Experiences of aiding autobiographical memory Using the SenseCam

Human memory is a dynamic system that makes accessible certain memories of events based on a hierarchy of information, arguably driven by personal significance. Not all events are remembered, but those that are tend to be more psychologically relevant. In contrast, lifelogging is the process of automatically recording aspects of one's life in digital form without loss of information. In this article we share our experiences in designing computer-based solutions to assist people review their visual lifelogs and address this contrast. The technical basis for our work is automatically segmenting visual lifelogs into events, allowing event similarity and event importance to be computed, ideas that are motivated by cognitive science considerations of how human memory works and can be assisted. Our work has been based on visual lifelogs gathered by dozens of people, some of them with collections spanning multiple years. In this review article we summarize a series of studies that have led to the development of a browser that is based on human memory systems and discuss the inherent tension in storing large amounts of data but making the most relevant material the most accessible

Hippocampal BDNF regulates a shift from flexible, goal-directed to habit memory system function following cocaine abstinence.

The transition from recreational drug use to addiction involves pathological learning processes that support a persistent shift from flexible, goal-directed to habit behavioral control. Here, we examined the molecular mechanisms supporting altered function in hippocampal (HPC) and dorsolateral striatum (DLS) memory systems following abstinence from repeated cocaine. After 3 weeks of cocaine abstinence (experimenter- or self-administered), we tested new behavioral learning in male rats using a dual-solution maze task, which provides an unbiased approach to assess HPC- versus DLS-dependent learning strategies. Dorsal hippocampus (dHPC) and DLS brain tissues were collected after memory testing to identify transcriptional adaptations associated with cocaine-induced shifts in behavioral learning. Our results demonstrate that following prolonged cocaine abstinence rats show a bias toward the use of an inflexible, habit memory system (DLS) in lieu of a more flexible, easily updated memory system involving the HPC. This memory system bias was associated with upregulation and downregulation of brain-derived neurotrophic factor (BDNF) gene expression and transcriptionally permissive histone acetylation (acetylated histone H3, AcH3) in the DLS and dHPC, respectively. Using viral-mediated gene transfer, we overexpressed BDNF in the dHPC during cocaine abstinence and new maze learning. This manipulation restored HPC-dependent behavioral control. These findings provide a system-level understanding of altered plasticity and behavioral learning following cocaine abstinence and inform mechanisms mediating the organization of learning and memory more broadly

Serious Games Application for Memory Training Using Egocentric Images

Mild cognitive impairment is the early stage of several neurodegenerative diseases, such as Alzheimer's. In this work, we address the use of lifelogging as a tool to obtain pictures from a patient's daily life from an egocentric point of view. We propose to use them in combination with serious games as a way to provide a non-pharmacological treatment to improve their quality of life. To do so, we introduce a novel computer vision technique that classifies rich and non rich egocentric images and uses them in serious games. We present results over a dataset composed by 10,997 images, recorded by 7 different users, achieving 79% of F1-score. Our model presents the first method used for automatic egocentric images selection applicable to serious games.Comment: 11 page

Coyote\u27s Tale on the Old Oregon Trail: Challenging Cultural Memory through Narrative at the Tamástslikt Cultural Institute

This essay examines the oppositional narratives presented in a Native American museum in order to explore the efficacy of narrative as both a strategy for resistance to hegemonic narratives of the settling of the West and a medium for sharing culture. The positioning of the museum visitor as co-participant in the museum’s narratives is also considered, with a particular focus on the relationships among narrator, story, and audience. Finally, the narrative of tribal life presented in the museum is evaluated for its potential as a vehicle for both cultural change and continuity

ESTSS at 20 years: "a phoenix gently rising from a lava flow of European trauma"

Roderick J. Ørner, who was President between 1997 and 1999, traces the phoenix-like origins of the European Society for Traumatic Stress Studies (ESTSS) from an informal business meeting called during the 1st European Conference on Traumatic Stress (ECOTS) in 1987 to its emergence into a formally constituted society. He dwells on the challenges of tendering a trauma society within a continent where trauma has been and remains endemic. ESTSS successes are noted along with a number of personal reflections on activities that give rise to concern for the present as well as its future prospects. Denial of survivors' experiences and turning away from survivors' narratives by reframing their experiences to accommodate helpers' theory-driven imperatives are viewed with alarm. Arguments are presented for making human rights, memory, and ethics core elements of a distinctive European psycho traumatology, which will secure current ESTSS viability and future integrity

Houses in a Landscape: Memory and Everyday Life in Mesoamerica

In Houses in a Landscape, Julia A. Hendon examines the connections between social identity and social memory using archaeological research on indigenous societies that existed more than one thousand years ago in what is now Honduras. While these societies left behind monumental buildings, the remains of their dead, remnants of their daily life, intricate works of art, and fine examples of craftsmanship such as pottery and stone tools, they left only a small body of written records. Despite this paucity of written information, Hendon contends that an archaeological study of memory in such societies is possible and worthwhile. It is possible because memory is not just a faculty of the individual mind operating in isolation, but a social process embedded in the materiality of human existence. Intimately bound up in the relations people develop with one another and with the world around them through what they do, where and how they do it, and with whom or what, memory leaves material traces. Hendon conducted research on three contemporaneous Native American civilizations that flourished from the seventh century through the eleventh CE: the Maya kingdom of Copan, the hilltop center of Cerro Palenque, and the dispersed settlement of the Cuyumapa valley. She analyzes domestic life in these societies, from cooking to crafting, as well as public and private ritual events including the ballgame. Combining her findings with a rich body of theory from anthropology, history, and geography, she explores how objects—the things people build, make, use, exchange, and discard—help people remember. In so doing, she demonstrates how everyday life becomes part of the social processes of remembering and forgetting, and how “memory communities” assert connections between the past and the present.https://cupola.gettysburg.edu/books/1050/thumbnail.jp
