Schemas

12.0K
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.

Impact of Schemas

7
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Altered States of Awareness01:06

Altered States of Awareness

540
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

1.0K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Summary
This summary is machine-generated.

Scaffolded attention creates visual patterns without sensory cues. Individual differences in this phenomenon are linked to attentional breadth, not mental imagery vividness.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Visual Perception

Background:

  • Percepts typically rely on sensory cues for structure.
  • Scaffolded attention generates visual structure in the absence of sensory input, termed 'everyday hallucinations'.
  • This phenomenon is inconsistently experienced across individuals, varying from spontaneous to non-existent.

Purpose of the Study:

  • To assess the prevalence of scaffolded attention, both spontaneously and as an ability.
  • To investigate the relationship between scaffolded attention and individual differences in imagery and attention.
  • To explore the underlying mechanisms of scaffolded attention, potentially involving perceptual grouping.

Main Methods:

  • Surveyed participants on spontaneous and instructed experiences of scaffolded attention.
  • Administered measures of mental imagery (vividness, spontaneity).
  • Assessed various aspects of attention, including attentional breadth (functional field of view).

Main Results:

  • 40% of participants experienced scaffolded attention spontaneously.
  • 78% experienced scaffolded attention when instructed.
  • Attentional breadth significantly modulated scaffolded attention experiences, while imagery measures did not.

Conclusions:

  • Scaffolded attention is a common perceptual phenomenon influenced by attentional factors.
  • Individual variations in scaffolded attention are better explained by attentional breadth than mental imagery.
  • Findings suggest scaffolded attention may arise from spontaneous perceptual grouping mechanisms.
