Perner et al. (2002) distinguished between switching and coordinating or confronting perspectives.
Clearly, children can take different perspectives at different times, thereby switching. This can be
externally induced. Most straightforward, moving to a new location alters one’s visual perspective.
Verbal perspective switches can be induced by other speakers using an alternative name. Plausibly,children do this without noticing that a different name has been used. However, to deliberately switch perspectives, one must be aware that one is doing so. This requires understanding that there are perspectives and that, therefore, perspective differences are possible. This is the ability that is taken to be demonstrated by the False Belief and Alternative Naming tasks.
