Information Processing at 1 Year: Relation to Birth Status and Developmental Outcome during the First 5 Years.

As part of a longitudinal study of high-risk preterm infants (birthweight less than 1500 g) and a low socioeconomic status (SES) comparison group of full-term infants, measures of information processing were obtained at 1 year : visual and tactual recognition memory, cross-modal transfer, and object permanence. Of these, cross-modal transfer was the most strongly related to later intelligence, correlating with outcome at 1.5, 2, 3, 4, and 5 years for preterms and from 3-5 years for full-terms (rs=44 to 54) ; relations with outcome were independent of SES, maternal education, medical risk, and early Bayley scores. When this 1-year measure of cross-modal transfer was combined with 7-month visual recognition memory, 35%-51% of the variance in 3-,4-, and 5-year IQ was explained

Auditory consequences of early mild hearing loss associated with otitis media

Two groups of children received periodic documentation of their middle ear status by pneumatic otoscopy in the first year of life and had hearing sensitivity estimated by multiple auditory brainstem response (ABR) assessments during the same period. One group was considered otitis media (OM)-positive, with repeated bilateral episodes of OM and mild conductive hearing loss. The second group was considered OM-free with normal middle ear function bilaterally and normal hearing sensitivity in the first year of life. Childrens higher-order auditory abilities were examined at 4, 6 and 9 years of age. Various measures such as speech recognition-in-competition, visual-auditory learning, sound blending, auditory memory, and masking level difference estimates were utilized to probe the childrens auditory abilities. Results show that children with a first-year history of otitis media demonstrate deficits in the long term in some aspects of higher-order auditory processing. Performance appears to be associated with the mild hearing loss experienced during an important period of early development.

Language : a partial link between infant attention and later intelligence

To extent to which the relation between infant visual recognition memory(indexed by novelty scores) and later IQ was accounted for by a common association with language was examined. In a longitudinal study, problems of visual recognition memory were administered at 7 months, scales of language development at 2.5, 3, and 4 years, and intelligence tests at 3, 4, and 5 years

Long Term Communication Deficiencies in Children with Otitis Media During Their First Year of Life

A cohort of lower socio-economic children who experienced multiple episodes of otitis media (OM) during their first year of life were compared to a group of children who were largely free of OM during their first year. Both groups were followed until 9 years of age. The data indicate that some children with positive histories of OM performed poorer on a variety of communicative tasks across the 9 year age span than the children with the negative histories of OM. The results suggest that the effect of otitis media and its accompanying hearing loss on communication skills may extend throughout childhood.

Long term language deficiencies in children with otitis media during their first year of the life

A cohort of lower socio-economic children who experienced multiple and prolonged episodes of otitis media (OM) during their first year of life were compared to an equivalent group of children who were largely free of OM during their first year. Both groups were followed until 9 years of age. The data indicate that children with positive histories of OM performed poorer on a variety of Iinguisitc tasks across the nine year age span than the children with the positive histories of OM. The results suggest that the effect of the otitis media and its accompanying hearing loss on communication skills may extend throughout childhood.
