It looks like ritualistic, repetitive behavior could reduce agitation in patients suffering from obsessive compulsive disorder (OCD), according to a study at the Tel Aviv University.
The research was carried out by
Prof. David Eilam and his graduate student
Hila Keren of the
Department of Zoology at
the George S. Wise Faculty of Life Sciences.
They found that repetitive behavior in general and especially ritualistic-like behavior is not only a human phenomenon but also one in the animal world. They concluded that ritualistic behavior in both humans and animals developed as a way to induce calm and manage stress caused by unpredictability and uncontrollability heightening our belief that we are in control of a situation that is otherwise out of our hands.
Pursued in collaboration with Prof. Pascal Boyer of Washington University and Dr. Joel Mort of the U.S. Air Force Research Laboratory, the research has been published in
Neuroscience and Biobehavioral Reviews.
Heads or tails? Almost every human and animal activity can be divided into three parts, Prof. Eilam explains preparatory, functional, and confirmatory. The functional aspect is defined by the specific actions that must occur in order to complete a task. But the preparatory and confirmatory actions, dubbed head and tail actions by the researchers, are not strictly required in order to get the job done. We complete them both before and after the central task, but they are not necessarily related to it. Individuals complete different head and tail activities for every task.
