    Study Notes

    Memory Across the Lifespan

    • Key questions for the course include:
      • Key factors in cognitive development
      • Applications of theory to early childhood education
      • Issues related to children as witnesses

    Early Brain Development

    • Brain development is a continuous process
    • Involves stages and differentiation

    Brain Development Across the Lifespan

    • Experience-dependent synapse formation is crucial
    • Neurogenesis in the hippocampus is vital
    • Synaptogenesis timelines vary across the lifespan; significant growth in childhood, reaching maturity in early adulthood, and maintenance/decline in later life.
    • Cognitive functions, like language and perception, are tied to brain development and areas. Specific brain areas, like the visual cortex and auditory cortex, are linked to sensory processing at different ages, while the prefrontal cortex and its connections play key roles in complex cognitive functions like planning and higher-order memory.
    • Specific developmental processes such as neurogenesis and synaptogenesis impact the development of memory and cognition throughout the lifespan; their proper functioning is essential to memory and cognitive processes across life stages.

    Early Cognitive Development

    • Caregivers play a vital role in early cognitive development
    • Factors like sensorimotor development, nutrition, cognitive stimulation, and maturational milestones are critical
    • Institutionalization can have a negative impact on cognitive development, reducing IQ scores, academic performance, attention control, and behavioral activity. This negative effect impacts various cognitive domains. Early stimulation and interaction promote healthy development and learning.
    • Early experiences significantly impact cognitive development, with quality caregiving and targeted interactions facilitating healthier outcomes. Early intervention and stimulation positively affect cognitive outcomes.

    Learning and Memory in Infants

    • Chemical sensory systems influence food preferences, and auditory sensory systems demonstrate early voice preferences in fetuses and newborns, with learning happening very early in life.
    • Sensorimotor systems involve rapid associative learning and imitation from a young age, evident as early as the perinatal period, for example infants as young as 2 months can associate kicking with an overhead mobile, showing a capacity for simple memory and learning.

    • Reverse Flynn Effect: Recent stagnation or slight decrease in intelligence scores may be influenced by factors like excessive screentime, declining values in education, and poorer health habits, impacting cognitive abilities over time.
    • Understanding the factors influencing these changes across generations is a critical component to adapting educational strategies and interventions; education and societal factors impact intellectual abilities and development.

    Brain Reserve and Neurodegeneration

    • Gray and white matter changes occur as people age.
    • Factors like excessive screen time (2-3+ hours/day, especially non-educational content), attention and concentration impairments, learning and memory deficits, emotional regulation issues, mental disorders, substance use, and physical health problems affect cognitive abilities impacting development and potentially increasing the risk for various cognitive decline and disease.
    • Factors like MCI and ADRD (Alzheimer's disease and related dementias) can be linked to these factors. Lifelong engagement in cognitive tasks and maintaining a healthy lifestyle can enhance brain reserve and potentially mitigate the risk of age-related decline and disease.
    • Cognitive stimulation, physical exercise, and maintaining social connections are crucial to maintaining cognitive function and brain reserve. Promoting brain reserve throughout life aids in potentially mitigating effects of age; this is important for preserving cognitive function and reducing age-related declines. Brain reserve is influenced by protective factors linked to lifestyle. Factors listed above are critical to maintaining optimal cognitive abilities, preventing decline, and encouraging resilience.

    Different Types of Dementias

    • Alzheimer's disease: Characterized by amyloid plaques, neurofibrillary tangles, and severe memory deficits (episodic, semantic, and procedural).
    • Vascular dementia: Caused by reduced oxygen supply to the brain, leading to memory and cognitive impairments.
    • Lewy body dementia: Alpha-synuclein deposits and unpredictable shifts in attention and concentration, often accompanied by visual hallucinations and delusions.
    • Fronto-temporal dementia: Deterioration of gray and white matter, impacting personality, behavior, and language.
