Prior studies have showed that presentation methods could affect the accuracy of a choice assessment.
In the current study, high- and low-preferred work tasks were identified in nine adults with developmental disabilities. Both tasks were then introduced in pairs within a choice assessment using the actual tasks, pictures of the tasks and spoken descriptions of the tasks. Participants were also given the Assessment of Basic Learning Abilities (ABLA) test that evaluated their discrimination skills.
For five of the participants, their consistent choice of preferred task was predicted by their discrimination skills as assessed by the ABLA.
These findings extend that of Conyers et al. whereby the systematic assessment of discrimination skills could predict the effectiveness of different presentation methods in this population.
先前的研究表明,呈现方式可能会影响选择评估的准确性。
在本研究中,在9名发育障碍成年人中确定了高偏好和低偏好的工作任务。然后在选择评估中,通过实际任务、任务图片和任务的口头描述将这两项任务成对呈现。参与者还接受了基础学习能力评估(ABLA)测试,以评估他们的辨别技能。
对于5名参与者,他们对偏好任务的一致选择可由ABLA评估的辨别技能预测。
这些发现扩展了康耶斯等人的研究结果,即对辨别技能的系统评估可以预测不同呈现方式在该人群中的有效性。
