Study Notes
Biological Approach
- Views humans as biological organisms, providing biological explanations for psychological functioning and behavior.
Gene
- A DNA segment located on chromosomes that carries genetic information, inherited from parents to offspring.
Genotype
- Represents the genetic constitution of an individual, consisting of the genes received from both parents.
Phenotype
- Refers to the observable traits of an individual, resulting from the interplay between genetics and environmental factors.
Natural Selection
- A mechanism by which advantageous inherited traits enhance reproductive success, leading to those traits becoming prevalent in the population over generations.
Evolution
- The process through which inherited traits change over time due to natural selection, impacting species over long periods.
Nervous System
- A complex network that transmits messages throughout the body using nerve cells and electrical impulses.
The Brain
- Composed of clusters of neurons that collaborate to process sensory input and generate responses.
Neurotransmitters
- Biochemical substances released at synapses to facilitate the transmission of electrical signals between neurons.
Hormones
- Chemical messengers produced by the endocrine system that regulate various biological processes and states in the body.
Twin Studies
- Research studies that assess the genetic influence on traits by comparing the similarities between monozygotic (MZ) and dizygotic (DZ) twins.
MZ Twins
- Identical twins formed from a single zygote that divides into two embryos, sharing the same genetic material.
DZ Twins
- Fraternal twins who develop from two separate eggs fertilized by two different sperm, possessing different genetic makeup like regular siblings.
Concordance Rate
- Reflects the proportion of twins that share a specific trait, providing insights into the genetic contribution to that trait.
