Context is critical.
As noted in previous attention research and a forthcoming book:
How Attention Works: Finding Your Way in a World Full of Distraction (The MIT Press) March 2019
“we gather only relevant information. We focus on one snippet of information and assume that everything else is stable and consistent with past experience.”
Our perceptual process attempts to focus on the most salient data or pixel set (e.g., bold type, color, relative position) to reduce IO.
As van der Stigchel’s quote above suggests, we can be mislead by ignoring related contextual attributes. Thus, we need to ask ourselves if the perceptual input is complete and consistent with our task objective. ]
Critical thinking skills can help.
Don’t be an IO victim.
