This book presents varying assessment purposes, procedures and analytic approaches for professionals who are involved in making examinations and assessments of cognition in cases of congenital deafblindness in both children and adults.

People with congenital deafblindness often have hidden cognitive potential that those around them fail to detect. This can lead to missing out on communication, or not even having the opportunity to develop a tactile language. A professional assessment of the cognition may reveal latent abilities and with suitable strategies the person with congenital deafblindness can develop their full potential.

The book is aimed at professionals who are involved in making examinations and assessments of cognition in cases of congenital deafblindness in both children and adults. It is also an important contribution to further research in this area.
