    Study Notes

    Multitasking

    • Multitasking is performing two or more tasks simultaneously.
    • Learning objectives focus on understanding divided attention, empirical work on mobile phones and driving/walking, task switching, multimedia multitasking, and whether multitasking is beneficial. Supertaskers are also discussed.

    Divided Attention

    • Divided attention is the ability to respond to multiple tasks or demands at the same time.
    • Factors like task difficulty and task similarity affect divided attention.

    Practice

    • Schneider and Shiffrin (1977) demonstrated the impact of practice on multitasking.
    • Participants were shown a target stimulus, followed by a rapid series of test frames.
    • The task required retaining the target in memory and checking if it appeared in the test frames.
    • Performance improved with practice, eventually reaching automaticity after about 600 trials.

    Task Difficulty

    • Task difficulty influences divided attention.
    • More challenging tasks make multitasking more difficult.

    Task Similarity

    • Similar tasks are harder to perform concurrently (multitask).
    • McLeod (1977) demonstrated this effect.

    Mobile Phones and Driving

    • Strayer and Johnson (2001) found that using a mobile phone significantly decreased reaction time and increased missed red lights in a driving simulation.
    • Phone use impacts driving, whether hand-held or hands-free.
    • Redelmeier and Tibshirani (1997) showed a quadruple increase in collision risk for drivers using a mobile phone.
    • Caird et al. (2008) found that reaction times increased by 250 milliseconds when participants used phones.

    Typing and Driving

    • Typing and reading text messages negatively impacted eye movements, stimulus detection, reaction time, collisions, and driving performance.
    • Studies show that texting and driving significantly increases collision risk.

    Driving and Phone Use

    • Strayer et al. (2003) studied the effect of phone use on driving in traffic simulations.
    • Results showed that hands-free phone use could still impair performance, particularly in complex or high-traffic situations.
    • Other studies also indicate that conversations or the usage of phone functions impacts driving negatively.

    Automated Driving Systems

    • Wanda et al. (2018) investigated response times to critical tasks while driving in highly automated systems, and during non driving related tasks.
    • Response times were longer when the non-driving task was visual-vocal or visual-manual, e.g., reading or writing text messages.

    Talking to Passengers

    • Conversations with passengers can be different than conversations on phones.
    • Context impacts the complexity of a conversation, which might decrease the potential for negative effects on the driver.
    • Conversations with passengers can often lead to more situational awareness and could decrease driver distraction risk.
    • Studies have shown differences in attention, distraction, and performance based on types of conversations and passengers.
    • Hyman et al. (2010) studied walking behavior and conversations while using phones, showing poor performance in both tasks.

    Task Switching

    • Task switching involves shifting attention between different tasks.
    • Switching costs include slower performance and decreased accuracy.
    • Using a phone, in particular, causes greater switching costs.

    Multimedia Multitasking

    • OFCOM (2021) report showed increased online activity, including the use of multiple devices/media at once (i.e., phone and TV).
    • Ophir et al. (2009) studied individuals high and low in multimedia multitasking levels/frequency and found reduced cognitive control in heavy multitaskers.
    • The study indicated worse task-switching abilities with heavy multitaskers.

    The iPhone Effect

    • 200 participants took part in a study where conversation quality was measured to see how mobile phones might impact real-life interactions.
    • Presence of a phone reduced interpersonal connectedness.
    • Also studied if the type of conversation affected interpersonal connectedness and how phone use impacted conversation quality.

    Supertaskers

    • Individuals with exceptional multitasking skills show a pattern related to other studies, and were studied using specific tests.
    • Watson and Strayer (2010) used the OSPAN task and driving simulations to measure multitasking abilities in a study.
    • Performance was markedly inferior when multitasking.
    • Multitasking decreased performance in a variety of tasks.
