Arrange the cognitive processes in ascending order from earliest basic sensation to higher-level accommodation. 1. Accommodation 2. Perception 3. Scheme formation 4. Assimilation 5. Sensation

Introduction / Context:
This item checks understanding of a plausible progression of cognitive processes from raw input to advanced schema change. In educational psychology, we often move from sensation to perception, build mental schemes, assimilate new information, and finally accommodate by restructuring those schemes when assimilation is insufficient.

Given Data / Assumptions:

• Sensation = detection of stimuli.
• Perception = organization/interpretation of sensations.
• Scheme formation = building mental categories/templates.
• Assimilation = fitting new information into existing schemes.
• Accommodation = modifying schemes to fit new information.

Concept / Approach:
Order processes by dependency: perception depends on sensation; schemes must exist before they can assimilate; accommodation is a higher-order adjustment that changes the scheme itself.

Step-by-Step Solution:
Begin with 5 Sensation (raw input).Then 2 Perception (organized awareness).Next 3 Scheme formation (create cognitive structures).Then 4 Assimilation (integrate into schemes).Finally 1 Accommodation (revise schemes when needed).

Verification / Alternative check:
Accommodation cannot precede scheme formation; perception cannot precede sensation. The chain 5→2→3→4→1 respects increasing cognitive complexity.

Why Other Options Are Wrong:
Orders starting with accommodation or assimilation invert prerequisites; placing scheme formation after assimilation is illogical; mixing sensation late breaks the input→processing flow.

Common Pitfalls:
Equating assimilation with accommodation (they are distinct) and assuming either precedes scheme formation.

Final Answer:
5, 2, 3, 4, 1
