New research shows that leaders’ emotional expressions matter not only in content, but also in timing. Positive emotional expressions early in a team’s life are especially powerful, and when they are followed by stronger negative emotional expressions at the midpoint, individual performance can improve even more.
Why it matters:
Leaders shape performance not just through goals and feedback, but through the emotional signals they send. Organizations often train leaders on what emotions to express, but this research shows that when those emotions are expressed can matter just as much.
How we know:
The researchers used two longitudinal field studies. One drew on four waves of archival data from 9,968 consulting team members across 234 teams at a professional services firm over one year, using Linguistic Inquiry and Word Count (LIWC) to measure the emotional tone of leaders’ written feedback. The second followed 245 student-athletes and 86 coaches across 20 NCAA Division 1 varsity teams over a season, combining survey measures of leader emotional expressions with coach ratings and archival sports statistics.
What the researchers found:
- Positive emotional expressions from leaders during the early phase of a project team’s lifecycle had stronger positive effects on individual performance than the same positive expressions delivered at the midpoint.
- Early positive leader emotional expressions were more strongly related to end-of-year performance than midpoint positive expressions, and early negative emotional expressions were harmful to performance.
- The strongest performance gains appeared when early positive expressions were followed by above-average critical feedback at the midpoint. In that sequence, the early positivity seemed to make midpoint criticism feel more constructive and less disrespectful — but the effect held only when the criticism was warranted, not negativity for its own sake.
- Two mechanisms helped explain the pattern: early positive expressions built respect, and the combination of early positivity plus midpoint negativity also boosted status-related motivation to improve.
What this means:
- For HR and L&D teams: Training should cover not only which emotions leaders express, but also when they express them.
- For managers and team leads: Positive emotional expressions early in a team’s life appear to build a foundation of respect that makes later corrective feedback more effective.
Now what:
- Prioritize positive emotional expressions during the early phase of a team’s life.
- Build timing and sequencing into emotional intelligence training, so leaders understand that the order of their emotional expressions shapes how those messages are received later.
- Use midpoint feedback carefully. When it follows an early positive foundation, it is more likely to be experienced as constructive rather than discouraging.
