I am trying to access the full article through my library system but it will take some time. It is worth noting that my goal is for light to make me sneeze, if and only if I already feel like sneezing. This is different from ACHOO syndrome as generally described; so I am unsure whether my technique uses the same biological mechanism.
EDIT: Until reading your post I had not considered the possibility that I may be a carrier who had not yet expressed this trait. I thought that I would be able to acquire it through conditioning regardless. Lack of a response from my family suggests that this is an acquired trait for me.
UPDATE: Indeed, http://www.ncbi.nlm.nih.gov/pubmed/7673597 was about to discriminate between this hypotheses. I have the article and it states that 39.3% of those affected reported no family history of photic sneezing. From this and other data they conclude that ”… in approximately 25% of cases the [photic sneeze response] may be inherited in an autosomal dominant manner, but the majority of cases appear to be related to environmental influences.” They did not identify any causal environmental factors for the formation of this response, but that it is primarily acquired is good news for anyone interested in trying it.
