Dialect Test
The Dialect Test was created by A.J. Ellis in February 1879, and was used in the fieldwork for his work "On Early English Pronunciation". It stands as one of the earliest methods of identifying vowel sounds and features of speech. The aim was to capture the main vowel sounds of an individual dialect by listening to the reading of a short passage. All the categories of West Saxon words and vowels were included in the test so that comparisons could be made with the historic West Saxon speech as well as with various other dialects.
Paradox psychology
Even though the method was documented to be successful when working with treatment-resistance, paradoxical interventions lost favor in the late 1980s and '90s. This was due to the fact that the psychology field desired to present itself as science oriented, and pushed for 'evidence based' approaches. Since the underlying theory and mechanism for the paradoxical approach had remained an 'unsolved mystery', there was no way to promote the method in a concise and logical manner.
