Biography —

I received my Ph.D. in Psychology (1981) from the State University of New York at Buffalo. After one year at Youngstown State University (1981-1982), and six years (1982-1988) as a research associate with the Bureau of Child Research at the University of Kansas, I joined the faculty of the College of Liberal Arts and Sciences at the University of Kansas in 1988, and have been a member of the Department of Psychology since January of 2002. My research interests are in the developmental cognitive neuroscience of attention and learning, with a special focus on early individual differences in these areas and how they relate to the typical and atypical development of cognitive and intellectual function. I conduct research in laboratories at the KU Edwards Campus and the KU Medical Center, as well as at the Wakarusa Research Facility in Lawrence.

Salley, Brenda, (Principal), John, Colombo, (Co-Principal), Visual attention, joint attention, and emergent language in infancy, K99HD07588, National Institutes of Health (National Institute of Child Health and Human Development), $392,850, Submitted 01/01/2013 (07/01/2013 - 07/31/2018) . DESCRIPTION (provided by applicant): Emergent lines of research and theory suggest the importance of considering the contributions of social and non-social attentional cues for language acquisition and performance. However, in the current literature, these contributions have been examined separately. The overall aim of the current application is to systematically examine whether infants' early visual attention (to social and non-social targets) predicts their joint attention, and whether the co-development of both together predicts the emergence of language. Two specific aims (which correspond to the K99 and R00 phases) are intended to address current gaps in our knowledge. The first aim (K99) will test the hypothesis that social attention differentiates from general attentional processes during the first year of life. To date,it is unknown whether attention regulation skills differ in the context of social and non-social input across development and how these skills map on to joint attention behaviors. Joint attention may reflect development of general aspects of attention, or alternatively, it may reflect socially specific attention (i.e., attention regulation in the context of other social agents). The second am (ROO) will test the hypothesis that across the first two postnatal years, visual attention and join attention will make independent and unique contributions to language outcomes. Although basic measures of visual attention and measures of joint attention have been independently associated with language outcomes, their relative contributions across development have not been systematically examined. Our recent work suggests visual attention and joint attention account for unique variance in language variability in the second year of life. Federal. Status: Funded.

Colombo, John, (Principal), Carlson, Susan, (Principal), Gustafson, Kathleen, (Co-Principal), Gajewski, Byron, (Co-Principal), DHA supplementation and pregnancy outcome, Eunice Shriver National Institute for Child Health and Human Development, $2,858,697, Submitted 10/01/2011 (07/01/2012 - 07/31/2017) . DESCRIPTION (provided by applicant): This application seeks to renew project R01 HD047315, which supported the conduct of a randomized clinical trial of a high level of supplementation of docosahexaenoic acid (DHA) during the prenatal period (ClinicalTrials.gov ID: NCT00266825). We achieved the enrollment and follow-up goals of the original RCT and, most importantly for the current proposal, we have retained the planned large cohort of children born to women enrolled in the parent trial. Infants enrolled and followed to 18 months of age in this trial are now entering a particularly important period of cognitive and intellectual development, and the successful retention of the current sample allows for an unprecedented opportunity to determine if prenatal supplementation of DHA affects preschool and school-age outcomes that predict successful school performance and adaptive behaviors. The different skills that emerge at these ages build on early components of cognition, which have been positively associated with higher DHA status in both observational studies and clinical trials. We propose to test these infants on a semi-annual basis from 24 through 72 months of age employing outcomes that assess four domains of development that are critical to health, adjustment, and well-being through adulthood: (a) higher-order cognition (memory, attention, and executive function), (b) language processing and preliteracy skills, (c) adaptive regulation (self-regulation skills related to behavioral problems, school performance, and child psychopathology), and (d) intelligence. The proposed assessments will allow us to determine whether prenatal nutritional supplementation with DHA affects child health and development. The findings could contribute to evidence-based policy on prenatal nutrition. In addition, the evidence from this renewal would address hypotheses concerning fetal programming and human behavior that are currently at the forefront within the field of health, development and nutrition.

Colombo, John, (Principal), Smith, Peter, (Co-Principal), Kansas Intellectual and Developmental Disabilities Research Center, P30HD02528-45, National Institutes of Health (Eunice Shriver National Institute of Child Health and Human Development), $8,109,647, Submitted 03/01/2012 (07/01/2012 - 07/31/2017) . DESCRIPTION (provided by applicant): Core Support for five years is requested for the competitive renewal of the Kansas Intellectual and Developmental Disabilities Research Center (KIDDRC). The KIDDRC, now in its 44th year, has played a major international role in generating highly effective biobehavioral interventions aimed at the causes, prevention, and treatment of intellectual and developmental disabilities and related secondary conditions, and in delineating basic knowledge of the underlying biology of typical and atypical development. Since its inception, the Center has supported a balanced portfolio of behavioral, biological, and biobehavioral research. Building on its rich history, a unique contribution of the Center in the future will be the development of biologically-informed interventions and treatments. The mission of the KIDDRC is to support high quality basic and applied research relevant to the causes and prevention of intellectual and developmental disabilities and the prevention and remediation of associated secondary conditions. To achieve this mission, the KIDDRC is designed to accomplish three objectives. First, to develop and support new interdisciplinary basic and applied research initiatives directly relevant to the Center's mission, bringing together scientists across the Kansas Center as well as promoting collaborative ventures with researchers at other institutions. Second, to provide cost-effective, scientifically generative, state of the art core services, resources, and facilities that directly enhance the quality and impact of science produced by center investigators and their collaborators. Third, to provide highly efficient, cost-effective systems for planning, developing, managing, coordinating, and disseminating research activities associated with the center. The KIDDRC's research program is organized around four integrated thematic areas that each reflects a topic of central importance to IDD, comports with our scientific directions, and draws upon our research strengths. These themes are: 1) language, communication, and cognition of IDD; 2) risk, prevention, and intervention in IDD; 3) neurobiology of IDD; 4) cellular and molecular biology of early development. To coordinate and support the research activities of the 84 investigators and co-investigators and 88 research projects associated with these themes, four core units are proposed: a) Communication and Administration; b) Biobehavioral Measurement; c) Research Design and Analysis; d) Integrative Imaging.
