Take part in a study about stammering and verbal reasoning skills

| 01.02.2019

A lower sixth form student is undertaking a study into stammering and is looking for people to take part.

What’s the study about?

As part of his Extended Project Qualification at Bedales School in Hampshire, Norpell Wilberforce is investigating if there’s a link between speech impediments and verbal reasoning skills.

Specifically, Norpell wants to see if there's a difference in how people who stammer put together and manipulate sentences, arrange grammar and make language-based/semantic decisions compared to people who don't stammer.

What does it involve?

Participants will be sent a series of tasks:

  • The first task will ask you to read passages of text and then answer true or false questions based on what you’ve read.
  • The second is a multiple choice-based task looking at grammar.
  • The third task involves unscrambling sentences.

Completing all the tests will take approximately twenty minutes.

The question papers will be sent to you via email and you will be asked to return them to Norpell.

Who can take part?

Norpell is looking for people aged 16+ who have English as their first language and who do not have any reading difficulties such as dyslexia, to take part. Ethical consent for the study has been provided by Norpell's supervisor.

If you’re interested, or would like further details, email Norpell at

We'll put the findings from the study up on the website when they're released, so stay tuned.
