This systematic review aimed to determine the current understanding of the role of cognitive load in paramedical contexts.<b>Methods:</b> To do this, five databases were searched (Elsevier Embase, ProQuest Psychology, CINAHL, Ovid Medline, and Ovid PsychINFO) using synonyms of cognitive load and paramedical contexts.
