Question 307

A researcher wanted to investigate whether linguistic background affects how people perceive and categorise physical colours.

She tested two distinct groups of adult participants:

  • Group A: Native English speakers (whose language has distinct words for 'blue' and 'green').
  • Group B: Native Himba speakers (whose language uses a single term, zoozu, for certain shades of blue and green combined).

Both groups were shown a series of 15 physical colour tiles ranging gradually from green to blue and asked to sort them into perceptual categories.

Identify the experimental design used in this investigation and explain one strength of using this experimental design.
