Nonepisodic autobiographical memory details reflect attempts to tell a good story.

A persistent finding in the autobiographical memory (AM) literature is that older adults report more nonepisodic (or generalized/semantic) information than young adults. Since studies are usually focused on memory for episodic (or specific) autobiographical events, the reason for the age difference in nonepisodic AM remains understudied. This experiment investigated whether the higher rate of nonepisodic AM in older adults reflects (a) a difference incommunicative preferences or (b) cognitive decline, by way of either an inhibition deficit or as a means of compensating for a deficit in episodic AM. A sample of 54 young (N = 28, age range = 18-46) and older (N = 26, age range = 62-86) participants retrieved the same AM twice, under two different sets of instructions: to tell a good story for their autobiography, or to provide a detailed police witness statement. Both groups reported more general details when they were aiming to tell a good story. In addition, older adults also reported fewer specific details when the aim was to tell a good story. In a separate ranking task, young and older adults differed in their perceptions of what makes a good story; young adults ranked "detail," "grammar," and "full descriptions" more highly than older adults, whereas older ranked "linking ideas" and "explaining not just describing" more highly than young adults. The results suggest that age-related differences in nonepisodic AM might be explained by communicative preferences rather than cognitive decline.

The reminiscence bump and the self: evidence from five studies on positive and negative memories.

A plethora of studies have shown that people persistently remember public and personal events experienced during adolescence and early adulthood, particularly with a positive valence. In five studies, we investigate the reminiscence bump (RB) for positive and negative memories of public events (Studies 1 and 2), private events (Study 3), music-related events (Study 4), and cross-cultural memory differences (i.e., China and US) (Study 5). Participants retrieved either one positive or one negative memory, indicated their Age of Encoding, and provided secondary measures, i.e., memory vividness and rehearsal (Studies 1 and 3) and emotional intensity (Studies 2 and 4). About 10,000 memories were collected and positive memories appeared generally older than negative recollections, but the RB emerged for both positive and negative memories. Furthermore, the peak was earlier for positive memories of public events (<15 years old) than for negative memories (20-40 years), while no differences were found for private events or music-related experiences (15-25 years). Chinese had their RB later than US respondents. Finally, autobiographical recollections have moderate to low associations with secondary measures of phenomenological features of memory. These findings are consistent with the identity-formation theory, providing additional and important information on the development of the Self.

In my life: memory, self and The Beatles.

In a large-scale study, we asked people for their memories of The Beatles. Over four thousand respondents completed an online questionnaire. The memory could be related to a song, album, event, TV, film, or even a personal encounter. Respondents judged the age at which the event remembered had occurred and rated the memory for vividness, emotional intensity, valence and rehearsal. We found 38% of the memories were classified as "seeing The Beatles live", 25% "buying Beatles music", 20% "love of The Beatles" and 17% of the memories were "listening to Beatles songs with other people" - what we refer to as cascading memories. Among the younger respondents (aged 26 and under), 84% of the memories were cascading in nature. The memories dated to what we term the "self-defining period" in autobiographical memory (previously termed "the reminiscence bump"), with a mean age-at-encoding of 13.6 years, which is consistent with other studies of memories associated with music. We propose that these memories reflect the formation of generational identity [Mannheim, K. (1952). The problem of generations. In K. Mannheim (Ed.), Essays on the sociology knowledge (pp. 276-321).

Memory construction: a brief and selective history.

In this short article, we provide a brief introduction to the idea that memory involves constructive processes. The importance of constructive processes in memory has a rich history, one that stretches back more than 125 years. This historical context provides a backdrop for the articles appearing in this special issue of Memory, articles that outline the current thinking about the constructive nature of memory. We argue that memory construction, either implicitly or explicitly, represents the current framework in which modern memory research is embedded.

Age effects in autobiographical memory depend on the measure.

Studies examining age effects in autobiographical memory have produced inconsistent results. This study examined whether a set of typical autobiographical memory measures produced equivalent results in a single participant sample. Five memory tests (everyday memory, autobiographical memory from the past year, autobiographical memory from age 11-17, word-cued autobiographical memory, and word-list recall) were administered in a single sample of young and older adults. There was significant variance in the tests' sensitivity to age: word-cued autobiographical memory produced the largest deficit in older adults, similar in magnitude to word-list recall. In contrast, older adults performed comparatively well on the other measures. The pattern of findings was broadly consistent with the results of previous investigations, suggesting that (1) the results of the different AM tasks are reliable, and (2) variable age effects in the autobiographical memory literature are at least partly due to the use of different tasks, which cannot be considered interchangeable measures of autobiographical memory ability. The results are also consistent with recent work dissociating measures of specificity and detail in autobiographical memory, and suggest that specificity is particularly sensitive to ageing. In contrast, detail is less sensitive to ageing, but is influenced by retention interval and event type. The extent to which retention interval and event type interact with age remains unclear; further research using specially designed autobiographical memory tasks could resolve this issue.

Déjà vu and the entorhinal cortex: dissociating recollective from familiarity disruptions in a single case patient.

Past research has demonstrated a relationship between déjà vu and the entorhinal cortex in patients with wider medial temporal lobe damage. The aim of the present research was to investigate this crucial link in a patient (MR) with a selective lesion to the left lateral entorhinal cortex to provide a more direct exploration of this relationship. Two experiments investigated the experiences of déjà vécu (using the IDEA questionnaire) and déjà vu (using an adapted DRM paradigm) in MR and a set of matched controls. The results demonstrated that MR had quantitatively more and qualitatively richer recollective experiences of déjà vécu. In addition, under laboratory-based déjà vu conditions designed to elicit both false recollection (critical lures) and false familiarity (weakly-associated lures), MR only revealed greater memory impairments for the latter. The present results are therefore the first to demonstrate a direct relationship between the entorhinal cortex and the experience of both déjà vu and déjà vécu. They furthermore suggest that the entorhinal cortex is involved in both weakly-associative false memory as well as strongly-associative memory under conditions that promote familiarity-based processing.

Flashbulb memory: referring back to Brown and Kulik's definition.

Since Brown and Kulik's (1977. Flashbulb memories. Cognition, 5, 73-99. http://doi.org/10.1016/0010-0277(77)90018-X) seminal work, a central issue in memory literature is whether flashbulb memories (FBMs) hold a special status within autobiographical recalls. To address this issue, we refer back to Brown and Kulik's definition of FBM as a snapshot of the reception context of an important public news and propose a method to identify the contents of this snapshot. Although Brown and Kulik found that the majority of FBM's contents could be classified within six canonical categories (CCs), here we claim that assessing the presence of FBMs through guided CCs' questions - as done by most researchers in this field - can be misleading. We suggest, instead, to use free recall reports to identify the consistent perceptual elements of the snapshot. Across two test-retest studies, we show that the contents of FBMs assessed by free reports and the contents of CCs assessed by guided questions, do not exactly coincide. Moreover, a structural equation model supports results of previous research about the determinants of FBM and reveals that FBM facilitates the recall of more consistent explicitly requested CCs' contents. Theoretical implications concerning the qualitative contents of FBMs and the debate about their consistency are discussed.

The self-defining period in autobiographical memory: Evidence from a long-running radio show.

This study is the first to demonstrate that a self-defining period (SP) for personally relevant music emerges spontaneously in a public naturalistic setting. While previous research has demonstrated that people tend to have better memory and preference for songs from their teenage years, the theoretical relevance of these studies has been limited by their reliance on forced-choice methodology and a confinement to contemporary popular Western music. Here, we examine the record choices of famous guests (n = 80; mean age = 61.6 years) interviewed for Desert Island Discs, a long-running popular radio programme on BBC Radio 4. Half of all choices were shown to have been most important between the ages of 10 and 30 years, and the most popular reason for their relevance was the song's link to memories of a person, period, or place. We suggest that music is a defining feature of the SP, intrinsically connected to the developing self.

Mnemoscape: Supporting Older Adults' Event Memory Using Wearable Camera Photographs on an Immersive Interface.

BACKGROUND: Wearable camera photographs have been shown to be an effective memory aid in people with and without memory impairment. Most studies using wearable cameras as a memory aid have presented photographs on a computer monitor and used a written diary or no review as a comparison. In this pioneering study, we took a new and innovative approach to wearable camera photograph review that embeds the photographs within a virtual landscape. This approach may enhance these benefits by reinstating the original environmental context to increase participants' sense of re-experiencing the event. OBJECTIVE: We compare the traditional computer monitor presentation of wearable camera photographs and actively taken digital photographs with the presentation of wearable camera photographs in a new immersive interface that reinstates the spatiotemporal context. METHODS: Healthy older adults wore wearable or took digital photographs during a staged event. The next day and 2 weeks later, they viewed wearable camera photographs on a computer monitor or in context on an immersive interface, or digital photographs. RESULTS: Participants who viewed wearable camera photographs in either format recalled more details during photo viewing and subsequent free recall than participants who viewed digital photographs they had taken themselves. CONCLUSION: Wearable camera photographs are an effective support for event memory, regardless of whether they are presented in context in an experience-near format.

Cultural self-goals influence how much is remembered from early childhood events.

OBJECTIVE: Prior work examining the role of cultural self-goals on the retrieval of early memories treated the presence of self-goals; such as autonomy and relatedness, as a binary category which has led to overlooking within-group nuances. Here, based on the idea that these goals co-exist in varying degrees in individuals, we explore the relative contributions of self-goals on age-at-event and the level of detail in positive and negative early memories. METHOD: Participants (N = 119) recalled and dated two earliest positive and negative memories that they were highly confident were memories, and answered a set of questions about event-specific details. They also completed a self-construal scale. RESULTS: For positive memories, Autonomous-Related Self scores predicted both the age-at-event and the amount of detail in early memories, while. no such relationship was observed for negative memories. CONCLUSIONS: Together these findings indicate that cultural self-goals operate on the accessibility of early memories not only at the level of the boundaries of childhood amnesia but also on how much is recalled from early experiences.

Memory for staged events: Supporting older and younger adults' memory with SenseCam.

Two experiments measured the effect of retrieval support provided by a wearable camera, SenseCam, on older and younger adults' memory for a recently experienced complex staged event. In each experiment, participants completed a series of tasks in groups, and the events were recalled 2 weeks later, after viewing SenseCam images (experimental condition) or thinking about the event (control condition). When IQ and education were matched, young adults recalled more event details than older adults, demonstrating an age-related deficit for novel autobiographical material. Reviewing SenseCam images increased the number of details recalled by older and younger adults, and the effect was similar for both groups. These results suggest that memory can be supported by the use of SenseCam, but the age-related deficit is not eliminated.

Fictional First Memories.

In a large-scale survey, 6,641 respondents provided descriptions of their first memory and their age when they encoded that memory, and they completed various memory judgments and ratings. In good agreement with many other studies, where mean age at encoding of earliest memories is usually found to fall somewhere in the first half of the 3rd year of life, the mean age at encoding here was 3.2 years. The established view is that the distribution around mean age at encoding is truncated, with very few or no memories dating to the preverbal period, that is, below about 2 years of age. However, we found that 2,487 first memories (nearly 40% of the entire sample) dated to an age at encoding of 2 years and younger, with 893 dating to 1 year and younger. We discuss how such improbable, fictional first memories could have arisen and contrast them with more probable first memories, those with an age at encoding of 3 years and older.

Intentionally fabricated autobiographical memories.

Participants generated both autobiographical memories (AMs) that they believed to be true and intentionally fabricated autobiographical memories (IFAMs). Memories were constructed while a concurrent memory load (random 8-digit sequence) was held in mind or while there was no concurrent load. Amount and accuracy of recall of the concurrent memory load was reliably poorer following generation of IFAMs than following generation of AMs. There was no reliable effect of load on memory generation times; however, IFAMs always took longer to construct than AMs. Finally, replicating previous findings, fewer IFAMs had a field perspective than AMs, IFAMs were less vivid than AMs, and IFAMs contained more motion words (indicative of increased cognitive load). Taken together, these findings show a pattern of systematic differences that mark out IFAMs, and they also show that IFAMs can be identified indirectly by lowered performance on concurrent tasks that increase cognitive load.

Switching memory perspective.

The perspective in which memories were spontaneously recalled, field (original perspective) or observer (see oneself in the memory), was examined for both recent and remote memories. Recent memories were dominated by field perspective whilst remote memories were dominated by observer perspective. Further, field memories contained reliably more episodic detail than observer memories. After a 1-week interval, the same memories were recalled again but with a switched memory perspective. Switching from an observer to a field perspective did not reliably increase the amount of episodic details in a memory. Switching from field to observer perspective did, however, reliably reduce the number of episodic details. These findings suggest that memories may be represented in long-term memory with a fixed perspective, either field or observer, which can be temporarily altered sometimes changing the nature of a memory, i.e. how much detail remains accessible.

Conditioned responses to trauma reminders: How durable are they over time and does memory integration reduce them?

BACKGROUND AND OBJECTIVES: Stimuli associated with the trauma are important triggers for intrusive memories after a traumatic event. Clinical models assume that fear conditioning for neutral stimuli encountered during traumatic events is a potential cause of these intrusions, and that memory integration has the effect of reducing these associations, thereby also reducing intrusions. This study examines whether conditioned associations lead to intrusive trauma memories and how they are affected by memory integration. METHODS: Forty-eight healthy participants watched a neutral and a "traumatic" film, both containing neutral sounds, and, on the following day, were randomly allocated to memory integration of either the "traumatic" film or the neutral film. Intrusive memories were monitored for one week. Participants repeatedly completed a memory triggering task, in order to assess how durable conditioned intrusive memories are over time. RESULTS: Trauma-associated sounds elicited intrusive memories and anxiety when encountered directly after film presentation, as well as one and seven days later. Furthermore, enhanced conditionability predicted subsequent ambulatory trauma intrusions. No evidence was found for the assumption that memory integration of the "traumatic" film reduced conditioned reactions. LIMITATIONS: The presented film is a relatively mild stressor as compared to a real-life trauma. Further studies are needed to explore the role of conditioned intrusions for real-life trauma. CONCLUSIONS: This study provides evidence for the assumption that intrusive trauma memories can be explained by conditioned responses to neutral stimuli encountered during the trauma and that these effects are stable over time. Implications for PTSD and its treatment are discussed.

Supporting older and younger adults' memory for recent everyday events: A prospective sampling study using SenseCam.

This study measured the effect of a wearable camera, SenseCam, on older and younger adults' memories of recently experienced everyday events. Participants used SenseCam to prospectively sample events from a typical week, which they recalled two weeks later. Recall was cued by a self-generated title only (control condition), by the title and forward-order SenseCam images, or by the title and random-order SenseCam images. In the control condition, older and younger adults' memories were comparably episodic, but older adults recalled more semantic details. Both forward- and random-order SenseCam images were associated with increased episodic and semantic recall in both groups, and there was a small but significant effect of temporal order favouring the forward-order condition. These findings suggest that SenseCam is effective in supporting retrieval of memory for recent events, and the results of the temporal order manipulation also shed light on the mechanism of SenseCam's effect.
