The theory maintains that as time horizons shrink, as they typically do with age, people become increasingly selective, investing greater resources in emotionally...
, in social psychology - Reactivity–selectivity principleReactivity–selectivity principleIn chemistry the reactivity–selectivity principle or RSP states that a more reactive chemical compound or reactive intermediate is less selective in chemical reactions. In this context selectivity represents the ratio of reaction rates....
, in chemistry - StereoselectivityStereoselectivityIn chemistry, stereoselectivity is the property of a chemical reaction in which a single reactant forms an unequal mixture of stereoisomers during the non-stereospecific creation of a new stereocenter or during the non-stereospecific transformation of a pre-existing one...
, in organic chemistry - Natural selectionNatural selectionNatural selection is the nonrandom process by which biologic traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution....
, in biology - Sensitivity and specificitySensitivity and specificitySensitivity and specificity are statistical measures of the performance of a binary classification test, also known in statistics as classification function. Sensitivity measures the proportion of actual positives which are correctly identified as such Sensitivity and specificity are statistical...
, in statistical theory - DiscriminationDiscriminationDiscrimination is the prejudicial treatment of an individual based on their membership in a certain group or category.
