Challenges and insights for situated language processing: Comment on "Towards a computational comparative neuroprimatology: Framing the language-ready brain" by Michael A. Arbib.

Language-processing accounts are beginning to accommodate different visual context effects, but they remain underspecified regarding differences between cues, both during sentence comprehension and subsequent recall. We monitored participants' eye movements to mentioned characters while they listened to transitive sentences. We varied whether speaker gaze, a depicted action, neither, or both of these visual cues were available, as well as whether both cues were deictic (Experiment 1) or only speaker gaze (Experiment 2). Speaker gaze affected eye movements during comprehension similarly early to a single deictic action depiction, but significantly earlier than non-deictic action depictions; conversely, depicted actions but not speaker gaze positively affected later recall of sentence content. Thus, cue type and cue-language relations must be accommodated in characterising real-time situated language comprehension and subsequent recall of sentence content.

Distinct effects of different visual cues on sentence comprehension and later recall: The case of speaker gaze versus depicted actions.

Existing evidence has shown a processing advantage (or facilitation) when representations derived from a non-linguistic context (spatial proximity depicted by gambling cards moving together) match the semantic content of an ensuing sentence. A match, inspired by conceptual metaphors such as 'similarity is closeness' would, for instance, involve cards moving closer together and the sentence relates similarity between abstract concepts such as war and battle. However, other studies have reported a disadvantage (or interference) for congruence between the semantic content of a sentence and representations of spatial distance derived from this sort of non-linguistic context. In the present article, we investigate the cognitive mechanisms underlying the interaction between the representations of spatial distance and sentence processing. In two eye-tracking experiments, we tested the predictions of a mechanism that considers the competition, activation, and decay of visually and linguistically derived representations as key aspects in determining the qualitative pattern and time course of that interaction. Critical trials presented two playing cards, each showing a written abstract noun; the cards turned around, obscuring the nouns, and moved either farther apart or closer together. Participants then read a sentence expressing either semantic similarity or difference between these two nouns. When instructed to attend to the  on the cards (Experiment 1), participants' total reading times revealed interference between spatial distance (e.g., closeness) and semantic relations (similarity) as soon as the sentence explicitly conveyed similarity. But when instructed to attend to the  (Experiment 2), cards approaching (vs. moving apart) elicited first interference (when similarity was implicit) and then facilitation (when similarity was made explicit) during sentence reading. We discuss these findings in the context of a competition mechanism of interference and facilitation effects.
