The Creativity Matrix: Spotlights and Blind Spots in Our Understanding of the Phenomenon

In this paper, we organize past and present theories and models of creativity by using a new conceptual framework—the creativity matrix—with the aim of highlighting the dimensions of creativity we know a lot about and those we tend to either ignore or find difficult to study. This matrix is formed by bringing together a developmental model of creativity (the 4 C's) and a structural one (the 5 A's). We start by briefly describing these two conceptual frameworks, and then, we proceed to exploring the matrix itself by describing how the 5 A's are dynamically organized at each “level” of the 4 C's. Importantly, our overview of the matrix is informed by existing models and concepts that address one of more of the C's and the A's. This gives us a unique opportunity to take stock of what has been studied so far and, toward the end, consider new avenues for the development of theory and research agendas within creativity studies.     

QT & RR variability spots the earliest autonomic deregulation in diabetes

Step 1

Preliminary MANOVA/ANOVA showed significant effects on the ensemble of spectral variables of every single factor (status: normal or patient group; intervention; gender) with no significant factor interactions. Significant effects of intervention or status on main RR spectral variables and on a few QT spectral variables were also documented.

Step 2

Non-parametric tests showed that diabetics had (mildly to moderately) shorter mean RR, while their RR-LF was always singificantly lower than those found in normals—a difference propagated to QT-LF but not to idioventricular QT-LF. In the intra-group there were similar responses to interventions except stress with respect to mean RR. Consistent reduction in RR-LF under moderate or no change in mean RR suggests vagal down-regulation that, judging by idioventricular QT-LF showing, goes perhaps before a similar process with sympathetic control of ventricles. This phase delay may introduce an early arrhythmic risk worth dealing with in secondary prevention.     

Idioventricular low frequency oscillation in QT interval responds univocally to RR confusing kinds of mental stress

Seventeen male subjects, aged nineteen to twenty, went through a protocol including, while supine, relaxation at rest (10 min) and mental stress (MS) by a Kraepelin (arithmetic) test (5 min), as part of a larger study. With a polygraphic analog recording set-up we also collected a 1 ms - digital facsimile of a lead II-like thoracic ECG with maximum T-wave (Codas, Dataq Instr). Twenty-three stress responses were assigned to three classes according to known cardiotacho-, plethysmo-, and pneumo-graphic marks of “concentrated attention mainly,” “emotion,” or still “high emotion.” During each setting the most stationary 3 min RR epoch in cardiotachogram was selected for joint RR & QT beat-by-beat variability study. RR and QT intervals were detected using a published algorithm. Conventional RR and QT Fourier autospectra were computed while using RR^*QT mean square coherence spectrum we detached the RR-independent, idioventricular (IV) fraction of QT low frequency (LF: 0.04–0.15 Hz) power of variability (IV QT-LF). IV QT-LF responded consistently to varieties of mental stress that confuse RR-LF or let QT-LF unchanged, best witnessing the cortically-issued ventricular adrenergic strain. Indeed, while emotion propels the same way all spectral variables above, concentrated attention increased (Wilcoxon) significantly IV QT-LF only (0.54–0.80 ms²) and decreased RR-LF (715–465 ms²). Findings hold promise of a non-invasive, high resolution Holter based monitoring of sympathetic status of myocardium, robust vis-à-vis of confusion caused by the autonomic interplay at sino-atrial node.     

Social Contact,Academic Satisfaction,COVID-19 Knowledge,and Subjective Well-being Among Students at Turkish Universities: a Nine-University Sample

Adverse effects of COVID-19 are seen not only on the physical health of infected individuals but also on their subjective well-being. Sudden changes in social lives, lockdowns, and shifts towards online education have had a negative impact on many people, especially university students. As part of an international study, the current study focused on the well-being of students at Turkish universities in relation to social contact, academic satisfaction, and COVID-19 knowledge. A total of 7363 students from nine universities (86.6% from state universities, 71.04% female, and 73.52% at bachelor’s level) participated in an online survey. Results revealed that females had lower levels of subjective well-being and academic satisfaction. According to a mediation model in the study, the relationship between social contact and well-being was mediated by academic satisfaction and COVID-19 knowledge. Our findings can guide future researchers, mental health professionals, universities, and policymakers to understand and improve subjective well-being of university students.

     

Individual Differences in Antisocial Punishment in Public Goods Situations: The Interplay of Cortisol with Testosterone and Dominance

This research investigates which endocrinological and psychological factors are associated with individuals' tendency to engage in destructive antisocial punishment, that is, to costly punish cooperative individuals in public goods situations. In this work, we focus on the interplay of endogenous cortisol with testosterone and dominance. We applied the dual‐hormone hypothesis according to which testosterone is positively associated with destructive and dominant behavior but only in individuals with low levels of cortisol. Study 1 shows that individuals are more likely to engage in destructive antisocial punishment in a public goods game with the option to punish when their testosterone level is high, given that their level of cortisol is low, which bolsters the dual‐hormone hypothesis. In contrast, no significant interaction effect of testosterone and cortisol emerges for the punishment of uncooperative free‐riders (altruistic punishment). In a second study, we build on these findings and document that self‐reported dominance is only positively associated with antisocial punishment (but not with altruistic punishment) when cortisol is low. In sum, the results indicate the importance of taking endocrinological and psychological factors (and their interactions) into account in order to reach a comprehensive understanding of individuals' behavior in social dilemma situations.

Creativity in Perspective: A Sociocultural and Critical Account

This article starts from the premise that creativity is a social construction and focuses on historical and scientific accounts of this phenomenon. Using a perspectival model in a pragmatist key, it outlines three historical perspectives on creativity—the He-, I-, and We-paradigms—differentiated internally by two positions—artist and engineer. It then argues that, instead of dialogues between perspectives, fruitful for creativity research, we are often facing monological relations. In the end, possibilities for “thirdness” are explored, including the position of the craftsman, in developing a sociocultural as well as critical account of what it means to create.     

驾驶员情绪状态研究

Exposing information sharing as strategic behavior: power as responsibility and “Trust” buttons

Online platforms' success depends on individual's information sharing (IS). However, previous research showed that “knowledge is power” is a default‐perception in organizations and that individuals share relatively unimportant information while keeping the important private information for themselves. Trust has also been identified as important enabler of IS. We examined the role of power construed as responsibility for others' outcomes and of a “Trust” button, a theory‐inspired technological feature, using a 2(Power construals: opportunity vs. responsibility) × 2(Buttons: “Like” vs. “Like‐or‐Trust”) × 2(Information sharedness as within‐subjects factor; public, private) design. Findings showed that construing power as responsibility and “Trust” button's presence increased the sharing of private information; clicking behavior yielded insights into the underlying mechanisms. Theoretical and practical implications are discussed.
