We examine whether trust in smart systems is generated analogously to humans and the automation level of affects trustworthiness acceptability those systems.Trust an important factor when considering technology. As shared goals lead social trust, intelligent machines tend be treated like humans, authors expected that driving would also increased adaptive cruise control (ACC) systems.In experiment, participants (N = 57) were presented with descriptions three ACCs different levels described as...

Earlier theorizing suggested that an (artificial) agent combines persuasive strategies will be more persuasive. Therefore, the current research investigated whether a robot uses two is than only one. Two crucial humans use in face-to-face persuasion are gazing and gestures, therefore we studied combined individual contribution of these (gestures gazing) on persuasiveness storytelling robot. A told classical story about consequences lying to forty-eight participants, was programmed...

We explored the possibility of a general brightness bias: brighter pictures are evaluated more positively, while darker negatively. In Study 1 we found that positive than negative in two affective picture databases (the IAPS and GAPED). 2 revealed because researchers select on extremity their rating without controlling for differences, used conditions experiments were average those conditions. Going beyond correlational support our hypothesis, Studies 3 4 showed versions neutral positively...

Anthropomorphism is generally defined as the attribution of human-like characteristics to social robots and other non-human objects. We argue that different researchers have interpretations this concept, leading measuring instruments focus on subsets characteristics. In current paper, we discuss these explore a new method for anthropomorphism, based Rasch model. The aim work map anthropomorphism range one-dimensional scale. scale's validity sensitivity were tested by comparing it with two...

Abstract In the last years, there have been rapid developments in social robotics, which bring about prospect of their application as persuasive robots to support behavior change. order guide related and pave way for adoption, it is important understand factors that influence acceptance agents. This study extends technology model by including measures responses. The responses include trusting belief, compliance, liking, psychological reactance. Using Wizard Oz method, a laboratory experiment...

This research views dispositional inference as a process whereby perceivers integrate multiple inferences about target person's motives and traits. The findings suggest that although perceived may stimulate extra attributional processing (S. Fein, 1996), the content of inferred motive is important well. Perceivers learned situational forces implying person had free choice, no or an ulterior for helpful behavior. Inferences target's helpfulness differed depending on whether behavior was...

In the near future, robotic agents might employ persuasion to influence people’s behavior or attitudes, just as human do in many situations. People can comply with these requests, but, people also experience psychological reactance, which may lead complete opposite of proposed behavior. this study we are interested social nature reactance. Social agency theory proposes that more cues a interaction. We argue holds for Therefore, expect positive relationship between level source persuasive...

Objective: We examined whether participants would trust an agent that was similar to them more than dissimilar them. Background: Trust is important psychological factor determining the acceptance of smart systems. Because systems tend be treated like humans, and similarity has been shown increase in we expected a virtual agent. Methods: In driving simulator experiment, ( N = 111) were presented with either or not. This functioned as their driver simulator, this measured. Furthermore,...

Research in the field of social robotics suggests that enhancing cues robots can elicit more responses users. It is however not clear how users respond socially to persuasive and whether such reactions will be pronounced when feature interactive cues. In current research, we examine towards attempts provided by a robot featuring different numbers A laboratory experiment assessed participants' psychological reactance, liking, trusting beliefs compliance toward either presented with: no...

Measurement of users' perception and visual behaviors to anthropomorphic design cues chatbots can improve our understanding potentially optimize chatbot design. However, as two typical basic features, how appearances conversational styles jointly affect remains unclear. Therefore, this study conducted an eye-tracking experiment explore behaviors. Results indicate that human-like increased chatbots' social presence, trust in chatbots, satisfaction with chatbots. In contrast, on behaviors,...

In this paper we explore the persuasive effects of social feedback, as provided by an embodied agent, on behavioral change. a lab setting, two experiments were conducted in which participants had opportunity to conserve energy while carrying out washing tasks with simulated machine. The tested effect positive and negative feedback compared these more widely used factual feedback. Results both studies indicate that has stronger than (Experiment 1) factual-evaluative 2). addition, valence was...

Abstract As witnessed in several behavioural studies, a complex relationship exists between people’s cultural background and their general acceptance towards robots. However, very few studies have investigated whether robot’s original language gesture based on certain culture an impact the people of different cultures. The purpose this work is to provide experimental evidence which supports idea that humans may accept more easily robot can adapt specific culture. Indeed, improving reducing...

Current self-report medication adherence measures often provide heavily skewed results with limited variance, suggesting that most participants are highly adherent. This contrasts findings from objective measures. We argue one of the main limitations these is range covered by behaviors assessed. That is, items do not match people perform, resulting in a ceiling effect. In this paper, we present new self-reported scale based on Rasch model approach (the ProMAS), which covers wide behaviors....
