Q1. A researcher studying the effects of sleep deprivation on cognitive function observes that participants exhibit impaired decision-making skills. Which of the following neurotransmitters is primarily responsible for this effect?
Answer: Acetylcholine
Explanation: Acetylcholine plays a crucial role in regulating attention and executive functions, which are impaired during sleep deprivation. Incorrect options: dopamine is involved in reward processing and motivation, not decision-making; serotonin is related to mood regulation, not cognitive function; norepinephrine is involved in arousal and stress responses, not decision-making.
