A Conceptual Framework to Improve the Symbol Implementation of 4D Printing Communication between Designers and Engineers

This research investigates the communication barriers between designers and engineers in designing 4D Printing parts. We have proposed a conceptual design framework for 4D Printing symbols as the communication tool. Then, we have recruited sixty-fifty designers and engineers who participated in our online experiments. The focus of the online survey is to find out how designers and engineers understand reciprocal communication by using the proposed symbols. Our results showed that 85% of participants could understand the 4D Printing symbols correctly. The study concludes that using the conceptual framework can help designers and engineers communicate 4D Printing element information and stimulate design ideas effectively.

The more, the better? Effects of transparency tools and moderators on the perceived credibility of news articles

Transparency is often discussed as a way to increase the public’s perception of journalism. While its adoption by newsrooms is relatively well studied, only a few studies have investigated its effects on news users’ credibility judgments. We build on research about transparency effects and report the results of two online experiments (total N = 2262), one with a local and one with a national newspaper frame. Our results suggest that transparency does not affect the perceived message and source credibility newspaper articles and that moderating factors such as cognitive involvement and media skepticism are more important predictors of credibility assessments.

Bringing Home Baby Euclid: Testing Infants’ Basic Shape Discrimination Online

Online developmental psychology studies are still in their infancy, but their role is newly urgent in the light of the COVID-19 pandemic and the suspension of in-person research. Are online studies with infants a suitable stand-in for laboratory-based studies? Across two unmonitored online experiments using a change-detection looking-time paradigm with 96 7-month-old infants, we found that infants did not exhibit measurable sensitivities to the basic shape information that distinguishes between 2D geometric forms, as had been observed in previous laboratory experiments. Moreover, while infants were distracted in our online experiments, such distraction was nevertheless not a reliable predictor of their ability to discriminate shape information. Our findings suggest that the change-detection paradigm may not elicit infants’ shape discrimination abilities when stimuli are presented on small, personal computer screens because infants may not perceive two discrete events with only one event displaying uniquely changing information that draws their attention. Some developmental paradigms used with infants, even those that seem well-suited to the constraints and goals of online data collection, may thus not yield results consistent with the laboratory results that rely on highly controlled settings and specialized equipment, such as large screens. As developmental researchers continue to adapt laboratory-based methods to online contexts, testing those methods online is a necessary first step in creating robust tools and expanding the space of inquiry for developmental science conducted online.

Collateral Damage: The Relationship Between High-Salience Events and Variation in Racial Discrimination

To what extent are individual or organizational biases affected by racially salient events? We propose that acts of discrimination and the individual biases that undergird them are sensitive to high-salience events and will oscillate with the salience of the focal attribute. In short, that the propensity to discriminate reflects both individual and environmental differences, and therefore a given person may become more prone to discriminate in the aftermath of a high-salience event. We test our hypothesis in three online experiments that examine how varying the salience of race affects the evaluation of in-group or out-group founders. We find that respondents evaluate their in-group members more favorably, and out-group members less favorably, when exposed to a high-salience event, which translates into a significant disadvantage for the minority (African American) group. We complement these studies with an assessment of how police shootings affect fundraising outcomes on Kickstarter to confirm the external validity of our findings. Together, these studies indicate that racially salient events depress the quality evaluations and success odds of African American entrepreneurs relative to others. Hence, discrimination levels can be affected by salient yet unrelated events, and such events are consequential for the economic fortunes of individuals belonging to minority and disadvantaged groups.

The Intention to Conceal Does Not Always Affect Time Perception

The display duration of stimuli is overestimated due to the increase in phasic arousal induced by the stimuli or high levels of background arousal. A previous study demonstrated that display duration of items (2 s) was overestimated when a participant attempted to conceal one of the items so as not to be detected in the concealed information test (CIT). As the time perception remained the same between the item to be concealed and the other items, the overestimation was thought to be due to the high level of background arousal under the conceal condition. Duration of 2 s may be too long to examine the phasic arousal effect induced by the concealed item. The present study conducted three online experiments with shorter durations, that is, each of three items was presented with duration of 1, 0.5, and 2 s in Experiments 1, 2, and 3, respectively. The participants were instructed to conceal one of the three items under the conceal condition and did not conceal any item in the innocent condition. The difference in time perception between the conceal and innocent conditions or between items under the conceal condition was observed in none of the three experiments. The result indicates that temporal overestimation does not occur when a participant is only concealing an object. Rather, temporal overestimation would occur only when the level of background arousal is amplified by the concealment.

Agents’ moral character shapes people’s moral evaluations of accidental harm transgressions

Previous research has documented that judging someone responsible for an accident mainly relies on considerations about the outcome endured by the victim and the intention to cause harm. Yet, we question how these two factors may be influenced by the morality ascribed to the agent, independently of the action itself. In two online experiments, we determined whether information about the moral character of agents influenced moral judgment of accidental harm. Participants were presented with short narratives depicting accidental harm scenarios and were asked to report their judgment of the perpetrator. In experiment 1 (N = 337), we manipulated the perpetrator’s morality and warmth orthogonally. In experiment 2 (N = 271), we focused on morality and simultaneously manipulated the perpetrator’s and victim’s moral character. In both experiments, we found that the perpetrator’s moral character influenced judgments of acceptability, blame, punishment and compensation. Participants were more forgiving toward perpetrators of high morality relative to low morality, and the effect of the moral character was greater than the effect of warmth (experiment 1). The victim’s moral character also influenced moral judgments but to a lesser extent than that of the perpetrator and did not interact with the moral character of the perpetrator (experiment 2). Participants were harsher toward the perpetrator when the victim was described as having high morality as compared to low morality, and compensation for the victim also aligned with the victim’s morality. These results show that third-party moral judgment is influenced by the moral character of agents despite information implying that harm was unintended.

Hitting Net-Zero Without Stopping Flying: Increasing Air Travelers’ Likelihood to Opt-in to Voluntary Carbon Offsetting

Voluntary carbon offset (VCO) programs give air travelers opportunities to neutralize their carbon footprint. Despite its potential, few existing studies have explained how to present VCOs that can effectively appeal to the sensibilities of travelers in different conditions. We designed three online experiments with strategies to motivate travelers to opt-in. We found travelers who receive concrete messages that emphasize specific actions are more likely to opt-in to VCOs when flying in the near future. In contrast, travelers receiving abstract messages that emphasize general initiatives are more likely to opt-in to VCOs when flying in the distant future. When travelers are allowed to choose their preferred carbon offset method, they are more likely to opt in, especially when they receive concrete messages that indicate specific actions but not general initiatives. These findings contribute to the aviation carbon offset literature and offer useful new insights for airline companies.
