Mental fatigue influence on effort-related cardiovascular response: difficulty effects and extension across cognitive performance domains 总被引:2,自引:0,他引:2

Two experiments investigated cardiovascular effects of mental fatigue as a function of (1) the difficulty of the cognitive
challenge with which participants were confronted, and (2) the relevance of that challenge to the activity that instigated
the fatigue. In the first, participants performed an easy (fatigue low) or difficult (fatigue high) counting task and then
were presented an arithmetic challenge (task B relevance high) or a scanning challenge (task B relevance low) with instructions
that they would avoid a noise if they attained a modest performance standard. Analysis of blood pressure responses assessed
during the work periods revealed fatigue main effects, reflecting stronger responses for High Fatigue participants, regardless
of the character of the second task. In the second, the procedure was the same except that it included a high performance
standard and provided the chance to win a prize. Analysis of the pressure data revealed fatigue x work period interactions,
reflecting relatively stronger responses among High Fatigue participants in work period 1, but relatively weaker responses
among these participants in work period 2. Results confirm previous findings and support an analysis of fatigue influence
on effort and associated cardiovascular responses. They also argue against the idea that mental fatigue influence may be confined
to relevant cognitive performance realms.

The current study examined the connections among religious doubt, mental health, and aging in a nationwide sample of individuals
18 years and older (N = 1629). Findings indicate that that religious doubt emerging from the recognition of suffering and evil in the world has
a deleterious impact on mental health. Results also show that as people grow older, religious doubts continue to be associated
with psychopathology, but the magnitude of this association becomes weaker across age categories. In other words, the impact
of doubt on mental distress declines as one ages. These effects were found across various measures of mental distress, including
depression, general anxiety, interpersonal sensitivity, paranoia, hostility, and obsessive-compulsive symptoms. Findings are
explored within the context of psychosocial development and the experiential trajectory of religious maturity. 相似文献

Do disparate dimensions of magnitude share an underlying mental representation? Two recent papers offer suggestive evidence that participants' discrimination thresholds are identical across domains. Brannon, Lutz and Cordes showed that six-month-old infants' area discriminations match their number discriminations. VanMarle and Wynn demonstrated the same pattern for six-month-olds' discrimination of temporal duration. These parallels across infants' responses to number, area and time raise questions about the fundamental nature of quantity processing. 相似文献

This study assesses the health-related effects of trust-based prayer expectancies, which reflect the belief that God answers prayers at the right time and in the best way. The following relationships are evaluated in our conceptual model: (1) older Mexican Americans who attend worship services more often tend to develop a closer relationship with God; (2) people who feel close to God will be more likely to develop trust-based prayer expectancies; (3) people who endorse trust-based prayer expectancies will have greater feelings of self-esteem; and (4) higher self-esteem is associated with better self-rated health. The data support each of these relationships. 相似文献

Organizational empowerment is a multi-faceted concept that involves processes occurring both within and between organizations that facilitate achievement of their goals. This paper takes a closer look at three interorganizational processes that lead to empowered organizations: building alliances, getting the word out, and capturing others’ attention. These processes are located within the broader nomological network of empowerment and organizational empowerment, and are linked to particular patterns of interorganizational relationships that facilitate organizations’ ability to engage in them. A new network-based measure, γ-centrality, is introduced to capture the particular network structure associated with each process to be assessed. It is demonstrated first in a hypothetical organizational network, then applied to take a closer look at organizational empowerment in the context of a coordinating council composed of human service agencies. The paper concludes with a discussion of the implications of relationships between these processes, and the potential for unintended consequences in the empowerment of organizations. 相似文献
