Key Concepts & Definitions

  • Sensory receptors: Peripheral sensory structures responsible for detecting stimuli from the environment, initiating the perceptive process. (implied in the source as part of the sensory input system).

  • Central nervous structures: Neural pathways and brain areas involved in processing sensory information, integrating signals, and forming perceptions. (implied as part of the integration process).

  • Learned discrimination: The ability to differentiate between stimuli based on prior experience, allowing for recognition and identification of objects. (described as discrimination, recognition, and identification in the source).

  • Recognition: The mental process of identifying an object or stimulus as familiar, based on stored knowledge and previous learning. (part of the discrimination and identification process).

  • Identification of objects: Assigning a specific name and function to a recognized object, facilitated by social and cultural learning. (final step in perceiving objects).
