May 2016: New paper
This study, published in the journal Cortex, investigates the perception of facial emotion by individuals with developmental prosopagnosia. A big thank you to all those who took part!
June 2015: The PI20 is published!
Our new self-report scale for the identification of prosopagnosic traits, the PI20, has been published at Royal Society Open Science. A big thank you to everyone who assisted in its construction and validation.
October 2014: New paper to be published in Cortex!
The following paper on memory for faces in developmental prosopagnosia will soon appear in Cortex. We would like to thank all those who participated.

August 2014: Is facial symmetry related to health?
In his article in The Conversation Rich discusses new research that casts doubt on the received story that facial symmetry is a attractive because it signals immuno-competence or 'good genes'.
April 2014: City University London celebrates World Autism Awareness Day
On the 2nd April, City University London's College Building and Social Science Building were lit up with blue lights to show support for World Autism Awareness Day. For more information see City-in-Blue.
March 2014: New evidence that difficulties with face recognition in
prosopagnosia are face-specific
There has been a longstanding debate about whether faces are processed by brain mechanisms specialised for faces or not. Research from Brad Duchine's lab has now found that, individuals with prosopagnosia, after training, are able to learn to discriminate between Greebles (novel objects that differ from one another in similar ways to faces) but remain impaired at recognising faces. This suggests that faces are processed in a specialized way compared to other objects, and that prosopagnosia is likely to be a face-specific difficulty. Rezlescu, C., Barton, J. S., Pitcher, D., & Duchaine, B. (2014). Normal acquisition of expertise with greebles in two cases of acquired prosopagnosia. PNAS.
September 2013: Here is an interesting facial illusion we came across recently. The images can appear to depict either frontal or profile views of faces. Most people find these percepts mutually exclusive - at any given time, you can see one or the other, but never both simultaneously. Illusions with this quality are referred to as 'bistable' and illustrate how our brains use previous experiences to impose an interpretation on the information flooding in from outside.
