Discussion: The Roots of Emerging Ecological Psychology

I briefly trace the topics presented in the 4 symposium papers in a cyclic order. Sheena Rogers' (this issue) paper discussing an example of J. J. Gibson's sense of 'information' (the horizon ratio) and Eleanor J. Gibson's (this issue) paper discussing affordance learning bring together the 2 core concepts of ecological psychology (information and affordance). Robert Lickliter (this issue) and Gene C. Goldfield (this issue), along with E. J. Gibson, discuss skill development in context utilizing comparative psychology and human infant research. For the recent history that holds these topics together, the early contributions of E. B. Holt and J. J. Gibson are emphasized.
