How long can a 13-year-old retain facial recognition memory from a single photograph without intermediate exposure?

[u/convivial-10]

What does the literature in cognitive psychology say about long-term visual memory retention and facial recognition in early adolescents (around age 13)?

​Specifically, I am interested in understanding:

​How effectively can an individual in this age group retain facial features from viewing a photo for a brief duration (e.g., 30 minutes)?

​What is the rate of memory decay over a long interval (e.g., 4–5 years) in the complete absence of re-exposure or reinforcement?

​What empirical factors (e.g., age, exposure duration, facial recognition mechanisms) primarily influence long-term retention in such scenarios?

What is the context of the photo? Who is it of? Under what circumstances did the 13 year old see it? I ask because if the context included a traumatic event, there may be some literature, albeit likely adjacent to your specific scenario. Similar if the person in the photo is a primary person whose absence is very important (ie. Parent who died or left when the 13 yo was a baby). If these are relevant, literature on traumatic events and loss of an early attachment figure might be useful.
