Today, access to various audiovisual programs such as cartoons has become very easy through the development of audiovisual technologies such as CD and DVD players. In the same line, many studies have emphasized on the psychological values of utilizing cartoons in language learning. Accordingly, the present study aims at investigating the effect of exposure of cartoons on language proficiency at the intermediate level. To this end, a language proficiency test was administered to 90 language learners. Then, a smaller population of 40 language learners were selected as intermediate language learners and randomly divided into two groups, i.e. group one and group two. During the experiment, group one was instructed via the use of cartoons. In contrast, group two was instructed by a sample of selected audiovisual programs rather than cartoons. At the end of the study which lasted for 6 weeks, both groups took another sample language proficiency test to find out whether or not if any changes happened regarding their language proficiency. The results of the post-test showed that the first group participants who had exposure to cartoons had lesser language proficiency improvement in comparison to the second group of participants who had exposure to non-cartoons programs. This proved that the quality of the language input should be given initial importance.
