The foreperiod (FP) is the interval between a warning stimulus and the imperative stimulus. It is a classical finding that both the duration and the intertrial variability of FP considerably affects response time.
What is the purpose of the Foreperiod?
What is Foreperiod duration?
One of the oldest and most robust findings in the field of cognitive psychology is the fact that the length of the foreperiod (FP)—the temporal interval that precedes the presentation of an imperative stimulus—can influence severely one’s reaction time (RT) to that stimulus.
What is the meaning of reaction time?
Reaction time may be defined simply as the time between a stimulus and a response.
What is the compatibility effect?
It occurs when there is a harmonious relation between what you observe and how you have to respond to it. The figure below shows a daily life example of a compatible and incompatible situation. If you are right handed, a cup handle on the right side of a cup is compatible.
What is choice reaction time?
the total time that elapses between the presentation of a stimulus and the occurrence of a response in a task that requires a participant to make one of several different responses depending on which one of several different stimuli is presented.
What is reaction time used for?
In cognitive psychology, reaction time (RT) is used to measure the amount of time that it takes an individual to process information (Luce). It is the duration of the interval between presentation of a stimulus (e.g., a word on a computer monitor) and the participant’s response to the stimulus.
How is compatibility defined for displays and controls?
Control/Display Compatibility – Compatibility refers to the relationship of stimuli and responses to human expectations.
What is movement compatibility?
Movement compatibility refers to the relationship between control motions and the movement of display indicators. When people interact with a control and display system, they will normally have certain expectations about the relationship between the movement of the controls and the movement of the display indicators.
