Recent interest in university teaching has focused on interactivity in lectures and practical classes, and teachers in several fields have set up systems in which students can interact with the lecturer using mobile-phone-based SMS text messaging. This approach has particular potential in psychology, where students could use SMS messaging as a way of responding in simple psychology experiments or demonstrations. We describe a simple architecture for an SMS-based responding, using an SMS-to-HTTP message relay service, and a PHP/MySQL input-output handler. We describe briefly two experiments we have run using the system. The first experiment examined anchoring effects in an SMS-based auction. The second experiment examined delay discounting, with participants indicating their intertemporal preferences using SMS. Finally, we evaluate the feedback we obtained from students about the practical and conceptual issues surrounding text-message-based responding.
最近对大学教学的关注集中在讲座和实践课程中的互动性上，多个领域的教师已经建立了系统，学生可以通过基于手机的短信文本消息与讲师进行互动。这种方法在心理学领域具有特殊潜力，学生可以使用短信作为在简单心理学实验或演示中做出反应的一种方式。我们描述了一种基于短信回复的简单架构，使用短信到HTTP消息中继服务以及PHP/MySQL输入输出处理程序。我们简要描述了使用该系统进行的两个实验。第一个实验在基于短信的拍卖中检验了锚定效应。第二个实验检验了延迟折扣，参与者通过短信表明他们的跨期偏好。最后，我们评估了从学生那里获得的关于基于文本消息回复的实际和概念性问题的反馈。
