Santrock Life-Span Development: A Topical Approach
Life-Span Development: A Topical Approach
John W. Santrock

Biological Process, Physical Development, and Health
Biological Beginnings

Learning Objectives

1.

Discuss Darwin's concept of natural selection and its relationship to adaptive behavior.

2.

Evaluate evolutionary psychology's emphasis on the importance of adaptation, reproduction, and "survival of the fittest" with respect to explaining behavior and explore:
  • Baltes' view of the benefits of evolutionary selection
  • how cultural needs increase with age
  • Bandura's argument for a bidirectional view of evolutionary and environmental influences

3.

Understand the genetic foundations of life, including:
  • the structure and function of chromosomes, DNA, and genes
  • the distinction between mitosis and meiosis
  • genetic principles (such as dominant-recessive), behavior genetics, molecular genetics, and chromosome and gene-linked abnormalities

4.

Explain heredity-environment interaction, including passive, evocative, and active genotype-environment correlations and the ways in which genetic loading establishes a propensity for behavior to develop according to particular developmental trajectories.

5.

Describe the germinal, embryonic, and fetal periods of development, as well as the method and purpose for the prenatal tests: amniocentesis, ultrasound sonography, chorionic villus sampling, and the maternal blood test.

6.

Address teratology, hazards, and protective factors that may affect the unborn child during prenatal development, including:
  • prescription and nonprescription drugs
  • psychoactive drugs
  • environmental hazards
  • maternal factors
  • paternal factors
  • avoiding vulnerabilities

7.

Describe the three stages of birth, the various childbirth strategies and methods of delivery, and the commonly used measures of neonatal health and responsiveness; distinguish between preterm infants and low-birthweight infants; and comment on whether bonding is critical for the competent development of infants and the well-being of their mothers.
