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.

Using the GRADE evidence to decision framework to reach recommendations together with ethnic minority community organizations: the example of COVID-19 vaccine uptake in the United Kingdom.

OBJECTIVES: To make recommendations regarding factors that affect COVID-19 vaccine uptake by ethnic minority individuals in the United Kingdom, together with strategies that could be used to increase uptake. STUDY DESIGN AND SETTING: The results of two rapid systematic reviews-one identifying factors that affect respiratory vaccine uptake in ethnic minority adults and the other identifying experimental evaluations of strategies to increase vaccine uptake in ethnic minority adults-were put into Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Evidence to Decision frameworks to support discussion with a panel of ethnic minority community organizations, community-focused small companies, and academics of the relevance of the review findings to the UK COVID context. Aided by the frameworks, the panel made recommendations for factors that need to be addressed to increase vaccine uptake, and for which strategies might be used to increase uptake. RESULTS: Our two reviews contained 31 relevant research studies published in English between 2016 and 2021, all of which were from the United Kingdom (8/31), the United States (20), and Australia (3). We identified six factors-two linked to trust, three linked to information, and one on accessibility-that affected uptake. Strategies that had been evaluated fell into three categories: using trusted messengers, tailoring the message, and increasing convenience. These were put into GRADE Evidence to Decision frameworks and discussed over a series of meetings with individuals from nine ethnic minority community organizations and two community-focused small companies and academics. Community partners provided insight into why ethnic minority individuals in the United Kingdom had lower vaccine uptake, particularly with regard to the impact of nonhealth-related UK Government policy on individuals' heath decision-making. Recommendations included recognizing that trust will be low among some ethnic groups, thinking more broadly as to who messengers should be in a low-trust environment, ensuring that information is tailored to the information needs of specific ethnic groups and working to increase convenience. Our results are at https://www.collaborationforchange.co.uk. CONCLUSION: GRADE Evidence to Decision frameworks could be used more widely to structure discussions of research evidence between researchers, community organizations, and other nonresearch partners.

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.

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.

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.

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.

Strangeness-driven exploration in multi-agent reinforcement learning.

In this study, a novel exploration method for centralized training and decentralized execution (CTDE)-based multi-agent reinforcement learning (MARL) is introduced. The method uses the concept of strangeness, which is determined by evaluating (1) the level of the unfamiliarity of the observations an agent encounters and (2) the level of the unfamiliarity of the entire state the agents visit. An exploration bonus, which is derived from the concept of strangeness, is combined with the extrinsic reward obtained from the environment to form a mixed reward, which is then used for training CTDE-based MARL algorithms. Additionally, a separate action-value function is also proposed to prevent the high exploration bonus from overwhelming the sensitivity to extrinsic rewards during MARL training. This separate function is used to design the behavioral policy for generating transitions. The proposed method is not much affected by stochastic transitions commonly observed in MARL tasks and improves the stability of CTDE-based MARL algorithms when used with an exploration method. By providing didactic examples and demonstrating the substantial performance improvement of our proposed exploration method in CTDE-based MARL algorithms, we illustrate the advantages of our approach. These evaluations highlight how our method outperforms state-of-the-art MARL baselines on challenging tasks within the StarCraft II micromanagement benchmark, underscoring its effectiveness in improving MARL.

Facilitating Youth's Curiosity in Learning: Needs-based Ecological Examinations.

The decline of curiosity during adolescence has received increasing concerns in education. The present study aimed to identify the key factors in the environment that promote young people's curiosity from a needs-based ecological perspective, focusing on family and school. To enable a better understanding of the developmental effects, this study compared two age groups: 10-year-olds and 15-year-olds. A total of 5482 Finnish students (3034 aged 10 and 2448 aged 15; 48% female and 51% male) from the OECD Survey on Social-emotional Skills participated in the study, and their family and school factors related to basic psychological needs (autonomy, competence, relatedness) were assessed through surveys. Hierarchical Linear Modeling results revealed that: (1) contrary to the expectations, factors that support competence and relatedness facilitated youth curiosity to a greater extent than factors that support autonomy; (2) positive relationships with teachers were more beneficial for curiosity among older youth than younger youth; whereas, a sense of belonging at school was the most important factor for younger youth's curiosity. These findings have significant implications for promoting curiosity in general as well as during different age periods.

A transdisciplinary view on curiosity beyond linguistic humans: animals, infants, and artificial intelligence.

Curiosity is a core driver for life-long learning, problem-solving and decision-making. In a broad sense, curiosity is defined as the intrinsically motivated acquisition of novel information. Despite a decades-long history of curiosity research and the earliest human theories arising from studies of laboratory rodents, curiosity has mainly been considered in two camps: 'linguistic human' and 'other'. This is despite psychology being heritable, and there are many continuities in cognitive capacities across the animal kingdom. Boundary-pushing cross-disciplinary debates on curiosity are lacking, and the relative exclusion of pre-linguistic infants and non-human animals has led to a scientific impasse which more broadly impedes the development of artificially intelligent systems modelled on curiosity in natural agents. In this review, we synthesize literature across multiple disciplines that have studied curiosity in non-verbal systems. By highlighting how similar findings have been produced across the separate disciplines of animal behaviour, developmental psychology, neuroscience, and computational cognition, we discuss how this can be used to advance our understanding of curiosity. We propose, for the first time, how features of curiosity could be quantified and therefore studied more operationally across systems: across different species, developmental stages, and natural or artificial agents.

Nonneoplastic pathology of the appendix: A review article, based on the recent literature.

OBJECTIVES: The appendix, although considered a vestigial organ, is of considerable clinical importance because acute appendicitis is a common medical problem. There are also other disease processes involving the appendix. The appendix is among the first specimens that the pathologist (and surgeon) cuts one's teeth on. Thus, there may be a tendency to underestimate the clinically and prognostically significant appendiceal pathologies. METHODS: We provide a vade mecum of the pathologic features of a wide range of nonneoplastic appendiceal pathologies, with an emphasis on developing a practical approach to grossing, microscopy, and reporting-all with clinical and therapeutic implications. Much of this is based on literature on MEDLINE with reference to years 2008 to 2023, as well as on personal experiences and interpretations. RESULTS: The appendix can harbor a myriad of nonneoplastic pathologies, including infections, inflammations of varying etiologies (including interval appendectomy), endometriosis, diverticulosis, and so on. Chronic appendicitis, Crohn disease, and clinical audit are recurring themes while COVID-19 is a new entity. CONCLUSIONS: Most importantly, all pathologists should appreciate that the appendix is not as "routine" a specimen as one would want to believe.

Curious about threats: Morbid curiosity and interest in conspiracy theories in US adults.

Conspiracy theories allege secret plots between two or more powerful actors to achieve an outcome, sometimes explaining important events or proposing alternative understandings of reality in opposition to mainstream accounts, and commonly highlight the threat presented by the plot and its conspirators. Research in psychology proposes that belief in conspiracy theories is motivated by a desire to understand threats and is predicted by increased anxiety. Morbid curiosity describes the tendency to seek out information about threatening or dangerous situations and is associated with an interest in threat-related entertainment and increased anxiety. Across three studies, we investigated the relationship between morbid curiosity and conspiracy theories in US-based samples. We found that higher trait morbid curiosity was associated with higher general conspiracist beliefs (Study 1) and the perceived threat of conspiratorial explanations of events (Study 2). Using a behavioural choice paradigm, we found that participants who chose to investigate morbidly curious stimuli were more likely to choose to learn about conspiratorial explanations for events (Study 3). Greater curiosity about the minds of dangerous people was consistently the strongest predictor of conspiratorial ideation and interest. These results suggest that morbid curiosity is an important but hitherto unstudied predictor of conspiratorial interest and belief.

Using curiosity to counter health information avoidance.

OBJECTIVE: Information that is beneficial for health decision-making is often ignored or actively avoided. Countering information avoidance can increase knowledge of disease risk factors and symptoms, aiding early diagnoses and reducing disease transmission. We examine whether curiosity can be a useful tool in increasing demand for, and engagement with, potentially aversive but useful health information. METHODS: Four pre-registered randomized online studies were conducted with 5795 participants recruited from online survey platforms. Curiosity for aversive health information was manipulated by providing a 'curiosity incentive' - identity-related information alongside aversive information - (Study 1), obscuring information (Studies 2 and 3), and eliciting guesses about the information (Studies 2 and 4). Willingness to view four types of aversive health information was elicited: alcohol consumption screening scores (Study 1), colon cancer risk scores (Study 2), cancer risk factors (Study 3), and the sugar content of drinks (Study 4). RESULTS: In Study 1, the curiosity manipulation increased the likelihood that participants viewed information about the riskiness of their drinking. Studies 2 and 3 show that curiosity prompts can counter people's reluctance to learn about and assess their cancer risk. And Study 4 shows that using curiosity prompts to encourage engagement with aversive information (sugar content of drinks) also improves health-related choices (opting for a sugar-free drink alternative). CONCLUSION: Curiosity prompts provide an effective and simple way to increase engagement with aversive health information.

Memory selectivity in older age.

Memory often declines with age, but older adults can off-set memory challenges by selectively remembering important information. When encountering large amounts of information and knowing that memory is limited, older adults may choose to focus on what is most important and forget less relevant details. Prioritizing what to remember becomes essential when memory is limited, and influences what information can be off-loaded. While forgetting can be frustrating and consequential, a lifetime of these experiences may help older adults learn to focus on strategically remembering important information and life events. Curiosity and emotion may also guide what older adults remember, such that selective remembering can be an adaptive way to use memory efficiently in older age.

Individual differences in processing speed and curiosity explain infant habituation and dishabituation performance.

Habituation and dishabituation are the most prevalent measures of infant cognitive functioning, and they have reliably been shown to predict later cognitive outcomes. Yet, the exact mechanisms underlying infant habituation and dishabituation are still unclear. To investigate them, we tested 106 8-month-old infants on a classic habituation task and a novel visual learning task. We used a hierarchical Bayesian model to identify individual differences in sustained attention, learning performance, processing speed and curiosity from the visual learning task. These factors were then related to habituation and dishabituation. We found that habituation time was related to individual differences in processing speed, while dishabituation was related to curiosity, but only for infants who did not habituate. These results offer novel insights in the mechanisms underlying habituation and serve as proof of concept for hierarchical models as an effective tool to measure individual differences in infant cognitive functioning. RESEARCH HIGHLIGHTS: We used a hierarchical Bayesian model to measure individual differences in infants' processing speed, learning performance, sustained attention, and curiosity. Faster processing speed was related to shorter habituation time. High curiosity was related to stronger dishabituation responses, but only for infants who did not habituate.

Order and change in art: towards an active inference account of aesthetic experience.

How to account for the power that art holds over us? Why do artworks touch us deeply, consoling, transforming or invigorating us in the process? In this paper, we argue that an answer to this question might emerge from a fecund framework in cognitive science known as predictive processing (a.k.a. active inference). We unpack how this approach connects sense-making and aesthetic experiences through the idea of an 'epistemic arc', consisting of three parts (curiosity, epistemic action and aha experiences), which we cast as aspects of active inference. We then show how epistemic arcs are built and sustained by artworks to provide us with those satisfying experiences that we tend to call 'aesthetic'. Next, we defuse two key objections to this approach; namely, that it places undue emphasis on the cognitive component of our aesthetic encounters-at the expense of affective aspects-and on closure and uncertainty minimization (order)-at the expense of openness and lingering uncertainty (change). We show that the approach offers crucial resources to account for the open-ended, free and playful behaviour inherent in aesthetic experiences. The upshot is a promising but deflationary approach, both philosophically informed and psychologically sound, that opens new empirical avenues for understanding our aesthetic encounters. This article is part of the theme issue 'Art, aesthetics and predictive processing: theoretical and empirical perspectives'.

The aesthetic valve: how aesthetic appreciation may switch emotional states from anxiety to curiosity.

Pursuing new knowledge in the entropic environment is pivotal for survival. However, dealing with uncertainty is a costly challenge for the agent surrounded by the stochastic sensory world, giving rise to different epistemic emotions, such as curiosity and anxiety. We recently proposed that aesthetic appreciation may have the role of associating pleasant feedback with the update of predictive representations. According to this idea, aesthetic appreciation and its associated rewarding feeling could drive people to seek new knowledge over anxiety. However, the relationship between aesthetic appreciation, curiosity, and anxiety has been still under-examined in the literature. Here, we explore the relationship between these epistemic emotions in a series of three experiments. In study 1, we examined whether music-induced aesthetic appreciation would influence curiosity in a gambling task. In studies 2a and 2b, we explore the relationship between music-induced aesthetic appreciation and anxiety state. Overall, aesthetic appreciation promoted curiosity-driven behaviour while it was negatively associated with anxiety. These results were consistent with the idea that aesthetic appreciation could act as a 'valve', prompting the individual to perceive curiosity (i.e. to consider novelty as a valuable opportunity to acquire new knowledge) rather than anxiety (i.e. to consider novelty as a risk to be avoided). This article is part of the theme issue 'Art, aesthetics and predictive processing: theoretical and empirical perspectives'.

A model of time-varying music engagement.

The current paper offers a model of time-varying music engagement, defined as changes in curiosity, attention and positive valence, as music unfolds over time. First, we present research (including new data) showing that listeners tend to allocate attention to music in a manner that is guided by both features of the music and listeners' individual differences. Next, we review relevant predictive processing literature before using this body of work to inform our model. In brief, we propose that music engagement, over the course of an extended listening episode, may constitute several cycles of curiosity, attention and positive valence that are interspersed with moments of mind-wandering. Further, we suggest that refocusing on music after an episode of mind-wandering can be due to triggers in the music or, conversely, mental action that occurs when the listener realizes they are mind-wandering. Finally, we argue that factors that modulate both overall levels of music engagement and how it changes over time include music complexity, listener background and the listening context. Our paper highlights how music can be used to provide insights into the temporal dynamics of attention and into how curiosity might emerge in everyday contexts. This article is part of the theme issue 'Art, aesthetics and predictive processing: theoretical and empirical perspectives'.

Originating Research Ideas.

Research aimed at generating new knowledge is the heart of the scholarship of discovery. The author of this paper explores how original research ideas can be generated for formal investigations and artsciencing. Curiosity and creativity are presented as "seeds" for originating ideas, and seven patterns (adjacent possible, liquid networks, the slow hunch, serendipity, error, exaptation, and platforms) are described as synergistic potentiators for geminating original research ideas.

An untapped potential: Curiosity in medical school.

BACKGROUND: There seems to be a common perception among medical educators that curiosity is untapped or even subjugated in medical education. This review aims to summarize research on curiosity across the fields of psychology, neuroscience, and education and report its potential to advance medical education. METHODS: For this narrative review multiple online libraries were searched using variations of the terms curiosity and school/education/learning. Additional studies were reviewed using the reference lists of included studies, and all studies were assessed for quality and relevance. RESULTS: This review of previous research on curiosity shows that curiosity can significantly impact characteristics relevant to medical education, particularly mental health and learning. In addition, the authors outline how curiosity is linked to other epistemic emotions such as anxiety, novelty, surprise, and uncertainty. Finally, an epistemic-emotion-framework (EEF) is proposed to help educators encourage curiosity in medical students. CONCLUSION: By drawing from other research fields, medical educators can learn valuable lessons about the importance of curiosity and how to influence it. This review provides an overview of current research and a framework for how the potential of curiosity can be harnessed to play an important role in students' medical education.

Development and Validation of the Curiosity of Climate Changes Scale.

Introduction: As it is stated by researchers from multiple scientific fields, climate change has real consequences both for the natural environment but also for the human beings, but not everyone is interested in fighting the global warming and its implications. Yet, there are people who are curious about climate change and became invested in the cause of fighting it. Taking this into account, the aim of this study was to create a questionnaire that would enable to measure curiosity about climate change and as such be an useful tool in research regarding this matter. Methods: After examination of existing literature and the evaluation of competent judges, we created a questionnaire which structure and reliability was determined in conducted studies. We also investigated possible correlations between introduced in this paper the Curiosity of Climate Changes Scale (CCCS) and other diagnostic tools: The Curiosity and Exploration Inventory II, The Need for Cognitive Closure Scale, The Elements of Nature Curiosity Scale, The Climate Anxiety Scale, The Environmental Identity Scale and The Generational Time Perspective Scale. Results: The results of the factor analyses verified a one-factor structure. The CCCS showed satisfactory internal consistency (Cronbach's α = 0.95). The validity of the CCCS was indicated by correlations with different scales. The CCCS correlates with general curiosity, curiosity of elements of nature, need for cognitive closure, environmental identity, climate anxiety and generational time perspective. Conclusion: The results indicate that the Curiosity of Climate Changes Scale is a valid and reliable tool. The Curiosity of Climate Changes Scale can be used in future research but also has its practical use - for teachers and environmental educators who thanks to the CCCS can obtain information regarding one's interest in climate change, which can be used in educational programs.
