Introduction to Developmental Science (1) Theory and Methods University of Tokyo Press By Keiko Takahashi, Ryozo Yukawa, Toshiyuki Ando, and Hiroko Akiyama I accidentally purchased the wrong series. This is a valuable book, so I would like to pass it on to someone who can use it. There are no markings, but it shows signs of use. There are scratches and minor imperfections.
