The moral foreign language effect is stable across presentation modalities
YesPeoplesâ judgments and decisions often change when made in their foreign language. Existing
research testing this foreign language effect has predominantly used text-based stimuli with little
research focusing on the impact of listening to audio stimuli on the effect. The only existing study on
this topic found shifts in peopleâs moral decisions only in the audio modality. Firstly, by reanalyzing
the data from this previous study and by collecting data in an additional experiment, we found no
consistent effects of using foreign language on moral judgments. Secondly, in both datasets we
found no significant language by modality interaction. Overall, our results highlight the need for
more robust testing of the foreign language effect, and its boundary conditions. However, modality
of presentation does not appear to be a candidate for explaining its variability. Data and materials for
this experiment are available at https://osf.io/qbjxn/
The experimental psychology of moral enhancement: We should if we could, but we can't
YesIn this chapter we will review experimental evidence related to pharmacological moral enhancement. Firstly, we will present our recent study in which we found that a drug called propranolol could change moral judgements. Further research, which also investigated this, found similar results. Secondly, we will discuss the limitations of such approaches, when it comes to the idea of general âhuman enhancementâ. Whilst promising effects on certain moral concepts might be beneficial to the development of theoretical moral psychology, enhancement of human moral behaviour in general â to our current understanding â has more side-effects than intended effects, making it potentially harmful. We give an overview of misconceptions when taking experimental findings beyond the laboratory and discuss the problems and solutions associated with the psychological assessment of moral behaviour. Indeed, how is morality âmeasuredâ in psychology, and are those measures reliable

Socratic Questionnaires
When experimental participants are given the chance to reflect and revise their initial judgments in a dynamic conversational context, do their responses to philosophical scenarios differ from responses to those same scenarios presented in a traditional static survey? In three experiments comparing responses given in conversational contexts with responses to traditional static surveys, we find no consistent evidence that responses differ in these different formats. This aligns with recent findings that various manipulations of reflectiveness have no effect on participantsâ judgments about philosophical scenarios. Although we did not find a consistent quantitative effect of format (conversation vs. static survey), conversational experiments still provide qualitative insights into debates about how participants are understanding (or misunderstanding) the scenarios they read in experimental studies, whether they are replacing difficult questions with questions that are more easily answered, and how participants are imagining the scenarios they read in ways that differ from what is explicitly stated by experimenters. We argue that conversational experimentsâ"Socratic questionnaires"âhelp show what is going on âunder the hoodâ of traditional survey designs in the experimental investigation of philosophical questions

An empirical investigation of intuitions about uptake
Since Austinâs introduction of the locutionary-illocutionary-perlocutionary distinction, it has been a matter of debate within speech act theory whether illocutionary acts like promising, warning, refusing and telling require audience âuptakeâ in order to be performed. Philosophers on different sides of this debate have tried to support their positions by appealing to hypothetical scenarios, designed to elicit intuitive judgements about the role of uptake. However, philosophersâ intuitions appeared to remain deadlocked, while laypeopleâs intuitions have not yet been probed. To begin rectifying that, we ran two experiments probing lay intuitions about the implications of uptake failure. Overall, we found that participantsâ responses were skewed towards agreement that speech acts were performed, despite the lack of uptake. There were, however, significant differences across the four different speech act types we investigated (with the highest levels of agreement found for refusing, followed by warning, then telling, and finally promising). We also obtained evidence of complex effects relating to the (high or low) stakes involved in the scenarios. While this study only represents an initial exploration of intuitions about uptake, our results form a basis for further research into their nature and significance, across a range of speech acts, scenarios, and experimental designs

Simulating Moral Actions: An Investigation of Personal Force in Virtual Moral Dilemmas
Advances in Virtual Reality (VR) technologies allow the investigation of simulated moral actions in visually immersive environments. Using a robotic manipulandum and an interactive sculpture, we now also incorporate realistic haptic feedback into virtual moral simulations. In two experiments, we found that participants responded with greater utilitarian actions in virtual and haptic environments when compared to traditional questionnaire assessments of moral judgments. In experiment one, when incorporating a robotic manipulandum, we found that the physical power of simulated utilitarian responses (calculated as the product of force and speed) was predicted by individual levels of psychopathy. In experiment two, which integrated an interactive and lifelike sculpture of a human into a VR simulation, greater utilitarian actions continued to be observed. Together, these results support a disparity between simulated moral action and moral judgment. Overall this research combines state-of-the-art virtual reality, robotic movement simulations, and realistic human sculptures, to enhance moral paradigms that are often contextually impoverished. As such, this combination provides a better assessment of simulated moral action, and illustrates the embodied nature of morally-relevant actions
Donât mind milk? The role of animal suffering, speciesism, and guilt in the denial of mind and moral status of dairy cows
Reminding meat-eaters that animals are being harmed for meat production, elicits psychological tension about meat consumption. Individuals deal with this tension by either reducing or stopping meat consumption or by denying the mind of food animals, thereby lowering the moral status of animals. It is currently unclear whether similar reactions occur when considering dairy consumption. In a preregistered experiment (N = 345 animal product consumers), we manipulated perceived harm levels inflicted upon dairy cows (higher versus lower) to investigate peopleâs use of dairy-related cognitive dissonance reduction strategies. Participants in the high (vs low) harm condition felt more guilty which in turn, was associated with a) lower mind attribution and moral concern for the cow and b) greater intentions to reduce or stop dairy consumption. These effects were especially pronounced for participants higher in speciesism, while among those lower in speciesism, the effects were weaker (on guilt and intentions to change dairy consumption) or non-significant (on mind attribution, moral concern). The findings demonstrate that increased awareness of animal harm in dairy farms, elicits guilt and dissonance reduction reactions similar to meat-related dissonance reactions. Evidence of dairy-related cognitive dissonance highlights the need for a greater research focus on the consumption of animal products other than meat
Muon-spin relaxation investigation of magnetic bistability in a crystalline organic radical compound
We present the results of a muon-spin relaxation (SR) investigation
of the crystalline organic radical compound
4-(2-benzimidazolyl)-1,2,3,5-dithiadiazolyl (HbimDTDA), in which we demonstrate
the hysteretic magnetic switching of the system that takes place at caused by a structural phase transition. Muon-site analysis
using electronic structure calculations suggests a range of candidate muon
stopping sites. The sites are numerous and similar in energy but,
significantly, differ between the two structural phases of the material.
Despite the difference in the sites, the muon remains a faithful probe of the
transition, revealing a dynamically-fluctuating magnetically disordered state
in the low-temperature structural phase. In contrast, in the high temperature
phase the relaxation is caused by static nuclear moments, with rapid electronic
dynamics being motionally narrowed from the muon spectra
Moral psychology of nursing robots : Exploring the role of robots in dilemmas of patient autonomy
Artificial intelligences (AIs) are widely used in tasks ranging from transportation to healthcare and military, but it is not yet known how people prefer them to act in ethically difficult situations. In five studies (an anthropological field study, n = 30, and four experiments, total n = 2150), we presented people with vignettes where a human or an advanced robot nurse is ordered by a doctor to forcefully medicate an unwilling patient. Participants were more accepting of a human nurse's than a robot nurse's forceful medication of the patient, and more accepting of (human or robot) nurses who respected patient autonomy rather than those that followed the orders to forcefully medicate (Study 2). The findings were robust against the perceived competence of the robot (Study 3), moral luck (whether the patient lived or died afterwards; Study 4), and command chain effects (Study 5; fully automated supervision or not). Thus, people prefer robots capable of disobeying orders in favour of abstract moral principles like valuing personal autonomy. Our studies fit in a new era in research, where moral psychological phenomena no longer reflect only interactions between people, but between people and autonomous AIs.Peer reviewe
Design catalogue for eco-engineering of coastal artificial structures:a multifunctional approach for stakeholders and end-users
Coastal urbanisation, energy extraction, food production, shipping and transportation have led to the global proliferation of artificial structures within the coastal and marine environments (sensu âocean sprawlâ), with subsequent loss of natural habitats and biodiversity. To mitigate and compensate impacts of ocean sprawl, the practice of ecoengineering of artificial structures has been developed over the past decade. Eco-engineering aims to create sustainable ecosystems that integrate human society with the natural environment for the benefit of both. The science of eco-engineering has grown markedly, yet synthesis of research into a user-friendly and practitioner-focused format is lacking. Feedback from stakeholders has repeatedly stated that a âphoto user guideâ or âmanualâ covering the range of eco-engineering options available for artificial structures would be beneficial. However, a detailed and structured âuser guideâ for eco-engineering in coastal and marine environments is not yet possible; therefore we present an accessible review and catalogue of trialled eco-engineering options and a summary of guidance for a range of
different structures tailored for stakeholders and end-users as the first step towards a structured manual. This work
can thus serve as a potential template for future eco-engineering guides. Here we provide suggestions for potential eco-engineering designs to enhance biodiversity and ecosystem functioning and services of coastal artificial structures with the following structures covered: (1) rock revetment, breakwaters and groynes composed of armour stones or concrete units; (2) vertical and sloping seawalls; (3) over-water structures (i.e., piers) and associated support structures; and (4) tidal river walls
