- Minority influence
- Moscovici, Lage and Naffrechoux (1969).
- Social influence is not limited to a one-directional influence of the majority on the minority, but also a minority can also influence the majority.
- Similar to Asch experiment, but with minority of confederate.
- Task and experimental conditions:
- To name aloud the colour of slides.
- 4 participants, 2 confederates.
- Confederates were instructed to state that the slides were green...
- On every of the 36 trials (consistent condition).
- On only 24/36 trials (inconsistent condition).
- Control condition: 6 participants, no confederates.
- Confederates were instructed to state that the slides were green...
- Results:
- Consistent condition:
- 32% of the participants gave at least 1 'green' response.
- 8.42% of all responses given were 'green.'
- Inconsistent condition:
- No significant influence.
- 1.25% 'green' responses.
- Control condition:
- 0.25% 'green' responses.
- There was also a shift in the threshold for perception 'green' particularly for participants who hadn't conformed to the minority.
- Consistent condition:
- Some factors that affect minority influence:
- Consistency of the behavioural style is crucial for the minority to have influence:
- The minority's responses must be highly consistent over time (diachronic consistency) and with each other (inter-individual consistency, synchronic consistency).
- The majority must be aware of this consistency.
- The majority must believe that the minority's consistency indicates confidence in the accuracy of their opinion.
- Consistency of the behavioural style is crucial for the minority to have influence:
- Is it really necessary for the minority to be consistent?
- The behavioural style must not be too rigid.
- When the minority adopts a flexible behavioural style by linking its responses to another property of the stimulus that has to be judged, it achieves more influence than what it does not.

- Task and experimental conditions:
- Colour perception task, minority confederates responded in one of five ways:
- 28 repetitious 'green' response.
- 28 repetitious 'green-blue' response.
- 'Green-blue' response to the 14 brightest slides, 'green' to the 14 dimmest slides.
- 'Green' response to the 14 brightest slides, 'green-blue' to the 14 dimmest slides.
- 14 'green-blue' and 14 'green' responses randomly paired with slides.
