Sara Makkenze – Mangold

When I first came into contact with Herman Ilgen 10 years ago, his INSA-Method immediately attracted my interest. The influence of behavior on (nonverbal) communication and the influence of nonverbal communication on behavior is something I have been focusing on all my life. I have therefore been involved in the INSA research from the beginning. Furthermore I have been teaching at Leiden University since I finished my Master in Social and Organizational Psychology there. I specifically teach and train in the domain of communication and psychology with the goal of making people conscious of the effects of their behavior, so they may adjust it if they are open to do this. I also worked independently for several consultancy companies.
