    好奇心是推动学习和探索的人类基本特质。然而,关于好奇心的研究在医学领域很少受到关注,尽管它有增强知识获取的潜力,工作表现,和社会心理健康。这项研究旨在通过调查医生对他们的好奇心及其在专业实践和医学培训中的作用的个人经历的看法来解决这一差距的一部分。
    这项定性研究是由海德堡大学医学院的12名医生进行的。通过电子邮件随机联系参与者并邀请他们参与研究。数据是通过2019年9月至2020年2月的半结构化访谈收集的。作者采用了Mayring\的方法,这表示一种定性的内容分析方法,其特征是分析文本数据的系统和规则指导方法,旨在提取有意义的见解和模式或主题。确定的主题与总体类别相关联,以从数据中得出结论。
    受访者强调了关于好奇心重要性的三个主要领域[1]:作为(终身)教育的驱动力[2],在建立善解人意的医患关系中,[3]作为优秀研究者的核心素质。他们主要把好奇心和积极的情绪联系起来,虽然好奇心的不表达与不满有关,无聊,和疲惫。诸如繁重的工作量等因素,时间限制,压力,缺乏自主性抑制了他们的好奇心,虽然活动多种多样,与同事进行专业交流,和暴露于新的挑战促进它。内科医生对倦怠和好奇心之间联系的看法并不一致。有趣的是,一些人认为好奇心是对倦怠的保护,而其他人则认为过度的好奇心是沮丧和倦怠的潜在根源。
    这项研究是首次尝试探索医生对医学好奇心的看法。研究结果强调了好奇心在塑造医学专业精神和改善患者护理方面的潜在重要性。然而,医生面临的挑战性工作条件阻碍了它的追求,表明需要加强支持和种植。
    医生认为好奇心是增加他们与医学知识接触的一个重要因素。改善病人护理,培养善解人意的医患关系。时间限制和压力等外部因素成为医生好奇心的主要障碍,强调解决系统性挑战以支持好奇心的重要性。医生对好奇心之间的关系表达了细微差别的观点,幸福和倦怠,这表明需要进行更深入的调查。
    UNASSIGNED: Curiosity is a fundamental human trait that drives learning and exploration. However, research on curiosity has received little attention in the medical field, despite its potential to enhance knowledge acquisition, work performance, and psychosocial well-being. This study aimed to address part of this gap by investigating physicians\' perspectives on their personal experiences with curiosity and its role in their professional practice and medical training.
    UNASSIGNED: This qualitative study was conducted with 12 physicians from the University of Heidelberg Medical Hospital. Participants were contacted randomly via email and invited to participate in the study. Data were collected through semi-structured interviews between September 2019 and February 2020. The authors employed Mayring\'s approach, which denotes a qualitative content analysis method characterized by its systematic and rule-guided approach to analyzing textual data, aiming to extract meaningful insights and patterns or themes. The identified themes were linked to overall categories to draw conclusions from the data.
    UNASSIGNED: The interviewees highlighted three main areas regarding curiosity\'s importance [1]: as a driving force for (lifelong) education [2], in building empathetic physician-patient relationships, and [3] as a core quality of a good researcher. They primarily linked curiosity with positive emotions, while the non-expression of curiosity was associated with dissatisfaction, boredom, and exhaustion. Factors such as heavy workloads, time constraints, stress, and lack of autonomy inhibit their curiosity, while varied activities, professional exchange with colleagues, and exposure to new challenges foster it. Physicians\' perspectives on the link between burnout and curiosity were not consistent. Interestingly, some viewed curiosity as protective against burnout, while others saw excessive curiosity as a potential source of frustration and burnout.
    UNASSIGNED: This study represents the first attempt to explore physicians\' perspectives on curiosity in medicine. The findings highlight the potential importance of curiosity in shaping medical professionalism and improving patient care. However, its pursuit is hampered by the challenging working conditions faced by doctors, suggesting a need for enhanced support and cultivation.
    Physicians identify curiosity as a significant factor in increasing their engagement with medical knowledge, improving patient care, and fostering empathetic doctor-patient relationships.External factors such as time constraints and stress emerge as predominant barriers to physician curiosity, highlighting the importance of addressing systemic challenges to support curiosity.Physicians express a nuanced view of the relationship between curiosity, well-being and burnout, suggesting the need for deeper investigation.

    背景:自杀是一个严重的公共卫生问题。童年创伤的影响,不安全的成人依恋风格和人格特质被认为是自杀未遂的可能危险因素。这个横截面的目的,病例对照研究是调查儿童创伤的影响,成人依恋风格和人格特质对自杀未遂的影响。
    方法:样本包括一方面企图自杀的精神病患者(n=101)和另一方面没有企图自杀的精神病患者(n=114)。使用的问卷是匈牙利验证版本的成人依恋量表(AAS),童年创伤问卷(CTQ),气质和性格量表(TCI)和人口统计问卷。
    结果:结果表明,寻求新颖性(NS)气质特征[EH=1.043;95%C.I.=(0.950-1.145)]p=0.376;情感虐待[EH=1.034;95%C.I.=(0.966-1.107)]p=0.336;情感忽视[EH=1.022;95%C.I.=1.0.659而安全连接方式[EH=0.908;95%C.I.=(0.842-0.980)]p=0.013似乎是一个显着的保护因素(c2(1)=6.515p=0.011)。此外,在研究童年创伤与成人依恋风格之间的联系时,发现焦虑依恋风格与情感虐待呈正相关(rs(197)=0.293)p<0.001,回避依恋风格与情感忽视呈正相关(rs(197)=0.273)p<0.001。
    结论:我们的研究结果表明,具有回避型依恋风格和童年创伤的个体可能表现出更高的自杀风险。但是,安全的依恋方式可能会降低自杀风险。
    BACKGROUND: Suicide is a severe public health problem. Impacts of childhood traumas, unsecure adult attachment styles and personality traits have been suggested as possible risk factors for suicide attempts. The aim of this cross-sectional, case-controlled study is to investigate the impact of childhood traumas, adult attachment styles and personality traits on suicide attempt.
    METHODS: The sample consisted of psychiatric patients who attempted suicide (n=101) on the one hand and those who did not attempt suicide (n=114) on the other. The questionnaires used were the Hungarian validated versions of Adult Attachment Scale (AAS), Childhood Trauma Questionnaire (CTQ), Temperament and Character Inventory (TCI) and a demographic questionnaire.
    RESULTS: Results indicated that Novelty Seeking (NS) temperament trait [EH=1.043; 95% C.I.=(0.950-1.145)] p=0.376; emotional abuse [EH=1.034; 95% C.I.=(0.966-1.107)] p=0.336; emotional neglect [EH=1.022; 95% C.I.=(0.936-1.116)] p=0.626; and sexual abuse [EH=1.047; 95% C.I.=(0.959-1.142)] p=0.305 were associated with nonsignificant increases in the odds of suicide attempts. Whereas secure attachment style [EH=0.908; 95% C.I.=(0.842-0.980)] p=0.013 appeared to be a significantly protective factor (c2(1)=6.515 p=0.011). Furthermore, when examining the connection between childhood traumas and adult attachment styles it was found that the anxious attachment style had a positive significant correlation with emotional abuse (rs(197)=0.293) p<0.001, avoidant attachment style with emotional neglect (rs(197)= 0.273) p<0.001.
    CONCLUSIONS: Our findings suggest that individuals with avoidant attachment style and childhood traumas are likely to present a higher suicide risk. However secure attachment style likely to present a lower risk for suicide.

    在知识经济时代的今天,基于高质量的证据做出决策至关重要。与科学相关的决策被认为依赖于推理技能的复杂相互作用,认知风格,态度,和信息动机。通过调查个体差异与循证决策相关行为之间的关系,我们的目标是更好地了解成年人如何在日常生活中参与科学信息。首先,我们使用数据驱动的探索性方法,在与认知技能和认知态度相关的大量测量中,确定了4个潜在因素.由此产生的结构表明,关键因素包括好奇心和对科学的积极态度,亲社会,认知技能,对新信息的开放态度。第二,我们调查了这些因素是否可以预测自然主义决策任务中的行为。在任务中,向参与者介绍了与科学有关的真实请愿书,并要求他们阅读与请愿书有关的六篇在线文章,科学质量各不相同,决定如何投票。我们证明了好奇心和积极的科学态度,认知灵活性,亲社会和情感状态,与获取信息和证据可靠性识别有关。我们进一步发现,社会权威是来源可信度的有力线索,甚至高于来源的实际质量和相关性。我们的结果突出表明,个人对信息参与的激励因素,比如好奇心,社会权威等社会因素是成年人如何判断日常科学信息来源可信度的重要驱动因素。
    In today\'s knowledge economy, it is critical to make decisions based on high-quality evidence. Science-related decision-making is thought to rely on a complex interplay of reasoning skills, cognitive styles, attitudes, and motivations toward information. By investigating the relationship between individual differences and behaviors related to evidence-based decision-making, our aim was to better understand how adults engage with scientific information in everyday life. First, we used a data-driven exploratory approach to identify four latent factors in a large set of measures related to cognitive skills and epistemic attitudes. The resulting structure suggests that key factors include curiosity and positive attitudes toward science, prosociality, cognitive skills, and openmindedness to new information. Second, we investigated whether these factors predicted behavior in a naturalistic decision-making task. In the task, participants were introduced to a real science-related petition and were asked to read six online articles related to the petition, which varied in scientific quality, while deciding how to vote. We demonstrate that curiosity and positive science attitudes, cognitive flexibility, prosociality and emotional states, were related to engaging with information and discernment of evidence reliability. We further found that that social authority is a powerful cue for source credibility, even above the actual quality and relevance of the sources. Our results highlight that individual motivating factors toward information engagement, like curiosity, and social factors such as social authority are important drivers of how adults judge the credibility of everyday sources of scientific information.

    对人类及其物体的吸引力增加通常是在反复和积极的人类与野生动物相遇(例如在旅游环境中提供的食物)之后产生的。这种“过度吸引”的原因,这可能是由于人类和食物之间的学习联系,在野生动物中的研究仍然很少。了解人类对动物反应的影响对于防止负面影响(例如侵略)至关重要。我们向两组自由放养的棕色skuas展示了三个新颖的物体(Catharactaantarcticassp。lonnbergi)在遥远的南极,它们的栖息地显示没有或最小的人为干扰。一组(Verte)中的Skuas以前曾与人类实验者一起参加过重复的食物奖励行为和认知任务;另一组(Ratmanoff)中的skuas从未这样做过。物体由(i)一个类似天然食物的物体(塑料鱼)组成,(ii)一个人为食物对象(真正的蛋糕片),和(iii)一个人为的非食物物体(黄色手套)。Verte小组的skuas接近人类实验者,并且在新颖的物体上更快地啄食。因此,人类与食物的联系可能会导致对人类的吸引力增加,并对以前幼稚的棕色斯卡鲁进行了新奇的探索,使这个物种成为研究人类经验对野生动物行为的影响的有用模型。
    Increased attraction to humans and their objects often arises after repeated and positive human-wildlife encounters (e.g. food provided in tourist settings). The causes of this \'over-attraction\', which may result from a learned association between humans and food, are still poorly studied in wild animals. Understanding the influence of humans on animals\' responses is yet crucial to prevent negative effects (e.g. aggression). We presented three novel objects to two groups of free-ranging brown skuas (Catharacta antarctica ssp. lonnbergi) in the remote sub-Antarctic, where their habitats show no or minimal human disturbance. Skuas in one group (Verte) had previously participated in repeated food-rewarded behavioural and cognitive tasks with a human experimenter; skuas in the other group (Ratmanoff) had never done so. Objects consisted of (i) one natural-food-resembling object (plastic fish), (ii) one anthropogenic food object (real cake slice), and (iii) one anthropogenic non-food object (yellow glove). Verte group skuas approached the human experimenter and pecked significantly more and sooner at novel objects. Human-food association may have thus resulted in increased attraction to humans and novelty exploration in previously naive brown skuas, making this species a useful model for investigating the consequences of experience with humans on wildlife behaviour.

    尽管好奇心驱动的探索在学习中起着至关重要的作用,我们对如何提高孩子的好奇心的理解仍然有限。这里,我们测试了是否听到了带有好奇心促进主题的战略好奇心故事(例如,战略性地接近不确定性,灵活适应新信息)与具有传统教学主题的控制故事(例如,遵循规则,向他人学习)会影响儿童在两种文化中的战略探索。来自美国(N=138)和土耳其(N=88)的3至6岁儿童被随机分配通过Zoom收听其中一个故事,在玩游戏之前,他们在五个鱼缸中搜索海洋生物。所有的坦克都有相同数量的隐藏点,但它们包含的生物数量不同。时间有限,孩子们不能回到以前的坦克,推动他们战略性地分配搜索工作。结果表明,在这两个国家,处于战略好奇心状态的孩子们更广泛地探索了虚拟的“水族馆”;他们比处于控制状态的孩子更快地穿过坦克,并且更有可能在时间耗尽之前探索所有五个坦克。儿童在战略好奇心条件下也表现出相对更多的战略搜索,根据在每个坦克中找到生物的可能性来调整他们的搜索。虽然需要进一步的研究来查明我们故事中的哪些元素在搜索行为上产生了差异,以及它们是否通过增强或抑制儿童的战略探索来做到这一点。故事书似乎是塑造儿童在多个国家探索的一种有前途的方法。(PsycInfo数据库记录(c)2024APA,保留所有权利)。
    Despite the vital role of curiosity-driven exploration in learning, our understanding of how to enhance children\'s curiosity remains limited. Here, we tested whether hearing a strategic curiosity story with curiosity-promoting themes (e.g., strategically approaching uncertainty, adapting flexibly to new information) versus a control story with traditional pedagogical themes (e.g., following rules, learning from others) would influence children\'s strategic exploration across two cultures. Three- to 6-year-olds from the United States (N = 138) and Turkey (N = 88) were randomly assigned to hear one of these stories over Zoom, before playing a game in which they searched for sea creatures across five fish tanks. All tanks had the same number of hiding spots but varied in the number of creatures they contained. Time was limited and children could not return to prior tanks, pushing them to allocate search effort strategically. Results indicated that across both countries, children in the strategic curiosity condition explored the virtual \"aquarium\" more broadly; they moved through tanks more rapidly than children in the control condition and were more likely to explore all five tanks before time ran out. Children in the strategic curiosity condition also showed relatively more strategic search, adapting their search based on the likelihood of finding creatures in each tank. While further research is needed to pinpoint which elements of our stories produced differences in search behavior and whether they did so by enhancing or inhibiting children\'s strategic exploration, storybooks appear to be a promising method for shaping children\'s exploration across multiple countries.

    婴儿行为——走路,发声,玩耍,与他人互动,等等-提供一个无与伦比的学习和发展窗口。对婴儿的研究需要对观察什么进行战略选择,where,when,以及如何。我们认为,通过允许婴儿和护理人员做他们选择的任何事情来放松研究限制,无论他们选择哪里,无论他们选择什么材料,都有望揭示对学习所基于的日常数据的深刻理解。我们表明,对婴儿自然行为的观察产生了对视觉探索本质的独特见解,对象播放,姿势和运动,接近护理人员,和沟通。此外,我们表明,通过将行为研究置于生态有效的环境中,研究人员可以购买框架学习的上下文规律。最后,我们强调了研究在研究连续性的每一点上的价值-从巧妙控制的基于实验室的任务到日常环境中的完全自然的观察。行为科学的加速取决于利用跨学科的专业知识,理论立场,和方法论方法。
    Infant behaviors-walking, vocalizing, playing, interacting with others, and so on-offer an unparalleled window into learning and development. The study of infants requires strategic choices about what to observe, where, when, and how. We argue that loosening study constraints-by allowing infants and caregivers to do whatever they choose, wherever they choose, and with whatever materials they choose-promises to reveal a deep understanding of the everyday data on which learning builds. We show that observations of infants\' natural behavior yield unique insights into the nature of visual exploration, object play, posture and locomotion, proximity to caregiver, and communication. Furthermore, we show that by situating the study of behavior in ecologically-valid settings, researchers can gain purchase on the contextual regularities that frame learning. We close by underscoring the value of studies at every point on the research continuum-from cleverly controlled lab-based tasks to fully natural observations in everyday environments. Acceleration in the science of behavior rests on leveraging expertise across disciplines, theoretical positions, and methodological approaches.

    在群体中觅食的个人面临着日益激烈的竞争,但可以从有关觅食机会的社会信息中受益,从而最终提高生存率。人格特质可以与食物寻找策略相关,例如Shyer个人寻找他人的食物发现。个性和觅食策略如何在具有不同群体组成的社会觅食环境中相互作用,受到的关注较少。这里,我们进行了实验来研究探索性人格之间的关系,在野生捕获的红色结中,组大小(1-4只鸟)和觅食成功(即找到食物斑块的速度)。我们发现更快的探险家,当独自觅食时,比较慢的探险家更快地发现食物补丁。在团体中,然而,探索速度较慢的鸟类比快速探险者更快地寻找食物。这表明探索速度较慢的个体从群体觅食中受益。他们似乎对社会线索更敏感,与更快的探险家相比,当它们在一起时,它们比单独觅食时更快地找到食物。我们讨论了具有不同性格和觅食策略的个人如何在社会觅食环境中共存,其成本和收益与策略相关。
    Individuals foraging in groups face increased competition but can benefit from social information on foraging opportunities that can ultimately increase survival. Personality traits can be associated with food-finding strategies, such as shyer individuals scrounging on the food discoveries of others. How personality and foraging strategy interact in a social foraging context with different group compositions received less attention. Here, we conducted experiments to investigate the relationship between exploratory personality, group size (1-4 birds) and foraging success (i.e. speed of finding a food patch) in wild-caught red knots. We found that faster explorers, when foraging alone, discover food patches quicker than slower explorers. In groups, however, slower-exploring birds became quicker at finding food than fast explorers. This shows that slower-exploring individuals benefit from group foraging. They seem to be more perceptive to social cues, and in contrast to faster explorers, they become quicker at finding food when they are in a group than when foraging alone. We discuss how individuals with different personalities and foraging strategies can coexist in a social foraging context with different costs and benefits associated with their strategies.

    了解社会交往行为的复杂动态,比如探索,通信,求爱,交配,以及动物模型中的攻击性,对于揭示这些行为背后的关键神经和荷尔蒙机制至关重要。两个入侵者测试旨在调查居民对测试男性的住所内男性和女性入侵者的行为。在这个模拟自然条件的测试中,研究了社会互动的几个方面:探索,求爱,交配,和攻击性行为。由于交配和攻击涉及重叠的神经回路,测试这两种行为的行为设置最能反映它们的竞争性。我们的发现表明,常驻雄性小鼠表现出与雌性入侵者交流的强烈偏好,这与测试男性的基线睾酮水平相关。在BALB/c男性中也发现了双入侵者测试中相关的女性偏好。行为崩溃表明,肛门生殖器嗅探是一个关键的行为特征,可以将居民男性的行为区分为不同性别的入侵者。此外,男性与女性入侵者的互动伴随着下丘脑腹内侧神经元的激活。我们证明,气味识别是男性居民对女性偏好的基础,作为实验性嗅觉缺失减少了与女性入侵者的交流。我们得出结论,两个入侵者测试设置是研究动物模型中社交交流的神经基础的有用工具,详细分析了实验动物在最自然条件下的社会行为的各个方面。
    Understanding the complex dynamics of social communication behaviors, such as exploration, communication, courtship, mating, and aggression in animal models, is crucial to reveal key neural and hormonal mechanisms underlying these behaviors. The two-intruders test is designed to investigate residents\' behavior toward both male and female intruders within the home cage of the test male. During this test imitating natural conditions, several aspects of social interaction were investigated: Exploration, courtship, mating, and aggressive behavior. As mating and aggression involve overlapping neural circuits, the behavioral setup testing both behaviors is best at reflecting their competitive nature. Our findings demonstrate that resident male mice exhibit strong preference to communicate with a female intruder, which correlates with baseline testosterone levels of test males. Relevant female preference in the two-intruders test was also found in BALB/c males. Behavioral breakdown revealed the anogenital sniffing as a key behavioral feature that discriminates resident male behavior toward intruders of different sex. Furthermore, resident male interaction with female intruder was accompanied by neuronal activation in the ventromedial hypothalamus. We demonstrate that odor recognition underlies preference toward females in male residents, as experimental anosmia reduced communication with a female intruder. We conclude the two-intruders test setup to be a useful tool to study the neurological basis of social communication in animal models, which provides detailed analysis of various aspects of the laboratory animals\' social behavior in the most natural conditions.

    早期生活逆境与发展行为障碍的可能性更高有关,环境操纵是一种可以减少早期生活中逆境暴露的负面影响的策略。这里,我们专注于探索环境富集(EE)作为早期生活逆境中的保护因素的影响。我们假设母性剥夺24小时(MD),在生命的第二周,可能会引起焦虑样行为改变,并且由于5-羟色胺能系统的改变,暴露于EE可能会引起对这些行为的复原力。雄性Wistar大鼠暴露于MD,在产后第11天和第13天,以及到EE,断奶后。成年后,我们做了一系列的恐惧行为测试,焦虑,和运动活动。我们还测量了杏仁核和中缝背核中的5-羟色胺水平。我们的结果显示,MD不会影响恐惧行为或血清素水平,而EE在新环境中降低了运动活性,并增强了捕食者气味测试的探索。EE还减少杏仁核中的5-羟色胺并增加其转换率水平。我们的发现提供了对压力暴露影响发育的关键时间框架的见解,并证实暴露于EE对以后生活中的焦虑样行为具有独立和保护作用。
    Early life adversity has been linked with a higher probability of developing behavioral impairments and environmental manipulation is a strategy that may reduce the negative effects of exposure to adversity in early life. Here, we focused on exploring the influence of environmental enrichment (EE) as a protective factor in the context of early life adversity. We hypothesized that 24 hours of maternal deprivation (MD), in the second week of life, could induce anxiety-like behavior alterations and that exposure to EE could induce resilience to these behaviors due to alterations in the serotonergic system. Male Wistar rats were exposed to MD, on postnatal days 11 and 13, and to EE, after weaning. In adulthood, we performed a series of behavioral tests for fear, anxiety, and locomotor activity. We also measured the levels of serotonin in the amygdala and dorsal raphe nucleus. Our results revealed that MD does not impact fear behavior or the levels of serotonin, while EE decreases locomotor activity in a novel environment and enhances exploration in the predator odor test. EE also decreases serotonin in the amygdala and increases its turnover rate levels. Our findings provide insights into the critical timeframe during which stress exposure impacts the development and confirm that exposure to EE has an independent and protective effect for anxiety-like behaviors later in life.

    啮齿动物使用其晶须系统来区分表面纹理。基于晶须的纹理辨别任务通常用于研究编码触觉感觉的机制。一个这样的任务是纹理新颖对象识别测试(tNORT)。它利用了啮齿动物探索新物体而不是熟悉物体的趋势,并评估了晶须在区分不同物体纹理方面的敏感性。它几乎不需要对动物进行训练,所涉及的设备是一个简单的竞技场,通常在里面放置两个物体。测试的成功取决于啮齿动物花费足够的时间探索这些对象。当在有限的时间范围内重复执行时,动物可能会失去对此类任务的兴趣。然而,当建立晶须系统的灵敏度阈值时,这种重复测试可能是至关重要的。在这里,我们提出了一种适应的啮齿动物tNORT协议,旨在即使重复测试也能保持对物体的持续兴趣。我们从三个形状简单的物体构造了复杂的物体。通过不同粒度的砂纸提供不同的纹理。为了尽量减少嗅觉线索,我们使用相同砂纸的沙质和层状面作为随机分配的熟悉和新颖的纹理。随后,我们对八只大鼠进行了重复的tNORT,以确定砂纸砂砾大小的临界阈值,低于该阈值,大鼠将无法将砂子与层状侧面区分开。测试间隔为七天,在五个tNORTs之后,该协议使我们能够成功识别阈值。我们建议提出的tNORT是研究啮齿动物晶须系统灵敏度阈值的有用工具,并通过比较干预前后的敏感性阈值来测试干预的有效性。
    Rodents use their whisker system to discriminate surface texture. Whisker-based texture discrimination tasks are often used to investigate the mechanisms encoding tactile sensation. One such task is the textured Novel Object Recognition Test (tNORT). It takes advantage of a tendency of rodents to explore novel objects more than familiar ones and assesses the sensitivity of whiskers in discriminating different textures of objects. It requires little training of the animals and the equipment involved is a simple arena with typically two objects placed inside. The success of the test relies on rodents spending sufficient time exploring these objects. Animals may lose interests in such tasks when performed repetitively within a limited time frame. However, such repeated tests may be crucial when establishing a sensitivity threshold of the whisker system. Here we present an adapted rodent tNORT protocol designed to maintain sustained interest in the objects even with repeated testing. We constructed complex objects from three simple-shaped objects. Different textures were provided by sandpapers of varying grit sizes. To minimise olfactory clues, we used the sandy and the laminar side of the same sandpaper as the familiar and novel textures assigned at random. We subsequently conducted repeated tNORTs on eight rats in order to identify a critical threshold of the sandpaper grit size below which rats would be unable to discriminate the sandy from the laminar side. With an inter-test-interval of seven days and after five tNORTs, the protocol enabled us to successfully identify the threshold. We suggest that the proposed tNORT is a useful tool for investigating the sensitivity threshold of the whisker system of rodent, and for testing the effectiveness of an intervention by comparing sensitivity threshold pre- and post-intervention.
