1. Sensory Modalities

Key Concepts & Definitions

  • Sensory Modality: A specific type of sensory perception that corresponds to a particular sense, such as vision or hearing, involving specialized sensory receptors.
  • Receptors: Specialized nerve cells that detect specific types of stimuli (e.g., photoreceptors for light, mechanoreceptors for pressure).
  • Transduction: The process by which sensory receptors convert physical stimuli into neural signals that can be interpreted by the brain.
  • Sensory Thresholds: The minimum level of stimulus intensity required for detection (absolute threshold) or for noticeable difference (difference threshold or JND).
  • Perceptual Organization: The process of organizing sensory input into meaningful patterns, guided by principles like Gestalt laws.
  • Perceptual Constancy: The tendency to perceive objects as unchanging despite variations in sensory input (e.g., size, color).
