The present research explored the intrinsic relationship of self-reported depressive symptoms and cognitive distortions as proposed by Beck and others. A devised scale of cognitive distortions was correlated with scores on the Beck Depression Inventory for 67 college volunteers. A significant value of 0.59 was found, supporting our hypothesis. There were no sex differences on either scale.

Alpha wave production has been related to affective and physiological arousal states since Berger's (1929) initial research. More recently, the possibility of subjects' control of alpha production has been investigated via the innovation of biofeedback procedures. Research conducted by Kamiya in the 1960s and others led to the early conclusion that alpha-wave production could be controlled and that such control could facilitate enhancement of a person's state of physical and psychological well-being. Subsequent research data have questioned these conclusions. The present study focused upon alpha-wave production with or without a procedure for relaxation called "open-focus training." Twenty subjects were divided into four equal groups and seen for three 20-min. sessions. Results suggested a deterioration of alpha production with all groups combined, no significant differences between the biofeedback and no biofeedback control groups (without "open-focus training"), and greater decrease in alpha production during each session in the "open-focus" groups (with or without biofeedback). These unusual results and their implications are discussed.
