Question 167

Study Description

A researcher wanted to investigate whether working memory performance is affected by the ambient temperature of the testing room.

The researcher recruited a stratified sample of 30 students from a college sixth form consisting of 120 Year 12 students and 180 Year 13 students.

Each participant was asked to memorize a list of 25 abstract nouns. They were given 3 minutes to study the list, followed by a 5-minute distractor task, after which they were asked to write down as many nouns as they could recover from memory.

There were two conditions in this independent groups design:

  • Condition A: 15 participants completed the task in a room maintained at a cool temperature of 17∘C17^\circ\text{C}17∘C.
  • Condition B: the other 15 participants completed the task in a room maintained at a warm temperature of 27∘C27^\circ\text{C}27∘C.

Each participant completed the study individually. The researcher recorded the number of nouns correctly recalled by each participant.

Write a suitable hypothesis for this study.
