Lexical access, story re-telling and sequencing skills in adults who clutter and those who do not.

UNLABELLED: Cluttering is a rate-based disorder of fluency, the scope of whose diagnostic criteria currently remains unclear. This paper reports preliminary findings from a larger study which aims to determine whether cluttering can be associated with language disturbances as well as motor and rate based ones. Subtests from the Mt Wilga High Level Language Test (MWHLLT) were used to determine whether people who clutter (PWC) have word finding difficulties, and use significantly more maze behaviours compared to controls, during story re-telling and simple sequencing tasks. Independent t tests showed that PWC were significantly slower than control participants in lexical access and sentence completion tasks, but returned mixed findings when PWCs were required to name items within a semantic category. PWC produced significantly more maze behaviour than controls in a task where participants were required to explain how to undertake commonly performed actions, but no difference in use of maze behaviour was found between the two groups when retelling a story from memory. The implications of these findings are discussed.

OBJECTIVES

(a) To identify issues surrounding the difficulties in diagnosing cluttering, (b) to identify and describe previous accounts of a language component in cluttering, (c) to describe how difficulties with lexical access and maze behaviour might be associated with cluttering, (d) to describe how data from the current research inform our present understanding of theories on cluttering.
