Identification and Hearsay

Under SCRE 801, prior identification by a witness is not hearsay under certain conditions. The declarant must testify at trial and be subject to cross-examination. The prior identification must actually be an identification too (i.e., reliable). How does a court determine if the witness actually identified the person?:
