The concept of language acquisition by deaf people have a dual path approach, first studies originating from theories that characterize this acquisition in the context of communication and studies that describe the acquisition as a process strictly linguistic, communicative and unrelated variables related to the specific parameters of the Spanish language, analyzes and compares against oral language Castilian speakers or listeners. The aim of this review is to analyze the findings of the evidence about lexical access in sign language and its description in deaf users of this language. We performed a critical analysis of the theories and studies but little evidence was not made in the analysis of the process of lexical access in sign language. This search reveals the little theory and research in the description of the process of lexical access in sign language and calls for research in the area to generate studies on sign language to ensure quality interdisciplinary actions in the management of sign language and its potential pitfalls.
