Psychology Memory Concepts

Definition of Memory

• Memory is the mental capacity to encode, store, and retrieve information.

Types of Memory

1. Sensory Memory

   • Brief, initial recording of sensory information.
   • Lasts milliseconds to seconds.
   • Examples: iconic (visual) memory, echoic (auditory) memory.

2. Short-Term Memory (STM)

   • Temporarily holds information for about 20-30 seconds.
   • Limited capacity (typically 7 ± 2 items).
   • Useful for immediate tasks and problem-solving.

3. Long-Term Memory (LTM)

   • Stores vast amounts of information for extended periods.
   • Can be explicit (declarative) or implicit (procedural).

Stages of Memory

1. Encoding

   • Process of transforming sensory input into a form usable by the brain.
   • Involves attention and can be enhanced through techniques like elaboration and mnemonics.

2. Storage

   • Maintaining information over time.
   • Involves consolidation, where memories are stabilized.
   • Can be affected by factors such as sleep and emotional states.

3. Retrieval

   • Accessing stored information.
   • Can be influenced by cues and context.
   • Types: recall (retrieving information without cues) and recognition (identifying previously learned information).

Factors Affecting Memory

• Rehearsal: Repeating information to enhance storage.
• Chunking: Grouping information into larger units for easier recall.
• Interference: New information can disrupt the recall of old information (proactive and retroactive interference).
• Context: Environmental cues can enhance retrieval.
• Emotion: Strong emotional experiences can lead to better memory retention.

Theories of Forgetting

• Decayed Memory: Information fades over time if not accessed.
• Interference Theory: Other memories disrupt retrieval.
• Motivated Forgetting: Deliberate suppression of memories.

Memory Disorders

• Amnesia: Loss of memory due to brain injury or psychological trauma.

  • Anterograde (inability to form new memories).
  • Retrograde (inability to retrieve old memories).

• Dementia: Progressive decline in cognitive function, affecting memory and other skills.

Techniques to Improve Memory

• Mnemonic Devices: Tools like acronyms or rhymes to assist memory.
• Visualization: Creating mental images to strengthen recall.
• Spaced Repetition: Reviewing information over increasing intervals to enhance retention.
• Healthy Lifestyle: Regular exercise, adequate sleep, and proper nutrition support memory functions.

Definition of Memory

• Memory encompasses encoding, storing, and retrieving information within the mind.

Types of Memory

• Sensory Memory:

  • Captures sensory information for brief moments, lasting milliseconds to seconds.
  • Includes iconic memory (visual) and echoic memory (auditory).

• Short-Term Memory (STM):

  • Retains information temporarily for approximately 20-30 seconds.
  • Has a limited capacity, typically holding 7 ± 2 items.
  • Facilitates immediate tasks and problem-solving efforts.

• Long-Term Memory (LTM):

  • Capable of storing extensive amounts of information for long durations.
  • Divided into explicit (declarative) and implicit (procedural) memory types.

Stages of Memory

• Encoding:

  • Transforms sensory input into usable information for the brain.
  • Attention and techniques like elaboration and mnemonics enhance this process.

• Storage:

  • Involves maintaining information over time, with consolidation stabilizing memories.
  • Various factors, including sleep and emotional states, can influence this stage.

• Retrieval:

  • Accessing stored information, influenced by environmental cues and context.
  • Includes two types: recall (retrieving without cues) and recognition (identifying learned information).

Factors Affecting Memory

• Rehearsal:

  • Repetition of information to improve storage of memories.

• Chunking:

  • Grouping information into manageable units for better recall.

• Interference:

  • Occurs when new information hinders the retrieval of older memories (proactive and retroactive interference).

• Context:

  • Environmental cues that can facilitate memory retrieval.

• Emotion:

  • Strong emotional experiences contribute to improved memory retention.

Theories of Forgetting

• Decayed Memory:

  • Memories fade if not accessed over time.

• Interference Theory:

  • Suggests other memories can disrupt the process of retrieval.

• Motivated Forgetting:

  • Involves the intentional suppression of certain memories.

Memory Disorders

• Amnesia:

  • Characterized by memory loss resulting from brain injury or psychological trauma.
  • Includes anterograde amnesia (difficulty forming new memories) and retrograde amnesia (difficulty retrieving old memories).

• Dementia:

  • A progressive decline in cognitive abilities impacting memory and other functions.

Techniques to Improve Memory

• Mnemonic Devices:

  • Techniques such as acronyms or rhymes that aid in memory retention.

• Visualization:

  • Forming mental images to strengthen recall capabilities.

• Spaced Repetition:

  • Reviewing information at spaced intervals to bolster retention.

• Healthy Lifestyle:

  • Regular exercise, sufficient sleep, and balanced nutrition can enhance memory function.
