CAUSES AND CRITERIA OF ABNORMALITY Flashcards
What are the three causes of abnormal behavior?
Biochemical imbalance, Genetic predisposition and Familial Transmission
It is neurotransmitter dysregulation
Biochemical imbalance
It is carried by genetic material
Genetic predisposition
It is genetic transmission of disorder
Familial Transmission
Explain the five criteria to identify abnormality
- Violation of social norms - doesnt conform to standards
- Statistical rarity - falls outside the normal probability curve
- Personal distress - causes distress from self and others
- Maladaptiveness of behavior - cant do the daily functioning
- Danger - causes harm to self and others
What are the four major categories of abnormal behavior?
POFN Psychoses Organic Functional Neuroses
It is loss of reality with psychotic features
It has distortion of reality
Psychoses
Structural damage to brain
Organic
Unknown structural damage
Functional
It is loss of reality
based on conflicts that cause anxiety
Neuroses
What are the three factors of abnormality?
Predisposing, Precipitating and Perpertuating factors
The effect is remote
Predisposing factor
The effect is immediate
Precipitating factor
Factors that make a person to be SUSCEPTIBLE or to develop a mental disorder
Predisposing factor
Factors that TRIGGERS to develop manifestation of disorder
Precipitating factor
Factors that MAINTAIN the disorder
Perpertuating factor
A perspective that believes disorder have organic and physical cause.
The approachers are genetics, neurotransmitters, neurophysiology, neuroanatomy, biochemistry etc.
Biological Perspective
It is the first neurotransmitter discovered
Involved in transmitting nerve impulses to the MUSCLES throughout the body
Acetylcholine
TOO MUCH Acetylcholine
Depression
LESS Acetylcholine in hippocampus
Dementia
A neurotransmitter related to rewards and motivation, involved in movement, emotion, memory and thinking
Dopamine
TOO MUCH Dopamine
Schizophrenia
LOW LEVEL Dopamine
Depression and Parkinson’s disease
A neurotransmitter that is inhibitory and reduces neuronal excitatory in the nervous system
GABA
