Self-Schemas02:16

Self-Schemas

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
The Looking Glass Self01:28

The Looking Glass Self

The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical self-perception,...
Self-Awareness and Its Effects01:21

Self-Awareness and Its Effects

Self-awareness is a psychological state in which the individual becomes the focal point of their attention. This inward focus transforms the self into an object of contemplation and assessment, influencing how individuals perceive their actions and their alignment with personal and societal standards.Triggers and Contexts for Self-AwarenessSelf-awareness can be activated by external stimuli that make individuals visually or audibly aware of themselves, such as mirrors, cameras, or recordings.
Understanding the Self01:28

Understanding the Self

The self is a central aspect of human identity, encompassing an individual’s beliefs, emotions, perceptions, and experiences. It is a cognitive and psychological construct that enables individuals to interpret their traits and behaviors, influencing how they perceive themselves and interact with the world. While personality consists of stable and enduring characteristics, the self is shaped by self-perception and social experiences. This distinction highlights the dynamic nature of the self,...
Understanding Self-Concept01:20

Understanding Self-Concept

The self-concept encompasses individuals' beliefs about themselves, structured through cognitive frameworks known as self-schemas. These schemas function as mental representations of specific traits or behaviors, influencing how self-relevant information is perceived, processed, and remembered. For example, individuals who are schematic for body weight are more likely to interpret routine experiences—such as dining out or shopping—through the lens of that trait. Conversely, those aschematic for...
The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Summary
This summary is machine-generated.

The visual system can detect its own internal noise, using this information to adjust perception thresholds for tasks like orientation judgments. This self-monitoring mechanism may be a fundamental aspect of how we perceive the world.

Area of Science:

  • Neuroscience
  • Perception Science
  • Computational Vision

Background:

  • Biological visual systems, like all information processors, are susceptible to internal and external noise.
  • This noise typically does not directly affect conscious perception.

Purpose of the Study:

  • To investigate whether the visual system has access to its own internal noise levels.
  • To determine if this self-knowledge of noise influences perceptual thresholds.

Main Methods:

  • The study focused on orientation judgment tasks.
  • Analysis of how the visual system responds to varying levels of internal and external noise.

Main Results:

  • Evidence suggests the visual system monitors its own noisiness.
  • Perceptual thresholds are adjusted based on the system's estimated noise levels.

Conclusions:

  • The visual system possesses a mechanism to gauge its own noise.
  • This self-monitoring capability is crucial for accurate perception and may be a general principle across sensory modalities.
