Question
In a reaction time experiment, a participant's reaction time improved from 0.30 seconds to 0.20 seconds after practice. Discuss how this change in reaction time can be explained by the functioning of the nervous system.
Answer
The improvement in reaction time from 0.30 seconds to 0.20 seconds suggests that the participant's nervous system became more efficient at processing the stimulus and executing a response. This could be due to increased myelination of neurones or improved synaptic transmission, allowing for faster signal conduction.
Explanation
This answer is strong as it explains the physiological changes in the nervous system that can lead to improved reaction times. The question tests the application of knowledge regarding the nervous system's role in reaction time and the impact of practice on neural efficiency.
Common mistake
Misinterpreting Reaction-Time Data
Students often misinterpret the significance of reaction-time data, confusing faster reaction times with better overall performance without considering the context of the experiment.
To fix this, students should focus on understanding the specific conditions of the experiment and how they relate to the reaction times, ensuring they analyze the data in context rather than in isolation.
