Schemata (Cont.)
• To process information with the use of a schema is to determine which model best fits the incoming information.– Does the animal at a distance more closely resemble a dog or a
cat?
• Features of schemata.– constants (all birds have wings) and – variables (chairs can have between 1 and 4 legs);
• Aimed at evaluating how well they fit to the data being processed– Does the patient’s chest pain seem more like a case of
heartburn or might he be having a heart attack?
