Analysis of the Relationship Between the Content and Effectiveness of an Intervention based on the Layered Communication Model to Improve Communication

The Layered Communication Model (LCM) describes intersubjective development based on eight different communicative behaviors in three consecutive layers. Earlier studies showed that when the model is used in an intervention, the presence of many LCM behaviors increases from before to after the intervention. The present study aims to relate the content of the intervention to its effectiveness to learn whether and how the LCM can be used to improve communication. 15-minute videos of four student-teacher dyads were coded in ten-second intervals for the presence and absence of the eight LCM behaviors before, during and after the intervention. The intervention was divided into two phases: self-assessment and video feedback coaching. Intervention content was described based on the behaviors that were targeted for improvement during the two phases. Effectiveness was measured by calculating the percentage increase in presence between phases and by calculating effect sizes using a nonoverlap of all pairs method. Results showed that the second intervention phase (video feedback coaching) was most effective in terms of increasing the presence of LCM behaviors and creating larger effect sizes. Effectiveness measures decreased during the follow-up phase but were still higher than at baseline. Furthermore, effectiveness was higher for targeted behaviors than for untargeted behaviors. In conclusion, the LCM can be used as a tool to improve communication, especially when specific behaviors are clearly targeted and video feedback coaching is used to clarify how to work on improving the presence of those behaviors. The self-assessment phase needs adjustments to increase its effectiveness.

A universal framework for vocal interaction

Vocal interaction is an important feature of social behavior across species, however the relation between vocal communication in humans and nonhumans remains unclear. To enable comparative investigations of this topic, we review the literature pertinent to interactive language use and identify the superset of cognitive operations involved in generating communicative behavior. We posit these functions to comprise three multistep pathways: (1) the Content Pathway, which selects the movements constituting a response, (2) the Timing Pathway, which temporally structures responses, and (3) the Affect Pathway, which modulates response parameters as a function of internal state. These processing streams form the basis of the Convergent Pathways for Interaction (CPI) Framework, which can be used to contextualize communicative behaviors across species by identifying specific behavioral and cognitive analogues.

The Interpersonal Neuroscience of Social Learning

The study of the brain mechanisms underpinning social behavior is currently undergoing a paradigm shift, moving its focus from single individuals to the real-time interaction among groups of individuals. Although this development opens unprecedented opportunities to study how interpersonal brain activity shapes behaviors through learning, there have been few direct connections to the rich field of learning science. Our article examines how the rapidly developing field of interpersonal neuroscience is (and could be) contributing to our understanding of social learning. To this end, we first review recent research extracting indices of brain-to-brain coupling (BtBC) in the context of social behaviors and, in particular, social learning. We then discuss how studying communicative behaviors during learning can aid the interpretation of BtBC and how studying BtBC can inform our understanding of such behaviors. We then discuss how BtBC and communicative behaviors collectively can predict learning outcomes, and we suggest several causative and mechanistic models. Finally, we highlight key methodological and interpretational challenges as well as exciting opportunities for integrating research in interpersonal neuroscience with social learning, and we propose a multiperson framework for understanding how interpersonal transmission of information between individual brains shapes social learning.

Effects of a Systematic Augmentative and Alternative Communication Intervention Using a Speech-Generating Device on Multistep Requesting and Generic Small Talk for Children With Severe Autism Spectrum Disorder

Purpose The purpose of this study was to determine the effects of augmentative and alternative communication (AAC) intervention using a speech-generating device (SGD) on acquisition, maintenance, and generalization of multistep requesting and generic small talk in three children with severe autism spectrum disorder (ASD) between the ages of 7 and 13 years. Method A multiple-baseline design across participants combined with a posttreatment multiple-generalization-probe design was used to assess acquisition, generalization, and maintenance of target communicative behaviors with the experimenter and the participants' familiar communication partners (FCPs). Intervention was composed of systematic instruction in the use of an SGD using least-to-most prompting, constant time delay, error correction, and reinforcement. Results Visual analysis established a strong functional relationship between the independent variable and the two dependent variables (i.e., requesting preferred activities, engaging in generic small talk) for all three participants. Effect size indicator analyses corroborated these findings, indicating strong effects for performing multistep requesting and medium effects for engaging in generic small talk. All participants were able to generalize the acquired communicative behaviors to request new and untrained snacks and activities and engage in generic small talk with FCPs who were not part of the training. Maintenance of acquired communicative behaviors was demonstrated 3 weeks post completion of intervention. Conclusion This study provides preliminary evidence that AAC intervention using an SGD and incorporating least-to-most prompting, constant time delay, error correction, and reinforcement is effective in terms of multistep requesting and generic small talk behaviors in children with severe ASD.

ACCOMMODATING COMMUNICATION WITH CONVERSATIONAL AGENTS: EXAMINING THE PERCEPTIONS AND BEHAVIORS OF OLDER ADULTS WHEN USING VOICE ASSISTANT TECHNOLOGY

The purpose of this study is to examine the communicative relationship between older adults and conversational agents (CA), such as a Google Home Mini, to understand if and how interaction with AI-based voice technology affects perceptions, technological adoption, and, ultimately, human-machine communicative behaviors. Using the Communication Accommodation Theory (CAT) framework (Gallois & Giles, 2015), and the categorical schema as outlined in the Unified Theory of Adoption and Utilization of Technology (UTAUT) model (Venkatesh et al., 2003) of technology acceptance, we qualitatively assess the relationship between expectations for use and ongoing / post-interaction user attitudes. CAT focuses on the adjustments we make in our perceptions of and engagement in communicative behaviors. In other words, we enter into communicative situations with intentions and motivations derived from antecedent socio-historical context in mind. This squares with what the UTAUT model details as influencers of technological adoption and use: performance expectancy, effort expectancy, social influence, and facilitating conditions (Venkatesh et al., 2003). We use these constructs as a coding guideline to index data scraped from the Mini, and collected from surveys, interview transcripts, user journals, and field notes throughout a 10-week study. Historically, CAT is applied to human-human communication exchanges. As the theory posits that interpersonal relationships can and will influence motivations or intentions for dyadic communication, this makes sense. However, we argue that as AI-based voice technologies become more sophisticated as voice assistants enter our intimate spaces, the application of CAT to the human-machine communicative relationship is warranted.

Oxytocin facilitates communicative adjustment by upregulating broadband aperiodic neural activity

Oxytocin modulates various social behaviors. In humans, oxytocin has been shown to modulate recipient design, i.e. how communicators adjust to their presumed mutual knowledge. Here, we investigate electrophysiological correlates of the oxytocinergic modulation of recipient design. Fifty-one males were randomly assigned to receive double-blind intranasal administration of oxytocin or placebo. While acquiring magnetoencephalography, the participants engaged in a live communicative task with two different addressees, a child and an adult. Unbeknownst to the participants, a confederate played the role of both addressees, with matched communicative behaviors. All participants started the task by putting more emphasis on their communicative behaviors when they thought to be interacting with the child addressee. As the communication progressed, the oxytocin group reduced variability in their communicative adjustments, adapting more effectively than the placebo group to the matched communicative behavior of the addressees. The magnitude of this oxytocin-related dynamic communicative adjustment was proportional to increased broadband aperiodic power, an index of local synaptic activity, in the right prefrontal-temporal circuit. These findings indicate that oxytocin facilitates dynamic adjustments in recipient design by enhancing cortical signal-to-noise in a portion of the same cortical circuit known to support the production of novel communicative behaviors.

A Polarized Discourse: Effects of Opinion Differentiation and Structural Differentiation on Communication

In Western societies, many polarized debates extend beyond the area of opinions, having consequences for social structures within society. Such segmentation of society into opinion-based groups may hinder communication, making it difficult to reconcile viewpoints across group boundaries. In three representative samples from Australia and the Netherlands ( N = 1,206), we examine whether perceived polarization predicts the quality (harmony, comfort, and experience of negative emotions) and quantity (avoidance of the issue) of communication with others in the community. We distinguish between perceived opinion differentiation (i.e., the extent to which opinions in society are divided) and perceived structural differentiation (i.e., the extent to which society fissions into subgroups). Results show that although opinion differentiation positively predicts the discussion of societal issues, the belief that these opinions reflect a deeper societal divide predicts negative communication expectations and intentions. We discuss how polarization perceptions may reinforce communicative behaviors that catalyze actual polarization processes.

Dynamics of millennial employees' communicative behaviors in the workplace: the role of inclusive leadership and symmetrical organizational communication

PurposeWith a focus on millennial employees, this study investigates how employees engage in two types of employees' communicative behaviors (ECBs), that is, their voluntary communicative efforts to acquire and circulate tasks and managerial information (i.e. scouting) and to share and discuss positive and negative aspects of their organization with internal members (i.e. internal megaphoning). Through the lens of social exchange theory (SET) and symmetrical communication model, this study examines the effects of inclusive leadership and internal communication on active information behaviors of employees within their companies.Design/methodology/approachAn online survey was conducted with fulltime millennial employees working across various industry sectors in the US.FindingsSymmetrical internal communication influenced by inclusive leadership enhances employees' scouting behavior as well as positive internal megaphoning behavior. Positive and negative internal megaphoning with supervisors increases the scouting behavior of employees, whereas negative internal megaphoning with peers does not have a significant effect.Originality/valueThis study is among the first attempts to examine the effectiveness of leadership and strategic internal communication on millennial employees' diverse types of communicative behaviors.
