Negative correlation can be seen geometrically when two normalized random vectors are viewed as points on a sphere, and the correlation between them is the cosine of the arc of separation of the points on the sphere. [1] When this arc is more than a quarter-circle (θ > π/2), then the cosine is negative. Diametrically opposed points represent ...
The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. [6] The false positive rate depends on the significance level. The specificity of the test is equal to 1 minus the false positive rate.
If worth is a positive number, it is a positive relationship. On the contrary, a negative number indicates a negative relationship. The worth of a relationship influences its outcome, or whether people will continue with a relationship or terminate it. Positive relationships are expected to endure, whereas negative relationships will probably ...
Priming is a concept in psychology to describe how exposure to one stimulus may influence a response to a subsequent stimulus, without conscious guidance or intention. [1] [2] [3] The priming effect is the positive or negative effect of a rapidly presented stimulus (priming stimulus) on the processing of a second stimulus (target stimulus) that appears shortly after.
Politeness theory. Politeness theory, proposed by Penelope Brown and Stephen Levinson, centers on the notion of politeness, construed as efforts to redress the affronts to a person's self-esteems or face (as in "save face" or "lose face") in social interactions. [1][2][3][4][5][6][7][8] Notable concepts include positive and negative face, the ...
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
v. t. e. Affect, in psychology, is the underlying experience of feeling, emotion, attachment, or mood. [1] It encompasses a wide range of emotional states and can be positive (e.g., happiness, joy, excitement) or negative (e.g., sadness, anger, fear, disgust). Affect is a fundamental aspect of human experience and plays a central role in many ...
Reciprocity (social psychology) In social psychology, reciprocity is a social norm of responding to a positive action with another positive action, rewarding kind actions. As a social construct, reciprocity means that in response to friendly actions, people are frequently much nicer and much more cooperative than predicted by the self-interest ...
