The costs of curiosity and creativity: Minimizing the downsides while maximizing the upsides.

The unbridled positivity toward curiosity and creativity may be excessive. Both aid species survival through exploration and advancement. These beneficial effects are well documented. What remains is to understand their optimal levels and contexts for maximal achievement, health, and well-being. Every beneficial element to individuals and groups carries the potential for harm - curiosity and creativity included.

Enhancing gender equality for women using person-centred care and cultural curiosity.

Socially constructed gender norms influence people's access to, and experience of, healthcare. Gender norms can negatively affect the health of women, men and people with other gender identities, such as transgender or non-binary individuals. Person-centred care and shared decision-making, which are widely recognised as essential aspects of healthcare, could be effective approaches for enhancing gender equality in healthcare for women. However, many women appear to receive suboptimal person-centred care. Additionally, there is a lack of representation of diverse gender identities in research, as well as a lack of awareness of diverse gender identities among nurses and other healthcare professionals. To enhance gender equality in healthcare for women, nurses and nursing students should be encouraged to reflect on their unconscious biases and adopt a stance of cultural curiosity, while organisations need to improve preregistration and post-registration training on equality and diversity.

Transgenerational plasticity of exploratory behavior and a hidden cost of mismatched risk environments between parental sexes.

We require a better understanding of the relative contribution of different modes of non-genetic inheritance in behavioral trait development. Thus, we investigate variation in exploratory behavior, which is ecologically relevant and a target of selection. The metabolic hypothesis predicts exploratory behavior to be size-dependent across taxa. This size-dependency is cancelled out under high perceived risk, allowing us to determine the transgenerationally integrated estimated level of risk. Using fathead minnows Pimephales promelas, we manipulated perceived risk in mothers, fathers, caring males and offspring through continuous exposure to either conspecific alarm cues or to a control water treatment. In 1000 four-month old offspring, we determined body sizes and exploratory behavior. Perceived high risk in mothers, followed by personal risk, was most effective in eliminating size-dependent behavior whereas effects of paternal risk on offspring behavioral development were substantially weaker. When maternal risk is high, environmental mismatches between parents prevented offspring from responding appropriately to personal high risk. The environment of the caring male also impacted offspring behavior to a greater extent than that of its genetic parents. Our study highlights the high relative importance of maternal, personal and caring male risk environments and showcases potential costs of an environmental mismatch between parental sexes.

Identidade profissional do psicólogo judiciário: um estudo sobre configurações identitárias / Forensic psychologist´s professional identity: a study about identity configurations / Identidad profesional del psicólogo forense: un estudio sobre configuraciones de identidad

Este estudo objetivou descrever a identidade profissional de psicólogos judiciários, partindo do cenário contemporâneo da Psicologia Jurídica brasileira, contexto que envolve crises e conflitos sobre a forma de responder a atribuições e demandas do campo legal. Pela perspectiva da sociologia das identidades profissionais de Claude Dubar, sustenta-se a hipótese de que a identidade profissional do psicólogo judiciário depende de estratégias de compatibilização entre o pertencimento à categoria e as atribuições legais e institucionais. Participaram 95 psicólogos do quadro ativo do Tribunal de Justiça de São Paulo, que responderam a um formulário online sobre a percepção de si e do campo de atuação. Os dados foram submetidos à análise de conteúdo. Os resultados indicam a saliência da avaliação psicológica e da interdisciplinaridade na identidade profissional, e as rupturas identitárias diante de práticas verificatórias. Tais achados apontam a necessidade de participação da categoria na construção de suas atribuições; e dificuldades para o exercício das funções por limitações à autonomia profissional.(AU)

This study aimed to describe the professional identity of forensic psychologists, considering Brazil's Legal Psychology contemporary scenario which relates to a critical issues on how practitioners respond the demands of the legal system. Based on Claude Dubar's sociology of professional identities, we support the hypothesis that forensic psychologists' professional identity depends on strategies of compatibilization between belonging their reference group and the institutional attributions. There were 95 participants, all from the current staff of the Court of Justice of the state of São Paulo, who answered an online form. The data were subjected to content analysis. The results indicate a professional identity with noted salience on psychological assessment and interdisciplinarity, and the identity crises regarding verification practices. Such findings highlight the importance of practitioners taking part on the construction of their own tasks.(AU)

Este estudio tuvo como objetivo describir la identidad profesional de los psicólogos forenses, considerando el escenario de la Psicología Jurídica brasileña, que se relaciona con una crisis sobre si estos profesionales responden a las demandas del sistema legal. Teniendo en cuenta la sociología de las identidades profesionales de Claude Dubar, sostenemos la hipótesis de que la identidad profesional de los psicólogos forenses depende de estrategias de compatibilización entre la pertenencia a su grupo profesional y a instituciones. Participaron 95 psicólogos, quienes actuaban en el Tribunal de Justicia del Estado de São Paulo, a los cuales se aplicó un formulario en línea. Los datos se sometieron a análisis de contenido. Los resultados indican una identidad profesional saliente en cuanto a la evaluación psicológica y la interdisciplinariedad, pero también crisis de identidad en relación con las prácticas de verificación. Tales resultados señalan la importancia de que la categoría participe en la construcción de sus propias atribuciones.(AU)

A relação com o saber nas atividades lúdicas escolares / The relationship with knowledge in school recreational activities / La relación con el saber en las actividades lúdicas escolares

O brincar é uma atividade importante para o desenvolvimento infantil, porque melhora aspectos cognitivos, emocionais e físicos. Além disso, jogos e brincadeiras podem ser explorados como recurso educacional. Partindo do entendimento da ludicidade enquanto um processo subjetivo, este trabalho investigou a relação com o saber estabelecida durante as brincadeiras, buscando compreendê-las em suas dimensões epistêmica, social e identitária. Dezesseis estudantes do 5º ano do ensino fundamental foram entrevistados a partir de um roteiro baseado no instrumento "balanço do saber", proposto por Bernard Charlot. As questões foram adaptadas para possibilitar apreender o que as crianças dizem aprender durante as brincadeiras em que participam, com ênfase naquelas realizadas em sala de aula. Os resultados da análise de conteúdo realizada mostraram que, apesar de existirem conflitos sobre como se estabelecem as funções lúdica e educativa, quando a brincadeira infantil é utilizada como recurso pedagógico, os sujeitos podem identificar benefícios no processo de aprendizagem por meio dela. Aponta-se, também, a necessidade de considerar a condição social da criança no ambiente escolar para o sucesso ao utilizar essas atividades como práticas pedagógicas.(AU)

Child's play is an important activity for child development since it improves cognition, emotional, and physical aspects. Games can also be explored as an educational resource. Starting from the understanding that playfulness is a subjective process, this work has investigated the relationship to the knowledge stablished during games, aiming to understand it in its epistemic, social, and identitary dimensions. A group of 16 5th grade students were interviewed from a script based on the instrument "balance of knowledge," as proposed by Bernard Charlot. The questions were adapted to enable the apprehension of what children say they learn on the games they play, emphasizing those which are played in classrooms. The results of the content analysis performed have showed that, despite the conflicts on how both playful and educative functions are stablished when child's play is used as a pedagogic resource, the subjects can identify benefits on the process of learning with it. The need to consider the child's social condition in the school environment to reach success when using these activities as pedagogical practices is also pointed out.(AU)

Jugar es una actividad importante para el desarrollo de los niños, porque mejora aspectos cognitivos, emocionales y físicos. Por tanto, los juegos son explorados como recurso educativo. Partiendo de la comprensión de que lo lúdico es un proceso subjetivo, este trabajo analizó la relación con el saber que se establece durante el juego, con el objetivo de comprenderlo en sus dimensiones epistémica, social e identitaria. Se entrevistó a dieciséis estudiantes de quinto grado a partir de un guion basado en el instrumento "balance del saber" propuesto por Bernard Charlot. Las preguntas fueron adaptadas para permitir la aprehensión de lo que los niños dicen que aprenden en sus juegos, enfatizando los que se juegan en las aulas. Los resultados del análisis de contenido realizado mostraron que, a pesar de que existen conflictos sobre cómo se establecen ambas funciones lúdica y educativa cuando se utiliza el juego infantil como recurso pedagógico, los niños pueden identificar beneficios en el proceso de aprendizaje a través del juego. Se señala la necesidad de considerar la condición social del niño en el entorno escolar para alcanzar el éxito al utilizar estas actividades como prácticas pedagógicas.(AU)

Sober Curiosity: A Qualitative Study Exploring Women's Preparedness to Reduce Alcohol by Social Class.

BACKGROUND: Urgent action is required to identify socially acceptable alcohol reduction options for heavy-drinking midlife Australian women. This study represents innovation in public health research to explore how current trends in popular wellness culture toward 'sober curiosity' (i.e., an interest in what reducing alcohol consumption would or could be like) and normalising non-drinking could increase women's preparedness to reduce alcohol consumption. METHODS: Qualitative interviews were undertaken with 27 midlife Australian women (aged 45-64) living in Adelaide, Melbourne and Sydney in different social class groups (working, middle and affluent-class) to explore their perceptions of sober curiosity. RESULTS: Women were unequally distributed across social-classes and accordingly the social-class analysis considered proportionally the volume of data at particular codes. Regardless, social-class patterns in women's preparedness to reduce alcohol consumption were generated through data analysis. Affluent women's preparedness to reduce alcohol consumption stemmed from a desire for self-regulation and to retain control; middle-class women's preparedness to reduce alcohol was part of performing civility and respectability and working-class women's preparedness to reduce alcohol was highly challenging. Options are provided for alcohol reduction targeting the social contexts of consumption (the things that lead midlife women to feel prepared to reduce drinking) according to levels of disadvantage. CONCLUSION: Our findings reinstate the importance of recognising social class in public health disease prevention; validating that socially determined factors which shape daily living also shape health outcomes and this results in inequities for women in the lowest class positions to reduce alcohol and related risks.

Hospital Discharge as a Locus for Curiosity, Affirmation, and Advocacy.

Acknowledging the "dignity of risk" in hospital discharge planning requires a determination to work towards serious change in the livability and healthfulness of our communities, balanced with a positive affirmation of patients' resourcefulness and enmeshment in networks of coping and care. Unfortunately, when clinicians err single-mindedly towards either extreme, we can perpetuate harm, either by unwitting reenactment of structural power dynamics already present in patients' lives or by failures of curiosity that miss opportunities to uncover resources and supports. This article explores two clinical vignettes involving patient-doctor discordance over hospital discharge preferences in the context of patient risk. By shifting these scenarios away from principlist conflicts between the physician's duty to act beneficently and yet uphold patient autonomy-narratives which center the clinician as primary ethical agent-this article recenters the patient as chief protagonist undertaking the dignity of risk. Through conceptual explorations of structural competency, strengths-based approaches to individuals and communities, and the notion of abundance as a catalyst for imaginative redesign of health (in)equities as we currently find them, this article envisions patient "risk" as an activating state, one capable of inspiring the clinician to undertake a historically and socially informed, structure- and solution-oriented practice.

Is economic risk proneness in young children (Homo sapiens) driven by exploratory behavior? A comparison with capuchin monkeys (Sapajus apella).

Economic risk proneness is displayed by human children and some nonhuman primate species. To explore the role of attraction toward the unknown and the unexpected in economic choices, 2.5-year-old children and capuchin monkeys were presented in Experiment 1 with a gambling task in which participants had to choose between 2 options, a secure option and a risky option characterized by an unexpected event. In contrast to capuchins, toddlers showed a strong preference for the risky option over the safe option. In Experiment 2, toddlers maintained their risky choices despite the increased salience of the safe option. In contrast to toddlers, capuchins preferentially chose the safe option in this second experiment. We argue that capuchins' risk aversion reflects an exploitation strategy of known and safe options. In human children, the attractiveness of uncertain reward appears to be linked to their novelty seeking. We argue that toddlers' risk proneness in the gain domain reflects an exploratory search strategy. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The 4-Hole-Board Test for Assessment of Long-Term Spatial Memory in Mice.

The hole-board test has been used in rodents since the early 60s to measure exploratory behavior, locomotor activity and cognitive function. The test is based on rodents' natural curiosity and attraction for novelty. Basically, the hole-board consists of a small square arena with an extractable platform as floor, which has a set of equally spaced circular holes on its surface. In this article, we describe the protocol of a 4-hole-board test allowing the assessment of long-term spatial memory in mice without the employment of water or food restriction, painful stimuli (as electrical shocks) or any aversive condition (as forced swimming or exposure to intense light). Four holes are present on the floor of the square arena (one for each of its four quadrants). Mice released in the arena spontaneously approach the holes and explore them by briefly inserting the snout inside, a behavior defined as nose-poking (or head-dipping). If, after 24 hr, rodents are re-exposed to the hole-board, the novelty of the holes decreases. Animals with an intact long-term memory will show a reduction of the frequency of nose-poking into the holes. The total number of nose-pokes on day 1 is an index of exploration, while the percentage of decrease in nose-poking on day 2 represents an index of long-term spatial memory. Number of quadrant crossings is scored as a control measure for locomotor activity, which with the present protocol should remain stable across the days of testing. Indeed, the 4-hole-board test represents a stress-free and animal-friendly option to evaluate long-term spatial memory. In the present paper, we provide detailed description of the hole-board apparatus and step-by-step protocol for assessment of spatial memory in mice. © 2021 Wiley Periodicals LLC.

Online housing search: A gravity model approach.

In this paper we apply a gravity framework to user-generated data of a large online housing market platform. We show that gravity describes the patterns of inflow and outflow of hits (mouse clicks, etc.) from one municipality to another, where the municipality of the user defines the origin and the municipality of the property that is viewed defines the destination. By distinguishing serious searchers from recreational searchers we demonstrate that the gravity framework describes geographic search patterns of both types of users. The results indicate that recreational search is centered more around the user's location than serious search. However, this finding is driven entirely by differences in border effects as there is no difference in the distance effect. By demonstrating that geographic search patterns of both serious and recreational searchers are explained by their physical locations, we present clear evidence that physical location is an important determinant of economic behavior in the virtual realm too.

Toward evidence-based severity assessment in mouse models with repeated seizures: I. Electrical kindling.

OBJECTIVE: Ethical decisions about an allowance for animal experiments need to be based on scientifically sound information about the burden and distress associated with the experimental procedure and models. Thereby, species differences need to be considered for recommendations regarding evidence-based severity assessment and refinement measures. METHODS: A comprehensive analysis of behavioral patterns and corticosterone or its metabolites in serum and feces was completed in kindled mice. The impact of kindling via two different stimulation sites in the amygdala and hippocampus was determined. Data were compared to those from naive and electrode-implanted groups. RESULTS: Amygdala and hippocampus kindled mice exhibited comparable behavioral patterns with increased activity in the open field, reduced anxiety-associated behavior in the elevated-plus maze, and increased anhedonia-associated behavior in the saccharin preference test. In addition, repeated stimulation of the hippocampus caused a reduction in burrowing behavior and an increase in active social interaction. Levels of corticosterone and its metabolites were not altered in serum or feces, respectively. A comparison of mouse data with findings from amygdala kindled rats confirmed pronounced species differences in behavioral patterns associated with the kindling process. SIGNIFICANCE: Taken together the findings suggest a severity classification for the mouse kindling paradigms as moderate regardless of the stimulation site. The outcome of the species comparison provides valuable guidance for species selection for studies exploring behavioral comorbidities. In this context, it is emphasized that the mouse kindling paradigms seem to be well suited for studies exploring the link between ictal events and network alterations on the one hand, and hyperactivity and anhedonia-associated behavior on the other hand. Moreover, the underlying pathophysiological mechanisms and the impact of therapeutic interventions on these behavioral alterations can be studied in these paradigms providing guidance for the clinical management of respective psychiatric comorbidities in patients.

The Lure of Counterfactual Curiosity: People Incur a Cost to Experience Regret.

After you make a decision, it is sometimes possible to seek information about how things would be if you had acted otherwise. We investigated the lure of this counterfactual information, namely, counterfactual curiosity. In a set of five experiments (total N = 150 adults), we used an adapted Balloon Analogue Risk Task with varying costs of information. At a cost, people were willing to seek information about how much they could have won, even though it had little utility and a negative emotional impact (i.e., it led to regret). We explored the downstream effects of seeking information on emotion, behavior adjustment, and ongoing performance, showing that it has little or even negative performance benefit. We also replicated the findings with a large-sample (N = 361 adults) preregistered experiment that excluded possible alternative explanations. This suggests that information about counterfactual alternatives has a strong motivational lure-people simply cannot help seeking it.

Without Systems and Complexity Thinking There Is no Progress - or Why Bureaucracy Needs to Become Curious Comment on "What Can Policy-Makers Get out of Systems Thinking? Policy Partners' Experiences of a Systems-Focused Research Collaboration in Preventive Health".

The bureaucracy's goal is to maintain uniformity and control within discrete areas of activity and relies on hierarchical processes and procedural correctness as means to suppress autonomous decision making. That worldview, however, is unsuited for problem solving of real world VUCA (Volatility, uncertainty, complexity and ambiguity) problems. Solving wicked problems in the VUCA world requires curiosity, creativity and collaboration, and a willingness to deeply engage and an ability to painstakingly work through their seemingly contradictory and chaotic pathways. In addition, it necessitates leadership. Leaders require a deep - indeed academic - understanding of the nature of the problems and the veracity of various problem-solving approaches. Leadership after all means "[facilitating] the necessary adaptive work that needs to be done by the people connected to the problem." That are the people at the coalface who understand and have to manage the complexities relating to problems unique to their local environment for which of the shelf solutions never work. Systems and complexity thinking is more than a tool, it is - in a sense - a way of being, namely deeply interested in understanding the highly interconnected and interdependent nature of the issues affecting our life and work. Hence, system and complexity thinking is, contrary to what Haynes and colleagues state in their "summation for the public reader," neither "overwhelming and hard [nor difficult] to use practically." Such a view is as much misleading as self-defeating.

The rise to dominance of genetic model organisms and the decline of curiosity-driven organismal research.

Curiosity-driven, basic biological research "…performed without thought of practical ends…" establishes fundamental conceptual frameworks for future technological and medical breakthroughs. Traditionally, curiosity-driven research in biological sciences has utilized experimental organisms chosen for their tractability and suitability for studying the question of interest. This approach leverages the diversity of life to uncover working solutions (adaptations) to problems encountered by living things, and evolutionary context as to the extent to which these solutions may be generalized to other species. Despite the well-documented success of this approach, funding portfolios of United States granting agencies are increasingly filled with studies on a few species for which cutting-edge molecular tools are available (genetic model organisms). While this narrow focus may be justified for biomedically-focused funding bodies such as the National Institutes of Health, it is critical that robust federal support for curiosity-driven research using diverse experimental organisms be maintained by agencies such as the National Science Foundation. Using the disciplines of neurobiology and behavioral research as an example, this study finds that NSF grant awards have declined in association with a decrease in the proportion of grants funded for experimental, rather than genetic model organism research. The decline in use of experimental organisms in the literature mirrors but predates the shift grant funding. Today's dominance of genetic model organisms was thus initiated by researchers themselves and/or by publication peer review and editorial preferences, and was further reinforced by pressure from granting agencies, academic employers, and the scientific community.

[From incidentaloma to secondary discovery]. / De l'incidentalome à la découverte secondaire.

The term incidentaloma, created in 1982, has spread throughout medical literature. However, there does not seem to be a precise definition to describe what an incidentaloma is. In the initial uses, the word incidentaloma systematically designated a mass that was detected during an imaging examination prescribed for diagnostic purposes unrelated to the reason for carrying out the examination. Naming this mass "incidentaloma" did not give any precision on its nature as it can be located in many anatomical zones, secreting or not, benign or malignant, etc. Today, the term "incidentaloma" carries a much broader dimension which seems to cover the notion of incidental discovery, whether radiological, biological or genetic. The evolution of the term "incidentaloma" demonstrates its heuristic nature. It is a sign of a change in modern medicine which hesitates between a patient clinic and a data clinic. Fortuitous discoveries are a phenomenon known and anticipated by radiologists. Thus, these discoveries are no longer fortuitous, or even unexpected, but secondary to the use of health technology.

TITLE: De l'incidentalome à la découverte secondaire. ABSTRACT: Le terme incidentalome, créé en 1982, s'est, depuis, diffusé dans la littérature médicale. Il ne semble cependant pas exister de définition précise pour décrire ce qu'est un incidentalome. Dans les usages initiaux, l'incidentalome désignait une masse détectée à l'occasion d'un examen d'imagerie prescrit à visée diagnostique sans qu'un lien ne soit déterminé avec le motif de réalisation de l'examen. La qualification d'« incidentalome ¼ de cette masse n'apportait aucune précision sur sa nature, celle-ci pouvant être située dans de nombreuses zones anatomiques, être sécrétante ou non, être bénigne ou maligne… Aujourd'hui, le terme d'incidentalome porte une dimension beaucoup plus large, semblant recouvrir la notion de découverte fortuite, qu'elle soit radiologique, biologique ou génétique. Cet usage évolutif du terme démontre son caractère heuristique. Il est le signe d'une modification de la médecine moderne qui hésite entre une clinique des patients et une clinique des données. Les découvertes fortuites sont un phénomène connu et anticipé par les radiologues. Ces découvertes ne sont donc plus fortuites, ni même inattendues, mais bien secondaires à l'usage de la technologie en santé.

An Exploratory Assessment of Epistemic Curiosity in Students at Three Doctor of Pharmacy Programs.

Objective. To determine the level of epistemic curiosity in a sample of student pharmacists from three Doctor of Pharmacy (PharmD) programs as well as any differences in epistemic curiosity levels that exist between programs and with regard to professional year. Methods. Litman's Epistemic Curiosity Scale (ECS) was administered to student pharmacists at three different PharmD programs. Descriptive statistics were calculated, and overall mean ECS scores as well as mean scores on epistemic curiosity motivated by intellectual interest (I-type) and informational deprivation (D-type) were compared among student pharmacists at the three institutions using analysis of variance. Reliability analyses were also performed on the data. Results. A total of 569 out of 1143 eligible students responded to the survey, for an overall response rate of 49.8%. The mean overall ECS score was 27.6 (SD=4.9). Mean I-type epistemic curiosity was 14.9 (SD=2.8) overall, but was statistically different among the schools. Mean D-type epistemic curiosity was 12.7 (SD=3.2) overall, but was statistically similar among the programs. Overall, the data demonstrated good internal consistency, with a Cronbach's alpha of .81. Conclusion. This study was the first to characterize epistemic curiosity in student pharmacists and included data from multiple years and multiple programs. Future analyses should investigate associations between epistemic curiosity and other factors of interest to help elucidate how better understanding epistemic curiosity or enhancing it in student pharmacists may help facilitate student success.

Curious eyes and awkward smiles: Menstruation and adolescent boys in India.

INTRODUCTION: Most Indian studies on menstruation include only girls/women as participants, making it a 'women's' topic. This exclusion of adolescent boys fails to understand menstruation as a social epidemiological entity with existing gender inequalities. For engaging boys to play a meaningful role in improving women's health, studying their knowledge, beliefs regarding topics such as menstruation and socioeconomic characteristics influencing their menstruation-related experiences need attention. Addressing this is an essential step for reducing gender disparities in adolescent health. Thus, we explore boys' knowledge, beliefs and attitudes regarding menstruation and the impact of social determinants on their menstruation-related experiences. METHODS: A sequential mixed-methods study comprising 21 semi-structured interviews, 5 Focus Group Discussions and 12 key respondent interviews; followed by a cross-sectional survey of 744 boys from Nashik district, India was conducted. We employed thematic analysis for qualitative data and multivariable regression to model risk ratios for outcomes. RESULTS: An amalgam of curiosity and awkwardness regarding menstruation was observed. Many lacked accurate knowledge and possessed misinformation. Social and individual-level determinants influenced boys' menstruation related experiences. Fully adjusted models revealed that being admitted in private unaided schools; having mothers with at least a college education; and comfort with teacher positively influenced boys'knowledge, attitudes and beliefs (incidence rate ratios at 95% CI: 2.67 [1.02, 6.95], p < 0 0.05; 3.16 [1.35, 7.38], p < .05 and 1.92 [1.24, 2.99],p < .01, respectively). CONCLUSION: Our study highlights the need of improving Indian boys' understanding and beliefs about menstruation by addressing the social determinants that influence their menstruation-related experiences.

Risk Assessment and the Effects of Refuge Availability on the Defensive Behaviors of the Southern Unstriped Scorpion (Vaejovis carolinianus).

Selection should favor individuals that acquire, process, and act on relevant environmental signals to avoid predation. Studies have found that scorpions control their use of venom: both when it is released and the total volume expelled. However, this research has not included how a scorpion's awareness of environmental features influences these decisions. The current study tested 18 Vaejovis carolinianus scorpions (nine females and nine males) by placing them in circular arenas supplied with varying numbers (zero, two, or four) of square refuges and by tracking their movements overnight. The following morning, defensive behaviors were elicited by prodding scorpions on the chelae, prosoma, and metasoma once per second over 90 s. We recorded stings, venom use, chelae pinches, and flee duration. We found strong evidence that, across all behaviors measured, V. carolinianus perceived prods to the prosoma as more threatening than prods to the other locations. We found that stinging was a common behavior and became more dominant as the threat persisted. Though tenuous, we found evidence that scorpions' defensive behaviors changed based on the number of refuges and that these differences may be sex specific. Our findings suggest that V. carolinianus can assess risk and features of the local environment and, therefore, alter their defensive strategies accordingly.

Costs of exploratory behavior: the energy trade-off hypothesis and the allocation model tested under caloric restriction.

In order to maintain the energy balance, animals often exhibit several physiological adjustments when subjected to a decrease in resource availability. Specifically, some rodents show increases in behavioral activity in response to food restriction; a response regarded as a paradox because it would imply an investment in locomotor activity, despite the lack of trophic resources. Here, we aim to explore the possible existence of trade-offs between metabolic variables and behavioral responses when rodents are faced to stochastic deprivation of food and caloric restriction. Adult BALB/c mice were acclimatized for four weeks to four food treatments: two caloric regimens (ad libitum and 60% restriction) and two periodicities (continuous and stochastic). In these mice, we analyzed: exploratory behavior and home-cage behavior, basal metabolic rate, citrate synthase and cytochrome oxidase c enzyme activity (in liver and skeletal muscle), body temperature and non-shivering thermogenesis. Our results support the model of allocation, which indicates commitments between metabolic rates and exploratory behavior, in a caloric restricted environment. Specifically, we identify the role of thermogenesis as a pivotal budget item, modulating the reallocation of energy between behavior and basal metabolic rate. We conclude that brown adipose tissue and liver play a key role in the development of paradoxical responses when facing decreased dietary availability.
