Multi-tasking and Dual-Task Management Flashcards

A pilot monitoring four instruments simultaneously notices two require immediate attention. Which cognitive strategy best describes optimal dual-task performance?

Answer: Alternate attention rapidly between both tasks using time-sharing

Time-sharing — rapidly alternating attention between concurrent tasks — is the core dual-task strategy. Neither full abandonment of one task nor true parallel processing is typically possible; skilled multi-taskers switch quickly between demands to minimise total error.

During a dual-task test a candidate must track a moving cursor AND respond to number sequences. Tracking accuracy drops 30% when the number task is introduced. This is BEST described as:

Answer: Interference effect

When a second task degrades performance on a primary task, this is the interference effect — competing demands reduce the cognitive resources available to each task.

In a multi-tasking aptitude test, which factor most strongly predicts a candidate's ability to maintain performance across simultaneous tasks?

Answer: Processing speed and working memory capacity

Processing speed and working memory are the primary predictors of dual-task performance. Working memory holds active information while processing speed determines how quickly attention can be reallocated between tasks.

A candidate scores 95% on a tracking task alone but drops to 60% when a secondary arithmetic task is added. A second candidate scores 85% alone and 78% with arithmetic added. Which candidate demonstrates better multi-tasking aptitude for a pilot role?

Answer: Candidate 2, because the performance drop is smaller

The key metric in multi-tasking assessments is performance degradation under dual-task conditions. Candidate 2's drop of 7 percentage points versus 35 indicates far superior ability to maintain performance under cognitive load.

Which of the following is NOT an effective strategy for improving dual-task performance?

Answer: Mentally labelling each task to increase conscious awareness of both

Mental labelling adds cognitive overhead without reducing task demands. The other options are legitimate strategies: automaticity reduces resource consumption; simultaneous training builds dual-task-specific skills; reducing task difficulty frees capacity.

A FAST candidate must track a drifting crosshair while responding to auditory tones. Which approach minimises total error across both tasks?

Answer: Establish a rhythmic correction pattern for tracking, freeing attention for tones

Establishing an automatic, rhythmic correction reduces the cognitive load of tracking, freeing attentional resources for the auditory task. This is the optimal dual-task strategy as one sub-task becomes semi-automatic.
