long-term potentiation- studies of neurons indicate that they can strengthen connections between each other through repeated firings, this might be related to the connections we make in our long-term memory.Damage can cause anterograde amnesia (can’t encode any new memories) the hippocampus is important in encoding new memories.How memories are physically stored in the brain. Proactive interference – older information learned previously interferes with the recall of information learned more recently. Retroactive interference – learning new information interferes with the recall of older information.Another factor is interference, two types Relearning effect indicates that it isn’t entirely gone. One cause is decay, because we do not use a memory or connection to a memory for a long time. Constructive Memory – false memories, leading questions can easily influence us.Mood-congruent memory- ability to recall a memory is increased when current mood matches mood when stored.Recency effect - ability to recall the items at the end of a list.Primacy effect – more likely to recall items presented at the beginning of a list.There are several factors that influence why we can retrieve some memories and why we forget others. two different kinds: recognition and recall.This theory explains why we remember stories better than a simple recitation of events and why, in general, we remember questions better than statements. According to the levels of processing theory, we remember things we spend more cognitive time and energy processing. They are deeply (or elaboratively) processed or shallowly (or maintenance) processed. Memories are neither short- nor long-term. This theory explains why we remember what we do by examining how deeply the memory was processed or thought about. Memories can also be implicit or explicitĮxplicit – also called declarative – conscious memories of facts or events Implicit – also called nondeclarative- unintentional memories that we might not even realize we have Rehearsal or simple repetition can hold information in short-term memoryĮpisodic memory – memories of specific events stored in a sequential series of events Semantic memory – general knowledge of the world stored as facts, meanings, or categories rather than sequentially Procedural Memory – memories of skills and how to perform them, These are sequential but might be very complicated to describe in words.Mnemonic devices- memory aids, really examples of chunking.Capacity can be expanded through chunking.Events are encoded as visual codes, acoustic codes, or semantic codes.capacity is limited on average to around seven items (7+/-).temporary, they usually fade in 10 to 30 seconds.Selective attention determines which sensory messages get encoded.Most of the information in sensory memory is not encoded.Other experiments indicate echoic memory – split-second memory for sounds.George Sperling did experiments, showed iconic memory – a split-second perfect photograph of a scene.the information your senses are processing right now is held in sensory memory less than a second.Three Box model proposes the three stages that information passes through before it is stored: Two of the most important models: the three-box/information processing model and the levels of processing model. Several different models or explanations of how memory works have emerged from memory research. Memory is any indication that learning has persisted over time
