DOMAIN 1: INTRODUCTION TO PSYCHOLOGY
Objective 1.1
Define psychology.
Key Terms
 Psychology: the scientific study of the mind and behavior. Psychologists use the
scientific method to acquire knowledge.
 Levels of explanation:
o Lower levels: tied to biological influences (chemicals in the brain)
o Middle levels: interpersonal, abilities and characteristics of individuals (depending
on situation of each person)
o Highest levels: social groups, organizations, cultures (sex, race, etc.)
Exercises
1. Put a check mark by each statement that is true regarding psychology.
__o__ Psychologists study human behavior.
__o__ Psychologists study animal behavior.
__o__ Psychologists study emotions and mental processes.
_____ Psychology and "common sense" lead to the same conclusions about behavior and mental
processes.
_____ Psychology is not a science.
1
Objective 1.2
Define the scientific method and explain how it is used in psychology.
Key Terms
 Scientific method: set of assumptions, rules, and procedures that scientists use to conduct
empirical research. Scientific method demands procedure to be objective (free from
personal bias or emotions of the scientist).
 Type of psychologists and how they use the scientific method:
o Research psychologists: use scientific methods to create new knowledge about
causes of behaviors
o Practitioners: use existing research to help solve problems
o Academic psychologists: use research findings as evidence to support theoretical
concept
 Data: information gathered through observation or measurement.
 Hypothesis: tentative explanation of how or why something happens. An if-then
statement is a hypothesis.
o Conceptual variables: abstract ideas
o Measured variables: numbers that represent conceptual variables.
 Theory: integrated set of principles that explains and predicts many observed
relationships within a given domain of inquiry
Exercises
1. What is the main purpose of the scientific method?
Psychologists use the scientific method to acquire knowledge by providing a framework
for developing, organizing, and sharing information. Since the research is designed to be
repeated or appended to, it results in the refinement of the scientific knowledge.
2
2. The steps of the scientific method are (1) identify a problem or research question, (2) design a
study, (3) collect data, (4) analyze data, (5) draw conclusions, and (6) communicate findings.
Identify the step associated with each of the following activities:
__3__ Dr. Lopez noted "absent" or "present" by each student's name on his class roll at each
class meeting. He recorded students' exam scores on his roll sheet as well.
__1__ Dr. Lopez hypothesized that students who consistently attend class get higher grades than
those who are absent more often.
__6__ Dr. Lopez published the results of his study in the Journal of Community College
Teaching.
__4__ Dr. Lopez calculated the correlation between his students' rates of absence and their exam
scores and found that the two variables were positively associated.
__2__ Dr. Lopez planned to track students' attendance and exam scores and to correlate these
two variables at the end of the semester.
__5__ Dr. Lopez inferred that the data he collected supported his hypothesis regarding the
relationship between attendance and exam scores.

increase or decrease
 Negative correlations mean variables move
in opposite direction
 Zero correlation indicates no relationship
2. Classify each of the following as an example of (a) naturalistic observation, (b) laboratory
observation, (c) case study, (d) survey, or (e) correlation.
a. A professor compared his students' attendance rates to their grades. She found that students
with fewer absences tended to get higher grades. (e)
b. Psychologists studying aggression in early childhood found that an average of four instances
of hitting or pushing occurred during each hour that they spent watching a group of two-yearold’s interact in a day-care classroom. (a)
c. A telephone poll found that 37% of respondents had a favorable opinion of "Sparkle"
toothpaste. (d)

variables, there will always be the possible existence of common-causal variables and
reverse causation
10
Objective 1.6
Define representative sample and explain why it is important.
Key Terms
 Sample: people chosen to participate in the research
 Population: everyone that researcher wishes to know about
 Representative sample: representation of the population within a sample. Representative
sample must take into consideration the diversity of the population to produce a more
accurate result
Exercises

red. All of the M&Ms in Barry's bag are the (sample/population) of M&Ms. The three that he
took out are the (sample/population).
2. Each bag of M&Ms has candies of several colors. Thus, the three red M&Ms that Barry took
out of his bag (are/are not) a representative sample.
3. Why are researchers concerned about the representativeness of the samples in their studies?
a. They don't want to offend anyone.
b. They hope to generalize the findings of their studies to populations of interest.
c. Representative samples are usually large enough to ensure statistical significance.
d. Scientific journals will not publish a study unless the sample is representative.
11
Objective 1.7
Describe the experimental method, state its advantages and disadvantages, and distinguish between
independent and dependent variables.
Key Terms
 Experimental research: find the impact of experimental manipulation on dependent variable.
Provide definitive conclusions from correlational research
o Types of variable in experimental research:
 Dependent variable: measured variable that is expected to be influenced by the
experimental manipulation
 Independent variable: causing variable that is created or manipulated by the
experimenter
 Causal hypothesis: hypothesis that specify a relationship between two variables in which
changes in one variable cause changes in the other
 Experimental group: receives some amount of the independent variable
 Control group: comparison group, receives a different amount of the independent variable than
the experiment group, often zero
 Random assignment: most common method of creating equivalence among the experimental
conditions. Participants are assigned to a group through a random process. This is to make sure
the groups are equivalent on average on all possible variables.
Exercises
1. What is the primary advantage of the experimental method?
It allows the drawing of conclusions about the causal relationships among variables.
2. Read the scenario and answer the questions that follow it.
12
In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep
volunteers awake for variable amounts of time. One group of participants was kept awake for 24
hours, and the other was kept awake for 48 hours. During periods of forced wakefulness,
participants were required to engage verbal learning tasks such as memorizing the definitions of
obscure English words. At the conclusion of the period of forced wakefulness, participants were
allowed to sleep for as long as they wanted to. When participants awakened, researchers tested
them on the learning tasks they completed during the periods of forced wakefulness. The
researchers discovered that participants who were deprived of sleep for 48 hours recalled less
than those who had been forced to remain awake for 24 hours.
1a. What is the independent variable? Time participant was forced to stay awake
1b. What is the dependent variable? How well participants were able to recall the words
1c. What is the control group? The group who was kept awake for 48 hours
1d. What is/are the experimental group(s)? The group who was kept awake for 24 hours
3. Why is random assignment critical to the experimental method?
To make sure the groups on average are equivalent, eliminating the influence of
common-causal variables
13
Objective 1.8
Explain the rationale behind placebo-controlled experiments.
Key Terms
 Placebo: a treatment that has no effect on the dependent variable
 Placebo effect: when the control group participants are found to have responded to the
placebo. It results in a change in the outcome that’s due to the participant’s expectations
rather than to the effectiveness of a treatment.
 Experimenter bias: experimenter subtly treats the research participants in the various
experimental conditions differently, resulting in an invalid confirmation of the research
hypothesis. A threat to the validity of a research experiment. This can be avoided if the
experimenter is blind to condition, meaning that they don’t know which conditions the
participants are assigned to.
 Double-blind technique: a variation of the condition blindness where both researchers and
participants are unaware of which subjects are receiving the active treatment.
 Statistical significance: the confidence with which a scientist can conclude that data are not
due to chance or random error.
Exercises
1. Why do researchers use placebos and double-blind designs?
To ensure there is no experimental bias thus proving the validity of the experiment.
2. Read the scenario and answer the questions.
Sam's psychology professor, Dr. Smith, recruited him to serve as a research assistant. Sam's
job was to teach study participants a new strategy for studying textbook material. Experimental
group participants were supposed to be taught the new strategy, while control group
14
participants were to be told that they could increase their test scores by holding their textbooks
at a particular angle when reading. Each group was allowed to practice the techniques they
were taught on a chapter in a psychology textbook, after which Sam tested them over what they
had studied. Dr. Smith was surprised to discover that the control group scored higher on the
tests than the experimental group did.
(A) Did Dr. Smith's design include a placebo? Yes
(B) If so, what was the placebo? Holding the textbook at a particular angle when reading
(C) What term refers to the outcome of Dr. Smith's study? The placebo effects
(D) Would it be correct to conclude that the procedure that was taught to the control group is a
useful study strategy? If not, what is the correct conclusion? No. Sam’s experiment suffered
experimenter bias because Sam knows which group received the placebo and therefore is not blind
to condition. Sam also told the control group of the effectiveness of the placebo which leads to the
placebo effect.
15
Objective 1.9
Outline the ethical standards that psychological researchers must follow.
Key Terms
 Ethical codes:
o Legality: research doesn’t violate any law
o Institutional approval: colleges or organizations need to have an institutional review
board to make sure of the ethics of a research
o Informed consent: participants must be made aware of risks or purpose of a research
o Deception: participants must be debriefed at the end of a research
o Participants under another’s authority: those who participated through a third party
must be free do join or leave research at any time. Those who opted out of the
research must be treated equally
o Payment for participation: participants should be compensated for their time
o Confidentiality: ensuring participants’ privacy
o Publication: results of research should be made publicly available
o Animal welfare: must protect animal from excessive discomforted and animals
should be cared for by trained professional
Exercises
Read the following statements and place a checkmark beside those that violate the APA code of
ethical conduct in animal or human research.
1. _____ A researcher has been approved to collect data at a shopping mall.
2. __o__ During new student orientation, a researcher appears before an assembly of orientation
participants and asks them to complete a survey of racial attitudes. Some students receive a survey
with a cover page that states that they must write their names on the survey so that their responses
16
can be sent to the university counseling center to determine whether they are in need of cultural
sensitivity training. The cover page on the other students' surveys state that their responses are
anonymous. After collecting the surveys, the researcher discloses that the study was about the
effects of anonymity on survey responses and that none of the students' responses will actually be
sent to the counseling center.
3. __o__ An elementary school principal conducted a study of reading skills at her school in order
to complete her doctoral dissertation. Since she was the school's chief administrator, she assumed
that she did not need to get students' or parents' permission to carry out the study.
4. __o__ A researcher did a study in which intelligence tests were administered to all participants.
She refused to allow participants access to their test results because she feared that they might be
upset by them.
5. __o__ A researcher sacrificed his subjects (rats) by depriving them of food them at the end of
the study so that he could obtain additional data on how long a rat can live without food.
17
DOMAIN 2: BIOLOGY AND BEHAVIOR
Objective 2.1
Describe the various methods for studying the brain and its functions.
Key Term
 Electroencephalograph (EEG): less invasive of the lesions approaches, EEG is a technique
that records the electrical activity produced by the brain’s neurons through the use of
electrodes that are placed around the research participant’s head. It can track brain waves
when the subject engages in different activities. Advantage: subject can move around and
researchers can observe changes over fast time periods. Disadvantage: does not provide a
clear image of the structure of the brain.
 Computerized axial tomography (CAT or CT scan): uses X-ray tube to encircle the head and
produce cross sectional series of X-rays which are then combined to get a 3D image of brain
structures. Only produce static image.
 Magnetic resonance imaging (MRI): magnetic fields used to differentiate between types of
tissue in the brain. Less dangerous than CT scan as it does not expose patients to X-ray.
Only produce static image.
 Positron emission tomography (PET scan): monitors decay of a radioactive isotope injected
into the patient. Often combined with CT scans or MRIs to allow radiologists to see how the
brain is functioning.
 Functional magnetic resonance imaging (fMRI): type of brain scan that uses magnetic field
to create images of brain activity in each brain area. Detects the amount of blood flow in
each brain region to project neural activity. Can produce clear, detailed pictures of brain
structures. Noninvasive. Most commonly used method of learning about brain structure.
