Christopher Fox and colleagues weighed in on this classic question with the help of volunteers (N = 207) from the Oregon Museum of Science and Industry in Portland, Oregon. Museum patrons ranging in age from 6 to 74 were given the opportunity to not just see science but to actually participate in the scientific process! They completed the full-length Berg Card Sorting Testing test, a classic test that measures executive function.
The correlation between all 128 trials and the first 64 was quite good for perseverative errors (r = + 0.77) and even better for the categories completed (r = .86) and total errors (r = .87). This study gave evidence that a shortened version of this test (64 cards) may be comparable to the classic, longer version. Thus, giving evidence that "Less is more"!For further information about this study, see Fox CJ, Mueller ST, Gray HM, Raber J, Piper BJ (2013) Evaluation of a short-form of the Berg Card Sorting Test.
