Study Notes
Propositions and Compound Propositions
- A proposition is a declarative statement that can be either true or false, but not both.
- Compound propositions combine two or more propositions.
Truth Value
- Represents the truth or falsity of a statement, denoted by T (true) or F (false).
Logical Variables
- Statements are represented by lowercase letters (p, q, r, s, etc.).
- The number of possible truth values for a set of propositions is calculated as 2^n, where 'n' represents the number of propositions.
Logical Operations
- Negation (not) - The opposite of the proposition, symbolized by ¬.
- Conjunction (and) ∧ - Connects propositions using the word "and."
- Disjunction (or) ∨ - Connects propositions using the word "or."
- Conditional Statement / Implication (if and then) (implies) - Represents an implication "if p then q."
- Converse - Switches the hypothesis (p) and conclusion (q) of a conditional statement.
- Inverse - Negates both the hypothesis and conclusion of a conditional statement.
- Contrapositive - Negates both the hypothesis and conclusion of the converse statement.
- Bi-conditional Statement (Bi-Implication) - Combines two conditional statements using "if and only if."
Thomistic Ethics
- A moral philosophy developed by St. Thomas Aquinas.
- Emphasizes reason as the source of moral law, guiding us towards the good.
- The ultimate goal is to achieve the good, which is discoverable by our nature.
- Key principle : "to do good, avoid evil."
- Actions are considered right if they align with moral law, which is dictated by reason.
- Moral law originates from eternal and divine law.
- Actions are good if they are in accordance with human nature and aligned with our conscience, which serves as a guide for making moral decisions.

Intraphysic Conflict
- Refers to psychological conflict within an individual's mind, often stemming from competing desires, values, or motivations.
- Arise from interactions between the Id, Ego, and Superego.
Coping Mechanisms
- Strategies used to reduce anxiety, but excessive reliance on them can hinder personal growth.
- Repression: Unconsciously pushing unpleasant thoughts or memories out of awareness.
- Denial: Refusing to accept reality or facts.
- Projection: Attributing one's own unwanted feelings or thoughts to someone else.
- Rationalization: Justifying actions with logical explanations to avoid uncomfortable emotions.
- Displacement: Redirecting emotions from a threatening target to a safer one.
- Sublimation: Channeling negative emotions into positive activities.
Erik Erikson's Psychosocial Stages of Development
- Describes the stages of psychosocial development, emphasizing the interaction of opposites and the potential for a basic strength or core pathology at each stage.
- Infancy: Trust vs. Mistrust (0-2 years old): The first stage, where trust is built through consistent care from the mother.
- Early Childhood: Autonomy vs. Shame and Doubt (2-4 years old): This stage focuses on developing independence and self-reliance, where children learn to explore and control their environment.
- Play Age: Initiative vs. Guilt (4-6 years old): This stage encourages children to become active and explore their world, learning goal setting and responsibility.
- School Age: Industry vs. Inferiority (6-12 years old): This stage centers on children's expanding social world, requiring them to learn new skills and adapt to new demands.
- Adolescence: Identity vs. Identity Confusion (12-18 years old): The most crucial developmental stage, where individuals must define their own identity and sense of self.
- Young Adulthood: Intimacy vs. Isolation (19-30 years old): This stage emphasizes the development of intimate relationships, requiring vulnerability and commitment.
- Adulthood: Generativity vs. Stagnation (30-65 years old): This stage focuses on finding meaning and purpose in life, often through contributions to society and the next generation.
- Old Age: Ego Integrity vs. Despair (65 years and older): This final stage involves reflecting on one's life with a sense of fulfillment or regret.
Jean Piaget's Cognitive Development Theory
- Describes how cognitive skills evolve through stages, with each stage characterized by qualitative differences in thinking.
- Focuses on children's intellectual development.
- Introduces schemas as the basic building blocks of knowledge.
- Cognitive development is driven by the need for adaptation and equilibrium.
Sensorimotor Stage (0-2 Years Old)
- The first stage of cognitive development, where infants learn through sensory experiences and motor actions.
Vision
- Threshold: The minimum amount of stimulus needed to excite a receptor.
- Vision: The range of wavelengths visible varies from 400 to 800 millimicrons.
Layers of the Human Eye
- Sclerotic Coat: The white of the eye, maintaining shape and providing protection.
- Choroid Coat: Supplies the outer retina with nutrients, maintaining temperature and volume.
- Retina: Detects light and converts it into signals for the brain.
Light Receptors and Signal Transduction
- Rods: Sensitive to light.
- Cones: Sensitive to color.
Vision Problems
- Fovea Centralis: The area of the retina with the clearest vision.
- Blind Spot: The point where the optic nerve ends, lacking rods and cones.
- Myopia: Nearsightedness (inability to see far).
- Hyperopia: Farsightedness (inability to see near).
- Presbyopia: Age-related inability to focus on near objects.
- Astigmatism: Irregularity in the shape of the cornea.
- Retinal Disparity: Difference in images between the two eyes.
Dark Adaptation
- The process by which the eyes adjust to low levels of illumination.
Purkinje Phenomenon
- The shift in the relative brightness of colors as the intensity of illumination changes.
Color

Theories of Vision
- Young-Helmholtz Theory: Tiny cells in the eye receive light waves and translate them into one of three colors (blue, green, and red).
- Hering Theory (Opponent-Process Theory): The appearance of any color is explained by the extent to which it is red vs. green, blue vs. yellow, or black vs. white.
Taste Sensitivity
- Decreases with age and is reduced by smoking.
Cutaneous Sensitivities (Touch)
- Pressure: Hairbulbs, Meissner's corpuscles, and Merkel corpuscles are responsible for pressure perception.

- Muscle Sense: The ability to coordinate movements by sending signals to the brain.
Perception
- Combines sensory information and past experiences to recognize objects or situations.
Attention
- The ability to focus on specific stimuli in the environment, influenced by factors like intensity, change, and repetition.
Types of Sets
- Motor Set: The body is prepared to react based on anticipated stimuli (e.g., waiting for a signal to leave).
- Perceptual Set: The mind is prepared to notice specific stimuli (e.g., a hungry person noticing restaurant signs).
- Mental Set: The mind is prepared to think about situations in a particular way.

- Intense Stimuli: Strong stimuli are more noticeable (e.g., bright colors).
- Changing Stimuli: Things that change, like flickering lights, attract attention
- Repeated Stimuli: Repetition helps capture attention
- Contrasting Stimuli: Something that stands out from its surroundings is more noticeable (e.g., a black sheep among white sheep).
