Study Notes
Theme 1: Biological Versus Environmental Influences
- Development is shaped by both nature (biological forces) and nurture (environmental forces).
-
Arnold Gesell (1925) believed child development is determined by a maturational timetable inherited in our genetic code.
- Gesell believed a child's personality emerges through stages and natural sequences dictated by their nervous systems and biological programming.
- His theory emphasizes biological factors over environmental influences.
-
John Watson (1930), in contrast, argued that development is exclusively determined by environmental influences.
- Watson believed that any individual, given the proper environment, could be trained to become any type of specialist, regardless of their innate talents or predispositions.
- His theory prioritizes environmental learning over ingrained biological factors.
-
Maturation: This refers to the biological unfolding of an individual, encompassing both:
- Species-typical biological inheritance: This is the genetic blueprint shared by members of the same species, represented by DNA.
- Individual person's biological inheritance: This is the unique genetic code passed down from parents to offspring.
-
Learning: This encompasses experiences that lead to relatively permanent changes in thoughts, feelings, and behaviors.
- It is the process through which individuals acquire knowledge and skills based on their interactions with the environment.
Biological Influences: Maturation
- Gesell: observed the development of various motor skills in infants such as sitting, standing, and crawling, and concluded that these skills emerge in a predictable pattern, supporting the idea of a maturational process driven by biological factors.
- Jean Piaget: Proposed that cognitive development occurs through a series of stages driven by maturational processes.
- Lawrence Kohlberg: Developed a maturational model for moral development, suggesting that moral reasoning progresses across stages determined by biological factors.
Research on Twin Studies: Separating Nature and Nurture
- Comparing the traits of identical twins (who share 100% of their genetic code) and fraternal twins (who share 50% of their genetic code) helps to determine the relative contributions of genes and environment.
- Concordance Rate: This is the percentage of pairs of people where both members of the pair display the same trait, even if only one member of the pair actually has it.
- Studying identical twins, raised together or apart, reveals that they exhibit more similar intelligence test scores compared to fraternal twins or siblings raised together. This suggests that genetics play a crucial role in intelligence.
- This research methodology, analyzing twin pairs, allows researchers to separate genetic from environmental influences without directly measuring genes.
