"Meticulously scholarly. He shares his thought processes with the reader, explaining why he does things, how, and his observations would please Darwin, Piaget, all the greats! Each time I try to put the book down, the next section beckons and looks interesting." - Tina Bruce, Honorary Visiting Professor of Early Childhood Studies, Roehampton University, UK"Starting from Scratch is not your typical psychology text. It combines careful observation with an interpretative lens that is seldom encountered in scientific work. Professor Matthews' work supplements and extends previous studies and provides a valuable database on chimpanzees' representational capabilities." - Kerry Lee, Associate Professor, Applied Cognitive Development Lab, National Institute of Education, Singapore
