Exam 1 Flashcards
abnormal psychology
the scientific study of human behavior that is rare, unusual, bizarre, distressing, harmful, or maladaptive
abnormal behavior
behaviors that are rare, unusual, bizarre, distressing, harmful, or maladaptive
- Deviation from what is considered normal in a sociocultural context
- Statistical deviation
- Deviation from ideal mental health
probabilistic vs deterministic statements
- probabilistic statements are derived from probability which is based on the randomness in occurrence of events.
- deterministic statements are statements derived from known causes of events.
practical reasons for defining abnormality
- Discomfort: physical/psychological pain or distress
- Deviance: bizarre/unusual behavior
- Dysfunction: inability/loss of ability to perform one’s normal roles
developmental and sociocultural contexts for determining abnormality
- we have to think of the abnormal behavior in context:
- developmental:
ex: it’s normal for infants/toddlers to get extremely upset over something small; while it may be irrational and abnormal for an adult to get that upset over the same small occurrence - sociocultural contexts:
ex: peoples behaviors can depend on different life events; if someone is extremely happy it could be due to a major event like a wedding or having a baby; if someone is acting extremely sad/depressed it could be due to the loss of a loved one, natural disasters, etc
complexity, ambiguity
it is hard to determine what is an abnormal because you have to take context and sociocultural norms into consideration
cultural relativism, determinism
-determinism:
Conceptual definitions:
-Deviation from what is considered normal in a sociocultural context
-Statistical deviation
-Deviation from ideal mental health
-Cultural perspective
•Culture is shared learned behavior transmitted from generation to generation.
•Culture is a powerful determinant of how behavior is defined and treated.
•Cultural universality: Origins, processes, manifestation of disorders are the same across cultures.
•Cultural relativism: What is normal/abnormal varies from culture to culture.
medical student syndrome
medical students perceive themselves to be experiencing the symptoms of a disease that they are studying
helpers and clients
are not two distinct populations of people
drapetomania
“mental illness” of slaves who “craved freedom”
neuron
-Cell body: the cell’s life support center
-Dendrites: receive messages from other cells
-Axon: passes messages away from the cell body to other neurons, muscles, or glands
-Neural impulse: electrical signal traveling down the axon
-Myelin sheath: covers the axon of some neurons and helps speed neural impulses
Terminal branches of axon: form junctions with other cells
Neurotransmission
- Synapse: a junction between the axon tip of the sending neuron and the dendrite (or cell body) of the receiving neuron. This tiny gap is called the synaptic gap or cleft
- Neurotransmitters released from the sending neuron travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing it to generate an action potential
- Reuptake: neurotransmitters in the synapse are reabsorbed into the sending neurons through the process of reuptake. This process applies the brakes on neurotransmitter action
- Lock and key mechanism: neurotransmitters bind to the receptors of the receiving neuron in the lock and key mechanism
serotonin
serotonin pathways are involved with mood regulation
dopamine
dopamine pathways are involved with diseases such as schizophrenia and Parkinson’s disease
SSRIs
selective serotonin reuptake inhibitors; are antidepressants that affect serotonin levels in the brain
endocrine system
the body’s “slow” chemical communication system.
hypothalamus
controls the endocrine system
hormones
synthesized by the endocrine glands are secreted in the bloodstream, and affect the brain and many other tissues.
Thomas Insel’s TED talk on mental illness
“it is crucial to stop thinking about ‘mental disorders’ and start understanding them as ‘brain disorders.’”
parts of the brain
- Brainstemis the oldest part of the brain, beginning where the spinal cord swells and enters the skull. It is responsible for automatic survival functions.
- limbic system is a doughnut-shaped system of neural structures at the border of the brainstem and cerebrum, associated with emotions such as fear, aggression and drives for food and sex. It includes the hippocampus, amygdala and hypothalamus
- Hypothalamus: regulates maintenance functions like hunger and thirst, body temperature and emotional control. Controls the pituitary gland and thus the endocrine system
- Amygdala has to do with the emotional processing
- Cortex: each brain hemisphere is divided into four lobes that are separated by prominent fissures. These lobes are the frontal lobe (forehead), parietal lobe (top to rear head), occipital lobe (back head) and temporal lobe (side of head)
relationship between brain and behavior
- auditory cortex: active when people hallucinate sounds
- visual cortex becomes active when people look at faces
- aphasia is an impairment of language, usually caused by left hemisphere damage either to Broca’sarea (impaired speaking) or to Wernicke’s area (impaired understanding).
