Several studies showed a Simon effect when two participants sit close to each other and perform one of the two halves of a two-choice RT task. That is, each participant perform a go-no go task. A Simon effect emerges, which instead is absent when the same go-nogo tasks are performed individually. Hence the terms were introduced of "social Simon…

Naming a picture of a dog primes the subsequent naming of a picture of a dog (repetition priming) and interferes with the subsequent naming of a picture of a cat (semantic interference). Behavioral studies suggest that these effects derive from persistent changes in the way that words are activated and selected for production, and some have…

The debate between Simulation-Theory (ST) and Theory-Theory (TT) provides the dominant theoretical framework for research on "theory of mind" (ToM). Behavioural research has failed to provide clear methods for discriminating between these theories, but a number of recent studies have claimed that neuroimaging methods do allow key predictions of ST…
