Non-random Human Performance under Conditions of Lacking Information

Many researchers have investigated implicit and explicit aspects in human behaviors. The Sequence Learning (SL) paradigm is one of the approaches used to investigate these aspects. The learning performance in SL tasks has been broadly studied. However, the guessing phenomenon has not yet been investigated, although it plays important part in a variety of human behaviors. The SL paradigm was adapted for the purpose of the guessing phenomenon research and used as basis for experimental design. The results show that human performance is non-random under conditions of lacking information, and both implicit and explicit aspects are found under these conditions. It further appears that under these conditions implicit knowledge is related not only to sequence learning itself, but also is assumed to indicate pre-knowledge of some kind playing crucial role.
