    Sensorimotor Stage(0-2 years old)

    The stage in Piaget's theory during which infants know the world mostly in terms of their sensory impressions and motor activities.
  • Period: to

    Easy Temperament

    Adaptable to new situations; predictable in their rhythmaticity or schedule, positive in their mind.
  • Period: to

    Difficult Temperament

    Intense in their reactions; not very adaptable to new situations; slightly negative mood; irregular bodily rhythms.
  • Period: to

    Slow to Warm Up

    Initially withdraw when approached, but later may "warm up", slow to adapt to new situations.
  • Period: to

    Trust vs. Mistrust

    If needs are dependably met, infants develop a sense of basic trust. If the child is badly cared for, he/she will become insecure and mistrustful.
  • Period: to

    Preconventional Morality

    Before age 9, most children's morality focuses on self interest. They will obey the rules either to avoid punishment or to gain concrete rewards.
  • Period: to

    Secure Attachment

    A secure attachment is one where the child is sad when the parent or caregiver leaves, but when the parent or caregiver returns the child is happy again. These children feel protected by their caregiver and trust that they will return. This is very important because it can develop trust in early childhood which will have an effect on a person throughout their life.
  • Period: to

    Insecure attachment

    There are two types of insecure attachments. In an axious-ambivalent attachment, the child is upset when the caregiver leaves and angry when the caregiver returns. In an axious-avoident attachment, the child is not very concerned when the caregiver leaves and has little contact with the caregiver. These are both very important because they can affect a person throughout their lifetime.
  • Raise head to 45 degrees(2months)

    Two months after being born, the baby can raise his head to 45 degrees.
  • Baby rolls over(2.8 months)

  • Baby can sit with support(4 months)

  • Baby can sit without support(5.5 months)

  • Baby can pull itself to a standing position(7.6 months)

  • Baby can walk holding on to furniture(9.2 months)

  • Baby can creep(10 months)

  • Period: to

    Autonomy vs. shame and doubt

    Toddlers learn to exercise their will and do things for themselves, or they doubt their abilities. A "well parented" child emerges from this stage sure of self.
  • Period: to

    Preoperational Stage(2-6 years old)

    The stage in Piaget's Theory during which a child learns to use language but does not yet comprehend the mental operations of concrete logic.
  • Period: to

    Initiative vs. Guilt

    Children learn to initiate tasks and carry out plans, or they feel guilty about their efforts to be independent. A healthy child learns to imagine, cooperate with others, lead and follow. The negative child is fearful, hangs on to the outside of the group, continues to depend on adults, and is restricted in play skills as well as imagination.
  • Period: to

    Industry vs. Inferiority

    Children learn the pleasure of applying themselves to tasks, or they feel inferior. The child learns to relate with peers according to rules, progresses from free play to play that may be structured by elaborate rules, and masters social skills.
  • Period: to

    Concrete Operational Stage(7-11 years old)

    The stage in Piaget's Theory during which children gain the mental operations that enable them to think logically about concrete events.
  • First Menarche(girls)

    Usually occurs around 11 years of age.
  • Formal Operational Stage(begins at 12 years old)

    The stage in Piaget's Theory during which people begin to think logically about abstract concepts.
  • Conventional Morality

    By early adolescence, morality focuses on caring for others and on upholding laws and social rules, simply because they are the laws and rules. This stage usually occurs in the early adolescence period of children.
  • First Spermarche(boys)

    Usually occurs around age 13 for boys. Usually occurs while asleep.
  • Period: to

    Identity vs. Role Confussion

    Teenagers work at refining a sense of self by testing roles and then integrating them to form a single identity, or they become confused about who they are and what they are meant to do or be.
  • Physical Changes During Puberty

    During puberty, females will develop breasts and hips as well as pubic and underarm hair. Males will get facial hair and their voices will deepen. They will also develop pubic and underarm hair.
  • Postconventional Morality

    With the abstract reasoning of formal operational thought, people may reach a third moral level. Not all people reach this level of morality. Actions are judged "right" because they flow from people's rights or from self-defined, basic ethical principles.
  • Period: to

    Intimacy vs. Isolation

    Young adults struggle to form close relationships and to gain the capacity for intimate love, or they feel socially isolated. A young adult can, for the first time, experience true intimacy or love that makes good marriage or friendship possible.
  • Period: to

    Changes in Sensory Abilities

    Sight, smell, and hearing all decline in mid and late adulthood. In later life, visual sharpness diminishes, and distance perception and adaptation to changes in light level are less acute. With age, the eye's pupil actually shrinks and its lens becomes less transparent, reducing the amount of light reaching the retina to about 1/3 that of a 20 year old. Your memory also weakens as you are more likely to remember meaningful information. Fluid intelligence also decreases in late adulthood.
  • Period: to

    Generativity vs. Stagnation

    In middle age, people discover a sense of contributing to the world, usually through family and work, or they may feel a lack of purpose.
  • Period: to

    Physical Changes in Middle and Late Adulthod

    During middle and late adulthood, muscular stregnth, reaction time, sensory keenness, and cardiac output are all physical changes that occur. These adults will also start to develop wrinkles
  • Menopause

    Menopause is the time of natural cessation of mentruation. It also refers to the biological changes a women experiences as her ability to reproduce declines. This usually occurs within a few years of age 50.
  • Intgrity vs. Despair(late 60's and up)

    A person will reflect on his or her life, an older adult may feel a sense of satisfaction or failure, depending on how they look back at their life.
