Study Notes

Psychological Approaches

Curious Skepticism: Encourages questioning and critical thinking in psychology.
Structuralism: Focuses on breaking down mental processes into their fundamental components.
Functionalism: Emphasizes the purpose and function of mental processes in adapting to the environment.
Behaviorism: Studies observable behaviors and their relationship to stimuli, disregarding internal mental states.
Cognitive Neuroscience: Examines brain functions and their impact on cognition and behavior.
Cognitive Psychology: Investigates mental processes such as perception, memory, and problem-solving.
Evolutionary Psychology: Explores how evolutionary principles shape cognitive processes and behaviors.
Behavior Genetics: Studies the influence of genetics and heredity on behavior and mental processes.

Nature vs. Nurture

Nature: Refers to biological factors influencing behavior.
Nurture: Involves environmental influences and experiences.
Natural Selection: Process by which traits that enhance survival and reproduction become more common in a population.

Areas of Psychology

Cross-Cultural Psychology: Examines how cultural factors influence human behavior.
Gender Psychology: Investigates the impact of gender on psychological processes.
Positive Psychology: Focuses on factors that contribute to human happiness and flourishing.

Types of Psychologists

Clinical Psychologists: Assess and treat mental disorders, often working in therapy.
Counseling Psychologists: Help individuals address everyday stress, focusing on well-being and development.

Methodologies in Psychology

Descriptive Method: Observes and describes behavior without manipulating variables.
Correlation Method: Analyzes relationships between variables without inferring causation; correlation does not equal causation.
Experimental Method: Involves manipulating variables to determine cause-and-effect relationships.
Case Studies: In-depth investigations of individual cases.
Naturalistic Observations: Observing subjects in their natural environment.

Research Processes

Theory: A well-substantiated explanation of a phenomenon.
Hypothesis: A testable prediction derived from a theory.
Replication: Repeating studies to confirm findings.
Positive Correlation: Indicates that as one variable increases, the other also increases.
Negative Correlation: Indicates that as one variable increases, the other decreases.
Correlation Coefficient: A statistical measure of the strength and direction of the relationship between two variables.

Experimental Procedures

Blind Procedure: Participants are unaware of their experimental condition.
Double-Blind Procedure: Both participants and researchers are unaware of conditions to prevent bias.
Placebo Effect: Improvement in condition resulting from belief in treatment rather than actual treatment.

Neuroscience Basics

Neural Plasticity: The brain's ability to reorganize and adapt over time.
Neural Communication: Involves the transmission of signals between neurons through synapses.

Structure of Neurons

Dendrites: Receive signals from other neurons.
Axon: Transmits impulses away from the neuron.
Terminal Branches of Axon: Release neurotransmitters to communicate with other neurons.
Myelin Sheath: Insulates axons to speed up signal transmission.
Neural Impulse: The electrical charge that travels down the axon.
Cell Body: Contains the nucleus and maintains the cell's life processes.

Neurotransmitters

Acetylcholine: Important for memory and muscle control.
Endorphins: Involved in pain relief and feelings of pleasure.
Agonist: Enhances the effect of neurotransmitters.
Antagonist: Blocks or dampens the effect of neurotransmitters.
Oversupply of neurotransmitters: Can lead to conditions like schizophrenia.
Undersupply of neurotransmitters: Linked to disorders such as depression.

Nervous System

Central Nervous System (CNS): Comprises the brain and spinal cord.
Peripheral Nervous System: Connects the CNS to the rest of the body.
Somatic System: Controls voluntary movements.
Autonomic System: Regulates involuntary functions; subdivided into sympathetic (fight or flight) and parasympathetic (rest and digest).

Endocrine System

Adrenal Glands: Release hormones in response to stress.
Pituitary Glands: Often referred to as the "master gland," regulates other endocrine glands.

Brain Structure

Forebrain: Associated with advanced functions like reasoning and emotion.
Midbrain: Connects forebrain and hindbrain, involved in sensory processes.
Hindbrain: Controls basic life functions.
Key Structures: Pons, Medulla, Thalamus, Reticular Formation, Cerebellum, Limbic system (Amygdala, Hypothalamus, Hippocampus).

Cerebral Cortex and Hemispheres

Cerebral Hemispheres: Left and right sides of the brain, each responsible for different functions.
Lobes: Frontal (decision-making), Parietal (sensory), Occipital (vision), Temporal (auditory).
Motor Cortex: Controls voluntary movements; mapped to specific body parts.
Somatosensory Cortex: Processes sensory information from the body.
Neuroplasticity: The ability of the brain to reorganize itself by forming new neural connections.

Research on Twins

Twin Studies: Investigate the relative contributions of genetics and environment.
Identical Twins: Develop from the same fertilized egg, sharing identical genetics.
Fraternal Twins: Develop from separate eggs; genetically similar as siblings.
Separated Twins: Comparative studies of twins raised apart, assessing environmental impacts.
Epigenetics: Studies changes in gene expression based on environmental factors.

Psychology, Biology, and Change

Psychology is dynamic and constantly evolving, unlike biology which remains relatively unchanged.
Biblical references: Genesis 1:27 emphasizes human uniqueness, while 1 Thessalonians 5:19-21 addresses the importance of discernment.

The Empirical Approach

Psychology uses an empirical method, grounded in observation and experimentation.
Empirical exploration seeks to understand behavior and mental processes without bias or deception.
A scientific attitude is essential, which includes three main components: curiosity, skepticism, and humility.

Curiosity

Curiosity represents a deep desire to investigate and comprehend the world.
Facts must drive understanding; an empirical framework allows objective conclusions to emerge.

Curious Skepticism

Skeptical inquiry promotes critical questioning of behaviors and thoughts, encouraging deeper understanding.
Key questions to consider: "What do you mean?" and "How do you know?" assist in clarifying concepts.

Humility

Humility involves recognizing personal limitations and being open to correction and new ideas.
The principle of humility encourages an acceptance of being wrong and adaptability in thought.
One guiding principle in psychology is "The rat is always right," reflecting the importance of empirical validity in experimental setups.
