    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.
