And Task

Over the past years, extensive research has been dedicated to developing robust platforms and data-driven dialog models to support long-term human-robot interactions. However, little is known about how people's perception of robots and engagement with them develop over time and how these can be accurately assessed through implicit and continuous measurement techniques. In this paper, we explore this by involving participants in three interaction sessions with multiple days of zero exposure in between. Each session consists of a joint task with a robot as well as two short social chats with it before and after the task. We measure participants' gaze patterns with a wearable eye-tracker and gauge their perception of the robot and engagement with it and the joint task using questionnaires. Results disclose that aversion of gaze in a social chat is an indicator of a robot's uncanniness and that the more people gaze at the robot in a joint task, the worse they perform. In contrast with most HRI literature, our results show that gaze toward an object of shared attention, rather than gaze toward a robotic partner, is the most meaningful predictor of engagement in a joint task. Furthermore, the analyses of gaze patterns in repeated interactions disclose that people's mutual gaze in a social chat develops congruently with their perceptions of the robot over time. These are key findings for the HRI community as they entail that gaze behavior can be used as an implicit measure of people's perception of robots in a social chat and of their engagement and task performance in a joint task.

Set Sharing

A central issue in the study of joint task performance has been one of whether co-acting individuals perform their partner’s part of the task as if it were their own. The present study addressed this issue by using joint task switching. A pair of actors shared two tasks that were presented in a random order, whereby the relevant task and actor were cued on each trial. Responses produced action effects that were either shared or separate between co-actors. When co-actors produced separate action effects, switch costs were obtained within the same actor (i.e., when the same actor performed consecutive trials) but not between co-actors (when different actors performed consecutive trials), implying that actors did not perform their co-actor’s part. When the same action effects were shared between co-actors, however, switch costs were also obtained between co-actors, implying that actors did perform their co-actor’s part. The results indicated that shared action effects induce task-set sharing between co-acting individuals.

Sensory Modalities

In daily life, humans constantly process information from multiple sensory modalities (e.g., vision, audition). Information across sensory modalities may (or may not) be combined to form the perception of a single event via the process of multisensory integration. Recent research suggests that performing a spatial crossmodal congruency task jointly with a partner affects multisensory integration. To date, it has not been investigated whether multisensory integration in other crossmodal tasks is also affected by performing a task jointly. To address this point, we investigated whether joint task performance also affects perceptual judgments in a crossmodal motion discrimination task and a temporal order judgment task. In both tasks, pairs of participants were presented with auditory and visual stimuli that might or might not be perceived as belonging to a single event. Each participant in a pair was required to respond to stimuli from one sensory modality only (e.g., visual stimuli only). Participants performed both individual and joint conditions. Replicating earlier multisensory integration effects, we found that participants' perceptual judgments were significantly affected by stimuli in the other modality for both tasks. However, we did not find that performing a task jointly modulated these crossmodal effects. Taking this together with earlier findings, we suggest that joint task performance affects crossmodal results in a manner dependent on how these effects are quantified (i.e., via responses time or accuracy) and the specific task demands (i.e., whether tasks require processing stimuli in terms of location, motion, or timing).

As If

Studies on joint task performance have proposed that co-acting individuals co-represent the shared task context, which implies that actors integrate their co-actor’s task components into their own task representation as if they were all their own task. Evidence supporting this proposal has been supported by results of joint tasks in which each actor is assigned a single response where selecting a response is equivalent to selecting an actor. The present study used joint task switching, which has previously shown switch costs on trials following the actor’s own trial (intrapersonal switch costs) but not on trials that followed the co-actor’s trial (interpersonal switch costs), suggesting that there is no task co-representation. We examined whether interpersonal switch costs can be obtained when action selection and actor selection are confounded as in previous joint task studies. The present results confirmed this prediction, demonstrating that switch costs can occur within a single actor as well as between co-actors when there is only a single response per actor, but not when there are two responses per actor. These results indicate that task co-representation is not necessarily implied even when effects occur across co-acting individuals and that how the task is divided between co-actors plays an important role in determining how the actors represent the divided task components.

Slight Advantage

Spatial and sequential tasks which were performed both independently and jointly were compared for 40 college undergraduates grouped by sex and dominant hand. The two tasks were selected based on prior research suggesting that each is controlled in a different brain hemisphere. When the two tasks were performed independently there was no handedness effect nor was there any sex-hand interaction. There was an expected slight spatial superiority of males. However, when both tasks were performed simultaneously, there was a significant advantage for right-handers and again a slight advantage for males. Results were attributed to the hemispheric interference left-handers experienced on the joint task due to their less distinct hemispheric specialization.

New Challenges

Partially automated vehicles, in which automation performs parts of the driving task, introduce new challenges of automation monitoring and human-automation teaming to the driving experience. We describe a new method for measuring whether operators mentally represent automated task performance using a version of the joint task-switching (JTS) task paradigm. In the JTS task, an operator and a teammate take turns performing two intermixed tasks. Following takeover from the teammate, task-switching costs (slower responses following a task switch vs repetition) indicate that the operator mentally represents the teammate’s performance. We measured performance following task switches and repetitions with and without a takeover from automation. Switch costs disappeared following takeovers, indicating a lack of representation of the prior automated task. We discuss how task switch costs following takeovers can serve as indirect measures of whether operators mentally represent automated task performance in mixed automation situations.
