Triadic spatial distance and social media assets for food tourists

ABSTRACT This paper examines the potential impact of the triadic social interaction instigated by spatial distance between author, reader, and business that detects tourists’ geographical decision patterns. A social media asset for brands is a digital presence that encourages positive consumer responses in media communication. Using 2,129 items of author-reader-business paired review data, the findings indicate that geographical proximity between the review triad has assimilated patterns to assess reviews. Spatial regression analysis visualized spatial heterogeneity across US regions, showing that a lower spatial distance between tourists and businesses positively improved media assets; in contrast, close spatial proximity had a strong impact among peer tourists. As spatially heterogeneous tourists positively accept media sharing toward the business, the review triad model imposes the varying effects of triadic spatial distance that helps tourism policymakers implement an effective location-based social media marketing strategy for the food tourism industry.

Why is it difficult for children and adults to follow a person's eye gaze in polynomial social relationships with compound audio-visual stimuli: An eye-tracking study.

Acquiring triadic social interactions could facilitate language and communication skills in early infancy. However, studies have rarely investigated polynomial relationships, defined as relationships among the self, two or more people, and objects. During the development from a child to an adult, the responsiveness to a preferred stimulus modality changes from visual to auditory dominance. Nevertheless, how people observe compound visual stimuli in polynomial social relationships and why it is difficult to ignore auditory cues remain unclear. Moreover, there is a need to identify differences between children's and adults' observing latencies in the time to the first fixation when detecting a stimulus. This study examined whether participants (24 adults and 19 children) demonstrated similar gaze patterns under triadic and polyadic conditions. The participants observed a target visual stimulus looked at by a face stimulus while we presented spoken names, either congruent or incongruent with the target visual stimulus. The results indicated that when the number of people in social relationships increased, children and adults decreased fixations on the target face and the stimulus and showed a shorter mean fixation duration on the face. Moreover, children had longer latencies and more fixation errors for the target stimulus, which might reflect children's difficulties in communicating with others. We expect that understanding children's communication transition from triadic to polynomial social relationships with audio-visual stimulus congruencies would facilitate understanding language development and social communication patterns.

Locomotion development and infants' object interaction in a day-care environment.

This longitudinal study examined the relationship between the development of locomotion and infants' interaction with others involving objects. Observations took place in a multi-person situation-a day-care class-for one-year-old infants for 1year. The study participants were 13 infants and 7 caregivers (all Japanese). Frequencies of infants' manual contact with objects and moving before contact with them did not differ according to locomotion developmental level. However, infants who began walking engaged in more social interactions than those who were cruising or crawling. Throughout all locomotor developmental periods, social interactions increased in frequency when more caregivers were present. As infants began to walk, they moved more prior to social interactions, had more frequent bidirectional and triadic social interactions, and moved and interacted more often with others during a single object episode. These results suggest that crawlers' engagement with objects is relatively object-oriented, while for walkers, locomotion seems to be driven by social stimuli. Infants who have begun to walk moved among caregivers and peers in a multi-person environment and developed more elaborated social interactions through objects.

Alpha and theta brain activity in 9-month-old infants during a live referential gaze paradigm.

The ability to establish a connection between the direction of the other's gaze and the object that is observed has important implications in the development of social cognition and learning. In this study, we analyzed alpha and theta band oscillations in one group of 9-month-old infants by implementing a face-to-face live paradigm, which presented the infants with a triadic social interaction with a real human being. We compared neural activations in two experimental conditions: Congruent and Incongruent gaze shift following the appearance of an object. In the Incongruent object-gaze shift condition, we observed an increase of the theta power in comparison with the Congruent condition. We also found an enhancement of the alpha activity during the Congruent versus the Incongruent object-gaze condition. These findings confirm the involvement of the theta and alpha band activity in the detection of the gaze of others when it shifts toward a referential target. We consider that the theta band modulation could be associated with the processing of unexpected events. Furthermore, the increase of the alpha band activity during the Congruent object-gaze condition seems to be in agreement with prior findings on the mechanisms of internally controlled attention that emerge before the first year of life. The implementation of a live paradigm elicited a partially different oscillatory pattern in comparison with non-live standard paradigms, supporting the importance of an ecological set-up reproducing real-life conditions to study the development of social cognition.

Third-party vocal intervention in the proboscis monkey (Nasalis larvatus)

Vocal intervention is a triadic social interaction, where a third party responds vocally to a conflict between group members, minimizing the costs of aggression in response to the intervention. Because there is little information on vocal third-party intervention in nonhuman mammals, we investigated whether adult male proboscis monkeys use the bray vocalization as a vocal third-party intervention signal to intervene in intragroup conflicts. First, we audio-recorded 1,811 vocalizations from 17 free-ranging proboscis monkey groups in the Lower Kinabatangan Wildlife Sanctuary, analyzing 378 vocal responses of the adult male to agonistic vocal exchanges (shrieks) of group members. Second, we video- and audio-recorded five habituated groups in the Labuk Bay Proboscis Monkey Sanctuary investigating the context of these vocalizations and the conflict dyads evoking vocal support. We found that adult males of one-male/multifemale groups mainly uttered bray vocalizations, whereas females, immatures, and infants uttered shrieks in intragroup conflicts or in response to other animal species. The adult male uttered significantly more often brays after agonistic shrieks than expected based on the overall occurrence of brays. Brays ended 65% of agonistic conflicts, which were accompanied by vocalizations of the conflict partners and occurred more often after conflicts between females than between offspring. This suggests that the bray functions as a vocal third-party intervention signal for intragroup conflict resolution. We suggest that living in the high canopies of the tropical rainforest might restrict direct access to conflict partners and prevent physical intervention, favoring the evolution of the bray as a third-party vocal intervention signal.

Understanding Tourist Citizenship Behavioral Intentions: The Role of Social Interactions and Brand Perceptions

ABSTRACT This study integrates tourists’ social interaction quality and experience with a casino brand to examine changes of tourist citizenship behavioral intentions between pre- and post-casino trips. A two-stage sampling method was deployed with data driven in the casino industry: a random sampling approach to select casino properties followed by a quota sampling approach to respondent selection. It advances the casino tourism literature by delineating that brand experience and attachment partially mediate the relationships leading from a triadic social interaction process to changes in casino tourists’ citizenship behavioral intentions. Moreover, branded casinos relish a greater change in such intentions, as casino tourists may feel the urge to reciprocate the tourist resources geared toward them and associate themselves with these brands.

Show Me the World: Object Categorization and Socially Guided Object Learning in Infancy

AbstractHow infants acquire knowledge about animate beings and physical objects has been of interest to developmental psychologists for many years. In this article, we provide evidence suggesting that by 7 months, infants have formed a global animate‐inanimate distinction that seems to be based on previously acquired knowledge. This knowledge may allow infants to analyze triadic social interactions involving another animate being and a physical object in more complex ways. Whereas 3‐ to 4‐month‐olds respond to object‐directed social cues such as eye gaze or facial expressions more or less automatically, 9‐ to 12‐month‐olds seem to integrate social and object knowledge to allocate their attentional resources. Twelve‐month‐olds can even detect person‐specific preferences for an entire category of objects. Based on this evidence, we conclude that infants’ learning about social beings and physical objects is closely related, but changes substantially in preverbal children.

Triadic social interactions operate across time: a field experiment with wild chimpanzees

Social animals cooperate with bonding partners to outcompete others. Predicting a competitor's supporter is likely to be beneficial, regardless of whether the supporting relationship is stable or transient, or whether the support happens immediately or later. Although humans make such predictions frequently, it is unclear to what extent animals have the cognitive abilities to recognize others' transient bond partners and to predict others' coalitions that extend beyond the immediate present. We conducted playback experiments with wild chimpanzees to test this. About 2 h after fighting, subjects heard recordings of aggressive barks of a bystander, who was or was not a bond partner of the former opponent. Subjects looked longer and moved away more often from barks of the former opponents' bond partners than non-bond partners. In an additional experiment, subjects moved away more from barks than socially benign calls of the same bond partner. These effects were present despite differences in genetic relatedness and considerable time delays between the two events. Chimpanzees, it appears, integrate memories of social interactions from different sources to make inferences about current interactions. This ability is crucial for connecting triadic social interactions across time, a requirement for predicting aggressive support even after a time delay.

History of interaction and task distribution modulate action simulation

Recent work suggests that social interaction modulates the sensorimotor simulation of an observed action. Recording electroencephalograms during a triadic social interaction, we investigated the effects of two specific aspects of social interaction on action simulation: the recent history of interaction and the distribution of individual parts of a simple joint task between actors. Activation of sensorimotor areas was larger during observation of the individual action of an interaction partner compared to observation of the same action of a person performing only individual actions, unless this person had interacted with the observer in the recent past. In addition, it is likely that the participants simulated the action onset of the individual actions of their interaction partner, but only when their partner was the one who initiated the joint action. These results demonstrate that action simulation can be modulated by present and past interactions between the actor and the observer and by how a joint task is distributed between actors.

Carryover effect of joint attention to repeated events in chimpanzees and young children

Gaze following is a fundamental component of triadic social interaction which includes events and an object shared with other individuals and is found in both human and nonhuman primates. Most previous work has focused only on the immediate reaction after following another’s gaze. In contrast, this study investigated whether gaze following is retained after the observation of the other’s gaze shift, whether this retainment differs between species and age groups, and whether the retainment depends on the nature of the preceding events. In the social condition, subjects (1- and 2-year-old human children and chimpanzees) witnessed an experimenter who looked and pointed in the direction of a target lamp. In the physical condition, the target lamp blinked but the experimenter did not provide any cues. After a brief delay, we presented the same stimulus again without any cues. All subjects looked again to the target location after experiencing the social condition and thus showed a carryover effect. However, only 2-year-olds showed a carryover effect in the physical condition; 1-year-olds and chimpanzees did not. Additionally, only human children showed spontaneous interactive actions such as pointing. Our results suggest that the difference between the two age groups and chimpanzees is conceptual and not only quantitative.

Favouritism in the motor system: social interaction modulates action simulation

The ability to anticipate others' actions is crucial for social interaction. It has been shown that this ability relies on motor areas of the human brain that are not only active during action execution and action observation, but also during anticipation of another person's action. Recording electroencephalograms during a triadic social interaction, we assessed whether activation of motor areas pertaining to the human mirror-neuron system prior to action observation depends on the social relationship between the actor and the observer. Anticipatory motor activation was stronger when participants expected an interaction partner to perform a particular action than when they anticipated that the same action would be performed by a third person they did not interact with. These results demonstrate that social interaction modulates action simulation.

Selective prefrontal cortex responses to joint attention in early infancy

The process by which two people share attention towards the same object or event is called joint attention. Joint attention and the underlying triadic representations between self, other person and object are thought to be unique to humans, supporting teaching, cooperation and language learning. Despite the progress that has been made in understanding the behavioural importance of joint attention during early social development, almost nothing is known about the brain substrate that supports joint attention in the developing infant. We examined responses in five-month-old infants' prefrontal cortex during triadic social interactions using near-infrared spectroscopy. The results demonstrate that, even by the age of five months, infants are sensitive to triadic interactions and, like adults, they recruit a specific brain region localized in left dorsal prefrontal cortex when engaged in joint attention with another person. This suggests that the human infant is neurobiologically prepared for sharing attention with other humans, which may provide the basis for a wide variety of uniquely human social and cultural learning processes.

Interventions in social behaviour in a herd of mares and geldings

Social dynamics and maintenance of social cohesion were studied by analysing social interventions in two groups of horses consisting of adult mares, their offspring, adult geldings and sub-adults. The animals were observed for a total of 1316 h. All relevant dyadic and triadic social interactions, including initial behaviour, possible intervention and outcome, were recorded. The main question was: do horses use interventions in affiliative interactions to safeguard their social network? Horses were significantly more likely to intervene in allogrooming or play interactions that involved a preferred partner. The stronger the preferred association in allogrooming, the higher the likelihood the intervener took over allogrooming with an initial dyad member. Interveners originating from two newly introduced groups ( n = 3 and 5), intervened significantly more often when a member of their own group allogroomed with an unfamiliar horse. In play, no correlation with unfamiliarity was found. Overall, the intervening horses stopped more than half of the initial allogrooming interactions, and a third of all interactions. Therefore, social facilitation cannot sufficiently explain interference behaviour. This study shows that maintaining relationships with preferred partners is important to horses and has implications for equine husbandry and management.

Imitation performance in toddlers with autism and those with other developmental disorders.

The present study sought to examine the specificity, developmental correlates, nature and pervasiveness of imitation deficits very early in the development of autism. Subjects were 24 children with autism (mean age 34 months), 18 children with fragile X syndrome, 20 children with other developmental disorders, and 15 typically-developing children. Tasks included manual, oral-facial, and object oriented imitations, developmental measures, joint attention ability, and motor abilities. Children with autism were found to be significantly more impaired in overall imitation abilities, oral-facial imitation, and imitations of actions on objects than children in all of the other groups. Imitation skills of young children with fragile X syndrome were strongly influenced by the absence or presence of symptoms of autism. For children with autism, imitation skills were strongly correlated with autistic symptoms and joint attention, even when controlling for developmental level. For comparison groups, imitation was related to other developmental abilities including play, language, and visual spatial skills. Neither motor functioning nor social responsivity accounted for a significant amount of variance in imitation scores, when controlling for overall developmental level, which accounted for much of the variation in imitation ability. Simple imitation skills were differentially impaired in young children with autism, and lack of social cooperation did not account for their poor performance. In autism, imitation skills clustered with dyadic and triadic social interactions and overall developmental level, but were not related to play or language development. For comparison children, all these areas were inter-related. Hypotheses about a specific dyspraxic deficit underlying the imitation performance in autism were not supported.

A Comparison of the Effects of Organismic and Setting Variables on the Social Interaction Behavior of Children with Developmental Disabilities and Autism

In this investigation, the effects of four setting events and two organismic variables on the social behavior of children with developmental disabilities and autism were compared. In Study 1, social interactions within dyads composed of one student with disabilities and one nondisabled peer were compared to triads composed of two nondisabled peers and one child with disabilities. In addition, differential effects of peer tutoring and peer initiation interventions were determined. In Study 2, the effects of high- and low-status peers within triadic social interaction groupings were examined to determine effects on both the students with disabilities and their nondisabled peers. The results suggest that peer dyads, the cooperative peer intervention, and triads composed of two high-status nondisabled peers were most effective in promoting positive social interactions for the participants with disabilities. Furthermore, there seemed to be no real benefit to low-status peers related to participation in this second investigation. Results are discussed in relation to the effective and efficient use of programs designed to effect social competence and inclusion.

Analysis of behavioral durations in observational studies of social interaction.

Many social science disciplines investigate dyadic or triadic social interaction by recording the interactive behaviors as qualitative codes. This article introduces a method for analyzing and interpreting variation in the durations of coded behaviors obtained during such interactions. Using survival analysis and event history analysis as its basis, this article discusses the use of regression techniques that enable the researcher to assess how the distributions of behavioral durations depend on covariate observations. An analysis of conflicts between mothers and children illustrates the discussion, using the proportional hazards model. Behavioral and attitudinal differences among the mother-son dyad predicted variation in the durations of mothers' negative statements to their sons.
