Can Training Eyemovements Hinder Visual Search?

Summary, in English

There have long been assumptions about optimal visual

strategies for specific tasks, arising from the differences noted

between experts’ and novices’ eye movements in domains as

diverse as reading, driving, rifle shooting, and cricket. However,

because there remains a gulf between theoretical models of eyemovement

control (e.g Findlay & Walker, 1999) and their use in

applied contexts, simply training novices eye-movements to

resemble those of experts may not lead to improvements in

performance (Donovan, Manning, Phillips, Highman, &

Crawford, 2005). It is plausible, based on Findlay & Walkers

model of saccade generation, that only training people where to

look actually hinders the ability to process foveated stimuli (via

activation of the centre concerned with generating saccades and

inhibition of the centre concerned with maintaining fixation). A

series of experiments attempts to demonstrate this result,

suggesting that optimal training for complex visual tasks should

focus both on saccades and fixations.
