Synopsis Psychologists in their attempt to study the behaviour of the general population did not neglect the tribal people in their studies. They found it very difficult to collect information from the tribal people. However there were some studies made very recently among the tribal groups. The data obtained from these tribal groups enabled us to compare their behaviour with other civilized and advanced groups. In this book emphasis has been laid upon school and college students of the tribal groups for assessing their interests and motivation. The behavioural patterns of different tribal groups and their social and their intelligence levels are assessed here. This book would be very much useful to those who are interested in knowing the behavioural patterns and the life styles of the tribal people in India.
