Exposure to simulated nature promotes positive body image irrespective of the presentation modality: A comparison of images, 2-dimensional film, and 360° immersive film

Previous studies have shown that exposure to simulated natural environments can elevate state body appreciation, but stimulus sets have been limited to the use of images and 2-dimensional (2D) film. To extend this work, we examined the relative impact of images, 2D film, and a 360° immersive film on immediate, state body appreciation. A total of 136 German-speaking adults from Austria (71.3 % women; age range 18–69 years) were randomly assigned to one of three conditions, in which they viewed an image set, a 2D film, or a 360° film depicting the same natural environment. Before and after viewing the stimuli, they completed measures of state body appreciation, affect, and desire for aesthetics. Our results showed that state body appreciation improved in all three conditions, with effect sizes ranging from Cohen’s d = 0.26 (2D film) to 0.52 (360° film). Presentation modality did not significantly shape improvements in state body appreciation; that is, the elevation in state body appreciation was equivalent across all three groups. Participants also experienced improvements in feelings of pleasantness, but again this was independent of the experimental group. These results suggest exposure to simulated nature may improve state body appreciation irrespective of the presentation modality.

Skin conductance response and habituation to emotional facial expressions and words.

Skin conductance response (SCR) serves as a dependable marker of sympathetic activation used to measure emotional arousal. This study investigates the impact of presentation modality (face or word) on the degree of emotional discrimination elicited by SCR. Facial expressions or words associated with six basic emotions-anger, happiness, disgust, fear, sadness, and surprise-were studied among 102 participants. The amplitude of SCR was accurately predicted by subjective arousal ratings of these stimuli, but not by valence ratings. The habituation process to emotional and neutral stimuli across six successive presentations was characterized by an exponential decay function, capturing the rate at which SCR response diminishes in relation to the preceding trial of the same stimulus. Through the subtraction of the response to neutral stimuli from the emotion-evoked SCR, it was demonstrated that the initial presentation of each emotion elicits a substantial response, particularly attributable to the emotional content. Notably, the initial emotional response to faces expressing happiness, disgust, and sadness surpassed that of words conveying the same emotions. The results indicate that different emotional responses can be quantified using a simple electrical instrument.

20 µm resolution multipixel ghost imaging with high-energy x-rays.

Hard x-ray imaging is indispensable across diverse fields owing to its high penetrability. However, the resolution of traditional x-ray imaging modalities, such as computed tomography (CT) systems, is constrained by factors including beam properties, the limitations of optical components, and detection resolution. As a result, the typical resolution in commercial imaging systems that provide full-field imaging is limited to a few hundred microns, and scanning CT systems are too slow for many applications. This study advances high-photon-energy imaging by extending the concept of computational ghost imaging to multipixel ghost imaging with x-rays. We demonstrate a remarkable resolution of approximately 20 µm for an image spanning 0.9 by 1 cm2, comprised of 400,000 pixels and involving only 1000 realizations. Furthermore, we present a high-resolution CT reconstruction using our method, revealing enhanced visibility and resolution. Our achievement is facilitated by an innovative x-ray lithography technique and the computed tiling of images captured by each detector pixel. Importantly, this method maintains reasonable timeframes and can be scaled up for larger images without sacrificing the short measurement time, thereby opening intriguing possibilities for noninvasive high-resolution imaging of small features that are invisible with the present modalities.

Multimodal presentation of E-commerce product reviews and ratings: empirical investigation using multimodality

PurposeThe aim of the research is to evaluate different modality for product reviews presentation and its impact on users’ performance, purchase intention and enjoyment.Design/methodology/approachThe study utilized an experimental approach with 48 opportunistic participants in three groups (16 users per group). Participants were randomly assigned to experimental conditions to ensure unbiased treatment. Data were collected through controlled interventions or manipulations, with pre-defined measures to assess specific outcomes. Statistical techniques such as ANOVA were employed to analyse the data, allowing for comparisons between experimental variables.FindingsThe findings revealed that integrating facial expression avatars and emojis into an e-commerce platform effectively communicates product reviews and ratings. Moreover, the use of animation significantly enhanced user enjoyment. This suggests that visual representations not only convey information effectively but also contribute to a more engaging and enjoyable user experience.Research limitations/implicationsWhile this experiment offers valuable insights into the impact of different e-commerce presentation layouts on user behaviour, further research could delve deeper into specific aspects such as the influence of individual user characteristics and the long-term effects of layout preferences.Originality/valueThis study contributes original insights by demonstrating the efficacy of facial expressive avatars and emojis in conveying product reviews and ratings within e-commerce platforms. Moreover, it adds value by highlighting the positive impact of animation on user enjoyment. By combining these elements, the research offers a novel approach to enhancing user engagement and understanding of customer feedback in online shopping environments. The findings provide valuable guidance for e-commerce platforms seeking innovative ways to communicate product information effectively and enhance the overall user experience, ultimately benefiting both businesses and consumers.

You can't nudge into vaccination: Comparing the effects of nudge types and Covid-19 vaccination attitudes on vaccine willingness.

Nudges can be an effective strategy to promote vaccination. However, it is necessary to better identify the characteristics of nudges that produce the strongest effects and how they interact with individuals' attitudes. Here we sequentially test the effectiveness of three nudge characteristics (framing, nudge type, and presentation modality) and the role of participants' attitudes toward Covid-19 vaccination, social solidarity and authoritarianism in vaccination decisions. In studies 1-4, participants were presented with a nudge manipulating a target characteristic (e.g. positive/negative framing, nudge type) and measuring willingness to vaccinate and related variables compared a control nudge. Study 5 used a single combined nudge reflecting the combination of successful nudges in previous studies. Results over all studies show that nudging has unreliable effects while vaccine attitudes are more reliably linked to all measures of vaccines willingness. These results suggest that attitudes play a more reliable role on effective adoption of vaccinations.

Modifications to consent documentation with adults with communication disorders following brain injury: An exploratory study.

Consent documentation for research studies is often inaccessible to people with neurogenic communication disorders following brain injury and there is limited literature on specific modifications for informed consent. This exploratory study aimed to identify effective strategies and modifications to consent processes for adults with brain injury. Using a fictitious research study, we developed a set of Participant Information Sheets (PISs) varying in complexity, presentation format, and communication modality. Evaluations were conducted with eight participants. Findings indicated diverse participant preferences for PIS modifications, suggesting simplified vocabulary, reduced text, carefully selected images, and an interactive presentation modality as helpful strategies. Building on previous literature, we present refined guidelines for consent modifications for adults with neurogenic communication disorder after brain injury. These guidelines can promote more appropriate inclusion of communicatively impaired populations in research and assist ethics committees and researchers in preparing modified consent documents.

Timing and Modality of Hemorrhoidal Prolapse Impact on Patients' Quality of Life.

Background: The aim of this study was to assess whether the frequency and presentation modality of hemorrhoidal prolapse may have an impact on patients' quality of life, leading to a different categorization of patients. Methods: A consecutive series of patients affected by primary hemorrhoidal disease were administered specific questionnaires to assess the severity of symptoms and their quality of life. The frequency/modality of prolapse was also assessed, and the classification of the patients into five categories was hypothesized. The severity of disease was assessed using a validated patient-reported score, while the health-related quality of life was evaluated with the Short Health Scale for hemorrhoidal disease. Results: A total of 122 patients were enrolled. The evaluation of the prolapse modality led to the following classification: type I, 5 patients (4.1%); type II, 9 (7.4%), type IIIa, 48 (39.3%); type IIIb, 52 (42.6%); and type IV, 8 (6.6%). The mean total hemorrhoidal disease score was 9.8 ± 3.3, while the mean total Short Health Scale score was 18.6 ± 5.2. Both scores progressively increased in the five types of prolapse identified, thus showing a worsening of symptoms and quality of life related to the increase in the frequency and modality of prolapse. The assessment of the quality of life showed that all four domains of the Short Health Scale score and the total score were significantly worse in group IIIb compared to IIIa. Conclusions: The frequency and modality of hemorrhoidal prolapse has an impact on the quality of life and allows the identification of new types of patients.

Effects of multimodal explanations for autonomous driving on driving performance, cognitive load, expertise, confidence, and trust

Advances in autonomous driving provide an opportunity for AI-assisted driving instruction that directly addresses the critical need for human driving improvement. How should an AI instructor convey information to promote learning? In a pre-post experiment (n = 41), we tested the impact of an AI Coach’s explanatory communications modeled after performance driving expert instructions. Participants were divided into four (4) groups to assess two (2) dimensions of the AI coach’s explanations: information type (‘what’ and ‘why’-type explanations) and presentation modality (auditory and visual). We compare how different explanatory techniques impact driving performance, cognitive load, confidence, expertise, and trust via observational learning. Through interview, we delineate participant learning processes. Results show AI coaching can effectively teach performance driving skills to novices. We find the type and modality of information influences performance outcomes. Differences in how successfully participants learned are attributed to how information directs attention, mitigates uncertainty, and influences overload experienced by participants. Results suggest efficient, modality-appropriate explanations should be opted for when designing effective HMI communications that can instruct without overwhelming. Further, results support the need to align communications with human learning and cognitive processes. We provide eight design implications for future autonomous vehicle HMI and AI coach design.

Cultivating Comfort: Examining Participant Satisfaction with Hypnotic Communication Training in Pain Management.

One in four Canadians experiences chronic pain, yet insufficient services and restrictions surrounding prevailing treatments result in inadequate management and significant negative consequences for these individuals. Previous work indicates that hypnotic communication represents a promising complementary treatment; however, training protocols for healthcare professionals are underdeveloped and understudied. To evaluate the level of satisfaction for a training program on hypnotic communication in pain management clinics. Qualitative study. Six health professionals who first completed the hypnotic communication training participated in 30 minutes virtual semi-structured interviews. These testimonials allowed them to elaborate on their user experience and potential areas for improvement. Thematic analysis using qualitative data management software NVIVO was conducted on the interview data. Two themes emerged from the interviews. 1) Satisfaction: Participants expressed satisfaction on various structural aspects of the training, including the provided materials, atmosphere, training structure, presentation modalities, practical workshops, acquired knowledge, trainer quality, and training duration. 2) Areas for Improvement: Five main improvement suggestions were identified (providing more material; more practical workshops, more concrete and adapted; testimonials from former patients; follow-up training meeting; and continuing education). The results improved the training program to help minimized inherent biases related to this technique, cut associated costs, and identify reasons that would explain its underutilization among medical professionals in Quebec. Our work highlights that healthcare professionals in chronic pain management clinics (eg, respiratory therapists, nurses) can incorporate this simple hypnotic communication technique into their usual care and contribute to the well-being of patients. This study aimed to address the lack of training protocols for healthcare professionals, that are underdeveloped and understudied. The main findings on participant' satisfaction and the areas of improvement for the training will help the refinement of the training to better suit healthcare professional's needs in hospitals and chronic pain facilities.

LINGUODIDACTIC FEATURES OF TEACHING ADJECTIVES IN THE COURSE OF UKRAINIAN AS A FOREIGN LANGUAGE

The article delineates the nuances surrounding the meaning, morphological features, syntactic functions, and stylistic attributes of Ukrainian adjectives as a focal point for foreign learners, accompanied by a proposed set of exercises tailored to foster practical proficiency and fluency in their application within speech. It underscores the close association between adjectives and nouns, wherein their interdependency epitomizes the essence of their lexical meaning and grammatical categories. The semantics of adjectives is linked with word-formation structures, encompassing both derivative and non-derivative forms, as well as processes of substantiation. In teaching Ukrainian to non-native speakers, particular emphasis is placed on elucidating the autonomous nature of morphological categories – gender, number, and case – when adjectives assume the role of a noun or predicate. A comprehensive array of morphological variations within adjectives is delineated: 1) forms of word change by gender, number, case; 2) forms of adjectival comparison; 3) short and full (conjugated and unconjugated) forms of adjectives; 4) forms of adjectives by the final consonant of the stem (hard, soft, mixed group). Consideration is given to the formation and utilization of grammatical forms in tandem with the lexical and stylistic nuances inherent to adjectives. Moreover, the article underscores the distinctive approach employed in textbooks targeting Ukrainian as a foreign language when addressing the topic of adjectives. Authors extensively employ tables, instructional rules, generalizations, and grammatical exercises with a communicative emphasis, supplemented by explanatory commentary. It is essential to exercise creativity in leveraging the grammatical content within textbooks, critically evaluating presentation modalities and sequential learning patterns, and devising a comprehensive range of exercises and tasks aimed at cultivating practical aptitude and proficiency in adjective usage within speech. The efficacy of addressing these objectives hinges upon the methodological proficiency of Ukrainian language educators catering to foreign learners. Key words: Ukrainian as a foreign language, adjective, practical grammar, morphological features, syntactic functions, methodological competence.

The Question of HIV Vaccine: Why Is a Solution Not Yet Available?

Ever since its discovery, human immunodeficiency virus type 1 (HIV-1) infection has remained a significant public health concern. The number of HIV-1 seropositive individuals currently stands at 40.1 million, yet definitive treatment for the virus is still unavailable on the market. Vaccination has proven to be a potent tool in combating infectious diseases, as evidenced by its success against other pathogens. However, despite ongoing efforts and research, the unique viral characteristics have prevented the development of an effective anti-HIV-1 vaccine. In this review, we aim to provide an historical overview of the various approaches attempted to create an effective anti-HIV-1 vaccine. Our objective is to explore the reasons why specific methods have failed to induce a protective immune response and to analyze the different modalities of immunogen presentation. This trial is registered with NCT05414786, NCT05471076, NCT04224701, and NCT01937455.

Audio or video? Modality effects on perception, emotions and attitude towards politicians in press conferences

Speeches to the nation offer presidents the potential to influence people. In the COVID-19 pandemic, the leaders’ discourses on the nation have been followed by many citizens in different modalities. However, are there differences if the audience watches or listens to the politician in a press conference? This research examines how the modality of presentation (audio or video) influences the perception of attractiveness, persuasiveness, credibility, emotional response, attitude and voting intention. A sample of 360 participants evaluated these variables after watching two videos and listening to two audio segments of the former president of the United States (Trump), the ex-prime minister of the United Kingdom (Johnson) and the president of the Government of Spain (Sanchez) in press conferences about coronavirus. The results showed that modality is an important variable in the participants’ perceptions, emotions and attitudes. Audio was the format in which politicians were perceived as more attractive, persuasive, credible, energetic and dominant. The attitude towards them and the voting intention were also higher in response to the audio version. However, some emotions, such as neutrality, anger and sadness, were better perceived in the video presentations.

TMFormer: Token Merging Transformer for Brain Tumor Segmentation with Missing Modalities

Numerous techniques excel in brain tumor segmentation using multi-modal magnetic resonance imaging (MRI) sequences, delivering exceptional results. However, the prevalent absence of modalities in clinical scenarios hampers performance. Current approaches frequently resort to zero maps as substitutes for missing modalities, inadvertently introducing feature bias and redundant computations. To address these issues, we present the Token Merging transFormer (TMFormer) for robust brain tumor segmentation with missing modalities. TMFormer tackles these challenges by extracting and merging accessible modalities into more compact token sequences. The architecture comprises two core components: the Uni-modal Token Merging Block (UMB) and the Multi-modal Token Merging Block (MMB). The UMB enhances individual modality representation by adaptively consolidating spatially redundant tokens within and outside tumor-related regions, thereby refining token sequences for augmented representational capacity. Meanwhile, the MMB mitigates multi-modal feature fusion bias, exclusively leveraging tokens from present modalities and merging them into a unified multi-modal representation to accommodate varying modality combinations. Extensive experimental results on the BraTS 2018 and 2020 datasets demonstrate the superiority and efficacy of TMFormer compared to state-of-the-art methods when dealing with missing modalities.

Racialization and sentence intelligibility in older adults with hearing impairment

Previous studies have shown that the perception of a talker’s racial identity affects the intelligibility of that person’s speech to younger, normal-hearing listeners (Babel & Russell, 2015; McGowan, 2015; Tripp, Lyons, & Munson, 2022). These findings show that social perception influences intelligibility. These effects are thought to reflect varied experiences interacting with racially diverse individuals, attitudes and beliefs about different racial groups, or a combination of these factors. The current experiment examines whether the strength of the influence of perceived racial identity on intelligibility is similar across different age groups and levels of hearing acuity. Participants (n = 42, including 16 normal hearing [NH] younger adults, 11 NH older adults, and 15 older adults with hearing loss) were played sentences produced by four talkers who varied in racial identity, in audio-only and audiovisual conditions, in background noise and reported what they heard. Participants also completed a measure of attitudes toward the four talkers. Analyses are ongoing, and examine (1) whether the influence of presentation modality on intelligibility varies across the four talkers, (2) whether these talker differences in audiovisual benefit vary across the three listener groups, and (3) whether attitudes toward the talkers predict intelligibility.

The influence of experience and modality of presentation (online vs. offline) on hypnotizability.

Hypnotizability is conceptualized as a stable personality trait describing the ability to respond to suggestions given under hypnosis. Hypnotizability is a key factor in explaining variance in the effects of hypnotic suggestions on behavior and neural correlates, revealing robust changes mostly in high hypnotizable participants. However, repeated experience and training have been discussed as possible ways to increase willingness, motivation, and ability to follow hypnotic suggestions, although their direct influence on hypnotizability are still unclear. Additionally, it is important whether hypnotizability can be assessed reliably online. We investigated the influence of the degree of experience with hypnosis and the presentation mode (online versus live) on the stability of hypnotizability in two groups of 77 and 102 young, healthy students, respectively. The first group was tested twice with the Harvard Group Scale of Hypnotic Susceptibility (HGSHS) after two weeks. During this period, participants either repeatedly listened to a hypnosis or trained on a progressive muscle relaxation or served as waitlist control group. In the secondgroup, participants performed both an online or offline version of the HGSHS, with varying time intervals (1-6 weeks). Contrary to our expectations, hypnotizability declined from the first to second assessment in the first group. The reductionwas most prominent in initially highly hypnotizable subjects and independent of the experience intervention. We observed a similar reduction of hypnotizability in the second group, independent of presentation modality. The reduction was again driven by initially highly hypnotizable subjects, while the scores of low hypnotizable subjects remained stable. The presentation modality (online vs. offline) did not influence HGSHS scores, but the test-retest reliability was low to moderate (rtt = 0.44). Our results favor the conclusion that generally, hypnotizability is a relatively stable personality trait which shows no major influence of preexperience or modality of assessment. However, particularly highly hypnotizable subjects are likely to experience a decline in hypnotizability in a retest. The role of the concrete assessment tool, psychological factors, and interval length are discussed. Future studies should replicate the experiments in a clinical sample which might have higher intrinsic motivation of increasing responsiveness toward hypnotic interventions or be more sensitive to presentation mode.

Highlighting Opportunities (Versus Outcomes) Increases Support for Economic Redistribution

High levels of economic inequality are associated with numerous negative individual and societal consequences, and people prefer less of it. Opposition to redistributive policies designed to reduce inequality (e.g., taxing the rich to assist the poor), however, remains persistent. In this research, we propose a simple intervention to boost support for such policies. Specifically, we suggest that describing inequality between babies (in rich or poor homes) makes unequal opportunities more salient than describing inequality between adults. Because unequal opportunities are more difficult to rationalize than unequal outcomes, this results in a shift away from individualistic attributions and toward structural attributions for inequality. Critically, structural problems require structural solutions (e.g., redistributive efforts). We test this account across five preregistered studies ( N = 5,800), spanning various presentation modalities (e.g., visual depictions, written descriptions), demographics (e.g., race, gender), inequality-reducing policies (e.g., taxation, food stamps), and a consequential choice underscoring implications for donation behavior.

Vacterl Association with Mayer-Rokitansky-Kuster-Hauser Syndrome, Description of a Case

Vacterl association is a complex dysfunction of congenital malformaciones that implies several structures. Is typically defined by the presence of at least three of the following congenital malformations: vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities. Etiology has only been identified in some patients due to sporadic nature and her high degree of clinical heterogeneity. We report a girl with VACTERL association, which co-occurrence with unusual anomalies of the branchial arch: Mayer-Rokitansky-Küster-Hause syndrome (MRKHS). Vaginal agenesis, is a clinical malformations due to severe dysfunctions in the development of Muller conduits in feminine patient, with absence of vagina and uterus, but with functionals ovaries. Therapeutic management is typically multidisciplinary and centers around surgical correction of specific congenital anomalies in the immediate postnatal period, followed by long-term follow-up for postoperative complications and sequelae of congenital malformations. If optimal surgical correction is achievable, the prognosis may be relatively positive, although some patients will remain affected throughout life. This presentation constitutes a new modality of presentation of polyformative syndromes that need of experience and medical investigation for patients with complex malformation to improve a quality of life.

Ventral and dorsal aspects of the inferior frontal-occipital fasciculus support verbal semantic access and visually-guided behavioural control

The Inferior Frontal Occipital Fasciculus (IFOF) is a major anterior-to-posterior white matter pathway in the ventral human brain that connects parietal, temporal and occipital regions to frontal cortex. It has been implicated in a range of functions, including language, semantics, inhibition and the control of action. The recent research shows that the IFOF can be sub-divided into a ventral and dorsal branch, but the functional relevance of this distinction, as well as any potential hemispheric differences, are poorly understood. Using DTI tractography, we investigated the involvement of dorsal and ventral subdivisions of the IFOF in the left and right hemisphere in a response inhibition task (Go/No-Go), where the decision to respond or to withhold a prepotent response was made on the basis of semantic or non-semantic aspects of visual inputs. The task also varied the presentation modality (whether concepts were presented as written words or images). The results showed that the integrity of both dorsal and ventral IFOF in the left hemisphere were associated with participants’ inhibition performance when the signal to stop was meaningful and presented in the verbal modality. This effect was absent in the right hemisphere. The integrity of dorsal IFOF was also associated with participants’ inhibition efficiency in difficult perceptually guided decisions. This pattern of results indicates that left dorsal IFOF is implicated in the domain-general control of visually-guided behaviour, while the left ventral branch might interface with the semantic system to support the control of action when the inhibitory signal is based on meaning.

Incorporating Community Partner Perspectives on eHealth Technology Data Sharing Practices for the California Early Psychosis Intervention Network: Qualitative Focus Group Study With a User-Centered Design Approach.

Increased use of eHealth technology and user data to drive early identification and intervention algorithms in early psychosis (EP) necessitates the implementation of ethical data use practices to increase user acceptability and trust. First, the study explored EP community partner perspectives on data sharing best practices, including beliefs, attitudes, and preferences for ethical data sharing and how best to present end-user license agreements (EULAs). Second, we present a test case of adopting a user-centered design approach to develop a EULA protocol consistent with community partner perspectives and priorities. We conducted an exploratory, qualitative, and focus group-based study exploring mental health data sharing and privacy preferences among individuals involved in delivering or receiving EP care within the California Early Psychosis Intervention Network. Key themes were identified through a content analysis of focus group transcripts. Additionally, we conducted workshops using a user-centered design approach to develop a EULA that addresses participant priorities. In total, 24 participants took part in the study (14 EP providers, 6 clients, and 4 family members). Participants reported being receptive to data sharing despite being acutely aware of widespread third-party sharing across digital domains, the risk of breaches, and motives hidden in the legal language of EULAs. Consequently, they reported feeling a loss of control and a lack of protection over their data. Participants indicated these concerns could be mitigated through user-level control for data sharing with third parties and an understandable, transparent EULA, including multiple presentation modalities, text at no more than an eighth-grade reading level, and a clear definition of key terms. These findings were successfully integrated into the development of a EULA and data opt-in process that resulted in 88.1% (421/478) of clients who reviewed the video agreeing to share data. Many of the factors considered pertinent to informing data sharing practices in a mental health setting are consistent among clients, family members, and providers delivering or receiving EP care. These community partners' priorities can be successfully incorporated into developing EULA practices that can lead to high voluntary data sharing rates.
