A history os psychology: Schools of
Psychological thought, past and present
SCHOOL FOCUS EARLY
LEADER
STRUCTURALISM Consideres conscious experience the proper
subject matter of psychology. Used a technique
called introspection (the description and
analysis by a person of what he or she is thinking
and feeling.
WUNDT
FUNCTIONALISM Grew out structuralism and was concerned with
how and mhy the conscious mind, works; a
principal aim was to know how those contents of
consciousness worked together.
JAMES
GESTALT Suggested that conscious experience is more
than simply the sum of its parts. Focused on the
unity of perception and thinking.
WERTHEIMER
SCHOOL FOCUS EARLY LEADER
PSYCHOANALYSIS He focused on the causes and treatment of
emotional disturbances. Freud worked from the
premise the unconscious processes direct daily
behavior. He emphasized the idea that childhood
experiences influence future adult behavior and
the sexual energy fuels day – to – day behavior.
FREUD
COGNITIVE Focuses on thought processes and mental
activities involved in perception, memory,
learning, and thinking. Cognitive
psychology focuses on the mental
processes involved in behavior, such as
how people solve problems and appriaise
situations as threatening.
VARIOUS
BEHAVIORISM The behaviorists’ prespective focuses on
how observable responses are learned,
modified, and forgotten. A fundamental
assumption is that disordered behavior can
be reshaped and that appropriate,
worthwhile behavior can be substituted
throught the traditional learning
techniques.
WATSON
HUMANISTIC Emphasized the uniqueness of the human
experience and the idea that human beings have frr
will to determine their destiny.
MASLOW
BIOLOGICAL Focuses on how physical mechanisms affect
emotions, feelings, thoughts, desires, and sensory
experiences.
VARIOUS
ECLECTICISM: THE BEST OF EVERYTHING
An eclectis orientation allows a researcher or practitioner to view a problem
from several orientations. Consider Depression:
• From a biological perspective alone, people become depressed becouse of
changes in brain chemistry.
•From a behavioral poin of view alone, people learn to be depressed and sad
because of faulty reward systems in ther enviroment.
•The cognitive perspective suggests that depression is made worse by the
interpretations (thoughts) an individual might adopt about a situations.
Is Psychology a Unified Science?
►Psychology is a science that answers
important questions. To do so, it uses a
variety of methods, is flexible in explaining
behavior; accounts for the complexity of the
brain, the environment, and behavior
relations; and accommodates competing
theories. There are many specialities and
interests, but only one science of
psychology.

systematic and begins
whit a specific question.
But sometimes
unexpectedly find an

problem.
A hypothesis is a
tentative idea that
express a causal
relationship of two
events o variable.
Systematic explorations
The researchers follow up
systematically, that is they try to
consider all the aspects of a
situation that might cause an
organism to behave as it does.
Only controlled laboratory
experiments permit researches to
make cause-an effect-statements
Correllated events and causally
related events
►Two events are correlated when de
presence of a hi value of one variable o
situation is regulary asociated whit a hi, or
low value of another.
►In contrast:
►Events are causally related when one event
makes another event occur.
Significant differences: is
the statistically
determined likelihood
that a behavior not
occurred because of
chance alone
The technique they use
more than any other to
explore a cause-effect
relationship is a
controlled experiment.
Components of experiment
►Variables groups experimental and
controlled
►operational definitions sample sizes
Experiment
questionnaires interviews
naturalistic case
study
observation
Another techniques
To collect information
Strengths and weaknesses
of 5 approaches to research
Aproach Strengths Weaknesses
Experiment Manipulated the variable to
control the extraneus influences,
best method for identifying ausal
realtionships
Artificially or laboratory
envirotment, limited or
generalizability of findings,
manipulation of some variables
is unethical or impractical
Correlational study Measurement of degree of
asociation among variables;
good basis for predictions
Limited opportunity to controlled
third factors; unable to draw
conclusions about causal
relationships.
Questionarie Effective means of measuring
actions, attitudes, opinions,
preferences, and intentions of
large number of people.
Lack of explanatory power;
validity of findings may be
limitted by samples realibity
dificult to determine; self report
may be inaccurate or biased
Naturalistic observation Observation of behavior in its
natural context
Little opportunity to conrol
variables; time-consuming
Case study Study or rare events; extensive
evidence gathered on a single
person
Lack of generalizability of
findings time-consuming
