Lifetime human development milestones

  1. 1. V.M.WESTERBERG’S SUPER BRIEF THEORY SERIES LIFETIME DEVELOPMENTAL MILESTONES Infancy and Toddlerhood: Birth - Age 2 Biological • Body doubles in height and quadruples in weight • Neurons grow in increasingly dense connections, becoming coated with layers of myelin, and enabling faster and more efficient message transmission • Experiences help to fine tune the brain's responses to stimulation • Motor skills progress from simple reflexes to coordinated motor abilities, such as grasping and walking • Sensory and perceptual abilities develop rapidly Cognitive • Basic structure of language learned through baby talk with adults • First communication emerges through crying, then cooing and babbling • Language skills progress from speaking a few words by age 1, to constructing sentences by age 2 • Awareness of world progresses through immediate sensorimotor experiences to mental representations of events • Thinking includes concept of object permanence: objects still exist when out of sight or awareness • Ability to grasp conceptual categories begins; by age 2 numerous definite concepts develop Piaget’s sensorimotor stage Psychosocial • Emotional responses change from basic reactions to more complex, self-conscious responses • Independent behaviors increase with parental encouragement around feeding, dressing, and toilet training • Parents and infants respond to each other by synchronizing their behavior • Development of secure attachment sets stage for child's increasingly independent exploration • Ability to relate to playmates emerges by end of period • Early personality traits, such as introversion and extroversion, develop Erikson’s trust vs mistrust, autonomy vs doubt.
  2. 2. Early Childhood: Ages 2 - 6 Biological • Brain is 90% of its adult weight by age 5, developing faster than any other body part • Myelination proceeds at different rates in various areas of the brain, resulting in different rates of readiness for certain types of activities • Physical strength increases and body proportions become more adult-like • Athletic skills, such as running, jumping, and hopping, dramatically improve • Fine motors skills, such as writing and drawing, develop slowly • Gender differences in motor skills begin to emerge Cognitive • Use of mental representations and symbols, such as words, begins • Ideas about the world continue to be somewhat illogical • Social interactions with parents and playmates teach about the world • Language abilities develop rapidly, resulting, on average, in a 14,000-word vocabulary and extensive grammatical knowledge by age 6 • Ability to adjust communication to audience begins • Metacognition, the ability to think about thought, forms Piaget’s pre-operational stage (2-7) Psychosocial • Play alone or with others becomes increasingly complex and imaginative • Increased energy fosters ability to initiate new activities, especially if child receives praise for actions • First awareness of gender roles emerge • Desire for independence and control over environment increases, making parents' supervisory role more challenging • Parenting style influences child's psychosocial development • Socialization in school encourages thinking about world outside the home Erikson’s autonomy vs doubt (1-3), Initiative vs guilt (3-6)
  3. 3. Middle Childhood: Ages 7 - 9 Biological • Brain growth slows down • Physical growth slows, but slight height spurts occur • Expansion of heart and lung capacities supports more physical endurance • Athletic and fine motor skills become more refined Cognitive • Ability to understand logical principle develops • Memory capacity and ability to use mnemonics expands • Metacognition, the ability to think about thought, enables organization of own learning • Use of language becomes more analytical • Proficiency in more than one language code may begin, sometimes resulting in bilingualism Piaget’s preoperational stage Psychosocial • Peer group becomes more significant as dependence shifts to friends for help, loyalty, and sharing of mutual interests • Awareness of and involvement in outside world increases awareness of family, economic, and political conditions • Motivational systems build around achievement, competence, and affiliation • Coping strategies develop for problem solving and stress tolerance • Interpersonal strategies develop to aid in understanding others' behaviour Erikson’s Initiative vs Guilt (3-6) Industry vs Inferiority (6-12)
  4. 4. Late Childhood: Ages 10 - 12 Biological • Puberty begins with rising hormone levels • Girls' growth spurt begins with gains in height, weight, and musculature • Gender specific physical changes appear within first year: enlargement of breasts in girls and testes in boys • In physical maturation, boys lag, on average, 2 years behind girls • Variations in onset of puberty impact personality development Cognitive • Logical thought progresses to abstract thinking • Planning skills and memory strategies improve • Long-term knowledge base grows • Language skills expand to include synonyms, categories, double meanings, metaphors, humor, and complex grammatical structure Piaget’s concrete operational stage Psychosocial • Changes in physique, sexuality, cognitive functioning, and society's treatment may challenge sense of self • Appreciation of connection between moral rules and social conventions strengthens • Peer groups often divide into cliques • Awareness of gender stereotypes continues to increase • Issues increase around autonomy, sibling rivalry, and separation from family Erikson’s Industry vs Inferiority (6-12)
  5. 5. Early Adolescence: Ages 13 - 15 Biological • Body continues to grow in height and weight • Girls growth spurt peaks, while boys typically begin it • Motor performance gradually increases, but often levels off for girls • Girls usually start to menstruate and boys to ejaculate Cognitive • Formal operational reasoning, the capacity for abstract, scientific thought, emerges • Thinking becomes more self-conscious, idealistic, and critical • Metacognition and self-regulation further develop • Vocabulary expands to include abstract words • Understanding and grasp of complex grammar continues to improve • Ability to grasp irony and sarcasm develops Piaget’s formal operational stage Psychosocial • Issues of identity emerge, potentially leading to crisis in sense of self • Sexual orientation begins to emerge • Psychological disorders and sociocultural- adaptational disorders may emerge • Strives for autonomy in relation to family continues to increase, and parent-child conflicts more likely to occur • Friendships have greater emphasis on intimacy and loyalty • Conformity to peer pressure increases Erikson’s Identity vs (role) Confusion (12-19)
  6. 6. Late Adolescence: Ages 16 - 19 Biological • Boys' growth spurt peaks, and growth is mostly complete by end of this period • Boys develop deeper voices and patterns of facial hair, and typically grow taller than their female peers • Girls tend to grow wider in the hips, and breast development continues for several years • Girls' motor performance peaks, while boys' continues to improve Cognitive • Reasoning through problems in symbolic terms and through use of formal logic improves • Fluid intelligence, the ability to cope with new problems and situations, is reached by the end of this period • Ability to understand and integrate rules into sense of self becomes basis for character development Piaget’s formal operational stage Psychosocial • Development of identity continues in relation to adult world • First dating begins process of developing and maintaining intimate relationships • Cliques decline in importance • Identity achievement greatly influenced by personal factors, including family and peer relationships with family and peers, and economic and political circumstances • Increased assertiveness and lack of self-discipline often create conflicts with parents • Sexual orientation continues to develop • Introduction begins to the world of work and career planning Erikson’s Identity vs (role) Confusion (12-19)
  7. 7. Early Adulthood: Ages 20 - 40 Biological • Physical functioning increases through the 20's and peaks at about age 30, but can be maintained through exercise • Body shape changes, with gradual increases in weight and body fat and decreases in lean muscle mass • Efficiency of many organ systems begins to diminish at the rate of about 1% a year • Sexual responsiveness remains high throughout this period, with some slowing in men • Physical appearance changes; gray hair and wrinkles develop toward end of this period Cognitive • Thinking may become practical and dialectical to adapt to the inconsistencies and complexities in daily experiences • Short-term memory peaks • Wisdom and expertise begin to develop • Vocabulary and knowledge continue to grow through work interactions and everyday problem- solving Piaget’s formal operational stage Neo-Piagetian postformal stage Psychosocial • Issues of identity and intimacy peak by age 30 • Need for affiliation filled by friends and often a marriage/partner • Friendships become particularly important for people who are single • Need for achievement often met through satisfactory work consistent with personality and abilities • Personality traits most likely to change up to age 30, with additional maturation continuing into the 40's Erikson’s Intimacy vs Isolation (20-45)
  8. 8. Middle Adulthood: Ages 40 - 65 Biological • Gradual changes continue in appearance of skin, hair, and body shape • Gradual changes occur in hearing and vision, including presbyopia, the inability to focus on near objects • Menopause begins in women • Health and potential onset of disease affected by preventive behaviors, many of which vary by social class Cognitive • Fluid intelligence declines while crystallized intelligence remains steady or increases • Intellectual abilities dependent on speed and novelty decrease, while abilities involving knowledge about the world and vocabulary increase • Reaction time and mental processing speed slow • Short and long-term memory remain relatively stable • Cognitive abilities related to experience and intelligence flourish, leading to further formation of expertise • Maintenance of cognitive skills as well as opportunities for intellectual growth impacted by social class Piaget’s formal operational stage Neo-piagetian postformal stage Psychosocial • Mid-life crisis occurs in a small minority of cases, because most men and women experience gradual transitions in sense of self and in relationship with the world • Personality traits tend to remain stable • Friendship and marriage/partnership continue as primary sources of affiliation • Marital satisfaction often rises as children move away from home • Maintenance phase in career may allow for greatest productivity at work, may also cause burn-out • Experiences of facing age discrimination more likely Erikson’s generativity vs stagnation
  9. 9. Late Adulthood: Ages 65 - Onward Biological • Brain becomes physically smaller and functions more slowly • Gradual changes continue in appearance, along with weakening of the body sense organs and major body systems • Losses continue in visual and hearing abilities • Decreases in immune system and overall muscle strength put older adults at risk of chronic and acute illness • Short-term memory may decline, but active exercise of mental abilities helps to maintain functioning • Age-related changes impact sexual functioning, but not pleasure Cognitive • Abilities to receive information, store it in memory, and organize and interpret it decline • Some short-term memory abilities declined, but methods can help compensate for memory loss and slower thinking • Aesthetic, philosophical, or spiritual interests emerge or intensify • Language abilities based on memory and processing speed decline, but overall vocabulary continues to grow • Driving-related abilities dependent on information- processing speed decrease, while skills based on experience increase • Wisdom, experience-based problem solving, and semantic knowledge increase. Older adults cognitive theories (Levinson, Neugarten) Psychosocial • Retirement experience shaped by social class and gender factors, including income, health, and amount of previous planning • Abilities to cope with stress, reduce negative emotions, and manage personal relationships improve broader perspective on life • Subjective sense of well-being tends to be higher than at all previous periods • Satisfaction with life largely dependent on family involvement • Bereavement for spouse, friends, and families stressful, but most people are able to integrate a loss into their lives within one year after it happens
