“…If such spatial orienting is related to the automatic shift of eye movements to particular types of discrepant elements within visual arrays, then a discussion of the small volume of literature on pop-out effects in infancy is warranted here. This issue has been addressed with infants in both attentional (Catherwood et al 1996a, Quinn & Bhatt 1998, Salapatek 1975, Van Giffen & Haith 1984 and memory (e.g. Gerhardstein et al 1999; Rovee-Collier et al 1996see Bhatt 1997, for a review) paradigms.…”

Over the past decade, the study of attention in infancy has seen dramatic progress. This review delineates four attentional functions (alertness, spatial orienting, attention to object features, and endogenous attention) that are relevant to infancy and uses these functions as a framework for summarizing the developmental course of attention in infancy. Rudimentary forms of various attentional functions are present at birth, but each of the functions exhibits different and apparently dissociable periods of postnatal change during the first years of life. The role of attention in development should therefore be considered in the context of interaction among different systems at different levels of maturity during the first years of life.

“…However, what little work exists on masking in infants suggests that masking would not occur in our study (Lasky and Spiro, 1983;Catherwood, 1994;Catherwood et al, 1996). These studies have typically used much shorter target stimulus presentations than us (e.g.…”

Young infants are very sensitive to feature distribution information in the environment. However, existing work suggests that they do not make use of correlation information to form certain perceptual categories until at least 7 months of age. We suggest that the failure to use correlation information is a by-product of familiarization procedures that encourage infants to over encode individual exemplars rather than relations across exemplars. By changing the exemplar presentation regime to one in which exemplars are rapidly (2 s durations) and repeatedly presented we find that 4-month-olds can form perceptual categories on the basis of feature correlation information. In addition, this ability emerges rapidly between 114 and 134 days. We argue that the ability to process correlation information is present very early on but that the demonstration of that ability in categorization tasks is mediated by the demands of the task the infant is tested with.

“…Colombo (2001) trained 3-, 6-, and 9-month-olds to an association between an auditory reinforcement and attention to visual/spatial displays. Colombo (2001) reviewed similar studies by Harman et al (1994) and work by Catherwood et al (1996) on determining the time course of the processing of visual features and their joining compounds in 5-to 6-month-olds. It is important to note that tasks such as these are currently used to examine how the infant brain develops and functions.…”

Comparable measures of cognitive function in human infants and laboratory animals to identify environmental health risks to children.

The importance of including neurodevelopmental end points in environmental studies is clear. A validated measure of cognitive function in human infants that also has a homologous or parallel test in laboratory animal studies will provide a valuable approach for large-scale studies. Such a comparable test will allow researchers to observe the effect of environmental neurotoxicants in animals and relate those findings to humans. In this article, we present the results of a review of post-1990, peerreviewed literature and current research examining measures of cognitive function that can be applied to both human infants (0-12 months old) and laboratory animals. We begin with a discussion of the definition of cognitive function and important considerations in cross-species research. We then describe identified comparable measures, providing a description of the test in human infants and animal subjects. Available information on test reliability, validity, and population norms, as well as test limitations and constraints, is also presented.
