Novelty is a pivotal player in cognition, and its contribution to superior memory performance is a widely accepted convention. On the other hand, mnemonic advantages for familiar information are also well documented. Here, we examine the role of experimental distinctiveness as a potential explanation for these apparently conflicting findings. Across two experiments, we demonstrate that conceptual novelty, an unfamiliar combination of familiar constituents, is sensitive to its experimental proportions: Improved memory for novelty was observed when novel stimuli were relatively rare. (...) Memory levels for familiar items, in contrast, were completely unaffected by experimental proportions, highlighting their insensitivity to list-based distinctiveness. Finally, no mnemonic advantage for conceptual novelty over familiarity was observed even when novel stimuli were extremely rare at study. Together, these results imply that novel and familiar items are processed via partially distinct mechanisms, with novelty not providing a mnemonic advantage over familiarity. (shrink)

We tested whether cognitive fusion impairs emotion differentiation and thereby mediates relations between cognitive fusion and depression and panic symptoms among 55 adults, 50.9% women). Using visual stimuli, we elicited multiple emotion states and measured emotional intensity – the subjective emotion intensity of elicited emotions, as well as emotional differentiation – the degree of co-activation of multiple negative emotions when a specific emotion was elicited. First, as hypothesised, we found that cognitive fusion predicted lower levels of emotion differentiation. In contrast, (...) as hypothesised, these effects were significantly greater than the effects of cognitive fusion on emotion intensity. Second, as predicted, MECA, but not SEI, predicted depression and panic symptoms. Finally, we found that MECA mediated the effects of cognitive fusion on depression and panic symptoms. The present findings contribute novel, preliminary empirical insight into associations between cognitive fusion, impaired emotion differentiation and mental ill-health. (shrink)

Variegated phenotypes often result from chromosomal rearrangements that place euchromatic genes next to heterochromatin. In such rearrangements, the condensed structure of heterochromatin can spread into euchromatic regions, which then assume the morphology of heterochromatin and become transcriptionally inactive. In position‐effect variegation (PEV) therefore, gene inactivation results from a change in chromatin structure. PEV has been intensively investigated in the fruitfly Drosophila, where the phenomenon allows a genetic dissection of chromatin components. Consequently, many genes have been identified which, when mutated, act (...) as dominant modifiers (suppressors or enhancers) of PEV. Data available already demonstrate that genetic, molecular and developmental analysis of these genes provides an avenue to the identification of regulatory and structural chromatin components, and hence to fundamental aspects of chromosome structure and function.

Historic inequities exacerbated by COVID-19 and spotlighted by social justice movements like Black Lives Matter have reinforced the necessity and urgency for societies and organizations to bring healing into focus. However, few integrated models exist within management and organization scholarship to guide practice. In response, our focus aims to unpack how organizations can become healing spaces. This paper offers a holistic definition of healing as the foundation for a new conceptual model of organizations as healing spaces. Drawing upon literature from (...) clinical psychology, social psychology, and political science, we identify four perspectives that address healing in organizational contexts: restorative justice, posttraumatic growth, relational cultural theory, and dignity. These healing modalities represent prominent views of how healing can be achieved at the individual, dyadic, organizational, and societal levels. Synthesizing and building on these perspectives, we develop a typology that illustrates three ways organizations can function as healing spaces — Emergent, Endeavoring, and Exemplifying — representing a range of opportunities for how organizations can better respond to suffering. These spaces of healing are differentiated across seven dimensions, including source of harm, recipients of healing, facilitators of healing, focus of healing, length and strength of organizational attention, process of healing, and activators or enablers of healing. This research contributes to organizational healing research and to nascent social justice discussions in the management literature by exploring a range of opportunities for how organizations can better respond to suffering and substantively contribute to remedying harm from systematic bias against marginalized groups via healing.

The study focuses on the links between gender and national security in the legislative arena in Israel, considering whether men and women legislators prioritize security differently, alongside other thematic policy areas. The centrality of national security issues in Israeli politics makes it a good case study for these questions, as it enhances existing gendered stereotypes. The article examines two competing hypotheses. The first suggests that Israeli female legislators will mostly refrain from addressing national security policy issues, focusing instead on softer (...) policy issues, such as gender equality, education, health, and welfare. The second suggests the opposite, claiming that women legislators in Israel will align themselves with their male counterparts’ set of priorities, focusing heavily on issues related to national security. The study finds support mostly for the former: Israeli female legislators are especially active in policy areas relating to women’s issues and children/family and are less active in regard to national security, a policy area heavily dominated by male legislators.

Humanistic Management and Transformative Service Research literatures share the common goal of addressing the increasingly growing global challenges faced by humanity. Recently, organizations have been called to further engage in social innovation in service in an attempt to address these challenges. However, the existing service literature does not offer explicit processes regarding how to manage these social innovation efforts at the human interaction level. By drawing on both Humanistic Management and Service literatures, this paper develops a conceptual framework to guide (...) the social innovation in service efforts. More specifically, this paper aims to answer a key question of: how can organizations manage human interactions to help maximize social innovation in service outcomes? This paper identifies four foundational values that should be at the core of the proposed processes needed in order to achieve the desired outcomes of SIS. Subsequently, a typology of service organizations is offered with different combinations of processes at the human interaction level, highlighting the synergistic effect of the three identified processes. The proposed framework in this paper is a first step in bridging two disciplines to highlight their potential and role in addressing the global challenges. (shrink)

Natural fluctuations in sustained attention can lead to attentional failures in everyday tasks and even dangerous incidences. These fluctuations depend on personal factors, as well as task characteristics. So far, our understanding of sustained attention is partly due to the common usage of laboratory setups and tasks, and the complex interplay between behavior and brain activity. The focus of the current study was thus to test the feasibility of applying a single-channel wireless EEG to monitor patterns of sustained attention during (...) a set of ecological tasks. An EEG marker of attention (BEI—Brain Engagement Index) was continuously recorded from 42 healthy volunteers during auditory and visual tasks from the Test of Everyday Attention (TEA) and Trail Making Test (TMT). We found a descending pattern of both performance and BEI in the auditory tasks as task complexity increases, while the increase in performance and decrease in BEI on the visual task. In addition, patterns of BEI in the complex tasks were used to detect outliers and the optimal range of attention through exploratory models. The current study supports the feasibility of combined electrophysiological and neurocognitive investigation of sustained attention in ecological tasks yielding unique insights on patterns of sustained attention as a function of task modality and task complexity.
