Social Foundations of Self IV: Self in Digital Communication01:30

Social Foundations of Self IV: Self in Digital Communication

139
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

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...

Self-Presentation01:25

Self-Presentation

229
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...

Impression Management Techniques I: Managing Appearances

158
Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...

Strategies of Self-Presentation II: Self-Verification

134
Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

Strategies of Self-Presentation I: Strategic Self-Presentation

160
Strategic self-presentation refers to individuals' intentional efforts to influence how others perceive them. This process is employed in various social and professional settings, such as job interviews, dating, politics, and legal contexts, where individuals seek to shape impressions to gain social or material advantages. While people generally present themselves in ways that align with their authentic characteristics, external factors, such as cognitive load, can hinder their ability to...

    Area of Science:

    • Computer Vision
    • Image Processing
    • Artificial Intelligence

    Background:

    • Smartphone photography often suffers from harsh, unflattering lighting due to built-in flashes.
    • Achieving studio-quality lighting typically requires specialized equipment and controlled environments.

    Purpose of the Study:

    • To develop an algorithm capable of converting smartphone flash selfies into images with uniform, studio-like lighting.
    • To mitigate common lighting artifacts caused by direct camera flash illumination.

    Main Methods:

    • The CNN was trained on paired datasets: smartphone flash images and corresponding studio-lit images of the same subjects.
    • The algorithm learns to map the characteristics of flash photography to studio lighting conditions.

    Main Results:

    • The algorithm successfully transforms images taken with smartphone flashes into photographs with uniform lighting.
    • It effectively corrects artifacts such as specular highlights, harsh shadows, and excessive skin shine.
    • The output resembles professional studio portraiture.

    Conclusions:

    • This novel algorithm offers a practical solution for improving smartphone selfie quality.
    • It democratizes studio-quality portrait lighting, making it accessible via mobile devices.
