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.
