互联网可以成为帮助有学习障碍的人获取相关且适当的书面信息的绝佳工具。然而，几乎没有开展任何工作来确定该群体的网页设计或内容偏好。本文研究了解决这个问题的方法。二十五名参与者看到了三个处理就业信息的网站。他们被要求浏览每一个并执行一系列设定的任务。访谈和评级量表确定了偏好。通过避免“两极疑问句”（需要“是/否”或类似两极分化的答案的问题），默许偏见问题（人们倾向于自动同意那些处于权威地位的人的倾向）被最小化。参与者喜欢使用图片，尤其是当它们以其他有学习障碍的年轻人为主角时。与金钱或利益相关的抽象内容常常被忽视。尽管没有广泛使用，但提供音频的地方受到赞赏。还建立了有关文本大小和菜单位置的偏好。将结果与其他相关文献和建议进行比较，以帮助网络开发人员和信息提供商。本研究固有的方法论问题是评级系统的使用和访谈技术。早期发现，三分制的中立立场令人困惑，因此对前者进行了调整。使用四个点可以避免这个问题并产生更多不同的结果。避免极端疑问极大地有助于最大限度地减少“默许偏见”。该研究的结论是，可以从那些难以表达自己观点的人那里获取大量信息。
The Internet can be an excellent tool to help people with learning disabilities access relevant and appropriately written information. However, little work has been undertaken to ascertain web design or content preferences for this cohort. This paper examines methods to address this issue. Twenty five participants were presented with three web sites dealing with employment information. They were asked to browse each and carry out a series of set‐tasks. Interviews and a rating scale ascertained preferences. The problem of acquiescence bias, the tendency for people to automatically agree with those in perceived positions of authority, was minimised by the avoidance of ‘polar interrogatives’ (questions requiring a ‘yes/no’ or similarly polarised answer).Participants liked the use of pictures, especially when they featured other young people with learning disabilities. Abstract content related to money or benefits often went unnoticed. Audio was appreciated where offered, although not extensively used. Preferences regarding text size and menu position were also established. Results are compared to other relevant literature and recommendations formulated to help web developers and information providers. The methodological issues inherent in this study were the use of the rating system, and the interview technique. The former was adapted following early findings that the neutral position, on a three point scale, was confusing. Using four points avoided this problem and produced more varied results. Avoiding polar interrogatives greatly helped in minimising ‘acquiescence bias’. The study concludes that it is possible to elicit considerable information from people who find it difficult to articulate their views.
