Are there any studies that report the effect of using/not using visual cues to engage users and retain user attention? In my own application I have offer listings with a representative graphical representation shown alongside a snippet of teaser text as show below
Intuitively I feel that the visual cue goes a long way to persuading the user to take things a step further and examine the offer in detail. However, this is just my own, unverified, intuition.
I'd be most obliged for any views on how/whether this works in practice.
In the sample screenshot above I have used black images. Quite apart from size considerations I found that it is difficult to display colored images that are "uniform" - i.e. do not "guide" UX because some of the images shout "Click Me!", "CLICK ME", "click me!" louder than the others - another issue on which I would like some views.
