For centuries the "treatment" of mentally disturbed individuals was quite simple. They were accused of collusion with evil spirits, hunted, and persecuted. The last "witch" was killed as late as 1782 in Switzerland. Mentally disturbed people did not fare much better even when the witchhunting days were gone. John Christian Reil gave the following description of mental pa tients at the crossroads of the fifteenth and sixteenth centuries: We incarcerate these miserable creatures as if they were criminals in abandoned jails, near to the lairs of owls in barren canyons beyond the city gates, or in damp dungeons of prisons, where never a pitying look of a humanitarian penetrates; and we let them, in chains, rot in their own excrement. Their fetters have eaten off the flesh of their bones, and their emaciated pale faces look expectantly toward the graves which will end their misery and cover up our shamefulness. (1803) The great reforms introduced by Philippe Pinel at Bicetre in 1793 augured the beginning of a new approach. Pinel ascribed the "sick role," and called for compas sion and help. One does not need to know much about those he wants to hurt, but one must know a lot in order to help. Pinel's reform was followed by a rapid develop ment in research of causes, symptoms, and remedies of mental disorders. There are two main prerequisites for planning a treatment strategy.

Educational psychology is a broad field characterized by the study of individuals in educational settings and how they develop and learn. It incorporates information from such sub-disciplines such as developmental psychology, human development across the life span, curriculum and instruction, motivation, and measurement and assessment. Neil Salkind has mined the rich and extensive backlist of SAGE education and psychology journals to pull together a collection of almost 100 articles to be the definitive research resource on education psychology. Section One: Human Growth and Development focuses on the processes involved in human growth and development including ages and stages of development, different theoretical perspectives and the role and effectiveness of early intervention among other topics. Section Two: Cognition, Learning and Instruction concentrates on the mechanisms, through which individuals learn and retain information. Section Three: Motivation explores why individuals seek out goals and what the mechanisms are that characterize this search as it relates to learning. Section Four: Measurement, Assessment and Statistics looks at the topics that are critical to understanding individual differences, the growth in the use of computers as assessment tools, qualitative and quantitative methods, statistical techniques and evaluation.
