The theory that the retina contains three different color receptors-one most sensitive to red, one to green, one to blue- which can produce the perception of any color. Ex: The theory that our retina picks up more reds, greens, and blues with the color receptor cones. Start studying AP Psychology: Chapter 5 Sensation.The Utility of Signal Detection Theory. Signal detection theory (SDT) is a technique that can be used to evaluate sensitivity in decision-making. Initially developed by radar researchers in the early 1950s ( Peterson et al., 1954 ), the value of SDT was quickly recognized by cognitive scientists and adapted for application in human decision ...Module 16 Flip It Video - Signal Detection Theory ...

Signal Detection Theory (SDT) is a rigorous framework used to quantify the ability to discern between information-bearing patterns, known as signals, and random patterns that distract from the signal, known as noise. Developed in the 1950s, SDT originated in the field of sensory psychology and was later applied to a multitude of disciplines ... Signal Detection Theory is a psychophysical model that explains how humans make decisions based on sensory information. It is based on the idea that individuals may pick up on meaningful information, known as “signals,” from noisy and ambiguous stimuli.Here, I trace both the origins of signal detection theory and the profound influence it has had on psychology and related fields. My analysis of its origins concentrates on three key developments. The first development was by Gustav Fechner (1860/1966), who conceived of signal detection theory for the two-alternative forced-choice (2AFC) task.Signal Detection Theory revolutionizes the understanding of sensory perception by considering the decision-making processes involved in detecting stimuli under uncertainty. This theory acknowledges that perception is not just about sensory input but also involves cognitive factors like expectations and motivations. It emphasizes the role of response …www.psychexamreview.com In this video I explain how signal detection theory relates to psychophysics and the study of absolute and difference thresholds. I ...

B. Signal-detection theory: theory which suggests how individuals are able to detect a minimal stimulus (signal) among other background stimuli (noise). This may influence how individuals make a decision in a specific situation. C. Receptor sensitivity is subject to change. 1. Sensory adaptation: a decline in receptor activity when stimuliABSTRACT.
