Study Notes

Chapter 1: Introduction to Psychology

Psychology is the scientific study of the mind and behavior.
The mind encompasses mental processes like thoughts, feelings, perceptions.
Behavior involves observable actions and reactions.
The scientific approach utilizes empirical methods (measurable and observable evidence).
Key concepts include the empirical approach and the scientific process: hypothesizing, collecting data, testing hypotheses, drawing conclusions.
Fields of study include the human brain, consciousness, memory, language, reasoning, personality, and mental health.

Historical and Contemporary Schools of Thought

Structuralism (Wundt, Titchener): Focused on breaking down mental processes into basic elements using introspection (self-observation). Limitations included subjectivity.
Functionalism (James): Emphasized the function of consciousness in adaptation, influenced by Darwin's theory. Focused on the whole mind, broader than structuralism.
Psychoanalytic Theory (Freud): Emphasized the unconscious mind's role in behavior using methods like dream analysis and free association. Believed early experiences shape unconscious conflicts.
Gestalt Psychology (Kohler, Koffka, Wertheimer): Argued perception is more than the sum of its parts. Examples include how a song differs from its individual notes.
Behaviorism (Pavlov, Watson, Skinner): Focused solely on observable behaviors, rejecting the study of consciousness. Methods included classical conditioning (learning through associations) and operant conditioning (learning through reinforcement). The Little Albert experiment demonstrated learned phobias.
Humanism (Rogers, Maslow): Emphasized inherent human goodness and self-improvement. Key concepts include client-centered therapy (empathy, genuineness, unconditional positive regard) and Maslow's Hierarchy of Needs.
Cognitive Revolution (Chomsky): Returned to studying mental processes (thoughts, memory, language) influenced by linguistics and computer science.

Differences Between Psychological Perspectives

These differing perspectives offer various ways to study the human mind and behaviour and explain how we think, feel, and act.

Differences Between Areas of Psychology

Various areas within psychology, each with a specific focus and methodology. Examples: biopsychology, evolutionary psychology, sensation and perception, cognitive psychology, developmental psychology, personality psychology, social psychology, clinical psychology, health psychology, industrial-organizational psychology, and forensic psychology. Each explores different aspects of human experience and behavior.

Psychology's Empiricism

Psychology relies on empirical methods (observable, testable evidence).
Research steps include observation, hypothesis generation, data collection, analysis, and conclusion drawing.
Psychologists observe behaviors in naturalistic or controlled settings.

Chapter 2: Research Methods in Psychology

Correlation and Causation

Correlation describes a statistical relationship between variables (positive, negative, or none).
A correlation coefficient (r) measures the strength and direction (-1 to +1).
Correlation does not equal causation—experiments are needed to establish cause-and-effect.
Confounds (extraneous variables) can influence observed relationships.

Research Methods

Naturalistic observation: Observing behavior in natural settings.
Lab observation: Observing behavior in a controlled setting.
Case studies: In-depth studies of individuals.
Surveys: Gathering data from many individuals using questionnaires.
Archival data: Using existing records to study relationships.
Experiments: Manipulating an IV to measure its effect on a DV.
Different design types – longitudinal vs cross-sectional studies – random and representative samples.

Variables

Independent Variable (IV): The manipulated variable in experiments.
Dependent Variable (DV): The measured outcome in experiments.
Control variables: factors kept constant to avoid bias in experimental design.
Confounding variables: uncontrolled variables that affect both IV and DV, can lead to false conclusions.

Chapter 3: Biological Basis of Behavior

Neuron Structure and Function

Neurons are basic units of the nervous system—sending signals.
Neuron structures (soma, dendrites, axon, myelin sheath, nodes of Ranvier, terminal buttons) serve specific functions in signal transmission.

Nervous System Divisions

The nervous system comprises the central nervous system (CNS) and the peripheral nervous system (PNS).
The PNS has the somatic (voluntary movement) and autonomic (involuntary functions) divisions, further divided into sympathetic (arousal) and parasympathetic (calm) branches.
Sensory and motor nerves carry specific information.

Central Nervous System (CNS)

The CNS includes the brain, spinal cord—control center for body—reflexes, sending signals to the body from the brain, and spinal cord.

Brain Structures

The brain is divided into regions—forebrain, midbrain, and hindbrain—each with specific functions.
Forebrain structures include the cerebral cortex (higher-level functions), thalamus (relay center), hypothalamus (regulates drives), amygdala (emotion), hippocampus (memory).
Midbrain structures include the reticular formation (alertness), substantia nigra and VTA (movement and reward).
Hindbrain structures include the medulla (breathing, heartbeat), pons (sleep and arousal), and cerebellum (balance and coordination).

Brain Lobes

The cerebral cortex is divided into four lobes (frontal, parietal, occipital, temporal).
Each lobe performs certain functions.

Brain Imaging Techniques

Various techniques exist to study the brain (e.g., CT, PET, MRI, fMRI, EEG) Each offering different ways to understand brain activity and its relationship to different functions.

Chapter 4: Sleep and Consciousness

Theories of Sleep

Adaptive theory (sleep protects from predators).
Restorative theory (sleep allows for repair and restoration of the body).

Theories of Dreaming

Wish fulfillment (Freud's theory that dreams express unconscious desires).
Information-processing (dreams help process daily experiences).
Activation-synthesis (dreams are byproducts of random brain activity).

Sleep Disorders

Insomnia, sleepwalking, sleep apnea, narcolepsy, night terrors are examples of sleep disorders with specific symptoms.

Consciousness and Altered States

Consciousness is awareness of oneself and the environment.
Altered states include sleep, daydreaming, hypnosis, meditation, and drug-induced states each creating varied experiences, changes in perception, and mental states.

Brain Waves During Sleep

Different brain wave patterns (alpha, theta, delta, beta-like) are associated with various stages of sleep (NREM stages 1,2,3, and REM).

Sleep Cycles

Sleep progresses through recurring cycles of NREM and REM sleep.
Each cycle lasts about 90-110 minutes.

Effects of Sleep Deprivation

Sleep deprivation has physical, cognitive, and emotional consequences.

Biological Rhythms

Biological rhythms, like the circadian rhythm, influence sleep and other bodily functions.
The suprachiasmatic nucleus (SCN) and melatonin regulate sleep-wake cycles.
