Sounds in the Classroom: Auditory Context-Dependent Memory in School-Aged Children

AbstractContext-dependent memory (CDM) is the effect whereby information is retrieved more accurately in the presence of the contextual information that was present during encoding than in the absence of that contextual information. Most previous CDM experiments have focused on spatial location, but contexts such as sights, smells, and sounds have also been shown to be effective mnemonic cues, although the research is more limited. In relation to auditory contexts, much of the previous research has focused on music and on adults. We were interested in determining whether auditory CDM effects could be found in a classroom setting in school-aged children using background noises. Across two experiments we found that the reinstatement of the auditory context improved memory performance for 2nd, 3rd, and 5th grade students. Sounds, not just musical pieces, are stored in memory and can be effective contextual mnemonic cues. Further, (auditory) CDM effects can be found in young children. Teachers should be aware of the influence of contextual auditory cues in the classroom setting, and how this information is stored along with the focus of the teaching lesson.
