Visual-form systems in the cerebral hemispheres were examined in 3 experiments. After learning new types of visual forms, participants rapidly classified previously unseen prototypes of the newly learned types more efficiently when the forms were presented directly to the left hemisphere (in the right visual field) than when the forms were presented directly to the right hemisphere (in the left visual field). Neither previously seen nor previously unseen distortions of the prototypes were classified more efficiently when presented directly to the left hemisphere than when presented directly to the right hemisphere. Results indicate that an abstract visual-form system operates effectively in the left hemisphere and stores information that remains relatively invariant across the specific instances of a type of form to distinguish different types. Furthermore, this system functions relatively independently of another system that operates effectively in the right hemisphere and that stores details to distinguish specific instances of a type of form.
在3项实验中对大脑半球中的视觉形式系统进行了研究。在学习了新型视觉形式后,当这些形式直接呈现给左半球(右视野)时,参与者对新学类型中之前未见过的原型进行快速分类的效率,要高于当这些形式直接呈现给右半球(左视野)时的效率。无论是之前见过的还是之前未见过的原型变体,当直接呈现给左半球时,其分类效率并不比直接呈现给右半球时更高。结果表明,一个抽象的视觉形式系统在左半球有效运作,并存储在一类形式的特定实例中相对不变的信息,以区分不同类型。此外,该系统的功能相对独立于另一个在右半球有效运作的系统,后者存储用于区分一类形式的特定实例的细节。
