Guaranteed – A+ Graded
Section A: Cognitive Development & Information Processing
Q1: A 4-year-old child insists that a tall, thin glass contains more juice than a short, wide
glass, even when both contain the same amount. According to Piaget, this
demonstrates:
A. Object permanence
B. Conservation failure [CORRECT]
C. Formal operational reasoning
D. Hypothetical-deductive thinking
Correct Answer: B
Rationale: Conservation is the understanding that quantity remains constant despite
changes in appearance; preoperational children (ages 2-7) fail conservation tasks due
to centration. Object permanence (Option A) develops in sensorimotor stage. Options C
and D describe formal operational stage abilities.
Q2: A teacher provides a student with temporary support to help them solve a math
problem they cannot yet solve independently. When the student masters the problem,
the support is gradually removed. This describes:
,A. Assimilation
B. Accommodation
C. Scaffolding [CORRECT]
D. Equilibration
Correct Answer: C
Rationale: Scaffolding (Vygotsky) is temporary support from a More Knowledgeable
Other (MKO) within the Zone of Proximal Development (ZPD), faded as competence
develops. Assimilation (Option A) and accommodation (Option B) are Piagetian
processes of incorporating new information. Equilibration (Option D) is Piaget's
balance-restoring process.
Q3: According to information processing theory, which memory store has the largest
capacity but the shortest duration?
A. Working memory
B. Long-term memory
C. Sensory memory [CORRECT]
D. Semantic memory
Correct Answer: C
Rationale: Sensory memory has a very large capacity (iconic memory holds all visual
information briefly) but decays within milliseconds to seconds. Working memory
(Option A) has limited capacity (7±2 items). Long-term memory (Option B) has
,potentially unlimited capacity and duration. Semantic memory (Option D) is a type of
long-term memory.
Q4: A student groups the words "cat, dog, bird, fish" into the category "animals" to
remember them more easily. This strategy is called:
A. Rehearsal
B. Chunking [CORRECT]
C. Elaboration
D. Maintenance rehearsal
Correct Answer: B
Rationale: Chunking organizes individual items into meaningful groups to overcome
working memory capacity limitations. Rehearsal (Options A and D) involves repetition.
Elaboration (Option C) connects new information to existing knowledge.
Q5: A teacher designs a lesson with minimal extraneous information and focuses
student attention on essential content. This practice aligns with:
A. Increasing intrinsic cognitive load
B. Reducing extraneous cognitive load [CORRECT]
C. Eliminating germane cognitive load
D. Maximizing working memory capacity
Correct Answer: B
, Rationale: Cognitive load theory (Sweller) identifies extraneous load as unnecessary
processing demands; good instruction minimizes extraneous load while managing
intrinsic load and promoting germane load. Option A increases difficulty. Option C is
counterproductive—germane load supports learning. Option D is not directly
controllable.
Q6: A student who can automatically recall multiplication facts without conscious effort
has developed:
A. Rote memorization only
B. Automaticity [CORRECT]
C. Metacognition
D. Transfer
Correct Answer: B
Rationale: Automaticity is the fluent, unconscious execution of well-practiced skills,
freeing working memory for higher-order processing. Rote memorization (Option A) may
not be automatic. Metacognition (Option C) is thinking about thinking. Transfer (Option
D) is applying learning to new contexts.
Q7: According to Piaget, a child in the concrete operational stage (ages 7-11) can:
A. Think abstractly and hypothetically
B. Perform mental operations on concrete objects but struggles with abstract concepts
[CORRECT]
C. Only think egocentrically
