Linda Kreger Silverman, Ph.D., is a licensed psychologist. She founded and directs the Institute for the Study of Advanced Development, and its subsidiaries, Gifted Development Center (GDC) and Visual-Spatial Resource in Denver, Colorado. In the last 35 years, she has studied over 6,000 children who have been assessed at GDC, the largest data bank on this population. This research enabled the creation of extended norms on the WISC-IV. In 1981, she originated the concept of the “visual-spatial learner” (VSL) and has created methods of identifying and teaching this population. Her Ph.D. is in educational psychology and special education from the University of Southern California. For nine years, she served on the faculty of the University of Denver in counseling psychology and gifted education. She has been studying the psychology and education of the gifted since 1961 and has written over 300 articles, chapters and books, including Counseling the Gifted and Talented, Upside-Down Brilliance: The Visual-Spatial Learner and Advanced Development: A Collection of Works on Gifted Adults. Her latest book, Giftedness 101 (New York: Springer, 2013), went into third printing within 6 months of its release. A popular presenter, Linda has keynoted conferences in New Zealand, Singapore, Hong Kong, Australia, Denmark, Ireland, the U.S., and others.
Barbara (Bobbie) Jackson Gilman, M.S., Associate Director, has worked with Linda Silverman, beginning just after her own sons were tested at the GDC in 1991. Bobbie has a background in psychology and child development from Duke and Purdue. She consults with parents and educators, plans and interprets assessment to guide educational planning, participates in research using our data on over 6000 gifted children, provides teacher training (e.g., a 3-day retreat for teachers from Edmonton, Alberta), and promotes effective gifted assessment (she has worked with Pearson, Riverside, and Pro Ed to respond to gifted needs in test development). Her books include the award-winning Academic Advocacy for Gifted Children: A Parent's Complete Guide and Challenging Highly Gifted Learners. She co-chairs with Dan Peters the National Association for Gifted Children's Assessments of Giftedness Special Interest Group (SIG), formerly the Assessment Task Force, which researched the WISC-IV and suggested best practices for its use for gifted identification. Bobbie spearheaded the SIG’s work on twice-exceptional issues, including the 2013 “Critical Issues in the Identification of Gifted Students with Co-existing Disabilities: The Twice-Exceptional”, which provided a basis for NAGC’s Position Statement, “Ensuring Gifted Children with Disabilities Receive Appropriate Services: Call for Comprehensive Assessment” (2013).
