In many emerging civilian and military operations, human operators are increasingly being tasked to supervise multiple robotic uninhabited vehicles (UVs) with the support of automation. As 100% automation reliability cannot be assured, it is important to understand the effects of automation imperfection on performance. In addition, adaptive aiding may help counter any adverse effects of static (fixed) automation. Using a high-fidelity multi-UV simulation involving both air and ground vehicles, two experiments examined the effects of automation reliability and adaptive automation on human-system performance with different levels of task load. In Experiment 1, participants performed a reconnaissance mission while assisted with an automatic target recognition (ATR) system whose reliability was low, medium, or high. Overall human-robot team performance was higher than with either human or ATR performance alone. In Experiment 2, participants performed a similar reconnaissance mission with no ATR, static automation, or with adaptive automation keyed to task load. Participant trust and self-confidence were higher and workload was lower for adaptive automation compared with the other conditions. The results show that human-robot teams can benefit from imperfect static automation even in high task load conditions and that adaptive automation can provide additional benefits in trust and workload.

Many current and emerging systems require human operators to supervise multiple uninhabited vehicles (UVs) with the support of automation. Automation is not 100% reliable; ergo it is important to understand the effects of automation imperfection on performance. This study investigated the effects of automation reliability on system performance with multiple UVs under different levels of task load. Twelve participants completed 12 “missions” supervising 3 (low load) or 6 (high load) UVs. Participants used one UV to conduct Reconnaissance, Surveillance and Target Acquisition. They were assisted with an automatic target recognition (ATR) system whose reliability was low, medium, or high. Overall system performance was higher than user or ATR performance alone. The gain in system performance with the ATR was particularly effective with medium and high automation reliability. Thus, human-robot teams can benefit from imperfect automation even under high workload conditions.

Sheridan's “Levels of Automation” were explored in an experiment on fault management of a continuous process control task which included situation adaptive automation. Levels of automation with more or less automation autonomy, and different levels of advice to the operator were compared, with automatic diagnosis whose reliability varied. The efficiency of process control and of fault management were explored under human control and automation in fault management, and aspects of the task in which human or automation were the more efficient defined. The results are related to earlier work on trust and self confidence in allocation of function by Lee, Moray, and Muir.

AbstractIt is well known that soccer sport has the potential for high levels of stress and anxiety and that these are linked to Cortisol (C) variations. To date, much research has been devoted to understanding how Oxytocin (OT) can affect anxiety in response to a challenge. The aim of this study was to investigate, in 56 young male soccer players, the psychophysiological stress response 96 and 24 h before one soccer match of a tournament, in order to establish whether athletes who won or lost, show different levels of C and OT or expressions of competitive state anxiety subcomponents. We found that winners had significantly lower Cognitive anxiety and higher Self-confidence scores than losers. Also, significant differences between winners and losers in C and OT concentrations were observed, with higher OT levels in who has won and higher C levels in who has lost. Our results showed interesting associations between OT, C, anxiety feelings, and the outcome of competition.

Automated Writing Evaluation (AWE) programs have emerged as the latest trend in EFL writing classes. AWE programs act as a supplementary to teacher feedback and offer automated suggestions and corrections to students' linguistic errors such as grammar, vocabulary, or mechanics. As there is a need for better recognition of different AWE brands utilized for different levels of students, this research sheds light on identifying six university students’ views of an AWE program, namely ProWritingAid (PWA). The six students are categorized as having high or low writing achievement. This descriptive study delineates the students’ perceptions qualitatively. A semi-structured interview was used to collect the data. The findings suggest the students’ positive views of PWA because it could make class time more effective; it had useful feedback on grammar, vocabulary choices, and mechanics; and it built students‘ self-confidence over their compositions. In addition, for different reasons, the students engaged differently with PWA to enhance their drafts, e.g. using PWA only for the first drafts or for the first and final drafts. Finally, despite of the students’ constructive views on PWA, there was a risk that students only engaged superficially with the program by hitting the correction directly.

Abstract Aim: The aim of this study was to identify factors that promote and impede other-sex (OS) friendships in adolescent girls. Methods: A qualitative study conducted with 20 adolescent girls recruited in public places in Tehran, Iran. Information was collected through semi-structured interviews and coded via the conventional qualitative content analysis approach. Results: Four factors were identified that appeared to promote entry into OS friendships. These factors include (a) a poor understanding of perceived risks, (b) weak religious beliefs, (c) processes of identity formation, and (d) low self-esteem. In addition, six factors appeared to impede entry into these friendships: (a) self-confidence, (b) prioritizing education, (c) maintaining particular entertainment preferences, (d) awareness of prior unpleasant experiences with boys, (e) having strong religious convictions, and (f) shaming from significant others. Conclusion: These findings provide unique insights into the factors that stem from different levels of social complexity, which affect participation in a fundamental form of human experience.

Multitasking requires human operators to handle the demands of multiple tasks through task switching at the same time and this ability is required in many jobs. Previous studies showed that different levels of working memory capacity (WMC) and task switching abilities can lead to differences on multitasking performance. With increased complexity of tasks, maintaining task performance is challenging. This study sought to find the relations of WMC, task switching, task difficulty, and multitasking performance. Multi-Attribute Task Battery II (MATB-II) was employed in this study as a platform to assess multitasking. Automated OSPAN and Trail Making Tasks (TMT) were used to assess WMC and the task switching ability, respectively. Results indicated that there were significant effects of these three parameters on multitasking performance. Other dimensions of multitasking performance will be addressed in future studies.
