Primary use / Purpose: 

The Test of Genuineness (TOG-R) measures the consistency of synaesthetes reports on linkage between sounds and colours.


The Test of Genuineness (TOG-R) was created in 1987, however revisions such as the introduction of colour swatches and computerisation of the measure were needed, hence the TOG-R. Synaesthesia is a condition found more frequently among those with autism spectrum disorders. This measure may further our understanding of this connection.


Validity is discussed in Asher, Aitken, Farooqi, Kurmani and Baron-Cohen (2006)
