Craving and substance use: Examining psychophysiological and behavioral moderators

Summary
Craving predicts alcohol and drug use, but inhibitory control measures did not moderate illicit drug use as expected. Individual differences in post-error slowing influenced the craving-alcohol use relationship.
Area of Science:
- Neuroscience
- Psychology
- Addiction Research
Background:
- Substance use theories highlight craving and inhibitory control.
- The interplay between momentary craving and inhibitory control in predicting real-world drug use remains understudied.
Purpose of the Study:
- To investigate if individual differences in inhibitory control moderate the link between momentary craving and alcohol/drug use.
- To assess the consistency of inhibitory control measures (electrophysiology and behavior).
Main Methods:
- Current illicit drug users completed laboratory tasks (flanker, go/no-go) measuring inhibitory control via electroencephalography (EEG) and behavior.
- Two weeks of smartphone-based ambulatory assessments monitored craving and substance use.
Main Results:
- Momentary craving predicted subsequent alcohol and drug use.
- Traditional inhibitory control measures (e.g., P3 amplitude) did not moderate illicit drug use.
- Lower post-error slowing was associated with a stronger craving-alcohol use link.
Conclusions:
- Electrophysiological and behavioral measures of inhibitory control assess distinct cognitive processes.
- These distinct processes may differentially influence alcohol and drug use and craving dynamics.

Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.

01:24Substance Use Disorders Affecting Sleep
411
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.

One of the significant functions of connective tissue is connecting tissues and organs. Unlike epithelial tissue that is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. It plays a significant role in the functioning of this tissue. The major component of the matrix is a...

00:54What is Behavior?
10.2K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

01:28Behaviorism
4.7K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
