HDFS 210 EXAM 1 ACTUAL EXAM QUESTIONS AND ANSWERS PRACTICE QUESTIONS
WITH SOLUTIONS NEWEST | ALREADY GRADED A+
Question 1
In a study of the behavioral adjustment of a group of children placed in foster care, the children
were assessed once a year over a period of 10 years. This is an example of a ________ study.
A) Developmental
B) Cross-sectional
C) Longitudinal
D) Sequential
E) Experimental
Correct Answer: C) Longitudinal
Rationale: Longitudinal research follows the same individuals over a long period of time to
observe how they change. This allows researchers to see the direct development of a specific
cohort rather than comparing different people of different ages.
Question 2
Infants are exposed to massive amounts of information; they must focus their attention and select
information so as not to be overwhelmed. Thus, children must __________ selectively.
A) Retrieve
B) Encode
C) Automate
D) Store
E) Adapt
Correct Answer: B) Encode
Rationale: Encoding is the process by which information is initially recorded in a form
usable to memory. Selective encoding allows the infant to focus on specific stimuli while
filtering out irrelevant data.
Question 3
Which term refers to an infant's various levels of wakeful behaviors, such as alertness, fussing,
and crying, and different levels of sleep?
A) Sensitive period
B) Rhythm
C) Alternation
D) State
E) Habituation
Correct Answer: D) State
Rationale: "State" refers to the degree of awareness an infant displays to both internal and
external stimulation. It includes levels of deep sleep, active sleep, quiet alertness, and
crying.
Question 4
Which of the following is considered a biological universal event that occurs at relatively the
, 2
same time throughout all societies?
A) Graduation
B) Marriage
C) Puberty
D) Retirement
E) Driver's licensing
Correct Answer: C) Puberty
Rationale: Puberty is a normative age-graded influence. It is a biological process that
happens to all humans around the same developmental window, regardless of their specific
culture or society.
Question 5
Who is considered the predominant theorist in the field of cognitive development?
A) Jean Piaget
B) Sigmund Freud
C) B.F. Skinner
D) Albert Bandura
E) Erik Erikson
Correct Answer: A) Jean Piaget
Rationale: Jean Piaget is famous for his theory of cognitive stages, suggesting that children's
thinking changes qualitatively as they grow. He viewed children as "active scientists"
exploring their world.
Question 6
Piaget's theory assumed that all children pass through a series of universal stages in fixed order.
These four stages are:
A) Sensorimotor, preoperational, concrete operational, and formal operational
B) Oral, anal, phallic, latency, and genital
C) Trust, autonomy, initiative, and industry
D) Microsystem, mesosystem, exosystem, and macrosystem
E) Infancy, toddlerhood, childhood, and adolescence
Correct Answer: A) Sensorimotor, preoperational, concrete operational, and formal
operational
Rationale: These four stages represent the progression from reflexive, physical interaction
with the world (sensorimotor) to abstract, hypothetical reasoning (formal operational).
Question 7
An infant who learns that smiling at his or her parents brings positive attention and therefore
begins to smile more often is demonstrating what type of learning?
A) Habituation
B) Classical conditioning
, 3
C) Modeling
D) Operant conditioning
E) Social referencing
Correct Answer: D) Operant conditioning
Rationale: Operant conditioning is learning in which a voluntary response is strengthened
or weakened, depending on its association with positive or negative consequences (rewards
or punishments).
Question 8
An observable trait—a trait that is actually seen or expressed—is labeled as a:
A) Dominant
B) Phenotype
C) Recessive
D) Genotype
E) Chromosome
Correct Answer: B) phenotype
Rationale: While the genotype is the underlying genetic combination of an individual (the
"blueprint"), the phenotype is the actual physical or behavioral expression of those genes.
Question 9
Baby Polly is usually happy, but when taken to a family reunion, her face crinkles in a frown and
she stares at unfamiliar people with suspicion. This is an example of:
A) Stranger anxiety
B) Separation anxiety
C) Nonverbal encoding
D) Disorganized attachment
E) Avoidant behavior
Correct Answer: A) stranger anxiety
Rationale: Stranger anxiety typically appears around 6 months of age and represents the
caution and wariness displayed by infants when encountering an unfamiliar person.
Question 10
What is the term for a developing child from 8 weeks after conception until birth?
A) Embryo
B) Fetus
C) Zygote
D) Blastocyst
E) Neonate
Correct Answer: B) fetus
Rationale: The prenatal period is divided into the Germinal (0-2 weeks), Embryonic (2-8
