Suppose the large number of auto accidents in a small town results in new legislation that requires all dtizens of the town to installnow anti-lock brakes on their cars. These new brakes cut the time it takes a car to stop by 50%, allowing drivers to more easily avoid collisions with other cars and The new brakes decrease the probability that a vehicle will colde with another vehicle but also gives drivers an incentive to drive more , which could potentially decrease the number of car accidents in the town.

decrease, recklessly, increase and decrease

Explanation:

As it is mentioned in the question that there is a decrease in time by new brakes that stops the car which helped the car driver to avoid the collisions

Here, the probability is reduced due to which a vehicle is collide with the other vehicle but it also generated an incentive to drive more in recklessly manner than result in rise in the car accident numbers

Also, due to the establishment of new brake the stopping time could be decreased

As the establishment of new brake, the driver provides the incentive as they are very familiar to stop the car as it is faster comapred with the old brake due to which the accidents numbers rises

i believe the answer is:   psychological  experiment

in this experiment, wilhelm wundt became the first person that implement scientific method in analyzing the pyschological phenomenon.

due to this result, wilhelm wundt also able to make psychology to be acknowledged as a separate scientific field from biology.
