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 ...
Serial reaction time (SRT) is a commonly used parameter in the measurement of unconscious learning processes. [1] This parameter is operationalised through a SRT task, in which participants are asked to repeatedly respond to a fixed set of stimuli in which each cue signals that a particular response (i.e., button press) needs to be made.
Hick's law. Hick's law, or the Hick–Hyman law, named after British and American psychologists William Edmund Hick and Ray Hyman, describes the time it takes for a person to make a decision as a result of the possible choices: increasing the number of choices will increase the decision time logarithmically. The Hick–Hyman law assesses ...
The stimulus–response model is a conceptual framework in psychology that describes how individuals respond to external stimuli. According to this model, an external stimulus triggers a reaction in an organism, often without the need for conscious thought. This model emphasizes the mechanistic aspects of behavior, suggesting that behavior can ...
Psychological refractory period. The term psychological refractory period (PRP) refers to the period of time during which the response to a second stimulus is significantly slowed because a first stimulus is still being processed. [1] This delay in response time when one is required to divide attention can exhibit a negative effect that is ...
Stimulus onset asynchrony. Stimulus-onset asynchrony (SOA) is a measure used in experimental psychology. SOA denotes the amount of time between the start of one stimulus, S1, and the start of another stimulus, S2 (Figure 1). In this respect, a stimulus may consist of, e.g., a presented image, sound or printed word.
Personal equation. The term personal equation, in 19th- and early 20th-century science, referred to the idea that different observers have different reaction times, which can introduce bias when it comes to measurements and observations. [1]
measure aggressive behavior. The Taylor Aggression Paradigm (TAP; also commonly referred to as the Competitive Reaction Time Task[1]) is a prominent, well-validated, laboratory analog measure of aggressive behavior in humans, predominantly utilized within the field of psychology.
