Enrichment Effects of Gestures and Pictures on Abstract Words in a Second Language

Abstract

Laboratory research has demonstrated that multisensory enrichment promotes verbal learning in a foreign language (L2). Enrichment can be done in various ways, e.g., by adding a picture that illustrates the L2 word’s meaning or by the learner performing a gesture to the word (enactment). Most studies have tested enrichment on concrete but not on abstract words. Unlike concrete words, the representation of abstract words is deprived of sensory-motor features. This has been addressed as one of the reasons why abstract words are difficult to remember. Here, we ask whether a brief enrichment training by means of pictures and by self-performed gestures also enhances the memorability of abstract words in L2. Further, we explore which of these two enrichment strategies is more effective. Twenty young adults learned 30 novel abstract words in L2 according to three encoding conditions: (1) reading, (2) reading and pairing the novel word to a picture, and (3) reading and enacting the word by means of a gesture. We measured memory performance in free and cued recall tests, as well as in a visual recognition task. Words encoded with gestures were better remembered in the free recall in the native language (L1). When recognizing the novel words, participants made less errors for words encoded with gestures compared to words encoded with pictures. The reaction times in the recognition task did not differ across conditions. The present findings support, even if only partially, the idea that enactment promotes learning of abstract words and that it is superior to enrichment by means of pictures even after short training.

“…Several studies demonstrated that adding a gesture to the word to be learned is beneficial for learning, both for concrete and abstract words (Macedonia & Klimesch, 2014;Mayer, Yildiz, Macedonia, & Von Kriegstein, 2015;Repetto, Pedroli, & Macedonia, 2017). Indeed, enriching words with motor information allows to create multimodal representations of the word meaning, and to retrieve the new word more accurately.…”

Embodied Semantics in a Second Language: Critical Review and Clinical Implications

“…Namely, early L2 AoA has been associated with implicit L2 learning, which takes place in a naturalistic setting via sensorimotor experiences, while late L2 AoA has been associated with explicit learning, taking place in the setting of a traditional classroom via amodal instructions. Some studies contrasting different types of L2 learning have been mainly interested in learning and memory performances (e.g., Zimmer, 2001; Repetto et al, 2017; García-Gámez and Macizo, 2018). Other studies have tried to untie the type of learning from AoA.…”
