ABSTRACT CERTAIN characteristics of the human voice at normal levels have a great influence on the neonate1, and infants 1 month old can detect fine differences in speech-like sounds2,3. This enables a selective response to take place when the child meets adults. From birth, babies will turn towards the source of a sound, and this orientation to a voice helps them to learn about faces. We have also observed that infants are more interested in their mother's face when she is talking.

    ABSTRACT: While survival rates for preterm infants have increased, the risk for adverse long-term neurodevelopmental and behavioral outcomes remains very high. In response to the need for novel, evidence-based interventions that prevent such outcomes, we have assessed Family Nurture Intervention (FNI), a novel dual mother-infant intervention implemented while the infant is in the Neonatal Intensive Care Unit (NICU). Here, we report the first trial results, including the primary outcome measure, length of stay in the NICU and, the feasibility and safety of its implementation in a high acuity level IV NICU. The FNI trial is a single center, parallel-group, randomized controlled trial at Morgan Stanley Children's Hospital for mothers and their singleton or twin infants of 26--34 weeks gestation. Families were randomized to standard care (SC) or (FNI). FNI was implemented by nurture specialists trained to facilitate affective communication between mother and infant during specified calming interactions. These interactions included scent cloth exchange, sustained touch, vocal soothing and eye contact, wrapped or skin-to-skin holding, plus family-based support interactions. A total of 826 infants born between 26 and 34 weeks during the 3.5 year study period were admitted to the NICU. After infant and mother screening plus exclusion due to circumstances that prevented the family from participating, 373 infants were eligible for the study. Of these, we were unable to schedule a consent meeting with 56, and consent was withheld by 165. Consent was obtained for 150 infants from 115 families. The infants were block randomized to groups of N = 78, FNI and N = 72, SC. Sixteen (9.6%) of the randomized infants did not complete the study to home discharge, 7% of those randomized to SC and 12% of FNI infants. Mothers in the intervention group engaged in 3 to 4 facilitated one- to two-hour sessions/week. Intent to treat analyses revealed no significant difference between groups in medical complications. The mean length of stay was not significantly affected by the intervention. There was no significant effect demonstrated with this intervention amount on the primary short-term outcome, length of stay. FNI can be safely and feasibly implemented within a level IV NICU.Trial registration: Clinicaltrials.gov: NCT01439269.

    ABSTRACT: This essay reviews some of the problems that face biolinguistics if it is to someday succeed in understanding human language from a biological and evolutionary viewpoint. Although numerous sociological problems impede progress at present, these are ultimately soluble. The greater challenges include delineating the computational mechanisms that underlie different aspects of language competence, as implemented in the brain, and under-standing the epigenetic processes by which they arise. The ultimate chal-lenge will be to develop a theory of meaning incorporating non-linguistic conceptual representations, as they exist in the mind of a dog or chimpan-zee, which requires extensions of information theory incorporating context-dependence and relevance. Each of these problems is daunting alone; to-gether they make understanding the biology of language one of the most challenging sets of problems in modern science.
