States that circumstances, experiences, expectations affect our thresholds. subliminal perception.Signal detection theory is the ability to choose between and identify stimuli. Perceptual constancy refers to the tendency in humans to see familiar things as having similar shapes, colors, and sizes, in spite of changes that may have occurred in that object.
Abstract. In perceptual, cognitive, and diagnostic tasks, accuracy depends on both limited sensitivity and the application of a decision process. By making explicit assumptions about the nature of the cognitive representation, signal detection theory (SDT) measures the contributions of these two components of performance.
