Chapter 2 Flashcards
Multi dimensional integrated approach
Approach to psychopathology thatholds disorders as the product of multiple factors
Genes
DNA, basic unit of heredity
Diatheses-stress model hypothesis
Guess that an inhereted tendency (vulnerability) and a stressir combine to make a disorder
Vulnerability susceptibility
Tendency to develop a disorder
Gene-environment cirrelation model hypothesis
Theiry that people with a genetid preposition for a disorder may make an environment that promotes the disorder
Epigenetics
The study of factors ither than inherited DNA like learning or stress that alter phenotypic expression of genes
Neuroscience
Study of the nervous system and its impacts on behavior, thought, and emotions
Neuron
Single cell responsible for information transmission
Action potentials
Short periods of electrical activity in a neuron that sends a signal
Terminal button
The end of an axon where NT are stored before release
Synaptic cleft
Space between neurons (synaptic gap)
Neurotransmitters
Chemical that crosses the sunaptic cleft to carry signals from one neuron to another. Too much or little can contribute to mental illness
Excitatory
Activating/causing excitation
Inhibitory
Surpressing/causing inhibition
Hormone
Chemical messenger produced by the endocrine glands
Brain circuts
Neurotransmitter current/pth in the brain
Inverse agonist
Chemical substance that produces opposite effects to a neurotransmitter
Reuptake
When a neuron takes it’s NTs back after they cross the synaptic cleft
Modeling
(Observational learning) watching others reactions to a stimulus and modeling that reaction
Prepared learning
Ability to learn certain associations faster than others
Implicit memory
Condition of memory in which a person can’t recall memories but still acts on them
Fight or flight
Biological reaction to stressors that prepares bidy to respond to a threat
Emotion
Pattern of action elicited by an external event and a feeling state and a physiological response
Mood
Enduring emotion
Affect
Conscious, subjective part of emotion that accompanies an action
Circumplex model
Model describing emotions as points in a 2-dimensional space of valence and arousal
Equifinality developmental psychopathology
Principle that a disorder may have multiple causes
