This book was first published in 1977. In bringing together psychology and urban design there is always the risk of alienating specialists in both fields. The psychologist may resent the failure to observe the strict rigour of his subject, whilst the urban designer may be put off by such rigour as exists. In such a book as this, it is only possible briefly to refer to the research that has prompted these ideas. The author hopes the references will be taken up by those who have an intrinsic interest in the psychological theory. The aim is to apply different aspects of psychology to the problem of urban design in an attempt to probe into how it is that some towns and cities offer pleasure in many dimensions.
