In each epoch, one of three predators representing different levels of threat (corresponding either to chase speed or wake-up probability, in different versions of the task) was present but inactive in a corner of the grid.
Shows like "Cops," on Fox, which follows real-life deputies and police officers as they raid crack dens, break up domestic disputes and chase speeding cars, have proven appeal.
"What we are chasing is speed.
Many a rider has made the error of moving too early when chasing such speed.
We conducted three independent experiments involving 24, 25, and 19 healthy volunteers respectively, varying preassessment training (no training, 600 epochs, 480 epochs), epoch duration, and implementation of threat level (experiment 1, chase speed; experiments 2 and 3, wake-up probability).
Angular velocity differed with prey (χ = 27.58, p < 0.001) and, while chase speed was not related to hunt success (χ = 1.15, p = 0.284), angular velocity during the last 5 s was significantly greater when hunts were successful (χ = 13.44, p < 0.001).
Finally, females that vocally interacted with pursuing males had lower chase speeds than silent females, suggesting a role for these exchanges in communicating female receptivity.
In the storm chasing community, needing speed typically means you're too close to a storm.
Urges we get in own taxi and rush up to Harlem, Bronx, etc., and try to chase down speeding suitcase.
That is the appeal of private-probation firms: small fines often go unpaid because local governments cannot afford to chase every speeding ticket.
