Chapter Eight: Memory

Definition: Inputting information into the memory system.
Failures in Encoding: Discusses the effects of improper encoding on memory recall.
Types of Processing:
- Automatic Processing: Encoding of details such as time, space, frequency, and meaning of words (e.g., recalling when you last studied).
- Effortful Processing: Requires conscious effort to recall specifics (e.g., what exactly you studied).

Brief storage of incoming sensory information (sight, sound, taste) for a few seconds.
Acts as a filter to determine importance of stimuli; unimportant information is discarded.

Temporary storage of about seven items for approximately 20 seconds.
Methods to Transfer to Long-Term Memory:
- Rehearsal: Repeating information to aid consolidation into long-term memory.
- Storage Decay: Loss of information if not rehearsed or utilized.

Two main types:
- Explicit Memory (Declarative):
  - Episodic Memory: Personal experiences and specific events.
  - Semantic Memory: General knowledge and facts (e.g., names, dates).
- Implicit Memory: Unconscious retrieval, including procedural memories (e.g., riding a bike) and emotional conditioning.

Methods of Retrieval:
- Recall: Retrieving information without cues (e.g., fill-in-the-blank tests).
- Recognition: Identifying correct information from provided cues (e.g., multiple-choice tests).
- Relearning: Easier retrieval of previously learned information after some time.

Key Brain Areas Involved:
- Prefrontal Cortex: Higher-order processing and emotional context.
- Amygdala: Emotion processing and classical conditioning.
- Hippocampus: General memory formation, especially for significant emotional events.
- Cerebellum: Motor coordination and procedural memory.

Highly detailed, vivid memories of significant events, often linked with emotional arousal (e.g., 9/11).

Amnesia Types:
- Anterograde Amnesia: Inability to form new memories after a trauma.
- Retrograde Amnesia: Loss of memories formed prior to trauma.

Suggestibility: Memory recall can be influenced by question wording.
Example Study (Loftus, 1974): Different verbs used to describe car accidents led to varying speed estimates.

False Memory Syndrome: Recall of autobiographical memories that are not accurate.
Repression: Protective mechanism for dealing with traumatic experiences.

Types of Memory Errors:
- Transience: Accessibility decreases over time due to lack of rehearsal.
- Absent-Mindedness: Forgetting due to lapses in attention.
- Blocking: Temporary inability to access information (tip-of-the-tongue phenomenon).
- Bias: Distortion of memories influenced by current beliefs (e.g., egocentric bias, hindsight bias).
- Persistence: Inability to forget memories associated with traumatic experiences, common in PTSD.

Interference Types:
- Proactive Interference: Old information hinders recall of new information.
- Retroactive Interference: New information interferes with the recall of old information.
Memory Hacks:
- Use of mnemonic devices (initialisms, acronyms).
- Chunking: Breaking down information into manageable parts for better recall.
- Elaborative rehearsal: Linking new information with existing knowledge for enhanced understanding.

Recommendations:
- Continue to rehearse information consistently.
- Minimize distractions while studying to improve focus.
- Engage in regular physical activity and get sufficient sleep to enhance cognitive function.

Memory is complex and involves different stages and types. By understanding these processes and employing effective study strategies, students can improve their memory retention and performance.
