Clinical Assessment, Computerized Methods and Instrumentation constitute the seventh volume of the Computer in Psychology series. This book contains eighteen contributions from the workshop "Computers in Psychology", held in September 1999 at the University of Utrecht. The first section of this book contains contributions concerning clinical assessment. Aspects such as short term memory, spatial memory, counseling skills and play therapy are described, as well as computer assisted observational analysis using eye blinks. In the second section, a series of computer programs supporting decision making in psychotherapy and diagnostics, in clinical and other settings, is described. The last section deals with real-time aspects of computers and computer controlled experimental setups.
