Researchers in this study found evidence that bodily and facial expressions may compete for attention from the other person during social interactions. The expressions influence the  brain responses (event related potentials) of the other person.

In this study evoked response potentials were examined in adult and older adult subjects. The researchers found that older adults were slower to modify ERP amplitude response to repetitive stimuli.
