Assessment of auditory processing disorder in children using an adaptive filtered speech test (2013)
Objective: One type of test commonly used to assess auditory processing disorder (APD) is the 'filtered words test' (FWT), in which a monaural, low-redundancy speech sample is distorted by using filtering to modify its frequency content. One limitation of the various existing FWTs is that they are performed using a constant level of low-pass filtering, making them prone to ceiling and floor effects that compromise their efficiency and accuracy. A recently developed computer-based test, the University of Canterbury Adaptive Speech Test- Filtered Words (UCAST-FW), uses an adaptive procedure intended to improve the efficiency and sensitivity of the test over its constant-level counterparts. Design: The UCAST-FW was administered to school-aged children to investigate the ability of the test to distinguish between children with and without APD. Study sample: Fifteen children aged 7-13 diagnosed with APD, and an aged-matched control group of 10 children with no history of listening difficulties. Results: Data obtained demonstrates a significant difference between the UCAST-FW results obtained by children with APD and those with normal auditory processing. Conclusions: These findings provide evidence that the UCAST-FW may discriminate between children with and without APD with greater sensitivity than its constant-level counterparts. © 2013 British Society of Audiology, International Society of Audiology, and Nordic Audiological Society.

Communication Disorders, 2012)Objective: One type of test commonly used to examine auditory processing disorders (APD) is the low-pass filtered speech test (LPFST), of which there are various versions.

Tillard G; Cook KJ; Gerhard D; Keast L; McAuliffe M (2018)In summary, there is widespread support for the use of group discussion in reflective practice (Caty et al., 2015). The interaction with peers allows for the exchange and comparison of beliefs and behaviours, perspectives ...
