Sounds, not just musical pieces, are stored in memory and can be effective contextual mnemonic cues.
Across two experiments we found that the reinstatement of the auditory context improved memory performance for 2 nd, 3 rd, and 5 th grade students. We were interested in determining whether auditory CDM effects could be found in a classroom setting in school-aged children using background noises.
In relation to auditory contexts, much of the previous research has focused on music and on adults. 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. Memories are reconstructed or replaced with incorrect information which that is often more consistent with a current image or perception.Context-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. Information already stored in memory interferes with learning new material.Īttempting to remember something in a different situation or internal state may negatively impact memory. Learning new material interferes with information already stored in memory. Storage of new information is disrupted most often due to injury.ĭamage to the hippocampus interferes with the formation of new memories often caused by brain injury, advanced aging, or Alzheimer’s disease. Information in memory deteriorates with the passage of time. When an experience doesn’t fit our view of the world or ourselves, we tend, unconsciously, to adjust it or to blot it out of memory altogether (Bremner & Marmar, 1998). Consequently, these changes become part of your memory of the event. Each time you tell someone the story of an incident, you may unconsciously make subtle changes in the details of the story. We may also reconstruct memories for social reasons or personal self-defense ( Feeney & Cassidy, 2003). Indeed, we are sometimes more likely to recall events that never happened than events that actually took place ( Brainerd & Reyna, 1998)! The original memory is not destroyed instead, people are sometimes unable to tell the difference between what actually happened and what they merely heard about or imagined ( Neuschatz, Lampinen, Toglia, Payne, & Cisneros, 2007). This reconstructive process can lead to huge errors. Bartlett proposed that people also use schemata to “reconstruct” memories ( Bartlett, 1932). Earlier, we talked about how schemata are used in storing information in long-term memory. The Reconstructive Process Forgetting also occurs because of what is called the “reconstructive” nature of remembering. For example, if people learn material while under the influence of caffeine, recall of the material is slightly improved when they are again under the influence of caffeine ( Kelemen & Creeley, 2003). Researchers have found that people who learn material in a particular physiological state tend to recall that material better if they return to the same state they were in during learning ( de-l’Etoile, 2002 Kelemen & Creeley, 2003 Riccio, Millin, & Gisquet-Verrier, 2003). Our ability to accurately recall information is also affected by internal cues, a phenomenon known as state-dependent memory. Nevertheless, contextual cues are occasionally used by police who sometimes take witnesses back to the scene of a crime in the hope that they will recall crucial details that can be used to solve the crime. Context-dependent memory effects tend to be small, so studying in the same classroom where you are scheduled to take an exam will probably not do too much to improve your grade. If those environmental cues are absent when we try to recall what we learned, the effort to remember is often unsuccessful. That information becomes useful when we later try to retrieve the corresponding information from LTM. Situational Factors Whenever we try to memorize something, we are also unintentionally picking up information about the context in which the learning is taking place.
