Perceptual Constancy01:12

Perceptual Constancy

1.6K
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Gestalt Principles of Perception01:21

Gestalt Principles of Perception

1.4K
Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...

Visual System01:26

Visual System

1.9K
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

1.3K
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...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.1K
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.

Modeling and Similitude01:12

Modeling and Similitude

658
Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...

Summary

We introduce Coherencer, a new model for generating coherent visual imagination. Coherencer produces more coherent scene descriptions than existing models, improving cognitive generation.

Area of Science:

  • Cognitive Science
  • Computational Linguistics
  • Artificial Intelligence

Background:

  • Visual imagination can be incoherent when disparate concepts are combined.
  • Existing models struggle to generate contextually coherent visualizations.

Purpose of the Study:

  • To introduce and implement Coherencer, a novel computational model for contextual coherence in visual imagination.
  • To evaluate Coherencer's performance against established models.

Main Methods:

  • Developed the Coherencer model based on the SOILIE model of imagination.
  • Compared Coherencer's scene descriptions with SOILIE and a parallel connectionist algorithm.
  • Assessed the impact of association representations (co-occurrence probabilities vs. holographic vectors).

Main Results:

  • Coherencer generated significantly more coherent scene descriptions than SOILIE and a competitive connectionist algorithm.
  • Co-occurrence probabilities proved superior to holographic vectors as an association representation.
  • Improved coherence models enhance output quality irrespective of association type.

Conclusions:

  • Coherencer offers a cognitively plausible approach to concept combination in visual imagination.
  • The model aligns with theories of perceptual symbol systems and coherence.
  • Evidence suggests the process of achieving visualization coherence is serial and consistent with hippocampal function.
