In this study we aim to test for the existence of learning signals underlying reward-learningthrough observation. Such signals would be expected to modify neural plasticity inregions of the brain involved in encoding stimulus-reward and stimulus-responserewardassociations, in order that associations learned through observation can beused to actively guide choice behaviour in future. We hypothesize that regions ofstriatum found to exhibit PE signaling during experiental learning, may also showsuch signals during OL. In addition, we will test for the presence of observational PEsin areas that do not exhibit simple experiental PE signaling, but that are specificallyinvolved in social cognitive processes. Given our previous results, a prime candidatearea for exhibiting such signals might be posterior STS.
