Vividness is one of the fundamental characteristics of visual mental imagery. The first research goal was to examine whether vividness that refer to imagery of pictorial object (color, texture, or shape) versus spatial (three dimensional structure, location, or mechanism) properties constitute separate vividness dimensions. The second goal was to develop a vividness questionnaire separately assessing dimensions of imagery vividness. In Study 1, 111 students (M age = 21.8 years, SD = 1.3) evaluated the vividness of imagery evoked by nine object and nine spatial items from the pilot version of the new Vividness of Object and Spatial Imagery (VOSI) questionnaire, completed a self-report assessment of object and spatial imagery, and rated their aptitudes in art and science. Analysis indicated that imagery vividness comprised object and spatial dimensions. Object vividness items were positively associated with the self-report measure and ratings of artistic abilities, whereas spatial vividness items were positively associated with self-report measure and ratings of science abilities. In Study 2, an independent sample of 205 students (M age = 21 years, SD = 1.7) completed the second version of the VOSI, art and science aptitude ratings, and a number of self-report and performance measures assessing object and spatial imagery. Object and spatial imagery vividness items loaded on factors with 28 retained items; this two-factor vividness model fit the data better than a unidimensional vividness model. The questionnaire had satisfactory Cronbach's α for object vividness scale (.88) and for spatial vividness scale (.85). Correlational analyses supported convergent and discriminative validity of the VOSI. While object imagery vividness and spatial imagery vividness share some underlying vividness variance, they are dissociated into separate dimensions.
生动性是视觉心理意象的基本特征之一。第一个研究目标是考察，涉及图画对象（颜色、纹理或形状）意象与空间（三维结构、位置或机制）属性的生动性是否构成不同的生动性维度。第二个目标是编制一份生动性问卷，分别评估意象生动性的维度。在研究1中，111名学生（年龄中位数 = 21.8岁，标准差 = 1.3）对新的物体与空间意象生动性（VOSI）问卷试行版中的九个物体项目和九个空间项目所唤起意象的生动性进行了评估，完成了一份关于物体和空间意象的自我报告评估，并对自己在艺术和科学方面的能力进行了评分。分析表明，意象生动性包括物体和空间维度。物体生动性项目与自我报告测量以及艺术能力评分呈正相关，而空间生动性项目与自我报告测量以及科学能力评分呈正相关。在研究2中，205名学生（年龄中位数 = 21岁，标准差 = 1.7）的独立样本完成了VOSI的第二版、艺术和科学能力评分，以及一些评估物体和空间意象的自我报告和表现测量。物体和空间意象生动性项目在由28个保留项目组成的因素上负荷；这个双因素生动性模型比单维生动性模型更能拟合数据。该问卷在物体生动性量表（.88）和空间生动性量表（.85）上具有令人满意的克朗巴哈α系数。相关分析支持了VOSI的聚合效度和区分效度。虽然物体意象生动性和空间意象生动性共享一些潜在的生动性方差，但它们被区分为不同的维度。
