Research findings suggest that switching between competing response sets can be resource demanding. The current study focused on concurrent health-relevant physiological effects of task switching by assessing cardiovascular response at varying levels of switch frequency. The participants performed a response-switching task at three different levels of response set switching frequency (low, medium and high) while measurements of blood pressure and heart rate were taken. One group was exposed to response-switching frequency conditions in the order low → medium → high, while the other group was exposed to the same task conditions in the reverse order (i.e. high → medium → low). The results showed that the participants in the low → medium → high switch frequency group recovered faster from initially heightened systolic blood pressure when compared with participants in the high → medium → low group. It is concluded that the results point to a physiological "carry over" effect associated with beginning a task at rapid response switching frequency levels, and suggest the importance of habituation to task demands as a means of offsetting potentially unhealthy levels of reactivity. Implications for modern work environments are discussed. 相似文献

Women have been active in the American Psychological Association (APA) almost from the beginning. In general, however, they did not attain high-level office, editorships, and significant committee posts at the same level as their male counterparts. During one 51-year period, for example, no women were elected to the APA presidency. Despite protests, little changed. Finally, in the 1970s, the climate in the APA shifted. The Committee on Women in Psychology was formed, as was the APA Division of the Psychology of Women. From then on, women's issues have remained an important concern of the association. 相似文献
