In psychology, context-dependent memory is the improved recall of specific episodes or information when the context present at encoding and retrieval are the same. In a simpler manner, "when events are represented in memory, contextual information is stored along with memory targets; the context can therefore cue memories containing that contextual information". [1]
In order to form a memory, there needs to be a strong activation of the neurons, and then there needs to be a plasticity effect—meaning, there needs to be some kind of little change in the brain.”
This finding challenged memory theories that ignored environmental interactions. Even explicit rehearsal of object names experienced disruption. Thus, memory involves active interaction with context. While the effect was clear, it was uncertain what caused it—whether participants monitored what they carried or the spatial shift itself.

Knowing utilizes semantic memory that requires perceptually based, data-driven processing. Knowing is the result of shallow maintenance rehearsal that can be influenced by many of the same aspects as semantic memory. Remember and know responses are quite often differentiated by their functional correlates in specific areas in the brain.
In regard to memory enhancement, participants that were shown a stressful picture, often remembered them a day later, which is in accordance with the theory that negative incidents have lasting effects on our memory. [29] Acute stress can also affect a person's neural correlates which interfere with the memory formation. During a stressful time ...
The enhancing effects of emotional arousal on later memory recall tend to be maintained among older adults and the amygdala shows relatively less decline than many other brain regions. [75] However, older adults also show somewhat of a shift towards favoring positive over negative information in memory, leading to a positivity effect.
Context effects also affect memory. We are often better able to recall information in the location in which we learned it or studied it. For example, while studying for a test it is better to study in the environment that the test will be taken in (i.e. classroom) than in a location where the information was not learned and will not need to be ...
