A comparison of physical activity in men and women with cardiac disease: do gender roles complicate recovery?

Fifty-four male and twenty-six female married cardiac patients were studied for five months post-hospital discharge. Participants completed activity diaries for three days at 5, 10, 15, and 20 weeks. Reported activities were converted to METs. Patients increased activity across the five-month study period. Patients also tended to engage in higher levels of activity in the morning hours. Men and women did not differ in average total METs expended. Comparisons for specific activities indicated that women consistently expended more energy on domestic responsibilities, such as cleaning and laundry. Men engaged more in repairs, yardwork and carrying, but these activities were performed sporadically and involved low METs requirements. The concentrated domestic activity assumed by women early in recovery may pose a risk of complications.

How do female and male cardiac patients and their spouses share responsibilities after discharge from the hospital?

This study explored sex differences in household and employment responsibilities among cardiac patients (N = 63; 46 men) and spouses during the 5 months following discharge from the hospital. Results showed that both patients and partners maintained traditional sex-typed activities. As patients or spouses, women tended to assume greater responsibility for domestic tasks such as laundry, cleaning, and cooking than their husbands. Men as patients or spouses tended to assume greater responsibility for household repair and maintenance tasks. Husbands also worked more for pay outside the home than did wives, except in couples where the male patient was high risk. Correlations for male patients indicated that reports of more cardiac symptoms were associated with assuming fewer responsibilities. In contrast, among women, the correlations between symptoms and activities were more complex and suggested that female patients might not be heeding signs of overexertion.

Likelihood judgment based on previously observed outcomes: the alternative-outcomes effect in a learning paradigm.

Previous research has demonstrated that intuitive perceptions of certainty regarding a focal outcome are sensitive to variations in how evidence supporting nonfocal alternatives is distributed, even when such variations have no bearing on objective probability. We investigated this alternative-outcomes effect in a learning paradigm in which participants made likelihood judgments on the basis of their memory for past observations of relevant outcomes. In Experiment 1, a manipulation of evidence (observed frequencies) across alternative outcomes influenced not only intuitive certainty estimates about a focal outcome but also numeric subjective probabilities. Experiment 2 ruled out the possibility that these effects were attributable to the influence of information loss on frequency estimations. The findings were consistent with the heuristic comparison account, which suggests that the judged likelihood of a focal outcome will be disproportionately influenced by the strength (frequency) of the strongest alternative outcome.
