This study considers comprehension of the Scottish police caution amongst people with an intellectual disability (n = 30). It applies techniques to the caution that are suggested to increase its ‘listenability’, to examine whether this could be a successful method of improving understanding. These techniques include providing instructions, further explanations and listing information. Half of the participants were assessed using the original version and half the modified version. Participants were assessed using an abbreviated IQ assessment, a measure of working memory and measure of state anxiety to consider potential predictors of performance. The modified version did not improve performance, with no participants judged to have adequate understanding in either version.

本研究考虑了智障人士（n  = 30）对苏格兰警方警告的理解。它将技巧应用于建议增加其“可听性”的警告，以检查这是否可以成为提高理解的成功方法。这些技术包括提供说明、进一步的解释和列表信息。一半的参与者使用原始版本和一半的修改版本进行评估。参与者使用简短的 IQ 评估、工作记忆的测量和状态焦虑的测量进行评估，以考虑潜在的表现预测因素。修改后的版本没有提高性能，没有参与者认为对任一版本有足够的理解。
