What are some of the differences between extinction and memory reconsolidation?

Therefore, memory retrieval may initiate two potentially dissociable but opposite processes: reconsolidation and extinction. Reconsolidation acts to stabilize, whereas extinction tends to weaken, the expression of the original memory.

Which of the following is a difference between memory consolidation and reconsolidation?

Consolidation and reconsolidation refer to transient memory stabilization processes: while consol- idation processes stabilize newly acquired memories, reconsolidation processes restabilize reactivated, i.e., retrieved, established memories.

What is memory reconsolidation and what happens during the process?

Abstract. Memory reconsolidation is the process that serves to restabilize a memory that has been destabilized through memory retrieval. This retrieval-induced plasticity has been extensively studied in the hippocampus, among other neural loci.

What is memory reconsolidation in psychology?

Memory Reconsolidation in Context. Memory reconsolidation is the brain’s innate process for fundamentally revising an existing learning and the acquired behavioral responses and/or state of mind maintained by that learning.

What is extinction memory?

Memory extinction is a process in which a conditioned response gradually diminishes over time as an animal learns to uncouple a response from a stimulus (9). With contextual fear, extinction occurs when the mouse is placed into the context without shock after training.

What is fear reconsolidation?

This process, called reconsolidation, can lead to memory updating through the integration of new information into a previously consolidated memory background. Thus reconsolidation provides the opportunity to modify an undesired fear memory by updating its emotional valence to a less aversive level.

What is true about memory consolidation?

Memory consolidation is defined as a time-dependent process by which recent learned experiences are transformed into long-term memory, presumably by structural and chemical changes in the nervous system (e.g., the strengthening of synaptic connections between neurons).

How is reconsolidation memory formed?

According to the reconsolidation view, memories are susceptible to change each time they are retrieved. The next time the memory is activated the version stored during the last retrieval, rather than the version stored after the original experience, is called up.

What is the reconsolidation theory?

The ‘reconsolidation’ hypothesis holds that when a memory is recalled, its molecular trace in the brain becomes plastic. On this view, a reactivated memory has to be ‘saved’ or consolidated all over again in order for it to be stored.

What is reconsolidation theory?

What is reconsolidation in psychology example?

Reconsolidation refers to the retrieval of memories in response to a memory trace. This is how and why we can recover memories from long ago or about topics that you haven’t thought about in a long time. As an example, a child learns a language while growing up.

What is the difference between extinction and forgetting?

In the operant conditioning paradigm, extinction refers to the process of no longer providing the reinforcement that has been maintaining a behavior. Operant extinction differs from forgetting in that the latter refers to a decrease in the strength of a behavior over time when it has not been emitted.

What is the extinction phase?

Extinction is one explanation. In psychology, extinction refers to the gradual weakening of a conditioned response that results in the behavior decreasing or disappearing. In other words, the conditioned behavior eventually stops.

What is fear return?

The “return of fear” is the reappearance of fear that has undergone partial or complete extinction; the phenomenon is illustrated by clinical and other examples. The information on return of fear in humans, drawn from a review of experimental findings and clinical reports, is summarized.

How long does the synaptic consolidation of a memory take?

Memory consolidation takes probably about 5–10 minutes and consolidation is completed after about 1 hour or so – and it has been shown that if protein synthesis is blocked in animals during the acquisition of LTM then the formation of LTM is prevented (Guyton 2008, p. 726).

What is true about memory consolidation quizlet?

Memory consolidation is the process by which memories become stable in the brain. Memory reconsolidation means memories can become vulnerable to disruption when they are recalled, thus requiring them to be consolidated again.

What is the concept of reconsolidation?

the act or process of consolidating something again or in a different way.

What are the stages of memory reconsolidation?

Memory consolidation involves converting short term memories into long term memories. The consolidation process involves three steps of encoding, storage, and retrieval.

What does extinction mean in psychology?

In psychology, extinction refers to the gradual weakening of a conditioned response that results in the behavior decreasing or disappearing. In other words, the conditioned behavior eventually stops.

What is the process of extinction in psychology?

In psychology, extinction refers to the gradual weakening of a conditioned response that results in the behavior decreasing or disappearing. In other words, the conditioned behavior eventually stops. For example, imagine that you taught your dog to shake hands. Over time, the trick became less interesting.
