The (Spatial) Memory Game: Testing the Relationship Between Spatial Language, Object Knowledge, and Spatial Cognition

11.3K
We present a protocol to explore the relationship between spatial language production, spatial memory, and object knowledge. The procedure allows experimental manipulation of, and control over, conditions of object knowledge, language at instruction, and physical location, thus teasing apart cognitive and linguistic models describing interactions between these...

Creating Objects and Object Categories for Studying Perception and Perceptual Learning

12.2K
We describe a novel methodology for creating naturalistic 3-D objects and object categories with precisely defined feature variations. We use simulations of the biological processes of morphogenesis and phylogenesis to create novel, naturalistic virtual 3-D objects and object categories that can then be rendered as visual images or haptic...

The study of how damage to the brain affects cognitive functioning has historically been one of the most important tools for cognitive neuroscience. While the brain is one of the most well protected parts of the body, there are many events that can affect the functioning of the brain. Vascular issues, tumors, degenerative diseases, infections, blunt force traumas, and neurosurgery are just some...

This article describes RUGGED (Retrieval Under Graph-Guided Explainable disease Distinction), which integrates Large Language Model (LLM) inference with Retrieval-Augmented Generation (RAG). It draws evidence from expert-curated biomedical knowledge bases and peer-reviewed biomedical publications to synthesize new knowledge from up-to-date information, identify explainable and actionable predictions, and pinpoint promising directions for hypothesis-driven...

Perspectives on Sensation and Perception

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University
The study of sensation—how signals are transduced from sensory organs, like the eyes—and perception—how the brain interprets these messages—has a rich history dating back to the 19th century, when great strides were made in understanding the properties of light and how they relate to the visual system. Importantly, such sensory and perceptual processes determine what we see, feel, taste, and hear in...

Summary

A stroke patient (RDS) with impaired color naming could still perceive colors and name objects. His deficit stemmed from difficulty linking object shapes with colors, impacting conceptual color knowledge.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Linguistics

Background:

  • Investigating object-color knowledge in patients with brain damage is crucial for understanding visual processing.
  • A specific case study, RDS, presented with impaired color naming following a left occipito-temporal stroke.

Observation:

  • RDS exhibited preserved color perception, object naming, and verbal knowledge of typical object colors.
  • He could identify appropriate object colors but struggled to match color names to objects or color patches to grayscale objects.

Findings:

  • The patient's color-naming deficit was linked to an impaired conceptual relationship between visually presented object shapes and colors.
  • Results suggest holistic processing of objects with their typical colors in the visual modality.
  • Color naming abilities may play a role in abstracting colors from visual objects.

Implications:

  • Findings contribute to models of neuro-functional organization for object-color knowledge.
  • This research informs understanding of visual processing, color cognition, and language acquisition.
  • Highlights the interconnectedness of visual perception, conceptual knowledge, and linguistic abilities.
