Toward Explanation: The Simulation of Developmental Processes

The steps listed are summarized in Figure 19-1, which is based upon a simple hypothetical example of age simulation. The example chosen is noncontroversial in that it is unrelated to an existing theory or body of data. In our example, the researcher is interested in age changes in dart-throwing accuracy and finds in the literature that someone has studied this phenomenon carefully and obtained the age-change function designated in Figure 19-1 as the criterion age function. This criterion age function shows 20-year-old adults highest in accuracy, with 50-year-olds and lO-year-olds following in that order.
