Rain-harvesting behavior in free-ranging prairie rattlesnakes (Crotalus viridis)

Abstract Organisms inhabiting arid environments face challenges to obtain dietary water. To prevent desiccation, some organisms possess unique adaptations to harvest water from infrequent and unpredictable rainfall, including several squamates (snakes and lizards). While most squamates consume precipitation as it pools in the environment, a small number engage in behaviors to enhance water collection by capturing precipitation from their own skin, referred to as rain-harvesting behavior (RHB). Details of this behavior remain unclear, particularly the sequence of behaviors associated with RHB. We developed a method to simulate rainfall to observe RHB in prairie rattlesnakes (Crotalus viridis) in situ and recorded 72 events in 94 snakes, the most robust sampling of RHB to date. Using video analysis, we describe the postures and kinematics of RHB and develop the first illustrated ethogram of this behavior for any vertebrate. Our results demonstrate that RHB contains fixed and variable patterns useful in cross-species comparisons and in exploring proximate causes of the behavior. Additionally, we describe novel features of RHB including suspended head drinking, body levering, and drinking from neighboring snakes. Our results reveal RHB to be an intricate suite of movements and actions, some of which allude to acute sensory abilities of these animals that warrant further study. Furthermore, observations of RHB at dens and rookeries suggest a potential, novel benefit of snake aggregation is the formation of large, communal surfaces for rain harvesting. We suggest that the extremely elongated body plan of snakes may be well-suited for a rapidly deployed, modular rain-harvesting system effective at capitalizing on fleeting rainstorms characteristic of arid ecosystems of the world.

The effects of cognitive training on driving performance.

Driving is a complex task necessitating an intricate interplay of sensory, motor, and cognitive abilities. Extensive research has underscored the role of neurocognitive functions, including attention, memory, executive functions, and visuospatial skills, in driving safety and performance. Despite evidence suggesting cognitive training's potential in enhancing driving abilities, comprehensive cognitive training's impact on driving performance in young adult drivers remains unexplored. Our study aimed to fill this gap by implementing an intensive, 8-week, multidomain computerized cognitive training program and assessing its transfer effects on the driving performance of young adult drivers, using a high-fidelity simulator. The study employed a randomized controlled trial design, with passive control group. The mixed-design analysis of variance (ANOVA) revealed a notable interaction between the time of testing and the respective participant groups concerning driving performance. Post hoc analyses showed that, compared to the control group, participants undergoing cognitive training demonstrated significantly fewer traffic infractions in the post-training evaluation. These findings suggest that cognitive training could be a useful tool for enhancing driving safety and performance in young adult drivers. Further research should aim to address the limitations posed by the absence of an active control group.

Effect of Early Intervention on Developmental Domains and Parent-Child Interaction Among Children With Developmental Delay: A Randomized Controlled Study.

The scope of early intervention (EI) programs, which mostly focus on motor skills, needs to be expanded. To examine the effects of an EI on developmental domains and parent-child interactions. Randomized controlled study. Children ages 24-36 mo with developmental delay (DD; intervention group, n = 30; control group, n = 40). Pediatric occupational therapy unit of Hacettepe University. The intervention group received an intervention that used the Goal Activity and Motor Enrichment (GAME) approach and a home program, whereas the control group received a home program only. Both groups received the same intervention dosage. Developmental domains were assessed using the Bayley Scales of Infant and Toddler Development Third Edition (Bayley III) and the Ages and Stages Questionnaires (ASQ). Sensory processing was assessed with the Infant/Toddler Sensory Profile 2 (ITSP-2), social-emotional development with the ASQ:Social-Emotional (ASQ:SE), and parent-child interaction with the Parenting Interactions with Children: Checklist of Observations Linked to Outcomes (PICCOLO™). A compliance checklist was used to determine compliance with the home program. A significant between-groups difference was found on all Bayley III and PICCOLO subscales and on the Gross Motor, Fine Motor, Problem-Solving, and Social-Emotional domains of the ASQ and ASQ:SE in favor of the intervention group (p < .05). The intervention group showed more typification (normal sensory processing) in sensory quadrants and general processing. Both groups were 100% compliant with the home program. The GAME-based intervention for children with DD, including sensory and cognitive activities, is effective in improving developmental domains and parent-child interactions. Plain-Language Summary: The scope of early intervention programs mostly focuses on motor skills and needs to be expanded to include the essential roles of children's sensory and cognitive abilities. This study provides important insights into early interventions by occupational therapists and the impact on children with developmental delay and parent-child interactions. We found that the Goal Activity and Motor Enrichment (GAME) intervention for children with developmental delay, which includes sensory and cognitive activities, is effective in improving developmental domains and parent-child interactions.

Machine learning-based personalized composite score dissects risk and protective factors for cognitive and motor function in older participants.

With age, sensory, cognitive, and motor abilities decline, and the risk for neurodegenerative disorders increases. These impairments influence the quality of life and increase the need for care, thus putting a high burden on society, the economy, and the healthcare system. Therefore, it is important to identify factors that influence healthy aging, particularly ones that are potentially modifiable through lifestyle choices. However, large-scale studies investigating the influence of multi-modal factors on a global description of healthy aging measured by multiple clinical assessments are sparse. We propose a machine learning model that simultaneously predicts multiple cognitive and motor outcome measurements on a personalized level recorded from one learned composite score. This personalized composite score is derived from a large set of multi-modal components from the TREND cohort, including genetic, biofluid, clinical, demographic, and lifestyle factors. We found that a model based on a single composite score was able to predict cognitive and motor abilities almost as well as a classical flexible regression model specifically trained for each single clinical score. In contrast to the flexible regression model, our composite score model is able to identify factors that globally influence cognitive and motoric abilities as measured by multiple clinical scores. The model identified several risk and protective factors for healthy aging and recovered physical exercise as a major, modifiable, protective factor. We conclude that our low parametric modeling approach successfully recovered known risk and protective factors of healthy aging on a personalized level while providing an interpretable composite score. We suggest validating this modeling approach in other cohorts.

Sensing Sociality: Disruptions of Social Life When Living With Chemosensory Dysfunctions After COVID-19.

Taste and smell are of direct importance in most social interactions. Radical disruptions in these senses can, therefore, substantially disrupt sociality. This paper focuses on the experiences of a particular type of disruption: persistent chemosensory dysfunctions after COVID-19. We conducted semi-structured interviews with 30 patients undergoing treatment for chemosensory dysfunctions and analyzed the ways in which their experiences have influenced social relations and activities, particularly regarding food and eating. The findings reveal that these dysfunctions have made the participants markedly aware that food and eating are pivotal to full participation in social life. As is smell, both surrounding smells and the perception of one's own smell, with dysfunctions leading to several social consequences. Such problems are handled through both avoidance behavior and adaptations. While adaptations facilitate interactions, they come at the cost of feeling a burden to others or not fully appreciating an event (e.g., a shared meal). Social support is of great importance, ranging from minor practical assistance, such as a friend checking if the milk is sour, to the profound emotional relief felt from empathic treatment and recognition that the problems are real. Here, healthcare professionals can play a vital role, even in the (perceived) absence of clinical effectiveness of the treatment. The experiences expressed are partially in line with other manifestations of Long COVID and with chemosensory dysfunctions due to other illnesses, but only partially, since this is a patient group with needs and experiences that are unique, in that sociality is so strongly affected solely by disruptions in sensory abilities.

Empowering patients: leveraging the untapped potential of smartphone recordings in dermatology consultations.

During consultations, patients can be overwhelmed with new diagnoses, complex treatment plans, particularly when bad news is broken (such as a new skin cancer diagnosis). Patients may be unable to recall nuanced medical information, particularly if elderly, attending on their own, with lower literacy, with impaired sensory abilities and where English may not be their native language. Given the ubiquity of smartphones, recording conversations during consultations—with the doctor’s consent—has become an accessible tool for patients. Allowing patients to record their consultations can empower them, enhance recall, and reduce decisional regret, particularly in emotionally charged settings such as skin cancer clinics where cognitive processing may be impaired.

Sensory Dysfunction, Microbial Infections, and Host Responses in Alzheimer's Disease.

Sensory functions of organs of the head and neck allow humans to interact with the environment and establish social bonds. With aging, smell, taste, vision, and hearing decline. Evidence suggests that accelerated impairment in sensory abilities can reflect a shift from healthy to pathological aging, including the development of Alzheimer's disease (AD) and other neurological disorders. While the drivers of early sensory alteration in AD are not elucidated, insults such as trauma and infections can affect sensory function. Herein, we review the involvement of the major head and neck sensory systems in AD, with emphasis on microbes exploiting sensory pathways to enter the brain (the "gateway" hypothesis) and the potential feedback loop by which sensory function may be impacted by central nervous system infection. We emphasize detection of sensory changes as first-line surveillance in senior adults to identify and remove potential insults, like microbial infections, that could precipitate brain pathology.

Factors affecting the desire to work among elderly people in Thailand

Globally, the number of elderly people is increasing. It is important for elderly people to be financially active to enhance their values and health. Therefore, this study aimed to explore the factors affecting the desire to work among elderly people in Thailand. The present study was a cross-sectional analytical study conducted using the 2017 Elderly Population Survey database of the National Statistical Office, which includes 32,035 individuals. The statistical analysis was performed by a generalized linear mixed model (GLMM). This study revealed that 31.05% of the elderly participants desired to work (95% CI: 30.54-31.55). Statistically significant factors influencing this desire included demographic characteristics such as gender (female, AOR=1.76), age groups (middle elderly stage, AOR=3.13; late elderly stage, AOR=8.88), and literacy (ability to read and write, AOR=1.21). Marital status also played a role, with married (AOR=1.39) and single (AOR=1.37) individuals showing a higher desire to work. Health-related factors were equally important. Those with better physical health had a much higher likelihood of wanting to work compared to those with very poor health (AOR=5.81). Furthermore, engaging in exercise (AOR=1.30), participating in social groups (AOR=2.50), and community activities (AOR=1.11) were positively associated with the desire to work. Sensory abilities, such as clear vision (AOR=1.14) and hearing (AOR=1.42), as well as residing in rural areas (AOR=1.23), also influenced this desire. Approximately one-third of the elderly people were willing to work. Factors that were associated with the desire to work included gender, age, reading and writing ability, marital status, physical health, engaging in exercise, ability to participate in social groups, participation in community activities, vision and hearing ability and location of residence. Therefore, a multidisciplinary approach that considers these factors should be undertaken to promote suitable work for elderly people to enhance their values and health.

A study on comparing sensory processing abilities between general children and children with disabilities using the child sensory profile: The need for standardization

A study on comparing sensory processing abilities between general children and children with disabilities using the child sensory profile: The need for standardization

Decoding acceptance and reappraisal strategies from resting state macro networks

Acceptance and reappraisal are considered adaptive emotion regulation strategies. While previous studies have explored the neural underpinnings of these strategies using task-based fMRI and sMRI, a gap exists in the literature concerning resting-state functional brain networks’ contributions to these abilities, especially regarding acceptance. Another intriguing question is whether these strategies rely on similar or different neural mechanisms. Building on the well-known improved emotion regulation and increased cognitive flexibility of individuals who rely on acceptance, we expected to find decreased activity inside the affective network and increased activity inside the executive and sensorimotor networks to be predictive of acceptance. We also expect that these networks may be associated at least in part with reappraisal, indicating a common mechanism behind different strategies. To test these hypotheses, we conducted a functional connectivity analysis of resting-state data from 134 individuals (95 females; mean age: 30.09 ± 12.87 years, mean education: 12.62 ± 1.41 years). To assess acceptance and reappraisal abilities, we used the Cognitive Emotion Regulation Questionnaire (CERQ) and a group-ICA unsupervised machine learning approach to identify resting-state networks. Subsequently, we conducted backward regression to predict acceptance and reappraisal abilities. As expected, results indicated that acceptance was predicted by decreased affective, and executive, and increased sensorimotor networks, while reappraisal was predicted by an increase in the sensorimotor network only. Notably, these findings suggest both distinct and overlapping brain contributions to acceptance and reappraisal strategies, with the sensorimotor network potentially serving as a core common mechanism. These results not only align with previous findings but also expand upon them, illustrating the complex interplay of cognitive, affective, and sensory abilities in emotion regulation.

Validity of the Systemizer Profile Questionnaire: A New Tool to Identify Cognitive, Mentalizing, Sensory, Social, and Systemizing Abilities in Adults with Autism-Spectrum-Disorders With and Without Comorbid ADHD.

Systemizer Profile Questionnaire (SPQ), which has not been used before, investigates difficulties in mentalisation, sensory- and/or social sensitivity and social cognition (MSSSC) in subjects with Autism-Spectrum-Disorders (ASD) with and without Attention-Deficit-Hyperactivity-Disorder (ADHD). The aim of this study was to evaluate the reliability and validity of the SPQ domains, and to assess the predictive validity of the SPQ against the Ritvo Autism Asperger Diagnostic Scale (RAADS). Three-hundred-fifty-four study subjects with ICD-10 verified ASD confirmed by RAADS and 354 controls matched on age group and gender were recruited and evaluated systematically with SPQ, standardized questions about demographic and clinical data. Hypothesized SPQ subscales formed from 85 items were evaluated using confirmatory factor analysis (CFA). Resulting revised sub-scales were confirmed using item response theory (IRT) and the predictive validity of the SPQ scores was evaluated using RAADS scores above 64 as the standard. Twenty-two of the original 85 items were removed, resulting in an instrument with 63 items across nine psychometrically valid domains. These domains had high sensitivity (range: 0.64 to 0.84), and high specificity (range: 0.73 to 0.90). Positive predictive values (range: 0.76 to 0.89) and negative predictive values (range: 0.69 to 0.90) were also high. For the total SPQ score the sensitivity was 0.95, the specificity was 0.87, the positive predictive value was 0.88 and the negative predictive value was 0.95. SPQ domains are valid descriptions/profiles of MSSSC given that ASD is confirmed by RAADS, though irrelevant if not, as SPQ is not a diagnostic instrument.

A conceptual framework on the role of magnetic cues in songbird migration ecology.

Migrating animals perform astonishing seasonal movements by orienting and navigating over thousands of kilometres with great precision. Many migratory species use cues from the sun, stars, landmarks, olfaction and the Earth's magnetic field for this task. Among vertebrates, songbirds are the most studied taxon in magnetic-cue-related research. Despite multiple studies, we still lack a clear understanding of when, where and how magnetic cues affect the decision-making process of birds and hence, their realised migratory behaviour in the wild. This understanding is especially important to interpret the results of laboratory experiments in an ecologically appropriate way. In this review, we summarise the current findings about the role of magnetic cues for migratory decisions in songbirds. First, we review the methodological principles for orientation and navigation research, specifically by comparing experiments on caged birds with experiments on free-flying birds. While cage experiments can show the sensory abilities of birds, studies with free-flying birds can characterise the ecological roles of magnetic cues. Second, we review the migratory stages, from stopover to endurance flight, in which songbirds use magnetic cues for their migratory decisions and incorporate this into a novel conceptual framework. While we lack studies examining whether and when magnetic cues affect orientation or navigation decisions during flight, the role of magnetic cues during stopover is relatively well studied, but mostly in the laboratory. Notably, many such studies have produced contradictory results so that understanding the biological importance of magnetic cues for decisions in free-flying songbirds is not straightforward. One potential explanation is that reproducibility of magnetic-cue experiments is low, probably because variability in the behavioural responses of birds among experiments is high. We are convinced that parts of this variability can be explained by species-specific and context-dependent reactions of birds to the study conditions and by the bird's high flexibility in whether they include magnetic cues in a decision or not. Ultimately, this review should help researchers in the challenging field of magnetoreception to design experiments meticulously and interpret results of such studies carefully by considering the migration ecology of their focal species.

Blind individuals' enhanced ability to sense their own heartbeat is related to the thickness of their occipital cortex.

Blindness is associated with heightened sensory abilities, such as improved hearing and tactile acuity. Moreover, recent evidence suggests that blind individuals are better than sighted individuals at perceiving their own heartbeat, suggesting enhanced interoceptive accuracy. Structural changes in the occipital cortex have been hypothesized as the basis of these behavioral enhancements. Indeed, several studies have shown that congenitally blind individuals have increased cortical thickness within occipital areas compared to sighted individuals, but how these structural differences relate to behavioral enhancements is unclear. This study investigated the relationship between cardiac interoceptive accuracy and cortical thickness in 23 congenitally blind individuals and 23 matched sighted controls. Our results show a significant positive correlation between performance in a heartbeat counting task and cortical thickness only in the blind group, indicating a connection between structural changes in occipital areas and blind individuals' enhanced ability to perceive heartbeats.

Through an animal's eye: the implications of diverse sensory systems in scientific experimentation.

'Accounting for the sensory abilities of animals is critical in experimental design.' No researcher would disagree with this statement, yet it is often the case that we inadvertently fall for anthropocentric biases and use ourselves as the reference point. This paper discusses the risks of adopting an anthropocentric view when working with non-human animals, and the unintended consequences this has on our experimental designs and results. To this aim, we provide general examples of anthropocentric bias from different fields of animal research, with a particular focus on animal cognition and behaviour, and lay out the potential consequences of adopting a human-based perspective. Knowledge of the sensory abilities, both in terms of similarities to humans and peculiarities of the investigated species, is crucial to ensure solid conclusions. A more careful consideration of the diverse sensory systems of animals would improve many scientific fields and enhance animal welfare in the laboratory.

노인 치매인지교구 및 교수활동안 개발연구

Objectives Due to the super-aging population, the number of elderly people and the number of elderly people with dementia are increasing rapidly, emerging as an important problem in our society. Therefore, there is a need to develop teaching aids necessary for preventing and delaying dementia. Therefore, the purpose of this study is to study teaching activities that can develop and utilize dementia cognitive teaching aids. Methods To achieve this, first, we selected the type of cognitive aids. We identified the types of aids suitable for use in nursing homes or day care centers and selected the appropriate ones. Second, we determined the purpose of the aids. We analyzed the processes of dementia in the elderly and investigated the content of classes in institutions such as nursing homes or day care centers. Third, through literature review, we examined domestically produced cognitive aids, repackaged cognitive aids, and practical cognitive aids. Fourth, we designed the aids in five different areas. Fifth, we conducted a validation and modification process with an expert group, followed by testing the usability of the aids and further modifications. Results Through preliminary research and literature review, we established the development process. As a result, we derived the domains for cognitive aids for elderly dementia patients and outlined teaching activities accordingly. Conclusions First, teaching aids were developed in five areas: language ability, numerical and spatial ability, sensory ability, memory thinking ability, and social relations ability. Second, teaching activity plans for five teaching aids were developed. This was used as a teaching aid for cognitive education for the elderly with dementia in the field, and access to the use of occupational therapists, social workers, and nursing care workers was minimized through the activity plan.

The effect of the Montessori program using physical activity games in enhancing the sensory-motor perception abilities of kindergarten children aged 5 to 6 years

The research aims to propose an educational approach inspired by Montessori's method using motor games to develop sensory motor skills in children aged (5-6) years, and to identify the impact of using Montessori's method with motor games in developing some cognitive sensory motor skills for children. The experimental method was used with the matched group design. The sample represented children from the Braum Al-Amal Nursery in Basra, who were selected to take the Haywood test to measure cognitive sensory motor abilities. It was concluded that Montessori's method using motor games contributed to the development of sensory motor skills and helped in enhancing overall and partial visual perception for children. The child learned about parts of the body, distinguished between body sides, and helped in enhancing balance and spatial awareness. The method also aided in teaching the child how to determine location. It was recommended to benefit from the Montessori method in developing motor and cognitive abilities, and to introduce specific courses for preschool teachers in teaching the Montessori method. Key words: Montessori method, motor games, sensory motor perception, preschool education, teaching methods

Assessment and Rehabilitation Intervention of Feeding and Swallowing Skills in Children with Down Syndrome Using the Global Intensive Feeding Therapy (GIFT).

Children with Down syndrome (DS) experience more difficulties with oral motor skills, including chewing, drinking, and swallowing. The present study attempts to measure the preliminary effectiveness of Global Intensive Feeding Therapy (GIFT) in DS. GIFT is a new rehabilitation program addressing the specific difficulties and needs of each child, focusing on sensory and motor oral abilities. It follows an intensive schedule comprising 15 sessions over 5 consecutive days, with 3 sessions per day. The principles of GIFT are applied with specific objectives for DS. GIFT was preliminarily implemented among 20 children diagnosed with DS. To measure the efficacy of GIFT, the Karaduman Chewing Performance Scale (KCPS), the International Dysphagia Diet Standardization Initiative (IDDSI), and the Pediatric Screening-Priority Evaluation Dysphagia (PS-PED) were used. Data were analyzed using the Wilcoxon signed-rank test before (T0) and after intervention (T1) and at one-month follow-up (T2). The effect size was also measured for specific outcomes, using Kendall's W. Our findings revealed that children with DS showed no risk of dysphagia according to the PS-PED (mean score 2.80). Furthermore, statistically significant improvements in chewing performance were observed, as measured by the KCPS (p < 0.01), as well as in texture acceptance and modification, as measured by the IDDSI post-intervention (p < 0.01). For both the KCPS and IDDSI, a large effect size was found (Kendall's W value > 0.8). Parents/caregivers continued using GIFT at home, and this allowed for a positive outcome at the one-month follow-up. GIFT proved to be effective in the rehabilitation of feeding and swallowing disorders in children with DS, as well as for food acceptance.

Mechanoreception of pneumatic soft robotic finger without tactile sensor based on dual-position feature

Purpose Mechanoreception is crucial for robotic planning and control applications, and for robotic fingers, mechanoreception is generally obtained through tactile sensors. As a new type of robotic finger, the soft finger also requires mechanoreception, like contact force and object stiffness. Unlike rigid fingers, soft fingers have elastic structures, meaning there is a connection between force and deformation of the soft fingers. It allows soft fingers to achieve mechanoreception without using tactile sensors. This study aims to provide a mechanoreception sensing scheme of the soft finger without any tactile sensors. Design/methodology/approach This research uses bending sensors to measure the actual bending state under force and calculates the virtual bending state under assumed no-load conditions using pressure sensors and statics model. The difference between the virtual and actual finger states is the finger deformation under load, and its product with the finger stiffness can be used to calculate the contact force. There are distinctions between the virtual and actual finger state change rates in the pressing process. The difference caused by the stiffness of different objects is different, which can be used to identify the object stiffness. Findings Contact force perception can achieve a detection accuracy of 0.117 N root mean square error within the range of 0–6 N contact force. The contact object stiffness perception has a detection average deviation of about 15%, and the detection standard deviation is 10% for low-stiffness objects and 20% for high-stiffness objects. It performs better at detecting the stiffness of low-stiffness objects, which is consistent with the sensory ability of human fingers. Originality/value This paper proposes a universal mechanoreception method for soft fingers that only uses indispensable bending and pressure sensors without tactile sensors. It helps to reduce the hardware complexity of soft robots. Meanwhile, the soft finger no longer needs to deploy the tactile sensor at the fingertip, which can benefit the optimization design of the fingertip structure without considering the complex sensor installation. On the other hand, this approach is no longer confined to adding components needed. It can fully use the soft robot body’s physical elasticity to convert sensor signals. Essentially, It treats the soft actuators as soft sensors.

Interventions to Improve Sensory Tactile, Auditory, and Visual Down Syndrome Children by Families

Various interventions aimed at addressing sensory challenges are available for Down Syndrome children, but interventions made based on the results of sensory intervention are exciting challenges to research. This study aims to determine the improvement of sensory abilities through stimuli designed based on the results of sensory. This study used a pre-post quantitative method that measured the sensory skills of Down syndrome children. The study was conducted on 8 participants of Down Syndrome children for 12 months. Data analyzed using the Wilcoxon rank test obtained an Asymp value. Sig. (2-tailed) or p-value &lt; 0.05 so that the conclusion is rejected H0 or sufficient evidence that the pretest and post-test sensory development values are different and Asymp values are obtained. The application of examination-based sensory interventions reportedly provided significant improvements in sensory skills in 8 Down Syndrome children after receiving based interventions by following procedures and validated interventions in the form of guidance for parents for 12 months of routine home interventions.
