- Aims o To introduce the major questions/themes that interest developmental psychologists o To illustrate common research designs that are used to answer questions about development
o What is developmental psychology? o Developmental psychologists seek to describe (what, when: rapid change in skills, how) and explain (why: that development and mechanism has occurred) the changes that occur across the life span. o Apply our knowledge. Developmental psychologists try to use their knowledge to optimize developmental outcomes.
• E.g. locomotor development:
• Locomotor development can impact on things like babies who are crawling are much better at generalizing …show more content…
o The Embryonic Period
• 3rd – 8th week
• blastocyst implants in the uterine wall
• Layers of cells differentiate to become
• Ectoderm (outer layer) o Nervous system, skin, hair
• Mesoderm (middle layer) o Muscles, bones, circulatory system
• Endoderm (inner layer) o Digestive system, lungs, urinary tract and other vital organs
• Placenta – a complex organ made up of tissue from both the mother and the embryo that acts simultaneously as a barrier that prevents the bloodstream of the mother and the embryo/foetus from coming into direct contact; and as a filter that allows nutrients, oxygen and waste products to be exchanged
• A period of rapid development
• All the basic organs are formed
• 4 weeks
• if there is neural tube damage → spina bifida o Foliate supplements = reduces risk, must be taken while trying to get pregnant.
• 6 weeks
• Brain is differentiated – 50% of foetus
• Facial features, gall bladder, liver, pancreas, finger
• Clef palate malformations occur here.
• 8 weeks
• end of embryotic …show more content…
mass toxin input) likely to miscarriage o The Fetal Period
• Last 7 months
• Period of rapid growth and refinement of organ systems
• Fetus is more responsive
• Behaviour becomes increasingly regular and integrated.
• Fetuses become viable (able to survive outside womb) between 22-28 weeks
• Organs are functional
• 12 weeks
• Sucking and breathing motions although lungs are not formed
• 13 weeks
• End of the first trimester
• Spinal cord recognizable and kidneys are able to secrete
• Sexes are externally visible
• 18 weeks
• Rest of the body catches up in growth size
• Baby like behaviour
• 24weeks
• Startled by loud noises
• It is though that what the mother eats influences the taste of the amniotic fluid – taste buds are formed. o This influences the preferences to food with children
• 6 months
• Fetus is capable of responding to light
• Able to hear sound o 75db in the uterus o Mothers voice and heartbeat are best heard
• 7 months
• Third
