For example, John Donne and the metaphysical poets developed the conceit as a literary device, where an elaborate, implausible, and surprising analogy was demonstrated. In Renaissance poetry, and particularly in sonnets, the contrast was similarly used as a poetic argument. In such verse, the entire poem argues that two seemingly alike or ...
For example, in the case of graphical computer displays, contrast depends on the properties of the picture source or file and the properties of the computer display, including its variable settings. For some screens the angle between the screen surface and the observer's line of sight is also important.
A contrast effect is the enhancement or diminishment, relative to normal, of perception, cognition or related performance as a result of successive (immediately previous) or simultaneous exposure to a stimulus of lesser or greater value in the same dimension. (Here, normal perception, cognition or performance is that which would be obtained in ...
In discourse theory, and computational discourse, contrast is a major discourse relation, on par with relationship like explanation or narration, and work has concentrated on trying to identify contrast in naturally produced texts, especially in cases where the contrast is not explicitly marked.
A contrast is defined as the sum of each group mean multiplied by a coefficient for each group (i.e., a signed number, c j). [10] In equation form, = ¯ + ¯ + + ¯ ¯, where L is the weighted sum of group means, the c j coefficients represent the assigned weights of the means (these must sum to 0 for orthogonal contrasts), and ¯ j represents the group means. [8]
The assimilation effect, assimilation bias or biased assimilation is a bias in evaluative judgments towards the position of a context stimulus, while contrast effects describe a negative correlation between a judgment and contextual information.
Behavioral contrast refers to a change in the strength of one response that occurs when the rate of reward of a second response, or of the first response under different conditions, is changed. For example, suppose that a pigeon in an operant chamber pecks a key for food reward.
In rhetoric, antithesis is a figure of speech involving the bringing out of a contrast in the ideas by an obvious contrast in the words, clauses, or sentences, within a parallel grammatical structure. [7] The term "antithesis" in rhetoric goes back to the 4th century BC, for example Aristotle, Rhetoric, 1410a, in which he gives a series of ...
