we have here a very considerable achievement ... particularly welcome ... Susanna Millar, for her work in the field, has deserved a celebratory festschrift; the only problem is that this volume will be a very difficult act to follow! * Christopher Spencer, University of Sheffield, The British Journal of Visual Impairment, 1995 * The book is a 'must' for researchers probing into the complexities of how the young human child, when deprived of the sense of sight, comprehends and represents space. It will be obligatory reading, too, for those whose investigations have been based on the notion of the primacy of vision. It is a masterly review of the relevant literature, capped by the expounding of a genuinely new and testable model. * Michael Tobin, Research Centre for Education of the Visually Handicapped, Perception, 1998, volume 27 * '...The book has many attractive ingredients. It is concerned with important theoretical issues. It draws upon an extensive and varied literature...It really is quite rare to encounter work which maintains a clear focus on such significant representational issues while, at the same time, attempting to apply the ideas directly, in this case to the techniques which might be used to compensate for the absence of sight...the wealth of data which the book provides is sufficient to make it valuable to its target audeince of psychologists, researchers in spatial representation, specialists working with the blind and the merely curious.' * Rob Ellis, Dept. of Psychology, Univ. of Plymouth *
