Communication and Symbolic Behavior Scales Manual

One of the best measures of early communication, the norm-referenced, standardized CSBS uses parent interviews and naturalistic sampling procedures to collect crucial information--not just on language skills, but on often-overlooked communicative behaviors like communicative funcions, gestures, rate of communicating, positive affect, and gaze shifts. CSBS is compatible with most developmental curricula in use today and comes packaged with everything professionals need to conduct and score assessments for children 8-24 months (or up to 72 months if developmental delays are present):Wetherby, Amy M. is the author of 'Communication and Symbolic Behavior Scales Manual', published 2003 under ISBN 9781557666673 and ISBN 1557666679.
