Garrett's Interactive Theory Of Speech Production

1065 Words 4 Pages
When looking at speech production, one of the most important ongoing arguments is whether the processes involved are discrete or interactive. This argument refers to whether or not there is interaction between the levels of processing. For example, whether the processing of one level can influence the processing of another. If there is no interaction and information simply feeds forward through the levels, then this can be considered discrete processing. However, if there seems to be interaction between the levels, such as feedback, this can be considered interactive processing. These two ways of processing can be analysed and argued through the various speech errors we produce. Here, I will be analysing the speech errors in the sentence below …show more content…
The first error in this sentence occurs in the sound level of Garrett’s model as it concerns the positioning of the initial sounds of a syllable. The error ‘par cark’ is known as a spoonerism. A spoonerism is a word-initial onset exchange. Here the /p/ and /k/ have exchanged. This error would be evidence for discrete processing as the error is only occurring at one level. There is no evidence for any interaction between levels and there is nothing to suggest that feedback from another level has affected the error. The evidence for this error therefore supports Garrett’s …show more content…
Dell (1986) suggests that units are activated at each level of processing and the unit which is most highly activated will be slotted into a frame at each level. The activated units also spread their activation to its connected units both downwards and upwards. It could be argued here that the unit ‘park’ has been activated and has spread its activation to its semantic neighbour ‘garden’. Thus resulting in both units becoming activated and slotted into the syntactic frame. Harley puts forward the idea that the feedback between the levels ‘gives rise to lexical bias and similarity constraints’ (Harley 2014: 423). Harley’s point would support Dell’s model in reference to this error as similarity effect is
