The four D’s
deviance
distress
dysfunction
danger
Deviance
Differing markedly
from a particular
society’s “norms
Distress
Often troubling to
the individual
Dysfunction
lack of control over ones experience
Danger
To oneself or
others; careless,
hostile, confused
Ancient/prehistoric views on abnormal behavior
Result of evil spirits—magical, sinister
beings
* Battle between external forces of good and evil
Trephination
use of stone instruments to
cut away a section of the skull to release evil spirits
The biological model
Emphasizes physiology
Illness brought about by malfunctioning parts of the organism
Points especially to problems in brain anatomy or brain chemistry
How do biological theorists explain
abnormal behavior?
Connections found among some psychological disorders and specific brain structures
Glutamate
Most abundant CNS excitatory
neurotransmitter; active in
learning/memory; implicated in
schizophrenia
Acetylcholine
Activates skeletal muscles; in
brain, involved in learning,
arousal, attention, memory,
motivation
Dopamine
Movement control; reinforcing
effects of food, sex, and
abused drugs; schizophrenia
and Parkinson’s disease
Serotonin
Mood, sleep/arousal, aggression,
depression, obsessive-compulsive
disorder, alcoholism
Gamma-amino-butyric acid
(GABA)
Predominant inhibitory
neurotransmitter; respond to alcohol
and benzodiazepines
(tranquilizers); deficiency is one
cause of epilepsy
Norepinephrine
A hormone released during stress.
Functions as a neurotransmitter in
the brain to increase arousal and
attentiveness to events in the
environment; involved in depression
Neuroplasticity
The ability of neural
networks in the brain to
Change through growth and reorganization
Compensate for injury
and disease
Adjust their activities in
response to new
situations or changes in
the environment
throughout the
lifespan
Three leading biological treatments today
Psychotropic medications-drugs
brain stimulation
psychosurgery
Drug therapy
1950’s: advent of psychotropic medication
antianxiety drugs, antidepressant drugs, antibipolar drugs, antipsychotic drugs
chemical activity
abnormal activity in the endocrine system is also related to mental disorders
ex- abnormal secretions of cortisol is linked to anxiety and mood disorders
strengths of the biological model
considerable respect in the field
Constantly produces valuable new
information
treatments bring great relief
weaknesses of the biological model
Limits understanding of abnormal
function by excluding nonbiological
factors
May produce significant undesirable
effects
psychodynamic model
Behavior is determined largely by
underlying, unconscious, dynamic
(interacting), psychological forces (Freud)
Id
pleasure principal
ego
ego defense
