Performance of 182 aphasic patients was examined on 11 PICA subtests for which the order of presentation of items is specified in an attempt to determine possible "tuning in" and "fading out" behavior. Results indicate that these phenomena occur as measurable patterns, which are to some degree dependent on the severity of aphasia as measured by each patient's overall PICA percentile.
对182名失语症患者在皮博迪图片词汇测验(PICA)的11个分测验上的表现进行了检查,这些分测验中项目呈现的顺序是特定的,目的是确定可能的“渐强”和“渐弱”行为。结果表明,这些现象以可测量的模式出现,在某种程度上取决于失语症的严重程度,而失语症严重程度是由每个患者的PICA总分百分位数衡量的。
