Chapter 2 Causes of Abnormal behavior Flashcards
Etiology
causes of the disorder
Biopsychosocial model
Integrates evidence from biological, psychological, and social dimensions
Biological Paradigm
abnormal behavior stems from biological causes
Psychodynamic paradigm
abnormal behavior stems from unconscious mental conflicts that are rooted in childhood experiences
Freud
sexuality in development through adolescence
Defence Mechanisms
Denial, Projection, Displacement, Sublimation, Reaction Formation, rationalization, repression
Denial
memory never occurred or did not exist
Projection
attributing one’s own feelings to others.
Displacement
feelings are transferred to a less threatening object
Reaction formation
turning a painful feeling or experience into it’s opposite
Repression
Hiding a memory away from consciousness
Sublimation
modifying an impulses into one that is socially acceptable
Rationalization
Justifying
Cognitive-Behavioral Paradigm
Abnormal behavior as a product of learning
Causality
evaluating the causes of a mental disorder based on a number of factors instead of one
Equifinality
Many routes that lead to the same disorder
Multifinality
One route that leads to many different disorderds
Diathesis-Stress Model
a disorder is activated due to a combination of a diathesis,
, stress, and risk factors.
Reciprocal causality
bidirectional causality
Neuron
billions of tiny nerve cells that serve as the building blocks for the brain
Synapse
gaps between neurons
Dendrite
branches that receive messages from other neurons
Treatment for Schizophrenia
blocks dopamine receptors
Treatment of Depression
inhibits reuptake of serotonin
Parts of the Hindbrain
Medulla
Pons
cerebellum
Hindbrain
responsible for basic bodily functions
Midbrain
responsible for motor activities
reticular activating system - sleeping waking
Forebrain
responsible for sensory, emotional, cognitive processes
Limbic System
forebrain connects to midbrain and hindbrain
responsible for emotion and learning
Hypothalamus and Thalamus
(forebrain)
medulla
blood pressure, heart rate, respiration
hindbrain
pons
stages of sleep
hindbrain
cerebellum
physical coordination
hindbrain
Reticular activating system
responsible for sleeping and waking
midbrain
Thalamus
receives and integrates sensory information from sensory organs and high brain functions
(forebrain)
Hypothalamus
controls basic biological urges for drink, eat, sex
forebrain
Cerebral hemispheres
left - language
right - spatial organization
(forebrain)
Corpus Callosum
connects left and right hemispheres
coordinates functioning
(forebrain)
Ventricles
chambers of the brain filled with cerebrospinal fluid
forebrain
cortex
frontal, parietal, occipital, temporal
frontal
reasoning, planning, emotion, speech, and movement
parietal
receives and integrates sensory information along with playing a role in spatial reasoning
occipital
receives and interprets visual information
temporal
processes smells and sounds
regulates emotion, memory, learning
Autonomic nervous system
involuntary regulates the function of various body functions
Somatic nervous system
voluntary regulates muscular control
Sympathetic nervous systems
increased arousal and energy; fight or flight
parasympathetic nervous systems
decreasing of arousal and energy
Behavior Genetics
study genetic influences on behavior
Genes
carry information on heredity
located on chromosomes
humans have 23 pairs of chromosomes
Polygenic
mental disorders are influenced by many genes
genotype
actual genetic structure
phenotype
expression of the genotype after influences such as experience and environment
Adoption studies
adopted parents vs biological parents
Natural selection
new generations adapt successfully to environmental problems
Attachment Theory
critical factor in development is quality of attachment formed between infant and parent
(bowlby)
Temperament
Openness to experience Conscientiousness Extraversion Agreeableness Neuroticism
Emotions
Joy Surprise Love Anger Fear Sadness
Modeling
learning through imitation
Operant Conditioning
punishment and rewards
Skinner
Classical Conditioning
automatic response
conditional stimulus and response - result after pairing
unconditional stimulus and response- existed prior to pairing
Pavlov
