Question 52

Context

A cognitive ergonomist investigated whether visual-spatial manual dexterity was affected by the color temperature of ambient overhead lighting. They used an independent groups design.

  • Condition A: Participants were given 3 minutes to assemble a 25-piece micro-mechanic model under warm overhead lighting (2700 K). Their completed assembly was then assessed using a 5-point precision alignment rubric.
  • Condition B: Participants were given the same 3 minutes to assemble the same 25-piece micro-mechanic model under cool overhead lighting (6500 K). Their completed assembly was then assessed using the same 5-point precision alignment rubric.

Task

Explain why it would be appropriate for this researcher to use a pilot study. In your answer you must refer to details of the experiment described above.
