 Personifications tend to co-occur with grapheme-color synesthesia and share many of the characteristics that are definitional of synesthesia, such as being consistent over considerable time intervals and generating concurrents automatically .To demonstrate that personifications are automatically evoked, Simner and Holenstein used a modified Stroop paradigm, in which a mismatch between the evoked personality and the gender leads to slower reaction times.To test this, synesthete AP was asked to report whether common names, like Brian or Betsy were male or female names.
