Study Notes
Sensory Memory
- Sensory memory holds sensory information for a brief duration, typically less than a few seconds.
Iconic Memory
- Iconic memory refers to a fleeting visual snapshot; it lasts for only a few tenths of a second and captures visual stimuli.
Echoic Memory
- Echoic memory pertains to auditory stimuli; it allows for recall of sounds and words within 3 to 4 seconds, even if attention is diverted.
Short-Term Memory
- Short-term memory retains non-sensory information for longer than a few seconds but less than one minute, functioning as a temporary storage system.
Rehearsal
- Rehearsal is the technique of repeating information mentally to maintain it in short-term memory, enhancing retention.
Chunking
- Chunking is the method of combining smaller pieces of information into larger, more manageable clusters, facilitating easier recall in short-term memory.
Working Memory
- Working memory involves the active maintenance of information in short-term storage, enabling complex cognitive tasks.
Long-Term Memory
- Long-term memory is a more permanent form of storage, capable of holding information for extended periods, from hours to years.
Anterograde Amnesia
- Anterograde amnesia is characterized by the inability to form new memories, affecting the retention of experiences after a specific event.
Retrograde Amnesia
- Retrograde amnesia involves difficulties in retrieving past memories, impacting the recall of information acquired before a particular incident.
Long-Term Potentiation
- Long-term potentiation is the strengthening of synaptic connections following rapid, brief stimulation; it is considered a core mechanism underlying learning and memory.
Reconsolidation
- Reconsolidation is the process where retrieved memories may be altered before being stored again, indicating the dynamic nature of memory.
