"Saliency can be defined as how perceptually distinctive the information is in the context in which it is presented (Fishbein, Haygood, & Frieson, 1970; Sanfey & Hastie, 1998). Saliency can be affected by both bottom-up and top-down processing. Itti and Koch (2001) define visual saliency as a bottom up, stimulus-driven signal defined by the distinctness of an object from surrounding objects which can be modulated or overridden by top-down, user-driven factors. Saliency can be affected by bottom-up or preattentive processing based on features such as size, line orientation, form, sound levels, color hue and intensity (e.g. larger sizes and more intense colors can increase saliency). Additionally, saliency can be moderated by higher cognitive processes that are experience-based such as priming, recency, availability and expectancies (e.g. if searching for yellow squares in a bin of multicolored shapes then yellow and square items will be more salient than red triangles.)"

For today's project I collaborated with my mother. To give you a bit of an introduction, my mother is a computer programmer who decided to become a grad student in Psychology (go figure). The above is taken from a draft of her proposal outline. Since her research regards saliency, I asked her what would make my product more salient. She stated that "the key is to make it more distinct in the context." So, just like when one is "searching for yellow squares in a bin of multicolored shapes then yellow and square items will be more salient than red triangles", then a red octagonal shape will be more salient than square blue ones.
(PS, does anyone see the blue dots in the intersections of the white lines? Yeah, it's a fun optical illusion to play with...)
