Direct access to environmental stimuli and opportunity to ask for social contact/attention may be considered highly relevant objectives for persons with multiple disabilities. We assessed the possibility of enabling three of these persons (two children and one adolescent) to combine two microswitches (for accessing environmental stimuli) and a Voice Output Communication Aid (VOCA), which allowed them to ask for caregiver's attention.
Initially, the participants were required to use each of the two microswitches individually and then together. Thereafter, they were taught to use the VOCA. Eventually, the VOCA was available together with the microswitches, and the participants could use any of the three.
The results, which support preliminary data on this topic, showed that all participants (1) were able to operate the two microswitches as well as the VOCA; and (2) used all three of them consistently when they were simultaneously available.
Teaching persons with multiple disabilities to combine a VOCA with conventional microswitches may enrich their general input, emphasize their active social role and eventually enhance their social image.
对于多重残疾人士而言，直接接触环境刺激以及有机会寻求社会接触/关注可能被视为高度相关的目标。我们评估了让其中三名多重残疾人士（两名儿童和一名青少年）将两个微动开关（用于接触环境刺激）与语音输出沟通辅助设备（VOCA）相结合的可能性，该设备使他们能够寻求照顾者的关注。
最初，要求参与者分别单独使用两个微动开关，然后一起使用。此后，教导他们使用VOCA。最终，VOCA与微动开关一起可用，参与者可以使用这三者中的任何一个。
支持该主题初步数据的结果表明，所有参与者（1）能够操作两个微动开关以及VOCA；（2）当这三者同时可用时，他们持续使用所有这三个设备。
教导多重残疾人士将VOCA与传统微动开关相结合，可能会丰富他们的一般输入，强化他们积极的社会角色，并最终提升他们的社会形象。
