The usage of external sources to enhance cognitive processing and decrease cognitive de-mands is called cognitive offloading, whose usage increased with the emergence of smartphones. This research aimed to replicate research conducted by Ferguson, McLean and Risko (2015) and explore the effects of the availability of internet search engines on knowledge assessment, willingness to answer, the correctness of answers, certainty in accuracy and expand previous knowledge of effects of availability of the internet on different kinds of knowledge (expert and general). The research was conducted on 81 undergraduate students of psychology (73 female and 8 male) on the Faculty of Humanities and Social Sciences in Rijeka, age between 18-23 (M = 19.66, SD = 1.21). The partici-pants were answering two lists of questions; psychology questions and trivia questions on computers during which one group could use the internet and the other one could not. The results show that when the internet was available, participants had greater willingness to answer based on their own knowledge, their answers were more correct, and they were more certain in accuracy of provided answers in comparison to participants who could not use the internet. Also, it has been shown that the internet had different effects on different types of knowledge (psychology and trivia) on willing-ness to answer, on false answers, and certainty in the accuracy of provided answers. Participants had a greater willingness to answer on psychology questions when they could use the internet, in com-parison to those who have not been able to use the internet, and that difference did not exist while answering trivia questions. It has been shown that participants on while answering psychology ques-tions had more false answers when they had possibility to use internet, instead while answering on trivia questions participants had more false answers when internet was not available for use in com-parison to when it was available for use. Also, in this research, there has not been a significant effect of internet availability on knowledge assessment. These findings are not completely in accordance with research provided by Ferguson et al. (2015) which suggests that the relationship between internet availableness, metacognitive assessment, and willingness to answer is more complex.
