COMER & COMER
Causal Factors, Models and Approaches
Model A set of assumptions and concepts that help scientists
explain and interpret observations. Also called a paradigm.
The Models:
Biological Model which sees a physical process as key to
human behavior.
Psychodynamic Model focuses on people’s unconscious
internal processes and conflicts.
Cognitive-behavioral model emphasizes behavior, the ways in
which it is learned, and the thinking that underlies behavior
Humanistic-existential model stresses the role of values and
choices.
Sociocultural model looks to social and cultural forces as the
keys to human functioning.
Family-social perspective which focuses on an individual’s
family and social interactions
Multicultural perspective which emphasizes an individual’s
culture and the shared beliefs, values, and history of that
culture.
BIOLOGICAL MODEL
biological theorists view abnormal behavior as an illness
brought about by malfunctioning parts of the organism
Neuron A nerve cell.
Synapse The tiny space between the nerve ending of one
neuron and the dendrite of another.
Neurotransmitter A chemical that, released by one neuron,
crosses the synaptic space to be received at receptors on the
dendrites of neighboring neurons. (serotonin, epinephrine,
glutamate, etc.)
Receptor A site on a neuron that receives a neurotransmitter.
Brain Chemistry and Abnormal Behavior
Process
Neurons (nerve cell) and support cells called glia
(sending electrical impulse; neuron to neuron)
Received by Neuron’s dendrites (at the end of neuron)
Neuron’s axon
Transmitted through the nerve ending at the end of the axon
to the dendrites of other neurons
Abnormal activity by certain neurotransmitters is
sometimes tied to mental disorders.
Mental disorders are sometimes related to abnormal
chemical activity in the body’s endocrine system like
imbalance hormones.
Hormones The chemicals released by endocrine glands into
the bloodstream.
Brain Anatomy, Circuitry and Abnormal Behavior
Particular psychological disorders sometimes linked to
problems in specific structures of the brain.
Ex: Huntington’s disease- a disorder marked by involuntary
body movements, violent emotional outbursts, memory loss,
suicidal thinking, and absurd beliefs — has been linked in part
to a loss of neurons in two brain structures, the basal ganglia
and the cerebral cortex.
Brain Circuit- is a network of particular brain structures that
work together, triggering each other into action to produce a
distinct behavioral, cognitive, or emotional reaction.
key to psychological disorders rather than on dysfunction
within a single brain structure or by a single brain
chemical.
Proper interconnectivity (communication) among the
structures of a circuit tends to result in healthy
psychological functioning, whereas flawed
interconnectivity may lead to abnormal functioning.
Sources of Biological Abnormalities
Genetics and Abnormal Behavior
23 pairs of chromosome with each chromosome
(contains genes) in a pair inherited from one of the
person’s parents.
Several or more genes combine to help produce our
actions and reactions, both functional and dysfunctional.
Gene combinations can contribute to one’s mental
disorder.
Genes Chromosome segments that control the characteristics
and traits we inherit.
Evolution and Abnormal Behavior
Human reactions and the genes responsible for them
have survived over the course of time because they have
helped individuals to thrive and adapt.
The very genes that helped their ancestors to survive and
reproduce might now leave these individuals particularly
prone to fear reactions, anxiety disorders, or related
psychological patterns.
Evolutionary perspective is controversial in the clinical
field
Mutation An abnormal form of the appropriate gene that
emerges by accident.
Biological Treatments
When behaving abnormally biological practitioners look for:
family history, possible genetic predisposition & event that
could have physiological effect.
