Vision01:24

Vision

61.4K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Self-Awareness and Its Effects01:21

Self-Awareness and Its Effects

362
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.

Cognitivism

3.4K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

High-Level and Low-Level Awareness

897
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Visual System01:26

Visual System

2.3K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Visual Agnosia01:12

Visual Agnosia

1.7K
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Summary
This summary is machine-generated.

Misleading environments reduce willingness to attribute perception and knowledge, but do not cause denial. Causal modeling reveals knowledge attributions drive perception and assertability judgments, supporting knowledge as the norm of assertion.

Area of Science:

  • Cognitive Psychology
  • Epistemology
  • Linguistics

Background:

  • Philosophical debates exist on how misleading environments affect attributions of perception and knowledge.
  • Understanding the relationship between perception, knowledge, and assertion is crucial for folk epistemology.

Purpose of the Study:

  • To investigate the impact of misleading environments on judgments of perception, knowledge, and assertion.
  • To explore the causal relationships between explicit judgments of seeing, knowing, and asserting.
  • To test whether misleading environments lead to denial of perception and knowledge.

Main Methods:

  • Two experiments were conducted to examine explicit judgments under varying environmental conditions.
  • Causal modeling was employed to determine the directional influence between perception, knowledge, and assertability attributions.

Main Results:

  • A visually misleading environment decreased willingness to attribute perception and knowledge.
  • No evidence was found for denial of perception or knowledge in misleading environments.
  • Causal modeling indicated a specific order: knowledge attributions influence perception attributions, which then influence assertability attributions.

Conclusions:

  • Misleading environments intuitively reduce attributions of perception and knowledge, aligning with some philosophical claims.
  • Stronger philosophical claims suggesting denial of perception and knowledge in such environments were not supported.
  • A psychological model suggests knowledge is the norm of assertion, with knowledge attributions preceding perception and assertability attributions.
