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...

Bullying

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

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.

Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Surveys

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Summary

Reinforcement sensitivity is lower in online interactions compared to offline ones. This difference, particularly in individuals with Internet addiction, highlights how online engagement impacts reward and aversion sensitivity, potentially maintaining addiction.

Area of Science:

Psychology
Neuroscience
Digital Media Studies

Background:

Reinforcement sensitivity theory (RST) posits distinct systems for reward and aversion.
Online environments may differentially engage these sensitivity systems compared to offline interactions.
Understanding these differences is crucial for addressing behavioral patterns in digital spaces.

Purpose of the Study:

To compare reinforcement sensitivity between online and offline interactions.
To investigate the influence of gender, Internet addiction, and depression on these differences.
To explore the role of online gaming in modifying reinforcement sensitivity.

Main Methods:

A large cohort of 2,258 college students (1,066 males, 1,192 females) participated.
The Behavior Inhibition Scale (BIS) and Behavior Approach Scale (BAS) were administered for both online and offline contexts.
Measures of Internet addiction, depression, and online activity type were collected concurrently.

Main Results:

Reinforcement sensitivity scores were significantly lower during online interactions than offline.
Students with Internet addiction exhibited smaller decreases in BIS/BAS scores post-online engagement.
Elevated reward and aversion sensitivity correlated with a higher risk of developing Internet addiction.

Conclusions:

Online engagement appears to modulate an individual's reinforcement sensitivity.
The pursuit of online rewards may play a role in the persistence of Internet addiction.
Changes in reinforcement sensitivity associated with online activity are implicated in the risk and maintenance of Internet addiction.
