Question

what did a study by strayer and johnston (2001) regarding the effects of attention on driving conclude?

Answer 1

Attention is not affected as long as one is using a hands-free phone.

• In a driving simulation, participants were shown to be more likely as compare to miss simulated traffic signals when speaking than when not conversing, according to Strayer and Johnston (2001). For both hand-held and hands-free cell phone users, movement performance reductions were comparable.
• Dual-task methodology was used by Strayer and Johnston (2001) and Strayer, et al. (2003) to determine whether talking on a mobile phone while driving would cause attention to be divided between the external visual field and the interior cognitive processes involved in a cell phone conversation.
