Emotions trump learning

I do agree with this thought to some degree, emotions can trump learning, if it is a positive experience and they understand the concepts being taught, are not shy, not afraid to speak up or ask for help, but on other hand i feel it can dissolve learning. If a student is struggling and doesn't get the help he/she needs then it can become a negative experience and he/she can shut down and not have a desire to continue to learn. This can be a fearful thing for a child, and can continue to spiral down until they have lost the desire to learn.
