A General Model for Simple and Complex Addition.
Cormier, Pierre A.; And Others
A sample of 24 subjects was presented with 800 addition problems to test a general model of simple and complex addition. According to this model, an addition problem is encoded and verified by column, with specific addition strategies determined by the size of the problem. Two hundred problems each of the following four types were presented: (1) two single-digit addends (type I); (2) one single- and one double-digit addend (type II); (3) two double-digit addends (type III); and (4) three single-digit addends (type IV). Multiple regression analyses applied to average reaction time data identified the specific strategies for each type of problem, with multiple r's ranging between .80 and .90, and supported a self-terminating strategy for complex problems. A discussion of the general model is offered.
