VISUO-SPATIAL MENTAL PROCESSES AS REVEALED BY SPONTANEOUS EYE MOVEMENTS
Emanuele Primiceri · 1999
Traditional methods based on response times (RTs) led to the development of cognitive models of several mental activities. This is the case, for example, of mental rotation, which can be conceptualised as a gradual, time-consuming internal process performing angular transformations at a certain speed [1]. Yet, RTs alone cannot expose directly the instantaneous spatio-temporal evolution of mental rotation. By contrast, eye movements may contain just the spatio-temporal information that RTs do not afford. So far, however, although many insights have been gained from the analysis of eye movements in various mental tasks [2], efforts to reconstruct
