___ is a response pattern in reaction to a stimulus in the environment. (a) Behaviour (b) Treatment (c) Effection (d) None ✅ Correct Option: (a) Behaviour Explanation: Behavior is defined as any observable response or action of an organism to external or internal stimuli. It can be voluntary (writing, speaking) or involuntary (reflex, emotional response). Psychology studies behavior as a primary indicator of mental processes, allowing researchers to infer thoughts, feelings, and learning. Treatments or “effection” are not defined in this context; behavior remains the core observable aspect for educational, clinical, and experimental psychology. Understanding behavior is crucial for analyzing student responses, therapy outcomes, or applied psychology interventions, making this a frequent PPSC exam topic. 10 PPSC-Relevant Facts: 1.
