What Can be Done with an Egg? Creativity,Material Objects,and the Theory of Affordances

This article offers a reflection on the role of material objects in the creative process and explores the potential links between creativity and the theory of affordances (Gibson, 1986 ), conceptualized from a sociocultural perspective. From this standpoint, creativity can be defined as a process of perceiving, exploiting, and “generating” novel affordances during socially and materially situated activities. Illustrations are offered for each of the above from a research project investigating traditional Easter egg decoration activities in rural Romania. This brief case study exemplifies the discovery of existing action potentials, the generation of objects with novel affordances, and the transgression of conventional procedures, all resulting in creative forms of expression. In the end, some conclusions are drawn regarding the ways in which an affordance theory of creativity can enrich our understanding of the phenomenon and contribute to the development of a new program of research concerned with situated and distributed creative acts.     

Encoding Modal Logics in Logical Frameworks

We present and discuss various formalizations of Modal Logics in Logical Frameworks based on Type Theories. We consider both Hilbert- and Natural Deduction-style proof systems for representing both truth (local) and validity (global) consequence relations for various Modal Logics. We introduce several techniques for encoding the structural peculiarities of necessitation rules, in the typed -calculus metalanguage of the Logical Frameworks. These formalizations yield readily proof-editors for Modal Logics when implemented in Proof Development Environments, such as Coq or LEGO.     

Accuracy of Basic Knowledge of Traumatic Historical Events: The Armenian Genocide

This research assumes that accuracy of shared historical knowledge of genocide might help new generations cope with the trauma lived by previous generations, while the longer the denial of a genocide the more fragmented the macronarrative and the longer the collective trauma. The Armenian genocide (1915) is generally represented in opposite ways by the Turks and Armenians. The study explores the knowledge accuracy of the 1915 events before and after the centennial commemoration of the genocide and uses convenience samples from Bulgaria, Czech Republic, Croatia, Romania, United States, Venezuela, and a representative sample (Romania, N = 1231). The major findings suggest a very low basic knowledge of genocide, with a few exceptions, despite a significant increase of this knowledge after the 100-year commemoration.     

Engaged,Committed and Helpful Employees: The Role of Psychological Empowerment

Although previous research has been focused on the relationship among personality, empowerment, and outcomes, little is known about the incremental effect of empowerment on positive work outcomes. This article aims at exploring the relation between personality factors (i.e., extraversion and conscientiousness) and positive work outcomes (i.e., work engagement, affective organizational commitment, and organizational citizenship behavior), and at determining the incremental effect of psychological empowerment on these outcomes. A convenience sample from three organizations has been used for data collection (N = 258; 52% women, mean age 38.55 years, SD = 10.21). Hierarchical multiple regressions indicate that personality and psychological empowerment explain a significant amount of the variance in the positive organizational outcomes, and that psychological empowerment has a significant incremental value over demographics and personality for the studied outcomes.     

Emotion Regulation Strategies,Secondary Traumatic Stress,and Compassion Satisfaction in Healthcare Providers

The aim of the present study is to examine the relationships between two emotion regulation strategies (cognitive reappraisal and expressive suppression), secondary traumatic stress, and compassion satisfaction in a sample of 190 healthcare providers. Another aim of this study is to examine if the relations between emotion regulation strategies and traumatic stress symptoms are moderated by compassion satisfaction. The respondents volunteered to take part in the research and completed self-reporting measures describing the use of emotional regulation strategies, the symptoms of secondary traumatic stress, and the compassion satisfaction. The results revealed negative associations between cognitive reappraisal and secondary traumatic stress, while expressive suppression is positively associated with arousal. Moreover, cognitive reappraisal is positively related to compassion satisfaction, while secondary traumatic stress symptoms are negatively correlated with compassion satisfaction. Furthermore, the relationship between expressive suppression and intrusions is moderated by compassion satisfaction. The implications of these results for enhancing professional quality of life in the context of secondary exposure to traumatic life events are discussed.     

Tailoring Gratitude Interventions. How and for Whom Do They Work? The Potential Mediating Role of Reward Processing and the Moderating Role of Childhood Adversity and Trait Gratitude

Outcomes of gratitude interventions are encouraging, but inconsistent across studies. In addition, both mechanisms of change and effect modifiers for these interventions are largely unknown. Recent data point toward potential candidates and suggest reward processing may be a promising mechanism underlying these interventions, while childhood adversity (CA) and trait gratitude may impact on them. However, existing research aimed at investigating these hypotheses is scarce. Building on these, we examined the effectiveness of a gratitude intervention for decreasing depressive symptoms and negative affect and increasing positive affect. We also investigated changes in reward processing following intervention and explored differences in adherence and drop-out between groups. Finally, we investigated the moderating role of CA and trait gratitude.

Participants (N=237, ages between 18–56) were randomly allocated to a gratitude or active control condition (14 days). Following intervention, findings indicated a significant decrease in depressive symptoms and negative affect in both conditions. While positive affect remained stable, a significant time effect emerged for reward processing. CA severity, but not multiplicity, moderated the effectiveness of the intervention, adherence and drop-out. Trait gratitude moderated the effectiveness of the gratitude intervention only on depressive symptoms.

Gratitude interventions may not be the best fit for everyone. Thus, we recommend tailoring interventions, especially in individuals reporting a history of severe CA.
