Question: Julian and his friends enjoy taking weekend road trips. Julian takes the lead
on mapping the travel, navigating traffic, and deciding how best to navigate hiking
trails. According to Gardner, Julian demonstrates signs of which type of intelligence?
A) Logical-mathematical
B) Spatial
C) Intrapersonal
D) Linguistic
Correct Answer: B Spatial
Expert Rationale: Spatial intelligence involves the ability to perceive, understand, and
navigate visual and spatial information. Julian's skills in mapping routes, reading traffic
patterns, and navigating trails all require strong spatial awareness. Understanding
Gardner's multiple intelligences is essential because it recognizes diverse cognitive
strengths beyond traditional academic abilities.
Question: Gender, the sense of being male or female, is well established by the time
children are:
A) Around 8 years old
B) Adolescents
C) Preschool age
D) Infants
Correct Answer: C Preschool age
Expert Rationale: Gender identity is typically well established by preschool age (3-5
years). Understanding this is essential because children develop a stable sense of gender
,identity during early childhood. By preschool, children can consistently label their own
gender and recognize gender categories in others.
Question: Meredith is a 17-year-old adolescent who weighs approximately 82 pounds
and is gaunt and frail with a skeletal appearance. Whenever she looks at herself in the
mirror, she thinks she is disgustingly fat. Meredith is suffering from:
A) Bulimia
B) Malnutrition
C) Obesity
D) Anorexia nervosa
Correct Answer: D Anorexia nervosa
Expert Rationale: Anorexia nervosa is characterized by extreme weight loss, a distorted
body image, and an intense fear of gaining weight. Meredith's severely low weight, skeletal
appearance, and perception of herself as "disgustingly fat" despite being emaciated are
classic signs. Understanding this is essential because anorexia has the highest mortality
rate of any psychiatric disorder.
Question: What is Vygotsky's term for the level at which a child can almost, but not
quite, understand or perform a task?
A) Theory of mind
B) Metamemory
C) Zone of proximal development
D) Transference
Correct Answer: C Zone of proximal development
Expert Rationale: The Zone of Proximal Development (ZPD) is the gap between what a
child can do independently and what they can achieve with guidance. Understanding this is
essential because Vygotsky emphasized that learning occurs through social interaction
within the ZPD. Scaffolding provides support within this zone.
Question: What is one significant reason for the advances in fine motor skills in
children 6-8 years old?
, A) Amount of myelin in the brain increases to protect, insulate, and surround nerve cells
B) Children live long enough to get more practice with fine motor skills
C) Children's cognitive development is increasing
D) Children have more opportunity to model fine motor skill behaviors
Correct Answer: A Amount of myelin in the brain increases to protect, insulate, and
surround nerve cells
Expert Rationale: Myelination increases the speed of neural transmission, enhancing fine
motor coordination. Understanding this is essential because brain development underlies
motor skill improvement. The increased myelination during middle childhood allows for
more precise and controlled movements.
Question: Compared to less popular children, popular children are more likely to:
A) Read others' nonverbal behavior and understand others' emotional experiences
B) Disregard others' emotional experiences
C) Control their own nonverbal behavior less effectively
D) Demonstrate a lack of humor
Correct Answer: A Read others' nonverbal behavior and understand others' emotional
experiences
Expert Rationale: Popular children tend to have stronger social cognitive skills, including
the ability to read nonverbal cues and understand others' emotions. Understanding this is
essential because social competence contributes to peer acceptance. Empathy and
emotional intelligence are key factors in popularity.
Question: For a child to remember a piece of information, how many processes must
function properly?
A) Four
B) Three
C) Six
D) Five
Correct Answer: B Three
Expert Rationale: Memory involves three processes: encoding (information enters
memory), storage (information is retained), and retrieval (information is accessed).
