Leadership in applied psychology: Three waves of theory and research.

Although in the early years of the Journal leadership research was rare and focused primarily on traits differentiating leaders from nonleaders, subsequent to World War II the research area developed in 3 major waves of conceptual, empirical, and methodological advances: (a) behavioral and attitude research; (b) behavioral, social-cognitive, and contingency research; and (c) transformational, social exchange, team, and gender-related research. Our review of this work shows dramatic increases in sophistication from early research focusing on personnel issues associated with World War I to contemporary multilevel models and meta-analyses on teams, shared leadership, leader-member exchange, gender, ethical, abusive, charismatic, and transformational leadership. Yet, many of the themes that characterize contemporary leadership research were also present in earlier research. (PsycINFO Database Record

Joint influences of individual and work unit abusive supervision on ethical intentions and behaviors: a moderated mediation model.

We develop and test a model based on social cognitive theory (Bandura, 1991) that links abusive supervision to followers' ethical intentions and behaviors. Results from a sample of 2,572 military members show that abusive supervision was negatively related to followers' moral courage and their identification with the organization's core values. In addition, work unit contexts with varying degrees of abusive supervision, reflected by the average level of abusive supervision reported by unit members, moderated relationships between the level of abusive supervision personally experienced by individuals and both their moral courage and their identification with organizational values. Moral courage and identification with organizational values accounted for the relationship between abusive supervision and followers' ethical intentions and unethical behaviors. These findings suggest that abusive supervision may undermine moral agency and that being personally abused is not required for abusive supervision to negatively influence ethical outcomes.

Implicit effects of justice on self-identity.

The authors provide one of the first tests of whether justice has effects at implicit or subconscious levels. By manipulating justice in a laboratory experiment, they found that the activation of interdependent and individual self-identities were higher when people experienced fairness and unfairness, respectively. Although these effects occurred at both implicit and explicit levels, they were stronger in the former case. These identity-based effects proved to be important because they mediated the effects of justice on trust and on cooperative and counterproductive behaviors. Implications of these findings for theory and practice are discussed.

Self-regulation at work.

Self-regulation at work is conceived in terms of within-person processes that occur over time. These processes are proposed to occur within a hierarchical framework of negative feedback systems that operate at different levels of abstraction and with different time cycles. Negative feedback systems respond to discrepancies in a manner that reduces deviations from standards (i.e., goals). This is in contrast to positive feedback systems in which discrepancies are created, which can lead to instability. We organize our discussion around four hierarchical levels-self, achievement task, lower-level task action, and knowledge/working memory. We theorize that these levels are loosely connected by multiple constraints and that both automatic and more conscious processes are essential to self-regulation. Within- and cross-level affective and cognitive processes interact within this system to motivate goal-related behaviors while also accessing needed knowledge and protecting current intentions from interference. Complications common in the work setting (as well as other complex, real-life settings) such as the simultaneous pursuit of multiple goals, the importance of knowledge access and expertise, and team and multiperson processes are also discussed. Finally, we highlight the usefulness of newer research methodologies and data-analytic techniques for examining such hierarchical, dynamic, within-person processes.

The impact of previous leaders on the evaluation of new leaders: an alternative to prototype matching.

In 2 studies, this research demonstrated the existence of leader transference, a cognitive process whereby mental representations of previous leaders are activated and used for evaluation when new, similar leaders are encountered. The 1st study demonstrated that exposure to a new leader who was similar to a past leader led to erroneous generalization of leader characteristics and associated underlying attributions. The 2nd study showed that expectations of just treatment and abuse were also subject to transfer from old to new, similar leaders, although positive and negative affective responses were not. Results suggested that individuals exposed to a leader who was not reminiscent of an old leader were more likely to use a general leader prototype to form leader expectations, whereas individuals exposed to a leader who was similar to an old leader activated a significant other mental representation for use in making judgments. These results have implications for individual- and relational-level processes as characterized by implicit leadership theory and leader-member exchange theory as well as macro theories of leader succession and organizational culture change.

Moving from cognition to behavior: What the research says.

In 1994, R. G. Lord and P. E. Levy proposed a variant of control theory that incorporated human information processing principles. The current article evaluates the empirical evidence for their propositions and updates the theory by considering contemporary research on information processing. Considerable support drawing from diverse literatures was found for propositions concerning the activation of goal-relevant information, the inhibition of goal-irrelevant information, and the consequences of goal completion. These effects were verified by meta-analytic analyses, which also supported the meaningfulness of such effects on the basis of their unstandardized magnitudes. The authors conclude by proposing new directions for this version of control theory by invoking recent theorizing on goal emergence and the importance of velocity and acceleration information for goal striving and by reviewing research in cognitive neuroscience.

An emotional mediation theory of differential age effects in episodic and semantic memories.

Although there is a large decrement in central episodic memory processes as adults age, there is no appreciable decrement in central semantic memory processes (Allen et al., Journal of Gerontology: Psychological Sciences, 57B, P173-P186, 2002; Allen et al., Experimental Aging Research, 28, 111-142, 2002; Mitchell, Journal of Experimental Psychology: Learning, Memory, and Cognition, 15, 31-49, 1989). The authors develop a theory of episodic memory's connections to cognitive, emotional, and motivational systems to explain these differential age effects. The theory is discussed within the context of the cognitive neuroscience research regarding limbic system connectivity in conjunction with Damasio's notion of somatic markers (Descartes' error: Emotion, reason, and the human brain, New York: Grosset/Putnam, 1994). The central hypothesis is that elements of limbic system circuitry, including portions of the medial temporal lobes and frontal cortex, are associated with both working and long-term episodic memory performance, and by extension, with the capacity to engage in emotion-guided, self-regulatory processes that depend heavily on episodic memory. In contrast, the semantic memory system may have less shared interface with episodic and affective networks (i.e., the limbic-related system), and therefore remain independent of neurocognitive changes impacting emotional states and episodic-type memory processes. Accordingly, this framework may account for the pattern of age-related declines in episodic relative to semantic memory, particularly if older adults experience less emotional activation, and therefore fewer somatic markers, than younger adults. An initial empirical examination of this emotional mediation theory is presented, using preexisting data that include indicators of age, chronic tendency to focus on negative emotional stimuli (neuroticism), and working memory performance.
