The purposes of this present study are (1) to follow the development of preterm as compared with that of full-term infants born to teenage v adult mothers belonging to a lower SES group; and (2) to assess the effects of an intervention provided for a subsample of the preterm infants born to teenage mothers.

Infants' looking and looking-away behaviors, as well as cardiac responses to mothers' spontaneous and imitative faces and to dolls' animated and still faces, were recorded for 18 term and 19 preterm infants when they were three months old. (JMB)

Compared spelling of children who speak General American English and those who speak Southern British English. Found that spelling errors of children with spelling ages of 6 to 7.5 reflected characteristics of their dialect, and that at older spelling ages, British children made overgeneralization errors reflecting their dialect. Concluded that…

Examined development of displaced reference in four deaf children who used homesign and in 18 hearing children. Found that deaf children referred to the nonpresent less frequently and at later ages than hearing children, both groups followed similar developmental paths. Deaf children evoked the nonpresent by generating novel gestures, modifying…

Five experiments examined whether young children believe a lie tellers' implausible statement about a misdeed when the statement violates their developing knowledge of the reality- fantasy distinction. Findings suggested that 5- and 6-year-olds tended to report that the individual making the implausible statement actually committed the misdeed; 3-…

Investigated emotional responses to the still-face paradigm in preterm and full-term black infants. Preterm infants spent less time than full-term infants displaying big smiles in one episode, and showed a less pronounced decrease in big smiles in a second episode. Results confirm the robustness of the still-face paradigm. (HTH)

Pooled data from previous studies in which autistic, mentally handicapped, and normal young children had been tested on theory of mind tasks. Found that normal children at a verbal mental age of four years, but autistic children at a verbal mental age of more than nine years, had a 50% chance of passing the theory of mind tests. (BC)

Observers and mothers rated infant behavior in the home on dimensions of temperament once a week for eight weeks. Although week-to-week correlations were modest, aggregates of the eight observations had high reliability for both observers and mothers. When direct observations were compared with mother reports, little evidence of mother-observer…

Examined differences in acoustic characteristics of cries, both early and late, within a prolonged crying bout. Results indicated that late cries appeared to result from a smaller number of factors than did early cries. Results support notions that crying bouts settle into a regular cry with acoustic features matching a theoretical model of cry…

Compared 18 children's and 18 adults' ability to detect information conveyed through the representational hand gestures of videotaped children verbally and gesturally explaining their problem-solving reasoning. Found that children and adults recalled information conveyed through representational gestures. Mismatching gesture negatively affected…

First- and fifth-grade only-children and children with siblings completed 11 cognitive tasks to investigate differences in cognitive abilities that may exist due to the Chinese 1-child family planning program. Superiority of grade one only-children over children with siblings appeared for memory processes, language skills, and mathematics.…

Examined performance on neuropsychological tests (tapping the medial temporal lobe and related limbic structures, and the dorsolateral prefrontal cortex, respectively) in relation to performance on tasks assessing autistic symptoms in young children with autism, and developmentally matched children with Down syndrome or typical development.…

Two studies determined the extent to which feedback could improve eighth graders' and adults' decision-making. Results showed that neither benefited from verbal feedback in choosing between easy and hard questions to earn points. Adults benefited more than adolescents from outcome feedback. Adults also benefited more than adolescents in context of…

Event-related potentials (ERPs), in response to 4 facial expressions of fear, angry, happy, and sad, were collected from 72 institutionalized children (IG), ages 7 to 32 months, in Bucharest, Romania, and compared with ERPs from 33 children, ages 8 to 32 months, who had never been institutionalized (NIG). The NIG and IG exhibited different…

This study examined the effect of a mother-baby intervention on the quality of mother-child interaction, infant-mother attachment security, and infant socioemotional functioning in a group of depressed mothers with infants aged 1-12 months. A randomized controlled trial compared an experimental group (n = 35) receiving the intervention (8-10 home…
