Description. Free response questions require test takers to respond to a question or open-ended prompt with a prose response. In addition to being graded for factual correctness, free response questions may also be graded for persuasiveness, style, and demonstrated mastery of the subject material. Free response questions are a common part of ...
Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as " response time ") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive ...
The Stanford marshmallow experiment was a study on delayed gratification in 1970 led by psychologist Walter Mischel, a professor at Stanford University. [ 1] In this study, a child was offered a choice between one small but immediate reward, or two small rewards if they waited for a period of time. During this time, the researcher left the ...
Two-alternative forced choice. Two-alternative forced choice ( 2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input. For example, to determine a person's sensitivity to dim light, the ...
The neuroscience of free will, a part of neurophilosophy, is the study of topics related to free will ( volition and sense of agency) using neuroscience and the analysis of how findings from such studies may impact the free will debate . As medical and scientific technology has advanced, neuroscientists have become able to study the brains of ...
Eriksen flanker task. In cognitive psychology, the Eriksen flanker task is a set of response inhibition tests used to assess the ability to suppress responses that are inappropriate in a particular context. The target is flanked by non-target stimuli which correspond either to the same directional response as the target ( congruent flankers ...
Challenge-response protocols are also used to assert things other than knowledge of a secret value. CAPTCHAs, for example, are a variant on the Turing test, meant to determine whether a viewer of a Web or mobile application is a real person. In early CAPTCHAs, the challenge sent to the viewer was a distorted image of some text, and the viewer ...
In animals, including humans, the startle response is a largely unconscious defensive response to sudden or threatening stimuli, such as sudden noise or sharp movement, and is associated with negative affect. [1] Usually the onset of the startle response is a startle reflex reaction. The startle reflex is a brainstem reflectory reaction (reflex ...
