Visual Form Constancy

What is Visual Form Constancy

Visual Form Constancy is the ability to mentally manipulate forms and visualise the resulting outcomes. Those with poor visual form constancy may struggle to identify objects when displayed in a different orientation i.e. upside down or viewed from a different perspective.  

Signs of poor visual form constancy may include:

- poor recognition of letters when presented in a different style of print (size, font colour)
- difficulties reading, where the individual may not recognise words as they are presented on a different medium  ie written on a whiteboard or in a book
- difficulties in identifying errors
- issues with recognition when looking at an angle/different orientation
- confusion between the letters “p,q and g” and “o,b and d”
