neuroscience research. It makes it easy to synthesize and show accurately controlled visual and auditory stimuli and interact with Psychtoolbox interfaces between Matlab or Octave and the computer hardware. The PTB core routines provide access to the display frame buffer and color lookup table, reliably synchronize with the vertical screen retrace, support sub-millisecond timing, expose raw OpenGL commands, support video playback and capture as well as low-latency audio, and facilitate the collection of observer responses. Ancillary routines support common needs like color space transformations and the QUEST threshold seeking algorithm. Psychophysics Toolbox Version 2 with its Matlab C extensions rewritten to be more modular and to use OpenGL on the back end. The current version supports Matlab R2012a+ and Octave 3.8 and later on Linux, and Octave 4.4.1 on MacOSX, and Windows. Psychtoolbox 3.0.15 Beta update “Late Bloomer” was released at 25th November 2018. As usual, the complete development history can be The Psychtoolbox-3.0.15 beta update “Late Bloomer”, apart from minor improvements, adds one piece of long awaited functionality, basic support for the Oculus VR Rift CV1 Virtual Reality headset for 64-Bit Microsoft Windows 7 and later. Two years later than i hoped, PsychOculusVR1() driver allows use of the Oculus Rift CV1 under 64-Bit Microsoft-Windows 7 or later versions with Octave 4.4.1 or Matlab. Use of Windows-10 is strongly recommended. Existing VR usercode should not need modifications if it uses the PsychVRHMD() high-level driver, as the new driver is as compatible to the old driver as possible, so the switch to a Rift CV1 should be basically plug & play. Example demos that should work are VRHMDDemo, VRHMDDemo1, SuperShapeDemo, MorphDemo, and as part of the separate Horde3DForPsychtoolbox package the HordeVRDemo. Clas*ic “closed loop” VR with a tight stimulus presentation loop that uses Screen(‘Flip’, win); should work well,
