| Abstract |
In a reply to our review entitled "Breathing Retraining: A Rational Placebo?," Ley has raised a number of comments (Clinical Psychology Review, 13, pp. 393-408). We do not agree with most of his remarks. Where his comments may be right, his opinion does not contradict our general conclusion. We maintain our conclusion that (a) there are no good reasons for assuming that the effects of breathing retraining are caused by decreasing the tendency to hyperventilate and (b) experimental evidence does not support the hyperventilation syndrome (HVS) model for panic.
