Dr. Elena investigated the effect of environmental temperature on short-term recall. She recruited 30 undergraduate students using a volunteer sampling technique and randomly allocated them to one of two experimental conditions. In Condition A, participants memorised and immediately recalled a list of 25 single-syllable nouns while sitting in a room maintained at a temperature of 16°C. In Condition B, participants memorised and immediately recalled the exact same list of 25 single-syllable nouns while sitting in a room maintained at a temperature of 28°C. Elena recorded the number of nouns correctly recalled by each participant.
