Chapter 2 Flashcards
(68 cards)
what is the sociocultural approach
approach to psychology focusing on the role of the environment, stress, and culture in producing psychopathology.
what is the biological approach
view that biological factors cause ad should be used to treat abnormality
what is the psychological approach
approach to abnormality that focuses on personality, behavior, and ways of thinking as possible causes of abnormality
what is a theory
set of assumptions about the likely causes of abnormality and appropriate treatments
what is the biopsychosocial approach
approach to psychopathology that seeks to integrate biological, psychological, and social factors in understanding and treating psychopathology
what is the diathesis-stress model
model that asserts that only when a diathesis or vulnerability interacts with a stress or trigger will disorder emerge
what is the cerebral cortex
part of the brain that regulates complex activities, such as speech and analytical thinking
what is the thalamus
structure of the brain that directs incoming information from sense receptors (such as vision and hearing) to the cerebrum
what is the hypothalamus
component of the brain that regulates eating, drinking, sex,and basic emotions; abnormal behaviors involving any of these activities maybe the result of dysfunction in the hypothalamus
what is the limbic system
part of the brain that relays information from the primitive brain stem about changes in bodily functions to the cortex, where the information is interpreted
what is the amygdala
structure of the limbic system critical in emotions such as fear
what is the hippocampus
structure of the brain involved in memory and in the stress response
what are neurotransmitters
biochemicals, released from a sending neuron, that transmit messages to a receiving neuron in the brain and nervous system
what is a synapse
space between a sending neuron and a receiving neuron into which neurotransmitters are first released (also known as the synaptic)
what are receptors
molecules on the membranes of neurons to which neurotransmitters bind
what is a reuptake
process in which a sending neuron reads orbs some of the neurotransmitter in the synapse, decreasing hate amount left in the synapse
what is degradation
process in which a receiving neuron releases an enzyme into the synapse, breaking down neurotransmitters into other biochemicals
what is the endocrine system
system of glands that produces may different hormones
what is a hormone
chemical that carries messages throughout the body, potentially affecting a person’s mood, level of energy, and reaction to stress
what is the pituitary
major endocrine gland that relies partly on the outgrowth of the brain and just below the hypothalamus; produces the largest amount of different hormones and controls the secretions of other endocrine glands
what are behavioral generics
Study of the processes by which genes affect behavior in the extent to which personality and abnormal are genetically inherited
what are polygenic
combination of many genes each of which make a small contribution to inherited trait
what are epigenetics
environmental conditions can change the expression of genes without changing the gene sequence
what are antipsychotic drugs
drugs use to treat psychotic symptoms, such as delusions, hallucinations and disorganized thinking
