We Smile Only for the Punchline

Here is a quick update to the posting about the kids swearing in the commercial.

Although the self-reported valence measure showed changes over time, when I measured electrical activity over the muscles involved in smiling, these participants smiled only after the punchline was delivered: "Ever run out of soap?"

Much formal analysis remains; however, this continues to be an interesting project.
