Abstract

The current investigation examined patterns in episodes of word retrieval failure in a group of 30 adults who had suffered traumatic brain injury. The Test of Adolescent/Adult Word Finding (TAWF) was utilized to examine retrieval episode failure. Twenty-two of the 30 participants demonstrated a psychometrically-based word retrieval deficit on the TAWF. Using an episodes failure analysis (Hough, 2006), 15 of these 22 individuals with TBI were found to exhibit a fleeting pattern of retrieval failure involving numerous isolated word retrieval errors. The remaining seven of the 22 individuals showed an extended episode pattern of word retrieval failure characterized by many episodes of multiple consecutive word retrieval errors. The results will be discussed relative to the Interactive Activation Model and Node Structure Theory.
