I.
INTRODUCING PSYCHOLOGY
A.
What is Psychology? - The scientific study of behavior and mental processes. Psychology values
empirical evidence - information acquired by direct observation and measurement using
systematic
scientific methods and critical thinking – the process of objectively evaluating, comparing,
analyzing, and synthesizing information. Studying psychology offers practical solutions to
everyday problems and develops an appreciation for scientific methods of research, as opposed to
pseudo psychologies (“false psychologies”) that pretend to discover psychological information
through nonscientific methods.
B.
Psychology’s Goals -The four goals of psychology are: (1) Description - to describe particular
behaviors by careful scientific observation, (2) Explanation – to explain behaviors by conducting
experiments to determine their causes, (3) Prediction – to predict when a behavior being studied
will occur in the future, and (4) Change – to change inappropriate behavior or circumstances.
psychologists investigate behavior with basic research or applied research.
Psychology at Work: Careers in the Field - Psychologists can specialize in several
areas, including clinical and counseling psychology, biopsychology/neuroscience,
experimental, cognitive, developmental, industrial/organizational, educational
psychology, school psychology. A description of the different areas/specialties of
psychology is shown in Table 1.1.The number of psychologists working in the different
fields is highlighted
in Figure 1.2.
II. ORIGINS OF PSYCHOLOGY
A.
Early Psychological Science: A Brief History - Historically psychologists have taken various
approaches regarding the study of behavior. They eventually emerged to form various schools of
psychology with distinct approaches to the study of behavior. The following nine major schools
are discussed: (1) structuralism, (2) functionalism, (3) psychoanalytic/psychodynamic, (4)
behavioral, (5) humanistic, (6) cognitive, (7) neuroscience/biopsychology, (8) evolutionary, and
(9) sociocultural. The contributions of women and minorities are highlighted.
1. Structuralism - Titchener brought Wundt's ideas to America and coined the term
structuralism, which is now used to refer to the school of thought that focused on the
investigation of thought processes and the structure of the mind.
2. Functionalism - Feeling the need for practical applications of psychology, some psychologists
turned to functionalism. Functionalism focused on the function of mental processes in adapting
the individual to the environment. Darwin’s theory of evolution had an impact on this school
and William James was the leading force in the functionalist school.
3. The Psychoanalytic/Psychodynamic Perspective - Sigmund Freud's psychoanalytic theory
examined psychological problems that were presumed to be caused by conflicts in the
unconscious which are primarily sexual or aggressive in nature. The controversy surrounding
Freud's theories are briefly discussed.
4. Behavioral Perspective - The school of behaviorism that emphasized objective, observable
behavior and the rigors of scientific research. All behavior is viewed as a response to a
stimulus in the environment. Watson and Skinner were influential figures in behaviorism.
5. Humanistic Perspective – Challenging both the psychoanalytic and behaviorist views,
humanism stressed free will, self-actualization, and the positive and growth-seeking nature of
human nature.
6. Cognitive Perspective – A modern perspective that continues research interests in how we
gather, encode, and store information emphasizing the areas of thought, perception, and
information processing.
7. Neuroscience/Biopsychology Perspective – A modern perspective that explores the role of
biological factors such as genetics and biological brain processes.
8. Evolutionary Perspective – The evolutionary perspective that focuses on the role of natural
selection, adaptation, and evolution of behavior and mental processes.
9. Sociocultural Perspective – Social interactions and cultural determinants of behavior and
mental processes are emphasized in the sociocultural perspective.
B. Modern Perspectives: Seven Approaches and One Unifying Theme - Early schools of
psychology have disappeared or blended into newer, broader perspectives. The biopsychosocial
is introduced as a unifying theme of modern psychology and today, many psychologists
recognize its merit. Table 1.2 highlights seven major perspectives in contemporary psychology.
III.THE SCIENCE OF PSYCHOLOGY – Research strategies are generally seen as either basic or
applied research. Basic research is conducted to study theoretical questions without trying to solve a
specific problem. It studies behavior for its own sake – simply for knowledge. Applied research,
however, utilizes the principles and discoveries of psychology for practical purposes attempting to
find
solutions to real-world problems. Psychologists follow standardized scientific procedures in
the same way as other scientists. Psychologists strive to maintain high ethical standards in research,
therapy, and other areas of professional psychology.
A. The Scientific Method: A Way of Discovering - Generally involves six carefully planned
steps, as summarized in Process Diagram 1.1. The steps include: (1) identify question and
literature review, (2) develop a testable hypothesis, (3) select a research method and collect the
data, (4) analyze the data and accept or reject the hypothesis, (5) publish, replicate, and seek
scientific review, and (6) build a theory
B. Ethical Guidelines: Protecting the Rights of Others - Psychologists are expected to maintain
high ethical standards.The American Psychological Association (APA) has published
specific guidelines detailing these standards. Three important areas are discussed: (1) human
participants informed consent, voluntary participation, use of deception, debriefing,
confidentiality, and use of students as subjects, (2) animal rights, and (3) clients in therapy –
confidentiality.
IV. RESEARCH METHODS – Four research methods are examined: (1) experimental, (2)
descriptive, (3) correlational, and (4) biological. The advantages and disadvantages of
experimental and descriptive research methods are highlighted in Table 1.3.
A. Experimental Research: A Search for Cause and Effect - An experiment is the only research
method that can identify cause and effect.
1. Variables - Independent variables are the factors the experimenter manipulates whereas the
dependent variables are measurable behaviors of the participants.
2. Control and Experimental Condition - The control condition treats participants identically
to
participants in the experimental condition, except that they do not receive the independent
variable. In the experimental condition, all participants are exposed to the independent
variable.
3. Research problems and experimental safeguards – Research problems may include
experimenter bias, the placebo effect, ethnocentrism, sample bias, and participant bias.
Various safeguards including double-blind study, placebos, and randomization are discussed.
Research Highlight: Love at First Fright? – Research by Dutton and Aron suggest that
individuals physiologically aroused by a fear-producing situation may mistakenly
attribute their arousal to attraction. This phenomenon has come to be called the
Misattribution of Arousal Process.
Critical Thinking/Active Learning – This exercise gives readers a chance to critically
evaluate “Text Key Concepts” with “Suggested Critical Thinking Components”, such as,
gathering data.
B. Descriptive Research: Naturalistic Observation, Surveys, and Case Studies -When it is not
feasible for ethical or practical reasons to study behavior experimentally, psychologists use
descriptive techniques including: (1) naturalistic observation - used to study behavior in its
natural habitat, (2) surveys - using tests, questionnaires, and interviews to sample a wide variety
of behaviors and attitudes, and (3) case study - an in-depth study of a single research participant.
Case Study/Personal Story: A Life Without Fear? – The case of a patient
unable to recognize fear in herself and others is highlighted. This inability appears
due to damage to a part of her brain called the amygdala.
C.
Correlational Research - Correlational studies allow scientists to determine the degree of
relationship between variables. Positive, negative, and zero correlations are discussed in Concept
Diagram 1.1 and readers are strongly cautioned that correlation does not imply causation.
D. Biological Research – Tools for exploring the brain and nervous system are discussed and
highlighted in Table 1.4 including dissection, ablations/lesions, electrical recordings of brain
activity (EEG), electrical stimulation of the brain (ESB), computed tomography (CT), magnetic
resonance imaging (MRI), and positron emission tomography (PET).
Psychology at Work – Becoming a Better Consumer of Scientific Research – This
exercise gives readers a chance to evaluate popular secondary sources of information to
see if the study (1) confuses correlation with causation, (2) lacks a control group, (3)
displays experimenter bias, or (4) includes sample bias.
Gender and Cultural Diversity: Are There Cultural Universals? – Cultural
psychologists conduct research to discover which behaviors are human universals and
which are specific to individual cultures.
V. TOOLS FOR SUCCESS – This section offers well-documented tips, strategies and resources to assist
students in becoming more efficient and successful.
A.
Active Reading – Steps are outlined including (1) Familiarizing Yourself with the General Text
and (2) How to Read a Chapter which is highlighted in Process Diagram 1.3 Using the SQ4R
Method. The initials stand for six steps in effective reading: Survey, Question, Read, Recite,
Review, and wRite.
B.
Time Management- Set a balance between work, college and social life with four basic
strategies: establish a baseline; set up a realistic activity schedule; reward yourself for
good behavior; and maximize using the time you do have. -
