In a comparison of the melodies in the speech of Mandarin Chinese and Caucasian American mothers, striking similarities were found: (1) in the overall distribution and average structure of melodic contours; (2) in close contextual links to given forms of intuitive parental care; and (3) in a tendency to neglect lexical tones in favor of pitch…

Research relevant to planning and practice in the area of infant mental health is discussed in this paper. First, three examples of research approaches that reflect current attitudes are given. The first example represents those studies in which there is an effort to closely coordinate physiological and behavioral studies. The second example…

This report calls attention to those areas of research on aging in the behavioral and social sciences that have promise for both short-run and long-term. It looks at the societal context for aging, at processes of aging in the individual, and, finally, at the older person in the context of various social institutions. The societal context examines…

This review of research conducted on sex differences attempts to answer the following questions: (1) Do the sexes differ in their basic capacities for specific types of mental performance and occupational achievement?
