Deficit Theory
English Language: AQA A Level, topic 3.1.4
Deficit Theory - Origins from Otto Jespersen
The deficit theory essentially states that women’s language is weak or contains weak traits. The theory originates from Otto Jespersen’s book published in 1922.

Otto Jespersen
- Jespersen investigated non-fluency features such as fillers and pauses.
- Jespersen’s research details that women speak without thinking and so use more non-fluency features (features which disrupt the fluency of speech).
- Jespersen’s research relies on evidence from literature and travellers. This means it is speculative and is often dismissed as folk linguistics.
- On the next slide, you will see how these sentences form a level 5 answer.

Moving up assessment bands (AO2)
- Level 3 - showing detailed knowledge:
- “Jespersen investigated non-fluency features such as fillers and pauses.”
- Level 4 - challenging this:
- “Jespersen’s research is disputed by Onnela who found that with masters students, there was a very similar MLU ( mean length of utterance - the average time span of a piece of speech).”
- Level 5 - evaluation:
- “Jespersen’s research relies on evidence from literature and travellers and thus is speculative and is often dismissed as folklinguistics.”

Onnela
- Onnela disputes Jespersen’s research.
- Onnela found that with masters students, there was a very similar MLU (mean length of utterance - the average time span of a piece of speech).
Deficit Theory - Robin Lakoff
The deficit model was popularised by Robin Lakoff in 1975. Robin Lakoff's research details a list of features of spoken language that make women’s language ‘weak’. These include:

A hypercorrect grammar

Over-apologising

Empty adjectives
- E.g. 'lovely', 'brilliant', 'luscious'.

Tag questions
- Adding something onto the end of a declarative sentence to make it interrogative – e.g. you’re going out tonight, aren’t you?

Overuse of intensifiers
- E.g. ‘so’.

Special lexicon
- Special lexicon for certain things, like colour.

Less swearing

Lacking a sense of humour
Deficit Theory - Robin Lakoff
The deficit theory essentially states that women’s language is weak or contains weak traits. The deficit model was popularised by Robin Lakoff in 1975.

Robin Lakoff findings
- Lakoff states that women have a hypercorrect grammar. An example of this is women avoiding double negatives.
- Lakoff also says that women lack a sense of humour.

Supporting study - Kira Hall
- Lakoff’s research has been built on by linguist Kira Hall, who found that phone sex workers often made use of Lakoff’s features to appear more feminine.

Challenge - O'Barr and Atkins
- Lakoff’s work has been challenged by O’Barr and Atkins, who looked at a courtroom and found that lower class men use Lakoff’s language features in court.
- O’Barr and Atkins' research implies that it is potentially not to do with gender, but to do with power.
- This is denoted as ‘powerless language’.
- In addition, Lakoff’s research is based purely on her own observations and not any linguistically rigorous testing.

Further challenge
- In 2017, research published by ‘Economic and Social Research Council’ discovered that there had been a 500% increase in the use of ‘fuck’ by women since the 1990s.
