include causal factors from the fields of genetics and neuroscience
BIOLOGICAL DIMENSIONS
causal factors from behavioral and cognitive process, including learned helplessness, social learning, prepared learning, and even unconscious processes
PSYCHOLOGICAL DIMENSIONS
a degenerative brain disease that appears in a specific area of the brain — the basal ganglia
HUNTINGTON’S DISEASE
one of a pair of genes that strongly influences a particular trait; we need only one of them to determine a trait
DOMINANT GENE
present at birth; it is caused by the ability of the body to metabolize phenylalanine.
PHENYLKETONORIA (PKU)
must be paired with another R gene to determine a trait
RECESSIVE TRAIT
behavior and personality and even intelligence are probably _____
POLYGENIC
influenced by many genes and contributing only a tiny effect
POLYGENIC
suggested that the very genetic structure of cells may change as a result of learning if genes were inactive with the environment in such a way that it becomes active
ERIC KANDEL
individuals inherit tendencies to express certain traits or behaviors, which may then be activated under conditions of stress
DIATHESIS-STRESS MODEL
a condition that makes someone susceptible to developing a disorder
DIATHESIS
individuals that genetic endowment may increase the probability that an individual will experience stressful life events
GENE-ENVIRONMENT MODEL
also known as the gene-environment correlation model
Reciprocal - gene environment model
processes all info received from our sense organs and reacts as necessary
CENTRAL NERVOUS SYSTEM
electrical impulses that are transmitted and contains the information
ACTION POTENTIAL
space between the terminal button of an axon and the dendrite of another
SYNAPTIC CLEFT
biochemicals that are released from the axon of one neuron and transmit the impulse to another
NEUROTRANSMITTERS
do not merely insulate neurons, they play an active role in neural activity
GLIAL/GLIAL CELLS
neurotransmitters that increase the likelihood that the connecting neuron will fire
EXCITATORY
decrease the likelihood that the connecting neuron will fire
INHIBITORY
decrease in GABA
ANXIETY
increase in dopamine
SCHIZOPRENIA
increase in norepinephrine
DEPRESSION
decrease in serotonin
DEPRESSION
