Age and management team performance.

180 male managers participated as age-homogeneous 4-person teams in a validated all-day decision-making simulation. 15 teams consisted of 28–35 yr old participants (young), 15 teams were in the 45–55 yrs age range (middle-aged), and 15 teams consisted of 65–75 yr old (older) persons. More than 40 objective performance measures (loading on 12–25 factors) were calculated on the basis of team decision making, planning, and other indicators. Performance by young and middle-aged teams was generally similar. Older teams made fewer decisions and were less strategic and less responsive to incoming information. Their overview of the task was less broad; action diversity and information search was reduced. However, older teams used opportunities and handled a simulated emergency as effectively as their younger and middle-aged counterparts. Alternative explanations for the obtained differences are presented. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
