According to Bloom's taxonomy which option is incorrect for the preparation of objective based questions?

Benjamin Bloom's taxonomy is a set of three hierarchical models that refers to the classification of educational learning objectives. In the taxonomy, Bloom identified three domains of learning which include cognitive, affective, and psychomotor.

These three domains have been divided in a way that proceeds from the simplest process to the complex.

• Cognitive domains: In this domain, a child deals with knowledge and hence, learns to create, evaluate, analyze, etc.
• Psychomotor domains: It is concerned with acquiring skills that require the integration of mental and physical movements.
• Affective domains: It includes how we deal with things emotionally, such as feelings, values, appreciation, etc.

The work of preparing questions is related to the 'cognitive domain' which involves mental skills that are categorized into six levels of learning that serve in the development of intellectual skills and acquisition power. 

The cognitive domains as per Bloom's taxonomy:

• Remember: Retrieving the relevant knowledge from long-term memory.
• Understand: Construct meaning from instructional messages, including oral, written, and graphic communication.
• Application: Carry out or use a procedure in a given situation.
• Analysis: Break material into its constituent parts and determine how the parts relate to one another and to an overall structure or purpose.
• Evaluation: Make judgments based on criteria or standards.
• Create: Put elements together to form a coherent or functional whole; reorganizing elements into a new pattern or structure.

Hence, it could be concluded that according to Bloom's taxonomy 'Self-actualization' is incorrect for the preparation of objective-based questions.
