Study Notes

The Biopsychological Approach

Behavior is influenced by a combination of biological, psychological, and social factors.
For example, depression is linked to both stress and changes in brain chemistry.

The Behavioral Approach

Behavior is a product of learning and associations.
We learn through the consequences of our actions (rewards and punishments).
Famous behaviorist B.F. Skinner believed that our environment shapes our behavior.

The Psychoanalytic Approach

Focuses on the unconscious mind and its impact on behavior.
Sigmund Freud developed this approach, suggesting that unconscious thoughts influence our daily actions.

The Humanistic Approach

Believes that people are inherently good and strive for self-actualization (reaching their full potential).
We are responsible for our own growth and can make our lives worthwhile.
Famous humanist Carl Rogers believed in the potential of every individual.

The Sociocultural Approach

Studies the influence of social, ethnic, racial, and religious groups on behavior.
People from different cultures experience different opportunities, values, and expectations.
This approach also considers how cultural differences impact counseling strategies.

Cerebral Cortex

The outermost layer of the brain, responsible for high-level mental processes (thinking).
It's divided into two hemispheres, connected by the corpus callosum.
Each hemisphere controls the opposite side of the body (left hemisphere controls right side, vice versa).

Lobes of the Brain

The brain is divided into four major lobes:

Frontal Lobe

- Controls executive functions (planning, decision-making, problem-solving, regulating emotions).
- Responsible for motor control (voluntary movements).
- Contains Broca's Area (crucial for speech production, located in the left hemisphere).
- Involved in personality, behavior, impulse control, and working memory.

Parietal Lobe

- Processes and interprets sensory information (touch, pressure, pain, temperature).
-  Contributes to spatial awareness, body awareness, mathematical reasoning, and visuospatial processing (understanding objects and space).

Occipital Lobe

- Processes visual information received from the eyes.
- Involved in recognizing shapes, colors, and motion.
- Plays a role in visual perception (depth perception, understanding visual space).

Temporal Lobe

- Processes auditory information, enabling hearing and language comprehension.
-  Contains the hippocampus (important for forming long-term memories).
-  Contains Wernicke's Area (essential for language comprehension, located in the left hemisphere).
-  Linked to emotional regulation through its connection with the limbic system.

Medulla Oblongata/Brain Stem

Controls essential autonomic functions (breathing, heart rate).
Damage can result in life-threatening conditions, potentially impacting psychological well-being.

Pons

Transmits signals between the cerebellum and cerebrum.
Plays essential roles in balance, sleep regulation, and motor control.

Thalamus

Important for communication within the brain.
Influences consciousness, sleep, and alertness.

Brain-Computer Interfaces (BCIs)

Allow direct communication between the brain and external devices (computers, robots).
Detect brain activity and translate it into signals for machines to understand.

Brain-Controlled Video Games

Emerging technology using BCIs to control video games with thoughts, bypassing physical controllers.

Other Uses of BCIs

Medical Applications: Controlling wheelchairs, prosthetic limbs, preventing and treating epilepsy.
Mental Health: Monitoring attention, stress, relaxation for conditions like ADHD and anxiety.
Military and Defense: Controlling drones, enhancing soldier performance, detecting stress and fatigue.

Neurotransmitters and Behavior

Chemicals that facilitate communication between brain cells.
Imbalances in neurotransmitters can influence behavior.

Dopamine: The Pleasure and Reward Hormone

Released during activities that feel rewarding (social media, food, shopping).
Enhances feelings of pleasure and motivates repetition of rewarding actions.

Dopamine and Exercise

Released during physical activity, contributing to feelings of happiness and satisfaction.
Naturally reduces stress, making exercise a good stress reliever.

Serotonin: The Mood Stabilizer

Carries messages between the brain and body.
Impacts mood, appetite, and sleep.

Serotonin and Mood

Known as the "feel good hormone."
Normal levels contribute to focus, emotional stability, happiness, and calmness.
Low levels are linked to depression.

Serotonin and Appetite

Helps to reduce appetite during meals.

Serotonin and Sleep

Regulates sleep quality (duration and depth).
Contributes to melatonin production (regulating sleep-wake cycles).

GABA: The Brain's Calming Agent

Inhibitory neurotransmitter that reduces neural activity.
Plays a key role in stress and anxiety reduction.

GABA and Stress/Anxiety Reduction

Calms the brain.

GABA and Relaxation/Sleep

Slows down brain activity, promoting relaxation and sleep.

GABA and Mood Stabilization

Calming effect promotes emotional stability.

GABA and Preventing Seizures

Low GABA levels can lead to excessive neural firing (seizures).
GABA medication can help prevent seizures.

Left Brain, Right Brain

Lateralization of brain function: Different brain regions specialize in specific functions.
Each hemisphere has distinct functions.
Left brain is associated with language, right brain with visuospatial functions.
Opposite sides of the brain control opposite sides of the body.

Brain Imaging Techniques

Advancements in brain imaging provide a more complete understanding of brain function.
Examples include MRI, fMRI, and PET scans.

PET Scanning

Precisely measures brain activity (blood flow, oxygen usage, sugar metabolism).
Identifies active brain regions.
Used for early diagnosis of disorders like Alzheimer's Disease.
Provides a "live" view of the brain in action.

MRI Scanning

Creates static images of the brain using magnetic fields.
Detects problems like tumors, bleeding, injuries, blood vessel diseases, and infections.
Provides more detailed images than CT scans.

fMRI Scanning

Combines features of MRI and PET scans.
Offers detailed images while also capturing live brain activity.
Detects changes in blood flow to specific brain regions (measuring brain activity).
Used to investigate relationships between behavior and brain activity in different regions.

Advantages of Brain Imaging Technology

Understanding the relationship between biological factors and behavior.
Early diagnosis and treatment of disorders like Alzheimer's and schizophrenia.
Identifying brain regions involved in specific problems (e.g., phantom limb pain).
Less invasive than exploratory surgery.

Disadvantages of Brain Imaging Technology

Lack of precision: Accuracy depends on software used.
Potential errors can occur without the researcher's knowledge, decreasing validity.
Stressful for participants (claustrophobia).

Neuroplasticity

The brain's ability to adapt and change throughout life.
Neurons can create new connections and pathways, and even grow new cells.
Allows the brain to recover from injury and learn new skills.
