Basic Algebra Study Guide

Introduction to Algebra

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In algebra, letters (variables) represent numbers in equations and expressions, allowing for the formulation of general rules and relationships.

Core Concepts

1. Variables: Symbols (like x, y, z) that represent unknown values.

2. Constants: Fixed values (like 2, -5, 3.14).

3. Expressions: Combinations of variables and constants using operations (such as addition, subtraction, multiplication, and division).

• Example: (3x + 4 - 2y)

1. Equations: Statements that two expressions are equal, often containing an equal sign (=).

• Example: (2x + 3 = 7)

1. Terms: Individual parts of an expression or equation, separated by + or - signs.

• Example: In (3x + 4 - 2y), the terms are (3x), (4), and (-2y).

1. Coefficients: The numerical factor in a term that contains a variable.

• Example: In (7x), 7 is the coefficient.

1. Order of Operations: The rules that determine the sequence in which calculations are performed. The acronym PEMDAS can help remember this:

• Parentheses
• Exponents
• Multiplication and Division (left to right)
• Addition and Subtraction (left to right)

Core Formulas

1. Solving for a Variable:

• To isolate (x) in an equation like (ax + b = c): [ x = \frac{c - b}{a} ]

1. The Distributive Property:

• Used to multiply a single term by each term within a parentheses: [ a(b + c) = ab + ac ]

1. Factoring:

• To express an expression as a product of its factors. For example, to factor (x^2 - 9): [ x^2 - 9 = (x - 3)(x + 3) ]

1. Quadratic Formula (for solving (ax^2 + bx + c = 0)): [ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ]

Example Problems

1. Solving a Linear Equation: [ 2x + 3 = 7 ] Solution: [ 2x = 7 - 3 \implies 2x = 4 \implies x = \frac{4}{2} = 2 ]

2. Applying the Distributive Property: [ 5(3x + 2) = ? ] Solution: [ = 15x + 10 ]

3. Factoring an Expression: [ x^2 + 5x + 6 ] Solution: Find two numbers that multiply to 6 and add to 5. The numbers are 2 and 3. [ = (x + 2)(x + 3) ]

4. Using the Quadratic Formula: [ x^2 + 4x + 3 = 0 ] Here, (a = 1), (b = 4), (c = 3). Solution: [ x = \frac{-4 \pm \sqrt{4^2 - 4 \cdot 1 \cdot 3}}{2 \cdot 1} = \frac{-4 \pm \sqrt{16 - 12}}{2} = \frac{-4 \pm \sqrt{4}}{2} = \frac{-4 \pm 2}{2} ] This gives two solutions: [ x = \frac{-2}{2} = -1 \quad \text{and} \quad x = \frac{-6}{2} = -3 ]

Practice Problems

1. Solve the equation: (3x - 5 = 16).
2. Distribute and simplify: (7(2x - 3) + 4).
3. Factor the expression: (x^2 - 7x + 10).
4. Use the quadratic formula to solve: (2x^2 - 4x - 6 = 0).

Answers to Practice Problems

1. (x = 7)
2. (14x - 21 + 4 = 14x - 17)
3. ((x - 2)(x - 5))
4. (x = 3 \; \text{or} \; x = -1)

This guide covers fundamental concepts in basic algebra. Remember to practice regularly to solidify your understanding!

I. Number Systems & Properties:

• Real Numbers: Include all rational (integers, fractions, decimals) and irrational (non-repeating, non-terminating decimals like π) numbers.
• Integers: Whole numbers and their opposites (… -3, -2, -1, 0, 1, 2, 3 …)
• Rational Numbers: Numbers that can be expressed as a fraction a/b, where a and b are integers and b ≠ 0.
• Irrational Numbers: Numbers that cannot be expressed as a fraction.
• Properties:
  • Commutative Property: a + b = b + a; a * b = b * a
  • Associative Property: (a + b) + c = a + (b + c); (a * b) * c = a * (b * c)
  • Distributive Property: a(b + c) = ab + ac; a(b - c) = ab - ac
  • Identity Property: a + 0 = a; a * 1 = a
  • Inverse Property: a + (-a) = 0; a * (1/a) = 1 (a ≠ 0)

Example Problem: Simplify 2(x + 3) - 4x using the distributive property. Solution: 2(x + 3) - 4x = 2x + 6 - 4x = -2x + 6

II. Variables & Expressions:

• Variables: Letters representing unknown values (e.g., x, y, z).
• Expressions: Combinations of numbers, variables, and operations (e.g., 3x + 5, 2y - 7).
• Terms: Parts of an expression separated by + or - signs (e.g., in 3x + 5, 3x and 5 are terms).
• Coefficients: Numbers multiplying variables (e.g., in 3x, 3 is the coefficient).
• Constants: Terms without variables (e.g., in 3x + 5, 5 is the constant).

Example Problem: Identify the terms, coefficients, and constants in the expression 4x² - 2x + 7. Solution: Terms: 4x², -2x, 7; Coefficients: 4, -2; Constants: 7

III. Equations & Solving Equations:

• Equations: Statements showing two expressions are equal (e.g., 2x + 3 = 7).
• Solving Equations: Finding the value(s) of the variable that make the equation true. Use inverse operations to isolate the variable.
• Linear Equations: Equations where the highest power of the variable is 1 (e.g., 3x + 2 = 8).

Example Problem: Solve the equation 2x + 5 = 11. Solution:

1. Subtract 5 from both sides: 2x = 6
2. Divide both sides by 2: x = 3

IV. Inequalities:

• Inequalities: Statements comparing two expressions using < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to).
• Solving Inequalities: Similar to solving equations, but remember to reverse the inequality sign when multiplying or dividing by a negative number.

Example Problem: Solve the inequality 3x - 6 > 9. Solution:

1. Add 6 to both sides: 3x > 15
2. Divide both sides by 3: x > 5

V. Graphing Linear Equations:

• Slope-Intercept Form: y = mx + b, where m is the slope and b is the y-intercept.
• Slope: The steepness of a line (rise/run).
• Y-intercept: The point where the line crosses the y-axis.

Example Problem: Graph the equation y = 2x + 1. Solution: The y-intercept is 1. The slope is 2 (or 2/1), meaning for every 1 unit increase in x, y increases by 2 units.

VI. Exponents and Powers:

• Exponents: Indicate repeated multiplication (e.g., x³ = x * x * x).
• Power: The entire expression (base raised to an exponent, e.g., x³).
• Rules of Exponents:
  • xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾
  • xᵃ / xᵇ = x⁽ᵃ⁻ᵇ⁾
  • (xᵃ)ᵇ = x⁽ᵃ*ᵇ⁾
  • x⁰ = 1 (x ≠ 0)

Example Problem: Simplify x⁵ * x². Solution: x⁽⁵⁺²⁾ = x⁷

VII. Order of Operations (PEMDAS/BODMAS):

• Parentheses/Brackets: Perform operations within parentheses first.
• Exponents/Orders: Evaluate exponents.
• Multiplication and Division: Perform from left to right.
• Addition and Subtraction: Perform from left to right.

Example Problem: Evaluate 3 + 2 * 4 - 1² Solution: 3 + 8 - 1 = 10

Certainly! Here's a study guide for understanding the human digestive system, focusing on the main organs and their functions:

Human Digestive System Study Guide

The human digestive system is a complex series of organs and glands that processes food. It involves a coordinated series of actions that break down food into nutrients, which the body uses for energy, growth, and cell repair.

1. Mouth

• Function:
• Begins the digestive process through mechanical digestion (chewing) and chemical digestion (saliva).
• Saliva contains the enzyme amylase, which starts breaking down carbohydrates.

2. Pharynx and Esophagus

• Pharynx:
• Acts as a pathway for the movement of food from the mouth to the esophagus.
• Esophagus:
• A muscular tube that connects the pharynx to the stomach.
• Function: Transports food using a series of muscular contractions called peristalsis.

3. Stomach

• Function:
• Stores, mixes, and further digests food with gastric juices.
• Secretes hydrochloric acid and digestive enzymes (e.g., pepsin) to break down proteins.
• Converts food into a semi-liquid form called chyme.

4. Small Intestine

• Divided into three parts: duodenum, jejunum, and ileum.
• Duodenum:
• Receives chyme from the stomach, along with bile from the gallbladder and digestive enzymes from the pancreas.
• Function (overall):
• Main site for chemical digestion and nutrient absorption.
• Enzymes continue the breakdown of food, and nutrients are absorbed into the bloodstream through the intestinal walls.

5. Pancreas

• Function:
• Produces digestive enzymes (like lipase, protease, and amylase) and bicarbonate, which neutralize stomach acid and enhance digestion.
• Regulates blood sugar by producing insulin and glucagon.

6. Liver

• Function:
• Produces bile, which is stored in the gallbladder and helps emulsify fats in the small intestine.
• Processes and detoxifies substances absorbed from the digestive tract.
• Metabolizes nutrients and stores glucose as glycogen.

7. Gallbladder

• Function:
• Stores and concentrates bile produced by the liver.
• Releases bile into the small intestine to aid in the digestion of fats.

8. Large Intestine (Colon)

• Divided into the cecum, colon, rectum, and anal canal.
• Function:
• Absorbs water and electrolytes from the remaining indigestible food matter.
• Transforms waste into feces for excretion.
• Houses microbiota that supports digestion.

9. Rectum and Anus

• Rectum:
• Stores feces until they are expelled.
• Anus:
• Regulates the excretion of feces from the body.

Key Concepts:

• Peristalsis: Wave-like muscle contractions that move food through the digestive tract.
• Enzymatic Activity: Enzymes play a critical role in breaking down complex molecules into absorbable nutrients.
• Nutrient Absorption: Primarily occurs in the small intestine, where digested nutrients pass through the intestinal wall into the bloodstream.
• Waste Elimination: The large intestine plays a crucial role in reabsorbing water and forming waste products (feces) for removal.

Review Questions:

1. How does the stomach protect itself from its own acidic environment?
2. What role does the pancreas play in regulating blood glucose levels?
3. Describe the process of fat digestion and the organs involved.
4. What is the significance of intestinal microbiota?

Use this guide as a starting point for a deeper exploration of the human digestive system, focusing on each organ's unique role in processing and absorbing nutrients.

Human Digestive System Study Guide

Major Organs & Functions

1. Mouth

• Mechanical breakdown of food through chewing
• Contains salivary glands that release enzymes
• Enzyme amylase begins carbohydrate breakdown
• Forms food into bolus

2. Esophagus

• Muscular tube connecting mouth to stomach
• Uses peristalsis to move food downward
• Contains sphincter to prevent food backup

3. Stomach

• Secretes gastric juices and HCl acid
• Breaks down proteins with pepsin
• Churns food into semi-liquid chyme
• Kills harmful bacteria
• Releases food gradually into small intestine

4. Small Intestine

• Major site of nutrient absorption
• Three sections: duodenum, jejunum, ileum
• Contains villi for increased surface area
• Receives enzymes from pancreas
• Receives bile from liver/gallbladder

5. Liver

• Produces bile for fat breakdown
• Detoxifies harmful substances
• Stores vitamins and minerals
• Processes nutrients from blood
• Creates plasma proteins

6. Gallbladder

• Stores and concentrates bile
• Releases bile when fatty foods present

7. Pancreas

• Produces digestive enzymes
• Releases insulin and glucagon
• Neutralizes stomach acid

8. Large Intestine

• Absorbs water and minerals
• Houses beneficial bacteria
• Forms and stores feces
• Produces some vitamins (K, B)

Key Functions of Digestive System

1. Ingestion
2. Mechanical digestion
3. Chemical digestion
4. Absorption
5. Elimination

Human Digestive System Study Guide

This guide outlines the major organs and their functions within the human digestive system.

I. Overview:

The digestive system is responsible for breaking down food into absorbable nutrients that the body uses for energy, growth, and repair. This process involves both mechanical and chemical digestion.

II. Key Processes:

• Ingestion: Taking food into the mouth.
• Digestion: Breaking down food mechanically and chemically.
• Absorption: Nutrients passing from the digestive tract into the bloodstream.
• Elimination: Removing undigested waste.

III. Major Organs and their Functions:

A. The Alimentary Canal (Gastrointestinal Tract): A continuous tube running from the mouth to the anus.

1. Mouth:

   • Function: Begins mechanical digestion through chewing (mastication) and chemical digestion through saliva containing the enzyme amylase (breaks down carbohydrates).
   • Key Structures: Teeth, tongue, salivary glands.

2. Pharynx (Throat):

   • Function: Propels food from the mouth to the esophagus.
   • Key Structures: Epiglottis (prevents food from entering the trachea).

3. Esophagus:

   • Function: Transports food from the pharynx to the stomach through peristalsis (muscular contractions).

4. Stomach:

   • Function: Continues mechanical digestion through churning and chemical digestion through gastric juices containing hydrochloric acid (HCl) and pepsin (breaks down proteins). The stomach also stores food temporarily.
   • Key Structures: Cardiac sphincter (controls entry), pyloric sphincter (controls exit), gastric glands.

5. Small Intestine:

   • Function: Primary site of nutrient absorption. Chemical digestion continues with enzymes from the pancreas and small intestine itself.
   • Key Structures: Duodenum (receives chyme, bile, and pancreatic enzymes), jejunum (major site of absorption), ileum (absorbs remaining nutrients, vitamin B12, and bile salts). Villi and microvilli increase surface area for absorption.

6. Large Intestine (Colon):

   • Function: Absorbs water and electrolytes, forms and stores feces.
   • Key Structures: Cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, anus.

Digestive Process

1. Food enters the mouth, where it is broken down through chewing and mixing with saliva.
2. The food is then swallowed and transported through the esophagus to the stomach.
3. In the stomach, the food is further broken down by digestive enzymes and acids.
4. The partially digested food is then released into the small intestine, where nutrients are absorbed into the bloodstream.
5. The remaining waste products then move into the large intestine, where water and electrolytes are absorbed and the waste is stored until elimination.
6. Finally, the waste products are eliminated from the body through the rectum and anus.

Key Terms

• Mastication: the process of breaking down food through chewing
• Peristalsis: the muscular contractions that move food through the digestive system
• Digestive enzymes: proteins that break down food into smaller particles

  • Neutrons: Neutrally charged, found in the nucleus, contribute to atomic mass (along with protons). Isotopes have the same number of protons but different numbers of neutrons.
  • Electrons: Negatively charged, orbit the nucleus in energy levels/shells, determine chemical reactivity.

• Electron Configuration: The arrangement of electrons in an atom's energy levels. Follows specific rules (Aufbau principle, Hund's rule, Pauli exclusion principle). Notation examples: 1s²2s²2p⁶ or [Ne]3s². Valence electrons are the outermost electrons and are crucial for bonding.

• Atomic Number (Z): Number of protons in an atom's nucleus. Defines the element.

• Mass Number (A): Sum of protons and neutrons in an atom's nucleus.

• Isotopes: Atoms of the same element with different numbers of neutrons. Example: Carbon-12 (6 protons, 6 neutrons) and Carbon-14 (6 protons, 8 neutrons).

• Ions: Atoms that have gained or lost electrons, resulting in a net electrical charge. Cations are positively charged (lost electrons), anions are negatively charged (gained electrons).

II. Chemical Bonds

• Octet Rule: Atoms tend to gain, lose, or share electrons to achieve a full outer shell (usually 8 electrons, like noble gases).

• Types of Chemical Bonds:

  • Ionic Bonds: Formed by the transfer of electrons between a metal and a nonmetal. Results in the formation of ions held together by electrostatic attraction. Example: NaCl (sodium chloride).
  • Covalent Bonds: Formed by the sharing of electrons between two nonmetals. Can be single, double, or triple bonds. Example: H₂O (water).
    • Polar Covalent Bonds: Unequal sharing of electrons due to differences in electronegativity. Creates partial charges (δ+ and δ-). Example: H₂O.
    • Nonpolar Covalent Bonds: Equal sharing of electrons. Example: H₂.
  • Metallic Bonds: Formed by the sharing of electrons among a sea of metal atoms. Creates a "sea" of delocalized electrons, responsible for metallic properties like conductivity and malleability.

III. Periodic Table Trends

• Periods: Horizontal rows on the periodic table. Correspond to the principal energy level (n) being filled with electrons.

• Groups/Families: Vertical columns on the periodic table. Elements in the same group have similar chemical properties due to similar valence electron configurations.

• Key Trends (across a period, from left to right):

  • Atomic Radius: Decreases. Increased nuclear charge pulls electrons closer.
  • Ionization Energy: Increases. More difficult to remove an electron due to stronger nuclear attraction.
  • Electronegativity: Increases. Greater tendency to attract electrons in a bond.
  • Metallic Character: Decreases. Elements become less metallic and more nonmetallic.

• Key Trends (down a group, from top to bottom):

  • Atomic Radius: Increases. Adding more energy levels.
  • Ionization Energy: Decreases. Easier to remove an electron from a higher energy level.
  • Electronegativity: Decreases. Less tendency to attract electrons in a bond.
  • Metallic Character: Increases. Elements become more metallic.

IV. Key Terms and Concepts

• Characterized by high melting and boiling points, and typically soluble in water.
• Example: NaCl (sodium chloride).

B. Covalent Bonds

• Formed by the sharing of electrons between atoms.
• Can be polar (unequal sharing due to electronegativity differences) or nonpolar (equal sharing).
• Characterized by lower melting and boiling points compared to ionic compounds.
• Example: H₂O (water).

C. Metallic Bonds

• Formed by the attraction between metal atoms and the sea of delocalized electrons.
• Responsible for properties such as ductility, malleability, and electrical conductivity.

D. Bonding Theories

1. Valence Shell Electron Pair Repulsion (VSEPR): Predicts the geometry of molecular structures.
2. Hybridization: Mixing of atomic orbitals to form new hybrid orbitals.

• Example: sp³ hybridization in methane (CH₄).

III. Periodic Table Trends

A. Atomic Radius

• Trends: Decreases across a period (left to right) due to increased nuclear charge, and increases down a group due to additional electron shells.

B. Ionization Energy

• The energy required to remove an electron from an atom.
• Trends: Increases across a period (more protons increase attraction) and decreases down a group (electrons are further from the nucleus and experience shielding).

C. Electronegativity

• The ability of an atom to attract electrons in a chemical bond.
• Trends: Increases across a period and decreases down a group.
• Commonly measured in Pauling units; Fluorine is the most electronegative element.

D. Electron Affinity

• Atomic Mass: The weighted average of the masses of all naturally occurring isotopes of an element.
• Electron Configuration: The arrangement of electrons in an atom's energy levels and sublevels (s, p, d, f orbitals). Use the Aufbau principle, Hund's rule, and the Pauli exclusion principle to determine electron configurations.
• Valence Electrons: Electrons in the outermost shell of an atom; these are involved in chemical bonding.
• Ions: Atoms that have gained or lost electrons, resulting in a net positive (cation) or negative (anion) charge.

II. Chemical Bonds:

• Ionic Bonds: Formed through the electrostatic attraction between oppositely charged ions (cations and anions). Typically occur between metals and nonmetals. Characteristics include high melting points, brittleness, and the ability to conduct electricity when molten or dissolved in water.
• Covalent Bonds: Formed by the sharing of electrons between two atoms. Typically occur between nonmetals. Characteristics can vary widely depending on the molecule's structure and polarity. Include polar covalent bonds (unequal sharing) and nonpolar covalent bonds (equal sharing).
• Metallic Bonds: Formed by the delocalized sharing of electrons among a large number of metal atoms. Characteristics include high electrical and thermal conductivity, malleability, and ductility.
• Intermolecular Forces: Weak forces of attraction between molecules. These include:
  • London Dispersion Forces (LDFs): Weakest intermolecular force, present in all molecules.
  • Dipole-Dipole Forces: Occur between polar molecules.
  • Hydrogen Bonding: A special type of dipole-dipole interaction involving hydrogen bonded to a highly electronegative atom (N, O, or F).

III. Periodic Table Trends:

The periodic table organizes elements based on their atomic number and recurring properties. Key trends include:

• Electronegativity: The ability of an atom to attract electrons in a chemical bond. Increases across a period (left to right) and decreases down a group (top to bottom).
• Ionization Energy: The energy required to remove an electron from an atom. Increases across a period and decreases down a group.

I. Psychoanalytic Theories: Focus on the unconscious mind and early childhood experiences.

• A. Sigmund Freud's Psychosexual Stages: Personality develops through a series of stages where libido (psychic energy) is focused on different erogenous zones. Fixation at a stage can lead to specific personality traits.
  • 1. Oral (0-18 months): Pleasure from mouth (sucking, biting). Fixation: Oral receptive (dependent, passive) or Oral aggressive (sarcastic, hostile).
  • 2. Anal (18-36 months): Pleasure from bowel and bladder control. Fixation: Anal retentive (orderly, stingy) or Anal expulsive (messy, rebellious).
  • 3. Phallic (3-6 years): Pleasure from genitals; Oedipus/Electra complex. Fixation: Vanity, recklessness, or sexual dysfunction.
  • 4. Latency (6-puberty): Repressed sexual feelings; focus on social and intellectual skills.
  • 5. Genital (puberty onward): Mature sexuality; focus on intimate relationships.
• B. Carl Jung's Analytical Psychology: Emphasized the collective unconscious, a shared reservoir of archetypes (universal symbolic images). Personality types (introvert/extrovert) also play a role.
• C. Alfred Adler's Individual Psychology: Focused on striving for superiority and overcoming feelings of inferiority. Birth order and social context significantly influence personality.

II. Humanistic Theories: Emphasize human potential, self-actualization, and personal growth.

• B. Raymond Cattell's 16 Personality Factors: Used factor analysis to identify 16 source traits underlying personality.
• C. Hans Eysenck's Three Dimensions of Personality: Proposed three dimensions: extraversion-introversion, neuroticism-stability, and psychoticism-superego control.
• D. Five-Factor Model (Big Five): A widely accepted model proposing five core dimensions: Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (OCEAN).

IV. Social-Cognitive Theories: Emphasize the interaction between cognitive factors, behavior, and the environment.

• A. Albert Bandura's Social Learning Theory: Emphasized observational learning, self-efficacy (belief in one's ability), and reciprocal determinism (interaction between person, behavior, and environment).
• B. Julian Rotter's Locus of Control: Focuses on whether individuals believe they control their own destinies (internal locus of control) or are controlled by external forces (external locus of control).
• C. Walter Mischel's Cognitive-Affective Personality System (CAPS): Emphasizes the importance of situational variables and cognitive-affective units (encodings, expectancies, goals, etc.) in shaping behavior.

V. Biological Theories: Focus on the role of genetics and physiological factors in shaping personality.

• A. Temperament: Innate, biologically based dispositions that influence reactivity and self-regulation.
• B. Behavioral Genetics: Studies the heritability of personality traits.
• C. Evolutionary Psychology: Explores how evolutionary pressures have shaped personality characteristics.

Key Concepts to Review:

Psychology Study Guide: Major Theories of Personality Development

This study guide provides an overview of key theories related to personality development. Each theory encompasses distinct views on how personality is formed, shaped, and influenced throughout an individual’s life.

1. Psychodynamic Theory

• Key Contributor: Sigmund Freud
• Concepts:
  • Id, Ego, Superego: Components of personality. The id is primal instincts, the ego is the rational part that mediates, and the superego represents moral standards.
  • Defense Mechanisms: Strategies used by the ego to protect itself from anxiety and conflict (e.g., repression, denial, projection).
  • Stages of Psychosexual Development: Freud proposed five stages (oral, anal, phallic, latency, genital) during which personality develops as children encounter conflicts related to pleasure and social norms.
• Key Idea: Personality is largely influenced by unconscious processes and childhood experiences.

2. Neo-Freudian Theories

• Key Contributors: Carl Jung, Alfred Adler, Karen Horney, Erik Erikson
• Concepts/Contributions:
  • Carl Jung: Introduced concepts of the collective unconscious and archetypes, emphasizing the role of culture and society.
  • Alfred Adler: Focused on the concept of inferiority and striving for superiority, introducing the idea of the "inferiority complex" and the importance of social interest.
  • Karen Horney: Critiqued Freud’s theory, emphasizing social and cultural factors and the role of feminine psychology.
  • Erik Erikson: Proposed eight stages of psychosocial development, each characterized by a specific conflict that must be resolved (e.g., trust vs. mistrust, identity vs. role confusion).

3. Behavioral Theory

• Key Contributors: B.F. Skinner, John B. Watson
• Concepts:
  • Operant Conditioning: Skinner's theory that behavior is shaped by reinforcement and punishment. Personality develops through interaction with the environment.
  • Classical Conditioning: Watson’s approach that emphasizes associations between stimuli and responses.
• Key Idea: Personality is a result of learned behaviors and environmental influences, rather than inherited traits or innate drives.

4. Humanistic Theory

• Key Contributors: Carl Rogers, Abraham Maslow
