Anxiety and curiosity in hierarchical models of neural emotion processing-A mini review.

Traditionally, two fundamentally different theoretical approaches have been used in emotion research to model (human) emotions: discrete emotion theories and dimensional approaches. More recent neurophysiological models like the hierarchical emotion theory suggest that both should be integrated. The aim of this review is to provide neurocognitive evidence for this perspective with a particular focus on experimental studies manipulating anxiety and/or curiosity. We searched for evidence that the neuronal correlates of discrete and dimensional emotional systems are tightly connected. Our review suggests that the ACC (anterior cingulate cortex) responds to both, anxiety, and curiosity. While amygdala activation has been primarily observed for anxiety, at least the NAcc (nucleus accumbens) responds to both, anxiety and curiosity. When these two areas closely collaborate, as indicated by strong connectivity, this may indicate emotion regulation, particularly when the situation is not predictable.

Systematic Curiosity as an Integrative Tool for Human Flourishing: A Conceptual Review and Framework.

This paper reviews seventy years of theoretical research and proposes systematic curiosity as an integrative tool for human flourishing with a focus on four key aspects: firstly, acknowledge curiosity's multidimensional nature instead of harmonizing its complex taxonomy; secondly, emphasizing intentional curiosity as opposed to impulsive curiosity; thirdly, prioritizing domain-general curiosity for broader applicability across educational, organizational, and therapeutic settings; and lastly, focusing on curiosity as a developable skill rather than an innate trait. By segmenting systematic curiosity into cognitive, emotional, and behavioral components, and relating these to interactions with the self, others, and the world, the framework aims to apply across the spectrum of human experience. Furthermore, the framework encourages an exploration of various evidence-based activities for flourishing so individuals can discover the most suitable strategies for their specific context. Implications for both theory and practice are examined, limitations are discussed, and avenues for future research are suggested.

Wondering and Wandering: In Defense of Free Association and the Fundamental Rule.

"Free association" and the "fundamental rule" are bedrock for psychoanalytic therapy and apply to what both patient and analyst should experience in the process. The article traces Sigmund Freud's revolutionary recognition of the importance of free association that began with his tribute to the works of Ludwig Börne and Friedrich Schiller. The author invokes other proposals akin to free association made by artists and scientists, including John Keats, Charles Dickens, Robert Frost, Thomas S. Kuhn, Arthur Koestler, and Albert Einstein. While emphasizing the importance and the liberatory potential of free association as it relates to effective treatment and discovery, the author contends that there is a "moral press" for both the patient and the analyst to permit free associative thoughts, particularly to question assumptions about how things are supposed to be.

Role of Metacognitive Confidence Judgments in Curiosity: Different Effects of Confidence on Curiosity Across Epistemic and Perceptual Domains.

Previous research suggests that curiosity is sometimes induced by novel information one has no relevant knowledge about, but it is sometimes induced by new information about something that one is familiar with and has prior knowledge about. However, the conditions under which novelty or familiarity triggers curiosity remain unclear. Using metacognitive confidence judgments as a proxy to quantify the amount of knowledge, this study evaluates the relationship between the amount of relevant knowledge and curiosity. We reviewed previous studies on the relationship between subjective curiosity and confidence and reanalyzed existing large-sample data. The findings indicate that the relationship between curiosity and confidence differs depending on the nature of the stimuli: epistemic versus perceptual. Regarding perceptual stimuli, curiosity is stronger when individuals have lower confidence levels. By contrast, for epistemic stimuli, curiosity is stronger when individuals have higher confidence levels. These results suggest that curiosity triggered by perceptual stimuli is based on perceived novelty, whereas that triggered by epistemic stimuli is based on familiarity with prior knowledge.

How Does Active Learning Pedagogy Shape Learner Curiosity? A Multi-Site Mediator Study of Learner Engagement among 45,972 Children.

Curiosity is one of the most fundamental biological drives that stimulates individuals' intense desire to explore, learn, and create. Yet, mechanisms of how curiosity is influenced by instructional pedagogy remain unclear. To shed light on this gap, the present study sets out to investigate the underlying channels linking active learning pedagogy, learner engagement, and learner curiosity, employing a partial least-squares structural equation model leveraging the Social and Emotional Skills Survey dataset across ten sites (N = 45,972). Findings indicate that active learning pedagogy is positively associated with learner engagement (std. ß = 0.016, p = 0.005), but there lacks a significant direct effect on learner curiosity (std. ß = -0.001, p = 0.738). Structural mediation results show that learner engagement is a key mediating channel linking active learning pedagogy and learner curiosity (std. ß = 0.013, p = 0.005).

Organisms have gravity: taking an organism-centered approach in experimental biology.

When you take the time to observe another organism, there is a sort of gravity that can take hold, a mixture of curiosity and connection that expands and strengthens the more you interact with that organism. Yet, in research, a connection with one's study organism can, at times, feel countercultural. Study organisms are sometimes viewed more as tools to conveniently study biological questions. Here, we explicitly highlight the importance of organism-centered research not only in scientific discovery, but also in conservation and in the communication and perception of science.

"Trying to write a story together": general practitioners' perspectives on culturally sensitive care.

BACKGROUND: Culturally sensitive care is integral to effective and equitable healthcare delivery, necessitating an understanding and acknowledgment of patients' cultural needs, preferences, and expectations. This study investigates the perceptions of cultural sensitivity among general practitioners (GPs), focusing on their intentions, willingness and perceived responsibilities in providing care tailored to cultural needs. METHODS: In-depth interviews were conducted with 21 Flemish GPs to explore their perspectives on culturally sensitive care. Data analysis followed a conventional qualitative content analysis approach within a constructivist framework. A coding scheme was developed to identify recurring themes and patterns in the GPs' responses. RESULTS: Findings reveal that culturally sensitive care provision is perceived as a multifaceted process, initiated by an exploration phase where GPs inquire about patients' cultural needs and preferences. Two pivotal factors shaping culturally sensitive care emerged: patients' specific cultural expectations and GPs' perceived responsibilities. These factors guided the process of culturally sensitive care towards three distinct outcomes, ranging from complete adaptation to patients' cultural requirements driven by a high sense of responsibility, through negotiation and compromise, to a paternalistic approach where GPs expect patients to conform to GPs' values and expectations. Three typologies of GPs in providing culturally sensitive care were identified: genuinely culturally sensitive, surface-level culturally sensitive, and those perceiving diversity as a threat. Stereotyping and othering persist in healthcare, underscoring the importance of critical consciousness and cultural reflexivity in providing patient-centered and equitable care. CONCLUSIONS: This study emphasizes the significance of empathy and underscores the necessity for GPs to embrace the exploration and acknowledgement of patients' preferences and cultural needs as integral aspects of their professional role. It highlights the importance of shared decision-making, critical consciousness, cultural desire and empathy. Understanding these nuances is essential for enhancing culturally sensitive care and mitigating healthcare disparities.

Neural mechanisms of information seeking.

We ubiquitously seek information to make better decisions. Particularly in the modern age, when more information is available at our fingertips than ever, the information we choose to collect determines the quality of our decisions. Decision neuroscience has long adopted empirical approaches where the information available to decision-makers is fully controlled by the researchers, leaving neural mechanisms of information seeking less understood. Although information seeking has long been studied in the context of the exploration-exploitation trade-off, recent studies have widened the scope to investigate more overt information seeking in a way distinct from other decision processes. Insights gained from these studies, accumulated over the last few years, raise the possibility that information seeking is driven by the reward system signaling the subjective value of information. In this piece, we review findings from the recent studies, highlighting the conceptual and empirical relationships between distinct literatures, and discuss future research directions necessary to establish a more comprehensive understanding of how individuals seek information as a part of value-based decision-making.

The Protective Role of Curiosity Behaviors in Coping with Existential Vacuum.

An existential vacuum is experienced as a kind of crisis that one can cope with using his/her strengths. The related literature suggests that the important determinants of coping with existential emptiness include positive emotional and personality resources, and among these-Curiosity Behaviors. The purpose of this study is to describe the role of curiosity as an important factor in relation to emotional resources in individuals experiencing an existential vacuum. A survey was conducted using online tools (n = 484). The hypotheses about the direct and indirect relationships between Curiosity Behaviors and existential vacuum were tested using multiple regression analyses and mediations. The study involved a sample of adult participants representing the general population. The participants completed five questionnaires, the first one focusing on Curiosity Behaviors, such as seeking out novel and challenging experiences and engagement in activities that capture one's attention (The Curiosity and Exploration Inventory), and the other tools being the Multidimensional Existential Meaning Scale, the Emotional Regulation Questionnaire, the Flourishing Scale, and the Depression Anxiety Stress Scale. The results indicate that Curiosity Behaviors characteristically negatively predict existential vacuum. In addition, other variables, such as Flourishing, seem to be useful in explaining the relationships between these factors. Flourishing along with Curiosity increases a sense of Meaning in Life. Our results present evidence showing the importance of Curiosity Behaviors in coping with the existential vacuum.

Susceptibility to Electronic Cigarette and Consumption Patterns in Adolescents.

The use of electronic cigarettes (ECs) is a major problem globally. Susceptibility and curiosity are important factors that develop prior to the onset of substance use, such as ECs, and are therefore considered as predictors. Both factors are used to obtain an extended index of susceptibility (ESIe-c), which allows the identification of adolescents who are at risk of starting to use these devices. The aim of this study was to determine the prevalence of EC consumption and to assess the association of possible predictors with susceptibility to use and experimentation with ECs among adolescents. A cross-sectional study was carried out in 377 adolescents (53.0% female). Participants were compared according to their experimentation with ECs. A total of 45.9% had already used electronic cigarettes, and 20.8% were current users. Among those who had not tried electronic cigarettes, 43.3% had a medium-high susceptibility to EC initiation. Consumption among close friends, receiving offers of consumption and alcohol consumption were associated with initiation. There was an inverse association between a medium susceptibility index electronic cigarette score and the consumption of cigarettes and positive affect; on the other hand, the lack of premeditation was associated with a higher susceptibility index score. Intrapersonal factors and social factors seem to influence the ESIe-c and onset of EC use, respectively. The main conclusion in this study is that susceptibility is influenced by intrapersonal factors such as affectivity and impulsivity through the lack of premeditation, and by social factors such as EC consumption by best friends.

Unperceived, the impact of information gap design plateware on food waste.

Curiosity is a powerful motivator of behaviour. Although there have been some studies pertaining to the application of curiosity in the realm of food, research examining the potential to influence consumer food waste behaviour through the induction of curiosity is lacking. This study conducted two onsite dining experiments to explore the role and mechanism of curiosity in reducing food waste in a real dining environment by utilising an information gap design in tableware to induce participants' curiosity. Experiment 1 investigated the differences in food waste between participants using bowls with an information gap design and those using bowls with no information gap (blank bowls). Experiment 2 further controlled for other variables that could potentially influence the outcomes between bowls with and without information gaps; the latter displayed complete text externally. The results of both experiments consistently demonstrated a significant reduction in participants' food waste when utilising utensils with an information gap design. Moreover, we conducted an exploratory analysis combining these two experiments to examine the mediating mechanisms involved. Furthermore, the exploratory analysis suggested the mediating mechanism of curiosity elicited by the information gap design, ultimately leading to a decrease in food waste. This study presents a potential avenue for a simple and innovative approach for mitigating food waste.

Using curiosity to render the invisible, visible.

Virtues commonly associated with physicians and other healthcare professionals include empathy, respect, kindness, compassion, trustworthiness, and many more. Building upon the work of Bortolloti, Murphy-Hollies, and others, I suggest that curiosity as a virtue has an integral role to play in healthcare, namely, in helping to make those who are invisible, visible. Practicing the virtue of curiosity enables one to engage with and explore the experiences of patients and contributes toward building a physician-patient relationship of trust. As the perspectives and experiences of patients can be too often dismissed or lost within medical settings, curiosity can allow physicians to deeply know their patients, and thus provide better care. However, caution must be exercised so as to not to venture into inappropriate curiosity, where questions are asked for improper reasons or to help satisfy the personal interest of physicians. Finally, I sketch out two cases-on chronic pain and on vaccine hesitancy-to illustrate where curiosity can play a valuable role.

The quality of caregiver-child interaction is predicted by (caregivers' perception of) their child's interests.

This current study examines the extent to which children's interests and caregivers' sensitivity to their children's interests are associated with the quality of caregiver-child interaction, and subsequent learning. Eighty-one caregiver-child dyads (24-30-month old children) completed an online shared book-reading task where caregivers and children read two e-books with pictures and descriptions of objects from different categories-one previously determined to be of low and one of high interest to the child (with one novel word-object mapping introduced in each book). We also obtained separate behavioural indices of children's interests and children's later recognition of newly introduced word-object mappings. Our findings highlight that the quality of caregiver-child interaction is predicted by children's interests and caregivers' perception of children's interests, although we find only limited overlap between our behavioural indices of children's interests and caregiver perception of children's interests. Neither of these factors predicted later novel word recognition. Thus, while the dynamics between higher quality of caregiver-child interaction, children's interests and learning remain inconclusive, caregivers and children appear to be more attentive, enthusiastic and engaged in reading about topics that (caregivers believe) interest the child. Furthermore, learning in itself seems to be successful, regardless of factors involved, through the mere task of shared book reading.

Uncertain world: How children's curiosity and intolerance of uncertainty relate to their behaviour and emotion under uncertainty.

Curiosity and intolerance of uncertainty (IU) are both thought to drive information seeking but may have different affective profiles; curiosity is often associated with positive affective responses to uncertainty and improved learning outcomes, whereas IU is associated with negative affective responses and anxiety. Curiosity and IU have not previously been examined together in children but may both play an important role in understanding how children respond to uncertainty. Our research aimed to examine how individual differences in parent-reported curiosity and IU were associated with behavioural and emotional responses to uncertainty. Children aged 8 to 12 (n = 133) completed a game in which they were presented with an array of buttons on the screen that, when clicked, played neutral or aversive sounds. Children pressed buttons (information seeking) and rated their emotions and worry under conditions of high and low uncertainty. Facial expressions were also monitored for affective responses. Analyses revealed that children sought more information under high uncertainty than low uncertainty trials and that more curious children reported feeling happier. Contrary to expectations, IU and curiosity were not related to the number of buttons children pressed, nor to their self-reported emotion or worry. However, exploratory analyses suggest that children who are high in IU may engage in more information seeking that reflects checking or safety-seeking than those who are low in IU. In addition, our findings suggest that there may be age-related change in the effects of IU on worry, with IU more strongly related to worry in uncertain situations for older children than younger children.

Inspection Robot Navigation Based on Improved TD3 Algorithm.

The swift advancements in robotics have rendered navigation an essential task for mobile robots. While map-based navigation methods depend on global environmental maps for decision-making, their efficacy in unfamiliar or dynamic settings falls short. Current deep reinforcement learning navigation strategies can navigate successfully without pre-existing map data, yet they grapple with issues like inefficient training, slow convergence, and infrequent rewards. To tackle these challenges, this study introduces an improved two-delay depth deterministic policy gradient algorithm (LP-TD3) for local planning navigation. Initially, the integration of the long-short-term memory (LSTM) module with the Prioritized Experience Re-play (PER) mechanism into the existing TD3 framework was performed to optimize training and improve the efficiency of experience data utilization. Furthermore, the incorporation of an Intrinsic Curiosity Module (ICM) merges intrinsic with extrinsic rewards to tackle sparse reward problems and enhance exploratory behavior. Experimental evaluations using ROS and Gazebo simulators demonstrate that the proposed method outperforms the original on various performance metrics.

The Role of Stimulus Uncertainty and Curiosity in Attention Control.

Most cognitive psychological studies assume that participants in lab-based tasks maintain a single goal based on task instructions. However, people can be motivated by other factors, such as curiosity. We examined if people attend to seemingly task-irrelevant information out of curiosity by manipulating stimulus uncertainty in a cueing paradigm. Participants were presented with an abrupt-onset cue followed by a letter target (E or H). Next, a mask either at the target location (low uncertainty) or at all four locations (high uncertainty) was shown. We expected high uncertainty to induce a state of curiosity that in turn influences the processing of the cue. Cueing effects were greater in the high-uncertainty condition compared to the low-uncertainty condition. In Experiment 2, we additionally elicited self-report ratings on curiosity. In sum, target-specific uncertainty leads to greater processing of task-irrelevant peripheral cues across two experiments. We tentatively conclude that uncertainty modulates attention control and further research is necessary to examine if this is indeed due to curiosity induced by uncertainty.

Non-alcoholic beverage consumption among US adults who consume alcohol.

BACKGROUND AND AIMS: Non-alcoholic beverages (NABs) that mimic alcohol without inducing intoxication, such as non-alcoholic beers, non-alcoholic wines and spirit-free drinks, are increasing in popularity. It is unknown whether NABs help to mitigate or stimulate alcohol use. The present study aimed to describe NAB consumption practices among US adults consuming alcohol, characterize who is likely to consume NABs and examine whether NAB use influences desire for and perceived consumption of alcohol. DESIGN AND PARTICIPANTS: The survey study used data collected June-July 2023 from an on-line convenience sample. The first survey (n = 1906) assessed frequency of NAB consumption among US adults who consume alcohol. A second more detailed survey on use patterns was conducted with 466 respondents who reported past-year NAB consumption, of whom 153 (32.83%) screened positive on the CAGE questionnaire for alcohol use disorder (AUD). SETTING: This study took place in the United States. MEASUREMENTS: NAB consumption measures included type of NAB consumed, frequency, quantity, first consumption age, consumption reasons, consumption contexts and perceived effect on desire for and consumption of alcohol. Alcohol use measures included frequency, quantity and first consumption age. FINDINGS: Past-year NAB use was endorsed by 28.44% of respondents (61.70% ever used). Non-alcoholic liquor/'mocktails' were the most common NAB type consumed (83.69%). Compared with respondents without AUD, those who screened positive for AUD were significantly more likely to consume NABs in an effort to decrease or abstain from drinking alcohol [adjusted odds ratio (AOR) = 3.54, 95% confidence interval (CI) = 2.24-5.58] and 67.97% endorsed less alcohol consumption (3.23% endorsed more) due to their NAB use. NAB consumption frequency and quantity were significantly positively predicted by alcohol consumption frequency (AOR = 1.46, 95% CI = 1.17-1.83) and quantity (ß = 0.25, 95% CI = 0.15-0.35), respectively. CONCLUSION: Adults who consume alcohol and screen positive for alcohol use disorder report drinking non-alcoholic beverages as a harm reduction strategy.

Curiosity and the dynamics of optimal exploration.

What drives our curiosity remains an elusive and hotly debated issue, with multiple hypotheses proposed but a cohesive account yet to be established. This review discusses traditional and emergent theories that frame curiosity as a desire to know and a drive to learn, respectively. We adopt a model-based approach that maps the temporal dynamics of various factors underlying curiosity-based exploration, such as uncertainty, information gain, and learning progress. In so doing, we identify the limitations of past theories and posit an integrated account that harnesses their strengths in describing curiosity as a tool for optimal environmental exploration. In our unified account, curiosity serves as a 'common currency' for exploration, which must be balanced with other drives such as safety and hunger to achieve efficient action.

Cultivating curiosity: Consumer responses to ethical and product benefits in cultured foods.

Cultured foods have the potential to profoundly transform the food industry. However, most current research focuses on cultured meat, neglecting other cultured products and begging the question of whether different promotional approaches are suited for certain types of cultured food products than others. To bridge this knowledge gap, we carried out two studies to explore how product type (cultured meat vs. cultured fruit) and benefit type (ethical vs. product attributes such as sensory and nutritional advantages) interact in determining consumers' willingness to try the products. Study 1 findings indicate that emphasizing ethical benefits is more effective for promoting cultured meat, whereas highlighting product benefits is more effective for promoting cultured fruit. We found that curiosity, a strong behavioral motivator, mediates the interactive effect of product type and benefit type on willingness to try. This research underscores the need for marketing messages to be tailored to the distinct cultured product types and enriches the literature on curiosity as an important mechanism in the context of cultured food acceptance.

Infants' attention during cross-situational word learning: Environmental variability promotes novelty preference.

Infants as young as 14 months can track cross-situational statistics between sets of words and objects to acquire word-referent mappings. However, in naturalistic word learning situations, words and objects occur with a host of additional information, sometimes noisy, present in the environment. In this study, we tested the effect of this environmental variability on infants' word learning. Fourteen-month-old infants (N = 32) were given a cross-situational word learning task with additional gestural, prosodic, and distributional cues that occurred reliably or variably. In the reliable cue condition, infants were able to process this additional environmental information to learn the words, attending to the target object during test trials. But when the presence of these cues was variable, infants paid greater attention to the gestural cue during training and subsequently switched preference to attend more to novel word-object mappings rather than familiar ones at test. Environmental variation may be key to enhancing infants' exploration of new information.
