Task complexity as a moderator of goal effects: A meta-analysis

Abstract

Much evidence exists that supports the use of goal setting as a motivational technique for enhancing task performance; however, little attention has been given to the role of task characteristics as potential moderating conditions of goal effects. Meta-analysis procedures were used to assess the moderator effects of task complexity for goal-setting studies conducted from 1966 to 1985 ( n = 125). The reliability of the task complexity ratings was .92. Three sets of analyses were conducted: for goal-difficulty results (hard vs. easy), for goal specificity–difficulty (specific difficult goals vs. do-best or no goal), and for all studies collapsed across goal difficulty and goal specificity–difficulty. It was generally found that goal-setting effects were strongest for easy tasks (reaction time, brainstorming), d = .76, and weakest for more complex tasks (business game simulations, scientific and engineering work, faculty research productivity), d = .42. Implications for future research on goal setting and the validity of generalizing results are discussed. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
