Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
For example, IEEE P802.3ap Task Force uses measured S-parameters as test cases [11] for proposed solutions to the problem of 10 Gbit/s Ethernet over backplanes. Accurate noise modeling is a must. Create a list of expected noise events, including different types of noise, such as coupling and charge sharing.
In modern psychology, vigilance, also termed sustained concentration, is defined as the ability to maintain concentrated attention over prolonged periods of time. [1] During this time, the person attempts to detect the appearance of a particular target stimulus. The individual watches for a signal stimulus that may occur at an unknown time. [2]
Reality testing is the psychotherapeutic function by which the objective or real world and one's relationship to it are reflected on and evaluated by the observer. This process of distinguishing the internal world of thoughts and feelings from the external world is a technique commonly used in psychoanalysis and behavior therapy, and was originally devised by Sigmund Freud.
Human performance modeling (HPM) is a method of quantifying human behavior, cognition, and processes.It is a tool used by human factors researchers and practitioners for both the analysis of human function and for the development of systems designed for optimal user experience and interaction . [1]
The human brain receives millions of arrays of signals in different modalities, all through the waking periods. These signals are classified and stored in terms of their relationship perceived as function of experience and available knowledge base of an individual, as well as new relationship produced through sequential processing.
The signal is typically measured most strongly by the electrodes covering the parietal lobe. The presence, magnitude, topography and timing of this signal are often used as metrics of cognitive function in decision-making processes. While the neural substrates of this ERP component still remain hazy, the reproducibility and ubiquity of this ...
The Gudjonsson suggestibility scale (GSS) was created in 1983 by Icelandic psychologist Gísli Hannes Guðjónsson.Given his large number of publications on suggestibility, Gísli was often called as an expert witness in court cases where the suggestibility of those involved in the case was crucial to the proceedings.
