ch. 8 Flashcards
_________ requires the organization of multiple moving parts of the motor system
Coordination
T or F: actions with different temporal organization are easily coordinated
False
the same
What are discrete tasks?
tasks that have a definitive start and end points
Give an example of a discrete task
Turning on a light switch
T or F: discrete tasks involve slow and methodological preplanned movements
False!
rapid, preplanned movements
According to ________ grip-formation is responsible for preparing the hand to capture the object
Jennerod
Jennerod: In the second phase, what are the fundamental components of reaching and grasping?
hint: there are 2
- transport component
2. grip formation component
Viewer-centered perspective
An objects extrinsic properties (distance, location, or both) are used to plan the details of limb transport
Viewer-centered perspective: grip formation is determined by…
the object’s intrinsic properties (the material from within - i.e. what the object is made of)
Spatial planning: _________ suggest that reach and grasp action requires aiming the thumb at an object followed by shaping the fingers as appropriate to acquire the object
Wing et. al.
Discrete bimanual actions
One’s limb movements are shown to influence both temporal and spatial actions of the other limb
Give 3 examples of discrete bimanual acitions
Tying shoe laces, eating with a fork and knife, and grating cheese
Coordination of difficulties is solved by the creation of…
a new GMP (generalized motor program)
T or F: continuous tasks are reliant on GMPs
False
continuous tasks are NOT dependent
T or F: it has been theorized that patterns are self organizing
true
