Extends the examination of Green and Purohit (1976) who used matrices of 0s and 1s as stimuli in exploring recognition memory. It was found that with greater density (distance between elements) and lesser complexity (number of elements in the matrix), recognition performance improved. Results contradict an earlier finding of Green and Purohit, who found that more complicated matrices led to better performance. Implications for recognition memory and eye movements are discussed.
