Yeah.
Adding to this, emotion informs rationality. There is no purely rational reason to do anything. It wouldn't be rational to avoid death if we didn't fear it. It wouldn't be rational to eat food if we didn't desire it. Rationality requires feelings like for example desire, disgust, fear, anger, hope to motivate performing any action what so ever.
It's essentially the is-ought problem, without feelings, rationality alone only presents us with things that are, not what ought to be.
If Spock was purely rational and void of any emotion, he'd be catatonic. He wouldn't eat, he wouldn't sleep, he couldn't do his job. If someone pushed him, he'd fall over and then he'd lay there with a blank stare.
Reason allows us to act in more complex ways than knee-jerk reactions, allows us to predict outcomes that may override desires and fears, to prioritize among the perceived goods, to figure that every promise may not hold up.
This is probably what people mean when they speak of acting rationally, applying rationality to the outcome of desires and fears are they really good/bad for us, or are they deceiving us into acting against our interest. This is basically Socratic ethics.
