心理物理学和神经生理学研究需要精确控制实验设备，以提供刺激并监测行为和神经反应。这以前是通过复杂的、通常是专有的、可编程的系统来实现的，这些系统与有限范围的硬件接口。我们开发了一个完全在Matlab环境中的软件解决方案，可以实现实验和行为变量的高速控制。我们在GNU公共许可证下免费提供这个Wake-Forest Visual Experimentation（WaVE）软件，并演示如何根据个人实验室的需要对其进行定制。WAVE利用现有的Matlab库和工具箱来呈现视觉刺激，收集实验数据，更新行为变量，并与其他计算机进行通信。虽然我们已经开发了它在基于Windows的个人计算机中使用，Matlab代码的可移植性使其定制在各种其他系统中使用成为可能。我们目前的模拟结果显示亚毫秒级的采样率和更新精度，运行在单处理器，台式电脑。该软件提供了一个简单，灵活和强大的解决方案，与许多昂贵的替代品相比毫不逊色。(C)2004 Elsevier B.

Psychophysical and neurophysiological research requires precise control of experimental devices for the purpose of delivering stimuli and monitoring behavioral and neural responses. This has previously been accomplished by complex, often proprietary, programmable systems, interfacing with a limited range of hardware. We have developed a software solution entirely within the Matlab environment that can achieve high-speed control of experimental and behavioral variables. We make this Wake-Forest Visual Experimentation (WaVE) software freely available under the GNU public license, and demonstrate how to customize it to individual laboratory needs. WaVE takes advantage of existing Matlab libraries and toolboxes to present visual stimuli, collect experimental data, update behavioral variables, and communicate with other computers. Although we have developed it for use in a Windows-based Personal Computer, the portability of the Matlab code makes possible its customization for use in a variety of other systems. We present simulation results showing sub-millisecond sampling rate and updating precision, running on single-processor, desktop PCs. The WaVE software offers a simple, flexible and powerful solution that compares favorably with many of its costly alternatives. (C) 2004 Elsevier B.V. All rights reserved.
