Here's what grabs attention the most:

Loud noises
Slide 2
DANGER, FOOD, SEX, MOVEMENT, FACES, AND STORIES GET THE MOST ATTENTION...
It may not always be appropriate to use food, sex, or danger in your Web page or software application, but if you do they’ll get a lot of attention.
Use images of up-close faces.
Use stories as much as you can, even for what you think is factual information.
