psychology 10 Flashcards
What is developmental psychology?
studies age-related changes in the human development from conception to death
The were several theoretical issue guiding research in human development psychology. What are they?
- Nature (biology) vs Nurture (learning)
- Continuity vs stages
- Stability (maintained) vs change
What is Nature (biology) in Nature (biology) vs Nurture (learning)?
Nature– born with a particular genetic predisposition (e.g capacity to memorize al- Quran / play a musical) or the influence of our inherited characteristics on our personality, physical growth and intellectual growth.
What is nurture in Nature vs Nurture?
the influence of the environment on personality, physical growth, intellectual growth, and social interactions. eg: memorizing al –Quran / ability play music depend greatly to environment).
What is stages (discontinuity) in continuity vs stages?
behavior is qualitatively different at each stage of development (the behavior occur in a fixed sequence).
What is continuity in continuity vs stages?
continuous development with new abilities, skill and knowledge. (eg : adult thinking differ from child). Added according to age.
What is stability in stability (maintained) vs change?
personality characteristic stable from young to older age.
What is change in stability (maintained) vs change
personality characteristic during childhood not similar when grow older
Name 3 research methods
- Cross-sectional studies
- Longitudinal studies
- Cross-sequential design
studies several groups of individuals who are different ages at one time. What is the study?
cross-sectional studies
Use subjects who are all the same age and who are studied over a long period of time. What study is this called?
Longitudinal studies
research design in which participants are first studied by means of a cross-sectional design but also followed and assessed for a period of no more than six years. What study is this?
cross sequential design
give 4 advantages of cross sectional?
- Gives information about age differences
- Quick
- Less expensive
- Typically larger sample
What is a disadvantage to cross sectional?
restricted generalizability
The average human gestational period is 38-40 weeks. Because of the different changes that occur during these 40 weeks, developmental researchers divide this time frame into three phases. What are they?
i) Germinal stage (from conception to 2 weeks).* The earliest stage of gestation
ii) Embryonic stage (3 to 8 weeks) Early stage of development*
iii) The fetal stage (3 month – birth) Latter stage of prenatal development
On a child, Low birth weight, malformations, less developed brain, greater vulnerability to disease is caused by?
Malnutrition
Is characterized by the formation of the major organs and system, including the respiratory, excretory, cardiovascular, and nervous systems. Consequently, this stage of prenatal development is very precarious. Genetic abnormalities usually appear at this time.
embryonic stage
First two weeks after fertilization, during which the zygote moves down to the uterus and begins to implant in the lining embryo name for the developing organism from two weeks to eight weeks after fertilization. What stage is this?
Germinal stage
Categories of teratogens include:
– Legal and illegal drugs( alcohol, nicotine) ( damage in prenatal development, low IQ)
– Diseases and malnutrition
– Exposure to X-rays and stress exposure
The organism in this stage is referred to as a fetus. Although the fetus major features are basically complete by 12 weeks, the fetus continues to grow, differentiate and develop until birth.
fetal stage
What are hazards to development?
Teratogens (environmental agents that cause damage during prenatal development by crossing the placenta barrier)
On a child, Low birth weight, hyperactivity, irritability, feeding difficulties is caused by?
Stress exposure
On a child, malformations and cancer are caused by?
Exposure to xrays
On a child, inhibition of bone growth, hearing loss, low birth weight, fetal alcohol syndrome, mental retardation, attention deficits in childhood, and death are caused by?
legal and illegal drugs
