SUMMARY:Auditory Distractions and Pilot Monitoring Performance Using MATB-
 II
DESCRIPTION:Anna Crofton and Mustapha Mouloua (University of Central Flori
 da)\n\nPilot attention and auditory distraction are central concerns in av
 iation safety, yet the specific effect of instructional framing on system 
 monitoring performance remains poorly understood. The present study examin
 ed whether framing either the communication task or the system monitoring 
 task as operationally critical would shift attentional allocation and infl
 uence perceived workload in a simulated multi-task environment. Drawing on
  Multiple Resource Theory (Wickens et al., 2003), it was hypothesized that
  critical framing would measurably redirect cognitive resources toward the
  designated priority task. A sample of 116 undergraduate participants comp
 leted three 30-minute trials on the Multi-Attribute Task Battery II (MATB-
 II) under one of three between-subjects conditions: Control, CommCritical,
  or SysMonCritical. Neither hypothesis was supported; a linear mixed-effec
 ts model revealed no significant effect of instructional framing on system
  monitoring performance. A robust practice effect emerged across all condi
 tions, suggesting task familiarity was the primary driver of performance g
 ains. A significant main effect of condition on perceived workload was obs
 erved, with the SysMonCritical group reporting lower workload than both ot
 her groups, though pairwise comparisons remained marginal. These findings 
 suggest that single-sentence instructional manipulations are insufficient 
 to redirect attentional allocation in complex multi-task environments, whi
 le indicating that framing may independently influence perceived demand.\n
