What is reconsolidation in psychology?

n. the neurobiological stabilization of a reactivated memory. Research suggests that reconsolidation is necessary each time a memory is reactivated and that, prior to reconsolidation, the memory is unstable and susceptible to being changed or lost.

What are the three processes of memory?

The brain has three types of memory processes: sensory register, short-term memory, and long-term memory.

What is the competitive trace theory?

In this framework dubbed the Competitive Trace Theory (CTT), consolidation events that lead to the strengthening of memories enhance conceptual knowledge (semantic memory) at the expense of contextual details (episodic memory). As a result, remote memories are more likely to have a stronger semantic representation.

What is an example of reconsolidation?

As an example, a child learns a language while growing up. The child is then adopted into a family that speaks a different language. The child then learns to speak their family’s language. Then several years later the older child or adult is exposed to their first language again.

What is the basic idea of reconsolidation?

The hypothesis of memory reconsolidation predicts that when a memory is active (following training or reactivation) it is in a labile state, and when inactive it is stable. This implies that every time a memory is reactivated it becomes transiently labile.

What is Trace transformation theory?

Trace Transformation Theory (TTT) initially proposed that neural and psychological transformations are linked and proceed in tandem.

Who proposed multiple trace theory?

Given these and other weaknesses of the standard theory, Nadel and Moscovitch [61] generated a new model called the multiple trace theory (henceforth MTT; see Estes 1955 and Hintzman 1986 for mention of multiple traces in cognitive models of anterograde memory), which sought to account for the facts of systems-level …

What is the process of reconsolidation memory?

Reconsolidation. Memory reconsolidation is the process of previously consolidated memories being recalled and actively consolidated. It is a distinct process that serves to maintain, strengthen and modify memories that are already stored in the long-term memory.

What is memory reconsolidation theory?

What are the 3 theories of forgetting?

Abstract. There are at least three general categories of theories of memory which suggest reasons why we forget. The theories can be classified as psychological, neurochemical, and physiological. These theories, plus descriptions of aging studies that relate to them, constitute the text of the present chapter.

What are the four theories of memory?

This paper compares four current theories of expertise with respect to chess players’ memory: Chase and Simon’s chunking theory, Holding’s SEEK theory, Ericsson and Kintsch’s long-term working memory theory, and Gobet and Simon’s template theory (Chase, W.G., Simon, H.A., 1973a.

What are the 5 stages of memory?

The 5 stages of remembering

• Sensing. The very beginning of the memory-making process involves the exposure to surrounding scenes and situations.
• Encoding. With the sensory information passed to the brain, the volume and complexity is too great to process.
• Consolidation.
• Storage.
• Retrieval.

What are the 5 types of memory?

Memory Types

• Long-Term Memory. Long-term memory is our brain’s system for storing, managing, and retrieving information.
• Short-Term Memory.
• Explicit Memory.
• Implicit Memory.
• Autobiographical Memory.
• Memory & Morpheus.

Is the hippocampus a neocortical structure?

At the neural level, episodic memories are transformed from being dependent on the hippocampus to becoming represented in neocortical structures, such as the medial prefrontal cortex (mPFC), and back again, while at the psychological level, detailed, perceptually rich memories, are transformed to ones retaining only …

What does multiple trace theory propose?

Multiple trace theory is a memory consolidation model advanced as an alternative model to strength theory. It posits that each time some information is presented to a person, it is neurally encoded in a unique memory trace composed of a combination of its attributes.

What happens during reconsolidation?

What are the 4 theories of forgetting?

The five popular theories of forgetting are trace decay theory, displacement theory, retrieval theory, interference theory, and the consolidation theory of forgetting.

Is there a biophysically detailed model of neocortical local field potentials?

A biophysically detailed model of neocortical local field potentials predicts the critical role of active membrane currents. Neuron 79, 375–390. doi: 10.1016/j.neuron.2013.05.023 Reyes-Puerta, V., Kim, S., Sun, J.-J., Imbrosci, B., Kilb, W., and Luhmann, H. J. (2015a).

How columns in the neocortex enable learning the structure of the world?

A Theory of How Columns in the Neocortex Enable Learning the Structure of the World. Neocortical regions are organized into columns and layers. Connections between layers run mostly perpendicular to the surface suggesting a columnar functional organization.

How does the neocortex process sensory input?

The neocortex processes sensory input in a series of hierarchically arranged regions. As input ascends from region to region, cells respond to larger areas of the sensory array and to more complex features.

How do multi-column networks recognize objects in the neocortex?

Multi-column networks recognize objects with significantly fewer movements of the sensory receptors. Given the ubiquity of columnar and laminar connectivity patterns throughout the neocortex, we propose that columns and regions have more powerful recognition and modeling capabilities than previously assumed. The neocortex is complex.
