Answer: Whorf's Linguistic determinism hypothesis
Explanation: The concept of Whorf's Linguistic Determinism hypothesis argues that language or linguistic affiliation sets the tone or determines human knowledge, reasoning ability and perceptive capability. The stance maintained by Whorf's concept generally opines that cognitive processes in human are dictated and dependent on the linguistic affiliation and the level of human knowledge or intelligence could be traced to their language.
However, the scenario above seems to challenge Whorf's concept in the sense that both six years old ohmar and his 3 years old brother seem to have the same level of knowledge even though one will rarely find a six month old child who is able to speak a certain language with conviction. The scenario above directly counters Whorf's claim as the cognition level exhibited by both children is clearly not language dependent.
