Study Notes
Nature of Memory
- The term "memory" derives from Latin words ‘memoria’ (mindful) and ‘memor’ (remembering).
- Memory enables the maintenance of information over time and the use of past experiences in present situations.
- It provides continuity for consciousness and assists in dealing with current situations through essential skills.
- Enhances social and emotional experiences via effective planning and performance.
Memory Processes
-
Encoding (Registration):
- Transforms sensory information into a memory-compatible format.
- Involves receiving, processing, and combining information, such as turning song lyrics into a storable format.
-
Storage (Retention):
- Converts information into permanent records using methods like maintenance rehearsal (repetition) and elaborative rehearsal (understanding).
- For example, lyrics stored through repetition or meaningful associations.
-
Retrieval (Recall or Recognition):
- Accesses and brings stored information into consciousness when required, such as recalling and singing a song.
Models of Memory
-
Atkinson and Shiffrin Model (Information Processing Model):
- Analyses human memory like a computer system, encompassing three stages: Sensory Memory, Short-term Memory, and Long-term Memory.
-
Sensory Memory:
- Characterized by large capacity and very short duration (less than a second).
-
Short-term Memory (STM):
- Holds limited information for under 30 seconds; requires rehearsal for transfer to long-term memory.
-
Long-term Memory (LTM):
- Has a vast capacity for permanent information storage through elaborative rehearsal.
Types of Memory
-
Implicit Memory (Unconscious/Automatic):
- Engages in tasks without conscious effort, such as procedural memory for motor skills (e.g., riding a bicycle).
-
Explicit Memory (Declarative):
-
Requires conscious recall of experiences and information.
-
Episodic Memory: Stores personal experiences and events (e.g., remembering a birthday).
-
Semantic Memory: Contains general knowledge (e.g., facts and concepts).
-
Forgetting
-
Hermann Ebbinghaus:
- Pioneered the systematic study of forgetting, creating the forgetting curve which shows rapid memory loss within the first hour of learning, particularly within the first nine hours.
-
Causes of Forgetting:
-
Trace Decay Theory: Suggests that memory traces fade over time if not frequently used.
-
Interference Theory:
-
Proactive Interference: Old information disrupts the recall of new information.
-
Retroactive Interference: New information hinders the recall of old information.
-
-
Techniques for Enhancing Memory
- Keyword Method: Links new information with similar-sounding words from a known language.
- Method of Loci: Visualizes items to remember as objects within a familiar physical space.
- Mnemonics using Organization: Structures material to improve retrieval ease.
- Chunking: Groups smaller units into larger, manageable chunks.
- Minimizing Interference: Advises against learning similar subjects back-to-back and encourages breaks.
- Use of Retrieval Cues: Connects elements of study material to specific cues for easier recall.
- PQRST Method: Involves Previewing, Questioning, Reading, Self-recitation, and Testing to enhance understanding and retention.
