Put these prenatal periods in the correct order:

Fetal — Germinal — Embryonic


Germinal → Embryonic → Fetal

Development involves changes in the body and brain, thinking and language, and emotions and relationships.
What life-span characteristic does this illustrate?


Multidimensionality

What newborn assessment is typically given at about 1 and 5 minutes after birth?

Apgar Scale

I produce new neurons during prenatal brain development.
What process am I?


Neurogenesis

One fertilized egg splits and develops into two individuals.

What type of twins result?

Baby A is born at 35 weeks but has an appropriate weight for that gestational age.

Baby B is born full term but weighs substantially less than expected for that gestational age.

Classify each baby.


Baby A → Preterm
Baby B → Small for gestational age

Two pregnancies involve exposure to the same potential teratogen, but the developmental outcomes are different.

Name TWO factors that could explain the difference.

  • Dose
  • Timing
  • Genetic/individual susceptibility


300

A child is naturally very outgoing. Her sociability causes adults and peers to interact with her more often.

Which genotype–environment correlation does this BEST illustrate?


Evocative genotype–environment correlation

A researcher finds that adolescents who spend more time on social media report more anxiety.

Can the researcher conclude that social media causes anxiety? Why or why not?


No. This is a correlation; correlation does not establish causation.

A premature infant is placed upright against a parent's bare chest for extended skin-to-skin contact.

Name this intervention AND explain its basic developmental purpose.


Kangaroo care

A potentially harmful exposure occurs while the major organs are beginning to form.

Identify:

1. The prenatal period
2. The developmental process occurring



  1. Embryonic period
  2. Organogenesis

Two children have a genetic tendency toward tall height.

One receives adequate nutrition throughout childhood; the other experiences severe nutritional deprivation.

They reach very different adult heights.

What major developmental principle does this case demonstrate?


Genes and environment interact in shaping phenotype/development.

A researcher wants to determine whether a new learning strategy actually causes better memory performance.

What type of research design would provide the strongest test of causation


Experimental design / experiment
