The PC can also run Psychophysics Toolbox but currently this software cannot utilize the response pads in the MSR. PsyScope X is set up on the Mac Mini but is rarely used. The experiment took place in a quiet room and participants wore noise-cancelling headphones (SONY, ZX110NC, Tokyo. We use this for both auditory and visual experiments. The experiment was designed and run using PsyScope program (Cohen et al., 1993). Zoom ‘ n ‘ scroll for precise inspecting, up to sample rez. Show individual or overlapped layers, from L, R, or mono sum. Features: 4x stereo inputs for multi channels checking. Stimuli are normally administered via Psychophysics Toolbox, which operates with MATLAB or, if from the PC, via Presentation or DMDX software. Psyscope free is a multi-track synced oscilloscope plugin inspired from Psylab build-in scope. It runs on Apple Macintosh computers and was originally designed for use with the Mac OS 9 platform. PsyScope on a personal computer (Macintosh G3) with a PsyScope button box (Cohen, MacWhinney, Flatt, & Provost, 1993).Theviewingdistancewas70cm,andacentral fixationcrossthatextendedacrossavisualangleof0.4°×0. The interface between the buttons and the computers is a 904 FIU series photodiode box. PsyScope is a graphical user interface (GUI) software program that allows researchers to design and run psychological experiments. The actual peripheral response buttons in the MSR are two 2-button response pads (a total of four buttons) utilizing a photodiode system that sends signals directly to the stimulus computer via a USB plug. the program psyscope, and get bactrim ds on line a fiber-optic key press interfaced with the psyscope button box to record subjects button press to the. Stimuli were generated by a Macintosh G3 computer using the psyscope software program and rear projected (Ampro Model LCD-150, Melbourne, FL) onto a projection screen positioned at the head end of the MRI scanner bore. Responses by the subject are triggered either by voice (See the OptoAcoustics system ) or button-press from a Current Designs (Philadelphia, PA) fiber optic system. collecting user requirements incorporating user feedback making improvements based on: human-computer interaction human factors research data validating functionality and usability. Both of these devices have millisecond resolution accuracy, and are not susceptible to the same drag that Mac and PC system “clocks” are. Ideally we want to use one of the above mentioned Button Boxes because the response is time stamped within Button Box and they provide the possibility to send an external TTL pulse in response to Matlab command. For PsyScope, all timing for experiments, along with all responses made during experiments, is managed by a Response Button Box developed by ioLab Systems. Resources at the LAE Labs Hardware PsyScope button box PST response box Video recording and playing devices Sound-attenuated booths for recording and. For the iMac and PC, stimuli triggering is run through a StimTracker Model ST-100 (Cedrus Corporation San Pedro, CA). We also have an Apple Mac Mini running PsyScope X software. Natick, MA), or from a PC running Presentation (Neurobehavioral Systems, Inc. At present, all of our experimental stimuli are administered from an Apple iMac computer utilizing Psychophysics Toolbox, which operates with MATLAB software (The MathWorks, Inc.
