It can get a little imbalanced sometimes. Children are often over-praised to the point that they feel that they deserve praise no matter what they do. Definitely not psychologically healthy.
Then the converse can be true when certain adults (and many aspies) find that no matter what they do it's never 'right' or 'good enough'. (This is actually a form of bullying--see below).
What is bullying?
* constant nit-picking, fault-finding and criticism of a trivial nature - the triviality, regularity and frequency betray bullying; often there is a grain of truth (but only a grain) in the criticism to fool you into believing the criticism has validity, which it does not; often, the criticism is based on distortion, misrepresentation or fabrication
* simultaneous with the criticism, a constant refusal to acknowledge you and your contributions and achievements or to recognise your existence and value
* constant attempts to undermine you and your position, status, worth, value and potential
* when you are in a group, being singled out and treated differently; for instance, everyone else can get away with murder but the moment you put a foot wrong - however trivial - action is taken against you
* being belittled, demeaned and patronised, especially in front of others
* having unrealistic goals set, which change as you approach them
* finding that everything you say and do is twisted, distorted and misrepresented
