Timeline of Psychology Throughout the Lifetime

  • Prenatal Development & Birth

    -Sperm meets ovum; I exist!
    -In the first 14 days, I developed into a blastocyst.
    -During the 3rd to 8th week after conception, I grew into an embryo.
    -From the 9th week on, I was called a fetus, until the day I was born, 7/11/91.
  • First Two Years: Biosocial

    Biosocial: By age 2, I grew to almost half of my adult size and developed regular sleep patterns. Also by age 2, my brain grew to almost three-fourths of its adult weight, dendrites and synapses expand and develop, and dendrites that aren't being used anymore began to shrink. Personal experiences taught me many things. My senses sharpened rapidly and by the time I was one year old, it was evident. I could hear, see, smell, taste and touch and used this to take in the world around me.
  • First Two Years: Cognitive

    I learned many things through Piaget;s Six Stages of Sensorimotor Intelligence. I adapted through assimilation and accommodation, learning things like object permanence, pursuit of goals, and deferred imitation. At one year old I was beginning to speak simple words and phrases, by two, I could speak in holophrases, and two word sentences.
  • First Two Years: Psychosocial

    After I was born, I could only express feelings like distress and contentment by crying or looking happy. Eventually, I started laughing and smiling socially. After about 6 months, I was able to express things like anger and fear. From 12 to 24 months, my emotions became more obvious and complex, displaying things such as pride, shame, and embarrassment. My parents loving and nurturing behaviors helped shape a positive temperament and secure attachment.
  • Play Years: Biosocial

    I grew stronger, taller, and thinner throughout my play years, influenced by a healthy diet and an active lifestyle. My brain developed via myelination which sped up my reaction time to varying stimuli, allowed me to begin thinking before acting, more careful motor skills, and learn better ways to express my emotions. My parents and different laws helped to keep me safe at such a vulnerable age.
  • Play Years: Cognitive

    According to Piaget, I was unable to perform logical operations. My parents used language to guide my actions. My language skills expanded from 100 words to many thousands. A high-quality daycare helped me to improve social and language skills.
  • Play Years: Psychosocial

    I developed a self concept based on components such as pride, purpose, and inititive and learned to regulate my emotions. My parents raised me in an authoritative way, they were proud of my accomplishments but didn't leave bad behavior unaddressed. I acquired a girly sense of self, following cues from gender stereotypes.
  • School Years: Biosocial

    I continued to grow big and strong and stayed healthy with the aid of immunizations. Although I didn't have either of these problems, some classmates missed school because of “embarrassing” things such as obesity or asthma. I was able to focus on things more easily because of neurological maturation. Achievement tests measured to make sure I was where I was supposed to be developmentally, and monitored for disabilities such as Autism, attention-deficit, Dyslexia, and Asperger's.
  • School Years Cognitive

    During my school years, I learned new things, and built knowledge from what I already learned. My working memory increased in speed and capacity. I could distinguish when speech needed to be formal, and when it was okay to be informal. My school did a great job at teaching me the basics that I used as a foundation for the rest of my educational ventures.
  • School Years: Psychosocial

    Morally, I started to decide how I was going to live my life, personal values, thinking for myself on a whole new level.My nuclear family provided basic necessities like friendship, harmony, and stability. The school years were the point at which I started becoming a responsible, maturing person with a more realistic self-concept.
  • Adolescence: Biosocial

    During my adolescent years, I went through puberty. I grew bigger and taller. hormone levels increased, and I developed primary and secondary sexual characteristics. Brain growth and hormones contributed to an increased curiosity in sexual activities. I also got into drugs at this point in my life.
  • Adolescence: Cognitive

    My thinking was more developed than childrens at this point, and I was able to use abstract logic, a part of formal operational thought. Egocentrism was a battle, it made me think everyone noticed what I did, and wore, and how I acted. Intuition also increased at this time. I was learning more and more as the pressure to succeed increased.
  • Adolescence: Psychosocial

    I began looking for and refining my very own identity, this was a combination of experiences from throughout my life. Deciding things about religion, sex, vocation, and politics/ethnicity. I began having romantic relationships. Depression was also something that I struggled with throughout middle school and the beginning of high school.
  • Emerging Adulthood: Biosocial

    Developing a strong, healthy and active body. I began routinely working out and eating healthier foods. Risk taking was a temptation and drinking could potentially become a problem.
  • Emerging Adulthood: Cognitive

    i reached the fifth stage of cognitive development: combination of rational thought with emotional intuition. I went through some struggles in determining my religious self, after some rough experiences and contact with others beliefs. I also began attending college.
  • Emerging Adulthood: Psychosocial

    I picked which job I wanted to pursue but the rest of the details surrounding that continued to be a mystery. I had a couple long term relationships in hopes of finding a suitable partner to marry. I thought highly of myself, with confidence. Others my age were battling with emerging psychological disorders such as depression, anxiety and schizophrenia.
  • Adulthood: Biosocial

    Signs of aging began appearing, such as graying hair, wrinkles, loss of muscle tone, and changes in body shape. These changes can be distressing. Loss of hearing and sight started occuring and reduced levels of hormoes led to a decreased sex drive. Healthy habits continue throughout adulthood, usually avoiding tobacco, excessive drinking, and maintaining a daily exercise regimen.
  • Adulthood: Cognitive

    Intelligence and intellectual abilities fluctuate throughout adulthood, some increase and some decrease. To make up for losing some cognitive abilities, most adults tend to specialize in other more specific areas.
  • Adulthood: Psychosocial

    Chronological age matters less and less. Adults develop in way that reflect their big 5 personality traits and niches rather than "acting their age". Adults enjoy their intimate relationships with spouses, children, siblings, and parents, but half of marriages end in divorce, increasing stress among adults. Adults take on the role of caregivers, financially and socially for children and parents who need it.
  • Late Adulthood: Biosocial

    Ageism leads others around me to believe that I need more assistance with daily activities than I really do. Retirement allowed me to follow my lifelong dreams of traveling the world and sleeping in until whenever I want. Many of my friends are at the same place in life and we enjoy doing activities together. Although I maintain an active lifestyle, my brain slows, and my senses are dampened, hearing and vision loss begin setting in. Primary and secondary aging increase the risk of developin
  • Late Adulthood: Psychosocial

    While many people, after retirement, prefer to age in place, fix up homes and gardens, I drop everything and travel with my loved ones while I'm still able. I fill the rest of my time by returning to school for continuing education, volunteering, and involvement in political ventures. I maintain strong and healthy relationships with my family and friends, finding my greatest strength in others around my age. I face the risk of becoming what is known as “frail elderly,” and may begin needing as
  • Epilogue: Death

    I predict that if I live a relatively healthy life, I will pass away around 2078, at the age of 87. I hope to be surrounded by those I love, and by then I plan on coming to terms with death, and will be ready to pass on without fret and worry, no sadness, just a hope for what is to come.
  • Late Adulthood: Cognitive

    Wear and tear on the myelin sheaths of brain neurons begins to slow my brain down , as well as a decreased amount of neurotransmitters, and increasingly restricted blood flow in and out of the brain. I begin to struggle with short-term memory, but find new ways to cope. Memory loss may be an early symptom of Alzheimer's disease, strokes, Parkinson's, depression, or side effects of certain drugs. I begin to reassess and give more value to philosophical beliefs through a process called life revie
