Definition
  1. Noun:
    • The property or quality of being selective: The characteristic of carefully choosing only certain things or people, or of responding only to specific stimuli.
    • The degree to which a device (like a radio receiver) can distinguish a desired signal from others: A measure of how well a system can select a specific frequency or signal while rejecting unwanted ones.
Usage Examples
  • General Use:
    • The selectivity of the admissions process ensures only the most qualified candidates are chosen.

  • Technical/Scientific Use:
    • This new filter offers improved selectivity, blocking unwanted noise effectively.
    • The radio's poor selectivity made it difficult to tune into just one station.
Advanced Usage
  • "Kinetic selectivity": In chemistry, refers to the preference of a reaction to produce one product over another based on reaction rates.
    • The catalyst demonstrated high kinetic selectivity for the desired isomer.
  • "Binding selectivity": In biochemistry, describes the degree to which a ligand binds to a particular target versus other potential targets.
    • The drug's effectiveness depends on its binding selectivity for the receptor.

  • Choosiness: The quality of being very careful in choosing (more informal).
  • Specificity: The quality of belonging or relating uniquely to a particular subject.
Related Phrases and Concepts
  • "Selectivity coefficient": In analytical chemistry, a numerical measure of an electrode's or sensor's preference for one ion over another.
  • "Frequency selectivity": In acoustics and signal processing, the ability of a system to resolve different frequency components.
