Chapter 2: An Integrative Approach to Psychopathology Flashcards
multidimensional integrative approach
Approach to the study of psychopathology that holds psychological disorders as always
being the products of multiple interacting
causal factors.
genes
long molecules ofdeoxyribonucleic acid (DNA) at various locations on chromosomes, within the cell nucleus.
diathesis-stress model
Hypothesis that both an inherited tendency (a vulnerability) and specific stressful conditions are required to produce a disorder.
vulnerability
Susceptibility or tendency to develop a disorder.
gene-environment correlation model
Hypothesis that people with a genetic predisposition for a disorder may also have a genetic tendency to create environmental risk factors that promote the disorder.
epigenetics
The study of factors other than inherited DNA sequence, such as new learning or stress, that alter the phenotypic expression of genes.
neuroscience
Study of the nervous system and its role in behavior, thoughts, and emotions.
neuron
Individual nerve cell; responsible for transmitting information.
synaptic cleft
Space between nerve cells where chemical transmitters act to move impulses from one neuron to the next.
neurotransmitters
Chemicals that cross the synaptic cleft between nerve cells to transmit
impulses from one neuron to the next. Their relative excess or deficiency is involved in several psychological disorders.
hormone
Chemical messenger produced by the
endocrine glands.
brain circuits
Neurotransmitter currents or neural pathways in the brain.
agonist
Chemical substance that effectively increases the activity of a neurotransmitter by imitating its effects.
antagonist
In neuroscience, a chemical substance that decreases or blocks the effects of a neurotransmitter.
inverse agonist
Chemical substance that produces effects opposite those of a particular
neurotransmitter.
