Piaget's Cognitive Development Theory Quiz

Chromosomes and Genes

• Human cells, excluding gametes, have 23 pairs of chromosomes.
• DNA is the building block of chromosomes.
• Genes are sections within chromosomes, providing instructions for structures.
• Gametes (sperm and ovum) have 23 chromosomes each.
• When sperm and ovum combine, they form 23 pairs of chromosomes.
• The 23rd chromosome pair determines chromosomal sex.

Sex Chromosomes

• Female sex chromosomes are XX.
• Male sex chromosomes are XY.
• One X chromosome comes from each biological parent.
• One Y chromosome comes from the biological father.

Stages of Prenatal Development

• Germinal Stage (Weeks 1-2): Conception occurs when sperm fertilizes an egg, forming a zygote.
• Embryonic Stage (Weeks 3-8): Cell implantation in the uterus; development of brain, heart, and other organs.
• Fetal Stage (Weeks 9-40): Development of sex organs. Specific developmental milestones occur during different weeks of the fetal stage (e.g., organ differentiation, brain growth).

Development Work

• Development can be continuous (gradual) or discontinuous (discrete steps).
• Nature (genetics) and nurture (environment) both influence development.

Infancy and Childhood Development

• The newborn (infant) experiences rapid physiological changes and development in the first few weeks.
• The baby's respiratory system begins functioning right after birth.
• Baby is born with fat for nutrient storage.
• Infants use preferential looking and habituation to learn.
• Reflexes are involuntary, automatic behaviors.
• Examples: grasping, Moro (startle), rooting, stepping, and sucking reflexes.

Brain Development: First 3 Years

• The brain experiences rapid growth due to increasing connectivity between neurons.
• Simultaneously, pruning (removing unused connections) occurs.

Sensations in Infancy

• Taste and smell are well-developed senses in infants, especially a preference for sweet tastes.
• Hearing is fairly developed at birth.
• Vision is the least developed sense at birth; it takes time for cones to fully develop, resulting in poor color vision and blurry vision initially. Infants focus better on immediate objects and show preferences for complex stimuli.

Cognitive Development

• Piaget's Theory: Cognitive development occurs in stages. Stages include: sensorimotor, preoperational, concrete operational, and formal operational.
• Vygotsky's Theory: Emphasizes social interaction in cognitive development; learning happens through scaffolding.
• Psychosocial Development: Importance of experiences related to social relationships.
• Temperament: Individual differences in emotional reactivity and self-regulation.
• Attachment: Close bonds between caregiver and child. Four attachment types exist: secure, avoidant, resistant, and disorganized.
• Self-concept: Development of awareness about oneself. This is assessed, for example, using the mirror test for self-recognition.
• Erikson's Theory: Psychosocial development across an entire lifespan. Tasks/conflicts must be resolved to develop a sense of competency.

Piaget's Cognitive Theory of Development

• Stages are qualitatively different, not just gradual differences.
• Schema are concepts used to categorize and interpret information.
• Assimilation occurs when new information is integrated with existing schema.
• Accommodation describes when existing schema change due to new information.

Piaget's Stages of Cognitive Development (summary)

• Sensorimotor (0–2 years): Experiencing the world through senses and actions (e.g., object permanence, stranger anxiety).
• Preoperational (2–6 years): Using words and images to represent things but lacking logical reasoning (e.g., pretend play, egocentrism).
• Concrete operational (7–11 years): Understanding concrete events and analogies logically, performing arithmetical operations (e.g., conservation, mathematical transformations).
• Formal operational (12+ years): Utilizing abstract reasoning.

Piaget's Sensorimotor Stage

• Mode of learning: sensations of acting on objects.
• Object permanence: understanding that objects continue to exist when out of sight.
• Stranger anxiety: develops around the development of object permanence.

Piaget's Preoperational Stage

• Symbolic representation; using symbols to represent words, images, and ideas.
• Language development
• Difficulty with conservation (understanding that quantity remains the same despite changes in appearance).
• Egocentrism (difficulty taking another person's perspective).

Piaget's Concrete Operational Stage

• Logical thought about concrete events.
• Mastery of mathematical operations (addition, subtraction).
• Conservation: understanding that quantity remains the same despite changes in shape or arrangement.
• Reversibility: understanding that actions can be reversed.

Piaget's Formal Operational Stage

• Abstract and hypothetical thought.
• Problem-solving and testing solutions.
• Renewed egocentrism (belief that others share one's perspective).

Vygotsky's Theory

• Social interaction is crucial for cognitive development.
• Scaffolding is the process where mentors provide support to help a learner achieve tasks. This support is gradually reduced.
• Importance of human interaction in cognitive and social development (in contrast to Piaget's focus on interaction with objects).

Temperament

• Innate traits affecting behavior, emotion, and reaction to the environment.
• There are different temperament styles: (e.g., easy, difficult).

Attachment

• Long-standing connection or bond with others.
• Measured using the "Strange Situation" experiment.
• Attachment types: secure, avoidant, resistant, and disorganized.

Self-Concept

• Understanding of oneself
• Assessed through tests such as the mirror test.

Erikson's Psychosocial Development Theory

• Emphasis on social nature of development, not just sexual.
• Development proceeds through eight stages throughout the lifespan.
• At each stage, a conflict or task must be resolved to develop a sense of competency.
• Failure to resolve these conflicts may result in feelings of inadequacy.

Adolescence

• Puberty initiates adolescence.
• Secondary sex characteristics develop.
• Growth spurt (starts and ends at different ages for females compared to males).
• Feeling of pride and/or embarrassment due to physical changes.
• Feelings of self-consciousness.
• Brain is not fully developed.
• Consequences of incomplete frontal lobe development related to judgment and decision-making.

Cognitive Development (Adolescence)

• Abstract thinking is developed.
• Theory of mind (understanding other people’s perspectives) develops.
• Cognitive empathy (ability to take the perspective or others and feel concern for them.) is more developed.

Kohlberg's Moral Reasoning Stages

• Preconventional (level 1): Morality is based on avoiding punishment or seeking rewards.
• Conventional (level 2): Morality is based on social approval and doing what is expected.
• Postconventional (level 3): Morality is based on universal ethical principles.

Adulthood

• Middle adulthood (40s–60s): Physical decline is gradual (e.g., skin elasticity, eyesight, sensory changes).
• Late adulthood (60+): Physical decline accelerates. (e.g., memory loss, cognitive changes).

Parenting Styles

• Authoritarian: High value placed on conformity and obedience. Rigid and less warmth to the child.
• Authoritative: Give children reasonable demands and limits, but also expression warmth and affection, and listening.
• Permissive: Few demands and infrequent punishment.
• Permissive neglectful: lack of structure, ignoring the child.
• Permissive indulgent: too much involvement with the child.

Theories of Physical and Psychological Aging

• Cellular clock theory: Limited number of cell reproductions to repair damages caused by aging.
• Wear and tear theory: External factors cause wear and tear (e.g., free radicals).
• Free radical theory: Free radicals accumulate, damaging cells and tissues.
• Activity theory: "Actively used iron does not rust".

About Mortality: Five Stages of Grief

• Denial, Anger, Bargaining, Depression, and Acceptance.
