Abstract
Male and female engineering students were studies under stress induced by a cognitive-conflict task and in a control condition spent in inactivity. The results showed that (a) in the control condition the sexes did not differ in adrenaline, noradrenaline or cortisol excretion, whereas heart rate was significantly higher in the females; (b) adrenaline excretion and heart rate increased significantly in both sexes during stress: (c) the rise in adrenaline excretion was more pronounced in the males, whereas the rise in heart rate was significantly greater in the females; (d) cortisol excretion increased significantly during stress in the male group only; and (e) self-estimates of effort and performance were consistently higher and increased more over time in the males than in the females, but these sex differences on the subjective level were not reflected in actual performance. The interaction of biological and social factors in the development of sex differences in stress reactions is discussed.
