Take a look at Laura watching one of her favourite TV ads. How can we tell she’s enjoying it?
She’s smiling, not just in a quick and fleeting way, but with a sustained and relaxed smile on her lips.
When people are experiencing pleasure we see the eyes widen. Laura is looking at the screen with wide open eyes – she wants to take in as much information as she can.
She’s looking intently at the screen, something we can see from the focus in her eyes. This is not something which she is just mildly interested in. It has her full attention.
