Abstract

A study was carried out to examine the effects of types of acoustical distortion on lexical access. The study aimed to replicate and extend the claims of authors Aydelott and Bates (2004) regarding the effects of acoustical distortion on lexical access. It was expected that for intact sentence contexts, reaction times to target in congruent contexts would be faster compared to reaction times in a neutral context, whereas those in an incongruent context would be slower. Furthermore, if reaction times differ depending on the type of distortion then the pattern suggest how priming may differ in lexical access for different types of distortion. The analysis also revealed that different types of distortion did affect lexical access to different degrees. It concluded that the distortions due to low-pass filtering and signal-to-noise ratio (SNR) produced a release from inhibition and significant decrease, while time compression significantly reduced facilitation and increased inhibition.
