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).
1. How does recognition differ from identification within the perceptive function components?
2. Which of the following best describes a key feature of hyperesthesia in quantitative perception changes?
3. What do non-hallucinatory perceptions primarily refer to?
Perceptive Function Components — elements?
Sensory receptors, central structures, learned discrimination, recognition, identification, mental representations.
Quantitative perception changes — example?
Hyperesthesia, hypoesthesia, dulling, or intensification.
Non-Hallucinatory Perceptions — characteristics?
Accurate, faithful perceptions of real objects or true mental images.
Illusions — definition?
Deformation of perception of a real object.
Hallucinations — types?
Psychosensory (sensory qualities) and psychic (mental images).
Psychosensory hallucinations — example?
Auditory voices, visual scenes, tactile sensations.
