Exercise 4.6

If the results from your tongue-twister experiment match those referred to in the textbook, then you should find that the greater the similarity between the key positions in terms of stress level and where they are in the word, the more likely it is that the elements will switch places. This matches the findings from spontaneous speech errors, supporting the idea that we plan the production of words in terms of 'slots' (positions in the word) and 'fillers' (the elements that fill those positions), and that an element specified for a particular slot in one word can - in an error - be placed in the corresponding slot in a different word.
