Originally published in 1973, this volume looks at the organisation of memory data in, what at the time was termed, ‘mental handicap’. The first part surveys recent work in this important area, giving a general account of experiments and findings. The second part reports a particular piece of research on memory in people with learning difficulties, then called ‘subnormal individuals’.Very much of its time, in terms of the terminology, this was an important book for anyone concerned with people with intellectual disabilities and for experimental psychologists involved with the processes of memory.
