jelérzékelési
Jelérzékelés, often translated as signal detection, is a framework used to understand how people detect signals embedded in noise. It is a fundamental concept in psychology and neuroscience, with applications in fields ranging from audiology to artificial intelligence. The core idea is that detecting a stimulus is not simply a matter of whether the stimulus is present or absent, but rather a decision-making process influenced by both the strength of the stimulus and the observer's response criteria.
The signal detection theory models the process as a comparison between a sensory response and a decision
Key outcomes in signal detection tasks include correct rejections (correctly identifying when no signal is present),
