This work pertaining to gerontological psychology was intended as a reference book for French-speaking students and researchers working in the field of gerontology. The authors present gerontology under various themes, such as socio-demography, physical changes, sexuality, intelligence and memory, personality, psychological well-being, life transitions, loneliness, depression, suicide and organic brain pathologies. All the themes are structured identically. The authors very carefully define and delimit the subject, and then discuss it in terms of the aging process in its psychosocial context. The main themes are very well chosen. Furthermore, the authors took great care in treating the issue from various angles, namely from a physical, cognitive, psychic and social perspective. The clarity and lightness of the text make it a good introduction which will be greatly appreciated by its readers.
