An Elaboration of Categories from SO Responses.

Category	Description	Quotes
Group and Social Contexts	SOs reported that their significant others’ difficulties had an impact on their behaviour in social contexts. This included, but was not limited to, avoiding social gatherings, coming across as disinterested or rude, and/or never introducing people or themselves to others. These were reported to be worse for many of the DPs when in group settings and presented with a number of faces at one time. This included at social gatherings and parties, or when watching television or film.	“When he meets people in the street he doesn’t introduce me” [SOF51] “Avoidant behaviour, does not engage on an emotional level, avoids physical contact and intimacy, and can come across as disinterested in others” [SOF46] “[she struggles to find me] when I am in a crowd” [SOM56] “Regularly identifies a face on TV as someone else and is 100% sure they have identified them correctly, but is wrong” [SOM54]
Importance of Context	SOs highlighted that seeing a person out of context made their significant others’ difficulties more prominent.	“I was aware that she seemed “poor” at recognising actors in different contexts” [SOM53] “He also has problems when meeting people out of context (e.g. a not so well known, but often seen neighbour, away from our ‘home streets’).” [SOF62] “It seems that the main difficulty is recognising people out of context. For example, when someone is known in the office or church, they are not immediately recognised in the street.” [SOM63]
Reliance on Extrafacial Information	SOs discussed the fact that their significant other often relies on extrafacial information to recognise a person, and that recognition fails when such information changes (including, but not limited to, one’s hairstyle, clothing or accessories).	“In the past, distinctive hair styles seem a valuable cue for recognition” [SOM53] “He cheered for the wrong person in a sports match because they had the same colour hair as me” [SOF19]
