Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

45.1K
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...

Self-Presentation01:25

Self-Presentation

383
Self-presentation is a fundamental aspect of social interaction, shaping both how others perceive individuals and how they view themselves. This dynamic process influences behaviors in various social settings, often leading people to adjust their appearance, speech, and demeanor to align with their desired identity. While self-presentation can be deliberate or unconscious, it plays a critical role in interpersonal relationships and self-perception.Forms of Self-PresentationSelf-presentation can...

Facial Feedback Hypothesis

851
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Motivational Bias01:25

Motivational Bias

473
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...

Self-Serving Bias01:29

Self-Serving Bias

318
Self-serving bias is a cognitive phenomenon in which individuals attribute positive outcomes to internal factors such as their abilities, intelligence, or effort while attributing negative outcomes to external circumstances. This cognitive distortion helps maintain self-esteem but can also impede objective self-assessment.Theoretical Explanations of Self-Serving BiasTwo primary theories explain the self-serving bias: the cognitive explanation and the motivational explanation.The cognitive...

Strategies of Self-Presentation III: Self-Monitoring

387
Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...

Summary

Selfie posing orientation is not determined by handedness or the hand used to take the photo. Participants predominantly presented their midline, not a specific cheek, regardless of motor biases.

Area of Science:

  • Psychology
  • Human-Computer Interaction
  • Biomechanical Psychology

Background:

  • Portrait photography often reveals a left-cheek bias in posing.
  • This left-cheek bias is also observed in selfies, informal smartphone self-portraits.
  • Previous theories suggested mechanical biases, like hand dominance, influence selfie posing orientation.

Purpose of the Study:

  • To investigate whether motor biases, specifically handedness and hand used for selfie capture, influence selfie posing orientation.
  • To test the hypothesis that mechanical biases predict selfie cheek preference.

Main Methods:

  • 320 participants (159 female, 161 male) were instructed to "pose as you really are" for a selfie.
  • Participants completed a handedness questionnaire.
  • The hand used to capture the selfie and the resulting pose orientation (left cheek, right cheek, or midline) were recorded.

Main Results:

  • Neither participant handedness nor the hand used to take the selfie predicted selfie pose orientation.
  • Participants were most likely to present a midline pose (49.75%), followed by right (26.72%) and left (26.53%) cheek poses.
  • Handedness strongly predicted the hand used for selfie capture (left-handers used their left, right-handers used their right), but not the posing orientation.

Conclusions:

  • Selfie cheek biases are not a direct result of the mechanics of taking selfies or motor biases.
  • The observed posing orientation in selfies is independent of handedness and the specific hand used to operate the smartphone.
  • Further research may explore other factors influencing selfie posing preferences beyond motor control.
