In addition to the many positive effects on the life quality,\nsmartphones have been observed also to cause some negative effects on \ncognitive performances. For example, just hearing a notification sound have \nbeen observed to decrease attention and sending messages while in class \nlowering learning outcomes. Even just the mere presence of smartphone has\nbeen observed to lower working memory capacity, even though the results \nhaven\u2019t been replicated in some studies. Contradictory results could be \nexplained by some unknown variables that have not been controlled in the \nstudies. Because of this research gap and potentially huge implications of this \neffect, this study attempted to replicate the effect of mere presence of \nsmartphone on working memory capacity and point out potential causes for the \neffect. Theoretical framework to explain the effect is presented. In the \nframework the working memory capacity is defined as one\u2019s own ability to \ncontrol attention to maintain relevant information. Orienting attention is \ndefined to be driven by selection and reward history, goal-driven attention, and \nstimulus-driven attention. Subjective importance of one\u2019s own smartphone is \nidentified as potential cause of the effect and it is conceptualized with online \nvigilance construct. Experimental within-group laboratory study was \nconducted in the study. Quantitative methods, such as hierarchical linear \nregression, were used to analyze the experimental dataset. No effect of \nsmartphones presence was observed on the working memory capacity, but \nproblem with the shortened AOspan (Automated operation span task) task is \nlikely explanation of the results. The task was too easy for the participants, so\nsignificant part of the participants received perfect score on the task. The \nproblem with the task was surprising, since the shortened version of the task \nhad been validated in previous study. Expected connection between online \nvigilance and value-driven attention was observed which gives support to the \ntheoretical framework.
