Chapter 2 Flashcards
Parts of Multidimensional Approach
Behavioral, Biological, Emotional, Social, or Developmental influences
Diathesis-Stress Model
Genetic Predisposition (Diathesis) in combination with environmental factors (stressors) contribute to disorders
Gene-Environment Correlation model
People with disposition for a disorder (diathesis) also have a tendency to create environmental risk factors, feeding into the likelihood of disorder
Epigenetics
Environment alters gene expression early in life
Nature and Nurture
Hindbrain
Medulla, Pons, and Cerebellum
Controls Automatic activities
Midbrain
Controls arousal and attention
Thalamus and Hypothalamus
Behavior and emotion
Limbic system
Emotions and basic desires
Basal ganglia
Regulate motor activity
Excitatory Neurotransmitters
Increase neuron activity
Inhibitory Neurotransmitters
Decrease neuron activity
Brain circuits
Neural pathways within the brain
Agnostic Drugs
Mimic a neurotransmitter and increase its effect
Antagonist Drugs
Block a neurotransmitter and reduce its effects
Inverse Agonists
Produce opposite effects to target neurotransmitter
Glutamate
Amino acid neurotransmitter
Increases neuron activity
Gamma-Aminobutyric Acid (GABA)
Amino acid neurotransmitter
Inhibits neuron activity
Benzodiazepines
Drug that assists GABA activity
Used to treat anxiety
Serotonin
Monoamine neurotransmitter
Influences behavior, mood, and information processing
Low serotonin- Less inhibition; Instability, impulsive, overreaction, aggression, overeating, suicide, etc.
Selective Serotonin Reuptake Inhibitors (SSRI)
Increase serotonin levels by reducing breakdown between cells
Used to treat anxiety, mood, and eating disorders
Common names: Prozac, Lexapro
Norepinephrine
Monoamine Neurotransmitter
Trigger alpha-adrenergic and beta-adrenergic receptors
Controls autonomic nervous system
Dopamine
Monoamine neurotransmitter
High dopamine is associated with schizophrenia, addiction, depression, and ADHD
Low dopamine is associated with Parkinson’s Disease
Pleasure-seeking drug
Cognitive Science
How we acquire and process information
Very complex learning that depends on the environment
Learned Helplessness
When we decide that we have no control over the environment and that actions have no outcome
Causes uncontrollable stress
Outlook on life impacts stress
