Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...
Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

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...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
Drug Dependence01:17

Drug Dependence

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

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 the way you...

Summary
This summary is machine-generated.

Implicit cognitions reliably predict substance use, with a moderate overall effect size. However, this relationship varies based on how implicit cognition is measured and the specific substance studied.

Area of Science:

  • Psychology
  • Neuroscience
  • Addiction Research

Background:

  • Implicit cognitions, or unconscious biases, may influence substance use behaviors.
  • Understanding these automatic associations is crucial for developing effective prevention and intervention strategies.

Purpose of the Study:

  • To quantify the overall relationship between substance-related implicit cognitions and substance use.
  • To explore factors that moderate this relationship, including measurement methods and substance type.

Main Methods:

  • A meta-analysis was performed, synthesizing data from 89 effect sizes.
  • Data included responses from 19,930 participants across various studies.
  • Analyses examined heterogeneity and moderation by methodological factors.

Main Results:

  • A significant positive association was found between implicit cognitions and substance use (r=.31).
  • Effect sizes varied significantly based on the facet of implicit cognition assessed, measurement strategy, sample characteristics, and substance type.
  • Largest effect sizes were observed for implicit semantic associations, word association measures, and marijuana use.

Conclusions:

  • Implicit cognition is a robust predictor of substance use.
  • Methodological factors significantly influence the observed effect sizes, highlighting the need for careful study design.
  • Further research should consider these moderators to refine our understanding of implicit processes in substance use.
