Summary The national lockdown imposed in several countries to counteract the coronavirus disease 2019 (COVID‐19) pandemic led to an unprecedented situation with serious effects on mental health of the general population and of subjects affected by heterogeneous diseases. Considering the positive association between narcoleptic symptoms and creativity, we aimed at exploring the psychological distress associated with COVID‐19 restrictions and its relationship with depressive symptoms and creativity in patients with narcolepsy type 1 (NT1). A total of 52 patients with NT1 and 50 healthy controls, who completed a previous study on creativity, were contacted during the first lockdown period to complete an online survey evaluating psychological distress related to the COVID‐19 outbreak, sleep quality, narcolepsy and depressive symptoms, and creative abilities. The patients with NT1 showed an improvement in subjective sleepiness while controls reported worsening of sleep quality during the lockdown. Depression and NT1 symptom severity proved significant predictors of COVID‐19‐related distress. Creative performance, namely generative fluency, turned out to be a favourable moderator in the relationship between depression and patients’ distress, reducing the detrimental effect of depression on the patients’ wellbeing. On the contrary, creative originality proved to be a disadvantageous moderator in the relationship between NT1 symptom severity and the distress associated with this traumatic event indicating a higher vulnerability to developing COVID‐19‐related distress, particularly evident in patients displaying higher originality. Overall, these results highlight a crucial role of creativity in patients with NT1, suggesting that creative potential could be used as a protective factor against the development of distress associated with the lockdown.

In the Dynamic Creativity Framework creativity is defined as a context-embedded phenomenon requiring potential originality and effectiveness. This definition indicates that the environmental conditions embedding the creative process have fundamental impact on the process itself and its outcomes. In particular, Virtual environments (VEs) are emerging as everyday contexts for a large part of the world population, affecting behaviors and feelings. VEs have been demonstrated to affect creative performance in several ways, even if the psychological mechanisms at the basis of the different modifications in the creative behavior are far from being completely explained. The aim of this study was to explore the influence of different types of VEs on creative performance, with a specific focus on participants’ emotional reactions and on their individual differences in the Openness personality trait. A total of 22 participants were exposed to four different types of environments: a real room environment (RE), a control virtual environment (CVE) resembling the physical characteristics of the RE, a positive virtual environment (PVE) and a negative virtual environment (NVE). Participants were free to explore each environment for two minutes, then they were asked to perform an Alternative Uses Task for five minutes, to measure divergent thinking performance. Openness and affective reactions in each environment were measured in all participants. Results showed that Openness was associated with higher originality of responses and that this effect was particularly significant in PVE. Importantly, the type of environment interacted significantly with participants’ affective reactions in explaining their creative performance, revealing that an increase of ideas originality was associated with an increase of positive affect, emerging as a consequence of experiencing a PVE. Affective reactions to VEs, in combination with individual differences in term of Openness, thus emerge as one of the possible explicatory mechanisms of the impact of virtual reality on creative performance.

Growing neurophysiological evidence points to a role of alpha oscillations in divergent thinking (DT). In particular, studies have shown a consistent EEG alpha synchronization during performance on the Alternative Uses Task (AUT), a well-established DT task. However, there is a need for investigating the brain dynamics underlying the production of a sequence of multiple, alternative ideas at the AUT and their relationship with idea originality. In twenty young adults, we investigated changes in alpha power during performance on a structured version of the AUT, requiring to ideate four alternative uses for conventional objects in distinct and sequentially balanced time periods. Data analysis followed a three-step approach, including behaviour aspects, physiology aspects, and their mutual relationship. At the behavioural level, we observed a typical serial order effect during DT production, with an increase of originality associated with an increase in ideational time and a decrease in response percentage over the four responses. This pattern was paralleled by a shift from alpha desynchronization to alpha synchronization across production of the four alternative ideas. Remarkably, alpha power changes were able to explain response originality, with a differential role of alpha power over different sensor sites. In particular, alpha synchronization over frontal, central, and temporal sites was able to predict the generation of original ideas in the first phases of the DT process, whereas alpha synchronization over centro-parietal sites persistently predicted response originality during the entire DT production. Moreover, a bilateral hemispheric effect in frontal sites and a left-lateralized effect in central, temporal, and parietal sensor sites emerged as predictors of the increase in response originality. These findings highlight the temporal dynamics of DT production across the generation of alternative ideas and support a partially distinct functional role of specific cortical areas during DT.

Emotional awareness (EA) has been defined as the cognitive skill devoted to the identification and description of one’s own and others’ emotional experiences, an ability that has usually been conceptualized along with the development of cognitive intelligence. Despite this, EA has also been deemed a central constituent of Emotional Intelligence (EI), a construct that captures individual differences in how we perceive, communicate, regulate, and understand our own emotions, as well as the emotions of others. The overlap between the cognitive and the emotional domain in the definition of the EA construct has created several difficulties in both its understanding and its usage, so much so that several questions regarding its nature and structure remain unanswered. The aim of the present work was to test in a unique model the explanatory role of both trait EI and fluid nonverbal intelligence on EA variability in children, controlling for the effect of age, a variable strictly related to cognitive development, as well as gender, which is highly associated with trait EI during childhood. Four hundred and eighty-eight pupils (258 females and 230 males) ranging from 8 to 12 years old completed the Levels of Emotional Awareness Scale for Children, the Trait Emotional Intelligence Questionnaire – Child Form, and a measure of pure non-verbal reasoning ability, the Raven’s Progressive Matrices. The results of a structural equation model showed a positive explanatory power of both Raven and TEIQue scores on EA, revealing that both cognitive intelligence and trait EI significantly explained EA. The same model also showed an indirect effect of age, via intelligence scores, on EA, suggesting that the increase of EA with age could be partially imputed to the development of intelligence. Finally, a relation between gender and TEIQue scores confirmed higher trait EI scores in girls than in boys. The implications emerging from this model are discussed.

The present study used a latent variable modelling approach to investigate the influence of motivation on creative achievement in different environments. This was used in conjunction and interaction with other creativity-related predictors, such as openness to new experience and response originality in a divergent thinking task. Specifically, the inside school and the outside school environments were analyzed in a sample of university students. Results showed that the interaction between openness and intrinsic motivation was the strongest predictor of creative achievement. This interaction predicted both outside and inside school creative achievement, which was further influenced by extrinsic tendencies. In particular, intrinsic motivation predicted creative achievement only when associated with a medium or high level of openness to experience. Originality only predicted outside school creative achievement. Limitations and implications of these results are discussed.

We investigated how runners' trait emotional intelligence (trait EI) influences their performance. Participants, recruited the day before a half marathon competition, were asked to report their experience and performance in previous races and to complete a trait EI questionnaire. Through a structural equation modeling approach, we demonstrated that runners' trait EI was the main predictor of runners' finish time. Specifically, trait EI emerged as the variable with the highest power to predict finish time over and above training. Overall, these results are consistent with the explanation that being effective at controlling emotions reduces the impact of fatigue and leads to better performance.

To study whether and how emotion regulation (EmR) strategies are associated with adolescents’ well-being, 633 Italian adolescents completed a survey that measured, using the emotion regulation questionnaire (ERQ), the strategies of cognitive reappraisal (CR) and expressive suppression (ES), and their relationship with several well-being measures. Factor analysis and reliability results confirmed the validity of ERQ to assess adolescents’ regulation strategies. Correlation and regression results showed that a greater reliance on CR was positively associated with better well-being outcomes for most indicators, especially life satisfaction, social support perception, and positive affect; greater preference for ES conversely was associated with lower well-being level for all indicators, including psychological health, emotional loneliness, and negative affect. Neither gender nor age differences were observed for CR and ES; CR and ES were positively correlated with each other. Both analysis of variance and regression results showed gender to be a significant factor for well-being indicators (e.g. males’ higher positive affect and life satisfaction than females’), whereas age was associated with differences in psychological health only, with 16-year olds reporting the lowest health, and 14-year olds the highest. The findings overall show that adolescents’ well-being is related to preferred EmR strategies, mirroring associations found in the adult population. The study results also suggest the need to further explore this relationship in adolescence.

Two studies investigated the effect of trait Emotional Intelligence (trait EI) on people's motivation to help. In Study 1, we developed a new computer-based paradigm that tested participants' motivation to help by measuring their performance on a task in which they could gain a hypothetical amount of money to help children in need. Crucially, we manipulated participants' perceived efficacy by informing them that they had been either able to save the children (positive feedback) or unable to save the children (negative feedback). We measured trait EI using the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF) and assessed participants' affective reactions during the experiment using the PANAS-X. Results showed that high and low trait EI participants performed differently after the presentation of feedback on their ineffectiveness in helping others in need. Both groups showed increasing negative affective states during the experiment when the feedback was negative; however, high trait EI participants better managed their affective reactions, modulating the impact of their emotions on performance and maintaining a high level of motivation to help. In Study 2, we used a similar computerized task and tested a control situation to explore the effect of trait EI on participants' behavior when facing failure or success in a scenario unrelated to helping others in need. No effect of feedback emerged on participants' emotional states in the second study. Taken together our results show that trait EI influences the impact of success and failure on behavior only in affect-rich situation like those in which people are asked to help others in need.

One-pot three-component regioselective azide-alkyne cycloadditions are central reactions for synthesizing pharmaceuticals and fine chemicals and are also applied for in vivo metabolic labeling biotechnology. Homogeneous catalysts based on copper species coordinated with ancillary ligands are regularly used to perform this reaction, offering superior catalytic activity and selectivity compared to conventional heterogeneous counterparts based on supported copper nanoparticles. However, the challenge of catalyst recovery limits the use of these homogeneous compounds in many large-scale applications. In this work, we report the high catalytic performance of a family of Cu-based single-atom catalysts for triazole synthesis, with an emphasis on the fundamental understanding of the structure and function of the catalyst. The catalysts were prepared via tricyanomethanide polymerization to create a joint electronic structure where the mesoporous graphitic carbon nitride carrier acts as a ligand for the atomically dispersed copper species. The material properties and the precise metal location/coordination (i.e., deposited in the heptazine pore of carbon nitride, substituted in the framework of carbon nitride, hosted in a vacancy, or entrapped in sandwich-like arrangement) were characterized through a battery of spectroscopic and theoretical methods. The catalysts were employed in the synthesis of 1,2,3-triazoles employing azide-alkyne click reaction under base-free conditions. The single-atom Cu catalysts demonstrated improved activity and selectivity compared to the homogeneous reference catalyst. Density functional theory calculations corroborated the results and showed that the reaction proceeds through a barrier given by the activation of the acetylenic moiety on Cu1. The activity of this step was primarily affected by the coordination of the metal with the support. Therefore, understanding the metal coordination in single-atom catalysts is critical to further optimizing single-atom catalysts and greening synthetic chemistry.

The aim of the study was to explore whether the acoustic startle response shows signs of early lateralisation. Using non-invasive startle measurements (Automated Infant Motor Movement Startle Seat and Facial Action Coding System), an analysis of response latencies and intensities on the right and left body sides was performed, investigating the presence of asymmetries on the whole-body startle and on the facial component of the startle motor pattern in a group of 5-month-old infants. The findings suggest that the infant whole-body startle is a lateralised response, characterised by a right bias latency. This lateralisation could reflect an underlying lateralised organisation of the infant startle neural circuitry. On the other hand, the analysis of the facial component of the startle motor pattern did not reveal any significant asymmetry. The discrepancy found in the whole-body response and in the startle facial component will be discussed, reflecting on the limits of the adopted methodologies. The use of a high-speed camcorder might allow future research to analyse more in depth the startle fast face responses. ©2013 Taylor & Francis.

Donations in support of a charitable cause can create a conflict between moral intuitions (e.g., fulfilling moral obligations and helping as many individuals in need as possible) and the cost entailed by following one's moral intuitions (e.g., spending money). The present paper investigates this conflict by putting people in a situation in which they must choose whether to help three women by giving more money or help one woman by giving less. In addition, the paper uses the attraction effect paradigm to counteract the single victim effect and reduce the conflict. Experiment 1 demonstrates that in a two-alternative context the majority of participants choose to help one woman by giving €150 instead of helping three women by giving €450. Experiment 2 replicates this finding and highlights the role of emotion regulation strategies in the management of the emotional conflict arising in the two-alternative condition. In both studies, the introduction of a third, dominated alternative reduces the conflict and makes it easier to choose the programme asking for a higher donation and helping three women. Implications for charitable donations and the role of the conflict between moral intuitions and economic costs are discussed. © 2012 Copyright Psychology Press Ltd.

The present study investigated whether three methodologies currently used in animal as well as human adult startle research could be adapted for measuring the startle response in 5-month-old infants. The three methods performed: an automated and computerized recording of the infants' whole-body motor reactions (Automated Infant Motor Movement Startle Seat, AIMMSS); a coding of the infants' facial muscular contractions involved in the startle response (FACS, Baby FACS); an analysis of the infants' eyeblink intensity in response to the startle probes (Eye-Blink Strength scale). The results showed that these methods accurately registered the latency and intensity parameters of the reactions to acoustic startle stimuli. A correlational analysis showed, also, that the three methods registered the same motor reaction measuring the infant acoustic startle response in a consistent way. © 2011 Wiley Periodicals, Inc.

Two nanocomposites of different layer thicknesses were synthesized by impregnation of a rutile titania support with a reduced ceria solution. An in situ diffuse reflectance infrared fourier-transform spectroscopy-mass spectrometry study of these materials, compared with the parent single oxides, has shown remarkable differences in the interaction with ethanol depending on the layer thickness and the environment (oxidizing/reducing). Under anaerobic conditions, it was found that the surface-support interaction stabilized the ceria in the reduced form (Ce3+) in a wide range of temperature. The intrinsic characteristics of these materials were proven useful in the dehydrogenation of ethanol to acetaldehyde at low temperature since they inhibited further oxidation products (typical in the case of bulk ceria) and dehydration products (such as ethylene, the main product for bulk titania), and even promoted aldolic condensation to crotonaldehyde due to their modified acid/base properties. Interestingly, this highly selective oxidation is obtained without the need of using expensive noble metals as catalysts or hydrogen to keep the ceria reduced.

Why are some individuals able to generate outstanding creative products despite repeated frustrating failures? This question has persisted across the centuries and deals with the nature of creativity itself. We hypothesize that the attitude characterizing how people experience and regulate their emotions (i.e., trait emotional intelligence; trait EI) can explain the differences emerging in creative performance under frustration or success. We explored this hypothesis by inducing, through artificial evaluations during a creative task, either creative frustration or creative success, and by measuring changes in attentional and affective processing through eye-tracking. We expected that trait EI, through a moderation of the attentional and affective components defining the creative process, could predict creative performance. Results supported our expectation, showing that through the regulation of the affect experienced during the creative process, trait EI allows the best use of the attentive and affective resources beneficial to creative thinking.

Central disorders of hypersomnolence (CDH) are characterized by excessive daytime sleepiness not related to comorbid sleep or medical disturbances. We systematically examined scientific literature on cognitive functions in patients suffering from CDH. Forty-eight studies proved eligible and were analyzed separately for Narcolepsy Type 1 (NT1), Narcolepsy Type 2 (NT2), Idiopathic hypersomnia (IH) and Kleine-Levin syndrome (KLS). Results were grouped into the cognitive domains of attention, memory, executive functions and higher order cognition. Consistent attention impairments emerged in NT1, NT2 and IH patients, with NT1 patients showing the most compromised profile. Memory functions are largely unimpaired in CDH patients except for KLS patients who display memory deficit. Executive functions and higher-order cognition have been assessed in NT1 while they received little-to-no attention in the other CDH. NT1 patients display high performance in executive functions but exhibit a complex pattern of impairment in higher-order cognition, showing poor decision-making and impaired emotional processing. Moreover, NT1 patients show increased creative abilities. Assessing and monitoring cognitive impairments experienced by CDH patients will allow the design of personalized interventions, parallel to pharmacological treatment, aimed at improving daytime functioning and quality of life of these patients.

Emotional intelligence (EI) is here analyzed as a construct referring to the individual differ- ences in perceiving, regulating, managing, and exploiting emotions, assuming in particular a trait approach to the exploration of the phe- nomenon. Speci!cally, the role of trait EI in the de!nition of the possible in space and in time is addressed, analyzing how individual differences in the management and use of emo- tions can explain the emerging of different pasts, different futures, as well as different possible worlds. Moreover, the role of trait EI in the expression of the individual potential is explored, taking as example two research topics (i.e., prosocial behavior and creative performance) to understand how emotional intelligence can help in understanding the emerging of possible selves. Finally, future possible research scenarios are offered to explore the use of trait EI as a study variable in the investigation of the possible.

The development of catalysts for the hydrogen evolution reaction is pivotal for the hydrogen economy. Thin iron films covered with monolayer graphene exhibit outstanding catalytic activity, surpassing even that of platinum, as demonstrated by a method based on evaluating the noise in the tunnelling current of electrochemical scanning tunnelling microscopy. Using this approach, we mapped with atomic-scale precision the electrochemical activity of the graphene–iron interface, and determined that single iron atoms trapped within carbon vacancies and curved graphene areas on step edges are exceptionally active. Density functional theory calculations confirmed the sequence of activity obtained experimentally. This work exemplifies the potential of electrochemical scanning tunnelling microscopy as the only technique able to determine both the atomic structure and relative catalytic performance of atomically well-defined sites in electrochemical operando conditions and provides a detailed rationale for the design of novel catalysts based on cheap and abundant metals such as iron. Establishing structure–activity relationships is crucial for the design of improved catalysts. Now, by developing a method based on electrochemical scanning tunnelling microscopy, the active sites of graphene/iron/platinum interfaces are visualized with atomic-scale precision in real time during the hydrogen evolution reaction.

The aim of the present study was to explore the role of narcolepsy symptoms (presence and severity) in predicting creativity.Patients and Methods: Sixty-six consecutive type 1 narcolepsy patients (mean age 38.62 ± 17.05, 31 females) took part in this study. Creative achievement in different life domains and creative beliefs were assessed by a self-reported questionnaire and a scale measuring the creative self, respectively; creative performance was measured through a divergent thinking test (generation of alternative original solutions to an open problem).Results: We found a key effect of hypnagogic hallucinations in modulating creative behaviour. We therefore tested at first whether hypnagogic hallucinations could interact with specific mental states associated with creativity and in particular mind wandering, a factor associated with both creative performance and achievement. Secondly, we verified if hypnagogic hallucinations could influence the definition of creative identity in type 1 narcolepsy patients, which in turn could predict their creative achievement and creative performance. Results showed that spontaneous mind wandering influenced creative achievement through a moderation effect of sleep paralysis and hypnagogic hallucinations. Moreover, sleep paralysis and hypnagogic hallucinations indirectly influenced, through creative identity, both creative achievement and performance (fluency score).Conclusion: Our results highlight the role of hypnagogic hallucinations in triggering the process of mind wandering which leads to greater creative success. In addition, this symptom affects creative identity in narcolepsy, leading in turn to higher creative success and creative potential of narcoleptic patients.Keywords: narcolepsy type 1, creativity, hypnagogic hallucinations, daydreaming, mind wandering

Global and local climate change increases the occurrence and the magnitude of extreme phenomena, as urban heat island and heat waves. These phenomena seriously affect the quality of life in several aspects: society, health, environment; they also heavily affect the building sector, increasing the energy use for cooling and deteriorating the indoor thermal environment. This paper utilizes data from a continuous urban microclimatic monitoring over three years to quantify the impact of heat waves on the thermal quality of two reference residential buildings in the city of Rome, Italy. The synergic effect of heat waves with the urban heat island is also analysed. The observation period includes summers of 2015, 2016 and 2017. The buildings’ response is analysed through numerical thermal analyses in transient regime, taking into account several variants: thermal insulation, mechanical cooling system and thermal free-floating conditions, with different night ventilation strategies. Results show that daily average temperature and urban heat island intensity increase by up to 4.3 °C and 1.5 °C respectively during the heat waves with respect to the rest of the summer. The building cooling energy use rises up 87% during heat wave periods, while average operative temperature in free-running buildings increments by up to 3.5 °C. Results also show the impressive combined impact of heat wave and heat island: triplication of cooling energy use in the worst case and increase of the average operative temperature above 5 °C.

Related research Mindful creativity: The influence of mindfulness meditation on creative thinking Article Full-text available January 2014 Download View more Abstract Mindfulness as a multifaceted construct refers to the ability to regulate with awareness the focus of the attention in the present moment with an open attitude to accept the experience. Originally stemming from Buddhist meditation traditions, this construct has received a great deal of attention in medicine, psychology and neuroscience. Globally, mindfulness-based interventions have been associated with a wealth of psychological benefits, ranging from a decrease of stress and distress and improvement of well-being. A convincing evidence of a close relationship between creativity and mindfulness emerges from the literature as well. Specifically, the two main approaches in the study of the mindfulness-creativity link are here taken into consideration: the study of mindfulness as a unitary construct, which leads to a uniform analysis of mindfulness in association with creativity; the study of the multifold nature of mindfulness, which led to the exploration, through a differential analysis, of the strength and direction of the associations between the mindfulness sub-dimensions and creativity.

The Openness trait is a core dimension in the Big-Five model of personality. The relationship between Openness and creativity is discussed regarding creative potential versus achievement, self-assessed versus others-assessed measures, and implications for creative self-beliefs. Underlying mechanisms that justify the relationship between Openness and creativity are reported, including cognitive, cerebral, emotional, and motivational mechanisms. Socio-cultural implications on personality traits and creativity are taken into consideration, including aspects related to individualist versus collectivist cultures, as well as domain generality across fields of artists and scientists. The entry concludes with a discussion of Leonardo da Vinci, a prime example of Openness.

EEG alpha synchronization, especially in posterior parietal cortical regions of the right hemisphere, is indicative of high internal processing demands that are typically involved in divergent thinking (DT). During the course of DT, as ideation proceeds, ideas tend to become more creative, being more likely to be drawn from new conceptual categories through the use of the cognitive mechanism of flexibility. The present study investigated whether EEG alpha synchronization can be modulated by flexibility in DT by comparing cortical activation patterns during the switch of category (switching) and the stay in the same category (clustering). Twenty participants were required to generate alternative uses of everyday objects during EEG recording. Differential results were specifically found in the lower alpha band (8–10 Hz): whereas clustering showed synchronization typically lateralized in the right posterior parietal areas, switching induced posterior parietal synchronization over both right and left hemispheres. These findings indicate that the two distinct cognitive mechanisms subsuming flexibility (switching and clustering) are associated with a different hemispheric modulation of lower alpha activity, as switching, in comparison to clustering, is related to higher power in the lower alpha band over the left hemisphere. Switching in comparison to clustering may thus require a larger investment of cognitive resources due to the exploratory process of moving from one semantic conceptual category to another in the course of creative ideation.

By means of a combination of surface-science spectroscopies and theory, we investigate the mechanisms ruling the catalytic role of epitaxial graphene (Gr) grown on transition-metal substrates for the production of hydrogen from water. Water decomposition at the Gr/metal interface at room temperature provides a hydrogenated Gr sheet, which is buckled and decoupled from the metal substrate. We evaluate the performance of Gr/metal interface as a hydrogen storage medium, with a storage density in the Gr sheet comparable with state-of-the-art materials (1.42 wt %). Moreover, thermal programmed reaction experiments show that molecular hydrogen can be released upon heating the water-exposed Gr/metal interface above 400 K. The Gr hydro/dehydrogenation process might be exploited for an effective and eco-friendly device to produce (and store) hydrogen from water, i.e., starting from an almost unlimited source.

For a long time, mainstream psychological research on cognitive pro- cesses has been focused on the investigation of externally-oriented cognition, namely deliberate processes generated in response to cues provided by the experi- menter and associated with specific experimental paradigms. During the last two decades, there has been a surge of interest in both psychology and neuroscience toward the investigation of internally-oriented cognition, and, among the different kinds, a growing interest has been devoted to mind wandering (MW), which repre- sents a shift in the contents of thought away from an ongoing task and/or from events in the external environment, toward internal mental contents. By definition, MW is characterized by a flow of thought, and it occurs without a fixed course or a drive to reach a specific goal. Creative thinking also involves dynamic shifts between different information and mental states. Does mind wandering contribute to creativ- ity? Here we briefly review mixed findings on the association between MW and creativity and we outline a new multidimensional dynamic approach, in which the associations between different kinds of MW (i.e. spontaneous and deliberate) and different forms of creativity are considered. Practical implications of this approach are discussed.

The interaction of emotions with creative cognition is one of the most intriguing topics in the creativity research. In this study, we investigated the extent to which various emotional states influence the evaluation of ideas, which is a crucial component of the creative thinking process. To this end, we used emotional (both positive and negative) and neutral pictures to induce emotional states and then asked participants to evaluate the creativity of exogenous ideas (i.e., those generated by other people) as part of an alternative use evaluation task. As the results of previous studies suggest the existence of a negative bias when judging highly creative ideas, we presented the participants with non-creative, moderately creative, and highly creative uses for everyday objects. Overall, the participants gave higher creativity ratings when under positive emotional engagement than when in negative or neutral conditions. Moreover, neutral and emotional context differently moderated the creativity evaluation of the three object use categories. Specifically, participants gave higher ratings for non-creative uses, and (to a lesser extent) for highly creative uses when in a positive emotional state, than they did when in the neutral condition. On the other hand, when in a negative emotional state, the participants gave lower ratings for moderately creative uses than they did in either the positive or neutral conditions. These data provide initial evidence that emotional states can influence the creativity evaluation of exogenous alternative ideas that are generated through divergent thinking.

The interactive relationship between the individual and the social constituents of the creative process emerges strongly during the evaluation of the outcomes of the process. In fact, the contrast with social and cultural norms depicting the originality and effectiveness of an idea brings into the creative process a high level of affective arousal, that can be either beneficial or detrimental to the creative process. Why are some people more able to face this contrast and to resist the frustration arising from repeated negative evaluation is the issue addressed in a recent study, summarized in this chapter. Specifically, the study focused on the analysis of the individual differences defining creative performance during situations of creative frustration and creative success. In particular, the differences in the ability to manage attentive and emotional resources, as well as the differences in trait emotional intelligence (trait EI), a personality trait defining the ability to process, use, and manage affect-laden information of an intrapersonal or interpersonal nature, have been explored during these conditions. Results highlighted the central role of trait EI in the management of attentive and affective resources under frustration and success conditions, strongly influencing people’s creative performance. In particular, individual differences in the management of the affective arousal deriving from the contrast with evaluations coming from the external environment emerged to be essential in distinguishing between a successful and an inconclusive creative process.

Graphene-h-BN hybrid nanostructures are grown in one step on the Pt(111) surface by ultra-high vacuum chemical vapor deposition using a single precursor, the dimethylamino borane complex. By varying the deposition conditions, different nanostructures ranging from a fully continuous hybrid monolayer to well-separated Janus nanodots can be obtained. The growth starts with heterogeneous nucleation on morphological defects such as Pt step edges and proceeds by the addition of small clusters formed by the decomposition of the dimethylamino borane complex. Scanning tunneling microscopy measurements indicate that a sharp zigzag in-plane boundary is formed when graphene grows aligned with the Pt substrate and consequently with the h-BN layer as well. When graphene is rotated by 30°, the graphene armchair edges are seamlessly connected to h-BN zigzag edges. This is confirmed by a thorough density functional theory (DFT) study. Angle resolved photoemission spectroscopy (ARPES) data suggests that both h-BN and graphene present the typical electronic structure of self-standing non-interacting materials.[Figure not available: see fulltext.].

The recognition of emotional facial expressions is a central aspect for an effective interpersonal communication. This study aims to investigate whether changes occur in emotion recognition ability and in the affective reactions (self-assessed by participants through valence and arousal ratings) associated with the viewing of basic facial expressions during preadolescence (n = 396, 206 girls, aged 11–14 years, Mage = 12.73, DS = 0.91). Our results confirmed that happiness is the best recognized emotion during preadolescence. However, a significant decrease in recognition accuracy across age emerged for fear expressions. Moreover, participants' affective reactions elicited by the vision of happy facial expressions resulted to be the most pleasant and arousing compared to the other emotional expressions. On the contrary, the viewing of sadness was associated with the most negative affective reactions. Our results also revealed a developmental change in participants' affective reactions to the stimuli. Implications are discussed by taking into account the role of emotion recognition as one of the main factors involved in emotional development.

Even if mind wandering (MW) and mindfulness have traditionally been intended as separate and antithetical constructs, the roles of these 2 mental states on creative behavior were jointly explored in this article. In particular, MW was analyzed in light of a recent approach suggesting a differentiation between deliberate and spontaneous MW, whereas mindfulness was analyzed by distinguishing its 5 different constitutional dimensions: observing, acting with awareness, describ- ing, nonreactivity, and nonjudging. The influence on creativity of these 2 mental states was analyzed using a sample of 77 undergraduate students both on a performance index (i.e., originality) and on a self-report index (i.e., creative achievement). Results showed that MW and mindfulness dimensions predicted creative behavior both alone and in combination, suggesting a complex interdependence between these 2 mental states within the creative thinking process. In particular, the critical importance of distinguishing between deliberate and spontaneous MW was revealed by a final path analysis, which revealed the opposite effects of these 2 dimensions on originality and creative achievement. That is, deliberate MW positively predicted creative performance, whereas spontaneous MW was negatively associated with such performance. Moreover, the nonreactivity and awareness dimensions of mindfulness, the latter in interaction with deliberate MW, emerged as main predictors of response originality. Finally, the describing facet of mindfulness predicted creative achievement both directly and indirectly through an interaction with deliberate MW. The implications emerging from the adoption of a multi-dimensional approach to the analysis of MW and mindfulness in the study of creativity are discussed herein.

Recent research on creative person has been enriched with a new perspective that brings together the study of brain functioning with the analysis of creative mind and creative behaviour. This chapter attempts to contribute to this effort, by reviewing the literature on brain activity and creativity, within the theoretical framework offered by the multivariate approach. According to this approach the multidimensional creative process is conceptualized as the interaction between person-centred factors, such as cognitive abilities, motivational drives, and personality traits, and contextual influences derived from the environment. Using this approach as a unifying theoretical framework, a coherent picture of the neurological phenomenology of creativity is provided. The viewpoint presented in this chapter should motivate investigators to reflect on the creative brain using wide theoretical lenses such as the one offered by the multivariate approach.

Mixed solid system involving cerium and zirconium titanate (ZrTiO4) have been prepared using the sol-gel technique. Both X-ray diffraction and DFT calculations firmly indicate that, till a doping level of 10 mol%, cerium ions are dissolved in the titanate matrix (which has the scrutynite structure, analogous to those of the main TiO2 polymorphs) occupying the cationic sites and progressively altering its cell parameters. Cerium is hosted in the matrix both in the form of Ce4+ and Ce3+ ions (XPS results). The trivalent state seems to be favoured even though the state of the dopant depends on the treatment undergone by the material. DFT calculations describe the intra-band gap states formed in both cases and the strong localisation of the single electron in the case of Ce3+ (4f1). Differently from the case of Ce doped ZrO2, that shows photoactivity in the visible light because of the presence of cerium, the doped titanate is inactive in the same conditions. Under UV–vis illumination charge separation occurs (EPR results) and the low-loading doped systems (0.5%, 1%) form OH radicals, detected by spin trapping, more efficiently than the pristine matrix. The absence of photoactivity in the visible range is interpreted in terms of the detrimental role (charge recombination) played by both the occupied intra-band gap states associated to Ce3+ and the corresponding oxygen vacancies formed in the lattice by charge compensation.

Elemental reorganisation and oxidation state changes of key active sites in Co-Fe spinels are investigated by in situ X-ray photoemission spectroscopy (XPS) and operando X-ray absorption spectroscopy (XAS) under oxygen evolution operating conditions. The combination of the two techniques allows identifying both the surface and bulk modifications on the oxides and relating them to the activity loss during extended cycling. The results show that Co-Fe spinels experience a surface irreversible phase evolution under oxygen evolution reaction (OER) conditions, resulting in the formation of an amorphous layer composed of new stable Co(iii) and Fe(iii) species. Accelerated ageing tests show that the durability, intended as the performance loss during cycling treatments, is not directly related to the structural/chemical stability of the spinels but to the new species formed at the surface due to the electrochemical work. Thus, the material that experienced more significant changes was also the most durable one, demonstrating that the understanding of the chemical and/or structural evolution of the materials during the catalytic process can be the key for the design of highly active and stable catalysts.
