Accuracy vs Precision
This refers to how close a movement is to the target value.
What is accuracy?
This error measures directional bias (overshoot vs undershoot).
What is constant error (CE)?
The interval between stimulus presentation and movement initiation.
What is reaction time (RT)?
This process prepares the sequence of action that will result in movement before execution.
What is motor programming?
This model converts goals into motor commands.
What is the inverse model?
This reflects consistency across repeated trials
What is precision?
This error ignores direction and only considers magnitude.
What is absolute error (AE)?
The interval between movement initiation and completion.
What is movement time (MT)?
This type of control relies on external stimuli.
What is reactive control?
Learning driven by sensory prediction errors is called ___.
What is error-based learning?
A performer consistently overshoots the target but with low variability. This indicates high ___ and low ___.
What is high precision and low accuracy?
This error reflects consistency across trials and is often expressed as SD.
What is variable error (VE)?
This stage involves perceiving that the light turned out indicating it is time to respond.
What is stimulus identification?
This type of control relies on internal prediction.
What is predictive control?
Learning driven by rewards and success/failure.
What is reinforcement learning?
This type of error reflects systematic bias in performance.
What is constant error?
If the mean error is not zero, this indicates ___.
What is bias?
This stage involves choosing an action among alternatives.
What is response selection?
The brain sends this to predict sensory consequences of movement.
What is an efference copy?
This type of learning strengthens movements through repetition.
What is use-dependent learning?
This type of error increases variability without shifting the mean.
What is random error?
Comparing performance across different target sizes is best done using this type of error.
What is relative error?
Donders used this method to estimate processing time.
What is the subtraction method?
This model predicts what will happen after a motor command.
What is a forward model?
Mismatch between predicted and actual sensory feedback produces this.
What is sensory prediction error?
