One of environmental psychology's conspicuous failures to date has been to come to terms with the changing historical nature of man-environment relations. A possible way foward would be to take advantage of the placespecific wealth of material (pictorial and written) available to local historians, and to trace over several centuries some of the constants - and inconstants - of behaviour in, and perceptions of, that local environment. Considering its ever-growing popularity, the field of local history to date has been curiously unwilling to deviate very far from well-worn formulas all too often overly nostalgic in tone, uni-dimensional in their analysis of change, and above all unimaginative in format. Perceptions of historical time and change are central to the experience and building of place, and it is time to open up local history to these and other applicable elements of environmental psychology and the psychology of time and change. Entitled GUILDFORD TIMESCAPES A Celebration of Change l7O-l989 it could provide a useful starting point for a wider ranging workshop on temporal aspects of environmental psychology.
