Which physiological effect is NOT typically experienced by a driver during a pursuit?

During a pursuit, drivers often experience heightened stress and physiological responses due to the adrenaline rush associated with high-stakes situations. This adrenaline surge may lead to various effects, including tunnel vision, which narrows the visual field to focus on immediate threats or targets. Driver fixation on a particular object or event, commonly referred to as target fixation, can also occur, causing the driver to become overly focused on a single point instead of maintaining awareness of the broader environment.

Enhanced memory retention, on the other hand, is not a typical effect experienced during high-stress situations like a pursuit. In fact, the stress of an adrenaline-inducing event can often impair memory recall and hinder the ability to process information effectively. The intense focus and anxiety can detract from cognitive functions that are crucial for retaining memories, making it less likely for a driver to remember details clearly after the pursuit is over. Thus, the absence of enhanced memory retention stands out as the correct answer in this context.
