What are the short-term psychological effects of barbiturates?

1. Memory enhancement and increased focus

2. Reduction of tension and anxiety

3. Heightened alertness and motivation

4. Increased energy and euphoria

The correct answer is: Reduction of tension and anxiety

Barbiturates are central nervous system depressants that are primarily used for their sedative and anxiolytic effects. One of the primary short-term psychological effects of barbiturates is the reduction of tension and anxiety. These substances work by enhancing the action of the neurotransmitter gamma-aminobutyric acid (GABA), which leads to a calming effect on the brain. This can result in decreased feelings of stress and anxiety, making the individual feel more relaxed. In contrast, the other options describe effects that are not typically associated with barbiturate use. Memory enhancement and increased focus are more commonly associated with stimulants rather than depressants. Heightened alertness and motivation also align with stimulant effects, while increased energy and euphoria are typically linked to drugs that have stimulant properties. Therefore, the calming and anxiety-reducing effects of barbiturates accurately represent their short-term psychological impact.
