OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Choice and Consequence in Eye Movements and Beyond
Deciding how to allocate your attention and efforts when faced with multiple competing goals is a dilemma we all face in daily life. These decisions can have serious consequences — for example, in splitting your attention while driving, or helping multiple casualties in an emergency. An important factor that should weigh into such a decision is the limitations of your own abilities. That is, if you have adequate time and skill, you can complete multiple tasks in a given time interval, but if the tasks are difficult and time is limited, you should focus your efforts on completing one task. Using eye movements as a starting point, we have shown that people fail to take the limitations of their own visual acuity into account when deciding where to look. We have extended this decision paradigm beyond eye movements into several other tasks (throwing, reaching to targets, memorisation), with the same results: people fail to take into account their own (known) performance limitations when deciding how to allocate resources between two goals. After ruling out a number of simpler explanations, I will speculate on why people make these surprisingly inefficient decisions.
