Psychology Final Exam Review
Chapter 4 – Nature, Nurture and Human Diversity
1. Behavior genetics, p. 134 - the study of the relative power and limits of
genetic and environmental influences on behavior.
2. Environment, p. 134- every nongenetic influence, from prenatal nutrition to
the people and things around us.
3. Chromosomes, p. 134- threadlike structures made of DNA molecules that
contain the genes.
4. DNA (deoxyribonucleic acid), p. 134 - a complex molecule containing the
genetic information that makes up the chromosomes.
5. Genes, p. 134 - the biochemical units of heredity that make up the
chromosomes; a segment of DNA capable of synthesizing a protein.
Environmental events “turn on” genes, rather like hot water enabling a tea bag to
express its flavor. When turned on, genes provide the code for creating protein
molecules, the building blocks of physical development.
6. Genome, p. 135 - the complete instructions for making an organism,
consisting of all the genetic material in that organism’s chromosomes.
7. Identical twins, p. 135 - twins who develop from a single fertilized egg that
splits in two, creating two genetically identical organisms.
• Although identical twins have the same genes, they don’t always have the
same number of copies of those genes. That may help explain why one twin may
be more at risk for certain illnesses (Bruder et al., 2008).
Most identical twins share a placenta during prenatal development, but one of
every three sets has two separate placentas. One twin’s placenta may provide
slightly better nourishment, which may contribute to identical twin differences
(Davis et al., 1995; Phelps et al., 1997; Sokoll et al., 1995).
8. Fraternal twins, p. 135 - twins who develop from separate fertilized eggs.
Theyare genetically no closer than brothers and sisters, but they share a fetal
Shared genes can translate into shared experiences. A person whose identical
twin has Alzheimer’s disease, for example, has a 60 percent risk of getting the
disease; if the affected twin is fraternal, the risk is only 30 percent (Plomin et al.,
Are identical twins, being genetic clones of one another, also behaviorally more
similar than fraternal twins? Studies of thousands of twin pairs in Sweden,
Finland, and Australia provide a consistent answer: On both extraversion
(outgoingness) and neuroticism (emotional instability), identical twins are much
more similar than fraternal twins.
9. Temperament, p. 139 - a person’s characteristic emotional reactivity and
10. Heritability, p. 140 - the proportion of variation among individuals that we can
attribute to genes. The heritability of a trait may vary, depending on the range
of populations and environments studied. 11. Interaction, p. 142- the interplay that occurs when the effect of one factor
(such as environment) depends on another factor (such as heredity).
12. Molecular genetics, p. 142 - the subfield of biology that studies the
molecular structure and function of genes.
13. Evolutionary psychology, p. 143 - the study of the evolution of behavior and
the mind, using principles of natural selection.
14. Natural selection, p. 143 - the principle that, among the range of inherited
trait variations, those that lead to increased reproduction and survival will
most likely be passed on to succeeding generations.
15. Mutation, p. 144- a random error in gene replication that leads to a change.
16. Gender, p. 146- in psychology, the biologically and socially influenced
characteristics by which people define male and female.
17. Culture, p. 153- the enduring behaviors, ideas, attitudes, values, and
traditions shared by a group of people and transmitted from one generation to
18. Norm, p. 154- an understood rule for accepted and expected behavior.
Norms prescribe “proper” behavior.
19. Personal space, p. 154 - the buffer zone we like to maintain around our
20. Individualism, p. 155 - giving priority to one’s own goals over group goals
and defining one’s identity in terms of personal attributes rather than group
21. Collectivism, p. 155 - giving priority to goals of one’s group (often one’s
extended family or work group) and defining one’s identity accordingly.
22. Aggression, p. 160- physical or verbal behavior intended to hurt someone.
23. X chromosome, p. 162- the sex chromosome found in both men and women.
Females have two X chromosomes; males have one. An X chromosome from
each parent produces a female child.
24. Y chromosome, p. 162 - the sex chromosome found only in males. When
paired with an X chromosome from the mother, it produces a male child.
25. Testosterone, p. 162- the most important of the male sex hormones. Both
males and females have it, but the additional testosterone in males stimulates
the growth of the male sex organs in the fetus and the development of the
male sex characteristics during puberty.
26. Role, p. 164- a set of expectations (norms) about a social position, defining
how those in the position ought to behave.
27. Gender role, p. 164- a set of expected behaviors for males or for females.
28. Gender identity, p. 165 - our sense of being male or female.
29. Gender typing, p. 165social learning theory, p. 165 - the acquisition of a
traditional masculine or feminine role.
30. Social learning theory, p.165 - the theory that we learn social behavior by
observing and imitating and by being rewarded or punished. Chapter 5 – Developing Through the Lifespan

cognitive development (from about 6 or 7 to 11 years of age) during which
children gain the mental operations that enable them to think logically about
20. Formal Operational Stage (p.185): in Piaget’s theory, the stage of
cognitive development (normally beginning about age 12) during which people
begin to think logically about abstract concepts.
21. Autism (p.187): a disorder that appears in childhood and is marked by

the distributions of many physical and psychological attributes. Most scores fall
near the average, and fewer and fewer scores lie near the extremes.
15. Reliability (p.421): the extent to which a test yields consistent results, as
assessed by the consistency of scores on two halves of the test, or on retesting.
16. Validity (p.421): the extent to which a test measures or predicts what it is

1. Personality (p.553): An individual’s characteristic pattern of thinking,
feeling, and acting.
2. Free Association (p.554): In psychoanalysis, a method of exploring the
unconscious in which the person relaxes and says whatever comes to
mind, no matter how trivial or embarrassing.
3. Psychoanalysis (p.554): Freud’s theory of personality that attributes
thoughts and actions to unconscious motives and conflicts; the techniques
used in treating psychological disorders by seeking to expose and
interpret unconscious tensions.

unacceptable thoughts, wishes, feelings and memories. According to
contemporary psychologists, information processing of which we are
5. Id (p.555): Contains a reservoir of unconscious psychic energy that
according to Freud, strives to satisfy basic sexual and aggressive drives.
The id operates on the pleasure principle, demanding immediate
gratification. 6. Ego (p.555): The largely conscious, “executive” part of psychology that,
according to Freud, mediates among the demands of the id, superego,
and reality. The ego operates on the reality principle, satisfying the id’s
desires in ways that will realistically bring pleasure rather than pain.
7. Superego (p.555): The part of personality that, according to Freud,
represents internationalized ideals and provides standards for judgement
(the conscience) and for future aspirations.
8. Psychosexual Stages (p.556): the childhood stages of development
(oral, anal, phallic, latency, genital) during which, according to Freud, the
id’s pleasure-seeking energies focus on distinct erogenous zones.

protective methods of reducing anxiety by unconsciously distorting reality.
13. Repression (p.557): In psychoanalytic theory, the basic defense
mechanism that banishes anxiety-arousing thoughts, feelings, and
memories from consciousness.
14. Regression (p.557): Psychoanalytic defense mechanism in which an
individual faced with anxiety retreats to a more infantile psychosexual
stage, where some psychic energy remains fixated.
15. Reaction Formation (p.557): Psychoanalytic defense mechanism by
which the ego unconsciously switches unacceptable impulses into their
opposites. Thus, people may express feelings that are the opposite of
their anxiety-arousing unconscious feelings.
16. Projection (p.557): Psychoanalytic defense mechanism by which people
disguise their own threatening impulses by attributing them to others.
17. Rationalization (p.557): Defense mechanism that offers self-justifying
explanations in place of the real, more threatening, unconscious reasons
for one’s actions.
18. Displacement (p.558): Psychoanalytic defense mechanism that shifts
sexual or aggressive impulses toward a more acceptable or less
threatening object or person, as when redirecting anger toward a safer
19. Denial (p.558): Defense mechanism by which people refuse to believe or

people’s inner feelings by analyzing their interpretations of the blots.
24. Terror-Management Theory (p.562): A theory of death-related anxiety;
explores people’s emotional and behavioral responses to reminders of
their impending death.
25. Self-Actualization (p. 564): According to Maslow, one of the ultimate
psychological needs that arises after basic physical and psychological
needs are met and self-esteem is achieved; the motivation to fulfill one’s
26. Unconditional Positive Regard (p.564): According to Rogers, an attitude
of total acceptance toward another person.
27. Self-Concept (p. 566): All our thoughts and feelings about ourselves, in
answer to the question, “Who am I?”

gauge a wide range of feelings and behaviors; used to assess selected
30. Minnesota Multiphasic Personality Inventory (MMPI) (p.570): The mos
