See the resources page of IU's Second Language Psycholinguistics Lab for several how-to tutorials. While the DMDX program itself is no longer in actively development, it is still very popular, and new information is occasionally posted to the updates page and help pages. Scripts are written in a special scripting language inside a Rich Text Format (RTF) file, which DMDX parses to run the experiment. This can be done relatively easily by adapting the templates provided in the detailed ExperimentMFC documentation in the Praat manual.ĭMDX (DisplayMaster DirectX) is a software program designed for measuring reaction times to visual and auditory stimuli. The popular phonetics software program Praat has the capability to run Multiple Forced-Choice (MFC) listening experiments (i.e., the subject is presented with several options and must choose one of them).Ī wide variety of functionality is supported, such as carrier phrases, goodness judgments, replay buttons, and stimulus-dependent text prompts.Įxperiments are built this way by creating a script file using a special scripting language within Praat specially for this purpose. Since this makes it possible to build an experiment without writing any Python code by hand, this is a viable option even for people with little to no programming background.įor more information on PsychoPy, see its entry under Scripting in Python below. While PsychoPy is based on the Python language, it also has a point-and-click interface (known as 'Builder'). This makes it possible to look at the dynamics of how participants' hand movements settle into a response alternative (and how they may be partially pulled toward other alternatives), yielding valuable information about real-time cognitive processing. Once recorded, mouse trajectories can be visualized, averaged, and explored, and measures of attraction/curvature, complexity, velocity, and acceleration can be computed. MouseTracker allows you to record a participant's hand movements traveling toward response alternatives on the computer screen via the coordinates of the computer mouse. In addition, scripts can be written in the underlying scripting language in order to add custom functionality. The standard components of a psychology experiment – groups, blocks, trials, and factors – are all represented graphically, and experiments are constructed by working with these elements in interactive windows and dialogs. PsyScope X is a graphical user interface (GUI) software program that allows researchers to design and run experiments without the need for programming. OpenSesame can both play back soundfiles stored on your computer as well as synthesize sounds on the spot. This allows you to build complex experiments with minimum effort. OpenSesame is a graphical experiment builder, providing a modern point-and-click user interface for creating experiments. ProRec saves a 'prompts time' text file along with the recorded audio file, thus indexing the individual tokens in the recording (thus potentially saving post-processing time, especially if automated by a script). a word or a sentence) to the participant for them to read out loud and records their speech back to disk from a microphone. ProRec ('Prompt & Record') presents timed visual text prompts (e.g. Calligra Stage (Part of the Calligra office suite).The program 'Impress' that comes bundled with Apache OpenOffice, LibreOffice, and NeoOffice.Of course, given its limited capabilities, presentation software is only suitable for very basic experiments. The lowest-tech option is to simply treat the experiment like a presentation for a class or a conference.įor a production experiment, you can display the word(s) the participant should read in large font in the center of each slide.įor a perception experiment, you can add a soundfile to each slide that play as soon as the slide is displayed, and have the participant type a response or move objects to indicate their response. Operating system: All major operating systems (depending on the program).
