothers with social phobia were raised by adoptive parents with high self-reported anxiety symptoms, greater attention control was associated with greater social inhibition. However, when raised by adoptive parents with low self-reported anxiety, greater attention control was associated with less social inhibition. “
“Fourteen-month-olds are sensitive to mispronunciations of the vowels and consonants in familiar words (N. Mani & K. Plunkett (2007), Journal of Memory and Language, 57, 252; D. Swingley & R. N. Aslin (2002), Psychological Science, 13, 480). To examine the development of this sensitivity further, the current study tests 12-month-olds’ sensitivity to different kinds of vowel and consonant mispronunciations of familiar words.
