In the simple reaction time task, you need to wait until you see a black cross on the white square. When that happens, you press as soon as you can the space bar. Thus, there is one stimulus (black cross) and one response (pressing the space bar). In the choice reaction time task, you need to wait until you see a black cross on one of the four ...

PDF Reaction Times and Hypothesis Testing
Calculate reaction time in seconds as before. A computer-based test of reaction times appear below. Go to the web site and follow the instructions. Method 4: This is a 'choice reaction time test' which tests how fast you can respond to the random appearance of dots in a grid over the course of 30 seconds.
Choice Reaction Time and Learning
"Reaction time. n.The time elapsed between the onset of a stimulus and a response to it… Simple reaction time applies when there is only one possible stimulus requiring only one type of response; choice reaction time (CRT) when there are two or more possible stimuli requiring different responses" (Coleman 2001).. Choice reaction time (CRT) tasks are widely used to explore the ...
Simple Reaction Time
In simple reaction time experiments, participants respond as quickly as possible anytime a stimulus appears. Simple reaction time is, in essence, a "baseline" measure of how quickly a person responds when no other mental processing (e.g., discrimination, response type) is required. ... The American Journal of Psychology, 123, 39-50. Sternberg ...

6 Two-Choice Reaction Times: Basic Ideas and Data
For a discussion of this and the effective use of random foreperiod in a choice experiment to suppress anticipatory responses, see Green, Smith, and von Gierke . And as we shall see in Section 6.6.5, considerable evidence exists that anticipations may be a problem in many choice-reaction time experiments.
Reaction Time: The Measure of an Emerging Paradigm
The Status of CRT in 1979. Choice reaction time has become a ubiquitous dependent variable rather than a topic area. This is possible because of the well-developed theoretical framework that researchers have established for the CRT task. Reaction-time measures are now used in all areas of cognitive psychology.
PsyToolkit: A novel web-based method for running online questionnaires
This article reviews PsyToolkit, a free web-based service designed for setting up, running, and analyzing online questionnaires and reaction-time (RT) experiments. It comes with extensive documentation, videos, lessons, and libraries of free-to-use psychological scales and RT experiments. It provides an elaborate interactive environment to use (or modify) the existing questionnaires and ...
Online psychophysics: reaction time effects in cognitive experiments
Experiment 2: reaction time task. The RT task was always conducted after the initial performance task and preceded the other five experiments. The intention of this task was to detect potential differences in RTs between the settings (lab, web-in-lab, web) at a very crude level and without high cognitive load.
Reaction-Time Experiments in Wundt's Institute and Beyond
Kurt Danziger (1980d) observed, "The reaction-time studies conducted during the first few years of Wundt's laboratory constitute the first historical example of a coherent research program, explicitly directed toward psychological issues and involving a number of interlocking studies" (p. 106). Wilhelm Wundt argued that these experiments ...
PDF A Literature Review on Reaction Time
time, the sequence of stimuli types is random. The Reaction Time program does not use this type of experiment because the response is always pressing the spacebar. Serial reaction time is a variant of choice reaction time in which the order of stimulus types is not random. Instead, a stimulus of type y is likely to follow a stimulus of type x.
Faster, smarter? Reaction times: raking around in cognitive psychology
In 1933, Beck reviewed over 30 studies examining the associations between reaction times and psychometric intelligence and found that 14 studies using simple or discriminative reaction time had a median correlation of −0.16 (range 0.32 to −0.90), 14 studies of serial reaction time showed a median correlation of −0.18 (range 0.03 to −0. ...
Stroop Effect Experiment in Psychology
The dependent variable (DV) was reaction time (ms) in reporting the letter color. Findings. After running the three experiments, Stroop drew two main conclusions: The interference of conflicting word stimuli upon the time for naming colors caused an increase of 47.0 seconds or 74.3 percent of the normal time for naming colors printed in just ...
A Comparative Study on Visual Choice Reaction Time for Different Colors
In recognition reaction time experiments, there are some stimuli (the "memory set") that should be responded to and others (the "distracter set") that should not be responded to. In choice reaction time experiments, ... The American Journal of Psychology. 1926; 37:414-417. doi: 10.2307/1413629. [Google Scholar] 10.
Donders Response Types
Donders Response Types. In 1868, the Dutch physiologist and ophthalmologist F. C. Donders suggested that such mental processes as sensory discrimination, perceptual identification, and motor selection might occur serially, each consuming a certain amount of time. If so, wrote Donders, "interposing into the process some new components of ...
Memory-Scanning: Mental Processes Revealed by Reaction-Time Experiments
In D. A. Balota & E. J. Marsh (Eds.), Cognitive psychology: Key readings (pp. 48-74). Psychology Press. Abstract. I will review informally eight experiments on the retrieval of information from human memory, whose interpretation depended on inferences from the structure of reaction time (RT) data to the organization of mental processes.
