This document summarizes a conference paper that explores identity construction processes in autobiographical narratives in relation to gender and race. It proposes a model to analyze how narrators use tense shifts between past narration and present reflection to construct and evaluate their evolving identity on individual, relational, and collective levels. The model is applied to analyses two autobiographical speeches - one by a former female slave and one by a Lebanese author - to examine how social constructs like gender and race are enacted through language in narratives.
