The Mother-Child Home Program was planned as a home-based, two-year cognitive intervention method. Women with varied incomes and education, both volunteer and paid, made 30-minute home visits twice weekly to help mothers become cognitive trainers of their own toddlers (starting at age two). Mother-child verbal interaction was stimulated with gifts of attractive, self-motivating materials, chosen because of their suitability to the child's developmental level, and their potential for verbal interaction when used in play between mother and child. Interveners, called Toy Demonstrators, guided mothers to use the Verbal Interaction Stimulus Materials (VISM) in an atmosphere that was spontaneous, relaxed, and most importantly, nondidactic. Most low income mothers seemed to welcome any kind of cognitive intervention designed to help their children do well in school. Other mothers were resistant, yet appeared cooperative because it was difficult for them to make verbal refusals. A brief appendix highlights several Toy Demonstrators' descriptions of successful mother-involvement techniques. (DB)
