Kosslyn (1980, 1983) theorized that performance measures on imagery tasks may vary as a function of the existence of independent processes in imaging ability. The present study determined whether improvement can be made in performance on such tasks with practice. It also considered whether performance on such tasks improves with practice and whether this improvement generalizes. Experiment 1 determined whether improvement in a mental rotation task generalizes to improvement in a geometric analogies task, with both tasks weighted in Kosslyn's find process, but not in a line drawing memory task weighted in Kosslyn's regenerate process. In Experiment 2, we examined generalization in improvement from a geometric analogies task to a mental rotation task. In Experiment 3, we tested whether improvement in an animal imagery task (Kosslyn, 1975) generalizes to improvement in a line drawing memory task, with both tasks weighted in Kosslyn's regenerate process, but not to improvement in a mental rotation task. Performance improved with practice on all tasks. Furthermore, performance improved from one task to another only if both tasks loaded on the same process.
科斯琳（1980年、1983年）提出理论，认为意象任务的表现测量可能会因成像能力中独立过程的存在而有所不同。本研究确定了通过练习是否能提高此类任务的表现。研究还考虑了此类任务的表现是否会随着练习而提高以及这种提高是否具有普遍性。实验1确定了心理旋转任务的提高是否能推广到几何类比任务的提高上，这两个任务在科斯琳的发现过程中具有权重，但在科斯琳的再生过程中加权的线条画记忆任务中则不然。在实验2中，我们研究了从几何类比任务到心理旋转任务的提高的普遍性。在实验3中，我们测试了动物意象任务（科斯琳，1975年）的提高是否能推广到线条画记忆任务的提高上，这两个任务在科斯琳的再生过程中具有权重，但不能推广到心理旋转任务的提高上。所有任务的表现都随着练习而提高。此外，只有当两个任务都加载在同一过程中时，表现才会从一个任务提高到另一个任务。
