Study Notes

Atkinson-Shiffrin Model of Memory

  • Sensory memory is the initial stage of memory, where information is briefly held before being processed further.
  • Attention is necessary for information to be transferred from sensory memory to short-term memory.
  • Short-term memory (STM) is where information is actively processed and manipulated.
  • Rehearsal is a conscious process that involves repeating information in STM to increase the chances of it being encoded into long-term memory.
  • Information in STM can be lost due to displacement (being pushed out by new information) or decay (fading over time).
  • Long-term memory (LTM) stores information that has been encoded and is available for retrieval.
  • Memories in LTM can be lost over time.

Explicit Memory

  • Explicit memory, also known as declarative memory, is a type of long-term memory that can be consciously retrieved.
  • Explicit memories are consciously recalled and brought into awareness.
  • Explicit memories are also known as declarative memories because they can be declared or stated to someone else.
  • Semantic memory is a type of explicit memory that consists of general knowledge and facts.
  • Episodic memory is a type of explicit memory that consists of personal experiences or events.

Brain Structures Involved in Memory

  • The hippocampus is a brain structure primarily involved in encoding explicit memories.
  • The amygdala is involved in processing emotional memories.
  • The neocortex is responsible for storing long-term memories.
  • The basal ganglia is involved in procedural learning and memory.
  • The cerebellum is involved in motor skill memory.

Classical Conditioning

  • Classical conditioning is a type of learning where an involuntary response is associated with a previously neutral stimulus.
  • A conditioned fear response can be triggered by the repeated association of a neutral stimulus with a feared stimulus.
  • Classically conditioned memories are involuntary and can be reflexive.

Distinguishing Between Declarative and Procedural Memories

  • Declarative memories often involve "knowing that" information, such as facts and events.
  • Procedural memories often involve "knowing how" to do something, such as skills and habits.
