Dual task experiments have highlighted that driving while having a conversation on a cell phone can have negative impacts on driving (Strayer & Drews, 2007). It has also been noted that this negative impact is greater when reading a text-message (Lee, 2007). Commonly used in text-messaging are shortening devices collectively known as text-speak (e.g.,Ys I wll ttyl 2nite, Yes I will talk to you later tonight). To the authors' knowledge, there has been no investigation into the potential negative impacts of reading text-speak on concurrent performance on other tasks. Forty participants read a correctly spelled story and a story presented in text-speak while concurrently monitoring for a vibration around their waist. Slower reaction times and fewer correct vibration detections occurred while reading text-speak than while reading a correctly spelled story. The results suggest that reading text-speak imposes greater cognitive load than reading correctly spelled text. These findings suggest that the negative impact of text messaging on driving may be compounded by the messages being in text-speak, instead of orthographically correct text.
双重任务实验已经表明，边开车边用手机交谈会对驾驶产生负面影响（斯特雷耶&德鲁斯，2007年）。也有人指出，阅读短信时这种负面影响更大（李，2007年）。短信中常用的缩写方式统称为短信体（例如，Ys I wll ttyl 2nite，即Yes I will talk to you later tonight，意为“是的，我今晚会再和你聊”）。据作者所知，尚未有人研究阅读短信体对同时进行的其他任务表现的潜在负面影响。40名参与者在同时监测腰部周围的震动时，阅读了一个拼写正确的故事和一个用短信体呈现的故事。与阅读拼写正确的故事相比，阅读短信体时反应时间更慢，检测到的正确震动次数更少。结果表明，阅读短信体比阅读拼写正确的文本带来更大的认知负荷。这些发现表明，短信体形式的短信而非拼写正确的文本，可能会加剧短信对驾驶的负面影响。
