Define Development
The orderly and sequential changes occurring from conception until death.
What are the 3 patterns of growth?
Physical, Cognitive + Social
What are 4 traits of development?
- Lifelong 2. Multidimensional 3. Multidirectional 4. Culturally Influenced
What 2 things does development involve?
- Influences of cultural shifts 2. Changing resource allocations
What does development show?
Plasticity
Which lifespan is from 7-11 years
Middle childhood
Which lifespan is ages 3-6 years?
Early Childhood
When is the infancy lifespan?
From birth-age 2
What is the lifespan before birth?
Prenatal
What are the steps of designing an experimental methodology?
- form a hypothesis 2. choose # of participants and if experiment will be longitudinal, cross sectional, or both. 3. determine independant and dependant variable 4. determine experimental and control group
What is a longitudinal experiment?
data is collected from a group of similar individuals (cohort) over over time
What is a cross-sectional experiment?
data is collected one time from a group of different individuals (cohort) at once
What is a cross sequential experiment?
data is collected over time (years) from different groups of individuals (as categorized by a cohort)
What is a case study?
The experimenter intensively observes, describes, and documents observations of a participant(s)/subject(s).
What is a naturalistic observation?
The experimenter passively, usually discretely, observes the subject so as not to disturb them.
What is a self report?
The experimenter administers surveys, questionnaires or interviews participants.
What is descriptive scientific research?
Experimental methodologies that observation in an objective, and systematic manner.
What are the 3 limitations of descriptive research?
- Confounding variables: extraneous part(s) of the experiment that may affect the outcome. 2. Reactivity: The participant may (often unknowingly knowingly) alter their behavior due to an awareness that they are being observed. 3. Experimenter expectancy effect: The experimenter (often unknowingly) alters the experimental methodology to fulfill their expectations.
What are the 4 goals of ETHICAL research?
- Ensure more benefit than risk 2. Informed consent 3. Use of deception: volunteers have a right to know what will happen to them; if justified, humane deception can be used, and experimenter(s) should debrief the participants after experimental participation 4. Vulnerable pop. should be treated with special care
How many chromosomes are there in each biological cell?
23
What is a centromere?
The region of a chromosome that separates the chromosomes into arms
What is a gene?
A sequences of nucleotide bases in a chromosome that make specific proteins which perform specific functions associated with the human body
What is the germinal stage?
conception and fertilization, week 0-2 sperm penetrates egg > becomes a zygote > 12 hours later, zygote begins to duplicate > becomes blastocyst> day 11, implants into the uterus> day 14 becomes gastrula
When is the embryonic stage?
End of week 2-8
