The primary method of data analysis in applied behavior analysis is visual analysis. However, few investigations to date have taught the skills necessary for accurate visual analysis. The purpose of the present study was to evaluate computer-based training on the visual analysis skills of adults with no prior experience. Visual analysis was taught with interactive computer-based training that included written instructions and opportunities for practice with textual feedback. Generalization of participant skills from simulated to handwritten and authentic data graphs was programmed for and assessed during the study. A multiple-baseline design was used across visual analysis properties (i.e., variability, level, and trend), with continuous overall intervention effect generalization probes, replicated across 4 participants to evaluate computer-based training for accurate visual analysis of A-B graphs. The results showed that all participants accurately visually analyzed A-B graphs following the computer-based training for variability, level, trend, and overall intervention effect. These visual analysis skills generalized to handwritten and authentic data graphs and maintained approximately 1 day, 1 week, 2 weeks, and 1 month following mastery of each property for all participants. Implications of the results suggest that computer-based training improved accurate visual analysis skills for adults with no prior experience.
应用行为分析中的主要数据分析方法是视觉分析。然而，迄今为止，很少有研究教授进行准确视觉分析所需的技能。本研究的目的是评估针对没有相关经验的成年人进行的基于计算机的视觉分析技能培训。通过基于计算机的交互式培训来教授视觉分析，该培训包括书面指导以及提供带有文本反馈的练习机会。在研究过程中，对参与者的技能从模拟数据图推广到手写数据图和真实数据图的情况进行了规划和评估。采用多基线设计，涉及视觉分析的多个属性（即变异性、水平和趋势），并进行连续的总体干预效果推广探测，对4名参与者进行重复实验，以评估基于计算机的培训对A - B图进行准确视觉分析的效果。结果表明，所有参与者在接受关于变异性、水平、趋势和总体干预效果的基于计算机的培训后，都能准确地对A - B图进行视觉分析。这些视觉分析技能能够推广到手写数据图和真实数据图，并且在所有参与者掌握每个属性后的大约1天、1周、2周和1个月内得以保持。研究结果表明，基于计算机的培训提高了没有相关经验的成年人的准确视觉分析技能。
