Mertens –Teaching Assistant Spring 2021 11:00–12:15 Tuesday, Thursday 4/16 1.Jan.2021 Signal Detection Theory: In the 1950s a major theoretical advance was made by combining detection theory with statistical decision theory.Psychologists use signal detection theory to evaluate how accurately participants are able to recognize faint stimuli under a variety of different conditions. In a typical experiment the participants are asked to indicate if the stimulus was either present or absent, and the researcher assesses if the decision was correct.Signal detection theory predicts when an individual will decide if a weak stimulus is present or not based on psychological factors as opposed to the biological theories of absolute threshold. Psychologists use signal detection theory to evaluate how accurately participants are able toSignal detection theory provides a precise lan-guage and graphic notation for analyzing decision making in the presence of uncertainty. Simple Forced Choice I begin here with the classic example of detecting brief, dim flashes of light in a dark room. Imagine that we use a simple forced-choice method in which the light is flashed

Green the classic work published in this area in 1966 (reprinted in 1974 and 1988).

Cornea: The transparent, protective outer layer of the eye that bends light waves to assist in proper focus.Sensation - How we detect physical energy from the environment and encode it as neural signals. Perception - Process of organizing and interpreting sensory info. Transduction - Conversion of one form of energy to another form. There are 3 steps every time you convert sensory energy to get the info to your brain.

The theory ...
