This study examined the relation of 3-year core information-processing abilities to lexical growth and development. The core abilities covered four domains--memory, representational competence (cross-modal transfer), processing speed, and attention. Lexical proficiency was assessed at 3 and 13 years with the Peabody Picture Vocabulary Test (PPVT)…

This study identified deficits in executive functioning in pre-adolescent preterms and modeled their role, along with processing speed, in explaining preterm/full-term differences in reading and mathematics. Preterms (less than 1750 g) showed deficits at 11 years on a battery of tasks tapping the three basic executive functions identified by…

This study provides the first direct evidence of cognitive continuity for multiple specific information processing abilities from infancy and toddlerhood to pre-adolescence, and provides support for the view that infant abilities form the basis of later childhood abilities. Data from a large sample of children (N = 131) were obtained at five…

A controversial issue in the field of language development is whether language emergence and growth is dependent solely on processes specifically tied to language or could also depend on basic cognitive processes that affect all aspects of cognitive competence (domain-general processes). The present article examines this issue using a large…

The present report assesses information processing in the toddler years (24 and 36 months), using a cohort of preterms (less than 1750 g) and full-terms initially seen in infancy. The children received a battery of tasks tapping 11 specific abilities from four domains--memory, processing speed, attention, and representational competence. The same…

Although it is well established that preterms as a group do poorly relative to their full-term peers on tests of global cognitive functioning, the basis for this relative deficiency is less understood. The present paper examines preterm deficits in core cognitive abilities and determines their role in mediating preterm/full-term differences in IQ.…

Using data from a longitudinal study of preterms and full-terms, the present study examined the structure of infant cognition at 12 months, the extent to which five 12-month abilities (attention, processing speed, recognition, recall, and representational competence) mediated the relation from prematurity to mental development at 2-3 years, and…

Examined the effects of premature birth on ninety 11-year-olds' memory and processing speed, using the new Cognitive Abilities Test (CAT). Found that preterm subjects performed more poorly than their full-term counterparts on all CAT memory tasks, and that preterms were also slower on selected aspects of processing speed but not on motor speed.…

Examined developmental change and stability of visual expectation and reaction times among 5-, 7-, and 12-month-old term and preterm infants. Found that reaction times declined with age while anticipations increased. Infants with faster reaction times were more likely to anticipate upcoming events; this effect disappeared when time between stimuli…

Studied in three experiments the distribution and malleability of visual attention in 5-month-olds while they inspected large geometric designs. Established that infants who were short-lookers had novelty scores above chance, whereas long-lookers demonstrated chance responding. Illuminating different parts of visual display induced long-lookers to…

This study assessed cognitive processing speed among full-term and preterm infants when they reached 5, 7, and 12 months of age. Findings indicated that at all ages, preterms required about 20 percent more trials and 30 percent more time than full-terms to reach criterion on a novelty preference task. Among preterms, slower processing was…

Examined visual attention and implications for recognition memory in a longitudinal sample of full-term and preterm infants at 5, 7, and 12 months. Found differences between full-terms and preterms in several aspects of visual attention. Infants showed consistent attentional styles over various conditions. Shorter looks and higher shift rates…

This study examined the relation of information processing in 7-month-old preterms ([less than] 1750g at birth) and full-terms to Bayley Mental Development Indexes (MDIs) at 2 and 3 years. The infant measures were drawn from four cognitive domains: attention, speed, memory, and representational competence. Structural equation modeling showed that…

Examined contributions of cognitive processing speed, short-term memory capacity, and attention to infant visual recognition memory. Found that infants who showed better attention and faster processing had better recognition memory. Contributions of attention and processing speed were independent of one another and similar at all ages studied--5,…

Visual recognition memory is a robust form of memory that is evident from early infancy, shows pronounced developmental change, and is influenced by many of the same factors that affect adult memory; it is surprisingly resistant to decay and interference. Infant visual recognition memory shows (a) modest reliability, (b) good discriminant…
