很少有研究比较图片交换通信系统 (PECS) 和用作语音生成设备 (SGD) 的 iPad 的功效，而且没有一项研究针对学龄前儿童。本研究比较了 PECS 和 iPad/SGD 对居住在马耳他的三名患有自闭症谱系障碍和功能性言语受限的学龄前儿童的相对功效。该研究采用了嵌入多基线设计中的适应性交替治疗设计，以强化剂的要求作为因变量。结果的视觉分析表明，所有参与者都需要针对 iPad/SGD 条件进行更多提示试验和会议。所有参与者都在 iPad 上学习了三步导航序列。参与者偏好调查没有结论，并且与获取请求技能的速度无关。结果表明，PECS 和 iPad 都适合教授初级沟通者所需的技能。
Few studies have compared the efficacy of the Picture Exchange Communication System (PECS) and iPads used as speech generating devices (SGDs), and none have targeted preschoolers. This study compares the relative efficacy of PECS and an iPad/SGD with three preschool-aged children with autism spectrum disorder and limited functional speech who lived in Malta. The study utilized an adapted alternating treatment design embedded in a multiple baseline design, with requesting of reinforcers as the dependent variable. Visual analysis of the results indicated that all participants required more prompted trials and sessions for the iPad/SGD condition. All participants learned a three step navigational sequence on the iPad. Participant preference probes were inconclusive and were not linked to speed of acquisition of requesting skills. Results suggest that both PECS and an iPad could be appropriate for teaching requesting skills to beginning communicators.
