biological psychology correct answers behavioral neuroscience. Is the study of biological bases
of psychological processes and behaviors
neuroscience correct answers study of the nervous system
Five major perspectives used to study the biology of behavior correct answers 1) describing
behavior
2)studying evolution of behavior
3) observing the development of behavior over the life span
4) studying biological mechanisms of behavior
5) studying applications of biological psychology, as in behavioral dysfunction.
describing behavior correct answers behavior can be described in terms of acts or processes, or in
terms of results or functions
Ex: Arm movements can be described according to the muscles that contract or by what arm is
being used for
studying evolution of behavior correct answers species can be compared to study evolution of
brain and behavior:
continuity- of behavior and biological processes (conserved characteristics) because of common
ancestry
differences- in behavior and biology that have evolved as adaptations
observing development of behavior correct answers a trait that is passed on from a common
ancestor is *conserved*
behaviors that change over the life span are studied to learn about functions and mechanisms
ontogeny correct answers is the process of growing up and growing old
Studying the biological mechanisms of behavior correct answers Each organism contains many
neurons, or nerve cells
neuronal activity is studied to understand the mechanisms underlying behavior.
Research can be applied to humans, especially in diseases of the brain
,somatic intervension correct answers alteration of a structure or function to see how behavior is
altered
administering a hormone correct answers affects strength of mating behavior
satimulate brain region electrically correct answers affects movement toward goal object
cut connections between parts of the nervous system correct answers affects recognition of a
stimulus
behavioral intervention correct answers intervention in a behavior to see how structure of the
brain or brain function is altered.
behavior is then the independent variable and body changes are dependent variables.
put male in presence of female correct answers changes in hormone levels
present a visual stimulus correct answers changes in electrical activity of brain
give training correct answers anatomical changes in nerve cells
correlation correct answers measures how much a body measure varies with a behavioral
measure- but correlation does dot imply causation
one of the approaches considered in biological psychology
neuroplasticity correct answers also called neural plasticity. describes the ability of the brain to
be changed by environment and by experience.
This can occur during development as well as in adulthood.
Dendric spines in the brain can change shape in seconds.
The role of play in brain development correct answers social interactions can result in brain
changes. In rats, social isolation leads to changes in the brain.
In humans, psychological expectation can affect the magnitude of a response.
social vs. isolation rearing conditions correct answers the amygdala area involves with
processing odors information was smaller in isolated rats
contributions of biological psychology correct answers can help us understand brain disorders
and devise treatments.
one person in five suffers from some form of neurological or psychiatric disorder.
, Clinical and laboratory approaches are both important in this research.
levels of analysis correct answers range from social interaction down to the molecular level.
reductionism correct answers breaks a system down into its smaller parts, in order to understand
it.
cells correct answers what is the nervous system composed of
neurons correct answers also called nerve cells. Are the most important part of the nervous
system.
glial cells correct answers provide support for neurons
neuron doctrine correct answers the brain is composed of independent cells (Ramón y Cajal)
information is transmitted from cell to cell across *synapses* (Sherrington)
ribosomes correct answers translate genetic instructions into proteins
input zone correct answers receives information from other cells through dendrites
integration zone correct answers *cell body* (or *soma*) region where inputs are combined and
transformed
conduction zone correct answers single *axon* leads away from the cell body and transmits the
electrical impulse
output zone correct answers axon terminals at the end of the axon communicate activity to other
cells
golgi staining correct answers Ink fills whole cell, including details but only stains a small
proportion of neurons.
fluorescent molecule injections correct answers Fills the whole cell, including details but only
stains a small proportion of neurons. Injected with florescent dye.
nissl stains correct answers outline all cell bodies because the dyes are attracted to RNA, which
encircles the nucleus.
autoradiography correct answers shows the distribution of radioactive chemicals in tissues
