Volume 1 of the Handbook of Neuropsychology contains 17 chapters divided into two sections. "Section 1: Introduction" presents the views of various authors discussing practical and theoretical issues of general interest and two chapters cover clinical evaluation in a novel and comprehensive fashion. A feature of Neuropsychology in recent years, the spectacular comeback of single case studies, is covered in a chapter on statistical approaches comparing statistical procedures appropriate for groups to that of single cases. Through two different points of view the important topic of Hemispheric specialization is examined and several chapters deal with the application of theoretical models to neuropsychology in its daily and research aspects. "Section 2: Attention" examines selective attention with chapters on visuo/spatial attentional phenomena and the temporal aspects of attention. The phenomenon of failure to orient, neglect and neglect related phenomena are dealt with in a separate chapter as is the anatomy and the neurophysiological properties of the circuits whose lesion produces neglect deficits in primates.
