No standard values
There are no standards for the time required to reliably recognise a word segment.
This value is individual and varies between 50 and 500 milliseconds.
Trainable
This ability is one of the decisive factors for the reading speed that a reader can achieve. It can be improved very well through simple training.
Common error
Too short fixation intervals are one of the most common causes of reading disorders. As a result, the segments are not fully recognised and the reader fills in the missing information by guessing.
