Summary
Alcohol-dependent individuals perceive intoxication cues related to internal feelings and external signs. These perceptions align with the internal-external dichotomy in blood alcohol level discrimination research.
Area of Science:
- Psychology
- Neuroscience
- Addiction Research
Background:
- Understanding self-perception of intoxication is crucial for alcohol dependence treatment.
- Previous research suggests an internal-external dichotomy in discriminating blood alcohol levels.
Purpose of the Study:
- To investigate how alcohol-dependent individuals categorize cues related to self-perceived intoxication.
- To determine if these perceived cues align with the internal-external dichotomy framework.
Main Methods:
- Twenty-eight alcohol-dependent participants rated the similarity of 18 intoxication-related cues.
- Cluster analysis was employed to group the perceived similarities of these cues.
Main Results:
- Participant ratings formed four distinct clusters: disinhibition, relaxation, impairment, and external cues.
- These identified clusters provide empirical support for the internal-external dichotomy model.
Conclusions:
- Alcohol-dependent individuals' perceptions of intoxication cues can be categorized into internal (disinhibition, relaxation, impairment) and external factors.
- The findings support the utility of the internal-external dichotomy in understanding self-judgment of intoxication in this population.

02:05Self-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...
01:38Cognitive Dissonance
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:27CNS 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...
01:25Factors Affecting Perception
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

01:06Altered States of Awareness
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

01:28Depressants
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
