The increase of intellectual performance efficiency in students and adult professionals involved in intellectual work on a regular basis is a very topical issue in both science and practice. We investigated patterns of metacognitive regulation typically used by our subjects during their performance of intellectual work of various kinds. The objective of our research was to determine if the patterns we found in our previous study manifest themselves in another sample and whether or not they can be divided into 2 groups: productive and unproductive.
