Leadership,creativity and innovation: a meta-analytic review

ABSTRACT

This paper reports the most comprehensive meta-analytic examination of the relationship between leadership and both followers’ creative and innovative performance. Specifically, we examined 13 leadership variables (transformational, transactional, ethical, humble, leader-member exchange, benevolent, authoritarian, entrepreneurial, authentic, servant, empowering, supportive, and destructive) using data from 266 studies. In addition to providing robustly estimated correlations, we explore two theoretically and pragmatically important issues: the relative importance of the different leadership constructs and moderators of the relationship between leadership and employee creativity and innovation. Regrading creative performance, authentic, empowering, and entrepreneurial leadership demonstrated the strongest relationships. For innovative performance, both transactional (contingent reward) and supportive leadership appear particularly relevant. The current study synthesizes an important, burgeoning, diverse body of research, and in doing so, generates nuanced evidence that can be used to guide theoretical advancements, improved research designs, and up-to-date policy recommendations regarding leading for creativity, and innovation.     

Age differences in neural activity related to mentalizing during person perception

ABSTRACT

Mentalizing, or thinking about others’ mental states, shapes social interactions. Older adults (OA) have reduced mentalizing capacities reflected by lower medial prefrontal cortex (mPFC) activation. The current study assessed if OA’ lower mPFC activation reflects less spontaneous mentalizing during person perception. Younger adults (YA) and OA viewed ingroup White and outgroup Black and Asian faces and completed a mentalizing task during fMRI. Afterward, they completed a task in which they inferred mental states from faces. Using an mPFC region defined by the mentalizing task, OA had lower activity than YA during person perception. OA’ mPFC activity toward faces positively related to their mentalizing outside the scanner. The extent of OA’ lower mPFC activation during person perception may depend on their actual detection of mental states in faces. Further, YA’, but not OA’, mPFC activity distinguished between outgroups. OA’ lower mentalizing-related mPFC activity may reduce their ability to individuate outgroup members.

Temporal integration of spatially filtered visual images.

Factors which govern the temporal integration of spatial information were examined in a group of five experiments. A series of high-pass and low-pass spatially filtered versions of a visual scene were generated. Observers' ratings of these filtered versions of the scene for perceived image quality indicated that quality was determined both by the bandwidth of spatial information and the presence of high-spatial-frequency edge information. When sequences of three different versions of the scene were presented over an interval of 120 ms the perceived quality of the resulting composite image was determined both from the ratings of the individual components of that sequence and from the order in which these components were presented. When the order of spatial information in a sequence moved from coarse to fine detail the perceived quality of the composite image was significantly better than when the order moved from fine to coarse. This evidence of a coarse-to-fine bias in pattern integration was further investigated with a detection paradigm. The pattern of errors once again indicated that temporal integration of spatial information was superior when a coarse-to-fine mode of information delivery was employed. Taken together the data indicate that the pattern-integration mechanism has an inherent order bias and does not accumulate spatial information so efficiently when the 'natural' coarse-to-fine order is violated.     

Remember Bonaventure? (Onto)Theology and Ecstasy

Taking note of the tendency of some authors in contemporary philosophy and theology to assume that medieval Christian theology as such is ontotheology, the essay first reviews several current uses of ontotheology and its correlates. It then tests these uses against the theology of Bonaventure, who is often included but often unexamined in these current critiques of medieval ontotheology. It concludes that Bonaventure is not ontotheological, but perhaps surprisingly, he offers a critique of his fellow scholastics that has striking resonance with Heideggerian and other postmodern worries about the uses of ontology in particular and scholastic reasoning more generally.
