What are three functions of attention?
Attention helps prioritize relevant information, maintain focus, and coordinate actions.
What can happen when attentional demands exceed capacity?
When demands exceed available attention, people may miss information, respond more slowly, or make more errors.
When are two tasks especially likely to interfere?
Two demanding tasks that rely on similar perceptual or response processes are more likely to interfere with each other.
What is a trade-off of selective attention?
Focusing on one task prioritizes relevant information, but makes other events less likely to be noticed. What gets filtered depends partly on task demands and goals.
What often underlies apparent multitasking?
What looks like multitasking often involves rapidly switching between tasks rather than processing both fully in parallel.
How can switching between tasks affect performance?
Switching takes time and can disrupt the mental set needed to resume a task.
Which processing demands make task interference more likely?
Interference is more likely when tasks compete for the same limited processing stages, especially decision-making or response selection.
How can practice affect the attention a task requires?
Practice can make an action faster and require less deliberate attention, making it easier to combine with another activity.
Why does automaticity not eliminate attentional demands?
Automaticity is a matter of degree, not a guarantee. New conditions, interruptions, fatigue, or unexpected events can make a familiar task demand more attention.
What is sustained attention?
Sustained attention is maintaining focus over time, especially during repetitive tasks or when signals are infrequent.
What is the vigilance decrement?
The vigilance decrement is a decline in monitoring performance over time, such as slower responses or missed targets.
What does an attentional lapse not necessarily indicate?
A lapse does not necessarily show a lack of skill or motivation; performance also reflects task demands and alertness.
