To avoid observer effect, subject was unaware she was participating in research. She was studied while sitting in her own home on her sofa, watching television. To avoid arousing suspicion, researcher posed as her long-term partner.
Stimulus 1: Guinness Cog
Subject was exposed to Guinness ad in premier spot during "Californication". She was either unaware of preceding hype or unmoved by such.
After observing between 5 and 6 seconds of advertisement, subject's attention turned to article on Amy Winehouse in gossip magazine.
When questioned about Guinness ad at conclusion of commercial break, subject denied that one had been aired. In the face of subject's superior skills of reason and argument, researcher was forced to acknowledge that said spot could not possibly have aired. (Subject has tutored logic at a tertiary level. She can build a Turing Machine; if he's perfectly honest, researcher doesn't quite understand what one is)
Stimulus 2: Artois- Pass it on
Subject seemed to be focused on this ad for about the first 10-12 seconds. She then began to relate a story about something that happened at work that day. When researcher attempted to draw her attention back to the TV, as he was quite curious to see the ad, he was immediately silenced so story could continue.
Perhaps consider introducing Amy Winehouse into Guinness ad?
Make "Pass it on" interactive by including a url where people can pass on their work stories. Either that or add more monkeys (subject likes monkeys).
Although the £10 million Guinness spot (which researcher, for the record, rather likes) failed to engage subject's attention, the much lower-budget ten second spot that followed it did raise a couple of chuckles. And that's all you can ask for really.
