Lifespan Development Exam #21 Fully Solved
Life-span development - correct answer study of development across conception to
death
8 Stages of Development in order - correct answer Conception, Infancy, Early
childhood, Mid-childhood, adolescence, young adulthood, middle adulthood, later
adulthood
Conception (time course) - correct answer Prenatal. Before birth occurs
Infancy (time course) - correct answer Age 0-2
Early Childhood (time course) - correct answer Ages 2-6
Mid-Childhood (time course) - correct answer Ages 6-11
Adolescence (time course) - correct answer Ages 11-20
Young adulthood (time course) - correct answer Ages 20-40
Middle Adulthood (time course) - correct answer Ages 40-65
Later Adulthood (time course) - correct answer Ages 65+
3 Categories of Development - correct answer Physical - body development, physical
nature, biological processes
Cognitive - thinking development/ intelligence, and language
Socioemotional - interactions with other people, emotional changes/ personalit
Case study - correct answer An intensive study of one or a small number of individuals
or families.
In depth look at a single individual. Performed by mental health professionals, when for
either practical or ethical reasons.Provides info. About one persons' experiences
Correlation Study - correct answer A study in which the researcher examines two or
more variables to see if they are linked in any way.
Provides info that helps to predict how people will behave. Shows comparisons.
Describe the strength of the relation between two or more events or characteristics
Experimental research - correct answer study causality, carefully regulated procedure
where one or more factors believed to influence the behavior being studied are
manipulated while all other factors are held constant. This is a sure way of verifying a
study.
, Nature vs Nurture - correct answer Concerns the extent to which development is
influenced by nature and nurture. Nature refers to an organism's biological inheritance
and biological development/body;
Nurture refers to its environmental experiences.
Twin Study - correct answer The behavioral similarities between identical twins
(genetically identical) is compared with the behavioral similarities between fraternal
twins. If twins seprated, they will both have same nature aspects.
A method for estimating heritability in which the degree of similarity in a trait that is
observed among identical twins is compared with that observed among fraternal twins.
Adoption Studies - correct answer A method for estimating heritability in which
similarities between children and their adoptive parents are compared with similarities
between children and their biological parents.
Genotype - correct answer Genetic material makeup. Hh or HH or gggg or gggg
homozygous, heterozygous
Phenotype - correct answer Observable physical characteristics (weight, height, eye
color, hair color)
Mitosis - correct answer Cell body division replication of 22 autosomes (non-sex
chromosomal) Diploid cells (2n)
The process through which all cells other than gametes reproduce, in which a cell
divides and each resulting cell receives a full copy of all 46 chromosomes.
Meiosis - correct answer Cell division of gametes, sex cells egg and sperm, producing
23 unpaired chromosomes. Haploid cells (n)
The process through which gametes (sperm and ova) are produced, in which each
resulting gamete has half of the genetic material of the parent cell.
Dominant genes - correct answer one gene of a pair always exerts its effects; overrides
the potential influence of the other gene.
Recessive genes - correct answer exerts its influence only if two genes of a pair are
both recessive. If inherit a recessive gene for a trait from BOTH parents, the trait will be
shown.
Gestation - correct answer Time frame of Conception to Birth. Lasts 280 days from
mom's last period.
Fertilization - correct answer Fusion of sperm 23 chromosomes (n) with egg 23
chrosomes (n) to make a Zygote
Zygote - correct answer Fertilized egg by one sperm penetrating into the egg.
Life-span development - correct answer study of development across conception to
death
