Chapter 1.1 Flashcards
What is the Biopsychosocial Model?
A model that considers biological, psychological, and social factors in understanding health and illness
This model emphasizes the interaction between these factors.
What constitutes a biological event in the context of thoughts and behaviors?
The characteristic anatomical structure and biological function of a person’s body
This includes the brain’s anatomy and neurotransmitter functions.
What is genomics?
The study of genomes, the complete set of genes or genetic material present in a cell or organism
This field examines how genes interact with each other and the environment.
What drives trait and behavior development from an evolutionary perspective?
Adaptation and reproductive success
These factors influence which traits are passed on to future generations.
True or False: Biology and behavior occur in a vacuum.
False
They constantly interact with each other.
What are considered the most important traits in the context of the Biopsychosocial Model?
Epigenetic traits
These traits are influenced by environmental factors affecting gene expression.
What role do gene promoters play?
They regulate the expression of genes
Gene promoters can enhance or inhibit gene activity.
What is the MAOA gene associated with?
The regulation of neurotransmitters, which can influence mood and behavior
Variations in this gene have been linked to aggression and impulsivity.
What is DNA methylation?
A biochemical process that modifies the DNA and affects gene expression
It can silence genes or alter their activity.
What does epigenetic research focus on?
How environmental factors influence gene expression
This includes studying how lifestyle, nutrition, and stress affect genetics.
What are gene-environment effects?
Interactions between genetic predispositions and environmental factors
These effects are crucial for understanding individual differences in behavior and health.
What is the significance of expressed and silenced genes?
They determine which traits are visible and how organisms respond to their environment
The balance between expression and silencing can affect health and behavior.
