    Study Notes

    Memory and Working Memory

    • Memory stores all lifetime learned information, including episodes, meanings of words, and core notions about oneself.
    • Working memory holds information temporarily to support reasoning, problem-solving, and decision-making.
    • Three fundamental memory processes are encoding (acquiring information), storage (maintaining), and retrieval (accessing).
    • Memory failure can result from issues in any of these processes.
    • Memory systems are more complex than a simple dichotomy between short-term and long-term memory.
    • Short-term memory (now working memory) is likened to RAM (storing limited amount of information briefly).
    • Long-term memory is more like a hard disk (storing large amount of information permanently).
    • Working memory has a "central executive" and "slave systems" (visuospatial sketchpad and phonological loop) for temporary storage.

    One Memory or Many Memories

    • Memory involves temporary and permanent systems (e.g. sensory register, short-term memory).
    • Temporary systems include sensory registers and short-term memory (STM).
    • Sensory registers briefly hold sensory information for each sense (visual, auditory, etc.).
    • Limited capacity in STM (e.g. 5-9 items). It is quickly lost unless rehearsed.
    • Information can be transferred to long-term storage (LTM), which has virtually unlimited capacity and duration.

    Multi-store Model

    • The model proposed by Atkinson and Shiffrin (1968) describes memory as a three-stage process.
    •  Memory traces enter three storage systems—sensory register, short-term memory (STM), and long-term memory (LTM)—before being encoded permanently.

    Measuring Working Memory Capacity

    • Span procedure: measuring WM capacity by presenting increasingly longer sequences of items and observing the maximum remembered.
    • Methods to measure different components of working memory exist, for example, the Digit Span subtest.

    Permanent Systems (Long-Term Memory)

    • LTM stores information permanently, virtually unlimited in capacity and duration.
    • LTM has two broad categories: explicit and implicit.

    Explicit vs Implicit Memory

    • Explicit (declarative) memory is consciously accessed, often in verbal form.
    • Implicit (nondeclarative) memory is non-verbal and potentially unconscious.

    Episodic vs Semantic Memory

    • Episodic: memories of specific past events in a specific time and place, rich in sensory details.
    • Semantic: memories of general factual knowledge, detached from specific times or places.

    Source Monitoring

    • Ability to recall the source or origin of an event.

    Episodic Future Thinking

    • Mentally simulating future events relies on retrieving relevant past memories.

    Autobiographical Memory

    • A complex blend of memories of specific and recurring events, integrated into a narrative of self.

    Prospective Memory

    • Remembering to perform a planned action in the future, often in response to an event or at a specific time.

    Memory Errors

    • Forgetting is failing to access a memory.
    • Misremembering is retrieving a distorted memory or one that never happened.
    • Memory errors can be adaptive.

    Memory Distortions by Misinformation

    • External information can be incorporated into existing memories, even with subtle cues.

    Memory Errors Are "Adaptive"

    • Forgetting and misremembering, while seemingly problematic, can be byproducts of adaptive properties of memory.

    Forgetting

    • Lack of encoding (missed the information): Sometimes external information is never encoded in the first place.
    • Decay (memories fading over time): Memories can weaken over time if not rehearsed or recalled.
    • Lack of cues for retrieval (missing prompts): Lack of relevant reminders prevents recall.
    • Interference: Retrieving one memory can hinder retrieving another similar one.
    • Deliberate suppression (actively forgetting): Trying to avoid recalling specific memories.

    Interference

    • Proactive interference: Older memories disrupt the retrieval of newer ones.
    • Retroactive interference: Newer memories hinder the retrieval of older ones.

    Memory Reconstructive, Not Photographic

    • Memory is like reconstructing a play, using existing elements and adding personal touches, rather than playing a taped recording.
    • Memory can be significantly influenced and potentially distorted over time due to new information, inferences, or inferences based on prior memories.
    • Misremembering, including false memories, is a potential consequence of the reconstructive nature of memory.

    How Semantic Schemas Affect Memory

    • Schemas (pre-existing knowledge) influence our memory of events: Schema consistent details are more likely to be remembered and remembered over time compared to schema-inconsistent details.
    • Schema-consistent information can result in false memories, as people may believe they saw things that weren't present in the original experience.

    How Cultural Schemas Affect Memory

    • Cultural schemas can affect memory by distorting the recollection of events, as individuals tend to reshape their memories over time to fit into their known cultural expectations.

    The Deese-Roediger-McDermott (DRM) Paradigm

    • A common research method that demonstrates false memories.
    •  Involves a list of words (related by a hidden theme) and participants are often able to recall a word (the "critical lure") which was not listed but represents the hidden theme.

    Memory Distortions by Misinformation

    • People are susceptible to incorporating misleading information.

    Memory Distortions by Misinformation - Experimentation

    • Experimental studies demonstrate that even subtle cues (wording, context) influence eyewitness' memories and perceived details, even over extended periods (e.g., a week).
    •  Misinformation can create false memories, where people "remember" things that didn't actually happen (e.g., seeing broken glass that wasn't there in a car accident).

    Memory, Emotions, and Subjective Time

    • Emotional intensity affects our subjective experience of time: emotionally arousing experiences are remembered longer/stronger compared to neutral ones.
    • Emotions affect memory: unpleasant or negative memories are remembered better than neutral or pleasant memories. This is theorized to be due to the amygdala's activation during emotional events.

    The Role of Emotions

    • Emotions serve functions both within individuals (intrapersonal) and with others (interpersonal).
    • Emotions have social and cultural functions, affecting how we experience and express them.
    • Emotions are part of our motivations.
    • Motivation is a powerful internal force that initiates and directs our actions.

    Motivation: Theories

    • Instincts: Innate, biologically-driven behaviors (e.g., hunting, mating, migrating).
    • Drives: Internal tensions that motivate behavior to maintain homeostasis (e.g., hunger, thirst).
    • Needs: Psychological states that determine behavior and change situations that are not satisfying (e.g., achievement, affiliation, power).
    • Maslow's Hierarchy of Needs: A five-stage model wherein individuals have to satisfy lower level needs before progressing to higher levels, ranging from physiological needs to self-actualization.
    • McClelland's Motives: theory focused on achievement, affiliation, and power as primary motivators.

    Motivation: Cognitive Approach

    • Self-efficacy: Belief in one's ability to succeed in a specific situation. It predicts both motivation and actual performance.
    • Weiner's causal attributions: The explanations individuals form for their successes and failures.
    • Bandura's social cognitive theory: Emphasizes the importance of observations, reinforcement, and personal characteristics (like self-efficacy) in learning and behavior.

    Language

    • Language is a uniquely human, complex system of communication.
    •  Language involves a combination of phonemes, morphemes, and grammar.

    Stages of Language Acquisition

    • Newborns can recognize speech sounds, especially their own native language, and start making sounds (babbling) and single word utterances based on their experiences with their surroundings.
    •  Phrases and sentences begin to emerge as vocabularies grow.

    Language Structures

    • Phonemes: the smallest units of sound in a language.
    • Morphemes: the smallest units of meaning in a language.
    • Syntax: rules for combining words to create sentences and phrases.

    Language and Cognition

    • Language shapes our thoughts and worldview, influencing how we categorize our experiences.
    • Sapir-Whorf hypothesis: the structure of a language can affect how its speakers conceptualize the world.

    The Relationship Between Language and Cognition

    • Language enables us to communicate with others, predict experiences, and solve complex tasks.

    Measuring Intelligence

    • Intelligence is multi-faceted with different potential measurements: Verbal, Visual-Spatial, Fluid Reasoning, Working Memory and Processing Speed are measured in different tests and indices.
    • The most well-known intelligence tests include the Wechsler scales for use across the lifespan (WPPSI, WISC, WAIS).

    Theories of Intelligence

    • Unitary views: Spearman's "g factor": a general intelligence, underlying various intellectual abilities.
    • Multi-component views: Thurstone's Primary Mental Abilities: Multiple elements of intelligence.
    • Hierarchical views: Cattell's fluid and crystallized intelligence and Carroll's three-stratum model: combining aspects of unitary and multi-component models.
    • Multiple intelligences: Gardner's theory of multiple intelligences: Suggesting multiple forms of intelligence (musical, bodily-kinesthetic, interpersonal, intrapersonal).

    The Flynn Effect

    • Average IQ scores have risen steadily across generations.

    Personality Theories

    • Lay Definitions: focus on social attractiveness, behaviours.
    • Nomothetic: personality traits are assumed to be stable across time and situations with a focus on generalizing across people.
    • Idiographic: emphasis on individual characteristics and experiences, seeking to capture uniqueness in each individual.
    • Trait Theories: personality is organized into enduring characteristics—traits—that influence behaviour.
    • Psychoanalytic Theories: personality is formed by unconscious conflicts and internal motivational forces.
    • Social-cognitive Theories: personality is a continuous interaction of internal variables, behaviors, and environment.
    • Humanistic Theories: emphasizes a person's potential for growth and self-actualization.

    Personality Disorders

    • Persistent patterns of maladaptive traits and behaviours that disrupt an individual's functioning.

    Personality Inventories

    • Questionnaires that assess personality traits with specific items representing particular personality traits.
    •  Big 5 Inventory: assesses the Big Five personality dimensions: extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. 

    Projective Tests

    • Presenting ambiguous stimuli like pictures or inkblots and asking individuals to interpret them, revealing unconscious feelings, motives, and conflicts.
