Developmental Psychology Notes
Examines how people are continually developing- physically, cognitively, and socially – from infancy through old age.
Nature and Nurture: how do genetic inheritance and experience influence our development?
Should always be in the back of your head during this unit.
Are you who you are because of the way you were born or because of the way you were raised?
Continuity and stages: is development a gradual, continuous process like riding an escalator, or does it proceed through a sequence of separate stages, like climbing rungs on a ladder?
Stability and change: do our early personality traits persist through life, or do we become different persons as we age?
Prenatal Development and the Newborn
Prenatal Development
The process starts when a woman produces a mature egg.
Women are born with all the immature eggs they will ever have, while men develop sperm at puberty.
One sperm penetrates the protective layer of the egg and the nuclei fuse into one.
Fertilized eggs are called zygotes.
10 days after conception, the zygote attaches to the mother’s uterus, the zygote’s inner cells become the embryo, organs begin to form and function, and the heart starts beating.
By 9 weeks after conception, the embryo looks unmistakably human. It is now called a fetus. It is responsive to sound and will prefer its mother’s voice to another’s.
The placenta is a protective “sac” to nourish and keep the fetus safe.
Some substances can slip by, like teratogens, which are harmful agents like drugs or viruses. Whatever a pregnant mother does, many times their child will do the same. (drugs) If a mother smokes, the baby could be born with medical issues. Alcohol consumption leads to fetal alcohol syndrome.
First period is called menarche.
The Competent Newborn
When a baby is born, they are born with some innate tendencies.
Habituation: decreasing responsiveness with repeated stimulation.
The dog-cat test sowed that infants along with humans looked

    The egg which is the ripest is released and this process is known as ovulation. The fallopian tubes then suck up the egg, which then goes through the ovaries and ends up in the uterus. Every woman’s ovulation depends on their cycle’s duration. However, the average length of ovulation is typically between 12 to 14 days before the individuals’ next period. On average, an egg can live for almost 24 hours after it’s been released, however it would need to be fertilised by the sperm so that a baby is conceived. In addition, if the egg is fertilised by a healthy sperm when it’s on its way to the uterus, this is when the process of creating a new life…

    Although this collection of cells begin to organize rapidly into the brain, nervous system, circulatory system, muscles, and skeletal structure, the appearance for many weeks is grotesque, not even resembling human form. The point at which I think the life can be considered human is when brain signals can be detected and the fetus has taken on a human appearance. This occurs around 12 weeks. Until this point I do not consider abortion to be the taking of a human life. However after 3 months, abortion, is not justified unless there was a great danger to the mother's life. In fact, this is the point at which the embryo (a swelling) changes its name to be a fetus (meaning young one or…

    Developmental theories of child development are categorized as either stage theory or non-stage (continuous) theory. Both attempt to explain how each child is molded into the adult each will inevitably become. Stage theories propose that children make sudden shifts to different levels of behavior and perception. This way of thinking provides researchers with a set of guidelines as to how far children should be along in their development at different ages. It invokes a sense of “normality” and reassures people that their children are “on track.” It also serves as a way to identify if a child is behind where they should be in their development. Non-stage theorists propose that children’s’ development occurs more gradually. This idea of development…

    Psychology addresses various aspects of human development, such as biological, cognitive, and psychosocial. Biological development includes bodily changes, maturation, and growth. Mental processes of knowing, which includes imagining, perceiving, reasoning, and problem solving comes in cognitive development. Psychosocial holds the process of emotions, personality, and social interactions and expectations. These developments take place from birth through the life span. One of the stages of development as this paper will focus on is childhood (ages 3-12).…

    Abortion is the termination of a pregnancy through the death of the fetus. Some may argue that a fetus does not obtain “personhood” at conception because it is only a cluster of cells; it is an embryo, a zygote, and is not self aware. Therefore, the killing of a fetus is just. This argument is unsound in the fact that there are no set qualifications for personhood other than having human characteristics and feelings. A zygote is considered to be biologically alive; it fulfills all four of the criteria needed to earn the title: it has a metabolism, grows, reacts to a stimulus, and is able to reproduce. The heart begins to beat around 18 to 21 days after conception (Robinson 2010). At this point, the woman may only suspect that she is pregnant.The fetus continues to grow and become more like a person with each passing week. With a natural pregnancy, there is nothing to stop the fetus from developing further. So, the question then becomes when to consider the fetus a person? The fact that the fetus…

    Pregnancy begins when a sperm penetrates an egg. One to one and a half days later, the single fertilised egg cell begins to divide. After two or three days there are enough new cells to make the fertilised egg the size of a pin head. The embryo then gets attached to the wall of the uterus by a placenta. Then a chemical signal stops the woman from having another menstrual period. After eight weeks, the embryo may have grown to between 3 and 4 cm, has a recognisable heartbeat and the beginnings of the eyes, ears, a mouth, legs and arms. At this stage the growing organism is called a foetus.…

    Within just a few hours after conception, the singe-celled zygote begins making a journey down the fallopian tube to the uterus where it will begin the process of cell division and growth. The zygote first divides into two cells, then into four, eight, sixteen, and so on. Once the eight cell point has been reached, the cells begin to differentiate and take on certain characteristics that will determine the type of cells they will eventually become. As the cells multiply, they will also separate into two distinctive masses: the outer cells will eventually become the placenta while the inner cells will form the embryo.…
