Mémoire (psychologie)thumb|350px|Les formes et fonctions de la mémoire en sciences. En psychologie, la mémoire est la faculté de l'esprit d'enregistrer, conserver et rappeler les expériences passées. Son investigation est réalisée par différentes disciplines : psychologie cognitive, neuropsychologie, et psychanalyse. thumb|Pyramide des cinq systèmes de mémoire. Le courant cognitiviste classique regroupe habituellement sous le terme de mémoire les processus dencodage, de stockage et de récupération des représentations mentales.
Memory consolidationMemory consolidation is a category of processes that stabilize a memory trace after its initial acquisition. A memory trace is a change in the nervous system caused by memorizing something. Consolidation is distinguished into two specific processes. The first, synaptic consolidation, which is thought to correspond to late-phase long-term potentiation, occurs on a small scale in the synaptic connections and neural circuits within the first few hours after learning.
Souvenir (mémoire)Un souvenir est quelque chose dont on se remémore, un élément de la mémoire. Paul Valéry Pour René Descartes, la description des mécanismes psychologiques permet de définir certaines de nos facultés. Ainsi le souvenir des choses matérielles est-il la conservation de certaines traces de mouvements provoqués dans notre cerveau. De même, l'imagination ne s'explique que par des mouvements corporels joints à une certaine activité de l'âme.
Emotion and memoryEmotion can have a powerful effect on humans and animals. Numerous studies have shown that the most vivid autobiographical memories tend to be of emotional events, which are likely to be recalled more often and with more clarity and detail than neutral events. The activity of emotionally enhanced memory retention can be linked to human evolution; during early development, responsive behavior to environmental events would have progressed as a process of trial and error.
Repères temporels dans la mémoire autobiographiqueLes repères temporels représentent les périodes de temps spéciaux de notre vie stockés dans la mémoire qui nous aident à organiser le stockage des autres événements. Ils jouent un rôle important dans la structuration de la mémoire autobiographique, la reconstruction et la consolidation des souvenirs stockés, l'encodage des nouveaux et la récupération des anciens souvenirs. Les repères temporels forment un système de référence personnel basé sur l'expérience et le passé personnel, différent pour chaque individu.
Explicit memoryExplicit memory (or declarative memory) is one of the two main types of long-term human memory, the other of which is implicit memory. Explicit memory is the conscious, intentional recollection of factual information, previous experiences, and concepts. This type of memory is dependent upon three processes: acquisition, consolidation, and retrieval. Explicit memory can be divided into two categories: episodic memory, which stores specific personal experiences, and semantic memory, which stores factual information.
Visual memoryVisual memory describes the relationship between perceptual processing and the encoding, storage and retrieval of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. Visual memory is a form of memory which preserves some characteristics of our senses pertaining to visual experience. We are able to place in memory visual information which resembles objects, places, animals or people in a mental image.
Faux souvenirsthumb|upright=1.5|Mémoire retrouvée (Recovered Memory), une sculpture de Nicola Hicks sur le thème de la mémoire retrouvée. Un est un phénomène psychologique qui se produit lorsqu'une personne se remémore un événement qui, en fait, n'a pas eu lieu. Les observations ou les hypothèses sur l'existence de faux souvenirs remontent aux débuts de la psychanalyse et de la psychologie clinique ; on les retrouve dans les écrits de Sigmund Freud et Pierre Janet.
Autobiographical memoryAutobiographical memory (AM) is a memory system consisting of episodes recollected from an individual's life, based on a combination of episodic (personal experiences and specific objects, people and events experienced at particular time and place) and semantic (general knowledge and facts about the world) memory. It is thus a type of explicit memory. Conway and Pleydell-Pearce (2000) proposed that autobiographical memory is constructed within a self-memory system (SMS), a conceptual model composed of an autobiographical knowledge base and the working self.
Encoding (memory)Memory has the ability to encode, store and recall information. Memories give an organism the capability to learn and adapt from previous experiences as well as build relationships. Encoding allows a perceived item of use or interest to be converted into a construct that can be stored within the brain and recalled later from long-term memory. Working memory stores information for immediate use or manipulation, which is aided through hooking onto previously archived items already present in the long-term memory of an individual.
