Option 2
The speed-accuracy trade-off is a phenomenon in which people tend to make more errors when they try to perform a task quickly. This is because they do not have enough time to process all the information they need to make a correct decision. On the other hand, if people take more time to perform a task, they are more likely to make fewer errors. However, this also means that they will be slower.
Option 1 is not a speed-accuracy trade-off because it does not mention the relationship between speed and accuracy. It simply states that people tend to make more errors when movement time increases. This could be due to a number of factors, such as fatigue, distraction, or lack of practice.
Option 2, on the other hand, does mention the relationship between speed and accuracy. It states that people tend to reduce their speed when spatial accuracy is needed. This is because they know that if they rush, they are more likely to make a mistake.
In other words, option 2 describes a situation in which people are willing to sacrifice speed in order to improve accuracy. This is the definition of a speed-accuracy trade-off.
Here is an example of a speed-accuracy trade-off:
- You are trying to hit a target with a dart. If you throw the dart quickly, you are more likely to miss the target. However, if you take your time and aim carefully, you are more likely to hit the target.
In this example, there is a clear trade-off between speed and accuracy. If you want to hit the target, you need to be both fast and accurate. However, if you try to do both at the same time, you are more likely to make a mistake.
