Previous studies have examined either coping strategies or defense mechanisms; however, few have considered both. This research examined age differences in the type of defense mechanisms and coping strategies that people employ. In addition, gender differences, personality and environmental variables were taken into account. The three age groups used in this study included: 17-23 year olds, 40-...

INTRODUCTION  The resonant frequency is the probe frequency in which susceptance is 0 due to the neutralization of the forces of mass and stiffness components that control the middle ear. This frequency can be evaluated by multifrequency tympanometry, and the normality value for adults ranges 800-1,200 Hz. Studies about resonant frequency in children are scarce. AIM  Identify the variation of...
