Question

what are the activities that will lead the student to understand what Human Development is all about?

Answer 1

Answer:

Developmental psychology seeks to understand the influence of genetics (nature) and environment (nurture) on human development.

LEARNING OBJECTIVES

Evaluate the reciprocal impacts between genes and the environment and the nature vs. nurture debate

KEY TAKEAWAYS

Key Points

A significant issue in developmental psychology has been the relationship between the innateness of an attribute (whether it is part of our nature) and the environmental effects on that attribute (whether it is derived from or influenced by our environment, or nurture).

Today, developmental psychologists rarely take polarized positions with regard to most aspects of development; instead, they investigate the relationship between innate and environmental influences.

The biopsychosocial model states that biological, psychological, and social factors all play a significant role in human development.

Environmental inputs can affect the expression of genes, a relationship called gene-environment interaction. An individual’s genes and their environment work together, communicating back and forth to create traits.

The diathesis– stress model serves to explore how biological or genetic traits (diatheses) interact with environmental influences (stressors) to produce disorders, such as depression, anxiety, or schizophrenia.

Key Terms

trait: An identifying characteristic, habit, or trend.

genotype: That part (DNA sequence) of the genetic makeup of a cell, and therefore of an organism or individual, which determines a specific characteristic (phenotype) of that cell/organism/individual.

heritability: The ratio of the genetic variance of a population to its phenotypic variance; i.e., the proportion of variability that is genetic in origin.

innate: Inborn; native; natural.

gene: A unit of heredity; a segment of DNA or RNA that is transmitted from one generation to the next and carries genetic information such as the sequence of amino acids for a protein.
