Participants in a study by Bransford and Johnson (1972) that was discussed in class were given a memory test after being allocated at random to one of five distinct conditions. This is an example of a matched group factorial design.
By pairing together comparable subjects or groups, the matched group design (also known as the matched subjects design) allows for the observation of various experimental settings while simultaneously allowing for the control of individual differences.
Twin Studies, which pair participants based on their genetic make-up, such as identical vs. fraternal twins, are an excellent example of matched group designs. Matching is favorable because it increases the likelihood that our groups will begin the same, at least in terms of the factors we believe are important.
