This article presents an experimental analysis of several cybersecurity risks affecting the human attack surface of Fairmont State University, a mid-size state university. We consider two social engineering experiments: a phishing email barrage and a targeted spearphishing campaign. In the phishing experiment, a total of 4,769 students, faculty, and staff on campus were targeted by 90,000 phishing emails. Throughout these experiments, we explored the effectiveness of three types of phishing awareness training. Our results show that phishing emails that make it (...) through IT’s defenses pose a clear and present threat to large educational organizations. Moreover, we found that simple, visual, instructional guides are more effective training tools than long documents or interactive training. (shrink)

This study belongs to the ethnomethodological tradition of identifying the everyday practices accounting for the oiled machinery of social organization and applies this approach to understanding direction light usage. We observe a set of episodes videorecorded in North-East Italy in the urban traffic. We first unpack the meaning of direction light usage from a pragmatic perspective and then test our interpretation against the cases in our collection that seem to deviate from it. We argue that direction lights’ usage works as (...) an announcement to some road users and a request to a subset of them; in both cases, direction lights convey contextualized (indexical) coordinates about the vehicle’s prospective trajectory. We then explain the cases in which signaling is omitted and draw some implications for traffic coordination and safety. (shrink)

Canid and human barks and growls were examined in videotapes of 24 humans (Homo sapiens) and 24 dogs (Canis familiaris) playing with familiar and unfamiliar cross-species play partners. Barks and growls were exhibited by 9 humans and 9 dogs. Dogs barked and (less often) growled most frequently when being frustrated by humans and/or engaged in competitive games, and less often when being chased or inviting chase, and being instigated or captured. Dogs never growled when playing with an unfamiliar human, and (...) humans did so rarely when playing with an unfamiliar dog. Humans growled and (less often) barked most frequently when chasing and capturing the dog, less often when engaging in competitive games, being frustrated by the dog, and/or instigating the dog, and rarely when showing or throwing an object. Dog barks were most often requests for the human to make an object available to the dog. Dog growls were often pretend threats when competing for an object or being frustrated by the human’s actions. Human barks and growls were typically pretend threats, and were sometimes used to emphasize simultaneous behaviors. Human barks and growls allow humans to connect with their canid partner. (shrink)

Previous research shows that females use more exclamation marks than males, often to establish rapport. The purpose of the present studies was to test whether people associate texters’ use of exclamation marks with friendliness and femaleness. If this association is due to normative expectations, we hypothesized that females would appear less friendly if they did not use an exclamation mark in texting. In Study 1, participants rated a texter using an exclamation mark to be highly female and highly friendly. The (...) gender results disappeared when friendliness was controlled for. In Study 2, we tested whether friendliness ratings decreased if texters violated gender-associated punctuation. Participants rated a texter with a gendered name on friendliness. Regardless of gender, participants inferred greater friendliness to texters using an exclamation mark. That is, there was no evidence of a cost for violating this gender expectation. We conclude that people predict that a texter using an exclamation mark is likely to be female, but do not penalize females for not using an exclamation mark. (shrink)

Small unmanned aerial systems (sUAS) are used more regularly and widely in disaster response. Like other personnel involved in disaster response, the sUAS pilots work for long periods, experience extreme stress and fatigue. They often arrive at the disaster fatigued (due to long drives to get there). However, unlike other personnel in this domain, there is little research on the effects of fatigue on sUAS pilots. Our experiences with a series of three real-world deployments highlight the challenges of conducting human (...) factors research during disaster response and recovery. We specifically present lessons learned from having participant researchers embedded in three disasters with the sUAS pilot teams. These lessons result in a set of feasible and non-interruptive methods and metrics for conducting human factors research during field events. Preliminary results and recommended next steps are presented. (shrink)

On reviewing the literature regarding acceptance and trust in human-robot interaction (HRI), there are a number of open questions that needed to be addressed in order to establish effective collaborations between humans and robots in real-world applications. In particular, we identified four principal open areas that should be investigated to create guidelines for the successful deployment of robots in the wild. These areas are focused on: (1) the robot’s abilities and limitations; in particular when it makes errors with different severity (...) of consequences, (2) individual differences, (3) the dynamics of human-robot trust, and (4) the interaction between humans and robots over time. In this paper, we present two very similar studies, one with a virtual robot with human-like abilities, and one with a Care-O-bot 4 robot. In the first study, we create an immersive narrative using an interactive storyboard to collect responses of 154 participants. In the second study, 6 participants had repeated interactions over three weeks with a physical robot. We summarise and discuss the findings of our investigations of the effects of robots’ errors on people’s trust in robots for designing mechanisms that allow robots to recover from a breach of trust. In particular, we observed that robots’ errors had greater impact on people’s trust in the robot when the errors were made at the beginning of the interaction and had severe consequences. Our results also provided insights on how these errors vary according to the individuals’ personalities, expectations and previous experiences. (shrink)

In two separate experiments, we examined 17-month-olds’ imitation in a third-party context. The aim was to explore how seeing another person responding to a model’s novel action influenced infant imitation. The infants watched while a reliable model demonstrated a novel action with a familiar (Experiment 1) or an unfamiliar (Experiment 2) object to a second actor. The second actor either imitated or did not imitate the novel action of the model. Fewer infants imitated the model’s novel behavior in the non-imitation (...) condition than in the imitation condition in Experiment 1. In Experiment 2, infants’ likelihood of imitating was not influenced by whether they had watched the second actor imitating the model’s novel action with the unfamiliar object. The findings indicate that infants take into account a second adult’s actions in a third party context when infants receive information that contradicts their existing knowledge and when it corresponds with their own experiences. If infants do not have prior knowledge about how to handle a certain object, then the second adult’s actions do not seem to matter. (shrink)

The first studies that sought to establish two-way communication between humans and great apes led to important findings but were nevertheless heavily criticized for their training methods, testing procedures, and claims. More recently, hundreds of pet owners around the world have begun training domesticated animals to use Augmentative Interspecies Communication (AIC) soundboard devices, contributing to the first ever large-scale study on interspecies communication. Here, we introduce our scientific approach to our global citizen science project, where we will investigate how dogs (...) and cats use AIC devices, building an incremental research program starting from their associative learning of buttons to determining how AIC device use might impact their welfare and their capacity for symbolic representation. We discuss how our multi-faceted approach can alleviate many of the concerns regarding the original studies performed with apes, achieving larger sample sizes, ample documentation of training techniques, and testing animals’ performance in controlled experimental settings.

Birds produce different types of sounds in different contexts such as begging for food in youngsters, alerting to a danger, defending a territory or attracting a sexual partner. About half of the bird species are able to transform their vocalizations through imitation, improvisation or invention of sounds. Here we review the different experimental procedures that have been used to study the learning capacities of birds in the vocal domain and in the auditory domain, with a particular emphasis on recent technological (...) developments. Nowadays, it is possible to record individual vocalizations of birds living in social groups or to record continuously the vocal ontogeny of birdsong. In conditioning experiments, new paradigms have successfully replaced food rewards with a socio-sexual reward. It is possible to engage in vocal interactions with a bird using dedicated computer systems. In both the laboratory and more recently in the field, different techniques have been used to train young oscine songbirds to learn from acoustic models. The use of virtual social environments and robots as social agents are also promising avenues. All together, these new techniques will permit researchers to explore more deeply the umwelt of bird species. (shrink)

The numerous systems designed to facilitate animals’ use of computers often are specific to the animals involved, their unique context, and the applications – enrichment among them. Hence, several development methods have arisen in parallel, largely transposed from the human-computer interaction (HCI) domain. In light of that prior work, the paper presents a step-by-step guide for iteratively designing and constructing interactive computers for animals, informed by the rich history of HCI yet applying animal-centred principles, to enrich animal-computer interaction. For each (...) stage in the iterative design (requirements, ideation, prototyping, and testing), the author reflects on real-world experience of building interactive devices for various animals. The paper concludes with overarching considerations vital for future practice of developing interactive computers for animals. Thus, it serves as a valuable reference and information source for researchers designing novel computer systems for animals. (shrink)

There is a strong disconnect between humans and other species in our societies. Zoos particularly expose this disconnect by displaying the asymmetry between visitors in search of entertainment, and animals often suffering from a lack of meaningful interactions and natural behaviors. In zoos, many species are unable to mate, raise young, or exhibit engagement behaviors. Enrichment is a way to enhance their quality of life, enabling them to express natural behaviors and reducing stereotypies. Prior work on sound-based enrichment and interactivity (...) suggest that a better understanding of animals’ sensory needs and giving them options to shape their surroundings can yield substantial benefits. However, current zoo management and conservation practices lack tools and frameworks to leverage innovative technology to improve animal well-being and zookeepers’ ability to care for them. Ethical considerations are called for in developing such interventions as human understanding of animals’ worlds is still limited, and assumptions can have detrimental consequences. Based on several interventions, four principles are proposed to guide a more systematic implementation of sonic enrichment in zoos. The goal is to lay the groundwork for the design of the zoos of the future, with a focus on sounds, for the benefit of the animals. (shrink)

Understanding how animals might make sense of the interfaces they interact with is important to inform the design of animal-centered interactions. In this regard, biosemiotics provides a useful lens through which to examine animals’ interactions with interfaces and the sensemaking mechanisms that might underpin such interactions. This paper leverages Uexküll’s Umwelt theory, Peirce’s logic of sign relations and Gibson’s theory of affordances to analyze examples of dogs’ interactions with interfaces, particularly the role of the semiotic mechanisms of indexicality and isomorphism. (...) Based on these analyses, the paper derives design implications, and proposes a semiotic framework to support the analysis and design of canine-centered interactions. The framework could be subsequently extended to support the analysis and design of interactive systems for other species. (shrink)

The field of animal-computer interfaces has a longer history than one might at first suppose. In this Introduction, I first discuss some of the early attempts to integrate computers into the study of animal cognition, communication, and behavior and how they provided the groundwork for subsequent research in nonhuman-computer interfaces. I then summarize the various contributions to this special issue, emphasizing how they provide a snapshot into the current state of the field. I close by emphasizing the value of this (...) work but also by suggesting some potential pitfalls of which we must also be aware. (shrink)

Phone calls are an essential communication channel in today’s contact centers, but they are more difficult to analyze than written or form-based interactions. To that end, companies have traditionally used surveys to gather feedback and gauge customer satisfaction. In this work, we study the relationship between self-reported customer satisfaction (CSAT) and automatic utterance-level indicators of emotion produced by affect recognition models, using a real dataset of contact center calls. We find (1) that positive valence is associated with higher CSAT scores, (...) while the presence of anger is associated with lower CSAT scores; (2) that automatically detected affective events and CSAT response rate are linked, with calls containing anger/positive valence exhibiting respectively a lower/higher response rate; (3) that the dynamics of detected emotions are linked with both CSAT scores and response rate, and that emotions detected at the end of the call have a greater weight in the relationship. These findings highlight a selection bias in self-reported CSAT leading respectively to an over/under-representation of positive/negative affect. (shrink)

Symbolic representation acquisition is the complex cognitive process consisting of learning to use a symbol to stand for something else. A variety of non-human animals can engage in symbolic representation learning. One particularly complex form of symbol representation is the associations between orthographic symbols and speech sounds, known as grapheme–phoneme correspondence. To date, there has been little evidence that animals can learn this form of symbolic representation. Here, we evaluated whether an Umbrella cockatoo (Cacatua alba) can learn letter-speech correspondence using (...) English words. The bird-participant was trained with phonics instruction and then tested on pairs of index cards while the experimenter spoke the word. The words were unknown to the bird and the experimenter was blinded to the correct card position. The cockatoo’s accuracy (M = 71%) was statistically significant. Further, we found a strong correlation between the bird’s word-identification success and the number of overlapping letters between words, where the more overlapping letters between words, the more likely the cockatoo answered incorrectly. Our results strongly suggest that parrots may have the ability to learn grapheme–phoneme correspondences. (shrink)

Pet-directed speech (PDS) is often produced by humans when addressing dogs. Similar to infant-directed speech, PDS is marked by a relatively higher and more modulated fundamental frequency (f 0) than is adult-directed speech. We tested the prediction that increasing eye size in dogs, one facial feature of neoteny (juvenilisation), would elicit exaggerated prosodic qualities or pet-directed speech. We experimentally manipulated eye size in photographs of twelve dog breeds by −15%, +15% and +30%. We first showed that dogs with larger eyes (...) were indeed perceived as younger. We then recorded men and women speaking towards these photographs, who also rated these images for cuteness. Linear mixed-effects models demonstrated that increasing eye size by 15% significantly increased pitch range (f 0 range) and variability (f 0CV) among women only. Cuteness ratings did not vary with eye size, due to a possible ceiling effect across eye sizes. Our results offer preliminary evidence that large eyes can elicit pet-directed speech and suggest that PDS may be modulated by perceived juvenility rather than cuteness. We discuss these findings in the context of inter-species vocal communication. (shrink)

Adult-infant early dyadic interactions have been extensively explored by developmental psychologists. Around the age of 2 months, infants already demonstrate complex, delicate and very sensitive behaviors that seem to express their ability to interact and share emotions with their caregivers. This paper presents 3 pilot studies of parent-infant dyadic interaction in various set-ups. The first two present longitudinal data collected on two infants aged between 1 and 6 months and their mothers. We analyzed the development of coordination between them, at (...) the motor and at the vocal level. The 3rd pilot study aims to explore interpersonal coordination in both vocal behavior and motor activity for one infant and his mother at 2, 4 and 6 months. These pilot studies however leave a number of questions open concerning developmental changes and infants’ progressive mastery of interaction. We identify areas worth examining and try to tease out specific issues that may help develop new methodological pathways for the study of early naturalistic social interaction. We assume that a continuous, rather than discrete, approach would better capture the changes taking place in the various communicative modalities, while also displaying each dyad’s specificity and the narrative dimension of social engagement between infants and caregivers.

Cetaceans show high cognitive abilities and strong social bonds. Their primary sensory modality to communicate and sense the environment is acoustics. Research on their echolocation and social vocalizations typically uses visual and tactile systems adapted from research on primates or birds. Such research would benefit from a purely acoustic communication system to better match their natural capabilities. We argue that a full duplex system, in which signals can flow in both directions simultaneously is essential for communication research. We designed and (...) implemented a full duplex system to acoustically interact with cetaceans in the wild, featuring digital echo-suppression. We pilot tested the system in Arctic Norway and achieved an echo suppression of 18 dB. We discuss the limiting factors and how to improve the echo suppression further. The system enabled vocal interaction with the underwater acoustic scene by allowing experimenters to listen while producing sounds. We describe our motivations, then present our pilot deployment and give examples of initial explorative attempts to vocally interact with wild orcas and humpback whales. (shrink)

Human–Human and Human–Robot Interaction are known to be influenced by a variety of modalities and parameters. Nevertheless, it remains a challenge to anticipate how a given mobile robot’s navigation and appearance will impact how it is perceived by humans. Drawing a parallel with vocal prosody, we introduce the notion of movement prosody, which encompasses spatio-temporal and appearance dimensions which are involved in a person’s perceptual experience of interacting with a mobile robot. We design a novel robot motion corpus, encompassing variables (...) related to the kinematics, gaze, and appearance of the robot, which we hypothesize are involved in movement prosody. Initial results of three perception experiments suggest that these variables have significant influences on participants’ perceptions of robot socio-affects and physical attributes. (shrink)
