Self-Presentation: Self-Monitoring and Self-Handicapping

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...

Reason and Intuition

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...

Self-Report Tests of Personality

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Summary

This summary is machine-generated.

Individuals with alcohol dependence exhibit greater impulsivity, consistently making risky choices on the Iowa Gambling Task compared to controls. This suggests impulsivity contributes to excessive drinking behaviors.

Context:

Impulsivity is a complex trait with significant implications for addiction.
Understanding impulsivity's role is crucial for addiction treatment and prevention.
Previous research links impulsivity to various substance use disorders.

Purpose:

To investigate impulsivity differences between individuals with alcohol dependence and controls.
To assess decision-making styles using the Iowa Gambling Task.
To explore the relationship between impulsivity and alcohol dependence.

Summary:

The study compared alcohol-dependent individuals (N=20) with a control group (N=21) using three impulsivity measures.
Alcohol-dependent subjects showed significantly poorer performance on the Iowa Gambling Task.
They consistently chose immediate rewards despite long-term negative consequences, indicating higher impulsivity.

Impact:

Findings highlight impaired decision-making as a key factor in alcohol dependence.
Results align with studies on drug abuse, suggesting common impulsivity mechanisms.
This research can inform interventions targeting decision-making deficits in excessive drinking.
