The Effort-Performance Gap in Motivational Communication: An Experimental Test of Linguistic Framing on Engagement and Task Accuracy

Background: While motivational communication is hailed as a key to performance, its direct effect on task accuracy remains unclear. This study investigates the differential effects of mastery-oriented and autonomy-supportive communication frames on employee engagement and task performance, testing for the presence of an "effort-performance gap." Methods: In a between-subjects online experiment, 198 working professionals were randomly assigned to one of three conditions: mastery-oriented frame, autonomy-supportive frame, or neutral control frame. Participants completed a cognitive task (Remote Associates Problems) while we measured self-reported motivation, behavioral engagement (time-on-task, persistence), and objective performance (accuracy). Results: The mastery-oriented frame significantly increased all measures of engagement (self-report, time-on-task, persistence) compared to control. The autonomy-supportive frame significantly increased time-on-task but not self-reported motivation. Critically, despite these strong effects on engagement, neither motivational frame produced a statistically significant improvement in task accuracy compared to the control condition. Conclusion: The findings reveal a clear effort-performance gap: strategically framed language effectively boosts motivation and effort but does not automatically translate into higher quality performance on a cognitive task. This underscores the need for managers to pair motivational communication with investments in employee skill and task design to reliably convert increased effort into improved outcomes.
