![]() An extension of this theory, Piaget proposed that the schematic frameworks that are more frequently activated will become more strongly consolidated and thus quicker and more efficient to activate later. For Piaget, these two processes, accommodation, and assimilation, are mutually reliant on one another and are vital requirements for people to form basic conceptual networks around world knowledge and to add onto these structures by utilizing preexisting learning to understand new information, respectively.Īccording to Piaget, schematic knowledge organizes features information in such a way that more similar features are grouped so that when activated during recall the more strongly related aspects of memory will be more likely to activate together. To assimilate, Piaget defined a second cognitive process that served to integrate new information into memory by altering preexisting schematic networks to fit novel concepts, what he referred to as accommodation. Piaget defined assimilation as the process of making sense of the novel and unfamiliar information by using previously learned information. Piaget's theory proposed an alternative understanding of schema based on the two concepts: assimilation and accommodation. Jean Piaget influenced the study of reconstructive memory with his theory of schema. Bartlett also showed that schema can be tied to cultural and social norms. ![]() Schema is understood to be central to reconstruction, used to confabulate, and fill in gaps to provide a plausible narrative. Schema are fairly consistent and become strongly internalized in the individual through socialization, which in turn alters the recall of episodic memory. Frederic Bartlett was one of the first psychologists to propose Schematic theory, suggesting that the individual's understanding of the world is influenced by elaborate neural networks that organize abstract information and concepts. Schema are generally defined as mental information networks that represent some aspect of collected world knowledge. All of the supplemental processes occurring during the course of reconstruction rely on the use of schema, information networks that organize and store abstract knowledge in the brain. When there are lapses in the recall of aspects of episodic memory, the individual tends to supplement other aspects of knowledge that are unrelated to the actual episode to form a more cohesive and well-rounded reconstruction of the memory, regardless of whether or not the individual is aware of such supplemental processing. Secondly, a large number of errors that occur during memory reconstruction are caused by faults in the criterion-setting and decision making processes used to direct attention towards retrieving a specific target memory. Ultimately proper recall for a desired target memory fails due to the interference of non-target memories that are activated because of their similarity. When there is little available distinctive information for a given episode there will be more overlap across multiple episodes, leading the individual to recall only the general similarities common to these memories. ![]() First, the retrieval cues used to initiate the search for a specific episode may be too similar to other experiential memories and the retrieval process may fail if the individual is unable to form a specific description of the unique characteristics of the given memory they would like to retrieve. Many errors can occur when attempting to retrieve a specific episode. By employing reconstructive processes, individuals supplement other aspects of available personal knowledge and schema into the gaps found in episodic memory in order to provide a fuller and more coherent version, albeit one that is often distorted. This complexity leaves individuals susceptible to phenomena such as the misinformation effect across subsequent recollections. The complexity required for reconstructing some episodes is quite demanding and can result in incorrect or incomplete recall. If this binding process fails, it can result in memory errors. In this manner, the various features of the experience must be joined together to form a coherent representation of the episode. Essentially, the constructive memory process functions by encoding the patterns of perceived physical characteristics, as well as the interpretive conceptual and semantic functions that act in response to the incoming information. Rather, memory is dependent on constructive processes during encoding that may introduce errors or distortions. By using multiple interdependent cognitive processes, there is never a single location in the brain where a given complete memory trace of experience is stored. ![]() Memory rarely relies on a literal recount of past experiences. The areas most actively involved in episodic encoding and retrieval are the medial temporal lobe (hippocampus) and the prefrontal lobe.
