What separates two equally talented performers under pressure?

Often, it’s not skill. It’s not preparation. It’s belief.

In this episode of Human Performance 360, Dr. Parsa Peykar sits down with Deborah Feltz, distinguished professor at Michigan State University and one of the foremost authorities on self-efficacy in sport and exercise psychology.

Building on the foundational work of Albert Bandura, Dr. Feltz has spent decades researching how belief influences performance — from individual athletes to entire teams.

Together, we explore:

What self-efficacy truly is — and how it differs from confidence or self-esteem

The four scientifically validated sources of belief

How athletes can use failure to strengthen — not weaken — efficacy

The role of physiological interpretation (nerves, adrenaline, fatigue) in performance

Coaching efficacy — and how a leader’s belief shapes team outcomes

The difference between calibrated confidence and dangerous over-belief

How self-efficacy applies beyond sport — into leadership, entrepreneurship, and life

This episode moves beyond motivational language and into evidence-based performance science.

You’ll learn why self-efficacy predicts:

Effort

Persistence

Emotional regulation

Resilience under pressure

And ultimately, results

Whether you’re an athlete, coach, executive, student, or creator — this conversation will challenge you to examine a powerful question:

Where is your belief coming from — and is it strong enough to support your next level?

Think of one area in your life where you hesitate — not because you lack skill, but because you lack belief.

What would change if you acted as if you could?
