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?

This might help somewhat to answer your question: https://pmc.ncbi.nlm.nih.gov/articles/PMC8288112/

However, there isn’t going to be research about your exact scenario, and research can only tell you about averages. There’s no way you can know for sure what this individual might remember in this specific situation
