Attitude Signal
When signaling standard attitude, a high card is encouraging and a low card is discouraging. Attitude is normally signaled when following suit to partner's led suit and when discarding on either partner's or declarer's led suit.
For example, if partner leads the Ace of spades, you might signal with the nine if you held the King (requesting partner to continue the suit), or with the three if you held nothing but small cards in spades (notifying partner that a switch to another suit is likely best).
Of course, you can only signal with the cards you hold. Signaling low is easy for you, but if your lowest card is the eight, partner might have difficulty "reading" it as low. When you are signaling high, play the highest card you can afford. Having easily-readable cards to signal with is part of the luck of the deal.
Suppose declarer is drawing trumps and you are out on the third round. Your discard should be an attitude signal for partner. If you play a high-spot diamond, for example, you ask partner to lead diamonds if she should gain the lead. Normally, you would have an honor or honors in diamonds in this case. If you play a low diamond, you ask partner to not lead diamonds if she should gain the lead. Partner will usually be able to figure out which of the other suits you do like (if any).
If declarer plays yet another round of trump, you may be able to play yet another diamond. This will make it unambiguous to partner whether you are encouraging diamonds (by playing high-low) or discouraging diamonds (by playing low-high).

Famous quotes containing the words attitude and/or signal:
“The attitude is we live and let live. This is actually an amazing change in values in a rather short time and it’s an example of freedom from religion.”
—Tom Wolfe (b. 1931)
“Certainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.”
—Ursula K. Le Guin (b. 1929)
