For the experiment, Slobin modified an existing method—the task-comparison research methods where he provided the "design for the testing of 48 children (three girls and three boys in each of the eight age groups: 2;0, 2;4, 2;8, 3;0, 3;4, 3;8, 4;0, 4;4). In the task, each child was presented with a pair of toy animals or dolls and was asked to demonstrate an action of one object upon the other. For example: "Here's a camel. Let's think of a little story about him. How about, 'the camel is sleeping'. Can you show me what that would be like?" Over the ten-day period, each child received three different kinds of the test. There were 18 verbs and 18 forms of the test allowing for permutations of word order and case inflections. The results is presented in table forms showing percentages of first-choice in all four languages by order of choice, whether it is Subject-Object, Noun-Object, etc. The most significant data gathered from the results was that Turkish children perform extremely accurate on all the grammatical sentences, even from the youngest age. Overall, the Turkish subjects perform better than children learning other languages. "The English and Italian children in the younger ages perform at an intermediate level and the Serbo-Croatian children had the greatest difficulty."
