Social cognitive neuroscience and leadership

We provide an overview of how the emerging field of social cognitive neuroscience can be linked to leadership theory and practice. A number of challenges are addressed, including theory development, as well as technical, measurement and methodological issues. In addition, we review recent leadership research that involves neuroscience applications, as well as areas that are closely related to leadership, such as emotional regulation and ethical reasoning and decision-making. Consideration is also given to how neuroscience might inform leadership development processes. We conclude with a discussion of the institutional challenges in conducting leadership research that incorporates neuroscience, and we consider potential limitations of such applications.     

Social network and social capital in leadership and management research: A review of causal methods

This paper surveys the methods underlying the burgeoning body of leadership and management research on social networks and social capital (SNSC). A social network is a social structure made up of nodes connected by a set of ties. Social capital, in turn, refers to the structure, content, and perception of one's social relationships in the network. This paper presents an in-depth survey of the methods of using SNSC in leadership and management research. I first review how network scholars determine network boundaries, choose sampling techniques, and collect network data. I follow with a comprehensive survey of the statistical tools and analytical strategies prevalent in SNSC research. I then investigate the methodological rigor of 110 SNSC empirical studies in leadership and other management fields. My results show that 8.1% (3/37) specified network boundaries, 43.2% (49/103) used surveys to collect network data, and 52.3% (58/110) implemented at least one reviewed method. A further assessment reveals that only 39.7% (23/58) of papers somewhat justified the appropriateness of using such methods. The frequency distribution of coding criteria was similar across journals and over time. This review also includes several future research directives for SNSC leadership and management researchers.     

Incorporating social networks into leadership development: A conceptual model and evaluation of research and practice

Multilevel and relational views of leadership are expanding the focus of leadership development beyond individuals' knowledge, skills, and abilities to include the networked patterns of social relationships linking members of dyads and larger collectives. In this review, we present a conceptual model explaining how three distinct approaches for network-enhancing leadership development can improve the leadership capacity of individuals and collectives. We then present a review of the leadership development literature and the results of a survey of 282 practitioners to assess the extent to which these approaches have been examined in research and implemented in practice. Our review revealed that leadership research and leadership development practice are outpacing leadership development research in terms of incorporating networks. We aim to spur future research by clarifying the targets, objectives, and underlying mechanisms of each network enhancing leadership development approach in our conceptual model. Further, we identify additional literature, not traditionally considered within the realm of leadership development that may help advance empirical examinations of these approaches.     

The female leadership advantage: An evaluation of the evidence

Journalists and authors of trade books increasingly assert a female advantage in leadership, whereby women are more likely than men to lead in a style that is effective under contemporary conditions. Contrasting our analysis of these claims with Vecchio's [Leadersh. Q. 13 (2002) 643] analysis, we show that women have some advantages in typical leadership style but suffer some disadvantages from prejudicial evaluations of their competence as leaders, especially in masculine organizational contexts. Nonetheless, more women are rising into leadership roles at all levels, including elite executive roles. We suggest reasons for this rise and argue that organizations can capture the symbols of progressive social change and modernity by appointments of women in key positions.     

The evaluation of two key leadership development program components: Leadership skills assessment and leadership mentoring

This study evaluated two key components in leadership development programs: a 360-degree assessment of leadership skills and leadership mentoring. The participants in this study include 303 individuals in a leadership development program and 41 leadership mentors. The methodology and underlying rationale for using the two methods selected to evaluate the program are described. The results illustrate the degree to which mentees open up when mentors focus more on coaching and less on compliance and when mentors initiate personal contact with the mentees more often. The results also indicate that self-reports and observer-reports are statistically significantly different from one another. Implications and limitations are discussed.     

The downside of transformational leadership when encouraging followers to network

Network scholars argue that one responsibility of leaders is to help their followers develop social capital. We suggest that one way leaders do this is by encouraging followers to engage in networking behavior. However, we argue that such encouragement is more effective when leaders are seen as less transformational, because followers are then less able to benefit from their leaders’ social capital. We support our arguments with a study of 142 followers and their leaders. Our findings show that followers engage in greater networking behaviors when encouraged by their leaders to do so, but this association is moderated by leaders’ transformational leadership style such that it is stronger as transformational leadership behaviors decrease. We thus introduce an unrecognized cost of leaders’ transformational leadership behaviors. Our findings contribute to research on networking behavior by investigating the role of transformational leadership style, and suggest avenues for research linking social capital and leadership.     

An evaluation of conceptual weaknesses in transformational and charismatic leadership theories

Theories of transformational and charismatic leadership provide important insights about the nature of effective leadership. However, most of the theories have conceptual weaknesses that reduce their capacity to explain effective leadership. The conceptual weaknesses are identified here and refinements are suggested. The issue of compatibility between transformational and charismatic leadership is also discussed. Finally, some methodological problems involving construct validation and theory testing are identified, and suggestions for future research are provided.     

Development and evaluation of cognitive and metacognitive measures for predicting leadership potential

This article describes the development of an on-line computer-based cognitive and metacognitive skill assessment battery (the MLE) designed for assessment and development of high-level executives. The reliability and validity of the skill measures were calculated on a sample of senior officers at the National Defense University, Industrial College of the Armed Forces. Significant criterion-related validity of the MLE assessment battery was obtained, which confirmed the hypothesis regarding the importance of these skills for solving problems involved in high-level executive leadership. The special importance of metacognitive processing and solution construction skills was confirmed.     

Leading public sector networks: An empirical examination of integrative leadership behaviors

The literature has often suggested that network leadership is different from leadership in hierarchical/single-agency structures. While this difference has been assumed, relatively little research has been conducted to determine whether such a distinction between network and hierarchical leadership actually exists. This study addresses this gap in the literature using data from 417 public sector leaders. We compared the leadership behaviors exhibited by a leader in their government agency with the behaviors exhibited by that same individual while leading his or her network. The leadership behaviors were classified into one of three categories common in the leadership literature. The results indicate that while the frequency of organization-oriented behaviors vary widely between the agency and network contexts, leaders in their networks focus more on people-oriented behaviors and less on task-oriented behaviors when compared to leading their agency.     

Emergence of shared leadership networks in teams: An adaptive process perspective

Adaptive leadership theory suggests that shared leadership networks grow in a complex manner. We propose that leadership decentralization (the dispersion of leadership), leadership density (the total amount of leadership), and situationally-aligned leadership (SAL: leadership transitions to those who fit situation requirements) are distinct aspects of a shared leadership network and should be examined together to capture the development of shared leadership process. Through a study of 450 participants in 90 teams, we find that each of these three aspects of shared leadership plays a different role during shared leadership network emergence. Specifically, transactive memory systems (TMS) contribute to decentralized leadership structures, which in turn precipitate more dense leadership networks. We also find that TMS contributes to the most situationally aligned team member engaging in leadership. Both leadership density and SAL predict team performance. We discuss the theoretical and practical implications of these results.     

Criticism and outstanding leadership: An evaluation of leader reactions and critical outcomes

Outstanding political leaders are frequently called upon to make high-stakes decisions. Because of the controversial and highly visible nature of these issues, they often face intense criticism. Leaders' responses to criticisms not only affect follower reactions, but also the successful resolution of the contested issue. The present study examines leader and follower reactions to different types of criticisms. A historiometric approach was used to examine biographies containing criticisms of 120 world leaders and to explore leader behaviors in response to criticisms. Specifically, leader response strategies and their success in terms of follower reactions and resolution of the criticism were examined. The results indicated that collaborative or confrontational leader response strategies proved most effective in terms of the leader's ability to continue forward with a particular agenda item and to gather support of those around him or her. Conversely, avoidant, diverting attention, and persuasive response strategies proved less effective.     

The ties that lead: A social network approach to leadership

This article investigates, for leadership research, the implications of new directions in social network theory that emphasize networks as both cognitive structures in the minds of organizational members and opportunity structures that facilitate and constrain action. We introduce the four core ideas at the heart of the network research program: the importance of relations, actors' embeddedness, the social utility of connections, and the structural patterning of social life. Then we present a theoretical model of how network cognitions in the minds of leaders affect three types of networks: the direct ties surrounding leaders, the pattern of direct and indirect ties within which leaders are embedded in the whole organization and the interorganizational linkages formed by leaders as representatives of organizations. We suggest that these patterns of ties can contribute to leader effectiveness.     

Applying multilevel confirmatory factor analysis techniques to the study of leadership

Statistical issues associated with multilevel data are becoming increasingly important to organizational researchers. This paper concentrates on the issue of assessing the factor structure of a construct at aggregate levels of analysis. Specifically, we describe a recently developed procedure for performing multilevel confirmatory factor analysis (MCFA) [Muthen, B.O. (1990). Mean and covariance structure analysis of hierarchical data. Paper presented at the Psychometric Society, Princeton, NJ; Muthen, B.O. (1994). Multilevel covariance structure analysis. Sociological Methods and Research, 22, 376–398], and provide an illustrative example of its application to leadership data reflecting both the organizational and societal level of analysis. Overall, the results of our illustrative analysis support the existence of a valid societal-level leadership construct, and show the potential of this multilevel confirmatory factor analysis procedure for leadership research and the field of I/O psychology in general.

Polynomial regression analysis and response surface methodology in leadership research

Congruence has served as an important research framework for many leadership research topics. Perhaps the most frequently used methodological/statistical approach for testing the congruence framework is polynomial regression analysis (PRA) with response surface methodology (RSM). As this approach was introduced to organizational sciences more than two decades ago, we can now identify the main issues with the use of this approach in leadership research. To systematically investigate these issues, we first review how PRA and RSM have been used in various leadership studies. We then review the levels-of-analysis and rater model assumptions prevalent in PRA in terms of multilevel techniques, choice of centering options, and issues of endogeneity. Finally, to better understand the inconsistencies and variabilities that exist in leadership research, we review the use of two main RSM features and summarize additional statistical techniques for assessment in this realm. Overall, we aim to promote the rigorousness of this methodology within the study of congruence in leadership research by enhancing its capability in theory testing and building.     

Women's political leadership participation around the world: An institutional analysis

Understanding institutional systems is critical for the advancement of women's participation in leadership in varying contexts. A unique and global analysis of the contextual factors that affect women in political leadership, this paper extends prior research in the field. This is a cross-country study where we ask, “How are societal-level institutional forces related to women's participation in political leadership?” We collected data from 8 secondary sources on 181 countries and conducted linear regression analyses with six institutional influences: the business environment, societal development, the economic environment, physical and technological infrastructure, political freedom, and culture. Results indicate that to increase the political leadership participation of women, we need to evaluate the following: customs and trade regulations, graft, the gender gap in political empowerment, public spending on education, the economic viability of the country, access to power and the internet, political freedom, and cultural variables like performance orientation, collectivism, and power distance.
