Many of the tasks thought to depend on processing speed are the same ones in which many pre-term infants perform poorly when older, including measures of intelligence, language and academic achievement, such as reading, arithmetic and spelling. Among pre-terms, slower processing speed is also associated with greater medical risk, such as respiratory distress syndrome.
To explore whether individual differences in processing speed have their roots in infancy, Susan A. Rose, Ph.D., Judith F. Feldman, Ph.D., and Jeffery J. Jankowski, Ph.D., of Albert Einstein College of Medicine - Children's Hospital at Montefiore studied 153 full-term and 59 pre-term infants (born weighing less than four pounds) to assess processing speed at five, seven and 12 months of age. The infants were presented with a series of pictures of paired faces, one that remained the same across the trials and one that changed. The trials continued until an infant showed a consistent preference for the new faces.
The researchers found that as early as five months of age, pre-terms were significantly slower at processing the paired faces than full-terms. Preterms took about 20 percent more trials and about 30 percent more time than full-terms to study the paired faces and reliably recognize the new faces. The differences were similar at all three ages with no evidence found that the performance gap narrowed with age or that the pre-terms caught up.
The results of the study are consistent with previous res
