Abstract: From the standpoint of nonverbal communication of social psycho-logy, this research analyses television instruction (TVI), infering thatdeprivation of visual information of nonverbal communication (VIONC)of the teacher is possibly one of the causes that impair the quality ofTVI. The hypothesis was tested by imitated TVI. Subjects acceptedinstructions of the same contents under three different conditions:Condition Ⅰ was traditional instruction; Condition Ⅱ was TVI containingVIONC of the teacher; Condition Ⅲ was TVI depriving VIONC of theteacher. Exams of instructing contents and attitude questionnaires weregiven after class. The results indicated that adding VIONC of theteacher in TVI promotes the achievement of the learners, and makesthe learners' attitudes more active. The negative influence of deprivityof VIONC is named "Screen Effect". Some new proposals are raised.
