CH 3 PP4 Crim Behavior: Bio And Neurological Flashcards
Neurotransmitters
Biochemicals directly involved in the transmission of neural impulses and without which communication would not be possible.
Serotonin
A neurotransmitter in the nervous system that usually prompts the activity of neurons.
Biopsychologists
Psychologists who study the biological aspects of behavior to determine which genetic and neurobiological variables play a part, and to what extent. They generally see human behavior as the result of a complex interaction between the individual’s neuropsychological makeup and the social environment.
Self-regulation
The ability to control one’s behavior in accordance with internal cognitive standards.
Executive function
Higher-order mental abilities involved in goal-directed behavior. They include organizing behavior, memory, inhibition processes, and planning strategies.
Neuroplasticity
The ability of the brain to change and develop new neural connections throughout life.
Behavior genetics
Examines the role genes play in the formation and development of behavior. Distinguishes genetic from environmental influences.
Molecular genetics
Studies the structure and function of genes at the molecular level.
Fraternal twins
Twins who develop from two different fertilized eggs; also call dizygotic twins
Identical twins
Twins who develop from a single egg and share the same genes; also called monozygotic twins.
Shared environment
An important concept in twin studies, this refers to the prenatal and life experiences that are common to both twins, such as being raised by the same biological parents.
Nonshared environments
An important concept in twin studies, this refers to the living experiences that are different for each twin, such as being raised by different parents.
Twins: Concordance
—Degree to which twin pairs show to have the same trait
Ex: Both twins decide to nave the same hair style
The 2 twins like the same stuff
They have a higher level of crime rates together.
A term used in genetics to represent the degree to which related pairs of subjects both show a particular behavior or condition.
It is usually expressed in percentages.
Twins’ Early Development Study (TEDS)
Ongoing study of twins examining behavior and cognitions from early childhood through adolescence.
MAOA and MAOA-L gene
Gene that is believed to play an instrumental role in antisocial behavior, either preventing it or—in low form—contributing to such behavior.
Psychophysiology
The study of the dynamic interactions between behavior and the autonomic nervous system.
Amygdala
Part of brain that regulates fear and other emotional responses.
Fetal alcohol spectrum disorder (FASD)
Broad term for a continuum of conditions that result from alcohol exposure in utero.
