CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

151
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Timing and Consequences on Behavior

In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Summary
This summary is machine-generated.

Daily alcohol expectancies influence drinking behavior through social context, subjective effects, and craving. Positive expectancies can increase drinking, while relaxation expectancies may decrease it, highlighting self-fulfilling prophecies.

Area of Science:

  • Psychology
  • Addiction Research
  • Behavioral Science

Background:

  • Alcohol expectancies are established risk factors for problem drinking.
  • Mechanisms linking daily expectancy fluctuations to acute drinking behavior remain understudied.

Purpose of the Study:

  • To investigate the sequential mediation of social context, subjective responses, and craving in the relationship between daily expectancy deviations and drinking behavior.
  • To examine how different types of alcohol expectancies (rewarding, relaxation, aggression) influence drinking patterns.

Main Methods:

  • A 21-day ecological momentary assessment study with 131 participants reporting binge, social, and solitary drinking.
  • Multilevel models analyzed the predictive relationships between daytime expectancies, social context, subjective responses (valence/arousal), craving, and within-session drinking.

Main Results:

  • Increased daytime expectancies predicted experiencing expected effects during drinking.
  • Rewarding expectancies predicted social drinking and heavier consumption via enhanced rewarding effects and craving.
  • Relaxation expectancies were associated with reduced drinking, while aggression expectancies predicted increased drinking via aggressive effects and craving.

Conclusions:

  • Daily alcohol expectancies act as self-fulfilling prophecies, predicting context-specific drinking and subjective experiences.
  • Interventions targeting daytime expectancy fluctuations and promoting protective strategies may be beneficial for managing alcohol consumption.
