We conducted three experiments (Online, Lab, and VR) using Random Dot Kinematogram (RDK) tasks to test perceptual accuracy and confidence in individuals with CCD. tl;dr: Those with CCD showed normal perceptual accuracy, but poor metacognitive sensitivity.

We suggest that the absence of a CC is causing a nonsystematic computational failure. This would explain why those with CCD struggle to notice social and reasoning errors in classic neuropsych tests, and suggests a crucial role of the CC in metacognition code/data: github.com/Brain-Develo...

This was work conducted over 5 years (started during my postdoc!) and would not have happened without the participation and support of wonderful charities such as AusDoCC (ausdocc.org.au) and the NoDCC (nodcc.org)
