Psychological development is both nature and nurture Human thought and behavior is heavily influence by genetically controlled processes of development. This innate aspect of development is called maturation. Environmental factors can help or harm this process. Socio-cultural environment teaches children the rules they need to follow and behaviors that are appropriate in different situations. This learned aspect of development is called socialization but an individual’s genes may support of interfere with this process. From conception to birth /The Germinal phase (0-2 weeks) The outer part of the blastocyst forms part of the placenta and umbilical cord, which allows the mother to provide nutrients and remove waste. The inner part becomes the embryo. The Embryonic Stage (2 weeks-8 weeks after conception) / This begins with the implantation into the wall of the uterus. Secretion of testosterone between weeks 4-8 causes development into a male, otherwise a female results. / The fetal stage (8-38 weeks) Development initiated in the embryonic stage continues until birth. Most brain development occurs during last 12 weeks of pregnancy. The effects of nurture on nature Mother’s placental barrier functions to block many threats to embryonic development…but not all… Some of these threats include German Measles (or rubella), exposure to radiation and toxic chemicals (lead), sexually transmitted diseases, cigarette smoking, heavy alcohol use (fetal alcohol syndrome), and other drugs (heroin, cocaine...) The newborn An effect of nature on nurture Learning about the environment is aided in infants by innate motor reflexes. They include grasping objects placed in their hands, rooting or turning in response to a touch on the cheek or mouth in an effort to search for their food source. Learning about the environment is also aided in infants by innate sensory abilities. First, infants becomes experts at knowing what sensory information means (mom and dad versus everyone else) and then they can learn rapidly by witnessing events and witnessing the consequences of their own behavior. Newborns are present to be socially interactive. They prefer faces to other sensory information, they smile for no reason and caregivers love that and they produce nonsensical sounds that caregiver’s love and will respond with them to caregiver’s speech. A challenge faced: attachment Attachment provides an infant with a source of biological need for nourishment and protections and a safe base to explore and learn about the world. Their innate need for attachment in infants revealed by research on behavior in animals to achieve contact comfort and emotional consequences of not receiving it.

Harlow and Harlow (1966) They raised infant rhesus monkeys with one of the two artificial mothers. The wire mother was a little scary and not very nice to touch and the cloth mother was more soothing and soft to the touch. Their question was “do infants form attachments just for food?”

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
