    Study Notes

    Brain Lobes and Areas

    • The brain is divided into four lobes: frontal, parietal, occipital, and temporal.
    • Broca's area, located in the left frontal lobe, is responsible for speech production.
    • Wernicke's area, situated in the left temporal lobe, is crucial for language comprehension.

    Functions of Brain Lobes

    • Frontal lobe: Involved in decision-making, problem-solving, control of behaviors, emotions, and language.
    • Parietal lobe: Processes sensory information like touch, temperature, and pain.
    • Occipital lobe: Responsible for visual processing.
    • Temporal lobe: Processes auditory information and is involved in memory and emotions.

    Aphasia

    • Broca's aphasia: Difficulty producing speech, but patients generally understand language.
    • Wernicke's aphasia: Fluent speech production, but often lacking meaning and comprehension.

    Phineas Gage

    • Phineas Gage suffered a traumatic brain injury to his frontal lobe.
    • The case highlighted the role of the frontal lobe in personality, decision-making, and social behaviour.

    Neuron Structure

    • Parts of a neuron: soma (cell body), dendrites, axon, myelin sheath, and axon terminals.

    Functions of Neuron Components

    • Soma: Processes information and contains the nucleus.
    • Dendrites: Receive signals from other neurons.
    • Axon: Carries signals away from the soma.
    • Myelin sheath: Insulates the axon and speeds up signal transmission.
    • Axon terminals: Release neurotransmitters for communication with other neurons.

    Significance of P-Values

    • P-values indicate the statistical significance of results.
    • A p-value of 0.01 or less is generally considered significant.
    • A p-value above 0.05 typically indicates results are not statistically significant.

    Classical Conditioning

    • A learning process where a neutral stimulus is associated with an unconditioned stimulus to produce a conditioned response.
    • Key terms: Neutral stimulus, Unconditioned Response, Unconditioned Stimulus, Conditioned Stimulus, Conditioned Response.

    Piaget's Stages of Cognitive Development

    • Sensorimotor (0-2 years): Learning through sensory experiences.
    • Preoperational (2-7 years): Symbolic thinking, egocentrism, and imagination.
    • Concrete Operational (7-11 years): Logical thinking about concrete events.
    • Formal Operational (12+ years): Abstract and moral reasoning.

    Erikson's Stages of Psychosocial Development

    • A theory describing eight stages of development across the lifespan, each with a unique psychosocial conflict.

    DSM

    • Diagnostic and Statistical Manual of Mental Disorders, used for diagnosis of mental disorders.

    Anxiety Disorders

    • The DSM outlines various anxiety disorders (Generalized Anxiety Disorder, Panic Disorder, Social Anxiety Disorder, specific phobias).
    • Key symptoms commonly include excessive worry, avoidance, and physical symptoms.

    Depressive Disorders

    • The DSM categorizes depressive disorders (Major Depressive Disorder, Persistent Depressive Disorder, Disruptive Mood Dysregulation Disorder).
    • Key symptoms comprise depressed mood, diminished interest, and potentially suicidal thoughts.

    DSM-5 New Additions

    • Disruptive Mood Dysregulation Disorder (DMDD): temper outbursts in children
    • Premenstrual Dysphoric Disorder (PMDD): severe mood disturbances linked to the menstrual cycle

    Obsessive-Compulsive Disorder (OCD)

    • Obsessions: Recurrent unwanted thoughts
    • Compulsions: Repetitive behaviours to reduce distress from obsessions.

    Schizophrenia

    • Hallucinations: Sensory experiences without external stimuli (e.g., hearing voices).
    • Delusions: False beliefs despite evidence to the contrary.

    Dissociative Disorders

    • Dissociative Identity Disorder (DID): Presence of multiple distinct personalities.
    • Dissociative disorders typically arise from trauma or extreme stress.

    Critical and Sensitive Periods

    • Periods during development that are optimal for certain developmental skills to be learnt.

    Attachment

    • Ainsworth's Strange Situation experiment: Observed attachment styles (secure, anxious, avoidant) of babies separated from their mothers.
    • Harlow's monkey experiment: Demonstrated that comfort is more important than feeding for attachment.

    John Bowlby's Attachment Theory

    • Attachment theory suggests early relationships with caregivers establish later emotional and social development.

    Language Development

    • Genie's case: Limited language development due to lack of early exposure.

    Classical Conditioning Example

    • Jeremy: Loud noise (UCS) is associated with PlayStation (CS) causing fear (CR).
