Two-dimensional and M-mode echocardiographic findings in hypertensive pregnant women.

Two-dimensional and M-mode echocardiograms were obtained during the thirty-second week of gestation from 69 women classified as follows: group I, 22 normotensive primigravid women; group II, 16 primigravid women with pregnancy-induced hypertension; group III, 21 percent women with essential hypertension; and group IV, 10 normotensive nonpregnant control subjects. Systolic, diastolic, and mean arterial pressures were higher in groups II and III than in groups I and IV (p less than 0.001).

Effects of imagining speakers' voices on the retention of words presented visually.

Subjects were introduced to one male and one female voice by a tape recording with instructions to attend to characteristics of the voices. Then 18 pairs of words were presented visually on slides. The subject's task during each 10-sec interslide interval was to repeat silently the pair of words over and over again in the male voice, in the female voice, or in the subject's own voice.
