“…There is in fact experimental data to suggest that peripheral perception is sufficient to enable the signs of Sign Language to be perceived in parallel with overt face fixation (Swisher 1990;Swisher, Christie and Miller 1989). In addition, Siple (1978) has proposed that signs requiring finer articulation are performed closer to the face in order for interlocutors to be able both to maintain eye contact and perceive the signs.…”

Since listeners usually look at the speaker's face, gestural information has to be absorbed through peripheral visual perception. In the literature, it has been suggested that listeners look at gestures under certain circumstances: 1) when the articulation of the gesture is peripheral; 2) when the speech channel is insufficient for comprehension; and 3) when the speaker him- or herself indicates that the gesture is worthy of attention. The research here reported employs eye tracking techniques to study the perception of gestures in face-to-face interaction. The improved control over the listener's visual channel allows us to test the validity of the above claims. We present preliminary findings substantiating claims 1 and 3, and relate them to theoretical proposals in the literature and to the issue of how visual and cognitive attention are related.

“…This is less likely to be true in the reverse case because the resting state of the hand is distinctly unlike the fine-aperture grasp necessary to pick up the small objects in the current study. The generation of a small grasp gesture could also involve more motion (in the shift from the neutral hand position to the grasp handshape), which would increase its detection in the visual periphery (see Swisher, 1990). Another possibility is that the identification of larger referents is already at ceiling.…”

In face-to-face interaction, speakers spontaneously produce manual gestures that can facilitate listeners' comprehension of spoken language. The present study explores the factors affecting the uptake and influence of gesture cues in situations where a speaker is referring to objects visible to the listener. In this context, the listener's attention must be distributed across various scene regions, potentially reducing the ability to draw on and apply gesture cues in real time. In two experiments, the instruction provided by a speaker (e.g., "pick up the candy") was accompanied by an iconic grasp gesture (produced alongside the verb) that reflected the size/shape of the intended target. Effects on listeners' comprehension were compared with a no-gesture condition. Experiment 1 (audiovisual gating task) showed that, under simplified processing circumstances, gesture cues allowed earlier identification of intended targets. Experiment 2 (eye tracking) explored whether this facilitation is found in real-time comprehension, and whether attention to gesture information is influenced by the acoustic environment (quiet vs. background noise). Measures of gaze position showed that although the speaker's gesturing hand was rarely fixated directly, gestures did facilitate comprehension, particularly when the target object was smaller relative to alternatives. The magnitude of the gesture effect was greater in quiet than in noise, suggesting that the latter did not provoke listeners to increase attention to gesture to compensate for the challenging auditory signal. Together, the findings clarify how situational factors influence listeners' attention to visual information during real-time comprehension.
