Why do people do what they do? That question has intrigued me since I was an undergraduate student in psychology in the 1970s. I am currently a licensed psychologist and have provided behavioral skills training to parents in their homes (Yes, a psychologist who makes house calls) and school personnel for over three decades. You can read more about my approach to helping adults acquire the skills to change undesirable child behaviors in a free online book, "Punishment on Trial" at http://teachpsych.org/Resources/Documents/otrp/resources/cipani09.pdf . I hope you find my books informative and the real-life case examples entertaining, as my writing style hopes to achieve both objectives.
