Competing hypotheses regarding the nature of visual processing were examined using the performance of 111 healthy older persons on the Warrington and James (1990) Visual Object and Space Perception Battery (VOSP). Confirmatory factor analysis indicated that a two-factor model corresponding to the Warrington theory of object and space perception as discrete domains showed excellent congruence with the data, despite limitations in the VOSP space perception tests that may have resulted in underestimation of model fit. Moreover, compared to a unidimensional model of visual processing, the Warrington model demonstrated a superior fit to the data. These findings add to the bodies of evidence supporting a dissociation between object- and space-perception abilities and defining the construct validity of the VOSP battery.
利用111名健康老年人在沃林顿和詹姆斯（1990年）视觉物体与空间感知成套测验（VOSP）上的表现，对关于视觉加工本质的相互竞争的假设进行了检验。验证性因素分析表明，尽管VOSP空间感知测验存在局限性，可能导致模型拟合度被低估，但与沃林顿关于物体和空间感知为离散领域的理论相对应的双因素模型与数据显示出极佳的契合度。此外，与视觉加工的单维模型相比，沃林顿模型对数据的拟合度更高。这些发现为支持物体感知能力和空间感知能力之间的分离以及界定VOSP成套测验的结构效度的证据体系增添了内容。
