Skilled speechreading: a single-case study.

In a case study the cognitive characteristics of a skilled visual speechreader (SJ) was examined and compared to a group. SJ is a 56 year old woman, skilled in visual speechreading. She differs from most of the 119 individuals in the control group, as she uses a particular speechreading strategy in which she attempts to repeat overtly each spoken word as soon as it has been uttered, and to summarize and fill in missing pieces of information whenever it is possible (e.g., during pauses) during the conversation. SJ outperformed the control group on three types of tasks; a reading span task, performance in the asymptote level in the serial position curve, and verbal inference-making. SJ's results were discussed with respect to (a) how they related to the general case (i.e., models based on group-data) and to (b) her speechreading strategy. From a clinical perspective it was suggested that it might be possible to practice the strategy as such, but any possible improvement is dependent on the individual's capability to process information in this way.
