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

Self-Presentation: Self-Monitoring and Self-Handicapping

43.5K
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

291
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...

Strategies of Self-Presentation I: Strategic Self-Presentation

202
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...

Processes of Self-Presentation

212
Effective self-presentation is a central component of social interaction and identity construction. It relies on the dynamic processes of defining the situation and engaging in self-disclosure. These mechanisms help individuals navigate social context expectations and manage how others perceive them, fostering mutual understanding and relationship development.Defining the SituationSocial situations are shaped by collectively understood frames—a set of widely understood rules or...

Strategies of Self-Presentation II: Self-Verification

175
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...

Classification of Neurotransmitters

5.1K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Area of Science:

  • Oncology
  • Nuclear Medicine
  • Endocrinology

Background:

  • Neuroendocrine tumors (NETs) are a diverse group of neoplasms originating from various organs.
  • NETs frequently manifest with distinct clinical syndromes caused by hormone hypersecretion.

Purpose of the Study:

  • To outline the diagnostic and therapeutic approaches for neuroendocrine tumors.
  • To emphasize the role of molecular-genetic work-up and advanced imaging in NET management.

Main Methods:

  • Utilizing hormone diagnostics and molecular-genetic analysis for NET diagnosis.
  • Employing morphological imaging (ultrasound, endoscopy, CT, MRI) and functional imaging (PET-CT, SPECT/CT) for NET visualization.
  • Leveraging somatostatin analogs, both native and radionuclide-coupled, for NET treatment.

Main Results:

  • Molecular-genetic work-up complements hormone diagnostics in NET evaluation.
  • Functional imaging techniques like Ga-68-DOTATATE-PET-CT and F-18-DOPA-PET/CT are crucial for NET imaging.
  • Somatostatin analogs represent effective therapeutic agents for various NETs.

Conclusions:

  • Imaging requirements for NETs are dictated by clinical presentation, laboratory results, tumor stage, and tumor syndromes.
  • Personalized systemic treatment modalities are essential for effective NET management.
