Clark & Mayer demonstrated that graphics must be present next to the text mentioned, as distance generates increased
cognitive load, to the already knowledge - limited
capacity of active memory, with the direct consequence of dissuading the learner from active learning.
The act of suppressing potentially threatening information and keeping it out of awareness requires the allocation and maintenance of
cognitive resources (Ochsner & Gross, 2005), which can be disrupted and depleted under conditions of elevated
cognitive load or intense emotion (Caldwell, Krug, Carter, & Minzenberg, in press; Edelstein & Gillath, 2008; Mikulincer, Dolev, & Shaver, 2004), resulting in the breakdown of attentional control and diminished
capacity for self - reflection and mindful awareness.
