Cue utilisation predicts control room operators' performance in a sustained visual search task

Cue utilisation is partially related to performance on an urban operations course but not experience

INTRODUCTION

Decision making in use of force relies on accurate cue identification to inform appropriate response. This research was designed to test the relationship between cue utilisation and performance prior to, and following participation in an urban operations course (UOC).

METHODS

A total of 37 participants were assessed on cue utilisation measures, course outcome and between group changes following course participation.

RESULTS

A significant main effect was evident for Cue utilisation and administration, (p = 0.005), but not training group, (p = 0.54), nor between groups and point of administration, (p = 0.410). No main effect was evident between groups and training outcome, (p = 0.11). However, there was a main effect for point of administration, (p = 0.02) and training outcome and point of administration (p = 0.02).

CONCLUSION

Although cue utilisation is an essential component of perception-action tasks, cues may be more specific to the relevant training environment with limited transfer to the operational context.

Cue utilization and pool lifeguarding

INTRODUCTION

Amongst pool lifeguards, the capacity to identify drowning swimmers quickly and accurately depends on the interpretation of critical cues. However, assessing the capacity for cue utilization amongst lifeguards at present is costly, time-consuming, and largely subjective. The aim of this study was to test the relationship between cue utilization and the detection of drowning swimmers in a series of virtual public swimming pool scenarios.

METHOD

Eighty-seven participants with or without lifeguarding experience engaged in three virtual scenarios, two of which were target scenarios where drowning events occurred within a 13 minute or 23 minute period of watch. Cue utilization was assessed using the pool lifeguarding edition of the EXPERTise 2.0 software following which 23 participants were classified with higher cue utilization, while the remaining participants were classified with lower cue utilization.

RESULTS

The results revealed that participants with higher cue utilization were more likely to have acquired experience as a lifeguard, were more likely to detect the drowning swimmer within a three minute period, and, in the case of the 13 minute scenario, recorded a greater dwell time on the drowning victim prior to the drowning event.

CONCLUSION

The results suggest that cue utilization is associated with drowning detection performance in a simulated environment and could be employed as a basis for assessments of performance amongst lifeguards in the future.

PRACTICAL IMPLICATIONS

Measures of cue utilization are associated with the timely detection of drowning victims in virtual pool lifeguarding scenarios. Employers and trainers of lifeguards can potentially augment existing lifeguarding assessment programs to quickly and cost-effectively identify the capabilities of lifeguards. This is especially useful for new lifeguards or where pool lifeguarding is a seasonal activity that might be associated with skill decay.

Cross-task cue utilisation and situational awareness in learning to manage a simulated rail control task

Cue utilisation and situational awareness share similar properties since both constructs are dependent upon the application of feature-event associations in memory. The aim of this study was to investigate the extent to which cue utilisation and situational awareness contribute to learning a simplified, simulated rail control task incorporating an implicit pattern of train movements. Fifty-five undergraduate students completed an assessment of cue utilisation prior to completing the rail control task during periods of lower and higher task demands. Situational awareness was assessed using Situation Awareness Global Assessment Technique (SAGAT) queries. The results indicated that, while both cue utilisation and situational awareness were related to the detection of the implicit pattern of train movements, they contributed separately to performance on the simulated rail control task. The outcomes suggest that cue utilisation and situational awareness may be separate constructs, where cue utilisation constitutes a capacity variable that is associated with changes in response to task demand and situational awareness constitutes an outcome variable that emerges through task exposure.
