Study Notes

Memory and Information Processing

Memory is the process of observing, converting, storing, retrieving, and utilizing information.
Mental representations are formed when sensory inputs are encoded by neuron activity, enabling recall without original stimuli.
Representational modes can include images, sounds, and words, allowing multiple forms of processing information simultaneously.
Motor representations store information about actions, while sensory representations hold info such as sounds and images.
Visual representations provide detailed mental pictures, while olfactory memories are less reliable yet evoke strong past memories.
Verbal representation is prevalent, often constituting the primary format for thinking and problem-solving.

Standard Model of Memory

The mind is compared to a computer, categorizing memory into different stores: primary (short-term) and secondary (long-term).
Information starts in sensory registers, moves to short-term memory (STM), and can be transferred to long-term memory (LTM).
Sensory registers maintain information for about half a second post-stimulus, ensuring brief mental representations.
STM holds limited information (about seven items), accessible for 20-30 seconds before it fades or is replaced.
Rehearsal techniques (maintenance and elaborative) help in retaining information, with elaborative rehearsal being more effective for LTM storage.

Information Loss and Retrieval

Information can be lost at any stage if unimportant or disrupted by traumatic events.
Serial position effect indicates better recall for items at the beginning and end of a list.
Evolving models have shifted from strict and sequential processing to understanding memory as involving multiple simultaneous pathways.

Working Memory

Working memory refers to short-term storage and processing, necessary for problem-solving and goal achievement.
It comprises three main components: a visual memory store (visuospatial sketchpad), a verbal memory store (phonological loop), and a central executive for control and manipulation.
The episodic buffer integrates various information forms and interacts with LTM.

Varieties of Long-Term Memory

Declarative memory encompasses facts (semantic) and personal events (episodic), linked with the hippocampus.
Procedural memory includes skills and tasks learned over time without conscious effort.
Explicit memory involves conscious recall, while implicit memory refers to knowledge shown through behavior without introspection.
Prospective memory focuses on future intentions, requiring both cognitive and temporal elements.

Encoding and Organization of Memory

Encoding transforms information into memory traces for future retrieval; the quality of encoding directly influences accessibility.
Level of processing varies from shallow (structural) to deep (semantic), affecting how well information is retained.
Contextual and state-dependent memory illustrates the influence of environmental factors and emotional states on recall.
Mnemonic devices leverage vivid retrieval cues to enhance memory, while techniques like the method of loci and SQ4R provide structured ways to retain information.
Networks of association organize knowledge in memory, allowing activation spreading across related nodes, facilitating recall through interconnected information.### Memory Overview
Schemas help organize experiences, enabling efficient memory storage and retrieval.
Initial understanding of events influences how information is encoded in long-term memory (LTM).

Schemas and Encoding

Schemas guide memory encoding by shaping the interpretation of events.
Default values in schemas can fill gaps in memory, leading to misclassification and inaccuracies.
Cultural models dictate the relevance of information retained and influence memory organization.

Forgetting and Memory Availability

Forgetting is characterized by the inability to retrieve information.
The availability of information refers to whether it remains stored in memory, while accessibility involves the ease of retrieval.
Long-term memories can endure for a lifetime if consolidated through spaced learning.

Memory Errors

Memory errors arise from cognitive and emotional factors, including:
- Transience: Fading of memories.
- Absentmindedness: Inattentiveness leading to forgetfulness.
- Misattribution: Incorrectly identifying the source of a memory.
- Suggestibility: Misinformation leading to erroneous memories.
- Bias: Distorted recall influenced by personal beliefs or feelings.
- Persistence: Unwanted memories that resurface.

Flashbulb Memories

Flashbulb memories are vivid recollections of significant events but often contain inaccuracies.
Emotional arousal may enhance memory but does not guarantee accuracy.

Eyewitness Testimony

Eyewitness memory is influenced by questioning techniques, with stress potentially affecting attention to detail.

Memory Across the Lifespan

Infantile amnesia describes the loss of early childhood episodic memories, influenced by neurogenesis in early development.
As individuals age, episodic memory tends to decline, whereas semantic and procedural memories may remain stable or improve.

Theories of Forgetting

Decay theory posits that memories fade over time due to lack of use.
Interference theory describes how memories overlap and hinder retrieval (proactive and retroactive interference).
Motivated forgetting involves actively suppressing unwanted memories.

Amnesia Types

Anterograde amnesia: Inability to form new memories after brain damage.
Retrograde amnesia: Loss of memories formed before brain damage, often covering short spans.

Neurological Basis of Memory

Memory systems are neuroanatomically distinct, with the hippocampus vital for explicit memory consolidation.
Implicit memory operates independently of the hippocampus but relies on other brain regions for skills and conditioning.

Long-Term Memory Types

Declarative memory includes:
- Semantic memory: General knowledge and facts.
- Episodic memory: Personal events and experiences.
Procedural memory involves skills and procedures, expressed behaviorally, without conscious recall.

Information Encoding and Organization

Effective memory encoding requires elaboration, reflection, and meaningful processing.
Retrieval cues can enhance memory access; organizing information into networks facilitates this.
Schema theory suggests memory is reconstructive, integrating specific memories with general knowledge.

Key Memory Terminology

Anterograde amnesia: Inability to learn new information.
Chunking: Organizing information into meaningful units.
Decay theory: Memories fade due to disuse.
Explicit memory: Conscious recollection of information.
Implicit memory: Non-conscious memory expression.
Prospective memory: Upcoming tasks or events to remember.### Memory and Retrieval Concepts
Retrieval: The process of bringing information from long-term memory into short-term or working memory.
Retrieval Cues: Stimuli or thoughts that assist in retrieving information from memory.
Retroactive Interference: New information interferes with the ability to recall previously learned information.
Retrograde Amnesia: Loss of memory for events that occurred before a brain injury, affecting recall from a specific time frame.
Retrospective Memory: Involves recalling events that have already occurred.

Types of Memory

Semantic Memory: A type of long-term memory that involves general world knowledge and facts, often referred to as generic memory.
Sensory Registers: Memory systems that hold information for a very brief duration, capturing immediate sensory impressions.
Sensory Representations: Information captured and stored in the brain through one of the sensory modalities.

Memory Effects and Strategies

Serial Position Effect: The tendency for individuals to recall information presented at the beginning and end of a list better than the information in the middle.
Short-term Memory (STM): Also known as working memory, it retains information accessible to consciousness for around 20-30 seconds.
Spacing: The practice of distributing learning sessions over time, enhancing retention.
Spacing Effect: Improved long-term retention of information when rehearsal sessions are spread out across longer time intervals.
Spreading Activation Theory: A concept suggesting that presenting a stimulus activates related nodes in memory, facilitating recall.

Memory Techniques and Phenomena

SQ4R Method: A mnemonic device for studying textbooks that includes steps: survey, question, read, recite, review, and write.
Synapses: Locations where neurons transmit information to each other, essential for memory formation and recall.
Tip-of-the-Tongue Phenomenon: The frustrating experience where a person knows they have information memorized but cannot retrieve it at that moment.
Verbal Representations: Information encoded and stored in the brain as words, crucial for language-based memory.
Visuospatial Sketchpad: A component of working memory that temporarily holds and manipulates visual information.
Working Memory: A conscious workspace for operations involving retrieving and manipulating information, heavily reliant on maintenance rehearsal.
