The sensitivity of tapping task to mental workload was investigated. Thirteen subjects were asked to produce 3 s intervals continuously while performing a time sharing task. The time sharing task was designed to manipulate a demand to allocate an attentional resource to one target and a demand to switch the target to which an attentional resource was mainly allocated. Results showed that produc...

The goal of the present experiment was to test the predictions of Central Bottleneck and Central Capacity Sharing models. According to the Central Bottleneck model, dual task interference, as observed in the PRP paradigm, is caused by an all-or-none bottleneck in information processing. The Central Capacity Sharing model postulates that dual task interference is caused by a capacity limited pro...

Research suggests that dual-task interference is caused by a central bottleneck (together with response grouping and impaired preparation). The emphasis placed on the 1st response in these experiments, however, may have discouraged the sharing of processing resources between tasks. In the present experiment, instructions placed equal emphasis on 2 choice reaction-time tasks in which stimuli wer...

Coordination and collaboration are naturally used by groups for carrying out activities and solving problems that require cooperation. However, getting a set of computer agents to do the same has been a problem primarily addressed by the AI community and recently by the database community as worlcfow and process management problems. Not surprisingly, the problem has been addressed at different ...

Task sharing, the involvement of non-specialists (non-physician clinicians or non-specialist physicians) in performing tasks originally reserved for surgeons and anesthesiologists, can be a potent strategy in bridging the vast human resource gap in surgery and anesthesia and bringing needed surgical care to the district level especially in low-resource countries. Although a common practice, the...

BACKGROUND Nowadays task sharing is a way to optimize utilization of human resources for health. This study was designed to assess the effect of task sharing, mutually between midwives and Family Health Workforces (FHWs), on the number of needed staff across the Iranian Health Posts. METHODS The workload and required number of midwives and FHWs in a Health Post were calculated and compared in...

Task-sharing has frequently been proposed as a strategy to overcome human resource shortages in order to scale up mental health care. Although evidence suggests this approach is effective, to date no review has been conducted to assess its acceptability and feasibility among service users and health care practitioners. This review summarises current findings and provides evidence-based recommen...
