Psychological Testing History, Principles, and Applications,7th Edition by Robert J. Gregory
About the Author
Robert Gregory earned his Ph.D. in clinical psychology from the University of Minnesota where he absorbed a healthy respect for the value of empiricism in psychological testing. He taught at the University of Idaho for 23 years where he also developed a private practice in assessment. In his practice, he specialized in the evaluation of intellectual disability and cognitive impairment. His academic research centered on assessment topics such as subtle cognitive differences in left-handers, the impact of subclinical lead exposure on intelligence, the psychometric qualities of a wide variety of cognitive and personality tests, and meta-analysis. In one phase of his assessment career, he estimates evaluating more than 100 applicants for law enforcement positions. He has taught psychological assessment for 40 years. On 50 separate occasions, he has offered a course featuring one or another of the Wechsler scales (“Now do this one as quickly as you can, and be sure to tell me when you are finished”). He was professor of psychology at Wheaton College (Illinois) for seventeen years, including eight years as department chair, and five years as director of their doctoral program (Psy.D.) in clinical psychology. In his spare time he is an ambivalent jogger (motto: “Start slow and taper off”). He also does watercolors (motto: “Ability is over-rated”) which he stores in a secret compartment in his basement. He practices mindfulness-based meditation on a regular basis (seriously). He resides in the Seattle area and maintains an active interest in testing and clinical psychology. He is Professor Emeritus at Wheaton College (IL).
