Matching Familiar Figures Test (MFF)
Matching Familiar Figures Test (MFF) is a visual assessment which requires an individual to choose the figure (there are six choices) which correctly matches a specified sample. It measures the decision-making speed by recording the response time, the frequency of correct matches, and the number of errors. The participants who quickly respond and commit a number of errors have an impulsive decision making style while those who respond slowly but accurately have a reflective decision style. MFF was originally published by Jerome Kagan, an American psychologist, in 1966.
