The present study aims to verify the impact of dynamic aids on learning L2 prepositions in relation to individual learner variables. Situated within the cognitive linguistics (CL) framework and differing from previous research, the present study hypothesizes that dynamic (animated) aids are not equally effective for all learners; rather, their effectiveness differs according to learners’ first languages (L1s) (Chinese or Japanese) and information-processing styles (verbalizers or imagers). To verify this hypothesis, we utilized learning materials comprised of static and dynamic images for three English spatial prepositions (above, on, over). After conducting a Style of Processing questionnaire, we administered three cloze tests (pretest, posttest, and delayed posttest) of target words to Taiwanese and Japanese participants (N = 109), whose L1s differed in terms of their linguistic proximity to English. Although no significant differences were found between the treatment groups in tests for all participants, the results were differentiated by individual factors. In results of a two-way ANOVA, Taiwanese participants showed significantly greater improvement from the pretest to posttest than Japanese participants when the participants used dynamic images, whereas the Japanese group made more learning gains from the posttest to the delayed posttest test. Moreover, imagers obtained more benefits from the visual aids, whether static or dynamic, than verbalizers. Our findings indicate that CL-based visual aids are beneficial and that individual factors, especially learners’ L1, may produce different learning effects, especially in multimedia environments.

This study investigates the roles of instruction explicitness and learning styles on the relative effectiveness of multimedia glossing with texts and cognitive linguistics-based image schemas presented in two modalities, i.e., static and animated, on Taiwanese college EFL students learning three polysemous prepositions: above, on, and over. Based on a pre-post-test design, the experiments consist of a free writing test and a gapfill test, respectively used to gauge the active and passive aspects of learners' receptive lexical gain. Three groups of intermediate learners were recruited, receiving the same text annotations but different treatments configured in presentation modes and explicitness: SI group with text-static imagery annotations under implicit instruction, AI group with text-animation annotations under implicit instruction, and AE group with text-animation annotations under explicit instruction. The results suggest the following: (1) animations, compared with static imagery, seem able to better enrich the meaningfulness of image schemas and elicit larger and more durable learning effects, especially on the more active aspects of the receptive gain; (2) explicit verbal cues enhanced the learning effects on the active aspects of the receptive gains; (3) visualizers benefit more from animations than verbalizers in both active and passive aspects of the receptive gains, especially if verbal cues are provided. Pedagogical suggestions include the utilization of image schema visual aids in a dynamic presentation mode accompanied by sufficient explicit instruction to optimize the effects of learning polysemous words.
