Step 1: Understanding the concept.
- Neo-determinism was introduced by Griffith Taylor.
- It is also known as 'Stop and go determinism'.
Step 2: Meaning of 'Stop and go determinism'.
- According to this concept, human activities are neither completely determined by the environment (as in environmental determinism) nor entirely independent (as in possibilism).
- Instead, human beings can progress within the limits set by the environment.
- The environment acts like a traffic signal — sometimes it allows, sometimes it restricts human actions.
Step 3: Elimination of wrong options.
- (B) Possibilism → Emphasizes human freedom, not stop-and-go restrictions.
- (C) Environmental determinism → Says environment completely controls humans, not partially.
- (D) Positivism → Relates to scientific method, not human-environment relation.
