Jaroszewski, K. A. (1999). Cognitive aspects of performance.
Traditionally, information processing has been studied through the use of reaction time (RT) tasks. RT tasks fall into two categories: simple and choice RT tasks. In simple RT tasks, participants are asked to make a single response to a single stimulus. In choice RT tasks, participants choose a correct response based on the stimulus that is presented. Participants thus have two or more ways of responding to two or more stimuli. By examining both the speed and accuracy with which responses are made, under varying conditions, inferences about the covert or underlying cognitive processes are made. This has enabled people to develop theories about the way information is processed and the rate at which it is processed.
____1) Typically, information processing has been examined through the use of reaction time (RT) tasks. There are two types of RT tasks, simple and choice RT tasks. Simple RT tasks, require subjects to make one response to a one picture. In choice RT tasks, subjects have at least two ways of responding to at least two pictures. Subjects must choose the correct response base on the picture that they see. When both speed and accuracy of responses are examined, conclusions about the underlying processes can be drawn. Researchers then develop theories about how fast and the way information is processed.
____2) According to Jaroszewski (1999) information processing has been examined through the use of reaction time (RT) tasks. There are two types of RT tasks, simple and choice RT tasks. Simple RT tasks, require subjects to make one response to one picture. In choice RT tasks, subjects have at least two ways of responding to at least two pictures.

Researchers then develop theories about how fast and the way information is processed.
____3) According to Jaroszewski (1999)both simple and choice reaction time (RT) tasks have been used to study information processing. The difference between a simple and a choice reaction time task is in the number of pictures and in the number of responses that can be made. With a simple RE task, only one picture is shown and one response can be made. With a choice RT task, there is at least 2 different pictures and at least 2 different ways to respond. Researchers use both speed and accuracy information to come up with theories about information processing (Jaroszewski, 1999).
____4) Theories about the way information is processed and the rate at which it is processes have traditionally been studied through reaction time tasks (Jaroszewski, 1999)
____5) By looking at how quickly and accurately people perform reaction time tasks, theories about information processing are developed (Jaroszewski, 1999).
____6) According to Jaroszewski (1999) when researchers combine both speed and accuracy information from reaction time studies, they can develop theories about underlying cognitive processes.
