Study Notes

The Human Brain

The brain is the central organ controlling our thoughts and actions.
It is composed of millions of cells called neurons.
Neurons communicate through connections called synapses.
The outer layer of the brain, called the cerebral cortex, controls movement, language, attention, and thought.
The central nervous system, comprised of the brain and spinal cord, has a symmetrical structure.
The brain is divided into two hemispheres (right and left) and four lobes.
Each lobe has specific functions:
- Frontal lobe: Controls movement and personality.
- Parietal lobe: Processes sensations and helps us understand our position in space.
- Occipital lobe: Deals with vision
- Temporal lobe: Connected to hearing, memory, emotions, and language.
Language centers are located in the temporal and frontal areas of the left hemisphere.

Brain Plasticity

The brain's ability to change and adapt in response to experiences and external stimuli is called plasticity.
The cerebral cortex is highly adaptable, particularly in early years of life, but this ability continues later.
These periods are known as "critical periods" where the brain is very sensitive to stimuli and important for learning and growth.
The brain adapts and selects the most useful circuits for survival and development.
Lack of stimulation during critical periods can cause damage difficult to recover from.
Studies by psychologist René Spitz showed the effects of lack of care in infants.
Stimuli activate genes that remain otherwise inactive.
Although less pronounced than in children, the adult brain retains the ability to adapt and change.
Individuals learning Braille experience changes in the part of the brain associated with touch.
Even after injuries or amputations, the brain can reorganize to adapt to new situations.
Keeping the brain active helps maintain its abilities over time.

Perception

Perception is how the brain gathers information from the external world through senses and past experiences.
Perception isn't always objective; it's influenced by experiences, emotions, and the surrounding environment.
There's a difference between physical reality and what we perceive due to unconscious brain processes.
Perception involves the senses, intelligence, and the entire personality.
Different schools of psychology have studied perception in various ways leading to different results.
Psychologists have researched distinguishing colors.
German scientist Hermann von Helmholtz proposed that we have receptors for red, blue, and green colors.
Helmholtz believed the brain doesn't just receive sensations but actively organizes data based on past experiences.
The brain creates a complete image of an object using unconscious processes to combine simple information.

Gestalt Theory

Perception isn't just the sum of small details but involves the organization of a set (a "form") as a whole.
We distinguish a figure from its background when perceiving.
The principle of proximity suggests we tend to perceive elements close to each other as a group.
Similar elements are more easily recognized, according to the principle of similarity.
The principle of closure states that we automatically complete incomplete shapes and images.
The principle of continuity suggests we see lines or shapes as continuous rather than separate.
The principle of good form or pregnance states that we perceive symmetrical, regular, and simple figures as more stable and pleasant.
Past experiences influence our perception – for example, we recognize the letter E due to our knowledge of the alphabet.

Functionalist Perspective

This perspective focuses on how perception is influenced by experiences and needs.
Psychologist Jerome Bruner studied variables influencing perception.
Emotions affect how we recognize objects and the time it takes to do so.
If a stimulus is perceived as painful, the brain might avoid recognizing it for protection.
Our needs influence perception – if we need something, we'll be more sensitive to relevant stimuli.
The "New Look" theory claims past experiences and emotional states actively influence how we perceive things.
This theory suggests that perception is not a passive process but an active and adaptive one.

Attention

This is our ability to focus on relevant information and ignore irrelevant information.
Attention acts as a filter selecting useful information and discarding unnecessary information.
Broadbent's theory suggests that the filter is based on a person's goals, tasks, and expectations.
Selective attention focuses on one thing at a time, filtering out other information.
Divided attention refers to the ability to perform multiple tasks at once.
Research by Hirst and Kalmar showed that two different tasks (like grammar and math) result in fewer errors than two similar tasks.
The primary task receives more attention and resources, while the secondary task receives less (example – driving is primary, listening to the radio is secondary).
Tim Shallce's model proposes that attention isn't just a filter but a system that controls cognitive operations when they conflict.
Competitive selection automatically chooses the most important task according to the moment.

Consciousness

In the late 19th century, scientists studied consciousness by asking people to "look inside themselves" and describe feelings and thoughts (introspection).
Behaviorists criticized this method, believing it wasn't scientific because it didn't yield objective and verifiable data.
Patients with split-brain (where the two hemispheres were surgically separated to treat epilepsy) showed that consciousness is the result of integration between operations of the two hemispheres.
Consciousness has been studied as a continuum ranging from coma to wakefulness, with more attentive wakefulness marked by awareness of one's actions.
The prefrontal lobes are essential for controlling mental operations and fully develop in children only after four to five years old.
There are conscious cognitive processes (conscious) and others occurring without our awareness (cognitive unconscious).
The cognitive unconscious includes automatic processes like driving without thinking.

Freud and Consciousness

Freud defined consciousness as the part of the mind receiving information from the senses and perceiving emotions of pleasure or displeasure.
Consciousness is constantly in conflict with the unconscious, which hides painful emotions and memories.
Hidden memories in the unconscious aren't erased and can resurface through dreams or events.
The preconscious is an area of the mind containing non-threatening memories readily recalled to consciousness.
The metaphor of an iceberg represents consciousness as the visible part, while the majority of memories and emotions lie hidden beneath the surface in the unconscious.

Memory

Memory is like an archive storing and organizing information and memories called "traces."
The oldest model, the associative model, suggests that we remember better if we can associate traces through contiguity, similarity, or contrast.
Hermann Ebbinghaus studied memory as a pure ability, using lists of nonsense syllables to prevent experiences or emotions from influencing memories.
Ebbinghaus memorized series of random syllables (e.g., ZUC, DAX) to measure his ability to remember them.
He discovered that repetition improved memory and decreased the time needed to learn a list.
He suggested that similar elements (like sounds or letters) helped with better recall.
Subjects had to recall a series of syllables or numbers in the same order they were presented (serial presentation).
The phenomenon of "savings" indicates that repeating a previously learned task takes less time than learning it from scratch.

HIP (Human Information Processing) Model

The model suggests memory works like a computer, receiving, processing, and storing information.
The sensory register (SR) receives information from the senses and stores it for a few tenths of a second.
The short-term memory (STM) receives information from the SR and stores it for a few seconds; it has a limited capacity.
Through a process of encoding, such as rehearsal, information from the STM is transferred to the long-term memory (LTM), which can store memories for a long time, even forever.
Once stored in the LTM, information can be retrieved when needed, making it available again.
The model helps us understand how memory works, with three main systems communicating with each other.

Memory System Breakdown

Sensory Register (SR): Stores information from the senses for a brief period.
Short-term Memory (STM) or Working Memory: Acts like a temporary notepad, storing information for a few seconds.
Encoding: The process of transforming information into something the memory can store.
Consolidation: When a memory becomes stable and moves from STM to LTM.
Storage: How memories are preserved in the LTM.
Retrieval: Recalling stored information.
Long-term Memory (LTM): Stores memories for extended periods, even a lifetime.

Types of Memory

Episodic Memory: Stores specific events and moments, like a lunch or a meeting.
Semantic Memory: Stores general knowledge like word meanings or world knowledge.
Declarative Memory: Knowledge we can consciously express (facts or definitions).
Procedural Memory: Memory for unconscious actions like riding a bicycle or swimming.

Neuroscience

Neuroscience explores the interplay between the brain (biology) and mind (psychology), investigating the interaction between humans and their environment.

Human Adaptation

Anthropologists Alesani and Argelato define humans as beings who adapt to the world through thought and symbolism, not just instinct.
Humans adapt by developing cognitive abilities and using tools, techniques, and language.
The human brain continues to grow for many years after birth, enhancing learning and adaptation abilities.
Psychology explores three fundamental aspects:
- Human Technical Capacity: The ability to transform the environment through technology.
- Impact of Technology: How inventions like writing and media affect the development of cognitive abilities.
- Risk of Technological Dominance: The risk that technology might dominate and transform nature.
Psychology works with biology and cybernetics to understand the balance between nature and technology.
Evolutionary theory views evolution as a continuous and non-linear process, emphasizing the continuity between species and the development of the human mind based on environmental stimuli.

Pedagogy and Human Adaptation

Pedagogy must create educational paths that encourage interaction between genetic inheritance and environmental stimuli.

Harnessing Differences

Recognizing that each brain is unique and has its own learning capacity is essential.
Intervention at the right time is necessary to support development.
Education should optimize natural learning abilities.
Pedagogy must understand how the brain processes information and address issues related to excessive media exposure.
There needs to be a balance between technology use and education.
Pedagogy has a duty to balance technology with nature and maintain harmony between the two.

The Mind-Computer Analogy

In the 50s, people started comparing brain function to computer processes to better understand learning and language.
The brain is a complex system, developed through millions of years of evolution, and unique to each individual, shaped by environment and personal experiences.
Neuroscience investigates the brain's physical structure and function, while psychology focuses on behavior and mental processes.
Cognitive psychology utilizes findings in cybernetics and artificial intelligence to study the mind.
Neuroscience explores various aspects of the nervous system, from biochemistry to neural connections, and connects to the philosophy of the mind.

Cognitive Neuroscience

It studies the brain's function and mental processes, exploring how neural circuits affect perception, memory, and language.
Neurotransmitters are chemical substances that allow neurons to communicate through synapses.
Simple neural structures are studied in simpler organisms to understand how our brains work.
Neuroscience investigates the biological mechanisms underlying learning and brain development, starting from the embryo.
Researchers investigate how neurons organize themselves, allowing us to perceive, remember, speak, and think.
Research methods include anatomico-clinical studies, functional activations, and animal experiments to explore the brain.
Neuroscience and psychology have overcome their division in recent decades, engaging in dialogue.

The Complexity of Mind

Science recognizes that the mind is part of a complex system, not just the sum of the brain's physical parts.
Computer simulations allow scientists to study complex systems like the brain differently from traditional experiments.
Researchers strive to understand the brain through both its physical components and cultural influences.
The experiences we have select synaptic connections in the brain, changing how we think and learn.

Mirror Neurons

These special neurons activate when we perform an action and when we see someone else doing the same action.
In the 90s, during a lab experiment, researcher Giacomo Rizzolatti and his team discovered mirror neurons. The monkey showed activation of neurons even just watching a researcher take food.
These neurons changed our understanding of learning through imitation, helping explain phenomena like imitation and understanding others' intentions.
Imitation is crucial for learning, and mirror neurons help us do so.
These studies are important for understanding conditions like Asperger syndrome and developing new therapies based on imitation.

Neuroscience and Education

Discoveries about the brain should be used to improve education, helping each individual develop their abilities to the fullest.
Children need stimulating environments from birth to develop their full mental potential. Caring and information-rich environments help children grow better.

Critical Periods in Education

Provide educational support during critical periods when cognitive abilities emerge.

Individualized Education

Recognize and celebrate each child's unique abilities and talents.
Customize education to cater to the specific needs and strengths of each individual.

High-Quality Learning Environment

Create a well-structured educational environment with adequate time, space, and resources.
Foster positive and nurturing relationships to support learning effectively.

Eco-Friendly Approach

Emphasize the importance of environmental awareness and responsibility.
Encourage children to understand their connection to nature and the environment.
Promote sustainable values and minimize anthropocentric viewpoints.
