It seems like only a few short months since we co-edited The Corsini Encyclopedia of Psychology and Behavioral Science. We have now compiled the materials for the “Concise” edi- tion of these volumes. In this edition, we have asked previ- ous authors to update their material to reflect the most re- cent ideas and research findings on their topics. This edition also contains new entries because the fields of psychology and neuroscience continue to flourish. Although each entry is shorter than those of the four volume Encyclopedia, we trust they are thorough enough to be informative to the reader. Numerous authors have referred to other publica- tions relevant to their entries.
