This is a a collection of essays pioneering new concepts in cross-cultural psychology based on the work of Philip E.Vernon, a pioneer of rigorous theory building and careful methodology. It includes empirical studies on a wide-ranging geographical background. Kline's lengthy and important chapter on measurement is a major advance in the understanding of this field, as is the chapter by Triandis on pluralist concepts of research. The possibilities and complexities of measurement in the field are further explored in the chapters by Irvine, Verma and Mallick. The empirical excitements of cross-cultural research are demonstrated in a number of chapters including those by Berry on psychological acculturation and social change among aboriginals in Canada, Shand and her colleagues on infant care in Japan and Bagley on perceptual styles in children from a variety of ethnic groups in Britain and Canada and in children in India, Jamaica and Japan.
