Motor Behavior #4
Motor Behavior Exam
| Question | Answer |
|---|---|
| task-intrinsic feedback | the sensory feedback that is naturally available while performing a skill |
| augmented feedback | a generic term used to describe information about performing a skill that is added to sensory feedback and comes from a source external to the person performing the skill; it is sometimes referred to as extrinsic or external feedback |
| knowledge of results (KR) | type of augmented feedback that provides information about the movement outcome |
| knowledge of performance (KP) | type of augmented feedback that provides information about the movement characteristics |
| quantitative augmented feedback | augmented feedback that includes a numerical value related to the magnitude of a performance characteristic |
| qualitative augmented feedback | augmented feedback that is descriptive in nature (e.g., using terms such as good, long), and indicates the quality of performance |
| performance bandwidth | in the context of providing augmented feedback, a range of acceptable performance error |
| descriptive KP | a verbal knowledge of performance (KP) statement that describes only the error a person has made during the performance of skill |
| prescriptive KP | a verbal knowledge of performance (KP) that describes errors made during the performance of a skill and states (i.e., prescribes) what needs to be done to correct them |
| concurrent augmented feedback | augmented feedback that is provided while a person is performing a skill or making a movement |
| terminal augmented feedback | augmented feedback that is provided after a person has completed the performance of a skill or movement |
| KR-delay interval | the interval of time between the completion of a movement and the presentation of augmented feedback |
| post-KR interval | the interval of time between the presentation of augmented feedback and the beginning of the next trial |
| subjective performance evaluation strategy | this requires the person to evaluate his or her own performance |
| guidance hypothesis | the role of augmented feedback in learning is to guide performance to be correct during practice; if it is provided too frequently, it can cause a learner to develop a dependency on its availability and therefore to perform poorly when it is not available |
| Prescriptive verbal KP is better than descriptive verbal KP for: | beginners |
| Do not feel compelled to give augmented feedback after: | every practice attempt. When you do not give augmented feedback, you provide opportunities for people to determine what their own sensory feedback tells them about performing the skill they are learning. |
| The performance-bandwidth strategy of providing augmented feedback can be: | especially useful when instructing groups of individuals where it is difficult to interact with each person individually on every performance attempt |
| On occasion, ask the people you are working with to tell you what: | movement errors they made and how they should correct them before you give them this information. |
