A cognitive psychologist wanted to investigate the impact of auditory distractions on short-term memory retrieval. She randomly assigned 30 participants to two conditions. In Condition A, participants memorized a list of 20 high-frequency nouns in complete silence. In Condition B, participants memorized the same list of 20 nouns while listening to loud energetic pop music (played at 75 dB). Retrieval performance was measured by the number of words correctly recalled after a two-minute study period.
Write an appropriate operationalised directional hypothesis for this experiment.
