The Seven Sins of Memory. Insights From Psychology and Cognitive Neuroscience. Daniel L. Schacter. Harvard University. Though often reliable, human. It is suggested that memory's misdeeds can be classified into 7 basic "sins": transience, absentmindedness, blocking, misattribution, suggestibility, bias, and persistence. The first three sins involve different types of forgetting, the next three refer to different types of. The Seven Sins of Memory. Transience: decreasing accessibility of memory over time. Absentmindedness: lapses of attention; forgetting to do things. Blocking.

Prospective theory- how and why different types of absent-minded forgetting occur. Chapter 3: Blocking. Failure to retrieve or access deeply encoded information — a temporal as opposed to permanent in transience inability to remember. Names of people, specific places…? Blocking also when remembering personal experiences patients temporarily lose access to large sectors of their personal pasts, and new neuroimaging studies that are providing initial glimpses into what goes on in the brain during this sort of blocking.

Chapter 4- Misattribution Failure of source-memory: Being able to remember the content but forgetting the actual source of the information and attributing it to some other source.

This can take various forms, even to the point where one thinks that real events were only imagined or things that were only imagined are thought to have happened. In some experiments, subjects show just as much confidence in their false recall as in their correctly recalled items. False memories- Is there any way to tell the differences between true and false memories?

Scan subjects while they experience true and false memories, and the results provide some insights into why false memories can be so subjectively compelling. Brain-damaged patients who are especially prone to misattributions and false memories. Our memories are sometimes permeable to outside influences: leading questions or feedback from other people can result in suggested false memories of events that never happened.

Kind of misattribution. In a recent PET TOT blocks appear to be partly attributable to study, Okuda et al. For example, in a diary study, words during scanning. In a condition that required pro- Reason and Lucas found that over half of naturally spective memory, participants were also required to retain occurring TOT states were characterized by the presence of a planned action to tap when prespecified words were what they termed "ugly sisters," referring to Cinderella's presented while carrying out other activities.

Prospective undesirable but dominating older sisters. Ugly sisters are remembering was associated with activation in a number of incorrect items that are related to the sought-after target and brain regions, most notably the surface of the right frontal that recur intrusively during the retrieval attempt. Consis- lobe dorsolateral and ventrolateral regions , the front of tent with this observation, when Jones and Langford the left frontal lobe frontal pole , and inner parts of the induced TOT states by giving definitions of low frequency frontal lobe near the midline.

The incidence of TOT states increases with aging performed well on the exact task that produced prefrontal A. This apparent link between remains unclear as to whether older adults are more sus- prospective memory and frontal lobe function makes sense ceptible to interference from "ugly sisters" than are in view of the role that frontal regions play in allowing younger adults cf.

Failure to activate in TOT states may be particularly pronounced when people appropriate frontal regions, either at the time of planning a attempt to retrieve names Maylor, However, it is unclear whether these prob- showed increased activation during naming of tools. Al- "ugly sisters" in the TOT state resemble a curious phenom- though no neuroimaging studies of TOT states have yet enon known as the "part-set cueing" effect, which has been been reported and may be difficult to carry out because of documented in laboratory studies of episodic memory in the relative infrequency of the TOT phenomenon , such which participants encode and retrieve lists of words.

In studies could provide novel insights into the neural corre- part-set cueing, provision of some retrieval cues that are lates of retrieval blocking. Perhaps the most relevant data associated with decreased memory for related but nonre- have been reported by Nyberg et al.

I find it useful Cognitive neuroscience has so far provided some rel- to distinguish among three closely related forms of evant observations concerning retrieval blocks in semantic misattribution. Within the domain of semantic from a past experience but misattribute the fact to an memory, a variety of studies have examined anomic pa- incorrect source.

For instance, individuals sometimes recall tients who have difficulties with retrieval of common encountering a bit of trivia in the newspaper that, in fact, names of objects or with retrieval of proper names. Similarly, people may assert that they common names, and still others exhibit a selective deficit in saw a face in one context when they encountered it in retrieving one type of proper name e.

Semenza et al. Source confusions of this kind can be particularly temporal pole. In a evidence, a PET study by Damasio, Grabowski, Tranel, recent study, for example, Schacter, Koutstaal, Johnson, Hichwa, and Damasio revealed activation of the left Gross, and Angell found that older adults often temporal pole during proper name production.

They revived and mod- the basis of the victim's detailed recollection of the rapist ified a paradigm that was originally devised by Deese Thomson, Fortunately for Thomson, he had an Deese had reported that when people studied lists airtight alibi: He was giving a live television interview of semantically associated words and later tried to recall ironically, concerning memory distortion at the moment them, they frequently intruded or falsely recalled a strongly that the rape occurred.

The victim had been watching that associated word that had not been previously presented.

In their paradigm, younger and some evidence of medial temporal lobe activation during older adults studied detailed colored pictures from various both true and false recognition. Differences in brain activ- categories. When given a recognition test after a three-day ity during true and false recognition were relatively small delay, older adults showed considerably higher levels of and appeared to depend on specific characteristics of rec- false recognition to nonpresented pictures from studied ognition testing procedures for a discussion, see Schacter, categories than did younger adults.

These obser- gions may be involved in strategic monitoring processes vations contrast with other studies in which older adults that are invoked as participants struggle to determine exhibit high levels of picture recognition accuracy that do whether a related lure word was actually presented earlier not differ substantially from that of younger adults e.

Blocking is a primary cause of Tip of the tongue phenomenon a temporary inaccessibility of stored information. Misattribution [ edit ] Misattribution entails correct recollection of information with incorrect recollection of the source of that information. For example, a person who witnesses a murder after watching a television program may incorrectly blame the murder on someone he or she saw on the television program.

This error has profound consequences in legal systems because of its unacknowledged prevalence and the confidence which is often placed in the person's ability to impart correctly information critical to suspect identification. One example Schacter gives [4] of eyewitness misattribution occurred in connection with the Oklahoma City bombing in Two days before, the bomber rented a van, but an employee there reported seeing two men renting it together.

One description fit the actual bomber, but the other description was soon determined to be of one of a pair of men who also rented a van the next day, and were unconnected with bombing.

Schacter also describes how to create misattribution errors using the DRM procedure. Subjects are read a list of words like sharp, pin, sewing, and so on, but not the word needle.

It is the acceptance of a false suggestion made by others. Memories of the past are often influenced by the manner in which they are recalled, and when subtle emphasis is placed on certain aspects which might seem likely to a specific type of memory, those emphasized aspects are sometimes incorporated into the recollection, whether or not they occurred.

For example, a person sees a crime being committed by a redheaded man. Subsequently, after reading in the newspaper that the crime was committed by a brown-haired man, the witness "remembers" a brown-haired man instead of a redheaded man.

Loftus and Palmer's work into leading questions is an example of such suggestibility. Bias[ edit ] The sin of bias is similar to the sin of suggestibility in that one's current feelings and worldview distort remembrance of past events.

This can pertain to specific incidences and the general conception one has of a certain period in one's life.Such biases can lead to a dangerous downward spiral. A related type of misattribution has been dubbed the having encountered a word on the list a "remember" "false fame effect" by Jacoby and colleagues e. In Jacoby et al. Although patients have shown that damage to the medial temporal the basic characteristics of the forgetting curve described lobes, including the hippocampus and related structures, by Ebbinghaus have been observed in numerous situations, produces profound long-term forgetting.
