{{Short description| A theory of memory recall}}
'''Reconstructive memory''' is a theory of [[Recall (memory)|memory recall]], in which the act of remembering is influenced by various other cognitive processes including [[perception]], [[imagination]], [[motivation]], [[semantic memory]] and [[beliefs]], amongst others. People view their memories as being a coherent and truthful account of [[episodic memory]] and believe that their perspective is free from an error during recall. However, the reconstructive process of memory recall is subject to distortion by other intervening cognitive functions and operations such as individual perceptions, social influences, and world knowledge, all of which can lead to errors during reconstruction.

==Reconstructive process==
Memory rarely relies on a literal recount of past experiences. By using multiple interdependent cognitive processes and functions, there is never a single ___location in the brain where a given complete [[Multiple trace theory|memory trace]] of

In this manner, the various features of the experience must be joined together to form a coherent representation of the episode.<ref name="ReferenceA">{{Cite journal|
Many errors can occur when attempting to retrieve a specific episode. 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.<ref>{{cite journal | last1 = Burgess | first1 = PW | last2 = Shallice | first2 = T | year = 1996 | title = Confabulation and the control of recollection
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. When there are lapses in the recall of aspects of

===Schema===
[[Schema (psychology)|Schema]] are generally defined as mental information networks that represent some aspect of collected world knowledge. 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.<ref name=Bartlett>{{cite web|url=http://iscte.pt/~fgvs/Bartlett,%20Experiments.pdf|title="Frederick Bartlett", Some Experiments on the Reproduction of Folk-Stories, March 30, 1920
==== Jean Piaget's theory of schema ====
[[File: Jean Piaget in Ann Arbor.png|thumb|right|Jean Piaget influenced the study of reconstructive memory with his theory of schema.]]
[[Piaget's theory#Assimilation and accommodation|Piaget's theory]] proposed an alternative understanding of schema based on the two concepts: '''assimilation''' and '''accommodation'''. Piaget defined assimilation as the process of making sense of the novel and unfamiliar information by using previously learned information.
According to Piaget, schematic knowledge organizes features information in such a way that more similar features are grouped
==== Frederic Bartlett's experiments ====
[[Frederic Bartlett]] originally tested his idea of the reconstructive nature of recall by presenting a group of participants with foreign folk tales (his most famous being "War of the Ghosts"<ref>{{cite web|url=http://cla.calpoly.edu/~dlvalenc/PSY307/LINKS/GHOSTWAR.HTM|title="War of the Ghosts", March 5, 2012|
James J. Gibson built off of the work that Bartlett originally laid down, suggesting that the degree of change found in a reproduction of an episodic memory depends on
===Confirmation bias===
During retrieval of episodic memories, people use their schematic knowledge to fill in information gaps, though they generally do so in a manner that implements aspects of their own beliefs, moral values, and personal perspective that leads the reproduced memory to be a biased interpretation of the original version. [[Confirmation bias]] results in overconfidence in personal perception and usually leads to a strengthening of beliefs, often in the face of contradictory dis-confirming evidence.<ref>Plous, S. 1993.

==Associated neural activity==
[[File:Hippocampus-mri.jpg|thumb|right|MRI indicating the hippocampus]]
Recent research using neuro-imaging technology including [[Positron emission tomography|PET]] and [[Functional magnetic resonance imaging|fMRI scanning]] has shown that there is an extensive amount of distributed brain activation during the process of episodic encoding and retrieval. Among the various regions, the two most active areas during the constructive processes are the [[medial temporal lobe]] (including the [[hippocampus]]) and the [[prefrontal cortex]].<ref name="schacter">{{cite journal | last1 = Schacter | first1 = DL | last2 = Norman | first2 = KA | last3 = Koutstaal | first3 = W | year = 1998 | title = The Cognitive Neuroscience of Constructive Memory
Studies have also consistently linked the activity of the Prefrontal Cortex, especially that which occurs in the right hemisphere, to the process of retrieval.<ref>{{cite journal | last1 = Tulving | first1 = E | last2 = Kapur | first2 = S | last3 = Markowitsch | first3 = HJ | last4 = Craik | first4 = FIM | last5 = Habib | first5 = R | display-authors = et al | year = 1994 | title = Neuroanatomical Correlates of Retrieval in Episodic Memory: Auditory Sentence Recognition
==Applications==
===Eyewitness testimony===
[[Eyewitness testimony]] is a commonly recurring topic in the discussion of '''reconstructive memory''' and its accuracy is the subject of many studies. Eyewitness testimony is any firsthand accounts given by individuals of an event they have witnessed. Eyewitness testimony is used to acquire details about the event and even to identify the perpetrators of the event.<ref name="simplypsych"/> Eyewitness testimony is used often in court and is viewed
Unfortunately, eyewitness testimony can be easily manipulated by a variety of factors such as:
* [[Anxiety]] and [[Stress (psychological)|stress]]
Line 51 ⟶ 52:
====Anxiety and stress====
Anxiety is a state of distress or uneasiness of mind caused by fear<ref>{{cite web|url=http://www.dictionary.com/browse/anxiety|title=Anxiety - Define Anxiety at Dictionary.com
However, in a study by Clifford and Scott (1978), participants were shown either a film of a violent crime or a film of a non-violent crime. The participants who viewed the stressful film had difficulty remembering details about the event compared to the participants that watched the non-violent film.<ref name="simplypsych" /> In a study by Brigham et al. (2010), subjects who experienced an electrical shock were less accurate in facial recognition tests, suggesting that some details were not well remembered under stressful situations.<ref>{{Cite journal|
Further studies on flashbulb memories seem to indicate that witnesses may recall vivid sensory content unrelated to the actual event but which enhance its perceived vividness.<ref>{{Citation|
====Application of schema====
The use of schemas has been shown to increase the accuracy of recall of schema-consistent information but this comes at the cost of decreased recall of schema-inconsistent information
====Cross-race effect====
Reconstructing the face of another race requires the use of schemas that may not be as developed and refined as those of the same race.<ref>{{cite journal | last1 = Pezdek | first1 = K. | last2 = Blandon-Gitlin | first2 = I. | last3 = Moore | first3 = C. | year = 2003 | title = Children's Face Recognition Memory: More Evidence for the Cross-Race Effect | url = http://infantlab.fiu.edu/Articles/Pedzke%20et%20al%202003.pdf | journal = Journal of Applied Psychology | volume = 88 | issue = 4 | pages = 760–763 | doi = 10.1037/0021-9010.88.4.760 | citeseerx = 10.1.1.365.6517 | pmid = 12940414 | access-date = 2012-03-20 | archive-date = 2010-06-15 | archive-url = https://web.archive.org/web/20100615001905/http://infantlab.fiu.edu/Articles/Pedzke%20et%20al%202003.pdf | url-status = dead }}</ref> The [[cross-race effect]] is the tendency that people have to distinguish among other of their race than of other races. Although the exact cause of the effect is unknown,
====Leading questions====
Often during eyewitness testimonies, the witness is interrogated about their particular view of an incident and often the interrogator will use [[leading question]]s to direct and control the type of response that is elicited by the witness.<ref>
* "What was the approximate height of the robber?" which would lead the respondent to estimate the height according to their original perceptions. They could alternatively be asked:
* "How short was the robber?" which would persuade the respondent to recall that the robber was actually shorter than they had originally perceived.
Using this method of controlled interrogation, the direction of a witness cross
===Retrieval cues===
After the information is encoded and stored in our memory, specific cues are often needed to retrieve these memories. These are known as retrieval cues<ref>{{
====Cue-dependent forgetting====
[[Cue-dependent forgetting]] (also known as retrieval failure) occurs when memories are not obtainable because the appropriate cues are absent.<ref>{{
====Priming====
Priming refers to an increased sensitivity to certain stimuli due to prior experience.<ref>{{
* Group A contained 50 participants that were asked: "About how fast were the cars going when they '''hit''' each other?”
* Group B contained 50 participants that were asked: "About how fast were the cars going when they '''smashed''' each other?"
* Group C contained 50 participants and were not asked this question because they were meant to represent a control group
A week later, all of the participants were asked whether

===Confabulation===
[[File:Schizophrenia fMRI working memory.jpg|thumb|right|FMRI showing the active areas of a schizophrenic participant's brain while performing working memory tasks]]
[[Confabulation]] is the involuntary false remembering of events and can be a characteristic of several psychological diseases such as [[Korsakoff's syndrome]], [[Alzheimer's disease]], [[schizophrenia]] and traumatic injury of certain brain structures.<ref>{{Cite journal|last=Robins|first=Sarah K.|date=2019-06-01|title=Confabulation and constructive memory
In the regular process of reconstruction, several sources are used to accrue information and add detail to
===Selective memory===
Selective memory involves actively forgetting negative
* by preventing memories from being recalled, even when appropriate cues are present
* by enhancing one's own role in previous experiences, also known as motivated [[self-enhancement]]
Many autobiographies are excellent examples of motivated self-enhancement
