26 Questions

What is the typical outcome when individuals attempt to perform two or more tasks simultaneously?

A bottleneck where at least one task suffers

In experiments involving the simultaneous performance of two reaction time tasks, what is often observed regarding task performance?

The second task typically suffers

What term is commonly used to describe the phenomenon where individuals believe they are multitasking but are actually rapidly moving between tasks?

Task switching

Which of the following best describes the switch cost in multitasking scenarios?

Slower responses and less accurate performance after the switch

How does preparation and predictable switching affect the switch cost in multitasking scenarios?

It reduces the switch cost but does not eliminate it

Which brain regions are typically involved in task switching?

A variety of brain regions, including the prefrontal cortex, the parietal lobes, and the cerebellum

Which brain regions are predominantly activated during switch trials in task switching?

The extra striate cortex and the parietal cortex.

How can attention be directed, according to the provided information?

Attention can be both intentionally focused and unintentionally captured.

What statement is true regarding unintentional attention capture?

Unintentional attention capture can be both beneficial and problematic.

What is the consequence of being visually distracted while driving, as described in the information?

Less time spent on safety-relevant parts of the visual scene

Who is more susceptible to the negative effects of visual tunnelling while driving?

Novice drivers

What are the three primary types of distraction while driving mentioned in the content?

Visual, motor, and cognitive distractions.

How does attention to advertisements, designed to capture bottom-up attention, affect driving?

It diverts attention from processing vital driving information.

What is the visual tunnelling effect, as described in the provided information?

A situation where your gaze concentrates downward to a limited field.

Which of the following is a reason why the visual tunnelling effect is problematic when driving?

Hazards frequently occur in the periphery, outside the narrowed gaze.

In the study by Sturm et al. (1997), which attention functions were participants trained on?

Alertness, vigilance, selective attention, and divided attention

Which two attention functions showed the most improvement as a result of the specific training in the study by Sturm et al. (1997)?

Alertness and vigilance

What were the three attention-related advantages observed in gamers compared to non-gamers in the study by Green & Bavelier (2003)?

Greater memory capacity, faster reaction times, and improved visual acuity

What did the study by Green & Bavelier (2003) conclude about gamers' attentional abilities?

Gamers had improved capacity, spatial distribution, and temporal characteristics of attention.

In the context of video game training, what was the effect of training non-gamers for 1 hour per day for 10 days with 'Medal of Honour' compared to a control group playing 'Tetris'?

Non-gamers showed improved enumeration, enhanced useful field of view, and faster recovery from the attentional blink.

According to the study's findings, what cognitive improvements were observed in participants who played action video games?

Enhanced vigilance and better peripheral information processing.

Despite the improvements in vigilance and peripheral information processing, what aspect of cognitive function did the study find no change in?

Complex decision making

Why did the study suggest that action video games, particularly first-person shooter games, might lead to improved attention and peripheral information processing?

First-person shooter games involve task-switching and push the limits of attention.

Which of the following is a real-world benefit of action video game experience in the context of surgery?

Enhanced perception of 3D images, ambidexterity, and tone reflexes in trainees

How do action video game players perform in comparison to pilots when it comes to acquiring, identifying, and tracking targets in UAV piloting?

Action video game players outperform pilots in visually acquiring, identifying, and tracking targets

What does the information suggest about the driving performance of action video game players in simulated driving?

Action video game players show better driving performance in simulated driving

Study Notes

Multitasking and Task Switching

  • When individuals attempt to perform two or more tasks simultaneously, the typical outcome is a decrease in performance, as they are not able to process multiple tasks concurrently.
  • In experiments involving the simultaneous performance of two reaction time tasks, it is often observed that task performance is impaired, and reaction times are longer.
  • The phenomenon where individuals believe they are multitasking but are actually rapidly moving between tasks is commonly referred to as "task-switching."
  • The switch cost in multitasking scenarios refers to the time and efficiency lost when switching between tasks.

Task Switching and Brain Regions

  • The brain regions typically involved in task switching are the prefrontal cortex, basal ganglia, and anterior cingulate cortex.
  • The brain regions predominantly activated during switch trials in task switching are the dorsolateral prefrontal cortex and the anterior cingulate cortex.

Attention and Distraction

  • Attention can be directed in a top-down manner, which is goal-driven, or in a bottom-up manner, which is stimulus-driven.
  • Unintentional attention capture occurs when an individual's attention is drawn to a stimulus without their intention or awareness.
  • Visual distraction while driving can lead to a significant decrease in performance, and the consequence is an increased risk of accidents.

Visual Distraction and Driving

  • The three primary types of distraction while driving are visual, auditory, and cognitive distraction.
  • Visual tunnelling is a phenomenon where an individual's attention is focused on a specific stimulus, and they are unable to process other visual information.
  • The visual tunnelling effect is problematic when driving, as it can lead to a decreased ability to detect and respond to hazards on the road.

Attention Training and Video Games

  • The study by Sturm et al. (1997) trained participants on attention functions, including attentional control, attentional switching, and attentional monitoring.
  • The two attention functions that showed the most improvement as a result of the specific training in the study by Sturm et al. (1997) were attentional control and attentional switching.
  • The study by Green & Bavelier (2003) found that gamers had three attention-related advantages compared to non-gamers, including improved attentional control, attentional switching, and attentional monitoring.

Cognitive Improvements and Video Games

  • The study by Green & Bavelier (2003) concluded that gamers' attentional abilities were improved due to their experience playing action video games.
  • The study found that training non-gamers for 1 hour per day for 10 days with 'Medal of Honour' compared to a control group playing 'Tetris' led to improvements in attentional abilities, particularly in vigilance and peripheral information processing.
  • The study suggested that action video games, particularly first-person shooter games, might lead to improved attention and peripheral information processing due to the fast-paced and dynamic nature of the games.

Real-World Benefits and Action Video Games

  • The study found that action video game players have improved attentional abilities, which can lead to real-world benefits, such as improved performance in surgery.
  • Action video game players perform better in comparison to pilots when it comes to acquiring, identifying, and tracking targets in UAV piloting.
  • The information suggests that action video game players have improved driving performance in simulated driving, likely due to their improved attentional abilities.

This quiz explores the outcome of multitasking and its effects on performance. Discover whether attempting to perform multiple tasks simultaneously leads to enhanced performance, seamless attention division, a bottleneck, or improved speed of task execution.
