A study was conducted to measure the degree to which groups of infants could generalize color across objects of different forms and sizes and generalize from across objects of different color and sizes and to see whether color or form would dominate in their generalizations. Ss were 8-13-month-old Caucasian infants. All tests had 16 Ss except the first, which had 24. All test toys were red or blue. Tests were counterbalanced in color or form of habituated and choice objects, in position of choice objects, and in age and sex of Ss. Ss were given five tests in which they were given a series of toys with similar properties for periods of two minutes each for Test 1 and three minutes each for Tests 2-5 (for a total of six minutes for each test), after which they were given a choice between a similar toy and a novel one. Ss chose the novel toy in all tests significantly above chance level, indicating an ability to generalize these forms, colors, and sizes. They generalized form more than color and in preference to color. (Author/KM)
