“…While previous studies have suggested that life histories (Avolio and Gibbons, 1998;Bass, 1998), parental influence (Popper and Mayseless, 2003), and personality factors (Johnsen et al, 2006) could explain individual differences in transformational leadership skills, the present findings provide empirical evidence to suggest that even relatively time limited, but carefully designed and well timed training interventions could promote the development of certain problem-solving and systems skills (Bass and Avolio, 1994;Streufert et al, 1988). It is interesting to note that similar forms of intensive training experiences based on action learning principles (Pedler, 1997), also have been found to influence a number of outcome variables on the team level, such as leader preferences, status hierarchies, and group polarization Eid, 1990, 1994), as well as team cohesion (Bartone et al, 2002) in Navy officer cadets.…”
