Higginbotham argued that certain linguistic items of English, when used in indirect discourse, necessarily trigger first-personal interpretations. They are: the emphatic reflexive pronoun and the controlled understood subject, represented as PRO. PRO is special, in this respect, due to its imposing obligatory control effects between the main clause and its subordinates ). Folescu & Higginbotham, in addition, argued that in Romanian, a language whose grammar doesn’t assign a prominent role to PRO, de se triggers are correlated with (...) the subjunctive mood of certain verbs. That paper, however, didn’t account for the grammatical diversity of the reports that display immunity to error through misidentification in Romanian: some of these reports are expressed by using de se triggers; others are not. Their IEM, moreover, is not systematically lexically controlled by the verbs, via their theta-roles; it is, rather, determined by the meaning of the verbs in question. Given the data from Romanian, I will argue, the phenomenon of IEM cannot be fully explained starting either from the syntactical or the lexical structure of a language. (shrink)

This book addresses a dilemma concerning freedom and moral obligation (obligation, right and wrong). If determinism is true, then no one has control over one's actions. If indeterminism is true, then no one has control over their actions. But it is morally obligatory, right or wrong for one to perform some action only if one has control over it. Hence, no one ever performs an action that is morally obligatory, right or wrong. The author defends (...) the view that this dilemma can be evaded but not in a way traditional compatibilists about freedom and moral responsibility will find congenial. For moral obligation is indeed incompatible with determinism but not with indeterminism. He concludes with an argument to the effect that, if determinism is true and no action is morally obligatory, right or wrong, then our world would be considerably morally impoverished as several sorts of moral appraisal would be unjustified.

This paper presents a refinement of a result by Conidis, who proved that there is a real $X$ of effective packing dimension $0\lt \alpha\lt 1$ which cannot compute any real of effective packing dimension $1$. The original construction was carried out below $\emptyset''$, and this paper’s result is an improvement in the effectiveness of the argument, constructing such an $X$ by a limit-computable approximation to get $X\leq_{T}\emptyset'$.

Choice reaction tasks are performed faster when stimulus location corresponds to response location. This spatial stimulus–response compatibility effect affects performance at the level of action planning and execution. However, when response selection is completed before movement initiation, the Simon effect arises only at the planning level. The aim of this study was to ascertain whether when a precocious response selection is requested, the Simon effect can be detected on the kinematics characterizing the online control phase of a non-ballistic movement. (...) Participants were presented with red or green colored squares, which could appear on the right, left, above, or below a central cross. Depending on the square's color, participants had to release one of two buttons, then reach toward and press a corresponding lateral pad. We found evidence of the Simon effect on both action planning and on-line control. Moreover, the investigation of response conflict at the level of previous trials, a factor that might determine interference at the level of the current response, revealed a conflict adaptation process across trials. Results are discussed in terms of current theories concerned with the Simon effect and the distinction between action planning and control. (shrink)

The aim of our experiment was to analyse the effect of the emotional valence (positive, negative, or neutral) on true and false recognition, matching the arousal, frequency, concreteness, and associative strength of the study and recognition words. Fifty younger adults and 46 healthy older adults performed three study tasks (with words of different valence: positive, negative, neutral) and their corresponding recognition tests. Two weeks later, they performed the three recognition tests again. The results show that words with a negative valence (...) produced less true recognition and less false recognition than words with a positive or neutral valence, in both younger and older adults, on the immediate recognition test. This pattern of results was also found in the younger adults on the delayed recognition test, whereas in the older participants, these differences disappeared. Thus, when arousal is controlled, both younger and older adults tend to recognise negative information worse than positive or neutral information, but they also commit fewer errors. Results would suggest that the greater arousal commonly associated with negative stimuli, rather than their own valence, could explain some of the contradictory results found in the literature.

In recent years, the problem of environmental pollution has become more and more serious, and environmental pollution has become a topic of concern. PM2.5, PM10, hazy weather, and other words about environmental pollution have become hot words and topics for the media and the public to talk about, and environmental pollution control is called for by the media and the public. This reflects the rapid development of economy and the obvious changes in people’s living standards, and people have higher (...) requirements and aspirations for their lives and the environment they live in, and their awareness of environmental protection is getting stronger and stronger; however, it also reflects that the rapid development of the economy comes at the cost of damaging the environment. This paper analyzes the current situation and governance dilemma of rural environment by means of field research from dynamic portfolio evaluation theory, explains the problems and causes of environmental pollution management under the requirement of polycentric governance, and proposes countermeasures to solve the problem of environmental pollution management in county. The paper aims to analyze the current state of environmental pollution in rural areas through literature review, villagers’ field interviews, and field research and to explain the application of polycentric governance to rural environmental pollution management in county in the region.

BACKGROUND -/- The importance of ontologies in the biomedical domain is generally recognized. However, their quality is often too poor for large-scale use in critical applications, at least partially due to insufficient training of ontology developers. -/- OBJECTIVE -/- To show the efficacy of guideline-based ontology development training on the performance of ontology developers. The hypothesis was that students who received training on top-level ontologies and design patterns perform better than those who only received training in the basic principles of (...) formal ontology engineering. -/- METHODS -/- A curriculum was implemented based on a guideline for ontology design. A randomized controlled trial on the efficacy of this curriculum was performed with 24 students from bioinformatics and related fields. After joint training on the fundamentals of ontology development the students were randomly allocated to two groups. During the intervention, each group received training on different topics in ontology development. In the assessment phase, all students were asked to solve modeling problems on topics taught differentially in the intervention phase. Primary outcome was the similarity of the students’ ontology artefacts compared with gold standard ontologies developed by the authors before the experiment; secondary outcome was the intra-group similarity of group members’ ontologies. -/- RESULTS -/- The experiment showed no significant effect of the guideline-based training on the performance of ontology developers (a) the ontologies developed after specific training were only slightly but not significantly closer to the gold standard ontologies than the ontologies developed without prior specific training; (b) although significant differences for certain ontologies were detected, the intra-group similarity was not consistently influenced in one direction by the differential training. -/- CONCLUSION -/- Methodologically limited, this study cannot be interpreted as a general failure of a guideline-based approach to ontology development. Further research is needed to increase insight into whether specific development guidelines and practices in ontology design are effective. (shrink)

This paper presents novel data regarding the logophoric pronoun in Ewe. We show that, contrary to what had been assumed in the absence of the necessary fieldwork, Ewe logophors are not obligatorily interpreted de se. We discuss the prima facie rather surprising nature of this discovery given the assumptions that de se construals arise via binding of the pronoun by an abstraction operator in the left periphery of the clausal complement of an attitude predicate, and that logophors are elements that (...) are obligatorily bound by such abstractors. We show that this approach can be reconciled with these facts given the additional assumption that elements that are ‘de se’ bound can interact with the concept generator variables posited by Percus and Sauerland to derive de re interpretations of embedded nominals. The proposed set-up has consequences for our understanding of puzzles raised by Heim and Sharvit concerning binding-theoretic effects with de re elements, and for the derivation of the obligatorily de se interpretation of controlled PRO.

What kinds of evidence reliably support predictions of effectiveness for health and social care interventions? There is increasing reliance, not only for health care policy and practice but also for more general social and economic policy deliberation, on evidence that comes from studies whose basic logic is that of JS Mill's method of difference. These include randomized controlled trials, case–control studies, cohort studies, and some uses of causal Bayes nets and counterfactual-licensing models like ones commonly developed in econometrics. The (...) topic of this paper is the 'external validity' of causal conclusions from these kinds of studies. We shall argue two claims. Claim, negative: external validity is the wrong idea; claim, positive: 'capacities' are almost always the right idea, if there is a right idea to be had. If we are right about these claims, it makes big problems for policy decisions. Many advice guides for grading policy predictions give top grades to a proposed policy if it has two good Mill's-method-of difference studies that support it. But if capacities are to serve as the conduit for support from a method-of-difference study to an effectiveness prediction, much more evidence, and much different in kind, is required. We will illustrate the complexities involved with the case of multisystemic therapy, an internationally adopted intervention to try to diminish antisocial behaviour in young people. (shrink)

Background: Ideas always have and always will change the world; with ideas-engagement enabling individuals to become more knowledgeable, better able to make good decisions and better positioned to re-align their values in response to new progressive norms and beliefs. Given these potential benefits, of primary interest is how citizens can be most effectively encouraged to engage with new ideas. Methods: With this study we test the efficacy of two approaches designed to enhance citizen’s perceptions regarding the value of ideas-engagement. Specifically, (...) we recontextualise a previously undertaken small-scale randomised control trial designed to stimulate states of either curiosity or pragmatic prospection amongst two randomly allocated groups of respondents. Our target variables involve the importance respondents attribute to staying up to date, as well as to four related attitudinal variables. Our target audience is the voting age population of England. Results: 515 participants took part in the experiment, with 269 receiving the curiosity stimulating intervention and 246, the prospection intervention. Our findings suggest that, by the end of four weeks, only the intervention designed to promote pragmatic prospection had significantly impacted on the importance respondents attribute to staying up to date. It also positively impacted the value- scores for one of the secondary attitudinal variables (relating to the importance of supporting physical and mental-health). Conclusions: While this study provides useful insight regarding ideas-engagement, further work is needed. In particular, future studies will require a larger sample, so as to ascertain the impact of these approaches on ‘ideas refusers’. Also required is the inclusion of a control group to provide a definitive counter factual. Furthermore, since positive changes in attitudes towards ideas- engagement also ideally leads to changes in behaviours, questions are also needed to examine the sources of ideas respondents subsequently engage with (or not) as a result of these interventions.

This multi-centre research investigates the effects of dance movement therapy (DMT) on participants diagnosed with depression. In total, 109 persons participated in the study in various locations in Finland. The participants were 39 years old, on average (range = 18–64 years), and most were female (96%). All participants received treatment as usual (TAU). They were randomised into DMT+TAU (n = 52) or TAU-only (n = 57). The participants in the DMT + TAU group were offered 20 DMT sessions twice (...) a week for 10 weeks in addition to standard care. The measurement points included pre-treatment measurement at the baseline, post-treatment measurement at the end of the intervention, and a follow-up measurement 3 months afterward. The observed effects of the intervention among participants in the DMT+TAU group were a greater reduction in depression (BDI-I) and in indicators of physical and psychological distress (CORE-OM and SCL-90) in comparison to the participants who received TAU-only. At the 3-month follow-up, the corrected between-group effect sizes (ES) were medium and in favour of the DMT+TAU group (d = 0.60–0.72). These results are in line with the increasing number of research studies showing the benefits of DMT intervention among participants with depression, and these results indicate that DMT may improve the effectiveness of standard care.

Fundamental movement skill proficiency does not develop solely due to maturation, but also via diverse perceptual-motor experiences across childhood. Practicing gymnastics has been shown to improve postural control. The purpose of the present study was to examine potential changes to postural control of children following a course of educational gymnastics. Two groups of children both completed 20 × 45-min physical education lessons; one group completed educational gymnastics lessons in school delivered by a professional coach, the other group completed (...) their typical PE classes. Unipedal balancing performance was assessed by calculating the percentage of successful trials made. Postural sway dynamics were explored by calculating center-of-pressure sample entropy, 95% ellipse sway area and sway velocity. Measurements were taken before the lessons began and immediately after the lessons were completed. The gymnastics group performed better than the typical PE group at unipedal balancing. Females outperformed males in both groups. Males made different changes to postural control compared to females across 3 months. Educational gymnastics enabled children in a critical period of development to make more rapid improvements to postural performance and control. Novel movement experiences, like those offered by educational gymnastics, may have a positive influence on postural control and importantly, physical literacy. Future work should examine how sex effects the development of postural control strategies in young children. (shrink)

Background Ethical decision‑making and behavior of nurses are major factors that can affect the quality of nursing care. Moral development of nurses to making better ethical decision-making is an essential element for managing the care process. The main aim of this study was to examine and comparison the effect of training in ethical decision-making through lectures and group discussions on nurses’ moral reasoning, moral distress and moral sensitivity. Methods In this randomized clinical trial study with a pre- and post-test design, (...) 66 nurses with moral reasoning scores lower than the average of the community were randomly assigned into three equal groups (n = 22) including two experimental groups and one control group. Ethical decision-making training to experimental groups was provided through the lectures and group discussions. While, the control group did not receive any training. Data were collected using sociodemographic questionnaire, the nursing dilemma test (NDT), the moral distress scale (MDS) and the moral sensitivity questionnaire (MSQ). Unadjusted and adjusted binary logistic regression analysis was reported using the odds ratio (OR) and 95% confidence intervals. Results Adjusted regression analysis showed that the probability of increasing the nursing principle thinking (NPT) score through discussion training was significantly higher than lecture (OR: 13.078, 95% CI: 3.238–15.954, P = 0.008), as well as lecture (OR: 14.329, 95% CI: 16.171–2.005, P < 0.001) and discussion groups compared to the control group (OR: 18.01, 95% CI: 22.15–5.834, P < 0.001). The possibility of increasing moral sensitivity score through discussion training was significantly higher than lecture (OR: 10.874, 95%CI: 6.043–12.886, P = 0.005) and control group (OR: 13.077, 95%CI: 8.454–16.774, P = 0.002). Moreover, the moral distress score was significantly reduced only in the trained group compared to the control, and no significant difference was observed between the experimental groups; lecture group vs. control group (OR: 0.105, 95% CI: 0.015–0.717, P = 0.021) and discussion group vs. control group (OR: 0.089, 95% CI: 0.015–0.547, P = 0.009). Conclusions The results of this study indicate that ethical decision-making training is effective on empowerment of ethical reasoning. Whereas the group discussion was also effective on increasing the ethical sensitivity, it is recommended the training plan provided in this study to be held as workshop for all nurses in health and treatment centers and placed in curricular plan of nursing students.

The article presents two studies based on the assumption that the effectiveness of cognitive control depends on the subject’s type of emotional state. Inhibitory control is taken into account, as the basic determinant of the antisaccade reactions and the emotional Stroop effect. The studies deal with differentiation of emotions on the basis of their origin: automatic vs. reflective. According to the main assumption, automatic emotions are diffusive, and decrease the effectiveness of cognitive control. The hypothesis predicted that (...) performance level of both the Antisaccade Task and the Emotional Stroop Test would be lower in the automaticemotion eliciting condition than in the reflective-emotion eliciting condition. In two experimental studies, positive and negative emotions were elicited. The results support the predictions, regardless of the valence of emotions. (shrink)

Electroencephalography-neurofeedback has become a valuable tool in the field of psychology, e.g., to improve cognitive function. Nevertheless, a large percentage of NF users seem to be unable to control their own brain activation. Therefore, the aim of this study was to examine whether a different kind of visual feedback could positively influence NF performance after one training session. Virtual reality seems to have beneficial training effects and has already been reported to increase motivational training aspects. In the present (...) study, we tested 61 young healthy adults to investigate, whether 3D VR-based NF training has a more beneficial effect on the sensorimotor rhythm power increase than a mere 2D conventional NF paradigm. In the 3D group, participants had to roll a ball along a predefined path in an immersive virtual environment, whereas the 2D group had to increase the height of a bar. Both paradigms were presented using VR goggles. Participants completed one baseline and six feedback runs with 3 min each, in which they should try to increase SMR power over Cz. Half of the participants received real feedback whereas the other half received sham feedback. Participants receiving 3D VR-based feedback showed a linear increase in SMR power over the feedback runs within one training session. This was the case for the real as well as for the sham 3D feedback group and might be related to more general VR-related effects. The 2D group receiving the conventional bar feedback showed no changes in SMR power over the feedback runs. The present study underlines that the visual feedback modality has differential effects on the NF training performance and that 3D VR-based feedback has advantages over conventional 2D feedback.

Stereotype threat is a possible reason for difficulties faced by girls and women in the fields of science, technology, engineering, and mathematics. The threat experienced due to gender can cause elevated worry during performance situations. That is, if the stereotype that women are not as good as men in math becomes salient, this stereotype activation draws women’s attention to task-irrelevant worry caused by the fear of conforming to the negative stereotype. Increased worry can reduce cognitive resources, potentially leading to performance (...) decrements. We argue that such worry is more pronounced immediately after an unrelated self-control demand, which is assumed to temporarily decrease people’s self-control exertion over their attention and stream of thought. This prediction was examined in an experiment conducted with 102 participating university students enrolled in courses in which math plays a crucial role. After the manipulation of self-control capacity, stereotype threat was induced for the female students, but not the male students. Then, the students were asked to report their thoughts during a math performance situation three times. Multiple-group autoregressive path models revealed that when self-control capacity was relatively low, female compared with male students reported more intense worry in the initial two thought protocols. In contrast, in the relatively high self-control capacity condition, female and male students did not differ significantly in their reported worry at any time. These results expand on previous findings, suggesting that threat effects depend on definable situational self-control conditions. (shrink)

The prevalence of cognitive impairment in hemodialysis patients is extremely high. Despite the well-documented benefits of interventions on cognitive function, there is a widespread call for effective strategies that will show the long-term consequences in patients undergoing dialysis. The aim of this research protocol was to investigate the effect of cognitive training combined with physical exercise on cognitive function, physical performance, and frailty indicators in the HD population. We will conduct a randomized controlled intervention trial to examine the effects (...) of a combined non-pharmacological intervention in the form of intradialytic physical exercise and intradialytic cognitive training on cognitive function, indicators of frailty, and physical performance measures in HD patients. The group of patients receiving the study intervention will be compared to the control group receiving standard HD care. The duration of the intervention will be 12 weeks. We will use sensitive instruments to assess cognitive functions. The primary outcome of the study at 12 weeks will be performance on the Alertness subtest of the computerized Test of Attentional Performance. Secondary study outcomes are: Performance in other domains of cognitive function, physical fitness, and assessment of frailty. Study outcomes will be assessed at baseline, immediately after the 12-week intervention, and 6 months after the end of the study without specific further intervention. This study will be among the first to test the synergistic effects of a uniquely designed physical exercise and cognitive training intervention on functional status in HD patients. We believe our results will contribute to dementia prevention research by demonstrating the long-term efficacy of our combined intervention.Clinical Trial Registration:ClinicalTrials.Gov, NCT05150444.

This paper discusses the issues surrounding voluntary action control in terms of two models that have emerged in empirical research into how our human conscious capabilities govern and control voluntary motor actions. A characterization of two aspects of consciousness, phenomenal consciousness and access consciousness, enables us to ask whether effect anticipations need be accessible to consciousness, or whether they can also have an effect on conscious control at an unconscious stage. A review of empirical studies points to (...) the fact that willed actions are influenced by effect anticipations both when they are conscious and when they remain inaccessible to the conscious mind. This suggests that the effects of conscious voluntary actions—in line with the ideomotor principle proposed by William James—are anticipated during the generation of responses. I propose that the integration of perceptual and motor codes arises during action planning. The features of anticipated effects appear to be optionally connected with the features of the actions selected to bring about these effects in the world. (shrink)

SummaryAs part of a prospective controlled study of the psychosomatic effects of elective tubal sterilization, 138 women were questioned about their menstrual functioning before sterilization, and again 6 months and 12 months post-operatively, using standardized interviewing procedures. Adverse changes, including increased menstrual loss, shorter menstrual cycles and greater use of pads or tampons were reported by sterilized subjects at both of the post-operative interviews. Control subjects reported several comparable effects, although adverse changes overall were reported more commonly (...) by sterilized women than by control subjects. However, many of the reported changes appeared to be related to pre-operative contraceptive methods, although consistent increases in use of pads or tampons were found in women who had pre-operatively used neither the pill nor the IUD.

The well-established pattern of Executive expansionism and limited oversight of Executive action in times of terrorism is problematic from the civil libertarian point of view. How to limit such action has been the subject of much scholarship, a large amount of which focuses on perceptions of institutional competence rather than effectiveness. For the authors, the effective control of security-focused state action is to be judged by the extent to which it consists only of action that is necessary and proportionate (...) and thereby strikes an appropriate balance between security exigencies and individual rights. This article, written and structured in dialectic form, presents competing perspectives on effective oversight mechanisms: on the one hand, an extra-constitutionalism perspective, proposing a limited role for the Judiciary and emphasizing the need for legislative and democratic controls; and on the other, an argument for judicial muscularity.

The major argument of this article is that failing to measure what is taking place in treatment and control conditions can lead to scientifically invalid conclusions. It is argued that researchers are ethically responsible for being aware that variables related to the therapist, client, and the therapeutic relationship might play a confounding role when treatment and control conditions are compared. As a consequence, they should either measure these variables or be tentative in their interpretation of their findings.

Selective accessibility mechanisms indicate that anchoring effects are results of selective retrieval of working memory. Neuroimaging studies have revealed that the right dorsolateral prefrontal cortex (DLPFC) is closely related to memory retrieval and performance. However, no research has investigated the effect of changing the cortical excitability in right DLPFC on anchoring effects. Transcranial direct current stimulation (tDCS) can modulate the excitability of the human cerebral cortex, while anodal and cathodal tDCS are postulated to increase or decrease cortical activity, (...) respectively. In this study, we used tDCS to investigate whether effects of increased or decreased right DLPFC excitability influence anchoring effects in willingness to pay (WTP) experiments. Ninety participants were first randomly assigned to receive either anodal, cathodal, or sham stimulation of 15 minutes, then they performed a valuation task regarding WTP. The results showed that anchoring effects were negatively related to activities of right DLPFC: the anodal stimulation diminished anchoring effects while the cathodal stimulation increased anchoring effects. These outcomes provide one of the first instances of neural evidence for the role of the right DLPFC in anchoring effects and support psychological explanations of the selective accessibility mechanisms and cognitive sets.

BackgroundIn the context of limited health care budgets in countries where Neglected Tropical Diseases (NTDs) are endemic, scaling up disease control interventions entails the setting of priorities. However, solutions based solely on cost‐effectiveness analyses may lead to biased and insufficiently justified priorities.ObjectivesThe objectives of this paper are to 1) demonstrate how a range of equity concerns can be used to identify feasible priority setting criteria, 2) show how these criteria can be fed into a multi‐criteria decision‐making matrix, and 3) (...) discuss the conditions under which this decision‐making procedure should be carried out in a real‐world decision‐making context.MethodsThis paper draws on elements from theories of decision analysis and ethical theories of fair resource allocation. We explore six typical NTD interventions by employing a modified multi‐criteria decision analysis model with predefined criteria, drawn from a priority setting guide under development by the WHO. To identify relevant evidence for the six chosen interventions, we searched the PubMed and Cochrane databases.DiscussionOur in vitro multi‐criteria decision analysis suggested that case management for visceral leishmaniasis should be given a higher priority than mass campaigns to prevent soil‐transmitted helminthic infections. This seems to contradict current health care priorities and recommendations in the literature. We also consider procedural conditions that should be met in a contextualised decision‐making process and we stress the limitations of this study exercise.ConclusionBy exploring how several criteria relevant to the multi‐facetted characteristics of NTDs can be taken into account simultaneously, we are able to suggest how improved priority settings among NTDs can be realised.

Health promotion messages that evoke fear are often used to decrease unrealistic optimism regarding risks, convince people to control their behaviour, and make risks memorable. The relations among emotions, risk and control judgements, and memory are not well understood, however. In the current study, participants (N = 94) were assigned to fearful, angry, happy, or neutral emotion-elicitation conditions. They then rated the likelihood of experiencing 15 negative and 15 positive matched outcomes and rated their degree of control (...) over each outcome. A surprise memory test followed. Fear decreased unrealistic optimism, but the greater the intensity of fear reported the less control participants believed they had over outcomes. Fear also led to poorer memory for outcomes. Across all participants, the lower their ratings of optimism and control concerning outcomes, the less likely they were to recall them. Implications for the use of emotionally evocative material in health promotion messages are discussed. (shrink)

Objective: This study aimed to compare the effects of two intervention programs, high-intensity interval training and moderate-intensity training, on anxiety, depression, stress, and resilience during the confinement caused by the coronavirus disease 2019 in healthy adults.Methods: A total of 67 adults who participated were randomly assigned to two groups: HIIT and MIT groups. The MIT group had to perform a home-based intervention based on aerobic exercises, whereas the HIIT group had to perform a home-based intervention based on HIIT exercises. (...) The two groups had to complete the same physical exercise volume, 40 min per session during the confinement period. Depression, anxiety, stress, and resilience were assessed before and after the intervention.Results: Results showed that HIIT and MIT significantly reduced the stress, anxiety, and depression as well as increase the resilience. Moreover, the improvements obtained in the HIIT group seem to be greater than those of the MIT group in depression.Conclusions: HIIT and MIT decreased anxiety, stress, and depression as well as increased resilience during the COVID-19 confinement. In addition, the HIIT intervention seemed to be more beneficial to reduce depression than the MIT intervention. (shrink)

Background: In this study, we aimed to investigate the effects of a mindfulness program including Mindfulness-Based Stress Reduction on the mental health of student teachers when offered at their educational institution in a real-life context.Methods: A parallel randomized controlled trial was conducted among self-selected student teachers at a Danish undergraduate program for teacher education in the autumns of 2019 and 2020. Participation was not recommended in case of clinical depression or a diagnosis of psychosis or schizophrenia, abuse of alcohol, (...) drugs, and/or medicine. Randomization was performed by a Statistician who was blinded to the identity of the students. Data was collected using self-reported questionnaires. The primary outcome was a change in perceived stress 3 months from baseline. Secondary outcome measures were symptoms of anxiety and depression, well-being, resilience, mindfulness, and thoughts and feelings during rest. The effects were analyzed according to the intention-to-treat principle using mixed-effect linear regression models. Mediating effects of mindfulness skills on the mental health outcomes were explored using structural equation modeling.Results: The study group included 67 student teachers with 34 allocated to the intervention group ; and 33 students allocated to a waiting list control group. At baseline, mean Perceived Stress Scale scores were 18.88 in the intervention group and 17.91 in the waiting list control group. A total of 56 students completed the questionnaire at a 3-month follow-up. Statistically significant effects of the intervention were found on perceived stress, symptoms of anxiety and depression, well-being, and on three of seven resting-state dimensions. No effects were found on resilience or mindfulness. Statistically significant mediated effects via resting-state dimensions were found.Conclusion The findings suggested that offering a mindfulness program at an undergraduate program for teacher education could significantly improve the mental health among self-selected students within 3 months. Results of mediation analysis supported the hypothesis that some of the effects might be explained by reduced distracting thoughts.Clinical Trial Registration: [www.ClinicalTrials.gov], identifier [NCT04558099].

Galvanic vestibular stimulation is a non-invasive method of electrically stimulating the vestibular system. We investigated whether the application of GVS can alter the learning of new functional mobility and manual control tasks and whether learning can be retained following GVS application. In a between-subjects experiment design, 36 healthy subjects performed repeated trials, capturing the learning of either a functional mobility task, navigating an obstacle course on a compliant surface with degraded visual cues or a manual control task, using (...) a joystick to null self-roll tilt against a pseudo-random disturbance while seated in the dark. In the “learning” phase of trials, bilateral, bipolar GVS was applied continuously. The GVS waveform also differed between subjects in each task group: white noisy galvanic vestibular stimulation at 0.3 mA high-level random GVS at 0.7 mA, or with the absence of stimulation. Following the “learning” trials, all subjects were blindly transitioned to sham GVS, upon which they immediately completed another series of trials to assess any aftereffects. In the functional mobility task, we found nGVS significantly improved task learning. Further, improvements in learning the functional mobility task with nGVS were retained, even once the GVS application was stopped. The benefits in learning with nGVS were not observed in the manual control task. High level GVS tended to inhibit learning in both tasks, but not significantly so. Even once the high-level stimulation was stopped, the impaired performance remained. Improvements in learning with nGVS may be due to increased information throughput resulting from stochastic resonance. The benefit of nGVS for functional mobility, but not manual control nulling, may be due to the multisensory, strategic, motor coordination, or spatial awareness aspects of the former task. Learning improvements with nGVS have the potential to benefit individuals who perform functional mobility tasks, such as astronauts, firefighters, high performance athletes, and soldiers. (shrink)
