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.

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...

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Summary

Understanding impulsivity requires clear definitions. This study links self-reported impulsivity and time perception, suggesting cognitive tempo influences impulsive behaviors.

Area of Science:

Psychology
Cognitive Neuroscience

Background:

Impulsivity research faces challenges due to inconsistent definitions and measurement methods.
A clear understanding of impulsivity's underlying mechanisms is crucial.

Purpose of the Study:

To investigate the relationship between self-reported impulsivity, behavioral control, and time perception.
To explore potential cognitive mechanisms underlying impulsive behavior.

Main Methods:

Assessed self-reported impulsivity using the Adaptive and Maladaptive Impulsivity Scale (AMIS).
Measured behavioral inhibitory and excitatory processes via the Stop Signal Task.
Evaluated time perception using the retrospective Time Estimation Task.

Main Results:

Self-reported impulsivity (AMIS) and behavioral control (Stop Signal Task) showed no direct relationship.
Time perception was significantly correlated with both measures.
Longer perceived time intervals correlated with higher AMIS Disinhibition scores and faster Stop Signal Task responses.

Conclusions:

Findings suggest cognitive tempo, related to how individuals perceive time, may be a key mechanism in impulsive behavior.
Highlights the importance of considering temporal perception in understanding and measuring impulsivity.
