Test One Flashcards
the science of behavior and mental processes
psychology
knowledge must be acquired through careful observation rather than from logic or intuition
empiricism
a collection of interrelated ideas and observations that together describe, explain, and predict behavior or mental processes
theory
this type of research involves describing existing events rather than performing a manipulation of an independent variable and observing changes
descriptive research methods
focus on one person-one case-which receives intense study
case studies
a technique in which researchers collect data about people in natural surroundings
naturalistic observation
research involves constructing questionnaires and administering the survey to a group of people
survey
attempt to establish the degree of a relationship between two variables
correlation studies
this school of psychological thought argued that it is necessary to study a persons total experience, not just parts of the mind or behavior
gestalt psychology
only a small segment of mental functioning
conscious
also contributes to thought and behavior by provoking slips of the tongue and by sending symbolic messages in dreams
unconscious
watson argued that psychology should focus on describing and measuring only what is observable, either directly or through assessment instruments
behaviorism
a reaction to behaviorism and its emphasis on the mechanistic nature of behavior
humanistic psychology
held that behaviorism was too restrictive in concentrating exclusively on overt behavior
cognitive psychology
emphasizes the positive values of optimism, joy, well-being, and psychological health
positive psychology
adaptation and survival of the fittest are mechanisms that produce the evolution of species
evolutionary psychology
the nervous system and heredity affect behavior and mental processes, including emotions, thoughts, and sensory experiences
biopsychology
social and cultural context influences a persons behavior, thoughts, and feelings
social and cultural
over the course of generations, the human brain and behavior have adapted in ways that allow the species to survive
evolutionary
a tendency of individuals to believe that their own ethnic or cultural group is the standard, the reference point against which other people and groups should be judged
ethnocentrism
the unwritten social and psychological guidebook that each of us learns and uses to interpret our world
culture
stress personal rather than group goals and value individual freedom and autonomy
individualist culture
favor group needs over individual ones
collectivist culture
the extent to which an individual identifies with one sex or the other
gender identity
a different concept, which describes the sexual orientation of the individual
sexual orientation
an ideological system that denies, denigrates, and stigmatizes any nonheterosexual form of behavior or identity
heterosexism
professionals who study behavior and mental processes and use behavioral principles in scientific research or in applied settings
psychologists
provide diagnosis and treatment of emotional and behavioral problems
clinical psychologists
also work with people who have emotional or behavioral problems
counseling psychologists
physicians who have chosen to specialize in the treatment of mental or emotional disorders
psychiatrists
Describe what is involved in an experiment
Independent and dependent variables, random assignments of participants, experimental and control groups
How does psychology differ from common sense?
Precisely because it is science
The group of participants who receive the new treatment
experimental group
the comparison group- the group of participants who are tested on the dependent variable
control group
Which researcher attempted to explain the causes of behavior by cataloging and describing the relationships among events in the environment, a persons animal reactions, and the establishing of the learned connection between two
B.F. Skinner (1904-1990)
This researcher published a paper in which he contended that the subject matter of psychology should be behavior, rather than the contents of consciousness
John B. Watson (1878-1958)

the nervous system is composed of billions of individual nerve cells called
neurons
(sensory neurons) which carry messages to the spinal cord and the brain
afferent neurons
(motor neurons) which carry messages from the brain and spinal cord to other structures in the body
efferent neurons
connect sensory neurons to motor neurons and outnumber both of these other types
interneurons
nourish the neurons and provide support functions
glial cells
-blank-percent of the cells in the brain are important in forming connections between neurons
90 percent
a thin, white, fatty layer that covers some large motor neurons and insulates them from other neurons
myelin sheath
the space between the axon terminals of one neuron and the dendrites, cell body, or axons of other neurons
synapse
(spike discharge) is an electrical current that travels along the axon of a neuron, initiated by the rapid reversal if the polarization of the cell membrane
action potential
chemical substances stored in synaptic vesicles
neurotransmitters
pushes the receiving neuron toward its threshold for firing
excitatory postsynaptic potential EPSP
pushes the neuron away from its threshold, making it less likely to fire
inhibitory postsynaptic potential IPSP
receptors which appear in many parts of the brain and throughout the body, indicating that this neurotransmitter is involved in many functions
acetylcholine
inhibitory neurotransmitter which is involved in a wide variety of behaviors, as well as being associated with some behavior problems
gamma-aminobutryic acid GABA
a substance derived from the amino acid tryptophan
serotonin
involved in a variety of physical processes and behaviors, which include movement, thought processes, emotion, and feelings of reward and pleasure
dopamine
plays a role in arousal reactions and acts in several parts of the brain, increasing heart rate, respiration, sweating, and dilation of the pupils in the eye
norepinephrine
