Lifespan Development: Cognitive and Social Flashcards
Cognitive Development in Early Adulthood (18–40)
Cognitive Peak: Early adulthood is characterized as the period where most cognitive abilities are at or near their peak. During this time, adults demonstrate high proficiency in:
Learning new information quickly.
Solving problems with high efficiency.
Thinking abstractly.
Multitasking effectively.
Formal Operational Thought (Piaget): Adults continue to utilize the cognitive structures established in Piaget's final stage. This includes:
Abstract Thinking: Moving beyond concrete examples to conceptualize theoretical ideas.
Logic: Using systematic reasoning to reach conclusions.
Hypothetical Problem Solving: The ability to address complex scenarios. Example question: "What would happen if…?"
Planning Ahead: The capacity for long-term goal setting and anticipation of consequences.
Postformal Thought: This stage marks a significant departure from adolescent cognition. Key realizations include:
Complexity of Reality: Understanding that the world is multifaceted and nuanced.
Plurality of Truth: Recognizing that different viewpoints can each contain elements of truth.
Abandonment of Absolutes: Unlike teenagers, who may think in "black and white," adults shift toward an "It depends" mentality.
Dialectical Thought: A specific form of postformal thought defined by the ability to accept:
Contradictions.
Opposing ideas.
Multiple truths simultaneously.
Example: An adult stating, "I understand both sides."
Dichotomous Thinking: The polar opposite of dialectical thought. This involves viewing everything as binary:
Right or wrong.
Good or bad.
Success or failure.
There is no "gray area."
Memory Aid for Thinking Styles:
Dialectical = gray area.
Dichotomous = black and white.
Middle Adulthood Cognition and Expertise
The Intelligence-Memory Distinction: It is critical to note that while memory changes occur in middle adulthood, यह does not imply that intelligence disappears.
Fluid Intelligence: This refers to the innate ability to solve new problems, think quickly, and learn unfamiliar information.
Trajectory: This typically declines with age.
Examples: Solving puzzles, learning a new language, or tackling a brand-new math problem.
Memory Aid: Fluid = flexible thinking.
Crystallized Intelligence: This represents the accumulation of knowledge gained through experience.
Included Components: Vocabulary, factual knowledge, wisdom, and technical skills.
Trajectory: Usually remains stable or improves throughout middle adulthood.
Memory Aid: Crystal = stored knowledge.
Seattle Longitudinal Study: One of the most extensive studies regarding adult cognitive aging.
Primary Finding: Sudden cognitive decline is not the norm for most adults.
Patterns: Some abilities decline while others remain stable for decades. Declines often happen much later in life than commonly expected.
OA Scenario: An older adult may perform worse on tasks requiring speed but retain an excellent vocabulary; this is categorized as "normal aging."
Characteristics of Expertise: Experts process and apply knowledge differently than novices. There are four hallmark characteristics:
Intuitive: Quick pattern recognition.
Automatic: Requires less conscious effort to perform tasks.
Strategic: The ability to select the most effective methods for problem-solving.
Flexible: Adapting existing knowledge to fit new or novel situations.
Summary: Experts do not just possess more facts; they possess superior methods for utilizing that knowledge.
Cognitive Changes in Late Adulthood
Variability in Memory Decline: Not all memory types decline equally.
Working Memory: Functions as a temporary workspace for holding information during use (e.g., remembering a phone number long enough to dial it). Components include:
Central Executive: The "boss" that directs attention.
Phonological Loop: Stores sounds and words.
Visuospatial Sketchpad: Stores images, maps, and locations.
Long-Term Memory Types:
Episodic Memory: Memory of personal experiences (e.g., your wedding, yesterday's dinner, a vacation). This type often declines.
Semantic Memory: Memory for facts and meanings (e.g., the capital of France, word definitions). This type remains relatively stable.
Procedural Memory: Skills or "how-to" knowledge (e.g., riding a bike, typing, tying shoes). This is usually well preserved.
Prospective Memory: Remembering to perform a future action (e.g., taking medicine, attending an appointment). This becomes harder with age.
Implicit Memory: Unconscious memory and automatic behaviors. This usually remains strong.
Processing Speed: Identified as one of the earliest cognitive changes. Older adults typically require more time for tasks, which reflects slower processing rather than a loss of intelligence.
Inhibition Theory: This theory suggests that older adults struggle more with ignoring irrelevant information.
Example: Attempting to study while the television is on becomes significantly more difficult.
Wisdom: Distinct from general intelligence, wisdom includes experience, judgment, emotional understanding, and practical knowledge. Crucially, wisdom can continue to increase with age.
Neurocognitive Disorders and Brain Aging
Alzheimer’s Disease: The most common neurocognitive disorder, characterized by specific physiological brain changes:
Beta-amyloid Plaques: Protein build-ups that occur outside of the cells (between neurons).
Tau Tangles: Twisted proteins that form inside the neurons.
Hippocampus Impact: One of the first areas affected, leading to difficulty forming new memories.
Common Symptoms: Memory loss, confusion, getting lost, personality changes, and language difficulties.
Normal Brain Aging:
The brain becomes slightly smaller.
Processing and reaction times slow down.
Learning takes more time.
Note: Many older adults maintain high levels of intelligence despite these physical changes.
Plasticity: The brain retains the capability to change and learn throughout the lifespan.
Bilateralization: A compensatory mechanism where older adults use both hemispheres of the brain for tasks that younger adults complete using only one side.
Scaffolding Theory: This describes how the aging brain recruits additional neural circuits to maintain performance levels, essentially building "extra supports."
Cognitive Reserve: A protective factor built through education, reading, mentally stimulating activities, exercise, and social engagement. High reserve allows individuals to delay the onset of dementia symptoms.
Psychosocial Development in Middle Childhood (6–12)
Social Shifts: While parents remain important, peers, teachers, and school culture become increasingly influential.
Friendships: Become more stable and are increasingly based on trust, loyalty, and emotional support. Selection criteria shift from "playing together" to shared interests and personality traits.
Sociometric Status: How a child is viewed by classmates. Five categories:
Popular: Well-liked, friendly, cooperative.
Rejected: Actively disliked; often aggressive or withdrawn. Higher risk for loneliness and academic/behavioral problems.
Neglected: Rarely noticed; neither liked nor disliked. These children are usually shy or quiet.
Controversial: Liked by some and disliked by others; often outgoing leaders who may be aggressive.
Average: Liked by some and disliked by others, but not to the extremes of the other categories.
Bullying: Defined as repeated, intentional harm involving a power imbalance. Forms include:
Physical: Hitting, kicking, pushing.
Verbal: Teasing, insults, threats.
Relational (Social): Excluding individuals, spreading rumors, damaging friendships (hardest to recognize).
Cyberbullying: Occurs online and can happen at any time.
Parenting Styles and Family Dynamics
The Four Major Styles:
Authoritative: High Warmth / High Control. Parents set and explain rules. Outcomes: Confident, responsible, independent children (Best overall outcomes).
Authoritarian: Low Warmth / High Control. "My way or the highway." Outcomes: Obedient but anxious children with lower self-esteem.
Permissive: High Warmth / Low Control. Few rules. Outcomes: Children with poor self-control and impulsive behavior.
Uninvolved: Low Warmth / Low Control. Basic needs are met, but there is little emotional involvement. Associated with the poorest outcomes.
Divorce and Blended Families: Children's adjustment depends on the level of conflict and the quality of parenting post-divorce. Ongoing parental conflict is more harmful than the divorce itself. Blended families require time for children to adjust to new roles and routines.
LGBTQ+ Parents: Research consistently demonstrates that children of lesbian or gay parents develop just as well as those of heterosexual parents. Quality of parenting and stability are the true predictors of health, not sexual orientation.
Cultural and Emotional Influences
Individualistic vs. Collectivist Cultures:
Individualistic: Values independence and personal success (e.g., US, Canada). "Me" focus.
Collectivist: Values family, group harmony, and cooperation (e.g., many Asian, African, and Latin American cultures). "We" focus.
Self-Concept vs. Self-Esteem:
Self-Concept: The answer to "Who am I?" (e.g., "I am a big sister," "I am funny"). Descriptions become more psychological with age.
Self-Esteem: The answer to "How do I feel about myself?" (Confident/capable vs. self-doubt).
Self-Control Skills:
Response Initiation: Starting a required behavior (e.g., cleaning up when asked).
Response Inhibition: Stopping an inappropriate behavior (e.g., not yelling when angry).
Delayed Gratification: Waiting for a larger reward (The "Marshmallow Test").
Psychosocial Foundations: Birth Through Early Childhood
Erikson’s First Three Stages:
Trust vs. Mistrust (0–12 months): Can I trust the world? Based on caregiver consistency/responsiveness.
Autonomy vs. Shame & Doubt (1–3 years): Can I do things myself? Based on support for independence.
Initiative vs. Guilt (3–6 years): Can I take initiative? Based on encouragement of exploration/questions.
Attachment Styles (Ainsworth’s Strange Situation):
Secure: Explores, upset by departure, comforted by return.
Avoidant: Ignores caregiver, doesn't seek comfort.
Ambivalent (Resistant): Very clingy, distressed when caregiver leaves, resists comfort upon return.
Disorganized: Fearful, confused behavior; often linked to trauma.
Temperament: Inborn personality style (Easy, Difficult, Slow-to-warm-up).
Goodness of Fit: The match between a child's temperament and their environment/parenting.
Play Stages:
Solitary: Playing alone (infants/toddlers).
Parallel: Playing beside each other, but not together.
Associative: Playing together, sharing, but with no common goal.
Cooperative: Working together toward a single goal (common in preschool).
Cognitive Development: Middle Childhood through Adolescence
Piaget: Concrete Operational (7–11 years): Logical thinking about real (concrete) situations. Key skills:
Conservation: Quantity remains the same despite appearance changes.
Classification: Grouping objects by characteristics.
Seriation: Arranging items in order (e.g., shortest to tallest).
Reversibility: Understanding actions can be mentally reversed ( means ).
Information Processing: Improved working memory and metacognition ("thinking about thinking").
Piaget: Formal Operational (12–18 years): Abstract, hypothetical reasoning.
Hypothetical-Deductive Reasoning: Systematically testing possibilities.
Adolescent Egocentrism: Belief that thoughts/feelings are unique.
Imaginary Audience: Feeling that everyone is watching.
Personal Fable: Feelings of being special, misunderstood, or invincible.
Pseudostupidity: Thinking becomes so complex that the adolescent may fail to see simple solutions.
Socioemotional Aspects of Adulthood and End of Life
The Sandwich Generation: Adults simultaneously caring for their own children and their aging parents.
Kinkeeping: The act of keeping the family connected (organizing holidays, checking on relatives), often performed by women.
Empty Nest: Transition when children leave home; often leads to improved marital satisfaction rather than automatic depression.
Socioemotional Selectivity Theory: As time feels limited, older adults prioritize relationships and activities that provide the most emotional meaning.
Grief and Bereavement:
Bereavement: The factual state of having lost someone.
Grief: The internal emotional response.
Mourning: The external expression (funerals, cultural rituals).
Types: Anticipatory (before death), Complicated (prolonged/interfering), Disenfranchised (not recognized by society).
Dual Process Model: Cycling between Loss-Oriented (focusing on the grief) and Restoration-Oriented (learning to live life/paying bills/hobbies).
