Human Interaction With Robotic Systems: Performance And Workload Evaluations

We first tested the effect of differing tactile informational forms (i.e. directional cues vs. static cues vs. dynamic cues) on objective performance and perceived workload in a collaborative human–robot task. A second experiment evaluated the influence of task load and informational message type (i.e. single words vs. grouped phrases) on that same collaborative task. In both experiments, the relationship of personal characteristics (attentional control and spatial ability) to performance and workload was also measured. In addition to objective performance and self-report of cognitive load, we evaluated different physiological responses in each experiment. Results showed a performance–workload association for directional cues, message type and task load. EEG measures however, proved generally insensitive to such task load manipulations. Where significant EEG effects were observed, right hemisphere amplitude differences predominated, although unexpectedly these latter relationships were negative. Although EEG measures were partially associated with performance, they appear to possess limited utility as measures of workload in association with tactile displays. Practitioner Summary: As practitioners look to take advantage of innovative tactile displays in complex operational realms like human–robotic interaction, associated performance effects are mediated by cognitive workload. Despite some patterns of association, reliable reflections of operator state can be difficult to discern and employ as the number, complexity and sophistication of these respective measures themselves increase

Nationalism, Patriotism And Multinational Decision-Making Competence: Evidence From A Situation Judgment Test

Multiple factors may influence Warfighters’ ability to team effectively with personnel from other nations in joint military operations. The present study (N = 696) used a situation judgement test (SJT) to assess multinational decision-making competence. We hypothesized that both social identity and general decision-making competencies would be associated with SJT performance. Performance was associated with lower nationalism, and with decision-making competencies including application of decision rules and knowledge of social norms. Multivariate analyses suggested social identity and decision-making competence predicted performance independently, although nationalism and competence were negatively associated. These findings suggest that training strategies for Warfighters might identify the individual’s strengths and weaknesses, and tailor explicit instruction and virtual learning scenarios accordingly

Awe

If experiences of profound transformation have a core moment, that can be awe, an emotion able to maximize the possibility to change especially through its self-transcendent nature. Awe arises from stimuli so vast to prompt people to go beyond their current schema. Awe would drag people into a deep moment of uncertainty in which assimilation process fails, but accommodation has not successfully taken place yet. In this middle-suspended moment of extreme potential, everything might occur. This entry started with the current psychological definition of awe; then, it summarizes main researches in this field. Finally, I outlined the transformative nature of this phenomenon – as a self-transcendent emotion – and a new perspective to frame it in relation to a sense of possibility to change
