Goals Of Psychology
Conducting research to describe, explain, predict, and control behavior. These goals form the basis of the psychological enterprise.
people begin life with a blank slate. psychological theory asserting that knowledge comes only or primarily via the flexibility of sensory experience. John Locke and Aristotle.
a scientific approach that limits the study of psychology to measurable or observable behavior.
theory asserting that human behavior and thinking are largely determined by irrational, unconscious drives.
psychologists who developed the psychodynamic perspective. His model was the first to recognize that human nature is not always rational and that actions may be driven by motives that are not in conscious awareness.
psychological perspective primarily concerned with observable behavior that can be objectively recorded and with the relationships of observable behavior to environmental stimuli.
perspective that stresses human thought and the processes of knowing, such as attending, thinking, remembering, expecting, solving problems, fantasizing, and consciousness.
model in which behavior is explained in terms of past experiences and motivational forces; actions stem from inherited instincts, biological drives, and attempts to resolve conflicts between personal needs and social requirements.
also known as human development, is the scientific study of systematic psychological changes, emotional changes, and perception changes that occur in human beings over the course of their life span.
34% of psychology PhD's are applied in this subfield; a branch of psychology that studies, assesses, and treats people with psychological disorders
a subdiscipline of psychology exploring internal mental processes. It is the study of how people perceive, remember, think, speak, and solve problems.
28% of psychologists work within this setting; devoted to counseling children in elementary and secondary schools who have academic or emotional problems
a branch of psychology that assists people with problems in living (often related to school, work, or marriage) and in achieving greater well-being
The application of psychological concepts and methods to optimizing human behavior in workplaces
structuralism; in 1879 founded first psychology laboratory in world at University of Leipzig; introspection, basic units of experience
behaviorism; pioneer in operant conditioning; behavior is based on an organism's reinforcement history; worked with pigeons
the perspective on mind and behavior that focuses on the examination of their functions in an organism's interactions with the environment.
cognitive psychology; disagreed with Skinner about language acquisition, stated there is an infinite # of sentences in a language, humans have an inborn native ability to develop language
study of the structure of the mind and behavior; the view that all human mental experience can be understood as a combination of simply elements or events.
a gestalt psychologist who argued against dividing human thought and behavior into discrete structures
the school of psychology that emphasizes the tendency to organize perceptions into meaningful wholes
1902-1987; Field: humanistic; Contributions: founded person-centered therapy, theory that emphasizes the unique quality of humans especially their freedom and potential for personal growth, unconditional positive regard, fully functioning person
the generation effect
Self-produced information (generated) is better remembered than information that is not self-produced.
Examples in research: fill in the missing letter for the pair of words or read the pair of words aloud.
Doctor - N rse
Applied Examples (studying):
Making note cards, creating sample test questions.
The biological process through which memories are transformed from a transient and fragile status to a more permanent and robust state; according to most researchers, occurs over the course of several hours.
Combination of both, mainly testing for best memory retention
reading/studying vs. testing the material?
A controlled procedure in which at least two different treatment conditions are applied to subjects whose behaviors are then measured and compared to test a hypothesis about the effects of the treatments on behavior.
a tentative and testable explanation of the relationship between two or more events or variables; often stated as a prediction that a certain outcome will result from specific conditions.
variable that the researcher manipulates with the expectation of having an impact on values of the other variable.
a variable that the researcher measures to assess the impact of the variation in the other variable.
a definition of a variable or condition in terms of the specific operation or procedure used to determine its presence.
group exposed to the treatment or experiences a manipulation of the independent variable.
group in an experiment not exposed to a treatment or does not experience a manipulation in the independent variable.
change in behavior in the absence of an experimental manipulation; an inert substance given to the control group in an experiment.
An experimental procedure in which both the research participant and the research staff are ignorant about whether the participants have received the treatment or the placebo.
Case study method
An in-depth examination of an individual that often involves compiling and analyzing information from a variety of sources such as observing, testing, and interviewing the person/people who knew the individual.
a research method that involves gathering information from people through the use of surveys or questionnaires.
Naturalistic observation method
method of research based on careful, unobtrusive observation of behavior in natural settings.
a research project designed to discover the degree to which two variables are related to each other.
Ex post facto method
an experiment where the researcher examines the effect of a naturally occurring treatment after it has occurred.
in an experiment, a variable, other than the independent variable, that could influence the dependent variable.
cell in the nervous system specialized to receive, process, and/or transmit information to other cells.
the extended fiber of a neuron through which nerve impulses travel from the soma to the terminal buttons.
nerve impulse activated in a neuron that travels down the axon and causes neurotransmitters to be released into a synapse.
the polarization of cellular fluid within a neuron, which provides the capability to produce an action potential.
the process during the action potential when sodium is rushing into the cell causing the interior to become more positive.
the period of rest during which a new nerve impulse cannot be activated in a segment of an axon.
insulating material that surrounds axons and increases the speed of neural transmission.
chemical messengers that traverse the synaptic gaps between neurons. When released by the sending neuron, they travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
principle that the action potential in a neuron does not vary in strength; the neuron either fires at full strength or it does not fire at all.
"morphine within"--natural, opiatelike neurotransmitters linked to pain control and to pleasure.
the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron.
Central Nervous System (CNS)
the body's primary information processing system; includes the brain and spinal cord.
Peripheral Nervous System (PNS)
part of the nervous system composed of the spinal cord and cranial nerves that connect the body's sensory receptors to the CNS and the CNS to the muscles and glands.
Autonomic Nervous System
subdivision of the PNS that controls the body's involuntary motor responses by connecting the sensory receptors to the CNS and the CNS to the smooth muscle, cardiac muscle, and glands.
Somatic Nervous System
subdivision of the PNS that connects the CNS to the skeletal muscles and the skin.
the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations.
subdivision of the autonomic nervous system that monitors the routine operation of the body's internal functions and conserves and restores body energy.
region of the brain located above the lateral fissure and in front of the central sulcus; involved in motor control and cognitive activities.
region of the brain behind the frontal lobe and above the lateral fissure; contains somatosensory cortex; processes information about temperature, touch, body position, and pain.
region of the cerebral cortex that controls the action of the body's voluntary muscles.

From Gestalt Psychology, it is the tendency for elements appearing to follow in the same direction (such as a straight line or a simple curve) to be grouped together.
